Arpactophilus fagauvea View in CoL sp. nov.
( Figs. 51–52 View FIGURES 47 – 52 )
Diagnosis. Arpactophilus fagauvea is the only New Caledonian species in the genus with the combination of a longitudinally wrinkled frons ( Fig. 51 View FIGURES 47 – 52 ), two submarginal cells in the forewing, a reddish-brown metasoma and no bulge on sternum II ( Fig. 52 View FIGURES 47 – 52 , and as in Fig. 1 View FIGURES 1 – 4 ). Another distinctive feature is the medially strongly projecting apical margin of the clypeus with a medioapically straight margin ( Fig. 51 View FIGURES 47 – 52 ).
Description. FEMALE: Total length 4.4–4.5 mm, mean = 4.4 mm; forewing length 2.4–2.5 mm, mean = 2.4 mm.
Body black and reddish-brown, with areas of yellow and brown. Yellow: mandible laterally at base; palpi; scape; pedicel; tegula; trochanters; femora apically; tibiae, except weakly-defined apical area on metatibia; tarsi. Brown: most of mandible; flagellum; anterior pronotal margin; pronotal lobe; coxae; most of femora; weaklydefined apical area on metatibia. Metasoma reddish-brown ( Fig. 52 View FIGURES 47 – 52 ). Wings hyaline; pterostigma light brown.
Head about 1.3 × as long as wide in frontal view. Apical margin of clypeus strongly projecting medially, medioapical margin straight (not incised as is common in other species) ( Fig. 51 View FIGURES 47 – 52 ). Apical margin of labrum medially projecting. Ventral mandibular tooth about ¼–1/5 of total mandibular length, not reaching opposite mandibular base. Palpal formula 4:3. Frons imbricate, also longitudinally costate, with short setae. Frontal carina present from median ocellus to midlength of clypeus, forming small point at basal clypeal margin. Scape 4 × as long as wide. Median ocellus anterior of tangent between upper posterior orbits of compound eyes, lateral ocelli on tangent. 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, not angulate.
Mesosoma about 1.8 × as long as wide in dorsal view. Propodeum about 0.8 × as long as wide in dorsal view. Mesosoma imbricate ( Fig. 52 View FIGURES 47 – 52 ), except propodeum; lateral surface of propodeum transversely carinulate; dorsal surface of propodeum reticulate with transverse longitudinal carinae (similar to pattern in Fig. 20 View FIGURES 16 – 22 ). Slightly pitted sulcus present posterior to fine mesoscuto-mesoscutellar sulcus. Hypersternal sulcus absent. Metafemur 2.4 × as long as wide. Metatibia with a weakly-defined, light brown colored apical area. Pretarsal claws without teeth. Forewing with two submarginal cells; anterior border of submarginal cell II much shorter than posterior border, almost triangular in shape. Hind wing with five distal hamuli.
Metasoma polished, punctation on basal segments sparse, on apical segments denser ( Fig. 52 View FIGURES 47 – 52 ). Metasomal sternum II without bulge (as in Fig. 1 View FIGURES 1 – 4 ). Pygidium with broad row of silk setae.
MALE: Difference from female aside from genitalic structures: mandible yellow; metatibia without differently colored area apically. Metasomal sternum VIII narrow.
Remarks. Arpactophilus fagauvea can be distinguished from all other species with a reddish metasoma by its longitudinally costate frons. Arpactophilus futuna is similar in body size and coloration, but differs in the sculpture of the frons and can also easily be separated by the thin, acutely rounded genal spine ( Fig. 13 View FIGURES 10 – 15 ), which is not present in A. fagauvea .

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