Ratcheuma excorne Golovatch, 1985

Fig. 160

Type locality. GEORGIA: Racha Mt. Ridge, Ambrolauri District, Cave Nikortsminda, near village Nikortsminda.

Material studied (total: 1 male). Topotype (total: 1 male). GEORGIA: 1 male, Racha Mt. Ridge, Ambrolauri District , Cave Nikortsminda, near village Nikortsminda, 40–50 m deep, 22 Oct. 1981, S. Golovatch leg. ( ZMUM ρ3231).

Distribution. Georgia (known only from Cave Nikortsminda (= Meliis)) ( Fig. 170 , violet diamond).

Notes. Golovatch (1985: 42) stated the presence of “…a hinder pair of parabasal long and wide flagelloid projections…” on the anterior gonopods, but actually this was a pair of lamellae. Male leg-pair 7 with a wide, posterior, coxal lamella with setae, Golovatch (1985: 45, fig 2, 2) illustrated, but failed to describe this in the text. Golovatch also erred in allotting 30, not 31, body segments to this genus and species.
