Key to the genera of Clusiidae View in CoL View at ENA in Australia

1 Both mid and hind tibiae with dorsal preapical bristles. Posterior fronto-orbital bristle often smaller than anterior fronto-orbitals. Anterior fronto-orbital bristle always reclinate. Phallus sac-like .................................................. 2

—— Hind tibia never with dorsal preapical bristle; mid tibia usually without bristle. Posterior fronto-orbital never smaller than anterior fronto-orbitals. Anterior fronto-orbital bristle usually inclinate, sometimes reclinate. Phallus long and coiled or rod-like. ............................................................. 3

2 Four or five pairs of fronto-orbital bristles with third fronto-orbital from rear inclinate. Interfrontal bristle absent. Genal bristles small and hair-like, with hind bristle sometimes well developed. Head not wider than thorax. Ejaculatory apodeme enlarged distally so as to appear mushroom-shaped. Surstylus with few bristles on outer face. Spermatheca clear and untelescoped ........................................................ Craspedochaeta Czerny View in CoL

—— Two or three fronto-orbital bristles; all reclinate, with anterior and posterior bristles small to absent. Interfrontal bristle present. Several medial genal bristles more strongly developed. Head sometimes wider than thorax. Ejaculatory apodeme long and thin. Surstylus evenly setose on outer face. Spermatheca darkly pigmented and telescoped ..................................................................................... Hendelia Czerny View in CoL

3 Anterior fronto-orbital bristle reclinate. Interfrontal bristles, if present, minute and near anterior margin of frons. Occiput often very large, triangular and silvery tomentose. Spermatheca segmented, but not telescoped ....................................................................... Allometopon Kertész View in CoL

—— Anterior fronto-orbital bristle inclinate. Interfrontal bristles absent. Occiput usually narrow and shiny. Spermatheca various, but strongly telescoped if segmented ............................................................................................. 4

4 Triangular extension on outer margin of pedicel obtuse and blunt. Scutellum flat and dorsally wrinkled. One pair of thin lateral scutellar bristles. Distiphallus elongate, coiled, black, double-ribbed and fused to basiphallus. Pregonite large and fused to hypandrium. Phallapodeme highly reduced, thin and without ventral plate-like process. Postgonite absent. Lateral lobe of distiphallus absent. Ejaculatory apodeme comparable in length to hypandrium and with apex fan-like. Spermatheca strongly telescoped .................................................................................... Heteromeringia Czerny View in CoL —— Triangular extension on outer margin of pedicel acute and projecting. Scutellum smooth and slightly convex. One or two pairs of well developed lateral scutellar bristles. Phallus rod-like with components separate. Pregonite small and separate from hypandrium. Phallapodeme long, well developed and with ventral shield. Postgonite present. Lateral lobe of distiphallus usually present. Ejaculatory apodeme small with apex thin and rounded. Spermatheca untelescoped ............................................................................................................. 5

5 Mid tibia without dorsal preapical bristle. Four pairs of fronto- orbital bristles (three in some T. ustulata View in CoL ). Anterior dorsocentral bristle usually close to posterior dorsocentral. Cell bm closed. Posterior margin of male sternite 6 setose. Distiphallus curled medially and without additional anterobasal sclerite. Spermatheca irregular in shape, pigmented and strongly wrinkled ............ Tetrameringia D.K. McAlpine View in CoL

—— Mid tibia with dorsal preapical bristle. Three pairs of fronto- orbital bristles. Dorsocentral bristles widely spaced. Cell bm open. Posterior margin of male sternite 6 bare. Distiphallus straight and with small sclerite covering base. Spermatheca spherical, clear and smooth .........................................................................................
