Material: 1♂, 1♀, Turkey, İzmir Province, Selçuk, Barutçu Cave (38°00’20”N 27°20’44”E), entrance zone, elev. 140 m, 17.VI.2021, M. Elverici leg.
Diagnosis. Zodarion samos Bosmans, 2009 belongs to the Eastern Mediterranean lutipes group (sensu Bosmans, 2009) recognized by the morphology of the male palp with a very long embolus originating at the baso-lateral side of the tegulum and of the epigyne with an anteromedian hood and with spermathecae provided with several coiled ducts. This species can be separated from all other species of the lutipes group by the gradual narrowing of the robust, thorn-shaped tibial apophysis of the male (vs. as long or mostly longer than wide) (Figs. 9–11); the female can be separated from other congroupes by the spermathecae with two large globular chambers adjacent to anteromedian hood and connected laterally to three adjoining coils arranged loosely (Figs 12–16).
