Waucoris rubrus Carvalho, 1987: 161 –162, 164 (as new species: description, MG); SCHUH 1995: 972 (catalog), 2002–2013 (online catalog).

Material examined. Type specimen. Paratype Ƌ: PAPUA NEW GUINEA: MADANG: Simbai, Bismarck Range, 1900m., 29.v.1966, J. L. Gressitt leg. (FC n° 4259) ( MNRJ, ex BPBM). Additional material. 1Ƌ, 1♀: PAPUA NEW GUINEA: EASTERN HIGHLANDS: Bismarck Range, Iwam Pass, 12.v.1988, host unknown, leg. J. Van Stalle (FC n°s 3850–3851) ( ISBN).

Other species examined for comparison. Macrolygus viridulus YASUNAGA, 1992. 1♀: JAPAN: SHIKOKU: Kochi Pref(ecture), Monobe village (Kagami city), 29.viii.1993., Ex. C. harringtonia, Ali & Takai leg. (FC n° 230); 1♂: JAPAN: HONSHU: Wakayama Pref(ecture), Hatenashi (Mountain Range), 13.vi.1996, S. Gotoh leg. (FC n° 1262) ( HUES) [specimens identified by T. Yasunaga].

Diagnosis. Body elongate and wide, dark brown and red. Head black with narrow red stripes, eyes reddishbrown. Vertex finely sulcate medially, its base slightly carinate laterally. First antennal segment dark brown to black, elongate, club-like; second segment narrower, dark brown; other segments distinctly narrower than second at base. Labium reaching meso-coxae. Pronotal collar red, contrasting with head. Pronotal disk red, including areas of callosities. Femora black. Tibia and tarsus dark brown. Mesoscutum red, uncovered. Scutellum red, finely striate. Clavus red, shallowly and narrowly punctate. Endocorium and exocorium red. Cuneus red at base, dark brown medially and apically. Membrane dark brown, the veins red brown. Hemelytral pilosity short, recumbent, white.

Discussion. The genus Macrolygus was erected by Yasunaga (1992) to accommodate his new species M. viridulus from Japan (holotype: Shikoku, Ehime Pref.), the type-species by original designation described in the same paper. “ Waucoris ” rubrus Carvalho, 1987 lacks the main character of the Adelphocoris - Creontiades - Megacoelum complex of genera, of which the true Waucoris are members. Particularly, the two last antennal segment of “ W.” rubrus are narrower than the second and not almost of the same width. On the other hand, “ W.” rubrus agrees with original description of Macrolygus by Yasunaga (1992: 48-49) in virtually all major characters. Consequently, we suggest the new combination.
