Neozvenella aucta Gorochov, 2004

Figs 19 , 51–55 .

MATERIAL EXAMINED. Madagascar: 13 ♂, 1 ♀, Toamasina Prov., Moramanga Distr., Analamazaotra Forest Station near Andasibe Vill . (18°56´S, 48°25´E), ~ 900 m, at light, 1–20.III.2013, A. Gorochov, L. Anisyutkin ( ZIN); 1♂, same province and district, ~ 10 km NW of Andasibe Vill., Torotorofotsy Forest Reserve , ~ 1000 m, at light, 22.II–11.III.2013, A. Gorochov ( ZIN) .

DESCRIPTION. Female (nov.). General appearance similar to that of male holotype [ Gorochov, 2004] but with following characteristic features: coloration yellowish with a pair of light brown longitudinal bands on posterior half of head dorsum, brown edges of antennal cavities, brown to light brown marks on scape, numerous small light brown spots on antennal flagellum, brown median band on pronotal disc and a pair of large dots around this band, very sparse darkish dots on upper half of head and on lateral tegminal fields, numerous dark and darkish dots on lateral pronotal lobes and on legs (some of threse dots large and sometimes looking as small dark spots on fore and middle tibiae), row of frequent small light brown spots between R and M in each tegmen, and similar but sparser and irregularly situated spots and dots on dorsal tegminal field; external structure of body similar also to that of male of N. adunca sp.n. but distinguished by somewhat smaller inner tympanum, dense and almost completely cellular venation of dorsal tegminal field (in this venation, traces of 6–7 obliquely transverse branches poorly visible only), lateral tegminal field with normal longitudinal veins (including 11–12 oblique branches of Sc) and more or less cellular crossvenation between them; genital plate trapezoidal with widely rounded posterolateral corners and barely concave posterior edge; ovipositor more or less similar to that of Ocellotrella gen. n.

Length in mm (♀). Body 12; body with wings 22; pronotum 2.2; tegmina 15.5; hind femora 10; ovipositor 8.

REMARKS. The males examined are similar to each other and to the holotype of N. aucta in general appearance and structure of the male genitalia (this species was described also from “Analamazaotra” [ Gorochov, 2004]). However, they are somewhat variable in coloration and shape of some male genital structures, but a dark pattern on the head and pronotum as well as numerous darkened dots on these structures and on legs are developed practically always.
