Arpactophilus bwatoo View in CoL sp. nov.
( Figs. 33–34 View FIGURES 29 – 34 )
Diagnosis. Arpactophilus bwatoo is the only New Caledonian species in the genus with the combination of a continuous occipital carina ( Fig. 5 View FIGURES 5 – 9 ), two submarginal cells in the forewing, and a half yellow clypeus with a medially projecting apical margin and with a shallow, broad incision ( Fig. 33 View FIGURES 29 – 34 ), and a black metasoma without a bulge on sternum II ( Fig. 34 View FIGURES 29 – 34 , and as in Fig. 1 View FIGURES 1 – 4 ).
Description. FEMALE: Total length 5.5 mm; forewing length 2.8 mm.
Body black, with areas of yellow and brown. Yellow: apical half of clypeus ( Fig. 33 View FIGURES 29 – 34 ); labrum; mandible; palpi; scape in front; coxae apically; trochanters; most of femora; tibiae; tarsi. Brown: posterior of scape; pedicel; flagellum apically; tegula; coxae basally, pro- and mesofemora ventrally ( Fig. 34 View FIGURES 29 – 34 ); fine line on metafemur. Wings hyaline; pterostigma dark brown.
Head about as long as wide in frontal view. Apical margins of clypeus and labrum medially projecting, with shallow, broad incision or concavity ( Fig. 33 View FIGURES 29 – 34 ). Ventral mandibular tooth about ¼–1/5 of total mandibular length, not reaching opposite mandibular base. Palpal formula 4:3. Frons finely costate with sparse punctation and associated setae on upper frons and dense punctation and associated setae on lower frons. Frontal carina present from median ocellus to midlength of clypeus. Scape 4.1 × as long as wide. Ocellar triangle anterior of tangent between upper posterior orbits of compound eyes, lateral ocelli anterior of tangent by less than their diameter. Occipital carina continuous ( Fig. 5 View FIGURES 5 – 9 ). Most of gena polished, with sparse punctation and sparse long 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 0.9 × as long as wide in dorsal view. Mesosoma dorsally imbricate with sparse punctation ( Fig. 34 View FIGURES 29 – 34 ), except dorsal surface of propodeum, laterally colliculate; lateral surface of propodeum imbricate and transversely carinulate; dorsal surface of propodeum coarsely reticulate (similar to pattern in Fig. 18 View FIGURES 16 – 22 ). Pitted sulcus present posterior of fine mesoscuto-mesoscutellar sulcus. Hypersternal sulcus present, simple. Metafemur 3.4 × 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, almost impunctate ( Fig. 34 View FIGURES 29 – 34 ). Metasomal sternum II without bulge (as in Fig. 1 View FIGURES 1 – 4 ). Pygidium with broad row of silk setae apically.
MALE: As in female except genitalic differences. Metasomal sternum VIII narrow.
Remarks. Arpactophilus bwatoo is similar to A. pije and A. jawe in body size and coloration, but can be distinguished by the costate frons ( Fig. 33 View FIGURES 29 – 34 ). The species has a yellow metafemur with small dark brown markings, which differs from the almost completely black metafemur of A. pije and the yellow and whitish-yellow metafemur of A. jawe .

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