Euporismus Tillyard, 1916

( Fig. 48 )

Type species. Euporismus albatrox Tillyard, 1916: 41 (by original designation).

Diagnosis. Female forecoxa with numerous weakly pedicellate setae arranged into irregular rows along outer ventral edge, anteroventral process absent; wings relatively broad and slightly falcate; both wings dark infuscate with stark contrasted white mottled markings and large irregular white patches apically; 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 branched; female with FW veins regular, not incrassate; FW CuA and CuP distally strongly arched towards posterior wing margin; FW 2A very short, terminates in wing margin level with origin of RP1; male tergites 8 and 9 entirely fused, ectoproct without angular process; gonarcus apex broadly truncate; entoprocesses curved and apically clubbed; female spermatheca spherical.

Comments. Euporismus is a monotypic genus from Southern Queensland with spectacularly marked wings. It is represented by very few specimens in collections; collection labels indicate that this species was found sitting on large rocks in a river bed ( Tillyard, 1916), which is unusual for a member of Stenosmylinae as species of this subfamily are typically found far from water ( Winterton et al., 2017). Certain wing characters in Euporismus are very similar to Oedosmylus and Stenosmylus , suggesting a close relationship with these genera ( Tillyard, 1916; Kimmins, 1 940).
