Amegilla (Asaropoda) frogatti Cockerell, 1914 Figure 13A-M

Anthophora preissi frogatti Cockerell, 1914: 468.

Specimens examined

(4 males, 3 females).

Type.

Holotype of A. frogatti : female, Brewarrina, NSW, 1914, WW Frogatt, NHM UK 010812649.

Diagnosis.

Male with round patch of black bristles on S4 and shallow emarginated apicomedial area of S5. Female paraclypeal and supraclypeal marks present, tibial scopa grey, T2 with band of black hairs anteriorly, process on S6 small narrow transverse lineo-reticulate, shiny posteriorly, not well defined (Fig. 13L ). Overall appearance grey, as in preissi .

Decision for synonymy.

Anthophora preissi frogatti was synonymised by Brooks, 1988 with preissi without stating the reason for doing so. Examination of the types of A. preissi and A. preissi frogatti clearly indicate different species, particularly because of the absence of yellow integument of the para- and supra-clypeal areas in female A. preissi . The type localities respectively, WA ( A. preissi ) and Brewarrina, NSW ( A. preissi frogatti ), may also indicate that these names belong to different species.

The description of A. preissi frogatti place it in the calva group. There is a male from the type locality: Brewarrina, NSW, 1914, WW Frogatt, in the QM collection with identification label from Hacker. The sternum morphology of this specimen shows that it is in the calva group, indicating that A. frogatti is a valid species. Although the male of A. preissi has never been described, the sternum morphology as well as the patch of bristles on S4, which has an elongated shape in A. preissi and is round in A. frogatti , also validates A. frogatti as a separate species.
