A female from Bulburin State Forest, Queensland (Figs. 9A–E) is here tentatively identified as A. melanura pending a comprehensive revision of this apparent widespread species that has been reported from India throughout China to Japan and into Indonesia ( World Spider Catalog 2019 ). It is clearly not an A. higginsii specimen based on somatic characters, i.e. shape of the abdominal tail, and genital morphology (Figs. 9A–E). The epigynum (Fig. 9E) matches well the illustration by Chrysanthus (1961) who firstly reviewed this species; however, the tailend of the Australian specimens is more swollen and the protuberance less conspicuous than depicted by Chrysanthus (1961) . Descriptions and illustrations of A. melanura in the scientific literature vary and it is possible that this taxon as currently understood represents a cluster of species. Apparently, no author redescribing this species after Simon’s (1867) original description studied the type material. All relied solely on the original verbal description of the species or subsequent taxonomic studies. It is clear that A. melanura requires thorough revision which is beyond the scope of this study for a species with a single, likely incidental record in Australia .
