About Evarcha bulbosa Żabka, 1985
Only the male of Evarcha bulbosa has been described; the female is still unknown. The male has a distinct appearance, with a black-brown eye field bordered by a dark-orange fringe covered in white flattened hairs. The cephalothorax is brown, with grey and dark brown hairs and bristles, and the front of the cephalothorax also has white hairs. The abdomen ranges from brown to dark grey, and grows darker toward its rear. It has faint traces of an orange median stripe, as well as rows of yellow and orange spots. This species can be distinguished by the male’s split tibial apophysis and the unusually broad bulbus of its palpal organ, which has no depression on its surface. The legs have distinct color patterns: the first pair of legs have yellow-orange coxae and tarsi, while all other segments of these legs are brown. All legs, especially the first pair, are covered in numerous long white-grey and brown hairs. Evarcha bulbosa has been recorded in China, Taiwan, Thailand, and Vietnam. Its holotype was collected from Ta Pinh, Sa Pa district, Lao Cai Province, Vietnam, at 1,400 meters elevation.
