Arpactophilus vamale View in CoL sp. nov.
( Figs. 103–104 View FIGURES 101 – 106 )
Diagnosis. Arpactophilus vamale is the only New Caledonian species in the genus with the combination of a sternum II with a bulge ( Fig. 104 View FIGURES 101 – 106 , and as in Fig. 2 View FIGURES 1 – 4 ), a dorsally-interrupted occipital carina ( Fig. 6 View FIGURES 5 – 9 ), dark brown femora, a mostly flat hypostomal midventral line that is slightly angulate medially, a light brown metatibia without a prominent darker colored area, and a roughly punctured frons without a distinct carina parallel to the inner compound eye margin ( Fig. 103 View FIGURES 101 – 106 ).
Description. FEMALE: Total length 5.0 mm; forewing length 3.3 mm.
Body black, with brown and dark yellow. Dark yellow: trochanters; femora apically and basally; tibiae; tarsi. Brown: antenna; anterior pronotal margin; tegula; coxae; most of femora. Mandible reddish-black. Wings slightly infumate; pterostigma dark brown.
Head about 1.1 × as long as wide in frontal view. Apical margin of clypeus strongly projecting medially, medioapical margin nearly straight ( Fig. 103 View FIGURES 101 – 106 ). Apical margin of labrum projecting medially, with a shallow Vshaped incision medially and laterally, forming four small lobes. Ventral mandibular tooth about ¼–1/5 of total mandibular length, not reaching opposite mandibular base. Palpal formula 5:4. Frons finely carinate-reticulate with dense short setae. Frontal carina present from median ocellus to midlength of clypeus, forming a flat point at basal clypeal margin. Scape 3.3 × as long as wide. Ocellar triangle anterior of tangent between upper posterior orbits of compound eyes, lateral ocelli anterior of tangent by more than their diameter. Occipital carina interrupted dorsally ( Fig. 6 View FIGURES 5 – 9 ). Gena imbricate, with sparse punctation and associated setae, without tubercles, spines, or dorsoventral carina. Hypostomal midventral line faint anteriorly, carinate posteriorly, slightly angulate medially.
Mesosoma about 1.8 × as long as wide in dorsal view. Propodeum about 0.9 × as long as wide in dorsal view. Mesosoma colliculate, also finely carinulate laterally ( Fig. 104 View FIGURES 101 – 106 ) and densely punctured dorsally, except on propodeum; lateral surface of propodeum transversely carinulate; dorsal surface of propodeum coarsely reticulate (similar to pattern in Fig. 18 View FIGURES 16 – 22 ). Broadly pitted sulcus present posterior to fine mesoscuto-mesoscutellar sulcus. Hypersternal sulcus absent. Metafemur 2.7 × as long as wide. Metatibia without differently colored area apically. Pretarsal claws with a small tooth at base. Forewing with two submarginal cells; anterior border of submarginal cell II shorter than posterior border. Hind wing with five distal hamuli.
Metasoma polished, punctation sparse ( Fig. 104 View FIGURES 101 – 106 ). Metasomal sternum II swollen medially, forming bulge (as in Fig. 2 View FIGURES 1 – 4 ). Pygidium with broad row of silk setae apically.
MALE: Unknown
Remarks. Arpactophilus vamale is similar to A. kumak , A. pwapwa , A. numee , A. xaragure , A. nyelayu , A. orowe , and A. arboreus as all share the combination of a dark brown or black metasoma with a bulge on the metasomal sternum II and a dark brown or black clypeus with a medially strongly projecting apical margin that has no or only a small incision medially. See remarks-section of A. kumak .
