Revision of the genus Dellia Stål , 1878 ( Orthoptera : Acrididae ) . Part 1 . Two redescriptions and seven new species from Cuba

The first part of the revision of genus Dellia Stål, 1878, comprising Cuba in the Greater Antilles, is presented here. Dellia insulana Stål, 1878, the type-species, is redescribed and illustrated for the first time. Dellia multicolor Carl, 1916 stat. resurr. is restored as valid species, redescribed from both sexes, illustrated for the first time, its type locality is defined and its geographical distribution is clarified. Seven new species are also described: Dellia albida n. sp., Dellia atrostriata n. sp., Dellia brauni n. sp., Dellia megalapida n. sp., Dellia melici n. sp., Dellia siboney n. sp., and Dellia zephyra n. sp. All nine species are described and compared in detail, supported by a thorough photographic complement.


Introduction
The grasshopper genus Dellia was described by Stål (1878) as monotypic, with its single, Cuban endemic member Dellia insulana Stål, 1878.Almost 40 years later, Dellia multicolor Carl, 1916 was described from two adult females collected by Henri de Saussure in "Cuba" (without further precision), but it was deemed a synonym of D. insulana by Amédégnato et al. (1995).
No further additions or emendations to the taxonomy of Dellia have been produced thereafter, and the genus remains endemic from the Greater Antilles with 10 nominal species: six from Hispaniola (Dominican Republic only), three from Jamaica and one from Cuba.The undetermined Dellia sp. from Bahamas recorded by Perez-Gelabert (2000), is still awaiting a formal description.
The present author is currently conducting a thorough revision of some Caribbean orthopteroid groups, including the genus Dellia.As part of this, seven new species from Cuba are herein described, D. insulana is redefined and D. multicolor stat.resurr.is resurrected from synonymy and its adult male is described, following the current methodological standards in Acrididae taxonomy.Also, in this first part of the revision, the type locality of D. multicolor stat.resurr.is defined and the genus is confirmed to occur in multiple localities all over the main island of Cuba.Moreover, the first precise distribution records as well as abundant data on the natural history of most Cuban species are given.A thorough photographic complement of live and preserved specimens, habitat and microhabitat, detailed maps and dichotomic key to the identification of all species is also provided.

Material and Methods
The grasshoppers were detected mainly on the vegetation by diurnal, crepuscular and nocturnal direct search.Once spotted, high resolution, full-color digital photographs were taken (habitat included) with a Nikon Coolpix S8100 digital camera.Then, all specimens were sacrificed by either exposition to ethanol 70% vapors or immersion in the same liquid; final preservation was made either in ethanol 80% or dry-pinned.
Unless otherwise noted, the described coloration was taken following a methodology adapted from that used by herpetologists (see, e.g., Köhler & Hedges, 2016) and is detailed as follows.It is well-known that the two main methods of insect preservation, i.e., dry-pinned or stored in ethanol, cause some undesirable alterations to the morphology and/or coloration.On one hand, alcoholic preservation may cause loss or severe alteration of some colors and shades, which usually become either faded or greatly changed.On the other hand, dry-pinning brings the inherent risk that specimens and their labels may be destroyed, mutilated or fragmented by collection pests (rodents, dermestid beetles and psocids), become brittle and distorted due to dehydration, and setae are usually detached and lost.The best strategy is to take highresolution, full-color photographs of the specimens still alive or just after being killed (i.e., before any color or shade becomes altered) for an accurate description of coloration, and then to preserve them in ethanol or isopropanol 80%.Permanent alcoholic preservation not only avoids all these problems of dry-pinning mentioned above, but also has the additional advantage of yielding more suitable specimens for dissection of genitalia and DNA extraction.
The specimens were studied, measured and photographed under a Zeiss Stemi 2000-C stereomicroscope, equipped with line scale and grid ocular micrometers, and a Canon PowerShot A620 digital camera.The digital images were processed with Adobe Photoshop CS3 only slightly, i.e., optimization of brightness and contrast parameters, background removal and plate composition.
Two structures proved difficult to measure accurately by being partially to largely hidden below pronotum: tegmina and mesonotum.The former could be reliably measured because in Cuban taxa they are always strikingly colored and could be observed with confidence through the translucent tegument of the pronotum.But the latter lacks any contrasting coloration or especial sclerotization and could not be measured.
Specimen labels were laser-printed in Spanish, but transcribed here into English for text coherence purposes.Precise coordinates and altitude of each locality were either directly taken in situ with a portable GPS device or extracted from updated 1:25 000 military topographic maps in Mapinfo 9.0.
The general terminology follows Capinera et al. (2004), Fontana et al. (2008) and Aguirre-Segura & Barranco Vega (2015); such diversity of sources is currently unavoidable because none of them covers the whole range of structures and terms.Taxonomic arrangement was verified using the Orthoptera Species File Online website (OSF), version 5.0/5.0 (Cigliano et al., 2016).All meristic counts were given as fractions for left/right sides.
Depositories of types and other specimens are abbreviated using the following acronyms: MHNG: Muséum d'Histoire Naturelle de Genève collection, Switzerland.

