Diagnosis (reproduced from Bayer 2012): Males with embolus arising medially at distal half of tegulum ( Bayer 2012, figs. 31b, 37b, 48b). In males, either coxae of legs I ( Bayer 2012, figs 82l,r) or the most proximal part of palpal femur ( Bayer 2012, fig. 35d) ventrally with field of distinct macrosetae.

Females are distinguished from those of all other species groups except the ancoralis -group by the following combination of characters: Epigyne without tegimentum ( Bayer 2012, figs 69a, 89m) and strongly sclerotised epigynal field ( Bayer 2012, figs 87c–d), with small, slit-like copulatory openings ( Bayer 2012, fig. 37d) and mostly converging anterior sections of epigynal slits ( Bayer 2012, figs 27e, 36a) and median septum mostly broader than long ( Bayer 2012, figs 32a, 36a, 41e); receptacula not distinctly round, copulatory ducts without distinctly rough surface ( Bayer 2012, fig. 80b) and bulbous ( Bayer 2012, fig. 63b) or twisted ( Bayer 2012, fig. 59b) sections and at most 1.5 times broader than diameter of one receptaculum. Females are distinguished from those of the ancoralis - group by the spermathecal heads located on the receptacula (spermathecae) and by the copulatory ducts mostly narrow and shorter than the diameter of one receptaculum ( Bayer 2012, figs 37e, 41f, 47b, 49b).

The close relationship to the ancoralis -group and a possible paraphyly is discussed in the paragraph below the heading of the ancoralis -group above. The himalayanus -group includes 11 species ( Psechrus himalayanus Simon, 1906 , P. marsyandi Levi, 1982 , P. inflatus Bayer, 2012 , P. ghecuanus Thorell, 1897 , P. pakawini Bayer, 2012 , P. luangprabang Jäger, 2007 , P. demiror Bayer, 2012 , P. j a eg e r i Bayer, 2012, P. vivax Bayer, 2012 , P. arietinus sp. nov., P. insulanus sp. nov.) and is distributed in Northern India, Nepal, Bhutan, China, Myanmar, Thailand, Laos, Cambodia and Vietnam.
