Genus Chinattus Logunov, 1999

Type species.

Habrocestoides szechwanensis Prószyński, 1992 from China.

Comments.

Chinattus is placed in the tribe Hasariini together with thirteen other genera, and is represented by 20 species mainly distributed in Asia, as well as presents the highest diversity in China ( Maddison 2015; WSC 2023). The genus is rather well studied due to all of its species having diagnostic drawings, but more than one-third of these species are known only from a single sex ( WSC 2023). To date, only two species have been recorded from Vietnam ( WSC 2023). In the present work, we place the two new species described below into Chinattus due to the similarity of habitus and copulatory organs. However, it is worth mentioning that they are also different from other Chinattus species by the absence of a basal epigynal plate and its round internal structure, and having retromarginal cheliceral fissident tooth with at least five cusps (vs. the presence of basal epigynal plate with a round internal structure and having a single retromarginal cheliceral tooth in the generotype and its congeners; see Metzner 2023), and so, the generic position of those two species may need further confirmation. Moreover, Chinattus presents very similar habitus and copulatory organs with Jajpurattus Prószyński, 1992, and the relationship between these two genera may also need further attention.
