and male is at . Santschi's (1937g)
description of apicalis is at .
Brown (1975: 47) described it as close to lamellosa
but differing in the alitrunk profile being continuous and with the
dorsal surface of the petiole node rising gradually to the posterior
border, then dropping suddenly in to the posterior face which it
overhangs; in lamellosa the convex dorsum of the petiole node
rounds into the posterior face. He noted the similarity in descriptions
of arnoldi and lamellosa apicalis, which he
synonymised, and that viehmeyer could be the same as arnoldi.
Brown (1975) describes it as ground-dwelling foraging on
the ground or on trees and shrubs; observed by Arnold (1915) in
Zimbabwe as feeding entirely on adult beetles, especially Tenebrionidae.
