Arpactophilus nere View in CoL sp. nov.
( Figs. 77–78 View FIGURES 77 – 82 )
Diagnosis. Arpactophilus nere is the only New Caledonian species in the genus in which the clypeus and labrum have two, prominent, pointed long teeth ( Fig. 77 View FIGURES 77 – 82 ). Other distinctive features are the yellow markings on clypeus and frons ( Fig. 77 View FIGURES 77 – 82 ) as well as the yellow mesoscutellum.
Description. FEMALE: Total length 5.4 mm; forewing length 3.6 mm.
Body black, with areas of yellow. Yellow: lateral clypeus; labrum (slightly darker); mandible; palpi; scape; pedicel; area on frons close to inner compound eye margin, broad on level of scape, narrow towards vertex ( Fig. View FIGURES 77 – 82
77); area around mandibular base; anterior pronotal margin; dorsal transversal band on pronotum; band on pronotum parallel to ventral pronotal margin; pronotal lobe; area on mesopleuron below pronotal lobe; area on mesopleuron next to lower 2/3 of mesopleural fissure; tegula; anterior part of mesoscutellum (similar to coloration in Fig. 19 View FIGURES 16 – 22 ); legs. Flagellum brown. Wings hyaline; pterostigma dark brown.
Head about 0.9 × as long as wide in frontal view. Apical margin of clypeus projecting medially with steep Vshaped incision, apicolateral angles of incision forming two long, pointed teeth ( Fig. 77 View FIGURES 77 – 82 ). Apical margin of labrum projecting medially and with deep V-shaped incision, apicolateral angles of incision forming two long, pointed teeth that project beyond apex of clypeal margin ( Fig. 77 View FIGURES 77 – 82 ). Ventral mandibular tooth nearly 1/3 of total mandibular length, almost reaching opposite mandibular base. Palpal formula 4:3. Frons imbricate with sparse setae. Frontal carina present from median ocellus to upper half of clypeus, there slightly elevated. Scape 7.2 × 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 setae, without tubercles, spines, or dorsoventral carina. Hypostomal midventral line faintly carinate, posteriorly with bordering short transverse carinulae on hypostomal integument, not angulate.
Mesosoma about 1.8 × as long as wide in dorsal view. Propodeum about 1.0 × as long as wide in dorsal view. Mesosoma imbricate ( Fig. 78 View FIGURES 77 – 82 ), except dorsal surface of propodeum; lateral surface of propodeum also transversely carinulate; dorsal surface of propodeum coarsely reticulate (similar to pattern in Fig. 18 View FIGURES 16 – 22 ). Impressed, but not pitted sulcus present posterior to mesoscuto-mesoscutellar sulcus. Hypersternal sulcus present as concave elongate area close to omaulus. Metafemur 3.5 × as long as wide. Metatibia without differently colored area apically. Pretarsal claws with teeth. Forewing with two submarginal cells; anterior border of submarginal cell II shorter than posterior border. Hind wing with five distal hamuli.
Metasoma matt, punctation sparse. Metasomal sternum II without bulge (as in Fig. 1 View FIGURES 1 – 4 ). Pygidium with broad row of silk setae apically.
MALE: Difference from female aside from genitalic structures: generally lighter brown; teeth on apical margin of clypeus much smaller and not pointed; mandible tooth shorter. Metasomal sternum VIII slightly narrow.
Remarks. Arpactophilus nere is easily identifiable by its prominent pointed teeth of the apical margin of clypeus and labrum ( Fig. 77 View FIGURES 77 – 82 ). The most similar species is A. merle , which mainly differs in the aforementioned structure of the clypeal and labral margins and coloration of the upper frons. See also remarks-section of A. merle .

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