Length of body

Body size, J holotype 19.3 mm, ♀ allotype 19.4 mm

Male Genitalia

Pygophore (Fig. 2 c and d) with dorso-posterior margin with much shallow cavity, median lobe broad and excavated at middle, lateral lobe subround, ventro-posterior margin with deep cavity, median lobe broad and bifid at apex, a pair of lateral lobe broad sinuate and little tapering inward; paramere (Fig. 2 e) with very small stem, blade broad with apical margin a little produced than apical spine, inner margin much wavy like a balloon shaped, inner triangular spine prominent; aedeagus ( Fig. f and g) with highly sclerotized theca, a pair of dorsal membranous conjunctival appendages long, indistinctly lobed at apex, a pair of ventral membranous conjunctival appendages attached with dorsal membranous conjunctival appendage, a pair of highly sclerotized penial lobes, a tube like vasica shorter than penial lobes

Female genitalia

First gonocoxae (Fig. 2h) somewhat quadrate, posterior margin wavy, inner and outer angles little produced; second gonocoxae on posterior margin little concave; triangulin fully visible; eighth paratergite triangular, posterior margin convex, depressed at middle; ninth paratergite very short than eighth, apex sub round; spermathecal bulb (Fig 2i) oval shaped with four finger like processes, two of equal size comparatively thin, smaller than third, fourth thick, longer than remaining three

Material Examined

1 holotype, J: 1allotype, ♀: Miani forest , Sindh, Pakistan, leg. By A. Manan, 07-03-2005 on (Babur) Acacia arabica Wild deposited at Natural History Museum, Department of Zoology, University of Sindh . 12 Jand 2 ♀ paratype with same data deposited at Natural History Museum, Department of Zoology, University of Sindh, and Memon’s collection.

Comparative note

It is closely related to H. serrigera in general body coloration, shape of body, male pygophore with ventromedian projection broad, apical margin of paramere broad, dorsal membranous conjunctival appendages lobed at apex,. However it can easily be separated from H. serrigera by having paraclypei a little shorter than clypeus, different antennal ratio that is second and fourth antennal segment sub-equal, third longer, membrane of hemelytra longer than abdomen, peretreme sickle shaped,ventro-median lobe of pygophore bifid at apex, ventrolateral lobe relatively broad and tapering inward, paramere with apical margin a little produced than apical spine and almost straight, a little tapering to down side, inner margin swollen but wavy. In female genitalia posterior margin of the first gonocoxae wavy and inner and outer angles acutely produced, spermathecal bulb oval shaped with four, finger - like processes. While in H. serrigera second and third antennal segment sub-equal, paraclypei distinctly shorter than clypeus, membrane of hemelytra shorter than abdomen,, peretreme sword shaped, ventromedian projection of pygophore broad but not bifid, ventrolateral lobes broad and tapering out side, paramere with apical margin concave with both apices acute. In female genitalia first gonocoxae with posterior margin quite smooth, spermathecal bulb spherical with three sub-equal processes and other characters noted in description.
