Arpactophilus xaragure View in CoL sp. nov.
( Figs. 7 View FIGURES 5 – 9 , 109–110 View FIGURES 107 – 112 )
Diagnosis. Arpactophilus xaragure is the only New Caledonian species in the genus with the combination of a sternum II with a bulge ( Fig. 110 View FIGURES 107 – 112 , and as in Fig. 2 View FIGURES 1 – 4 ), a dorsally-interrupted occipital carina ( Fig. 6 View FIGURES 5 – 9 ), a brown mandible with yellow in front, brown femora, a flat, non-angulate hypostomal midventral line, a gena with sparse punctation and associated setae, a brown pronotal lobe, a metatibia with a brown area on the metatibia ( Fig. 7 View FIGURES 5 – 9 ), and a roughly punctured frons without a distinct carina parallel to the inner compound eye margin ( Fig. 109 View FIGURES 107 – 112 ).
Description. FEMALE: Total length 5.1 mm; forewing length 3.7 mm.
Body black, with areas of yellow and brown. Yellow: mandible laterally at base; palpi; scape; anterior pronotal margin; trochanters; femora at joints; tibiae, except apical area on metatibia. Brown: most of mandible; pedicel; flagellum; pronotal lobe apically; tegula; most of femora; apical area on metatibia. Wings faintly infumate; pterostigma dark brown.
Head about 1.1 × as long as wide in frontal view. Apical margin of clypeus strongly projecting medially, with a shallow V-shaped incision medially ( Fig. 109 View FIGURES 107 – 112 ). Apical margin of labrum projecting medially with a slight shallow V-shaped incision medially. Ventral mandibular tooth about ¼–1/5 of total mandibular length, not reaching opposite mandibular base. Palpal formula 5:4. Frons finely reticulate with dense short setae. Frontal carina present from median ocellus almost to apical margin of clypeus, elevated to a small point at basal clypeal margin and to ridge on apical half of clypeus. 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 carinate with bordering sparse and short transverse carinulae on hypostomal integument, not angulate.
Mesosoma about 1.7 × as long as wide in dorsal view. Propodeum about 1.3 × as long as wide in dorsal view. Mesosoma imbricate with dense punctation ( Fig. 110 View FIGURES 107 – 112 ), except of propodeum; mesopleuron also transversely carinulate; lateral surface of propodeum transversely carinate; dorsal surface of propodeum coarsely reticulate (similar to pattern in Fig. 18 View FIGURES 16 – 22 ), apically transversely carinate. Pitted sulcus present posterior to mesoscutomesoscutellar sulcus. Hypersternal sulcus present as small impression close to omaulus. Metafemur 2.6 × as long as wide. Metatibia with brown area apically, area slightly swollen but without flattened area delimited by ridges or carinae ( Fig. 7 View FIGURES 5 – 9 ). Pretarsal claws without teeth. Forewing with two submarginal cells; anterior border of submarginal cell II slightly shorter than posterior border. Hind wing with five distal hamuli.
Metasoma polished, punctation sparse ( Fig. 110 View FIGURES 107 – 112 ). 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 xaragure is similar to A. kumak , A. vamale , A. numee , A. orowe , 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 .

Etymology. The specific epithet is taken from the name Xârâgurè , one of the New Caledonian native languages. It is treated as a noun in apposition.
