Agapetus evansi Ross

Fig. 11

Agapetus evansi Ross, 1956: 162 .

Material examined: Paratype: New South Wales: 1 male, Ebor, BMNH [collected with holotype; both specimens were designated as paratypes of A. pontona by Mosely (in Mosely & Kimmins 1953)].

Diagnosis: In the form of the cerci and segment X, the male of this species most closely resembles that of A. stclairae , but it is distinguished by the triangular shape of the gonopods.

Forewing length: Male 5.5 mm.

Remarks: Ross (1956) distinguished A. evansi from the other Australian species on the grounds that it has a setate process basally on each gonopod. This feature is shared by A. stclairae sp. nov., with which species A. evansi also shares a set of 4 rounded papillae at about the middle of the phallic apparatus. However, the validity of assigning these 2 species to a separate species group is questionable, as in other respects, such as the angulate shape of male abdominal segment IX and the form of the phallic apparatus, they conform with A. cralus , A. dayi and other similar species.
