Diagnosis. Recognised by fuscous chestnut brown basic colouration; creamy yellow clypeus, pro- and mesofemora, pro- and mesotibia, and abdominal sternites IV−VI, in addition to the characters mentioned in generic diagnosis.

Description. COLOURATION: Body chocolate brown to fuscous ( Fig. 1 View Fig A−C). Head blackish brown, with creamy clypeus ( Fig. 1B View Fig ); vertex about as wide as an eye in dorsal view, with a faint, narrow, longitudinal, mesal sulcus; frons shallowly and obliquely striolate. Antenna uniformly yellow dorsally, dark ventrally; segment II about as long as metafemur; segment III about as long as labium. Labium shiny dark brown, slightly suffused with red ( Fig. 1B, C View Fig ). Pronotum uniformly dark, smooth; pleura widely darkened, rather shining, with creamy yellow ostiolar peritreme ( Fig. 1B View Fig ); scutellum nearly flat, transversely rugose medially. Hemelytron concolorously fuscous; apical inner part of cuneus slightly tinged with red; membrane smoky brown. All coxae dark brown, except for apical part of metacoxa creamy yellow; trochanters and legs creamy yellow; metafemur chocolate brown, except for pale extreme base and apex; metatibia smoky brown; all tarsi pale brown. Abdomen fuscous; sternites IV−VI pale brown or creamy brown ( Fig. 1B, C View Fig ). Surface, vestiture, and structure as in generic description.

Measurements. See Table 1.

Etymology. From Latin, niger (= black) combined with tenuis (= slender), referring to the darkened, slender body of this new species; an adjective.

Distribution. Brunei, Indonesia (northern Sulawesi and northwestern highlands of Sumatra), Malaysia, Thailand, and Vietnam ( Fig. 12 View Fig ).

Biology. All available specimens collected using UV light traps were found to be covered partly with pollen (cf. Fig. 2K View Fig ). This mirid is assumed to inhabit inflorescence of (most probably broadleaf) angiosperms and appears to be a pollinator in the Asian tropical forest-zone ecosystem (cf. Fig. 1D View Fig ). Collection records suggest that this mirid has at least two generations per year.
