The jumping spiders from Xishuangbanna, Yunnan, China (Araneae, Salticidae)

Abstract

Twenty one jumping spider species from South Yunnan are reported, diagnosed, described and illustrated; 19 of them are described as new: Afraflacilla ballarini Cao & Li, sp. n. (♂), Agorius tortilis Cao & Li, sp. n. (♂♀), Bavia exilis Cao & Li, sp. n. (♂), Carrhotus kevinlii Cao & Li, sp. n. (♂♀), Carrhotus sarahcrewsae Cao & Li, sp. n. (♂), Chinattus wengnanensis Cao & Li, sp. n. (♂♀), Chinophrys mengyangensis Cao & Li, sp. n. (♂♀), Cocalus menglaensis Cao & Li, sp. n. (♂♀), Cosmophasis xiaolonghaensis Cao & Li, sp. n. (♂♀), Cytaea yunnanensis Cao & Li, sp. n. (♂), Gedea pinguis Cao & Li, sp. n. (♂), Gelotia zhengi Cao & Li, sp. n. (♂), Icius bamboo Cao & Li, sp. n. (♂), Nannenus menghaiensis Cao & Li, sp. n. (♂♀), Pancorius latus Cao & Li, sp. n. (♂), Phintella lepidus Cao & Li, sp. n. (♂♀), Phintella sancha Cao & Li, sp. n. (♂), Ptocasius paraweyersi Cao & Li, sp. n. (♂♀), and Stenaelurillus fuscus Cao & Li, sp. n. (♂). Females of Bavia capistrata (C.L. Koch, 1846) and Phintella suavisoides Lei & Peng, 2013 are described for the first time. DNA barcodes of 12 species were obtained for future use.

A new genus and three new species of jumping spiders (Araneae: Salticidae) from Sri Lanka

“…nov. was provisionally placed in the genus Bavia, based on its superficially similar habitus (Cao et al 2016). However, it differs considerably from the type species of the genus Bavia, B. aericeps, by the presence of the long RTA, the broader posterior lobe of the tegulum with black blotches, the relatively longer and narrower copulatory ducts, the pear-shaped spermathecae, and the absence of a mid-posterior projection on the epigynum (very short RTA, compact and wider CD, midposterior projection in B. aericeps; see Berry et al 1997).…”

“…Prosoma oval, relatively flat, with central lighter trapezoid dorsally (Cao et al 2016) present in both sexes but more pronounced in females (Figs 1A,3A). Prosoma broader than abdomen, eye field slightly elevated, sternum oval.…”

“…Dorsum of abdomen with bright yellow or light brown markings (Figs 1A,3A). First pair of legs much darker than other pairs and more robust, with elongated femur I, patella I and tibia I. Tibia I with ventral spines in two rows of three each, metatarsi I with 2-2 ventral spines on distal half (Cao et al 2016). Embolus medium sized, straight and pointed, with or without retrolateral membranous margin, tegulum with broad posterior lobe with black blotches and well-developed prolateral lobe; RTA curved ventrally, medium-sized, slightly shorter than tibia …”

“…PEB highly sclerotized and elongated beyond epigastric furrow. (Cao, Li & Żabka, 2016) gen. et comb. nov. Cao, Li & Żabka, 2016: 54-56, figs 7-8.…”

On eight species of jumping spiders from Xishuangbanna, Yunnan, China (Araneae, Salticidae)

“…Although the genus was revised by Wanless (1984) and all species have diagnostic illustrations, six species, including the generotype, are known from only a single sex, indicating that Gelotia remains inadequately studied. To date, six species are recorded from Southeast Asia and only two, G. syringopalpis and G. zhengi Cao & Li, 2016, from China (WSC 2020. Diagnosis.…”