Comparisons.D. insulana is very easy to separate from the other 17 members of the genus by its unique color pattern, i.e., largely plain green, with no sharply contrasting patterns except for a single blurred dark lateral stripe along each side of the body (figs.[1][2].Distribution (fig.24).This species is known only from the holotype, whose label does not bear any precision on locality but "Cuba" (Stål, 1878).

Ecological notes.
Nothing is known about the ecology of D. insulana.This requires its rediscovery and/or elucidation of its geographical occurrence.
Despite its type labels and code number from NHRS collection, this female is not an actual type of D. insulana.The original description was explicitly stated by Stål (1878: 83-84) to be based upon a single male specimen, which fulfils completely the Article 73.1.2 of the Code about holotype fixed by monotypy (ICZN, 1999: 65).This holotype is the same specimen examined here, as confirmed by its absolute coincidence with the characters and measurements given by Stål (1878: 83-84).Moreover, the female specimen is not even conspecific with D. insulana but can be referred to D. multicolor stat.resurr.instead, as it is evident from its very different color pattern (compare figs.1-2 to 3 herein).Carl, 1916: 512-513. Rehn & Hebard, 1938: 224. Dellia insulana: Amédégnato et al., 1995: 694 (misidentification).

Head (figs. 16-18).Moderately large, wider than long (ratio = 1.3).Tegument shiny, but sparsely and coarsely punctate, with thin and short setae scattered all over.Vertex convex in lateral view, subtriangular in dorsal view; fastigium prominent, broad in dorsal view, semicircular in lateral view and strongly compressed in frontal view.Eyes very large, rounded and prominent; ocelli minute.Costa frontalis very well-marked and keyhole-shaped, with lateral branches almost parallel and shallowly sinuose, i.e., upper portion wider and inverted U-shaped, lower portion narrower and almost circular.Genae almost straight in frontal view, but not flat.Frons coarsely and sparsely punctate.Antennae standard for Acrididae in size and shape, with 18/18 flagellomeres; scapus subcylindrical, wider than long (ratio = 1.1), oval in cross-section, mostly glabrous; pedicel clearly of more than half the length of scapus.
Thorax (figs. 19-20).Tegument shiny, but densely and coarsely punctate and with thin, short setae scattered all over.Pronotum subrectangular in dorsal view, longer than wide (ratio = 1.1); anterior and posterior margins clearly bilobed, the former shallowly notched medially, the latter moderately notched medially, lateral margins shallowly sinuose; median keel strong, lateral keels irregularly crenulate and deeply incised by the three transverse grooves.Metanotum wider than long (ratio = 2.3) and shorter than abdominal segment I (ratio = 0.7), trapezoidal in dorsal view with tegument coarsely punctate and shiny.Tegmina very short (reaching anterior margin of abdominal segment I), narrow and digitiform, costal margin basically straight, anal margin slightly sinuose and tip rounded.

