Diagnosis

Head shiny, contrasting with a dull pronotum and hemelytra. Pronotum and scutellum without erect setae. Distiflagellomere and hemelytra uniformly coloured cinnamon brown. Profemora pale yellowish brown.

Heraeus cinnamomeus and H. costalis sp. nov. are the only two species of the coquilletti group that have a shiny head, contrasting with a dull pronotum and hemelytra, and the scutellum lacking erect setae. The general colouration of H. cinnamomeus is cinnamon brown, with distiflagellomeres and hemelytra uniformly coloured, whereas H. costalis sp. nov. is dark brown with the distiflagellomere mostly white and with the apex darker.

Redescription ( Fig. 3A )

Paratype ♂

Head: Strongly convex dorsally ( Fig. 4A ). Colour orange brown, shiny and smooth, with short recumbent and erect setae dorsally. Eyes slightly protrud- ing, not surpassing the dorsal margin of head in lateral view. Ocelli posterior to an imaginary line passing the posterior border of eyes. Labium pale brown with erect setae, extending to mesocoxae. Antennae pale brown, distiflagellomere slightly paler; with short recumbent, semi-erect, and erect setae.

Thorax: Pronotum dull brown, anterior lobe darker; pruinose, punctate ( Fig. 4B ); collar punctate, delimit- ed posteriorly by a sulcus and a row of punctures, anterior pronotal lobe with punctures more conspicuous posteriorly, posterior pronotal lobe coarsely punctate; anterior and posterior lobes with minute setae. Pleurae brown. Evaporative area short. Scutellum brown, pruinose ( Fig. 4C ), punctate, with minute recumbent setae. Hemelytra pale brown, pruinose ( Fig. 4C ), with minute recumbent setae. Corium with a diffuse subapical pale spot; lateral margins slightly concave. Membrane pale brown, veins concolorous. Legs pale brown, coxae and apical third of metafemur, and apex of tibiae, darker ( Fig. 5A ); with sparse, short, recumbent and erect setae. Tibiae with spiniform setae. Profemur conspicuously incrassate in males; spines on profemur small, except for one much larger spine. Protibia with small tubercles bearing spiniform setae in a row along inner surface.

Abdomen: Brown, with abundant short recumbent setae. Male genitalia: Pygophore ( Fig. 6A, B ) rounded, anterior margin of dorsal aperture slightly rounded, inner projections projecting posteriorly. Parameres: Figure 6 (C, D). Aedeagus: Conjunctiva unspined, vesica with small spines, lobes of vesica strongly sclerotized at base; processus gonopori long and slender.
