Tasmania currently has 27 described pompilid species in 10 genera. The bulk of these belong in Pepsinae, with Ctenocerinae (Epipompilini) and Pompilinae each represented by 6 species. Sphictostethus (Pepsinae: Pepsini) and Epipompilus (Ctenocerinae) are most speciose with 6 species each, and together they contain 8 of the 10 species only found in Tasmania. The pepsines, Calopompilus auropilosellus and Xenocurgus tasmanicus, are the two other endemics.
All wasps in this (now defunct) tribe are placed in Epipompilus. They have a rather depressed form, shorter than usual legs, head generally held more horizontal, and often eyes finely haired. Females normally with noticeably thickened fore femur and males with antennae crenulate when viewed from the side. Epipompilus species are considered primitive in their behaviour, attacking spiders in their own retreats such as under bark. Usually a female with an egg sac is located and both spider and eggs will be devoured by the larva
Both sexes in this (now defunct) tribe have the second ventral segment of the metasoma (abdomen) marked by a transverse groove or emargination. The females often have hind tibiae noticeably serrate or toothed dorsally.
