Taxonomic studies on the sac spider genus Clubiona (Araneae, Clubionidae) from Xishuangbanna Rainforest, China

Abstract

Spiders of the genus Clubiona Latreille, 1804 from Xishuangbanna, Yunnan Province, China are studied. A total of 47 species is reported and illustrated, including 14 new species and two new synonyms. Twelve of the new species belong to four species groups: C. dengpao Yu & Li, sp. nov., C. subdidentata Yu & Li, sp. nov., C. tixing Yu & Li, sp. nov., C. xiaoci Yu & Li, sp. nov., C. xiaokong Yu & Li, sp. nov., C. yejiei Yu & Li, sp. nov., C. zhaoi Yu & Li, sp. nov. and C. zhigangi Yu & Li, sp. nov. from the C. corticalis group; C. mii Yu & Li, sp. nov. and C. subtongi Yu & Li, sp. nov. from the C. ternatensis group; C. banna Yu & Li, sp. nov. from the C. filicata group; and C. menglun Yu & Li, sp. nov. from the C. trivialis group. The remaining two new species, C. shuangsi Yu & Li, sp. nov. and C. wangchengi Yu & Li, sp. nov., are not readily assignable to any of the existing species groups. The female of C. cochlearis Yu & Li, 2019, the female of C. tiane Yu & Li, 2019, the female of C. bicornis Yu & Li, 2019, the male of C. lala Jäger & Dankittipakul, 2010 and the true female of C. suthepica Dankittipakul, 2008 are described for the first time. Two new synonyms are: C. vukomi Jäger & Dankittipakul, 2010 syn. nov. = C. circulata Zhang & Yin, 1998; C. melanothele Thorell, 1895 syn. nov. = Clubiona melanosticta Thorell, 1890. A checklist of Clubiona species from Xishuangbanna is provided. The DNA barcodes of almost all of the species were obtained for species delimitation, matching of sexes and future use.

Three new species of the Clubiona corticalis group (Araneae, Clubionidae) from China

“…To date, nearly one-third of Clubiona species in China belong to Clubiona corticalis species group, and more than half of them have been reported for the first time in the last five years. It is likely that this species group is not monotypic, although we follow previous studies (Mikhailov 1995;Deeleman-Reinhold 2001;Zhang et al 2021) and temporarily place these three new species in the Clubiona corticalis species group. More studies, therefore, are needed to further investigate the species diversity and morphological characteristics of this group of species.…”

Femorbiona gen. nov., a new genus of sac spiders (Araneae, Clubionidae) from Southeast Asia

“…Leg lengths are given as total length (femur, patella + tibia, metatarsus, tarsus). Terminology in the text and figure legends follows Yu et al (2017), Zhang et al (2018), Yu and Li (2019a, b), Yu (2020), andZhang et al (2021).…”

“…Clubionidae Wagner, 1887 is a relatively large family with 653 valid species distributed worldwide (Li 2020;WSC 2021). More than 80% of the species are currently assigned to the presumptively paraphyletic genus, Clubiona Latreille, 1804 (Marusik and Omelko 2018;Zhang and Yu 2020;Zhang et al 2021). Deeleman-Reinhold (2001) provided a thorough analysis of the family from Southeast Asia, with eight genera and 57 species.…”
