Cytaea dispalans is a species of jumping spider in the genus Cytaea. It is found in Myanmar, Indonesia (Borneo, Java, Lombok), and has been reported from Singapore.[1]
Taxonomy
The species was originally described by Tamerlan Thorell in 1892 as Hasarius dispalans based on a male specimen from Java.[2] It was later transferred to the genus Cytaea by Prószyński & Żabka in 1983, who removed it from nomen dubium status.[3]
In 2015, Patoleta & Trębicki conducted a comprehensive taxonomic revision and synonymized two other species with C. dispalans: Cytaea guentheri Thorell, 1895 (originally described from Myanmar) and Cytaea aeneomicans Simon, 1902 (originally described from Lombok).[4] This revision was based on examination of type specimens and detailed morphological comparisons.
Distribution
C. dispalans is distributed across Southeast Asia, with confirmed records from Myanmar, Indonesia (including the islands of Borneo, Java, and Lombok), and has been photographically documented from Singapore.[5]
Description
The original description by Thorell (1892) describes the male as having a pitch-black cephalothorax with a broad white submarginal band on the sides, formed by pubescence, and thin whitish scales showing golden or coppery coloration in the inter-ocular area. The palps are slender and black, broadly testaceous at the base. The legs are brownish-testaceous with black banding on the anterior pairs. The abdomen is ovate-lanceolate, blackish-brown above with thin bronze-green scales on the back and more golden ones on the sides. The total body length is approximately 4.2 mm.[2]
The species was redescribed in detail by Patoleta & Trębicki (2015) based on examination of multiple specimens and type material.[4]
