Salticidae Bianor

Bianor angulosus (Karsch, 1879)

Angular Bianor

Spiders of the genus Bianor may superficially resemble Bavia or Rhene in the somewhat heavyset body, and enlarged legs I in males and females. However, they differ significantly in the configuration of their copulatory organs. Furthermore, Bianor males have a dorsal scutum on the abdomen.

In both sexes, the cephalothorax is distinctly pentagonal and somewhat flattened. While the female abdomen is adorned with a pattern of white, brown, and black hairs, the chocolate brown abdomen of the male has a lateral paired series of yellowish setae.

Length♀ 5–6 mm; ♂ 4–5 mm
DistributionSingapore, Malaysia (Sabah, Selangor), Indonesia (Java, Sumatra), Vietnam, Thailand, Sri Lanka, China, India.
HabitatFoliage in forest fringes, sometimes on reeds at wetlands, living inside a tough silken retreat.
