Himalisundacoris takaii , new species

( Figs. 11E, F , 15 I−K, 31A–G)

Type material. Holotype: male, INDONESIA: South Sulawesi, Lompobattan , 30 miles E of Makassar (Ujung Pandang), 5°19′S, 119°56′E, M. Takai, 22–25 December 1999 ( ZRC) ( AMNH _ PBI 00378786 ).

Diagnosis. This new species is currently known only by a single male specimen and distinguished from other congeners by the uniformly dark brown antennomere II, and darkened lateral parts of pronotum, entire thoracic pleura, clavus and abdomen ( Fig. 11E, F ).

Description. Male: Body oval, slightly elongate; basic colouration pale olive brown with widely darkened pronotum, scutellum, clavus and ventral surface ( Fig. 11E, F ); dorsum polished, oily shiny. Head pale reddish brown, smooth; vertex with narrow, weak basal transverse carina that is interrupted mesally ( Fig. 31A ); clypeus and lorum entirely shiny fuscous. Antenna dark brown; antennomere I partly pale mesially; antennomere II uniformly darkened; extreme base of antennomere III creamy yellow. Labium pale brown, reaching but not exceeding apex of metacoxa; apical 2/3 of segment IV darkened. Pronotum pale olive brown, darkened laterally, almost glabrous; pleura uniformly dark brown; metathoracic scent efferent system pale brown; scutellum pale olive brown, with a pair of dark, triangular maculae. Hemelytron oily shiny, with uniformly distributed, pale, simple, reclining setae ( Fig. 31A ); whole clavus and apical half of corium dark brown; cuneus yellowish brown, with darkened extreme apex; membrane pale greyish brown, semi-transparent, with slightly darker veins. All coxae reddish brown; legs pale brown; metafemur with reddish basal half and two subapical brown rings; each tarsomere III slightly darkened; meta-tarsomere II as long as III; parempodia rather short ( Fig. 31C ). Abdomen uniformly shiny dark brown. Male genitalia ( Figs. 15 I−K, 31D–G): Hypophysis of left paramere inflated, elongate, with anchor-shaped apex ( Fig. 31E ); right paramere bulbous, short, with small hypophysis ( Figs. 15K , 31F ); notches of vesical lobal-sclerites rather small ( Figs. 15I , 31G ). Female: Unknown.

Measurements. See Table 1.

Etymology. Named after Mr. Mikio Takai, who collected and provided numerous Asian specimens of the Miridae ; a noun in the genitive case.
