Comparison.
Barycnellus conlisus
is readily distinguished from other species of the genus by the head strongly flattened, subrectangular in lateral view (
Fig. 63
), and the mesosoma very strongly compressed laterally (
Fig. 62
).
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
). Head strongly flattened frontally, almost rectangular (
Fig. 63
). 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
). 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
).
Mesoscutum and mesopleuron smooth and shining (
Fig. 63
). Mesosoma very strongly compressed laterally, with mesoscutum, in dorsal view, 0.55× as broad as head (
Fig. 62
). Notaulus present, reaching 0.2 along mesoscutum. Foveate groove thin and short, weakly oblique, in centre of mesopleuron (
Fig. 63
). 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
) 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
); 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.
