Liphistius hpruso Aung et al., 2019: 32-34, fig. 3A-E (description of females).

Types: CBEE; female holotype (XUX-2018-151) and 1 female paratype (XUX-2018-152); Myanmar, Kayah State, Loikaw District, Hpruso, Dokhule, 19.41°N, 97.10°E, 1157 m; 17.VII.2018; D. Li, F.X. Liu, X. Xu & L. Yu. Types not examined; no new material available.

Taxonomic remarks: Judging from illustrations in the original description, this species appears to be closely related to L. birmanicus and L. pinlaung from which it can be distinguished by a distinctly longer and narrower posterior stalk of the vulval plate (Aung et al., 2019: fig. 3B-E cf. Figs 14, 16). The body colouration of the female holotype (Aung et al., 2019: fig. 3A; however, carapace colouration given as “light brown” and leg colouration as “brown”, see p. 33 in same paper) is similar to that of young (not fully grown) females of L. birmanicus (Fig. 3G). In addition to close geographical proximity, this indicates a very close phylogenetic relationship between L. hpruso and L. birmanicus . We thus assume that the not yet known male of L. hpruso also possesses a distad-directed proventral contrategular process.

Distribution: This species is only known from its type locality (Fig. 1), about 30 km to the east of the known localities of L. birmanicus and roughly at the same altitude.
