( Figs 6 View FIGURES 2 – 9 , 18 View FIGURES 16 – 19 , 27 View FIGURES 20 – 31 , 63–66 View FIGURES 59 – 70 )

Material examined. Holotype (male): Malaysia, Sabah State (Borneo), Sandakan Division, environs of Sukau Vill. on Kinabatangan River (about 35 km from its mouth), almost sea level, partly primary / partly secondary forest, at light, 8–13 May 2013, A. Gorochov, M. Berezin, E. Tkatsheva ( ZIN).

Description. Male (holotype). Body slightly smaller than in previous congeners. Coloration yellowish with greyish tinge and following marks ( Figs 6 View FIGURES 2 – 9 , 18 View FIGURES 16 – 19 , 27 View FIGURES 20 – 31 ): head with light brown frons under rostral apex and under antennal cavities, dark brown both most part of eyes (upper part of eyes brown to light brown) and large central area on labrum, numerous dark dots on dorsum of epicranium, and rather numerous small darkish (light brown to brown) spots on antennal flagellum; pronotum almost light brown and with numerous dark dots on disc and lateral lobes; tegmina with light brown dorsal field having small darkish marks along medial edge from plectrum to mirror, with yellowish white humeral stripe, and with almost transparent lateral field having small brownish spots and dots along R and near this vein; legs with numerous darkish very small spots and dots on femora and tibiae, and with weakly darkened second segment of tarsi; abdomen with numerous small brownish marks on tergites, sternites, genital plate and cerci, and with slightly darkened central membrane of anal plate. External structure similar to that of previous species, but scape approximately 1.8 times as wide as rostral apex, ocelli medium-sized, pronotum similar to that of V. o r i o n ( Fig. 6 View FIGURES 2 – 9 ), tegmina with rather long apical area of dorsal field and with venation as in Fig. 18 View FIGURES 16 – 19 , hind wings somewhat longer than tegmina, anal plate with central membranous area as in Fig. 27 View FIGURES 20 – 31 . Genitalia similar to those of V. orion but distinguished by slightly shorter dorsal epiphallic spines and proximal epiphallic part (before these spines), much shorter ectoparameres with rounded (not spine-like and not curved) apical part, and distinctly wider distal part of rachis ( Figs 63–65 View FIGURES 59 – 70 ); spermatophore with almost globular ampulla ( Fig. 66 View FIGURES 59 – 70 ).

Female unknown.

Length in mm. Body 14; body with wings 22; pronotum 2.7; tegmina 16; hind femora 10.5.

Comparison. The new species is more or less similar to V. variabilis , V. trusmadi , V. orion , V. striata , V. glabra and V. robusta in the shape of epiphallus but differs from all these species in the ectoparameres of male genitalia with a rounded (not spine-like and not curved) apical part.
