Bioacoustics of Mistshenkoana lunotan

Description. Habitus typical of the genus, medium sized, almost unicolourous cream-coloured to yellow brown ( Figs 24A, 24B ). Head with dorsum yellow brown mottled, red brown pubescent ( Fig. 24C ). Rostrum about 0.9 times as wide as scapes. Scapes yellow brown. Eyes in dorsal view distinctly protruding anteriorly ( Fig. 24C ), in lateral view about as wide as tall ( Fig. 24D ). Median ocellus oval; lateral ocelli located near eyes ( Figs 24C, 24E ). Maxillary palpi cream-coloured; with apical segment longest, somewhat rectangular to slightly tapering into subacute apex; with subapical segment slightly shorter and expanding apically; third segment about as long as subapical segment, cylindrical and slightly expanding apically ( Fig. 24D ). Face in anterior view slightly wider than tall; mostly cream-coloured except between scapes ( Fig. 24E ). Gena yellow brown ( Fig. 24D ). Pronotal disk brown with dark-brown mottled patterns, at middle longitudinally and at posterior end most prominent; 1.2 times as wide as long, barely widening posteriorly (posterior margin 1.3 times as wide as anterior margin); densely and finely pubescent, with a row of setae along posterior and anterior margins; anterior margin of disk straight; posterior margin of disk faintly convex in middle ( Fig. 24C ). Pronotal lateral lobe 1.4 times as long as high, ventrally cream-coloured, becoming brown dorsad; with a few small dark brown spots ( Fig. 24D ). Metanotal gland absent. TI swollen; with inner tympanum open and having very large elongate, oblong tympanal membrane; with outer tympanum obscure (nearly distinguishable). TIII with 5 inner and 5 outer long subapical spurs, 3 larger inner and 3 small outer apical spurs; before most proximal subapical spurs and between subapical spurs with small spines. Legs generally cream-coloured with very few irregular and sparse dark spots; FIII on dorsal parts with some dark-brown mottled patterns. TIII unicolourous cream-coloured. Thoracic and abdominal segments cream-coloured. Male. FW ( Figs 24F, 24G ) covering abdomen and surpassing apex of FIII. Colouration: cells generally yellow brown, veins brown; some cross-veins at basal half cream-coloured, at apical half with a few faint black patch around cross-veins. Along M with three small white/ cream-coloured spots: at the basal third (smallest), in the middle and near apical third (largest). Lateral field with intercalary triangle transparent, otherwise yellow brown with brown veins and cream-coloured cross-veins. Venation: without stridulatory organs, with longitudinal veins parallel; lateral field with R and M narrowly spaced apart, not parallel and with cross-veins cream-coloured; with R and Sc more widely spaced apart, more parallel and with cross-veins also cream-coloured branches of Sc generally parallel. Hind wings clearly surpassing FWs. Subgenital plate typical of genus, elongated and tapering apically; cream-coloured. Male genitalia as shown in Fig. 25 : pseudepiphallus [epiphallus] not so elongated, at middle bent inwards; at posterior end divided into two parts and angularly excised; posterior end produced into pseudepiphallic lophi [apical epiphallic lobe]. Pseudepiphallic lophi [apical epiphallic lobe], in dorsal and ventral views, long and slender and pointing posterior-externally with apex obtuse; inner margins with a few setae. In profile view, triangular with apex subacute; ventral margin with a few setae. Pseudepiphallic paramere [ectoparamere], in ventral view, elongated and slender; with anterior half (also the ventral lobe) rhombic, at middle folded, with posterior half (also the dorsal lobe) curved with apex obtuse. In profile view, ventral lobe (vl) about as broad as dorsal lobe (dl), between the lobes roundly emarginated. Ectophallic fold [rachis] small, slender and straight, taper posteriorly with apex obtuse. Female. Unknown. Measurements (in mm). BL = 10.5; BWL = 16.4; HL = 0.7; PronL = 1.0; PronW = 1.3; FWL = 11.6; FWW = 2.1; HWT = 2.5; FIIIL = 7.1; TIIIL = 8.3.
