( Figs. 30–37 )

Diagnosis. The male of this species can be recognized by the following combination of characters: T2 with long basal petiole, clypeus bulging in the middle, mid femur weakly bulging below, and third segment of mid tarsus with definite angle near base of anterior margin. The female can be recognized by having: T2 with long basal petiole, clypeus regularly rounded, sides of mesosoma not red and S5–S6 not spotted with yellow, mesoscutum with three yellow spots, basal band on T4 incised or briefly interrupted medially, pronotal collar with small yellow spots.

Description. Female. Body length 9.3–10.7 mm (holotype 9.9 mm); fore wing length 6.9–7.8 mm (holotype 7.5 mm).

Head as wide as long in frontal view ( Fig. 32 ). Clypeus 1.1× as long as wide, strongly pointed apically, in lateral view regularly convex with a shallow depression in apical third, free apical margins crenate, basally separated from frons only by shallow depression. Distance between posterior ocelli larger than ocellar diameter. Mandibles tridentate, inner tooth short, median tooth almond shaped with convex margins, apical tooth long with straight inner margin. Antenna clavated, expanding apically, antennal scape 2.4× as long as its apical width, F1 2.4× as long as its apical width, F2–F4 slightly longer than wide, F5 about as long as wide, F6–F9 wider than long, F10 bullet shaped, 1.3× as long as its basal width. Temples very short in dorsal view. Vertex distinctly depressed behind posterior ocelli with median furrow.

Mesoscutum as long as width between tegulae, strongly convex in lateral view, notaulices present as indistinct furrows. Scutellum weakly convex, nearly flattened on disc. Metanotum weakly convex, nearly vertical. Propodeum weakly convex dorsally in lateral view, longitudinal median furrow shallow for entire length ( Fig. 33 ). Lateral faces of mesosoma nearly flat.

T1 6.9× as long as its maximum width, in lateral view almost linear from base to apex except weakly convex apical margin, in dorsal view distinctly expanded apically. T2 with long petiole at base, petiole 1.7× as long as wide.

Clypeus, except apical margin, with coarse small punctures and some sparser larger ones. Frons up to posterior ocelli punctured like clypeus, vertex with sparse fine punctures and interspaces microreticulate. Pronotum dull coriaceous, with some transverse striae on ventral corner and on posteroventral margin. Mesoscutum densely reticulate, dull. Scutellum densely punctured, interspaces as long as punctures diameter anteriorly, reduced to reticulation on posterior third. Metanotum smooth, with sparse moderately deep punctures. Posterior face of propodeum obliquely striate, striae becoming sparser apically; lateral faces with dense flat-bottomed punctures dorsally, weakly striate ventrally. Mesepisternum irregularly reticulate, coarser on dorsal part. Metaepisternum nearly smooth, with some sparse shallow punctures. T1 entirely smooth, T2–T6 microreticulate and shiny. Face up to anterior ocellus with dense golden pubescence. Dorsal face of mesosoma with short brownish setae, some longer ones on scutellum, metanotum and lateral margins of propodeum; lateral faces of mesosoma with short dense silvery pubescence. T1 with short whitish setae on lateral margins of basal half, T1–T6 with dense brownish pubescence, apical margin of S2–S4 and whole S5–S6 with long erect brownish whitish.

Color. Black; following parts yellow: central spot on clypeus, basal half of mandibles, inferior face of scape, dorsal face of pronotum, triangular spots between notauli and rectangular spot on posterior margin of mesoscutum, large anterolateral spots on scutellum separated by less than their diameter, anterior two thirds of metanotum, ventral half of posterior face of propodeum, large triangular spot below wings on mesepisternum, transverse spot below transverse furrow, posterior margin of dorsal plate of metaepisternum, thin lateral lines on anterior half of apical expansion of T1, elongate triangular lateral spots on petiole of T2, triangular anterolateral spots on T3, medially interrupted basal band on T4, small lateral spots on T5, anterolateral rounded spots on S3–S4, apical half of fore femur, apical spot on mid and hind femora, outer face of fore and mid tibiae, basal spot on hind tibia, basal spot on fore and mid basitarsus; underside of flagellum reddish-orange, darker basally; apex of clypeus, mandibles and indistinct markings on mesosoma and fore legs dark reddish.

Male. Body length 9.3–9.6 mm; fore wing length 6.8–7.4 mm.

Like female, except: head 1.2× as wide as long in frontal view ( Fig. 35 ); clypeus about as long as wide, weakly pointed apically and bulging in the middle; antenna weakly clavate, antennal scape 2.2× as long as wide apically, F1 2.2× as long as wide, F2 slightly longer than wide, F3–F6 about as long as wide, F7–F10 wider than long, F11 bullet shaped and 1.4× as long as wide basally; lateral faces of propodeum weakly depressed anteriorly; T1 7.9× as long as its maximum width and weakly convex basally; petiole of T2 shorter, 1.6× as long as wide; mid femur bulging below at base ( Fig. 37 ); mid tarsus modified, anterior lobe of segment 2 expanded and pointed apically, anterior margin of segment 3 with a distinct angle near base ( Fig. 36 ); apical depressed part of clypeus nearly impunctate; lateral depressions of propodeum densely covered by brownish setae; long setae on T1 less abundant; apex of T5–T7 with long setae; S7 concave with a median furrow.

Color. Like female, except: clypeus without central spot, mandibles entirely yellow, small apical spot on scape, posterior face of propodeum entirely yellow except basal rectangular spots and base of lateral margins, markings on metaepisternum larger, lines on T1 shorter, lateral spots on T3 smaller, large basal band on T4–T6, large basolateral spots on T7, spots on tarsi absent on mid legs and reduced on fore legs.

Distribution. Philippine Islands: Mindanao, Mindoro.

Etymology. I am pleased to name this species in honor of Dr. James M. Carpenter (AMNH), as a sign of esteem and gratitude for the help provided in the past years.
