Salticidae: Diagnostic Drawings Library

by Jerzy Proszynski 1997

Genus Chrysilla Thorell, 1887

Diagnoses of genera of South East Asia: 51.2 Square headed salticids with long thin, colourful abdomens. Found on shrubs and plants. General remarks: This section includes some of the commoner salticids likely to be seen on foliage in rain forest or garden. They are often brightly coloured and immediately attract attention. Their large, dark, anterior median eyes are noticed immediately. The long thin bodies, long legs and long chelicerae of males are characteristic. Genera for which little information is available or are possibly rare are placed here tentatively and preceded by a "?".

Genus: Chrysilla (3-4; 4-9). See Koh, p. 103. As a result of recent work, Chrysilla now has very few species, most having been transferred to Phintella (p. 352). One of the remaining species, C. lauta, has a male with the characteristic, long thin body and carapace shape of a number of rain forest salticid genera. The carapace is a fairly broad oval, longer than wide, but with a pronounced notch near the pedicel. The cephalus is flat and relatively small, with the long thorax and sides sloping away steadily to the margin. The carapace is covered in dense orange-red hairs. Straight across the front and back of the cephalus between the eyes there is a narrow band of shiny bluish-white, iridescent hairs. There is a narrow band of similar hairs along the margin. Although the chelicerae are robust and diverge, they do not project forward. The abdomen is long, narrow and tubular, rounded anteriorly and tapering very gradually to a bluntish posterior. There is a long scutum which, except near the shoulders and near the spinnerets, entirely covers the dorsal side of the abdomen. It is dark brown in colour and covered with dense, bronze coloured hairs. The legs are long, slender and, except for the ventral spines on the tibiae and metatarsi of leg I, are not particularly spiny. Save for legs I and metatarsi IV which are brown, the remaining segments are uniformly brownish-yellow.
Distribution: Chrysilla is known from India, Myanmar, Vietnam, China, P. Malaysia, Singapore, Sumatra and Australia. Murphy & Murphy 2000: 298. By courtesy of the Authors' and the Malaysian Nature Society.
