The jumping spider genus Pancorius Simon, 1902 is represented by 40 species primarily distributed in East, South and Southeast Asia. Amongst these, 10 (including eight endemics) are known from China.
A new species, Pancorius lui sp. nov., is diagnosed and described, based on both sexes from Yuntai Mountain in Guizhou of China. Diagnostic photos and a distribution map are provided.
East Asia, jumping spider, morphology, taxonomy
The genus Pancorius Simon, 1902, a member of the speciose subtribe Plexippina Simon, 1901, currently contains 40 large, stocky species restricted to Asia (except for P. crassipes (Karsch, 1881) which was introducted to Poland), with their highest diversity in East and South Asia (
In our recent study on the jumping spiders of Yunnan-Guizhou Plateau, a Pancorius species was recognised as new to science which is described herein.
All specimens were collected by beating shrubs and deposited in the Museum of Tongren University, China (TRU). The specimens were examined with an Olympus SZX10 stereomicroscope. After dissection, the epigyne was cleared in trypsin enzyme solution before examination and imaging. The left male palp was used for the descriptions and illustrations. Photos of the copulatory organs and habitus were taken with a Kuy Nice CCD mounted on an Olympus BX51 compound microscope. Compound focus images were generated using Helicon Focus v. 6.7.1.
All measurements are given in millimetres. Leg measurements are given as: total length (femur, patella + tibia, metatarsus, tarsus). The abbreviations used in the text and figures are as follow:
AERW anterior eye row width; AME anterior median eye; ALE anterior lateral eye; AS anterior chamber of spermatheca; CD copulatory duct; CO copulatory opening; E embolus; EF embolic flange; EFL eye field length; FD fertilisation duct; MS median septum; PERW posterior eye row width; PL posterior lobe; PLE posterior lateral eye; PS posterior chamber of spermatheca; RTA retrolateral tibial apophysis; SD sperm duct.
Male (Fig.
Pancorius lui sp. nov., female paratype and male holotype. A epigyne, ventral; B vulva, dorsal; C male habitus, dorsal; D ditto, ventral; E female habitus, dorsal; F male carapace, frontal; G male chelicera, posterior. Scale bars: A, B, G (0.2); C–F (1). Abbreviations: AS anterior chamber of spermatheca; CD copulatory duct; CO copulatory opening; FD fertilisation duct; MS median septum; PS posterior chamber of spermatheca.

The male of this new species closely resembles that of Pancorius submontanus Prószyński, 1992 from India and Japan in having similar palpal structure, but differs in the RTA, which is longer than the tibia and acutely narrowed distally in retrolateral view (Fig.
The specific epithet is a patronym, after Mr. Qianle Lu (Shenzhen, China) who helped us in collecting numerous specimens of jumping spiders; noun in genitive case.
The generic placement is due to the presence of a series of similar features with other Pancorius species, such as the band of hairs centrally on eye field, the embolic flange, the slit-shaped copulatory opening and the two-chambered spermatheca. However, this species lacks an epigynal hood and possesses a median septum, which are in contrast with what has been documented in the congeners. Therefore, the generic position of this species may need further confirmation.
