Oxyopomyrmex pygmalioni sp. nov.

( Figs. 61, 62, 63, 84)

Etymology. Named after the Cypriot king Pygmalion. According to Ovid’s narrative, Pygmalion was a sculptor who fell in love with an ivory statue which he had carved. Through Aphrodite’s blessing the sculpture changed to a woman and the king could fortunately married her. Oxyopomyrmex pygmalioni is the most densely and distinctly sculptured species, reminiscent of a raw sculpture.

Biology. Borowiec collected specimens on grassy coastal terraces of cliffs. Despite low temperatures (16 ° C) and windy weather, the workers were active and were hand collected between clumps of grass. The following ant species were collected in the area: Messor sp. (hellenius complex), Plagiolepis pallescens sensu Radchenko , and Tapinoma simrothi Krausse.

Differential diagnosis. Worker. Oxyopomyrmex pygmalioni belongs to the group of species characterized by a distinctly punctate propodeum. It is distinguished from O. emeryi and O. oculatus by the longitudinal striae covering whole frontal surface of the head and the presence of rugosity on dorsal surface of the pronotum. From O. negevensis it differs by the lack of the transverse striation on dorsal surface of the pronotum, the shiny abdomen and by more dense and thicker hairiness at the scape and legs.
