Description Color yellow ( Fig. 15 ) with tinge of green or more greenish ( Fig. 16) with few or more numerous light to dark brown maculae and spots on head, pronotum, and tegmina. In living insect, abdomen with stripes of purple to red and light blue. Dark brown patch on stridulatory area of tegmina. Tenth tergite and cerci red ( Fig. 9 ). Head and antennae. Antennae filiform, of tawny color, shorter than flexed tegmina (about 33–34 mm long; N =2). Face white; eyes oval, striped. Fastigium verticis shallowly sulcate, slightly broader than width of scapus ( Fig. 6b ). Fastigium of vertex and fastigium of face meeting in deep sulcus ( Fig. 5d ). Thorax. Pronotal disc flat with dark patches near the anterior margin, often with dark to reddish fascia at lateral margins. Lateral pronotal lobes deeper than wide, ventral margin evenly rounded ( Fig. 17 ). Fore coxa with spine. Fore femora at outer margin ventrally with three dark spines, inner side unarmed, also unarmed on dorsal side ( Fig. 7b ). Fore femur slightly laterally compressed, of dark to dark purple-reddish color; short ( Fig. 17 ). Fore tibiae in area of tympanum of same patchy violet to reddish color. Ventrally with double row of each two spines, at posterior area two spurs ventrally and two spurs dorsally of the same shape as ventral spines. Tympana oval and open on both sides. Mid femora with one to two outer black spines, inner side unarmed. Ventral outer sides of hind femora with four to five tiny black spinules. Hind tibiae with four rows of numerous black spines, getting denser apically. 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 yellow-greenish color as tegmina, pointed ( Fig. 15 ). Stridulatory file (length 2.8 mm; Fig. 8c ) on the lower side of left tegmen with 68 teeth and an inter-tooth interval of 40 μm (N =1). Abdomen. Plump abdomen with blunt dorsal keel and striped pattern of transverse red and greenish broad fascia and milky white ventral side ( Fig. 17 ). This pattern fading to yellowish-tawny in preserved insect. Tenth tergite unmodified with almost straight posterior margin, cuticle smooth and shiny. Cerci short and stout, inwardly curved ( Fig. 9d ). Subgenital plate yellowish-green, broadly triangular, with posterior margin u-shaped incised, with tiny styli ( Fig. 10c ).

Figures

Fig. 15 Male P. multimaculata n. sp. among leaves of Combretum zeyheri, a savanna tree preferred by this species. Specimens are perfectly camouflaged while sitting in C. zeyheri trees. Caged specimens preferred this tree even when leaves were completely dried up and not suitable as food anymore and a rich choice of other savanna bushes and trees was available. Specimens collected from this savanna tree species were all yellowish with numerous brown to dark patches on tegmina and body
