Description Color dark green with black spot on stridulatory area. Eyes striped ( Fig. 3 ). Head and antennae. Antennae filiform, of whitish to tawny color, shorter than flexed tegmina (about 34–35 mm long; N =2). Face with white areas, eyes oval. Fastigium verticis sulcate ( Figs. 5c and 6a ), laterally slightly compressed, broader than width of scapus. Fastigium of vertex and fastigium of face meeting in deep sulcus ( Fig. 5c ). Thorax. Pronotal disc flat ( Fig. 3 ). Lateral pronotal lobes deeper than wide, ventral margin evenly rounded, anterior margin straight. Fore coxa with spine. Fore femora laterally compressed ( Fig. 7c, d ), outer margin laminate with three to five spinules, apical part with ventral furrow; inner margin unarmed. Fore tibiae purplish to reddish tinged in area of the open oval tympana ( Figs. 3 and 7d ); ventrally with double row of few spinules. Mid femora laterally compressed, with ventral furrow, unarmed. Mid tibiae shorter than mid femora. Hind femora laterally compressed, unarmed, slightly longer than hind tibiae. Hind tibiae with four rows of dense spinules. Wings. Sc and R contiguous, except near base. Tegmina elongate with oval tip. Hind wings hyaline, longer than tegmina, visible part when folded of same color as tegmina. Stridulatory file (length 2.6 mm; Fig. 8d ) on the lower side of left tegmen with 116 teeth and an inter-tooth interval of 27.5 μm (N =1). Abdomen. Plump abdomen, green. Tenth tergite unmodified, posterior margin with two broadly rounded lateral edges and slightly

(j). Arrows indicate near distally located thin C-bands (e, f), DAPI − (second panel), CMA 3 + (third panel), DAPI/CMA 3, and NOR (g, i) coincide with cluster of 18S rDNA on the first pair of autosome (marked by 1). Fluorochrome staining demonstrated DAPI+ and CMA 3 + in paracentromeric region in P. satiscaerulea n. sp. (e) whereas this region in P. multimaculata n. sp. show DAPI − and CMA 3 in most chromosomes (f); the insert in the top left corner shows a large chromosome on mitotic metaphase with C −, DAPI − /CMA 3 + heterochromatin. Arrowheads show interstitially located C-band, DAPI+, and CMA 3 + in medium-sized bivalent in both species (b, e, f). X sex chromosome depressed central part ( Fig. 9c ). Cerci stout, inwardly curved. Apical part shiny black, remaining part in most specimens green (but see Fig. 9c ). Subgenital plate broadly triangular, with posterior margin u-shaped incised, with tiny styli ( Fig. 10b ).

Female Similar to male in general shape and color pattern but without black spot on tegmen. Ovipositor well developed, up-curved with strongly serrated valves ( Fig. 11c ). Subgenital plate tri-angular ( Fig. 11d ).
