Evarcha bulbosa is a species of jumping spider in the genus Evarcha. It was first described by Marek Żabka in 1985 from specimens collected in Vietnam.[1] The species is distributed across several Asian countries including China, Taiwan, Thailand, and Vietnam.[2]
Distribution
E. bulbosa has been recorded from China, Taiwan, Thailand, and Vietnam.[2] The holotype was collected from Ta Pinh in the Sa Pa district of Lao Cai Province, Vietnam, at an elevation of 1,400 meters.[1]
Description
Only the male of E. bulbosa is known; the female remains undescribed.[2] The male has a distinctive appearance with a black-brown eye field bordered by a dark-orange fringe covered with white flattened hairs. The cephalothorax is brown with grey and dark brown hairs and bristles, while the front also bears white hairs.[1]
The abdomen is brown to dark grey, becoming darker towards the rear, with traces of an orange median stripe and rows of yellow and orange spots.[1] The species can be distinguished by its split tibial apophysis and the exceptionally broad bulbus of the male palpal organ, which lacks a depression on its surface.[1]
The legs show distinctive coloration, with the first pair having yellow-orange coxae and tarsi, while the remaining segments are brown. All legs, particularly the first pair, are covered with numerous white-grey and brown long hairs.[1]
