The holotype and paratype were deposited in Natural History Museum, Karachi, Sindh Pakistan ( NHMUK) and remaining material is kept in Memon’s collection .

Size Holotype: ♂ 19.0 mm; Allotype ♀ 19.9 Paratype: ♂, (19-19.3), ♀ (19.9-20.0)

Colour Head pronotum, scutellum, is dull ochraceous, thickly and densely punctured with dark brown tinge; eyes dark brown with outer border dull ochraceous; ocelli pale ochraceous; antennae brown; pronotum and scutellum streaked with dark and light stripes; apex of scutellum light brown, with few dark brown puncture; each segment of abdomen dark brown with middle portion light brown; membrane of hemelytra bright brown with dark veins; labium ochraceous except a little basal portion of 3 rd and entire 4 th segment are brown; legs ochraceous brown with dark patches.

Head Head distinctly longer than broad, tapering upward; Paraclypei almost equal to clypeus, lateral margins almost smooth and without tooth; anteocular region of head twice more than remainder of head, antennae five segmented, 1 st antennal segment not reaching apex of head, anteocular distance 3.4 mm, remainder of head 1.4 mm long, width of head 3.3 mm, interocellar distance 1.1 mm; interocular distnace 1.9 mm, length of head 3.0 mm, antenniferous tubercles partially visible, length of antennal segments: I 0.9 mm, II 2.0 mm, III 1.5 mm, 4th and 5th mutilated in holotype ♂ and paratype ♀, among three segments, 2 nd is longest and 3rd is smallest segment; labium extending to fourth abdominal sternite, length of labial segments: I 2.1 mm, II 4.0 mm, III 3.4 mm, IV 2.8 mm ( Fig 1 A).

Thorax

Pronotum twice as broad as long, and distinctly shorter in length than head length, lateral margins of pronotum anteriorly dentate, posteriorly a little sinuate, humeral angles quite subacute; length of pronotum 3.9 mm, width 8.0 mm; scutellum distinctly longer than broad at base, reaching to three-fourth of abdomen, apical lobe U-shape, length of scutellum 6.8 mm, width 4.9 mm, metathoracic scent gland complex ( Fig. 1 B) with small ovate aperture, peritreme well-developed, sword-shaped with apex subacute and facing upward, evaporatoria large and very well-defined; membrane of hemelytra equal to abdomen.

Abdomen

Connexiva well exposed, joints sub-acute.

Male genitalia

Pygophore quadrate, dorsoposterior margin ( Fig. 1 C) with deep cavity, to some extent V-shaped, laterally sinuate and medially excavated, ventroposterior margin ( Fig. 1 D) with shallow cavity, laterally smooth and with apically bifid median projection, lateral lobes broad; paramere ( Fig. 1 E) with small stem, blade broad, ovalshaped, inner margin distinctly wavy, apex without spine and sub-round, outer upper margin near apex depressed distinctly, inner triangular spine present; inflated aedeagus ( Fig. 1 F) with pair of long and apically lobed dorsal membranous conjunctival appendages, pair of ventrolateral membranous conjunctival appendages, pair of highly sclerotized comparatively thin apically subround penial lobes, tube-like vesica very much shorter than penial lobes.

Female genitalia

First gonocoxae ( Fig. 1 G) somewhat quadrate, inner margin concave, posterior margin concave near inner angle, inner angle distinctly produced; second gonocoxae on posterior margin a little concave; eighth paratergite triangular with posterior margin convex; ninth paratergite very short than eighth paratergite with apex sub-round; triangulin fully visible; spermathecal bulb ( Fig. 1 H) quite round with two almost equal finger-like processes.

Remarks

This new species H. hyderabadiensis is closely related to two species H. shaista Ghauri and H. naokotiensis sp. n in having paraclypei without tooth and, shape of blade which is broad, ventral margin of pygophore with broad and medially a little notched median lobe, but it is very much different in having 2 ndantennal segment distinctly longer than 3rd, blade with round apex and without apical spine, inner spine much prominent, outer margin at apex depressed, inner margin very much sinuated, first gonocoxae with outer margin concave and with distinctly produced inner angle, spermathecal bulb with two finger-like processes while in naokotiensis 2 nd antennal segment sub equal or a little longer than 3 rd, parameral blade with bent spine, inner spine less prominent, inner margin swollen, first gonocoxae posteriorly quite straight and spermathecal bulb with three processes.
