Worker description

Major. — Head bearing very short appressed background hairs over entire surface and a few thick standing hairs dorsally; head in lateral view highly raised at the border of frons and vertex, not or hardly impressed on vertex; frons flat or very weakly impressed medially; frons and anterior part of vertex punctured, overlain by longitudinal rugulae; posterior part of vertex and dorsal and lateral faces of vertexal lobe largely rugosopunctate, shagreened or almost smooth; frontal carina well developed horizontally, partly overhanging antennal scrobe; median part of clypeus punctured, with a relatively weak median longitudinal carina; median and submedian processes of hypostoma inconspicuous or poorly developed; lateral processes conspicuous; outer surface of mandible (excluding area around the base) smooth or shagreened, bearing short appressed hairs; antenna with a 3-segmented club; maximal diameter of eye much longer than antennal segment X. Promesonotal dome at most with a few standing hairs, in lateral view with a conspicuous prominence on its posterior slope; humerus weakly produced laterad; the dome at the humeri usually narrower than at the bottom, but sometimes a little broader than at the bottom; propodeum without standing hairs. Petiole much longer than postpetiole (excluding helcium); postpetiole not massive. First gastral tergite weakly punctured anteriorly and shagreened to smooth posteriorly.

Minor. — Dorsum of head punctured, bearing sparse, very short appressed background hairs, and having only a few standing hairs; preoccipital carina conspicuous dorsally and laterally; median part of clypeus weakly punctured; median longitudinal carina of clypeus conspicuous to weak, or absent; antenna with a 3- segmented club; scape exceeding posterior margin of head by 1.5× length of antennal segment II or more; maximal diameter of eye almost as long as or a little shorter than antennal segment X. Dorsal and lateral faces of mesosoma punctured (punctuation weaker in posterolateral part of promesonotal dome); promesonotal dome bearing a few short and thick standing hairs dorsally, in lateral view with a conspicuous prominence or mound on its posterior slope; humerus of the dome in dorso-oblique view not or very weakly produced laterad; propodeum without standing hairs. Petiole much longer than postpetiole (excluding helcium); postpetiole not massive.

Recognition: This species is well characterized among Indo-Chinese species by the combination of the following characteristics: in the major and minor dorsum of head with a few thick standing hairs among very short appressed background hairs; in the major head in lateral view strongly raised at the border of frons and vertex; in the major frontal carina well developed horizontally, partly overhanging antennal scrobe; in the minor dorsum of head and dorsal and lateral faces of mesosoma punctured; in the major and minor promesonotal dome in lateral view with a conspicuous prominence or mound on its posterior slope.

The major of P. capellinii is similar to that of P. planifrons , but is easily separated from the latter by the following characteristics of the latter: head in lateral view poorly raised at the border between frons and vertex; vertex and lateral faces of vertexal lobe reticulate; first gastral tergite longitudinally rugoso-punctate entirely or excluding somewhat polished posteromedian part.

Distribution & bionomics: Known from N. Vietnam, China ( Wheeler 1927b), Thailand, Sumatra and Java. This species occurs in open habitats, such as annual cropping fields, and nests in the soil.
