Type species: Evansiclavelia poecilopteryx Pitts, Rodriguez & Shimizu, sp. nov. (here designated).

Diagnosis

This genus differs from other genera of the Australian ‘Ctenocerini’ sensu Evans (1972) by the following female features: head wider than high ( Fig. 4a View Fig ); clypeus much narrower than LID, roughly rectangular in shape (lateral margin vertical and apical margin truncate), mostly flattened and polished; lower frons laterally to antennal sockets and below them deeply depressed with median bridge (frontal bridge) connecting frons and clypeus at the same level; eye broader than half of frons; malar space very long ( Fig. 4a View Fig ); gena in dorsal view abruptly receding posteriorly ( Fig. 4b View Fig ); and pronotum with anterior face vertical, flattened and polished, forming right angle with dorsum ( Fig. 4c View Fig ), latter truncate anteriorly, shallowly depressed anteromedially and posteriorly ( Fig. 4b View Fig ).

Description

Female

Vertex moderately convex between eye tops ( Fig. 4a View Fig ), distance from eye top to vertex crest, in profile, less than tenth of eye height ( Fig. 4c View Fig ). Posterior ocelli at level of eye tops ( Fig. 4a View Fig ). Scape curved outward with lateral face concave ( Fig. 4b View Fig ). Uppermost portion of occipital suture very high, almost at level of vertex top ( Fig. 4d View Fig , arrow).

Pronotum with shoulder swollen ( Fig. 4b View Fig ). Propodeum with declivity rather flattened but not clearly divided from dorsum ( Fig. 4c,e View Fig ).

Fore femur thinner than mid femur. Dorsal apex of fore tibia with short stout decurved spines interiorly ( Fig. 4f View Fig ) and exteriorly ( Fig. 4g View Fig ). All femora, tibiae and undersides of tarsomere 5 lacking spines. Hind tibiae without integumental serrations dorsally. Orbicula very small with a few divergent, straight, weak setae. Tarsal claws unidentate.

Transverse groove on S2 almost concealed by posterior margin of S1. S6 compressed laterally with sharp median carina.

Male

Unknown.

Distribution

Australia.

Etymology

The generic name is in honour of the late entomologist Dr H. E. Evans, who was an authority on systematics and behaviour of solitary wasps, especially of spider wasps; and ‘ Clavelia ’ a generic name in the subfamily Ctenocerinae . The name is considered feminine.
