Bioacoustics of Holochlora bulbosa

Description. Habitus typical for genus; relatively large and robust in size ( Figs 13A , 14 ); head, pronotum, tegmina and legs when alive generally dark green, with head and pronotum having tint of blue, yellow when preserved ( Figs 9D, 9E , 14 ). Eyes in dorsal view globular and slightly protruding anteriorly; in frontal view slightly longer ( Figs 9E, 9F ). Frontal rostrum strongly raised, stout, with rounded apex and having median sulcus very deep ( Fig. 9E ). Antennal scapus and segments with a tint of red ( Fig. 9F ). Face and mouthparts generally light coloured, median ocellus large and pyriform ( Fig. 9F ). Pronotal disc with anterior margin straight and white ( Figs 9E ), posterior margin faintly convex ( Fig. 9E ); pronzona 1.6 times longer than metazona. Pronotal lobe 1.2 times taller than long; anterior margin white ( Fig. 14 ); ventral margin short and straight ( Fig. 9D ). Tegmen rather broad, unicolourous green ( Fig. 13A ). Fore and mid legs generally light brown; mid femur in basal half with a tint of green, middle tibia at basal third white ( Fig. 14 ). Fore tibia with inner tympanum conchate, well swollen, with narrow slit open ( Fig. 10D ); with outer tympanum large and bean-shaped ( Fig. 10E ). Hind femur green with genicular area dark brown, external lobes bispinose, margin black, dorsal spine subacute, ventral spine acute ( Fig. 10F ). Hind tibia grey with spines dark ( Fig. 14 ). Male. Left tegmen with vein 1A swollen, typical for genus, somewhat rectangular but at anal end slightly narrower ( Fig. 11C ); right tegmen with vein 1A mostly straight with basal end curved and mirror trapezoidal ( Fig. 11D ). Stridulatory file on left tegmen stout, typical for genus; straight with ca. 38 equally-spaced teeth, progressively smaller in size towards anal end ( Fig. 12B ). Abdominal apex as shown in Fig. 15 : tenth abdominal tergite forming large bulbous plate; in dorsal view trapezoidal, densely setose; laterally curved ventrad. Cercus with basal third strongly curved inward; thereafter long, slender and slightly curved; at apical end hooked, with apex tooth-like. Subgenital plate broad basally, narrowing strongly at basal third into narrow shaft with lateral margins parallel; in lateral view curved dorsad; at apical end slightly widening into two lateral lobes, roundly emarginated between lobes. Styli cylindrical, slightly shorter than apical lobes; with apices rounded. Female. Unknown. Measurements ( ♂ holotype , in mm). BL = 26.9; BWL = 58.2; PL = 6.8; PW = 4.6; TL = 47.8; TW = 10.5; HWT = 4.8; HFL = 30.1; HFW = 3.7; HTL = 32.7.
