SUBFAMILY PONERINAE - Genus Streblognathus
|Contents - Ponerinae - PONERINAE Introduction|
Diagnostic Features - Sides of petiole converging dorsally into a sharp, longitudinal crest, which runs the length of the segment. Posterolateral margins of petiole also sharply angulate in the dorsal half, these sharp angles meeting the dorsal crest at its posterior end. Anterior clypeal margin broadly concave, the concavity terminating at each side in a prominent angle or tooth-like projection. See Arnold (1915: 41) (below).
Mayr's (1862) genus description is at . Robertson (2002) made a fresh study and described peetersi, his paper is at - .
