Figs 17–18 , 115–125 .

Cestius (Cestius) indicus Sohi 1972: 131 , figs 1–9. Hishimonus indicus: Knight 1973: 153 .

Head creamy white with two pale orange red patches on crown, one on each side of midline. Pronotum yellow with four orange red patches on disc, area between patches pale yellow or whitish. Scutum and scutellum yellow, with two orange red patches at base of former. Forewings hyaline, mottled with light and dark brown, veins reddish brown. Ventral surface of thorax pale stramineous, sometimes marked with dark brown. Legs pale stramineous. Abdomen dark brown with lateral edges yellow.

Male genitalia. Pygofer longer that its height in lateral view, conically rounded posteriorly with stout setae over posterior half. Valve triangular with posterior angle more broadly rounded, 1.2 times as wide at base as long medially. Subgenital plates elongate, triangular , without membranous fingerlike process at apex, setae uniseriate, marginal in addition to short hairlike setae. Style with well developed subapical lobe, 3.5 times as long as wide at base, apophysis slightly bifid. Connective Y-shaped with stem very long, approximately 0.60 times total length. Aedeagus with shafts short, cylindrical, directed posteriorly in basal half, then dorsally, surface with numerous minute denticles, pair of long narrow processes, approximately 1.5 times length of shafts arising between bases of shafts, extending posteriorly and curving slightly dorsally, divergent from base, with dorsal marginal serration along distal half; gonopores apical.

Female genitalia. Seventh sternite 1.4 times as wide at base as long medially, posterior margin convexly rounded with small rounded median lobe. Base of first pair of valvulae gradually narrowed caudally. Second pair of valvulae with deep, irregular teeth on dorso-apical margin and with faint serrations on ventroapical margin.

Measurements. Male 3.7 mm long 1.15 mm wide across eyes.

Material examined. INDIA: Punjab: 2 ♂, 2 ♀, Ludhiana, 13.xi.1970, ex Terminalia arjuna , A.S. Sohi ( UASB).

Remarks. H. indicus was described from the holotype male and paratypes from India “Ludhiana” (Punjab). Lack of a distinct median spot on the forewing, absence of a distinct fingerlike terminal process on the male subgenital plate, the elongate stem of the connective, the bifid tip of the apophysis of the style and presence of numerous minute denticles on the aedeagal shafts are some of the characters shared by H. indicus and H. viraktamathi Knight. H. indicus can be distinguished form the latter by the shape and curvature of the basal processes of the aedeagus. This species breeds on Terminalia arjuna (Roxb.) Wight & Arn. (Combretaceae) .