Comparisons.D. multicolor stat.resurr.is easy to distinguish from the other 17 members of the genus by its unique color pattern, i.e., head and pronotum with four solid alternate stripes of vivid green and yellow, combined with lower half of abdomen uniformly bright red (figs. 5-6).
Distribution (fig.24).This species is confirmed to occur only in northwestern Cuba, in northern Havana-Matanzas Coastal Plain.

Ecological notes.
As usual for ordinary members of the genus, D. multicolor stat.resurr.seems to be rare and/or highly localized.The Havana-Matanzas Coastal Plain is undoubtedly the longest and most intensively sampled region in Cuba, but only four specimens have been collected and a single precise locality is confirmed.There at Boca de Canasí, the same situation holds true: despite multiple and intensive day-andnight searches, the two available specimens were found together at the same spot.These specimens from Boca de Canasí were found at dusk, standing in close proximity on the same twig of the bush Zanthoxylum fagara (L.) Sarg., 1890 (Rutaceae), less than 1.0 m above the ground, in a sea grape forest.Repeated searches at the same spot and surroundings (including the adjacent semicaducifolious forest and xerophytic scrub), were totally unsuccessful.
One of the males from Boca de Canasí had an unidentified egg-like organism attached to right epimeron II.The other was taken as subadult and molted to adult at night, a few hours after collection.
Remarks.The comparison of the name-bearing types of D. insulana (holotype) and D. multicolor stat.resurr.(lectotype), plus two additional, fresh adult males of the latter, revealed that both taxa are clearly not conspecific.Such synonymy was introduced by Amédégnato et al. (1995) as follows: "The synonymy of both specific names is unquestionable from the study of the types of both species and the comparison of their photographs.The differences annotated by Carl (1916) do not exist in the specimens with respect to the ovipositor.Its distinct coloration corresponds to that specified by Zayas (1976) and we believe it is due to intraspecific variability" (Amédégnato et al., 1995: 694; originally in Spanish, italics and English translation added herein).Nevertheless, such arguments were actually flawed: 1. Amédégnato et al. (1995) wrongly regarded the holotype and the false type of D. insulana (same two specimens examined herein) as conspecific and mistook the evident differences as intraspecific variation, apparently by regarding them as sexual dimorphism.

2.
Because the false type of D. insulana is very similar in coloration to the lectotype of D. multicolor stat.resurr.designated by them (see figs. 3 and 6 herein), Amédégnato et al. (1995) also wrongly concluded that both taxa were conspecific, missing the crucial point that the identity of the former is indivisibly linked to its name-bearing type, i.e., the holotype male.
3. Amédégnato et al. (1995) trusted the D. insulana concept of Zayas (1976), who nevertheless did not study its holotype nor the (then) syntypes of D. multicolor stat.resurr.and even did not mention the latter.Strangely, they overlooked an interesting comment given on the same page: "It looks like there are many species members of this genus..." (Zayas, 1976: 100; originally in Spanish, italics and English translation added herein).
The present study of multiple samples where both sexes of the same species are included (e.g., D. atrostriata n. sp., D. megalapida n. sp. and D. multicolor stat.resurr., plus the available literature on Hispaniolan and Jamaican taxa) revealed that adult intraspecific variation is virtually nonexistent and sexual dimorphism is largely restricted to genitalia and does not affect the color pattern (i.e., males are slightly smaller and more slender than females and their coloration is only subtly brighter, but keeps exactly the same pattern).
On the basis of the argumentation given above, D. multicolor Carl, 1916 is herein restored as valid species and the following differences support its accurate distinction from D. insulana: 1. General coloration.D. multicolor stat.resurr.: sharply contrasting, head and pronotum with four solid alternating stripes of vivid green and yellow, abdomen with lower half uniformly bright red.D. insulana: plain, basically olivaceous green, only with a blurred pair of dark brown lateral stripes.See figs.2, 5-6.The exact locality and collection date of the types of D. multicolor stat.resurr.were not stated in the original description, nor included in their labels (fig.4c); nevertheless, there is a supplementary literature source that clarifies both data.Hollier & Hollier (2012: 238) reported that Saussure traveled to Cuba from January 29 th through February 22 th , 1855, and visited the following localities: Havana, Guanabacoa, Santa María del Rosario, Matanzas and Limonar.

