Description.

Male holotype. Total length 5.89. Head length 1.04, width 1.03. Postocular length 0.29. Head (Figs 1-3) reddish brown, clypeus paler; with long erect and semierect setae directed dorsally; ocelli at level of imaginary line across posterior margin of eyes. Interocular space 0.55, interocellar space 0.30. Antennal lengths: scape 0.48, pedicel 0.97, basiflagellomere 0.86, distiflagellomere 1.00. Antennae light brown, with distal region of pedicel and basiflagellomere darker; distiflagellomere with a diffuse paler band basally occupying half of segment; basiflagellomere slightly clavate; with numerous short recumbent setae and sparse erect setae. Labial segment lengths: I 0.62, II 0.66, III 0.38, IV 0.40. Labium light brown with sparse erect setae, surpassing procoxae (Fig. 3).

Thorax: Collar length 0.08, anterior lobe length 0.64, posterior lobe length 0.55; anterior lobe width 1.00, posterior lobe width 1.60. Anterior pronotal lobe dark brown, posterior lobe brown with irregular paler areas, humeral angles darker; with long erect setae on both lobes. Pleurae dark brown, paler on pro- and metaepimeron (Fig. 4); with semierect and erect setae. Scutellum dark brown, with long erect setae. Hemelytron (Fig. 1) with numerous long erect setae; corial margin smooth; clavus light brown; corium irregularly pigmented with darker transverse band across middle and apical region; membrane dark with pale macula at apex, veins partially paler. Coxae, protrochanter, profemur (Fig. 5) except base and apex, distal band on meso- and metafemur, a basal short band on tibiae (diffuse on protibia), tibiae and tarsi distally and pretarsi brown, rest of legs light brown. Femora and tibiae with numerous erect and semierect setae.

Abdomen brown with paler areas on lateral margin of segments V and VI; with numerous recumbent, erect and semierect setae. Male genitalia: Pygophore (Figs 6-7) broadly rounded, anterior margin of dorsal aperture rounded, inner projections produced posteriorly. Parameres: blade relatively short, outer projection broadly rounded (Figs 8-9). Aedeagus (Fig. 10) without spines, vesica with two lobes partially sclerotized; seminal duct on vesica wide; gonoporal process broadened towards apex.

Paratypes: As holotype description, except male paratype (Figs 1-2) with distiflagellomere unicolorous; and female paratype with posterior margin of posterior pronotal lobe darker.

Measurements of male and female paratype, respectively: Total length 5.70/5.89. Head length 1.03/1.08, width 0.98/1.03. Postocular length 0.24/0.29. Interocular space 0.55/0.59, interocellar space 0.29/ 0.30. Labial segment lengths: I 0.59/0.65, II 0.66/0.67, III -/0.41, IV -/0.36. Antennal lengths: Scape 0.48/0.48, pedicel 0.92/, basiflagellomere 0.86/-, distiflagellomere 1.01/-. Collar length 0.08/0.08, anterior lobe length 0.65/0.60, posterior lobe length 0.55/0.60; anterior lobe width 1.00/1.04, posterior lobe width 1.52/1.60.

Etymology.

We are pleased to dedicate this new species to Thomas Henry in recognition of his invaluable contributions to the knowledge of Heteroptera.
