Paranemastoma umbo - Snegovaya, 2013: 185 (mention)

Type locality.

Georgia, Abkhazia region, Sokhumi Municipality, village Lata.

Occurrence data in Georgia.

Abkhazia • Lata near Tkvarcheli, Gulripshi Municipality; leg. V. Kalischevsky, September 1905 (Roewer 1951).

Global distribution.

Allegedly restricted to Georgia, but due to incorrect labeling, probably not occurring in the Caucasian ecoregion (Martens 2006; Schönhofer 2013, Snegovaya, 2013).

Remarks.

Martens (2006) explained that P. umbo displays a number of characters that are unusual in all Caucasian Paranemastoma species and he concluded that the relevant series in the Roewer collection in Senckenberg Museum/Frankfurt am Main, Germany, must have been labeled with the wrong location and, for the time being, should be removed from both the Georgian and the Caucasian lists.
