New synonym and descriptions of two new species of the spider genus Clubiona Latreille, 1804 from Thailand (Araneae, Clubionidae)

Abstract

The female holotype of Clubiona distincta Thorell, 1887 from Myanmar is illustrated for the first time. It is considered ajunior synonym of C. filicata Pickard-Cambridge, 1874 originally described from India. Two new species belonging tothe genus Clubiona are described from Thailand. These taxa are C. digitata sp. nov., and C. aberrans sp. nov. The con-specific female of C. filifera Dankittipakul, 2008 is designated and described. Clubiona melanothele Thorell, 1895 and C. corrugata Bösenberg & Strand, 1906 are recorded from Thailand for the first time.

Checklist of the Clubiona japonica-group spiders, with the description of a new species from China (Araneae, Clubionidae)

“…Females of C. grucollaris sp. n. are similar to C. circulata (Zhang and Yin 1998: 9, f. 4–5), C. filifera (Dankittipakul et al 2012: 57, f. 18–19, 23–24) and C. octoginta (Dankittipakul and Singtripop 2008: 39, f. 17–19, 45–46) by the broad atrium situated anteriorly, and the membranous bursae situated posteriorly, but can be recognized by the more or less inverted trapezoidal atrium with M-shaped anterior margin, and by the spiral spermathecae (Figs 13–14, 18–19). …”

“…35 (description of ♂, ♀); Gravely 1931: 261, fig. 16d; Tikader and Biswas 1981: 69, figs 120–121; Gong 1989: 109, figs 1–13; Zhang and Hu 1989: 58, figs 7, 22; Majumder and Tikader 1991: 23, figs 30–35; Biswas and Raychaudhuri 1996: 199, figs 27–33; Song et al 1999: 415, figs 245L–M, 248F–G; Dankittipakul and Singtripop 2008: 37, figs 5–7, 30–33; Dankittipakul et al 2012: 59, figs 25–31; Yin et al 2012: 1095, figs 575a–e.…”

“…In the same book, Deeleman-Reinhold (2001) carried out intensive research on this group’s limits, supplemented some characters to support the monophyly of the group, and provided a checklist of C. japonica -group species from Southeast Asia. During the past decade, at least nine species belonging to the japonica species-group were reported and described from southeast Asia, China, and India (Dankittipakul and Singtripop 2008; Jäger and Dankittipakul 2010; Dankittipakul et al 2012; Keswani and Vankhede 2014; Wu and Zhang 2014). However, a few other known species are not assigned, although they exhibit typical japonica -group features.…”

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

“…52, fig. 35 (♂♀); Dankittipakul et al 2012 : 59, figs 25–31 (♂♀); Caleb 2020 : 15719, figs 4A–F, 25G (♀).…”

“…Except for very few species, almost all of Chinese Clubiona were described or redescribed in the past 30 years ( WSC 2021 ). Clubiona from Thailand and Laos have been well studied by Deeleman-Reinhold (2001) , and Dankittipakul and co-authors ( Dankittipakul and Singtripop 2008a , b ; Dankittipakul et al 2012 ; Jäger and Dankittipakul 2010 ). Clubiona from Myanmar are relatively poorly studied; half of the described species have not been illustrated or descriptions are accompanied by inadequate illustrations ( WSC 2021 ).…”
