Contribution to the knowledge of the oribatid mite genus Angullozetes (Acari: Oribatida: Scheloribatidae)

A new species of the genus Angullozetes (Oribatida: Scheloribatidae) is described from New Zealand. Angullozetes. arilloi sp. nov. differs from the type species, A. rostratus Hammer, 1967 by the smaller body length, the presence of four pairs of notogastral porose areas and the absence of aggenital setae. A revised generic diagnosis of Angullozetes is presented. interlamellar and exobothridial setae very short, setiform. Bothridial setae clavate to globose, heads longer than stalks. Bothridia cup-like, covered completely by notogaster. Dorsosejugal porose areas present. Surface of prodorsum without heavily sculpturing and ornamentation. Notogaster . Anterior margin of notogaster not developed medially, posterior margin of notogaster rounded. Pteromorphs triangular, not movable. With three or four pairs of porose areas. Ten pairs of setae very short, setiform. Surface of notogaster without heavily sculpturing and ornamentation. Gnathosoma . Subcapitular setae setiform. Palps with setation 0–2–1– 3–9(+ω). Solenidion of palp tarsi bacilliform, attached to eupathidium. Chelicerae chelate-dentate, with two setiform setae. Lateral podosomal and epimeral regions . Humeral porose areas Ah present, Am absent. Pedotecta represented by small laminae. Custodia, discidia and circumpedal carinae present.

Among the material collected from New Zealand, we found a new species of Angullozetes. The main goals of the paper are: (a) to describe and illustrate this new species, (b) to propose a revised generic diagnosis of Angullozetes.

Material and Methods
Material. The detailed collection locality and habitat is given in the "Material examined" section.
Methods. Specimens were mounted in lactic acid on temporary cavity slides for measurement and illustration. Body length was measured in lateral view, from the tip of the rostrum to the posterior edge of the ventral plate. Notogastral width refers to the maximum width of the notogaster behind pteromorphs. Lengths of body setae were measured in lateral aspect. All body measurements are presented in micrometers. Formulas for leg setation are given in parentheses according to the sequence trochanter-femur-genu-tibiatarsus (famulus included). Formulas for leg solenidia are given in square brackets according to the sequence genu-tibia-tarsus.
Drawings were made with a camera lucida using a Leica transmission light microscope "Leica DM 2500".
Morphological terminology used in this paper follows that of F. Grandjean: see Travé and Vachon (1975) for references, Norton (1977) for leg setal nomenclature, and Norton and Behan-Pelletier (2009), for overview.
Integument ( Figure 4). Body color light yellow. Body surface densely microfoveolate, ventral side indistinctly and longitudinally striate (foveolae and stria visible only under high magnification in dissected specimens).
