( Figures 69–73 , 76–83 )

Waucoris Carvalho, 1987: 156 (as new genus); Schuh 1995: 971 –972 (catalog), 2002–2013 (online catalog). [Type species by original designation: Waucoris keyensis ( Poppius, 1915a) ].

Diagnosis. Body length 6–8, sub-oblong, slightly convex, non-uniformly reflective yellow, orange and black ( Figs 69–73 ). Labium short, not reaching or reaching just beyond posterior coxae; first antennal segment slightly clublike, relatively elongate; vertex not carinate. Dorsal pilosity simple, recumbent, white. Pronotum of females devoid of a pair of erect stiff black setae on anterior corners, setae present in males of some species. Scutellum relatively flat. Hemelytral punctation double, one very reduced but dense, narrow and shallow, the second, shallow but larger. Metatibial spines yellowish to brown. Primary apophysis of right paramere with two pointed lobes. Endophallic structures complex, including convoluted ACH or a wrapped subapical sclerite. Comb absent. Secondary gonopore complete, devoid of pilose plate or other sclerite. Parieto-vaginal rings wide with an acute prolongation on their postero-outer margin, their latero-inner margins being very close. Ventral labiate plate always obvious, generally narrowed medially and with acute lateral corners. A pair of toothed medial process projecting into genital chamber, apparently arising from a reinforced part of the lateral roof of the chamber, partially hidden by the dorsal wall. The shape of these processes apparently species-specific. Posterior wall devoid of H-structure.

Included species. W. keyensis (Poppius, 1915) *, W. papuanus (Poppius, 1915) *, W. poppiusi Chérot & Malipatil (nomen novum, new combination)*, W. solomonensis n. sp. *, W. tricolor n. sp. *, W. wauensis Carvalho, 1987 *.

Distribution. Indonesia: Molluca Island and Papua Barat, Papua New Guinea, Solomon Islands. Host plants. Anacardiaceae, Fabaceae, Meliaceae, Rubiaceae and Ulmaceae (Chérot et al. in prep.). Discussion. The generic placement of the species W. longipes remains incertae sedis. It belongs probably to another genus and should be studied in more detail. The placement of the species A. brunnescens (Poppius, 1915) and M. rubrus ( Carvalho, 1987) , respectively in the genera Adelphocorisella Miyamoto & Yasunaga, 1993 and Macrolygus Yasunaga, 1992 (new combinations in the present work), will be analyzed more in detail in Chérot et al. (in prep.).
