Oedosmylus Krüger, 1913a

(Figs 51–53)

Type species. Oedosmylus tasmaniensis Krüger, 1913a: 106 (by original designation).

Diagnosis. Female forecoxa with pedicellate setae either as larger setae in small patch, or as smaller setae more widely distributed, preapical anteroventral process absent; wings relatively narrow and ovoid, to broad and slightly falcate; FW venation dark, membrane markings variable, from mostly hyaline to mottled and darkly suffused; FW costal area relatively narrow; FW stem of RP short, RP originating close to wing base, RP1 originating close to origin of RP; RP branches strongly sinuous distally in both wings; FW end-twigging irregular and intermittent along posterior margin of wing; FW M forked midway along wing, both MA and MP pectinately to dichotomously branched; female with FW MP, CuA and/or 2A veins incrassate; CuA and CuP curved towards posterior wing margin distally; FW 2A terminating in wing margin before origin of first branch of RP; male tergites 8 and 9 entirely fused with sulcus evident; gonarcus usually with an apical acuminate prominence and densely setose, anterior apodeme of gonarcus short and narrow; entoprocessus broad and subtriangular; female sternite 8 flattened to concave, often with narrow lateral processes.

Comments. Oedosmylus is closely related to Stenosmylus and Stenolysmus, sharing a variety of wing venation and male and female genitalic characters (Kimmins, 1940; New 1990; Winterton et al., 2017). The apical acuminate process of the male gonarcus found in most species is apparently unique to Oedosmylus .
