Arpactophilus orowe View in CoL sp. nov.
( Figs. 8–9 View FIGURES 5 – 9 , 83–84 View FIGURES 83 – 88 )
Diagnosis. Arpactophilus orowe is the only New Caledonian species in the genus with the combination of a sternum II with a bulge ( Fig. 84 View FIGURES 83 – 88 , and as is Fig. 2 View FIGURES 1 – 4 ), a dark reddish-brown mandible with some yellow anteriorly, mostly black femora, a flat midventral line without an elevated ridge, a gena with dense punctation and associated setae, a black pronotal lobe, a metatibia with a well-delimited dark brown area ( Figs. 8–9 View FIGURES 5 – 9 ), and a roughly punctured frons without a distinct carina parallel to the inner compound eye margin ( Fig. 83 View FIGURES 83 – 88 ).
Description. FEMALE: Total length 5.9–6.3 mm, mean = 6.0 mm; forewing length 3.6–3.8 mm, mean = 3.7 mm.
Body black, with areas of yellow and brown. Yellow: mandible laterally at base; trochanters; femora apically; tibiae, except apical area of metatibia; tarsi. Brown: palpi; antenna; coxae; most of femora; apical area of metatibia. Most of mandible dark reddish-brown. Wings hyaline; pterostigma dark brown.
Head about 1.1 × as long as wide in frontal view. Apical margin of clypeus strongly projecting medially with slight shallow concave incision ( Fig. 83 View FIGURES 83 – 88 ). Apical margin of labrum slightly bilobed. Ventral mandibular tooth about ¼–1/5 of total mandibular length, not reaching opposite mandibular base. Palpal formula 5:4. Frons colliculate with dense short setae. Frontal carina present from median ocellus to apical margin of clypeus, elevated to a small point at basal clypeal margin. Scape 3.5 × 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 dense punctation and dense, short setae, without tubercles, spines, or dorsoventral carina. Hypostomal midventral line faint anteriorly, carinate posteriorly with bordering short transverse carinulae on hypostomal integument.
Mesosoma about 1.8 × as long as wide in dorsal view. Propodeum about 0.9 × as long as wide in dorsal view. Mesosoma colliculate or imbricate and densely punctured ( Fig. 84 View FIGURES 83 – 88 ), 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 ). Pitted sulcus present posterior to mesoscuto-mesoscutellar sulcus. Hypersternal sulcus barely visible, present as small impression close to omaulus. Metafemur 2.9 × as long as wide. Metatibia with a well-delimited dark brown, flattened area apically ( Figs. 8–9 View FIGURES 5 – 9 ). Pretarsal claws without teeth. 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. 84 View FIGURES 83 – 88 ). Metasomal sternum II swollen medially, forming bulge (as in Fig. 2 View FIGURES 1 – 4 ). Pygidium with broad row of silk setae.
MALE: Unknown.
Remarks. Arpactophilus orowe is similar to A. kumak , A. vamale , A. numee , A. xaragure , A. nyelayu , A. pwapwa , 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 .
