Barycnellus conlisus Khalaim & Ward , sp. nov.

( Figs 13 View FIGURES 10–15 , 24 View FIGURES 21–26 , 61–64 View FIGURES 59–64 )

Comparison. Barycnellus conlisus is readily distinguished from other species of the genus by the head strongly flattened, subrectangular in lateral view ( Fig. 63 View FIGURES 59–64 ), and the mesosoma very strongly compressed laterally ( Fig. 62 View FIGURES 59–64 ).

Description. Female. Body length 2.5 mm. Fore wing length 2.6 mm.

Head mostly smooth and shining, except for granulate and dull face ( Figs 62, 63 View FIGURES 59–64 ). Head strongly flattened frontally, almost rectangular ( Fig. 63 View FIGURES 59–64 ). Head in lateral view about 1.9× as high (from lower margin of clypeus to top of head) as broad, with antennae inserted well below level of centre of head ( Fig. 63 View FIGURES 59–64 ). Clypeus very narrow. Malar space less than half as long as basal mandibular width. Flagellum short and thick, moderately clavate, with 14–16 shortened flagellomeres (14 in holotype) ( Fig. 61 View FIGURES 59–64 ).

Mesoscutum and mesopleuron smooth and shining ( Fig. 63 View FIGURES 59–64 ). Mesosoma very strongly compressed laterally, with mesoscutum, in dorsal view, 0.55× as broad as head ( Fig. 62 View FIGURES 59–64 ). Notaulus present, reaching 0.2 along mesoscutum. Foveate groove thin and short, weakly oblique, in centre of mesopleuron ( Fig. 63 View FIGURES 59–64 ). Propodeum with basal median furrow with greater granulation than on dorsolateral areas of propodeum, about 0.3× as long as apical area. Propodeum virtually ecarinate, with only transverse carina discernible medially. Apical area narrow.

Fore wing ( Fig. 13 View FIGURES 10–15 ) with vein R1 weak, indistinct, not reaching apex of the wing. Veins Rs and Rs+2 r meeting at obtuse angle. Vein 2m-cu antefurcal, entirely absent or discernible only posteriorly. Vein Cu1b intercepted near its centre. Legs robust, hind femur 2.7–3.2× as long as broad (3.2× in holotype).

Metasoma slightly compressed. First tergite, petiole dorsally finely granulate; postpetiole posteriorly smooth. Second tergite 1.8× as long as anteriorly broad. Thyridial depression twice as long as broad, or longer. Ovipositor weakly and evenly upcurved, with sharp dorsal subapical notch ( Fig. 64 View FIGURES 59–64 ); sheath 1.6× as long as hind tibia.

Head, mesosoma and first tergite brown to brownish black. Clypeus yellowish. Mandible (teeth darkened), palpi, scape and pedicel of antenna, base of flagellum and tegula pale. Pterostigma brown. Fore and mid legs yellow; hind leg brownish with trochanters yellow. Metasoma behind first tergite yellowish brown ventrally to brown and dark brown dorsally.

Male. Unknown.

Molecular data. BOLD BIN: AAZ9215.

Etymology. From the Latin conlisus (crushed, flattened) because of flattened frontally head and strongly compressed laterally mesosoma.
