description: Varitrella (Cantotrella) striata Gorochov, sp. nov.
(Figs 4, 13, 24, 39–43)
Material examined. Holotype (male): Malaysia, Sarawak State (Borneo), environs of Kuching City, Kubah National Park on Matang Mount, 200–500 m, primary forest, on leaf of small tree at night, 10–17 March 2012, A. Gorochov, M. Berezin, E. Tkatsheva, I. Kamskov (ZIN).
Paratype (male): same country and state, 80–90 km WWN of Kuching City, Gunung Gading National Park, 100–300 m, primary forst, on leaf of bush at night, 8–9 March 2012, A. Gorochov, M. Berezin, E. Tkatsheva, I. Kamskov (ZIN).
Description. Male (holotype). Size of body and coloration similar to those of V. trusmadi but with following differences: head (Fig. 4) without dark area between ocelli but with two pairs of more distinct dark brown spots on dorsum near eyes (behind lateral ocelli); pronotal disc (Fig. 4) with greyish brown wide anterior and posterior areas connected with each other by narrower greyish brown median band; most part of pronotal lateral lobes light greyish brown with numerous dark brown dots and small spots (these spots forming interrupted longitudinal stripe near dorsal edge of each lobe); tegmina with yellowish and dark spots as in V. trusmadi, with light grey (semitransparent) most part of membranes in dorsal and lateral fields, with numerous distinct light brown longitudinal stripes on membranes of mirror and of area between CuA and CuP situated before mirror, with numerous brownish grey marks on membranes of apical area in dorsal field, with additional dark brown spot near middle part of stridulatory vein, and with brown areas between chords and near mirror (Fig. 13); and anal plate with brown area somewhat larger and darker (Fig. 24). Structure of bodyparts also similar to that of V trusmadi but distinguished by somewhat wider rostral apex (scape almost 1.7 times as wide as this apex), slightly wider posterior part of pronotum (Fig. 4), clearly longer tegmina (especially apical area of their dorsal field; Fig. 13), shorter proximal and longer distal parts of epiphallus in genitalia, dorsal epiphallic spines situated near middle of epiphallus and more acute (Fig. 43) as well as with their bases more widely separated from each other (as in Fig. 39), distinctly shorter rachis (guiding rod) and ectoparameres (in comparison with V. trusmadi, widened apical part of rachis longer, and distal part of ectoparameres somewhat more strongly curved; Fig. 43), clearly shorter formula (mold of spermatophore attachment plate), and much narrower ampulla of spermatophore (as in Figs 40, 42).
Variations. Paratype (Figs 39–42) with somewhat darker longitudinal stripes on dorsum, two pairs of less distinct dark dorsal spots near eyes, and dark brown ventral surface of hind tibiae.
Female unknown.
Length in mm. Body 18–19; body with wings 29–30; pronotum 2.8–3; tegmina 20–21; hind femora 13–13.5.
Comparison. The new species is similar to V. trusmadi, V. orion, V. glabra and V. variabilis. Its differences from the first species are listed above, in the description. From V. orion, the new species is distinguished by shorter dorsal epiphallic spines, higher apical epiphallic parts in profile, distinctly shorter both rachis and distal (curved) part of ectoparameres, as well as a shorter formula in the male genitalia; from V. glabra having very similar male genitalia, by a distinctly more variegate coloration of the male dorsal tegminal field, more strongly curved distal ectoparameral parts, and higher apical parts of distolateral epiphalluic lobes; and from V. variabilis, by larger dorsal epiphallic spines, a shorter epiphallic part before these spines, a slightly concave dorsal edge of this part in profile, somewhat longer and not S-shaped (in profile) ectoparameres, and a clearly wider formula.
