Comments. This is one of the best studied and well-illustrated Chinattus species. The male of C. validus is distinguishable from all the known Chinattus species by the widest and strongest RTA that is bent mediad ( Figs 23–25 ); the females of C. validus differ in having a unique, spoon-shaped epigynal pocket protruding from the rear edge of the epigynal plate and overhanging the epigastric furrow ( Figs 26 , 29 ) and the characteristic, S-shaped vulva ( Figs 27, 28 , 30 ). The specimens from India and Vietnam that are illustrated here correspond to and are complementary with those from China and Nepal (cf. figs 36–38 in Peng & Xie 1995: sub Habrocestoides v., and figs 1–14 in Jastrzębski & Patoleta 2014).

Hyatt, 20.VI.1954, 1♂ 2♀ ( BMNH; Fig. 27 ) .— VIETNAM: Tuyen Quang Province: c. 5 km E of Na Hang , 22°20’59”N 105°25’36”E, c. 290 m, beaten off understorey vegetation, leg. D. V. Logunov, 4–13.XI.2015, 1♀ ( MMUE, G7573.5 ; Figs 29–34 ) .

Distribution. The species is known from N India (Himachal Pradesh) (present data), throughout Nepal and Bhutan ( Jastrzębski & Patoleta 2014), to south-east China (two localities in Hunan) ( Xie et al. 1993; Peng & Xie 1995; both sub Habrocestoides v.) and northern Vietnam ( Peng & Li 2003; present data) (Map). The record from northern India lies at the north-westernmost limit of the currently known species range; it is a new species record to India and the second Chinattus species reported from there to date (cf. Basumatary et al. 2020); see also Table given below. The finding of this species from Vietnam is a new record to the country.
