Abstract:Only one of the 130 described species of the tribe Colpurini is aposematically coloured; the others are all cryptic. The aposematic species is the largely bright red Agathyrna praecellens, which occurs in New Guinea and adjacent areas and which was, until recently, the only known species of its genus. Three brightly coloured species are placed in synonymy with praecellens: Serinetha fascicollis Walker, Astacops delineatus Walker and A. spinipes Walker. Four new, cryptically coloured species are described: Agathyrna minor from Biak Island (New Guinea), A. concolor and A. venosa from mainland New Guinea, and A. ceramica from Seram. Occasional cryptically coloured individuals of A. praecellens occur but most specimens resemble the aposematic species of the genus Astacops (Lygaeidae). It is suggested that this colpurine has only recently been recruited into the mimicry complex involving the lygaeid. The ovipositor in Agathyrna is more profoundly modified than in any other genus of the tribe, with both pairs of valvulae small and mainly membranous and the second valvifers completely absent.Only one of the 130 described species of the tribe Colpurini is aposematically coloured; the others are all cryptic.
