75. Prosopistoma pennigerum (Müller, 1785)

= Prosopistoma foliaceum in Elanidze (1956), Sadovsky (1940a, 1946, 1948)

Distribution in Georgia: Kakheti ( Elanidze, 1956), Kvemo Kartli ( Sadovsky, 1940a, 1946, 1948), Samtskhe-Javakheti ( Sadovsky, 1940a).

Several publications reporting the occurrence of some (sub)genera without indication on species level are absent in the list above. These include the following:

1. Sadovsky (1946, 1948) indicated the existence of the genus Ametropus Albarda, 1978 (family Ametropodidae ) in the river Kura (near Tbilisi). However, there are neither vouchers available nor other sources corroborating the occurrence of any representatives of the family Ametropodidae in Georgia. Additional work is needed to confirm these findings. The same can be said about the representatives of the genus Brachycercus Curtis, 1834 , reported by Sadovsky (1948) in Kakheti (Alazani River) and Kvemo Kartli (Kura River).

2. Sadovsky (1948), Elanidze (1951), Palatov (2013), and Godunko et al. (2015) reported subgenus (of Baeti s) Acentrella Bengtsson, 1912 from Kakheti (Alazani), Kvemo Kartli (Kura), Imereti (Rioni and Tskaltsitela), Abkhazia, and Adjara. Further work is needed to determine the species identity of these specimens.

3. Schletterer and Kuzovlev (2007) reported the genus Prosopistoma Latreille, 1833 from Samtskhe- Javakehti (Lake Tabatskuri). It represents most probably Prosopistoma pennigerum (Müller, 1785) , since there is only one species of the genus Prosopistoma reported in Europe and the Caucasus at present ( Bauernfeind and Soldán, 2012).
