Poneracantha lanei (Kempf, 1960) Specimen Label

Its morphology puts it in the rastrata group of millipede hunters. (Lattke 1995)

Identification

A member of the rastrata complex (in the rastrata subgroup of the rastrata species group). Relatively small eyes; clypeal lamella medianly concave; Promesonotal suture vestigial and small denticles on the propodeum; node elongate, with transverse costulate. Kempf (1968:377) reports a series with transverse costulate on the anterior pronotal face, differing from the longitudinal sculpture of the type series. (Lattke 1995)
