Distribution. Eremaeus translamellatus Hammer, 1952 has a Holarctic distribution ( Subías, 2004, updated 2020). This is the first record from Turkey.

Remarks. Eremaeus translamellatus Hammer, 1952 can be distinguished from congeners by the presence of translamella; the shape of costulae; 11 pairs of notogastral setae and 5 pairs of anal setae. The body length for the species is recorded as 518-745 µm ( Walter et al., 2013). In this regard, the dimensions of the Turkish specimens (630- 660 µm) are in the range of the dimensions of the reported specimens.
