Neozvenella paraucta Gorochov , sp.n.

Figs 12–13 , 18 , 27–29 , 47–50 .

MATERIAL EXAMINED. Holotype - ♂, Madagascar, Toamasina Prov., Moramanga Distr., ~ 10 km NW of Andasibe Vill. (18°56´S, 48°25´E), Torotorofotsy Forest Reserve , ~ 1000 m, at light, 22.II–11.III.2013, A. Gorochov ( ZIN).

DESCRIPTION. Male (holotype). Body medium-sized for this genus. Coloration: head brown with large yellowish area on dorsum between rostral apex and posterior parts of eyes (this area including all ocelli, but they almost light brown), yellowish to light brown lower part of epicranium and mouthparts, almost dark brown scape having light brown small dorsal marks, blackish pedicel, and brown to light brown antennal flagellum; pronotum brown with poorly distinct light brown marks on disc ( Fig. 12 ) and slight traces of darkish dots on lower half of each lateral lobe; pterothoracic dorsum light brown ( Fig. 13 ); pleurites and legs light brown to yellowish (femora in general barely or slightly darker than other parts of legs), with almost brown both distal part of hind femur and hind basitarsus; tegminal dorsal field light brown, semitransparent, with basal area and region of chords as well as some spots near plectrum and around mirror almost brown (but base of this basal area with distinct yellowish spot); tegminal lateral field similar to dorsal one in color but with yellowish humeral stripe and brown most part of R-M area (this area with a few small yellowish spots in distal half; Fig. 18 ); abdominal tergites and anal plate brown to light brown; all sternites and genital plate more or less yellowish; cerci light brown. External structure of body very similar to that of N. adunca sp.n. ( Figs 12–13 , 18 ); genitalia ( Figs 27, 29 , 47–50 ) most similar to those of N. aucta but distinguished by posteromedian epiphallic process with a pair of small (but distinct) lateral tubercles at base (these tubercles directed backwards and somewhat smaller than in N. adunca sp.n.; compare Figs 45 and 49 ), each posterolateral epiphallic projection with longer and more oblique ventral spine as well as smaller and less distinct (located very near previous spine) ventroapical denticle (compare Figs 49 and 53 ), ectoparamere with apical hook more similar to that of N. adunca sp.n. (i.e. longer and less strongly curved downwards than in N. aucta ) but less acute at apex (compare Figs 46, 50, 54–55 ), and rachis with clearly narrower subapical part (see Figs 47– 48 and 51–52 ); spermatophore as in Fig. 28 .

Female unknown.

Length in mm. Body 14; body with wings 21.5; pronotum 2.3; tegmina 16; hind femora 10.5.

COMPARISON. The new species is most similar and related to N. aucta ; it differs from the latter species in different body coloration (without both dark pattern on pronotal disc and dark or darkish dots on legs) and some small characters of the male genitalia listed in the description. From N. adunca sp.n. and all the other congeners, the new species is distinguished by the same genital characters as N. aucta .

ETYMOLOGY. The name of this species originates from the name of its most similar and related species ( N. aucta ) with the addition of the Latinized Greek prefix “ para- “ (near).
