Portia orientalis is a species of jumping spider in the genus Portia . It has only been found in Hong Kong. [1] Only the male has been described. [2]
Portia orientalis was first described in 1983 by John Murphy and Frances Murphy based on a single male specimen from Hong Kong. [2] The species is closely related to Portia assamensis and Portia labiata , but can be distinguished by differences in the male palp structure, particularly the shape of the embolus and palpal tibia. [2]
P. orientalis is known only from Hong Kong where the holotype was collected. [1] [2] The species is known only from the type specimen. [2]
The male holotype measures 7.6 mm in total length, with a carapace length of 3.4 mm. [2] The carapace is orange-brown in color, lighter in the eye region, and covered with light orange hairs. A distinctive feature is the presence of pronounced orange tufts of hair near the posterior lateral eyes, which distinguishes it from related species P. assamensis and P. labiata. [2] The carapace has a parallel white band running from the fovea to the posterior margin and broad white lateral bands along the margins. [2]
The chelicerae are parallel and orange-brown with dark longitudinal marks, bearing three teeth on each margin. [2] The legs are uniformly dark orange in color, with the metatarsi and tarsi being somewhat lighter. Unlike related species, the femora III and IV lack annulations. [2]
The male palp shows several distinguishing features. The central finger-like apophysis on the ventral side of the palpal tibia is very pale, small, and hidden within a tuft of long white hairs. [2] The embolus narrows gradually from its basal section, which differs from the narrow embolus of P. assamensis and the suddenly narrowing embolus of P. labiata. [2]
