Genus Ischnothyreus Simon, 1893

Remarks. Currently, Ischnothyreus includes 124 species, most of which have been recorded from tropical regions in East to Southeast Asia, and Australia ( World Spider Catalog 2023). The genus was established based on the type species I. peltifer from St. Vincent ( Simon 1893). The genus is characterized by small- or intermediate- sized scutum on the dorsum of abdomen that rarely cover the entire abdomen, dark colored and sclerotized palp, and the absence of scutum between the epigastric region and spinnerets ( Saaristo 2001; Saaristo 2010; Ono 2009; Brescovit et al. 2019).
