Figs 3 CD, 9A, 28A–G Diagnosis . Among the species of the genus this species is very distinctive in having the head and thorax orange yellow and the crown with a prominent pair of round spots, and basal triangles of the exposed mesonotum, black. The male pygofer is about as long as wide in lateral view, with a ventral process directed posteriorly in the basal half then curved dorsally, apex not attaining the dorsal margin. Subgenital plates without macrosetae but with hair-like setae. Aedeagus with the shaft slightly compressed, apex angularly produced ventrally in lateral view, with a pair of processes arising laterally on the ventral surface, slightly shorter than the shaft. It superficially resembles Cicurbanus greeni (Melichar) in coloration but has entirely different male genitalia. Description . Orange yellow with one spot on either side of median line on crown and basal triangles on exposed mesonotum, black. Eyes dark brown. Face with one spot dorsad of antennae on ocello-ocular area, area beneath base of antennae lateral areas of frontoclypeus, dark brown; clypellus brownish. Forewing smokey transparent, veins concolorous. Thoracic tergites, sternites and legs ochraceous. Crown 0.7× as long as interocular width. Pronotum 2.0–2.2× as wide as long. Male genitalia . Pygofer about as long as wide in lateral view, with ventral process directed posteriorly in basal half then curved dorsally, apex not attaining dorsal margin. Subgenital plate more than 6× as long as wide at base, without macrosetae but with hair-like setae. Style apophysis stout, almost straight and laterally directed. Connective with arms as long as stem. Aedeagus with elongated preatrium, dorsal apodeme well-developed, shaft slightly compressed, apex angularly produced ventrally in lateral view, with pair of processes arising laterally on ventral surface, slightly shorter than aedeagal shaft; gonopore apical. Measurements . Male 4.4 mm long, 1.2 mm wide across eyes and 1.1 mm wide across posterolateral angels of pronotum. Material examined . HOLOTYPE ♂ , INDIA : U.P.

The specific epithet is the participle angulatus, a-, -um (= angulate), referring to the angulate projection of the apex of the aedeagal shaft in lateral view.
