MATERIAL EXAMINED. Holotype – ♂, Madagascar, Toamasina Prov., Moramanga Distr., Analamazaotra Forest Station near Andasibe Vill . (18°56´S, 48°25´E), ~ 900 m, at light, 1–7.III.2013, A. Gorochov, L. Anisyutkin ( ZIN) GoogleMaps . Paratypes: 8 ♂, 6 ♀, same data as for holotype, but 11.II–20.III.2013 ( ZIN) GoogleMaps ; 2 ♂, 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. Male (holotype). Body coloration: head light brown with yellowish lower half, greyish eyes, white lateral ocelli, brown transverse stripe between eyes along posterior edges of lateral ocelli, and numerous small yellowish to whitish rings on each antennal flagellum ( Figs 1–2 View Figs 1–13 ); pronotum light brown with poorly distinct darker (more or less brown) pattern on disc and numerous brown dots on lateral lobes ( Figs 2, 5 View Figs 1–13 ); meso- and metanotum as well as pleurites yellowish to whitish but with light brownish areas on lower parts of mesothoracic pleurites; legs yellowish with numerous light brown to brown dots and small spots ( Figs 2, 5 View Figs 1–13 , 15 View Figs 14–19 ); tegminal dorsal field almost uniformly greyish brown (somewhat lighter than brown transverse stripe on head) but with long and narrow whitish humeral stripe, shorter brown stripe between previous stripe and basal area, and small whitish spots at bases of MP+CuA1 branches in apical area ( Figs 14–15 View Figs 14–19 ); tegminal lateral field yellowish to whitish with greyish apical part, brown stripe along M running from base to middle of tegmen, and light brown vention ( Fig. 15 View Figs 14–19 ); abdomen light greyish brown with yellowish sternites and genital plate (except for distal part of this plate), and with light brown anal plate having almost brown subapical dorsal ridges. Structure of body parts as in generic diagnosis ( Figs 1–2, 4–5 View Figs 1–13 , 34–35 View Figs 30–55 ), but some of these parts with following possible species characters: inner tympanum moderately small, oval ( Fig. 3 View Figs 1–13 ); tegmina with stridulatory vein rather short and having rounded lateral part, with well developed plectrum, with angular shape mirror having distal half more or less cellular, with apical area of dorsal field having 7–8 longitudinal veins, with Sc having 10– 11 branches rather long and arcuate in proximal half of lateral field but shorter and more straight (barely S-shaped) in distal half of this field, and with cross venation in both fields developed but moderately sparse ( Figs 14–15 View Figs 14–19 ); genitalia ( Figs 20– 22 View Figs 20–29 , 30–33 View Figs 30–55 ) with epiphallus having narrow posteromedial processes as well as acute dorsal and rounded ventral corners of posterolateral projections ( Fig. 22 View Figs 20–29 ), and with ectoparameres having thin and elongate apical hook as well as small subapical tubercle on ventral edge ( Fig. 33 View Figs 30–55 ). Spermatophore as in Fig. 23 View Figs 20–29 .

Variations. Some male paratypes without or almost without traces of darker pattern and dots on pronotum and/or legs; their tegminal venation slightly varied (especially shape of mirror and number of cells in its cellular part); distal part of genital plate sometimes yellowish.

Female. General appearance as in males, but dorsal tegminal field with only 8–9 slightly oblique longitudinal veins and rather numerous crossveins, lateral tegminal field with 8–9 branches of Sc and moderately sparse crossveins, as well as anal plate insignificantly smaller than in male. Genital plate also short (but not small), gradually narrowing to apex, with distinct but rounded and not deep posteromedian notch, and with a pair of short rounded lobes around this notch; apical part of ovipositor as in Fig. 36 View Figs 30–55 .

Length in mm. Body: ♂ 15–15.5, ♀ 12–14; body with wings: ♂ 16–18.5, ♀ 15–17; pronotum: ♂ 2.3–2.5, ♀ 2.4– 2.5; tegmina: ♂ 11.5–13, ♀ 10–11; hind femora: ♂ 9–10, ♀ 9.5–10; ovipositor 8.2–8.8.

COMPARISON. The new species differs from the other related taxa by the characters given in the generic diagnosis.

ETYMOLOGY. This species is named in memory of the well-known entomologist and ecologist I.Kh. Sharova for her big contribution in the study of Coleoptera life forms very useful for my work on Ensifera life forms.
