Arpactophilus caac View in CoL sp. nov.
( Figs. 20 View FIGURES 16 – 22 , 35–36 View FIGURES 35 – 40 )
Diagnosis. Arpactophilus caac is the only New Caledonian species in the genus with the combination of a black, projecting clypeus with a nearly straight apical margin medially ( Fig. 35 View FIGURES 35 – 40 ), yellow mandible, the frontal carina forming a projecting tip on the basal clypeal margin, a yellowish flagellum about as light or only little darker than the scape, a dorsally-interrupted occipital carina ( Fig. 6 View FIGURES 5 – 9 ), two submarginal cells in the forewing, yellow legs, a flat metasomal sternum II without a bulge (as in Fig. 1 View FIGURES 1 – 4 ), and a dark brown metasoma ( Fig. 36 View FIGURES 35 – 40 ).
Description. FEMALE: Total length 3.0– 3.7 mm, mean = 3.4 mm; forewing length 2.2–2.3 mm, mean = 2.2 mm.
Body black or brown, with areas of yellow. Yellow: mandible; labrum; palpi; scape; pedicel; flagellum (slightly darker towards apex); anterior pronotal margin; pronotal lobe; tegula; legs. Wings hyaline; pterostigma brown.
Head about 0.9 × as long as wide in frontal view. Apical margin of clypeus projecting medially, medioapical margin nearly straight ( Fig. 35 View FIGURES 35 – 40 ). Apical margin of labrum bilobed. 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 imbricate with sparse punctation and long setae. Frontal carina present from median ocellus to upper half of clypeus, forming a distinct point at basal clypeal margin. Scape 3.9 × as long as wide. Ocellar triangle anterior of tangent between upper posterior orbits of compound eyes, lateral ocelli anterior of tangent by approximately their diameter. Occipital carina interrupted dorsally ( Fig. 6 View FIGURES 5 – 9 ). Gena imbricate with sparse punctation and long setae, without tubercles, spines, or dorsoventral carina. Hypostomal midventral line carinate, not angulate.
Mesosoma about 1.7 × as long as wide in dorsal view. Propodeum about 0.9 × as long as wide in dorsal view. Mesosoma imbricate with sparse punctation ( Fig. 36 View FIGURES 35 – 40 ), except posterior part of dorsal surface of propodeum; lateral surface of propodeum also imbricate and transversely carinulate; dorsal surface of propodeum also reticulate medially, lateral and posterior areas of dorsal surface of propodeum transversely carinulate ( Fig. 20 View FIGURES 16 – 22 ). Slightly pitted sulcus present posterior to fine mesoscuto-scutellar sulcus. Hypersternal sulcus represented by fine line. Metafemur 3.0 × 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 slightly shorter than posterior border. Hind wing with five distal hamuli.
Metasoma polished, sparsely punctured ( Fig. 36 View FIGURES 35 – 40 ). Metasomal sternum II without bulge (as in Fig. 1 View FIGURES 1 – 4 ). Pygidium with narrow row of silk setae apically.
MALE: Difference from female aside from genitalic structures: apical half of clypeus yellow. Metasomal sternum VIII neither broadened nor narrowed.
Remarks. Arpactophilus caac is somewhat similar to A. pwaamei , A. kraussi , and A. tayo in the head shape, size and general coloration. Arpactophilus kraussi has a finer sculpture on the propodeal dorsum. Arpactophilus caac can be distinguished from A. tayo easily by the black coxae of the latter. The coarse macro-punctation on the frons of A. pwaamei distinguishes it from A. caac with its fine punctation.
