Comment. Plinthisus minutissimus is a very small species which was observed to live inside nests of Formica rufa Linnaeus, 1758 and F. lugubris Zetterstedt, 1838 (= F. congerens Nylander, 1846) (PUTON 1878). However, PÉRICART (1998) mentions that he always collected this species from mosses. The examined specimen belongs to the rare macropterous form. This species has a wide distribution range in southern Europe (Austria, Bosnia and Herzegovina, Croatia, France, Germany, Greece (Corfu and Crete as well), Italy, Macedonia, Portugal, Romania, Spain, and Switzerland) and North Africa (Algeria, Morocco, and Tunisia) (PÉRICART1998). It is distinguished from other species of its subgenus by its relatively small size, shiny dorsum and castaneous coloration (Fig. 5H) (PÉRICART 1998).

Distribution in Turkey. İzmir (this work).
