Genus Thelcticopis Karsch, 1884

Thelcticopis Karsch, 1884, comprising 53 species, is a medium-sized genus of Sparassidae, distributed from Korea in the Northeast and India in the West to Papua New Guinea (WSC 2024). Recently, this genus of huntsman spiders has attracted the attention of arachnologists. Several species were described from Vietnam, Laos, Philippines and the tropical part of China (Barrion & Litsinger 1995; Jäger & Praxaysombath 2009; Liu et al. 2010; Logunov & Jäger 2015; Zhu et al. 2020; Cai et al. 2021). The Hindustanian and Burmese species were revised by Sankaran et al. (2024). Despite this, Thelcticopis is still a poorly studied genus. Most of the species inhabiting islands of the Indo-Malayan realm have not been redescribed or reported since their original descriptions. Almost ¾ of the described species (39) are known only from a single sex (WSC 2024). Thelcticopis species are usually medium- to large-sized nocturnal spiders inhabiting low vegetation, tree bark, and leaf litter in forests (Cai et al. 2021; Ng et al. 2022). Some representatives of the genus, such as T. orichalcea (Simon, 1880), have a striking appearance and impressively aggressive behavior (Ng et al. 2022). Thelcticopis has a slight medical significance, as its bites are moderately dangerous to humans (Ismail et al. 2019).
