Diagnoses of genera of South East Asia: Paracyrba (8.5-8.9; 6.9-7.7). This monotypic genus was erected by Zabka & Kovac in 1996 for a spartaeine salticid with a very unusual lifestyle. So far it has been found only in the internodes of fallen bamboos with access holes which have formed naturally by decay or which have been formed artificially for study purposes. The genitalia are extremely close to those of Cyrba (see Section 51.9), and Paracyrba seems to have been separated from Cyrba mainly on the grounds of its lifestyle. Like the well known Cyrba algerina, which is usually found under a stone on its own, Paracyrba wanlessi also appears to be a "loner" with, in general, only one specimen being found in an occupied bamboo intemode. Paracyrba has a characteristic pattern. The flattish carapace is covered with blackish-brown hairs with a central, broad, transverse, whitish band with diffuse edges. On the female, this band is much whiter and much larger than on the male. The abdomen is covered with dark grey hairs with four or five transverse, diffuse, crescent-shaped, yellowish bands and a lightish area near the spinnerets. Like some other members of the Spartaeinae, the legs are long and thin which contribute to their stealthy, non-jumping movements. Distribution: Paracyrba is known only from P. Malaysia.
