About Kelawakaju frenata (Simon, 1901)
Kelawakaju frenata is a medium-sized jumping spider. Males have a cephalothorax length ranging from 2.54 to 3.23 mm, while female cephalothorax length ranges from 3.14 to 3.78 mm. The dorsal lateral sides of the cephalothorax have relatively irregular bands made of dense white scales; these bands extend from behind the anterior lateral eyes to the posterior edge of the cephalothorax. On the lateral sides of the opisthosoma, there are inclined white scale bands near the posterior end. Males can be identified by their bright pedipalps, which are covered with dense white scales and long white setae, especially on the patella, tibia, and cymbium. The male palpal bulb has a distinctive embolus: it starts vertically from the basal plate, then slopes retrolaterally, with characteristic keels on the retro-ventral and pro-dorsal sides. Males have white scales on their chelicerae, while females do not. Females have a distinctive epigyne with shallow atrial rims and ellipsoid spermathecae; the spermathecae are close together medially, but separate and expand toward the distal end. This species is very similar in appearance to K. pomo, but can be told apart by several morphological features: K. frenata lacks a retro-dorsal keel on the male embolus, and has a different structure of the female atrial septum. K. frenata has been recorded from southern China, including the provinces of Guangdong, Guangxi, and Hainan, as well as Hong Kong. Specimens have been collected from multiple sites including Shenzhen, Guangzhou, and several counties in Hainan Province, and there are confirmed observations from Taiwan.
