COMMENT: Simplified, semidiagramatic drawings of internal structure of epigynum by Logunov in this, and related genera are insuficient to distinguish and/or compare species. Notified on my views Logunov answered (personal letter of January 28th, 2002) "... females in Bianor and related genera (and often in Pellenes; from the subgenus Pelmultus) cannot be readily separated and the female copulatory organs are of poor taxonomic value. So, no reason to compare them, as NO reliable conclusion can be drawn from observing them. " J. Proszynski

Diagnoses of genera of South East Asia: Small, squat, yellowish-brown or blackish salticids. Found at ground level at base of plants and in litter. General remarks: Species in this group are dull yellowish-brown coloured and more patterned than those in the previous group. They are often found when sifting through litter or grubbing about at the base of low vegetation in the open.
Genus: Bianor. This is a very wide but thinly spread genus. It is a small, squat salticid which is occasionally found when grubbing, and sometimes when sweeping, in grassy areas. The cephalothorax is moderately high, flat on top, with the thorax sloping steadily to the posterior margin and with very steep sides. In plan, the carapace is a broad, symmetrical oval, widest at the level of the rear eyes and has a somewhat truncated posterior margin. The abdomen is oval, not so wide as the carapace and very slightly pointed at the rear. The legs are sturdy and not particularly long, with the femora, patellae and tibiae of legs I swollen and much more robust than all the other segments. There are ventral spines on tibiae I and metatarsi I and a few more elsewhere. The colours and patterns vary. Typically the carapace is dark brown with some white hairs on the posterior and lateral surfaces. The abdomen is light brown and sometimes carries two or thee pairs of largish circular tufts of light coloured hairs. The swollen segments of legs I can be orange-brown and with thick grey-brown hairs with the other segments orange. The other legs are lighter in colour. Distribution: In our area most records for Bianor come from Myanmar, Vietnam and S. China. There has been no information since 1901 about the species, B. diversipes, from P. Malaysia. Elsewhere the relatively few Bianor species have an almost universal distribution. There are no other Bianor records for the region from P. Malaysia to Papua New Guinea. However, some records look suspicious and one gets the feeling that Bianor is likely to have a holarctic distribution. Murphy & Murphy 2000: 339.
