Bioacoustics of Mistshenkoana higaonon

Description. Habitus typical of the genus, medium sized, cream-coloured to yellow brown with dark-brown mottled patterns ( Figs 26A, 26B ). Head with dorsum dark brown mottled, pubescent. Rostrum finely pubescent, dark coloured, about 0.9 times as wide as scapes ( Fig. 26A ). Scapes yellow brown with brown patterns. Eyes view distinctly taller than long ( Fig. 26C ). Median ocellus oval; lateral ocelli located near eyes. Maxillary palpi cream-coloured; with apical segment longest, dorso-posteriorly dark-coloured, flattened and somewhat rectangular, with obliquely-truncated apex; with subapical segment shorter and faintly expanding apically; third segment longer than subapical segment, cylindrical and slightly expanding apically ( Fig. 26D ). Face in anterior view as tall as wide; mostly cream-coloured except between scapes ( Fig. 26E ). Gena cream-coloured, posterior of eye with two dark brown bands ( Fig. 26C ). Pronotal disk brown with dense dark-brown mottled patterns; 1.4 times as wide as long, widening posteriorly (posterior margin 1.6 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 broadly convex in middle ( Fig. 26A ). Pronotal lateral lobe 1.2 times as long as high, cream-coloured with some dark-brown mottled patterns ( Fig. 26C ). 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 4 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 irregular and sparse dark spots; Fs with more dark spots in the apical half; Ts generally with more dark spots. FIII with a dark brown mottled patterns on inner and outer parts; in dorsal view with three oblique bands, apical band thickest, followed by basal and middle bands. TIII in dorsal view with dark patches and spots. TaIII basal segment cream-coloured with basal and apical parts dark coloured. Thoracic and abdominal segments cream-coloured; abdominal tergite with some dark colouration. Male. FW ( Figs 26F, 26G ) covering abdomen and surpassing apex of FIII. Colouration: cells generally yellow brown, veins brown; cross-veins at basal half typically cream-coloured, at apical half with faint black patch around cross-veins. Along M with three elongated white/ cream-coloured spots: at the basal third (smallest), in the middle (largest) and near apical third. Lateral field with intercalary triangle transparent, otherwise yellow brown with brown veins and cream-coloured cross-veins ( Fig. 26G ). Venation: without stridulatory organs, with longitudinal veins parallel; lateral field with R and M narrowly spaced apart, mostly parallel and with cross-veins cream-coloured; with R and Sc spaced apart, parallel and with cross-veins (especially in the basal half); branches of Sc generally parallel. Hind wings clearly surpassing FWs ( Figs 26A, 26B ). Subgenital plate typical of genus, elongated and tapering apically; cream-coloured. Male genitalia as shown in Fig. 27 : pseudepiphallus [epiphallus] not so elongated, tapering slightly posteriorly; at posterior end divided into two parts and roundly and very narrowly 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, dorsal margin somewhat straight throughout, ventral margin at middle bent; basal half tapering more than apical half; apical half slender triangular; 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) with rounded apex and a small spine-like process at the inner-apical part. In profile view, ventral lobe (vl) broader than dorsal lobe (dl), between the lobes rounded emarginated. Ectophallic fold [rachis] small, slender and straight, taper posteriorly with apex obtuse.
