Diagnosis.

MALE: Head in frontal view about as wide as high; clypeus as wide as high ( Figs 1 , 3 ), in lateral view with anterior margin slightly convex dorsally and nearly straight ventrally ( Fig. 10 ); labrum broadly rounded apically; apicalmost tooth of mandible long and sharp; gena narrow ( Fig. 10 ); antennal flagellomeres IX and X flattened ventrally, flagellomere X smaller than preceding flagellomeres; mesosoma slender, 1.4 × as long as high and 1.3 × as long as wide; pronotum with distinct and well-developed striae on vertical anterior face; propodeum with shallow and narrow (less than half as wide as width of propodeum) concavity on posterior face; propodeal valvula subrectangular, not fused to submarginal carina; propodeal orifice oval; second submarginal cell of fore wing petiolate basally; metasomal segment I proportionally longer than that of any other species, 0.6 × as long as mesosoma; sternum VII with longitudinal carina at least in anterior half, latero-basally with brush-like setae. FEMALE: Head in frontal view about as wide as high; clypeus proportionally wider than that of male, 1.2 × as wide as high ( Fig. 2 ); mesosoma 1.5 × as long as wide.

Material examined.

PHILIPPINES: LEYTE I.: 1 ♂ (IUNH; holotype of Pachymenes gregarioides ), labeled "Palo, Leyte, Philippines, 1978.3.20, J. Kojima" and "Holotypus Apodynerus gregarioides Giordani Soika"; 1 ♂ (SEIHU; holotype of Philippodynerus omicroniformis ), labeled "Naga-Naga, Palo, Leyte, Philippines, 1978.3.25, J. Kojima" and " Philippodynerus omicroniformis nov. Spec. ♂, J. Gusenleitner, det. 1996, Holotypus"; LUZON I.: 1 ♀, C.L.S.U. [Central Luzon State University], Munoz, Nueva Ecija, 18 Apr.1980, J. Kojima (IUNH; paratype of Pachymenes gregarioides ).

Remarks.

This species is only known from the areas given in the original description (Luzon and Leyte, the Philippines). Giordani Soika (1994) recorded this species from Lokojengo on Sumba Island, Lesser Sunda Islands. The occurrence of this species on Sumba, however, needs confirmation, considering the unusual disjunct distribution and possibility of misidentification with the other species known from the Lesser Sunda Islands, such as Apodynerus rufipes Giordani Soika and Apodynerus quadricolor Giordani Soika.
