Bioacoustics of Xestophrys agraensis

Male ( Figures 1 & 2 ): Body large sized and stout. Fastigium of vertex ( Figures 3 & 4 ) elongate; 1.42 times as long as the diameter of eye, and its base is 1.28 as wide as eye diameter, 3 times as wide as scape; conical, straight; apex obtusely rounded. Fastigium of vertex continuous with fastigium of frons without a ventral tubercle at the base of fastigium. Median ocellus well developed. Frons weakly convex in lateral view. Pronotum (( Figure 5 ): Pronotum surface rugose; anterior dorsal margin concave, posterior margin convex; lateral carinae absent; transverse sulcus distinct; lateral lobes ( Figure 6 ) longer than high; anterior margin straight and inclined towards the lower side, posterior margin broadly rounded, lower margin almost straight; humeral sinus deep and slightly concave. Prosternum ( Figure 7 ) armed with a pair of spines; mesosternal lobes deeply bifurcated in the middle, apex triangularly rounded and curved outward; metasternal lobes triangular. Wings as long as hind tibia when straightened; tegmina slightly longer than hind wings; apex of tegmina ( Figure 14 ) obliquely rounded; stridulatory file ( Figure 15 & 17 ) slightly curved at posterior region, narrow on both anterior and posterior region, medially wide and raised, total 43 teeth; medially thick and large, short on anterior and posterior region; mirror ( Figure 16 ) of right tegmina elongate. Thoracic auditory spiracle large oval completely hidden under lateral lobe of pronotum with a medium sub apical tooth on the posterior edge of spiracle. All legs are short and thick; genicular lobes of all legs are unarmed on both sides. All femora dorsally unarmed. Fore coxae armed by well developed spine. Fore femora ventrally armed by 3 minute spines present medially to apically on inner margin; single minute spines present sub apically on outer margin. Mid femora ventrally unarmed on inner margin; 3 minute spines present medially to apically on outer margin. Hind femora ventrally armed by 3 small, thick spines arranged apically on inner margin; 9 minute to small thick spines arranged medially to apically on outer margin. Tympanum on fore tibiae bilaterally closed, elongated; the opening is directed towards dorsal side with a pair of small pits laterally just below the tympanum. fore and mid tibiae dorsally unarmed. Fore and mid tibiae ventrally armed by 6 small spines present sub basally to apically on both inner and outer margin. Hind tibiae dorsally armed by 10 small sized thick spines arranged over entire inner margin; 6 small sized spines arranged medially to apically on outer margin. Hind tibiae ventrally armed by 3 small more spaced spines arranged apically on inner margin; 5 small spines more spaced to less spaced arranged medially to apically on outer margin, single pair of dorsal spurs and two pairs (inner small and outer large) of ventral spurs present on the apical region of hind tibiae. Hind femur ( Figure 11 ) not surpassing the end of the abdomen when straightened. Tenth abdominal tergite with two triangular lobes on posterior margin and a large rounded lobe on anterior margin. Supra-anal plate ( Figure 10 ) triangular, longer than broad, projected downward. Subgenital plate ( Figure 9 ); lateral fringes well developed, posterior margin slightly concave, styli short, cylindrical and converged apically. Cerci ( Figure 8 ) thick, elongated, grooved strongly on the lateral inner side, apex incurved with a minute spine and a well developed long internal tooth curved upwardly with smooth apex, situated at the base.
