The species has had a complex taxonomic history and was transferred to the genus Phintella by Jerzy Prószyński in 1983.[3] Since the original holotype was incomplete, a neotype was designated by Logunov and Wesołowska in 1992 from specimens collected in the Bolshekhekhtsirskii Nature Reserve in Khabarovsk Krai, Russia.[4]
Phintella castriesiana is the largest and darkest species of Phintella found in the Russian Far East.[4] Males have a body length of approximately 4.6 mm, while females reach 4.9 mm.[5]
The male has a yellowish-brown cephalothorax with black veins and eyes surrounded by black rings. White scales are present in the vicinity of the eyes. The sternum, labium and maxillae are yellow, while the chelicerae are brownish. The opisthosoma is yellow with a dark grey pattern on the dorsal surface and light ventrally with a dark longitudinal streak. The legs are yellow with brown longitudinal stripes on the femora of legs I-III and brown dots on the proximal and distal parts of the tibiae of legs I-II.[4]
Females have similar coloration to males but are slightly paler, with all legs being uniformly yellow.[4]
