Figs. 5C, D , 9B , 12B , 13G–I , 15C , 18A–H

Diagnosis. Coloration similar to that in H. borneensis Schmidt , but crown disc dark brown to black, basal triangles of mesonotum pale brown. Male pygofer ventral process bifurcate. Style apophysis with mesal margin convex. Aedeagus with length of atrium and shaft subequal (see Remarks also).

Description. Pale brown with dark brown markings on face, crown, pronotum and mesonotum. Vestiture with black, brown and gray hairs. Crown dark brown with anterior marginal ridge pale brown. Eyes dark brown with reddish tinge. Face with frontoclypeus, clypellus, lora, black; lateral oblique narrow stripes on frontoclypeus and genae, creamy white to pale brown. Labium pale brown. Pronotum anterolateral marginal areas pale brown, gibbous area dark brown to black especially in anterior region. Mesonotum basal triangles pale brown, median and posterior regions of mesoscutum black, hump dark brown to black, posterior face of hump and flattish portion of mesoscutellum creamy white with apex and lateral margins reddish brown. Forewing hyaline with brownish venation. Legs and abdominal sterna pale brown, meta tarsi darker, bases of macrosetae on meta thoracic leg dark brown Abdominal pleurite III and tergite IV entirely and a spot on either side of median line on tergites V with bright yellow spots, ( Fig. 12B ), rest dark brown ( Fig. 12B ). Exposed abdominal tergites and anal tube orange pale brown, anal style compressed and bright reddish brown.

Crown about 0.8× as long as interocular distance. Pronotum about as long medially as wide anteriorly behind eyes, and almost 2× as wide at posterolateral angles. Mesonotum 1.8× as long as pronotum medially.

Male genitalia. Pygofer 2.7× as long as height in lateral view, posterior margin oblique and concave; ventral process forked at about midlength, each fork tapering distally, dorsal fork shorter than ventral, forks widely separated at base. Subgenital plate widest at midlength, about half as wide at midlength as long. Style apophysis with mesal margin convex, outer margin sinuate, apex narrowed. Aedeagus with shaft about as long as atrium, shaft widest at about midlength both in lateral and posterior view, gonopore apical to subapical on ventral surface.

Measurements. Male 11.4 mm long, 2.3 mm wide across eyes and 3.4 mm wide across posterolateral angles of pronotum.

Material examined. HOLOTYPE ♁, INDIA: Manipur: Ukhrul , 1647 mts, 25006.485 ’N 94021.022 ’E, 28.viii.2014, Sweep net, Yeshwanth, H.M ( UASB).

Etymology. The species being the first record of the genus from India, is named after the country where it lives.

Remarks. This species closely resembles the type species from Borneo ( Malaysia) but differs in the following characters: a) crown with disc dark brown (crown disc with median pale brown stripe in H. borneensis ); b) mesonotum with basal triangles pale brown (entire mesoscutum dark brown in H. borneensis ); c) entire tergite IV bright yellow with a median brown stripe (dark brown with one bright yellow spot on either side of median line in H. borneensis ); d) male pygofer ventral process forked (not forked in H. borneensis ); e) style apophysis mesal margin convex (concave in H. borneensis ) and f) aedeagus with shaft about as long as atrium in lateral view (much longer than atrium in H. borneensis ).
