Key to species of Barycnellus

1. Fore wing with 2m-cu vein postfurcal ( Fig. 14 View FIGURES 10–15 ). Head, in dorsal view, weakly transverse ( Fig. 67 View FIGURES 65–71 ). Antennae entirely orangebrown or brown, with 21–23 flagellomeres ( Fig. 65 View FIGURES 65–71 ). Ovipositor very short, with apex very thin and strongly upcurved ( Fig. 68 View FIGURES 65–71 ), its sheath about 0.35× as long as hind tibia............................................. B. cuvierensis sp. nov.

- Fore wing with 2m-cu vein antefurcal or interstitial, sometimes vein is virtually absent ( Fig. 12, 13, 15 View FIGURES 10–15 , 16 View FIGURES 16–20 ). Head, in dorsal view, strongly transverse. Antennae dark brown or blackish, with 14–22 flagellomeres. Ovipositor weakly upcurved to almost straight ( Figs 64 View FIGURES 59–64 , 75 View FIGURES 72–79 , 81 View FIGURES 80–87 ), its sheath 1.5–1.6× longer than hind tibia.............................................. 2

2. Head, in lateral view, with antennae inserted well below level of centre of head, and eyes strongly displaced ventrally ( Figs 63 View FIGURES 59–64 , 78 View FIGURES 72–79 ). Flagellum short and thick, usually slightly clavate, with 14–18 flagellomeres ( Figs 61 View FIGURES 59–64 , 79 View FIGURES 72–79 ). Hind leg robust, with femur 2.7–3.2× as long as broad ( Fig. 80 View FIGURES 80–87 )........................................................................ 3

- Head, in lateral view, with antennae inserted at, or slightly below level of centre of head, and eyes less displaced ventrally ( Figs 60 View FIGURES 59–64 , 71 View FIGURES 65–71 ).
