Drabovia sp.

Fig. 11G .

Material.— Two specimens from the Porkuni Regional Stage , Kuldiga Formation , Hirnantian (Upper Ordovician); western Latvia, Vilcini-19 core (on depths 901.1 m and 901.2 m; collection GIT 542 )

Remarks.—Two small, dorsal valves with a suboval outline, a nodule-like myophore and short anteriorly-narrowing cardinal process shaft and erect subparallel brachiophore plates are similar to those of Drabovia westrogothica Bergström from Västergötland, Sweden ( Bergström 1968) and Drabovia? minuta Hints, 2012 ). However, the Latvian specimens are insufficient for detailed comparison with the other species of Drabovia .
