All Caucasian species of the subgenus Tetramelus are very similar in general apperance. They are small or middle-sized, light yellowish-brown, microphthalmous, with slender antennae and legs. The body length of Euconnus ( Tetramelus) kraussi is 1.40–1.60 mm. In the original description the body length of Euconnus ( Tetramelus) marinae is stated to be 1.55–1.75 mm ( Franz 1979). The length of this wide range was already put in doubt ( Vít & Hlaváč 1998: 146). All three syntypes in NMW were measured and they have the following lengths: 1.57; 1.43; 1.43 mm. Consequently, the Franz’s measurements were not correct.

During the present study, the following material was studied:

Tetramelus nachuzrischwilii Franz : HOLOTYPE, ♂: five labels, “Zentralkaukassus / lg. H. Franz, 1.-8.6.77 [date crossed out]“ [printed, white], “Umg. Ananuri / b. Tbilisi “ [white, printed], “ E. ( Tetramelus ) / nachuzraschwili m. / det. H. Franz “ [white, handwriten and printed], „ HOLOTYPE “ [red, handwriten], “ HOLOTYPE / Euconnus ( Tetramelus) / nachuzrischwili Franz / = E. T. kraussi Reitter / P. Hlaváč det., 2020“ [red, printed] ( NMW).

PARATYPES, 9 sps: four labels, “Zentralkaukassus / lg. H. Franz, 1.-8.6.77 [this dates are striked down]“ [printed, white], “Umg. Ananuri / b. Tbilisi “ [white, printed], “ E.

Hlaváč det., 2020“ [red, printed] ( NMW) .

Remarks. All ten specimens of the type series have the same collecting date, 1- 8.6.1977, there are no specimens with the date 12.7.1985, indicated in the original description ( Franz 1986: 42).

Tetramelus marinae Franz : LECTOTYPE, ♂, here designated: four labels, “ Kachetien / Umg. Shuante, 800 m “ [white, printed], “ Zentralkaukassus / lg. H.
