Melanterius oleosus Lea, 1928: 121

This species was described from Sea Lake in northern Victoria and is also recorded from South Australia ( Lea, 1928). In the ANIC there is a specimen from Gol Gol in New South Wales (near Mildura), and we collected a single female in southern Queensland. The species is recognisable mainly by its elongate, sometimes partially confluent pronotal punctures. The body of the penis (Fig. 64) is long and narrow, with a broadly rounded apex, a pair of small apical internal sclerites and a pair of long ones at the base.

No hosts have been recorded for it, but the fact that we collected it on an Acacia conferta shrub with green pods (Table 1) suggests that its larvae may develop on the seeds of this plant species (Table 2).
