Ponera szentivanyi

Only known from two type specimens.

Identification
Taylor (1967) - The 4-segmented club and lack of an incised mesometanotal suture allow placement to the tenuis group.

Differs from Ponera petila by its larger size, narrower head (CI 75 versus 78), and other dimensional differences. Sculpturation of the head and mesosoma of szentivanyi is about intermediate between that described for petila and szaboi.

Differs from Ponera szaboi by its smaller size (HW 0.30-0.31 mm, PW 0.23 mm, DPW 0.15 mm; opposed to 0.34 mm, 0.28 mm and 0.21-0.24 mm respectively in szentivanyi), relatively short scapes (SI 79-83, against 94 in szentivanyi) and a less intense sculpturation of the mesosoma.

Distribution
