Arpactophilus haveke View in CoL sp. nov.
( Figs. 59–60 View FIGURES 59 – 64 )
Diagnosis. Arpactophilus haveke is the only New Caledonian species in the genus that has a stalked triangular submarginal cell II in the forewing, and particularly when taken in combination with the light reddish-brown metasoma further distinguishes itself from its congeners. Another distinctive feature is the apical margin of thee clypeus which is projecting medially and medioapically forming a point, without a medial incision ( Fig. 59 View FIGURES 59 – 64 ).
Description. FEMALE: Total length 3.8 mm; forewing length 2.3 mm.
Body black, with areas of light yellow and light reddish-brown. Light yellow: apical margin of clypeus ( Fig. 59 View FIGURES 59 – 64 ); mandible; palpi; scape in front; pronotal lobe; tegula; coxae apically; trochanters; femora partially; tibiae, except apical area on metatibia; tarsi. Light reddish-brown: posterior of scape; pedicel; flagellum; most of coxae; most of femora; apical area on metatibia; metasoma ( Fig. 60 View FIGURES 59 – 64 ). Wings hyaline; pterostigma light brown. Labrum and anterior pronotal margin not visible.
Head about as long as wide in frontal view. Apical margin of clypeus projecting medially, medioapically forming a point (not incised or with a straight margin as in some other species) ( Fig. 59 View FIGURES 59 – 64 ). Labrum not visible. Ventral mandibular tooth about ¼–1/5 of total mandibular length, not reaching opposite mandibular base. Palpal formula 4:3. Frons imbricate with sparse punctation and short setae. Frontal carina present from median ocellus to apical margin of clypeus. Scape 3.7 × 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 sparse setae, without tubercles, spines, or dorsoventral carina. Hypostomal midventral line faint, not angulate.
Mesosoma about 1.7 × as long as wide in dorsal view. Propodeum about 0.8 × as long as wide in dorsal view. Mesosoma imbricate except on propodeum ( Fig. 60 View FIGURES 59 – 64 ); lateral and dorsal surface of propodeum transversely carinulate; dorsal surface of propodeum also finely reticulate with transverse carinulae apically (similar to pattern in Fig. 20 View FIGURES 16 – 22 ). No groove present posterior to mesoscuto-mesoscutellar sulcus. Hypersternal sulcus absent. Metafemur 2.6 × as long as wide. Metatibia with a light brown area apically. Forewing with two submarginal cells; submarginal cell II triangular, not reaching media but connected to it by a single crossvein (i.e., cell is stalked). Hind wing with four distal hamuli.
Metasoma polished, punctation and associated setae sparse ( Fig. 60 View FIGURES 59 – 64 ). Metasomal sternum II without bulge (as in Fig. 1 View FIGURES 1 – 4 ). Pygidium with narrow row of silk setae.
MALE: Difference from female aside from genitalic structures: yellow marking on clypeus larger; yellow markings present on lower frons and malar space; flagellum yellow; metasoma brown. Metasomal sternum VIII neither broadened nor narrowed.
Remarks. Arpactophilus haveke can easily be distinguished from the other species with a reddish metasoma by its stalked second submarginal cell. The only species that has a similarly triangular (but not stalked) second submarginal cell is A. tiri , which has a much more slender body form ( Fig. 102 View FIGURES 101 – 106 ).

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