Head, antennal segments, labial segments excluding fourth, entire pronotum, scutellum, corium and clavus, connexiva, venter of abdomen, legs except claws are dull ochraceous, with thick brown punctures; eyes brown, ocelli yellow with reddish tinge; 4 th labial segment dark; claws ochraceous brown; membrane of hemelytra brown with dark veins.

Head

Lateral margins of head slightly sinuate; paraclypei a little shorter than clypeus, tapering towards apex with apices quite acute, antennae five segmented, 1st segment not reaching apex of head, length of antennal segments, I 1.0 mm, II 2.4 mm, III 2.6 mm, 4 th and 5 th mutilated in type; labium reaching to middle of 6th abdominal segment, length of labial segments, I 2.0 mm, II 4.0 mm, III 3.4 mm, IV 3.0 mm, labial formula I <IV <III <II; bucculae distinctly shorter than basal labial segment ( Fig. 2 A).

Thorax

Pronotum more than twice as broad as long, lateral margins anteriorly dentate and posteriorly sinuate, anterior angles acute, humeral angles subacute; length of pronotum 4.0 mm, width of pronotum 8.2 mm; scutellum distinctly longer than broad at base, reaching up to 6 th abdominal sternum with apex u-shaped; length of scutellum 7.4 mm, width 6.0 mm at base, metathoracic scent gland apparatus ( Fig. 2 B) ovate with distinct well-developed, sword-shaped peritreme, a little concave on anterior margin with apex sub-acute, evaporatoria very well defined with raised outer margin; membrane of hemelytra about equal to length of abdomen.

Male genitalia

Pygophore with dorsoposterior margin ( Fig. 2 C) with shallow cavity, medial excavation and two rounded lobes on the sides of excavation, dorsolateral lobes with subround apex, ventral margin of pygophore ( Fig. 2 D) with deep cup- shaped cavity and median projection with broad apex, a little notched in center; paramere ( Fig. 2 E) L-shaped, stem without inner spine, blade broad, leafshaped, with inner spine comparatively less prominent, apical spine small and inwardly bent, inner margin of blade smooth and distinctly smooth; inflated aedeagus ( Fig. 2 F, G) with pair of very long dorsal membranous conjunctival appendages gradually tapering in width, specially apical portion very thin, somewhat sickle-shaped, posterior portion acuminated, pair of ventrolateral conjunctival appendages placed moderately apart, like shoe-hornshaped and U-shaped; pair of spatulate sclerotized penial lobes, a little longer than vesica.

Female genitalia

First gonocoxae ( Fig. 2 H) with posterior margin almost straight; 2nd gonocoxae with convex posterior margin, fused 8 thparatergite triangular with posterior margin convex but distinctly concave in middle; ninth pratergites distinctly shorter than 8th, with apices subrounded, spermathecal bulb, ( Fig. 2 I) semi sclerotized, ovate, with three finger-like processes, two small and one comparatively large.

Remarks

This new species H. naokotiensis closely related to H. hyderabadiensis sp.n. in general appearance, same colouration, paraclypei without tooth, presence of inner spine of paramere, but it differs from hyderabadiensis in having distinct bent apical spine, inner margin of paramere blade smooth and swollen, outer upper margin smoothly roundish, spermathecal bulb with three processes while in hyderabadiensis apex of paramere without spine, subrounded, upper outer margin with distinct depression, inner margin of paramere blade distinctly wavy, spermathecal bulb with two almost equal processes.
