Allanagrus aurum ( Girault, 1938)

( Figs 15, 16)

Stethynium aurum Girault 1938: 388 . Type locality: Australia, Victoria, Canterbury. Stethynium aurum: Dahms 1983: 85 (type data).

Allanagrus aurum: Lin et al. 2007: 22 (generic transfer).

Type material. Holotype female ( QMBA). The holotype, the only known specimen, was not studied but a photograph was examined. Girault’s (1938) description reads “ Differs from mayeri: Cephalic scutum black; first funicle a bit shorter than the pedicel, 5 as long as 3. A female from the garden, Canterbury, Victoria, B. Blackbourn, January, 1935.” The scutum is (now) brown ( Fig. 16) but otherwise the brief description is correct.

Allanagrus aurum is extremely similar to A. mayeri . Two differences suggest that they should be kept as separate species—fore wing proportions and proportions of the clava. In A. aurum , fore wing length/width is almost 6.0 and clava length/width is 4.4 (length and width measurements taken from the holotype photograph) whereas in A. mayeri the corresponding length/width measurements are 5.4 and 3.7 (taken from the holotype specimen).
