Abstract
Two new stiletto fly genera of Agapophytinae (Diptera: Therevidae) are described from Australia. Sidarena gen. n. comprises six new species (Sidarena aurantia sp. n., Sidarena flavipalpa sp. n., Sidarena geraldton sp. n., Sidarena hortorum sp. n., Sidarena macfarlandi sp. n., and Sidarena yallingup sp. n.) and is largely endemic to Western Australia. Zelothrix gen. n. is described based on two species; Zelothrix warrumbungles sp. n. is a locally abundant species in Eastern Australia, while Zelothrix yeatesi sp. n. is restricted to southwestern Western Australia. These sister genera are likely closely related to Taenogerella Winterton & Irwin and Actenomeros Winterton & Irwin.
Highlights
The stiletto fly (Diptera: Therevidae) fauna of Australasia is the most species-rich biogeographical region, comprising over 400 described species in 26 genera
Two of the four subfamilies of therevidae are present in Australasia, Agapophytinae (209 species in 23 genera) and Therevinae (166 spp. in 3 gen.) (Winterton 2009, 2011; Winterton et al 2016); Xestomyzinae and Phycusinae (Gaimari et al 2013; ICZN 2015) are entirely absent from the region
We describe two new genera of agapophytine therevids from Australia, Sidarena gen. n. (Figs 1–2) and Zelothrix gen. n. (Fig. 3). Both genera were recovered as sister groups in the recent paper on therevid phylogeny by Winterton et al (2016) and appear closely related to genera such as Taenogerella Winterton & Irwin and Actenomeros Winterton & Irwin
Summary
The stiletto fly (Diptera: Therevidae) fauna of Australasia is the most species-rich biogeographical region, comprising over 400 described species in 26 genera.
