= Rophites (Trilia) deserticolus ssp. tadshicus Warncke, 1979 : 118 (unjustified replacing name for T. montana Popov, 1957, preoccupied in the genus
Rophites).

Distribution. Tajikistan (known only from holotype).

Remark: there are three names in these two genera that create an awkward homonymy problem: Halictoides montanus Morawitz 1889 (now in Dufourea, as a synonym of clavicrus), Trilia montana Popov 1957 (originally in Dufourea since Vachal's Trilia was a subgenus, moved out presumably by Popov since he seems to have used Trilia as a genus, but later placed back there again by Michener), and Rophites algirus montanus Ebmer 1978. While it seems possible that Ebmer'sname *may* never have been placed in the same genus as Morawitz', and Popov's *may* never have been in the same genus as Ebmer's (these possibilities might need to bechecked and ruled out), Popov's name is clearly a homonym that MUST be given a replacement, since there are authors who do not treat Trilia as a separate genus (see Art. 59 - but note that 59.2 does not apply). For authors who insist thatTrilia is a genus, they are allowed to use Popov'sname (under 59.4), but it cannot be used in Dufourea, as it is a homonym there of Morawitz' name.
