Diagnoses of genera of South East Asia: Dark salticids with broad flattish carapace and long front legs. Found on shrubs and plants. General remarks: Spiders of this group are not uncommon on the leaves of garden shrubs as well as in rain forest. They attract the attention (especially of children) because the males are often seen confronting one another in a threatening manner and conducting what appears to be a sparring bout. This analogy comes about because the males hold their front legs in much the same way as two boxers approaching each other. Aided by good eyesight, this type of behaviour is not uncommon in lively, colourful salticid males and, under suitable conditions, can be induced by bringing up a mirror in front of such a salticid male. Genus: Thiania. See also Koh, p. 117. The genus Thiania appears to be restricted to the tropics in this part of the world. The species T. bhamoensis is easily and commonly seen on leaves. The cephalothorax of Thiania is flattish, rather broad, but still rather longer than broad. In plan the sides are almost straight, converging very slightly to very wide anterior and curving to a wide truncated posterior. The abdomen is elongate, rounded at the front and converging steadily to the spinnerets. Typically the cephalus is black or dark brown and followed by a broad, crescent-shaped band of iridescent, bronze-coloured, squamose hairs. The sides and the rest of the thorax are brown. The colour and pattern on the abdomen can vary. For T. bhamoensis, in the front half, there appears to be a very broad, brown chevron, bounded on both sides by narrower chevrons of iridescent, bronze coloured, squamose hairs. Legs I are slightly swollen and larger than the others. Legs I and II are brown whilst III and IV are yellow except for brown femora. Distribution: Thiania occurs from India and Sri Lanka, throughout our region and on to Papua New Guinea. Murphy & Murphy 2000: 317. By courtesy of the Authors' and the Malaysian Nature Society.