Variation.The small juvenile female paratype has a strikingly different coloration (fig.8): almost the entire body and appendages light gray with a dense pattern of small dark grey spots, except for the antennae (annulated all along in dark grey and pale green), sternites (pale green) and hind leg femur and tibia (the former pale green with blackish spots on outer surface mostly over transverse ridges, the latter pale gray, basally blackish and with ventral half conspicuously infuscate).This specimen also has very short tegmina that barely reach the posterior margin of mesonotum, a common eval variation in Acrididae.
Comparisons.This species is most closely related to D. siboney n. sp., sharing color pattern and morphological features such as the coloration of pronotum, transverse ridges of the hind femur, abdominal tergites and general shape of the body.Nevertheless, D. albida n. sp.can be easily distinguished from the latter by the following characters: 1. Coloration of body.D. albida n. sp.: predominantly vivid green, with head and dorsum of thorax bright white, anterior margin of pronotum concolor.D. siboney n. sp.: predominantly reddish, including head and dorsum of thorax, anterior margin of pronotum sharply outlined with bright white.See figs.7, 14.  24).This species is known only from the type locality, on the southern slope of the eastern edge of the Cordillera del Turquino.This chain represents the main western subdivision of the Sierra Maestra Range.

Ecological notes.All types of this species were found in the afternoon in the small garden of a house (meteorological station), surrounded by montane rainforest (fig.26d).Repeated and intensive searches in surrounding areas with both primary and secondary vegetation (rainforest, pine forest, pasture and other gardens), were totally unsuccessful.In this spot, D. megalapida n. sp. is nevertheless common, i.e., it is usual to spot several specimens per sampling, although a very careful search must be done to achieve success.
Individuals were found on different garden plants, even though most of them preferred a single undetermined species of Apiaceae (fig.25i, 26d).All were standing on fine twigs and stems very close to the ground (not more than 0.3 m up), in normal activity, mostly feeding.One mating pair was found on 23/July/2017 (fig.25h).

Ecological notes.
According to the field notes of the collectors (Beatriz Lauranzón and Jorge L. Reyes, pers.comm.), the single known specimen was captured in the backyard of an abandoned house, while sweeping with an entomological net the low bushes Stachytarpheta jamaicensis (L.) Vahl, 1804 (Verbenaceae).The primary vegetation around the site is microphyllous semicaducifolious forest and subcoastal xerophytic scrub, both on limestone karstic terrain (fig.26g).
This species seems to be quite rare.No more specimens were found along with the holotype, despite net-sweeping during a whole day by two persons (Beatriz Lauranzón and Jorge L. Reyes, pers.comm.).Moreover, on 2/November/2017 and 1/December/2017, the present author and one skilled collaborator attempted to find D. siboney sp.n. again at the exact site and surroundings, but no success was achieved although the search was conducted continuously from morning through early night, including both netsweeping and careful visual inspection of the vegetation.

