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 ).
