18. Nomuraius piaoacus Yin et Li, 2013 ( Figs. 3T–U)

Specimens examined. 1 female, SE slope, St. A, alt. 1,287 m, by SWA, 21. viii .; 1 male, 1 female, same as above, but st. B; 1 male, 1 female, W mine, St. B, alt. 1,622 m, by SWA, 20. viii .

Remarks. The genus Nomuraius was defined by Hlaváč (2003) with the type species, N. vietnamicus Hlaváč, 2003 described from Mt. Tam Dao, Vinh Phu Province, N Vietnam. It is distinct in the very large body with very long antennae and legs, and the posteriorly prolonged tarsomere 2 of each leg. This species was described by Yin and Li (2013) from Mt. Phia Oac.

2) The Corrected Checklist of the Pselpahine

Species known from Vietnam until 2019.

Nomura (2013) listed up 97 spp. in 66 genera of the pselaphine species known from Vietnam. However, it did not cover all known species from Vietnam. Nomura and Pham (2019) corrected the checklist with an addition of fourteen species, and the number of the Vietnamese species became 111. In these inventory works, the important papers, Kurbatov et al. (2007) and Kurbatov and Sabella (2008) were still overlooked.

Kurbatov et al. (2007) revised the taxonomy of the genus Morana and the allied genera in the supertribe Goniaceritae , the tribe Iniocyphini , the subtribe Natypleurina . Four species in 2 genera were added to the Vietnamese pselaphine fauna. Kurbatov and Sabella (2008) taxonomically revised the genus Atychodea of the tribe Tychini in the supertribe Goniaceritae . By this paper, they added two new species of Atychodea from Vietnam. As the result, 116 species in 73 genera of pselaphines have been known from Vietnam up to the present.

The asterisk used in this species list means as follows:

*: The newly added species by Nomura and Pham (2019).

**: The presently supplemented species.

***: This species was recorded as Ctenistidius coomani Jeannel, 1957 in Nomura (2013). However, the genus Ctenistidius Jeannel, 1957 was synonymized with Ctenisoschema Jeannel, 1956 in Besuchet (2008). This nomenclatural act was overlooked by Nomura (2013).