Head (figs. 16-18).Moderately large, wider than long (ratio = 1.3).Tegument shiny, but sparsely and moderately punctate, with thin and short setae scattered all aver.Vertex moderately convex in lateral view, subtriangular in dorsal view; fastigium prominent, broad in dorsal view, slightly convex in lateral view and strongly compressed in frontal view.Eyes very large, rounded and prominent; ocelli minute.Costa frontalis weakly marked and invertedly U-shaped, i.e., upper portion wider and the lower portion narrower.Genae moderately convex in frontal view.Frons moderately punctate.Antennae standard for Acrididae in size and shape, with 19/19 flagellomeres; scapus subcylindrical, depressed, longer than wide (ratio = 1.1), oval in cross-section, essentially glabrous; pedicel clearly more than half the length of scapus.
Thorax (figs. 19-20).Tegument shiny but densely and moderately punctate and mostly glabrous but with thin and short setae scattered all over.Pronotum sub-trapezoidal and slightly tapering anteriorly in dorsal view, wider than long (ratio = 1.2); anterior margin shallowly sinuose, posterior margin shallowly bilobed and incised medially, lateral margins convex sinuose; median keel deeply marked, lateral keels sparsely crenulate and deeply incised by the three transverse grooves.Metanotum wider than long (ratio = 3.3) and shorter than abdominal segment I (ratio = 0.5), rectangular in dorsal view, short, with tegument feebly punctate and shiny.Tegmina very short (reaching anterior margin of abdominal segment I), narrow and digitiform, i. e., costal and anal margins slightly convex and tip convex.
Abdomen.Moderately large and slender (conspicuously narrower than pronotum), subcylindrical and evenly tapering posteriorly.Tegument shiny and feebly punctate, with small scattered setae and abdominal segments with median carina very well marked.Tympanic organ large, oval, located laterally on segment I. Supra-anal plate (fig.21) relatively large, narrowly paraboloid, longer than wide (ratio = 1.3) and sparsely setose; median sulcus complete, shallow and very narrow, flanked by a pair of low, coarse, parallel         ridges.Cerci very short, conical and densely covered by thin setae, not surpassing apex of posterior margin of supra-anal plate and abdomen.Subgenital plate (fig.23), longer than wide (ratio = 1.0); anterior margin slightly convex, lateral margins essentially straight, posterior margin strongly convex and with a strong and thin V-shaped median projection.Ovipositor in lateral view: each valve of the dorsal pair with dorsal surface basically straight, with several indistinct, low crenulations and apically shallowly curved upwards; each valve of the ventral pair with ventral surface shallowly convex, with several crenulations and apically curved downwards.See figures 15, 21-23 and table I.

Male: Unknown.
Comparisons.This species is most closely related to D. brauni n. sp., D. megalapida n. sp. and D. roseomaculata, by sharing a similar combination of color pattern (dorsum and venter of a different but rather uniform color, both separated by two solid stripes, i.e., upper dark and lower white, plus epimera I and II each with a large vivid red spot) and shape of the male supra-anal plate (basal portion subrectangular, apical portion subtriangular).But D. zephyra n. sp.can be easily distinguished from them by the following characters: 1. Coloration of dorsal body surface.D. zephyra n. sp.: light orange-brown.D. brauni n. sp.: intense blue.D. megalapida n. sp.: pale blue.D. roseomaculata: grayish blue.

2.
Coloration of hind femur.D. zephyra n. sp.: vivid green, slightly darker on transversal ridges and upper and lower margins, hind knees entirely black.D. brauni n. sp.: vivid olive-yellow, transversal ridges and upper margin vivid green, hind knees almost entirely black, only with lower half of outer surface brownish.D. megalapida n. sp.: vivid yellowish-green with outer surface vivid green, transversal ridges immaculate, hind knees with upper margin vivid light red and lower margin with a small blackish spot.D. roseomaculata: reddish with outer surface dark olive-bluish, transversal ridges immaculate, hind knees reddish-brown.Distribution (fig.24).This species is known only from the type locality, on the southern coast of the extreme western tip of Cuba.

Coloration of ventral
Ecological notes.The holotype of D. zephyra n. sp. was captured deep inside the dark zone of a cave, sitting on a wall about 1.8 m above the ground (T.M. Rodríguez-Cabrera, pers. comm.).This is an obvious serendipity; this specimen clearly entered the cave by accident through any of the several skylights or small forested dolines existing along its main passage.The vegetation outside the cave is a well-preserved subcoastal semicaducifolious forest, on karstic limestone terraces.
Remarks.The private collection of the late Fernando de Zayas (Havana, Cuba) houses another female of this species, which was seen by the author in September 2013.Its origin is declared on the label as Guanahacabibes Peninsula only (without any precise locality) and it was not studied in detail, thus, it was not given type status herein.

General remarks
The following key is based on coloration of live specimens and allows a reliable identification of adults of all species:
