Comments. Trochosa C. L. Koch, 1847 , with 93 species ( WSC, 2024), is a relatively large genus within Lycosidae . The majority of species in this genus (33) are known from the Afrotropical realm, with only 17 species inhabiting the Indomalayan realm. Indomalayan Trochosa are recorded from India and Nepal (6 species combined), Indonesia (5 species), southern China (3 species), the Philippines (2 species), and 1 species, Trochosa ruricoloides Schenkel, 1963 , is found throughout the entire Indomalayan realm. Until now, no species of this genus have been reported from Laos. The Indomalayan Trochosa remain poorly studied, with nearly half of the species (8) known only from one sex, primarily females. This may lead to identification challenges, as females in this genus are frequently almost indistinguishable. Almost all species from this region (14 out of 17) have been illustrated in 1–2 publications.
