PLEBEIA (PLEBEIA) SCHROTTKYI (FRIESE)

Figures 15, 37

DESCRIPTION: Head: Size small relative to body size (fig. 15). Antennal papilla tuberculate, moderate in size, bearing 4–5 sensilla. Labrum moderate in size but clearly narrower than distance between antennal papillae; presumably because of poor condition of specimen, multipronged spicules appearing more obscure than in other species relative to somewhat pigmented hemispherical sensilla.

Mandible (fig. 37) tapering from moderately robust base to narrow, pigmented apex that is parallel sided; mandible bearing sharp spines along dorsal apical surface that extend around blunt apical concavity.

Body: As described for Plebeia (Scaura) latitarsis (fig. 16).
