Arpactophilus nemi View in CoL sp. nov.
( Figs. 73–74 View FIGURES 71 – 76 )
Diagnosis. Arpactophilus nemi is the only New Caledonian species in the genus with the combination of two submarginal cells in the forewing, a black clypeus and reddish-black mandible ( Fig. 73 View FIGURES 71 – 76 ), a dorsally-interrupted occipital carina ( Fig. 6 View FIGURES 5 – 9 ) and a black metasoma ( Fig. 74 View FIGURES 71 – 76 ) without a bulge on sternum II (as in Fig. 1 View FIGURES 1 – 4 ).
Description. FEMALE: Total length 4.9 mm; forewing length 3.0 mm.
Body black, with areas of yellow and brown. Yellow: palpi; scape; pedicel; anterior pronotal margin; tegula; coxae apically; trochanters; femora basally and apically; tibiae; tarsi. Brown: flagellum; pronotal lobe; most of coxae; most of femora. Mandible reddish-black. Wings hyaline; pterostigma dark brown. Labrum not visible.
Head about 1.2 × as long as wide in frontal view. Apical margin of clypeus strongly projecting medially, with medioapical margin nearly straight ( Fig. 73 View FIGURES 71 – 76 ). Labrum not visible. Ventral mandibular tooth about ¼–1/5 of total mandibular length, not reaching opposite mandibular base. Palpal formula probably 4:3 (not completely visible). Frons finely reticulate with short dense setae. Frontal carina present from median ocellus to midlength of clypeus, elevated to small point at basal clypeal margin. Scape 3.6 × 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, slightly angulate at oral fossa.
Mesosoma about 1.8 × as long as wide in dorsal view. Propodeum about 0.9 × as long as wide in dorsal view. Mesosoma imbricate to colliculate ( Fig. 74 View FIGURES 71 – 76 ), except dorsal surface of propodeum; lateral surface of propodeum also transversely carinulate; dorsal surface of propodeum transversely carinulate and basally reticulate (similar to pattern in Fig. 19 View FIGURES 16 – 22 ). Pitted sulcus present posterior to mesoscuto-mesoscutellar sulcus. Hypersternal sulcus absent. Metafemur 2.6 × as long as wide. Metatibia without differently colored area apically. 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, with sparse punctation ( Fig. 74 View FIGURES 71 – 76 ). Metasomal sternum II without bulge (as in Fig. 1 View FIGURES 1 – 4 ). Pygidium with broad row of silk setae.
MALE: Unknown.
Remarks. Arpactophilus nemi is similar most to the group of A. kumak , A. vamale , A. nyelayu , A. numee , A. xaragure , A. orowe , A. pwapwa , and A. arboreus in that all these species share a similar body size, coloration and a black clypeus with a medially strongly projecting apical margin that has no or only a small incision medially. In comparison to these species A. nemi has a flat metasomal sternum II that does not form a bulge. It is the only species with the combination of this clypeus form and color, a black metasoma and the absence of the bulge on the metasomal sternum II.
Material examined. HOLOTYPE ♀: “ NEW CALEDONIA 8926: 21°11’S x 165°18’E, 850m, Aoupinie top camp. 23 Nov 2001 – 1 Feb 2002. Burwell, Monteith. Malaise” [QM].
Etymology. The specific epithet is taken from the name Nemi , one of the New Caledonian native languages. It is treated as a noun in apposition.
