Bioacoustics of Ajorama chelatoides

Description. Typical of the genus, body dorso-ventrally compressed and fairly densely pubescent ( Fig. 1A ). Head dorsum pubescent. Rostrum finely pubescent, about as wide as scapus, with apex truncated ( Fig. 2A ). Face in anterior view wider than tall; with lateral ocelli posterior of scapus oval, median ocellus between scapus small circular ( Fig. 2B ). Maxillary palpi with apical segment elongated, somewhat rectangular, with heterocercal rounded apex; with subapical segment shorter and faintly expanding apically; third segment slightly longer than subapical segment ( Fig. 2C ). Pronotum transverse, wider than long; with row of setae along posterior and anterior margins; disc with anterior margin at middle feebly concave and posterior margin at middle feebly convex ( Fig. 2A ). Pronotal lateral lobe longer than tall, anterior half taller than posterior half with ventral margin rising posteriorly ( Fig. 2E ). TI with inner tympanum small and oval, but without outer tympanum ( Fig. 2F ). TIII inner and outer margins with four stout articulated spurs (also known as movable spines) on each dorsal side; and seven inner and outer basal spines, much smaller; inner margin with two long dorsal and one ventral apical spurs, outer margin with one shorter dorsal and two ventral apical spurs. Hind basitarsus with two rows of dorsal spines (each row with five spines) and three inner denticles. FW extending to eighth abdominal tergite, dorsal field slightly longer than lateral field; with five harp veins, anterior three veins converge near basal end of stridulatory file, posterior ones also converge with one another ( Fig. 2D ). Mirror area diagonally rectangular, separated by dividing vein; dividing vein broadly rounded, at middle straight; posterior part much smaller than anterior part ( Fig. 2D ). Anal area short, with apical margin diagonallyroundly obtuse. Lateral field wide, with three longitudinal veins substraight ( Figs 2D, 2E ). Hind wings reduced, reaching second abdominal tergite ( Fig. 2G ). Metanotal gland sophisticated; with anterior depression large, transverse (wider than long) and deep anterior margin strongly folded, fold at middle emarginated, along anterior fold medially with a row of strong setae; posterior fold, setose; posterior depression less wide, rounded, shallower, divided by longitudinal elevation; elevation at middle with narrow longitudinal groove ( Fig. 2G ). Tenth abdominal tergite transverse ( Fig. 2H ). Anal plate broadly triangular, at middle slightly depressed, apex subtruncated; apical margin with some stout hairs ( Fig. 2H ). Subgenital plate elongated, triangular, with apex subacute. Male genitalia as shown in Fig. 3 . Pseudepiphallus [epiphallus] deeply notched, internal margin of the notch concave; anterior part not curved upwards but protruding anteriorly. Pseudepiphallic lobe [posterolateral epiphallic lobe], in dorsal and ventral views chelated; inner margin at middle with stout triangular lobe pointing dorsad; posterior of lobe at apical third with smaller blunt lobe pointing ventrad; pseudepiphallic lobe with apical half curved, outer margins with setae very stout and strong; with apex acute and somewhat hooked. Pseudepiphallic lobe in lateral view, stout and pointing dorso-posteriorly. Pseudepiphallic posteromedial lophi [posteromedial epiphallic lobe] typical of genus; in dorsal view posterior process elongated, tongue-shaped, presented by separated sclerites directed away from each other, apex with subacute; in lateral view, with anterior (dorsal process) triangular, as tall as apical half of lophi, apex acute, faintly directed anteriorly. Ectophallic fold [rachis (= guiding rod)] elongated, not surpassing pseudepiphallic posteromedial lophi. Each ectophallic apodeme [endoparameral apodeme] forked posteriorly, and together with its long anterior apodeme forming a Y-shape structure; inner branch shorter and with truncated apex, outer branch longer (reaching bottom of epiphallic notch), and with truncated apex. Endophallic sclerite [formula (= mold of spermatophore attachment plate)] elongated; narrow anteriorly (when viewed dorsally); flattened and raised posteriorly with apex of anterior apodeme obtuse (when viewed laterally). Rami not fused together by the anterior ends, but nearly touching one another. Female. Not known. Coloration. Generally dark, red brown or brown ( Fig. 1 ). Head brown, two dark narrow longitudinal bands in the middle connecting to dark rostrum; antennae and scapus light brown ( Fig. 2A ). Gena, maxillary palpi and clypeus pale ( Figs 2B, 2C ). Pronotum dark brown ( Fig. 2A ); pronotal lobe with ventral half light brown, dark margin ( Fig. 2E ). FW red brown, some parts dark and transparent ( Fig. 2D ); lateral field with ventral part pale transparent, dorsal dark red ( Figs 2D, 2E ). Coxae pale brown, femora and tibiae yellow brown with dark and brown setae. FIII mostly light brown, but red brown near knee and with a pale band at apical third; TIII is yellow-brown, except along spines where it is dark brown; TaIII yellow brown; spines on TIII and TaIII brown with black tips. Thoracic segments, including meta- and mesosterna, except for pronotum, pale yellow brown. Abdominal tergites dark red brown, male anal plate, and subgenital plate brown ( Fig. 2H ).
