Hoggicosa bicolor

The identity of this species was derived from a research paper by Langlands and Framenau.

The 'bicolor' species name is appropriate for this species in that some individuals, particularly adult males, may appear almost uniformaly tan in colour except of a black patch on the underside of the abdomen whereas juveniles and adult females have an abdomen and the proximal part of each leg almost completely black, only the carapace and the outer segments of the legs being a tan colour. The colour change can be quite dramatic, following a single moult.

Present evidence indicates that it is best to state that the spider shown on this page is part of the Hoggicosa bicolor group, this implying that there may be several species or subspecies that are easily confused with the specimen Roewer originally named as Hoggicosa bicolor.

Hoggicosa species seem to prefer to build their burrows in drier inland regions of Australia and some of them conserve moisture by fitting a door to their burrow.
