Re-characterization of two Lithosiini species recently described from the island of Taiwan, with establishing of a new combination and the corrected checklist of the genus Aberrasine Volynkin & Huang, 2019 (Lepidoptera: Erebidae: Arctiinae: Lithosiini)

Two species recently described from Taiwan Island, Ammatho shiou Wu & Kishida, 2020 and Aberrasine lichenshihi Wu & Kishida, 2020 are re-characterized due to their genitalia wrongly illustrated in the original paper. A new combination is established: Aberrasine shiou (Wu & Kishida, 2020), comb. nov. 8 colour and 8 black and white diagnostic figures are included.


Introduction
The genus Aberrasine Volynkin & Huang, 2019 was erected by Volynkin et al. (2019b) with Miltochrista aberrans Butler, 1877 as the type species. The authors included 14 species and one subspecies into the genus. However, two species, A. dentata (Wileman, 1910) and A. marginis (Fang, 1991) were included to the genus erroneously as they belong to the subgenus Striatella Volynkin & Huang, 2019 of the genus Ammatho Walker, 1855 in fact. Wu & Kishida (2020) described three new species of the Asura / Miltochrista generic complex from Taiwan. One of them, A. lichenshihi Wu & Kishida, 2020 was correctly assigned by authors with the genus Aberrasine but instead of its female genitalia those of an unidentified species of the genus Nephelomilta were illustrated and described. Another new species, A. shiou Wu & Kishida, 2020 was erroneously described with the male genital capsule belonging to one of species of the subgenus Striatella of the genus Ammatho, which was a reason of description of the species under the genus Ammatho and not Aberrasine.
In the present paper, I correct all the mistakes listed above: exclude dentata and marginis from Aberrasine, establish a new combination: Aberrasine shiou (Wu & Kishida, 2020), comb. nov., recharacterize the two recently described species comparing them with the closest relatives and provide the corrected checklist of the genus Aberrasine below.

Material and methods
The genitalia were dissected, stained with eosin B and mounted in Euparal on glass slides using standard methods of preparation (Lafontaine & Mikkola 1987;Fibiger 1997). Photos of imagoes were taken using a Nikon D3100/AF-S camera equipped with Nikkor, 18-55 mm lens. Genital images were taken by the same camera attached to a microscope with an LM-scope adapter.
Diagnosis. Aberrasine shiou is very similar externally to the form of A. aberrans lacking a discal spot of the forewing, but can be distinguished by its markedly less curved posterior part of the medial transverse fascia and the somewhat shorter subterminal area of the forewing. The male genitalia of A. shiou are very similar to those of A. expressa (Figs 3, 4, 10, 14) which is easily separable externally by its smaller size and dissimilar forewing markings. Compared to that of A. expressa, the male genital capsule of A. shiou has the somewhat thicker uncus, the slightly shorter vinculum, the broader valva with the more convex costa, the larger distal costal process directed rather dorsally (whereas it is smaller and directed distally in A. expressa), and the more robust distal saccular process. The vesica configuration of A. expressa is unknown, but the smaller cluster of spines is wider and the elongate cluster of spines is conspicuously longer in A. shiou. The female genitalia of A. shiou differ from those of A. expressa by the longer apophyses anteriores, the shorter and narrower ductus bursae, the shorter corpus bursae with the spinulose posterior section (it is evenly weakly sclerotized and lacking spinules in A. expressa), and the somewhat longer appendix bursae more densely covered in larger spinules.

Aberrasine lichenshihi
(2) In the original diagnosis (Wu & Kishida 2020), the species was compared with the genitally rather dissimilar A. aberrans and not the closely related A. dingjiai (Figs 7,8,12,16) described recently from Lanyu Island (Hsu et al. 2018). The comparison with the latter is provided below.
Diagnosis. Aberrasine lichenshihi is similar externally to A. aberrans (illustrated by Volynkin et al. 2019b andWu &Kishida 2020) and A. peraffinis (illustrated by Volynkin 2018), but differs from the former one by its slightly more reddish forewing coloration and the posterior part of the medial line curved closer to the antemedial line (in A. aberrans, the area between the lines is markedly wider), and from the latter one by the antemedial line more strongly angular in the cell and the sinuous medial line (it is nearly straight in A. peraffinis). The male genitalia of A. lichenshihi are very similar to those of A. dingjiai which has clearly different forewing pattern. The male genital capsule of A. lichenshihi differs from that of A. dingjiai by the longer and wider distal section of costa which is more strongly curved dorsad, and the somewhat larger ventral plate of the costa. The aedeagus of A. lichenshihi is conspicuously smaller than that of A. dingjiai. Compared to that of A. dingjiai, the vesica of A. lichenshihi is narrower and slightly shorter, the elongate cluster consists of thinner but more numerous spines, and the smaller cluster of spines is wider. In the female genitalia of A. lichenshihi, the ductus bursae is wider and somewhat narrower, the corpus bursae is longer and the sclerotized area of its posterior end is wider than in A. dingjiai. Additionally, the appendix bursae of A. lichenshihi is slightly longer than in A. dingjiai and covered in more numerous but smaller spinules.
Distribution. The species is endemic to Taiwan Island.
