Formosargus James 1939

Genus Formosargus James, 1939 Fig. 4 Formosargus James, 1939: 35. Type species Formosargus kerteszi James, 1939 [DEI], by monotypy. See Woodley (2001: 190) for full list of synonymy. Diagnosis. Small (length 5–7 mm), yellowish brown species, similar to Ptecticus, but distinguished by the: frons wide and almost parallel in females; face slightly anteroventrally produced to form a small beak-like protuberance that is visible in profile; scutum with a distinct black medial stripe; wings with vein M 1 and M 3 extremely weak and nearly unpigmented between cells br and bm; M 1 and M 3 very weakly developed; M 4 issued from discal cell (i.e. dM 3+4 absent); alula reduced, almost linear; and lower calypter linear, without projecting process. Remarks. Regarding the New Guinean fauna, Chrysochlora lineata de Meijere, 1913, is congeneric with Formosargus, sharing the characters noted above in the diagnosis. Therefore, we propose moving the species into the latter genus, to become Formosargus lineata (de Meijere, 1913) new combination. Distribution. Northern Queensland, new distribution record (Fig. 2).
