Emended diagnosis: Inner margins of eyes with thin or no yellow band; pronotum lateral lobe yellow with rufous-brown anterior margin and blackish-brown posterior margin ( Fig. 2B ). Male. FW length varying between 6 th –9 th abdominal tergite; stridulatory file with an average number of 185±29 (n=19) teeth; harp with 4–6 veins usually (occasionally 3); mirror wider than long. Male genitalia: in dorsal view, pseudepiphallic median process longer than lateral processes and narrowing posteriorly ( Fig. 10A–C ). Female. FW length restricted to 5 th –9 th abdominal segment; ovipositor slightly shorter than body length. Copulatory papilla sclerotized to 3/4 th of its length, anterior part membranous ( Fig. 11A–B ). Emended Description: In addition to the characters of the genus: Large species. Legs. TI with a pair of ventral apical spurs, outer spur smaller than inner; one inner dorsal apical spur. TII with a pair of ventral and dorsal apical spurs, inner spurs smaller. FIII distally tapering; TIII inner ventral spur slightly longer than outer; sub-apical spurs on inner margin 5–6 and outer 6–7 (most often 6 on both sides). Basitarsomeres III with 4–5 spines on inner margin and 4–7 spines on outer. Color. Head dorsum and pronotum rufous to dark brown. Face yellow to light brown. Scape basally brown; occiput with no or faintly visible vertical yellow strips; thin yellow line, and inner margin of eyes ( Fig. 10D ). Palpi light brown ( Fig. 2C ). The area below median ocelli sometimes with a pair of brown dots. Pronotum dorsal disc same color as head; lateral lobe yellow with rufous-brown anterior and black-brown posterior margin ( Fig. 2B ). Fore and midleg yellow with brown setae. Hindleg yellow to light brown. Male. FW mostly extended to 9 th abdominal tergite, sometimes extended slightly beyond but restricted before the posterior margin of epiproct; HW length shorter than FW or very long extended beyond the abdomen. Stridulatory file with 158 to 199 teeth (mean 178, n=6); teeth on the file vein longer than wide and usually curled on either ends lengthwise ( Fig. 8A ). FW with 4–6 harp veins (rarely 3), first two veins strongly bisinuated; diagonal vein straight, chord veins regularly spaced ( Fig. 7A–C ). Mirror mostly wider than long, most often divided into two cells by a vein. Apical field long and oval on posterior margin, with five cell alignments. Lateral field with 11–15 veins. Sub genital plate longer than high in lateral view ( Fig. 2E ); supra-anal plate wider than long, apically trapezium-shaped ( Fig. 2F ). Male genitalia. Pseudepiphallus long and acute posteriorly. In lateral view, apical part pointed and bulged high in the middle ( Fig. 10B ); in dorsal view, part of pseudepiphallus as crests on either side of the median structure, the lateral crests much shorter in length ( Fig. 10A ); lateral margin of pseudepiphallus very convex; apodemes of pseudepiphallus very long, anteriorly acute and twisted from the middle of their length; pseudepiphallic parameres long. Rami straight to slightly convex on its length, with shallow bifurcation posteriorly. Ectophallic fold very long, sclerotized; either thin filament-like structure extended way beyond posterior margin of pseudepiphallus or shorter and not filament-like. Dorsal cavity long. Female. Body size either as that of male or bigger. FWs of variable length extended to 4 th to 8 th abdominal tergite; dorsal field with 11–13 diagonally parallel longitudinal veins; dorsal and lateral fields reddish-brown, the area between MA and MP yellow; lateral field with 11–15 yellow-colored veins ( Fig. 9A–B ). Ovipositor almost of the body length or slightly smaller. Female genitalia. Copulatory papilla mostly sclerotized as in Fig. 11A–B . Anteriorly conical shaped and membranous, posteriorly square-shaped and sclerotized. Remarks: It may be noted that the stridulatory file is variable in the mean number of teeth. In the population of IISERM=180±13, CC= 174±27 and KAD= 195±45. The specimens of T. mitratus observed by Lu et al. (2018) are similar in colouration and size, except for shorter ovipositor in female ( 17–19 mm against 21.1 to 24.2 mm ), which globally covers the variability of ovipositor length in the species mentioned by Townsend (1980) . The pseudepiphallus of the male genitalia of T. mitratus from Kadari often possessed an additional small bulge sub-apically that can be seen clearly in the lateral view. A similar bulge was observed by Lu et al. (2018) also in the specimens of T. mitratus . Acoustic signal: Dominant frequency of males calling song from IISERM, CC, and KAD is 3±0.2 kHz (mean ±SD); however, the number of syllables varied from 2–6 per chirp. TABLE 1a.
