Genus Nyereria Mason  (Mason 1981)

Pronotum with both dorsal and ventral grooves. Propodeum usually rugulose with a more or less complete median longitudinal carina. Fore wing with areolet open (r –m absent), hind wing with vannal lobe regularly convex and hairy along the margin. Tergum 1 longer than wide, parallel-sided to obviously wider apically. Tergum 2 transverse, not more than about twice as wide as long. Tergum 2 with a raised central area delimited by a pair of deep, usually crenulate, longitudinal grooves, the area narrowed posteriorly, parallel-sided or barrel-shaped but never wider than long, its base never wider than apex of tergum 1. Tergum 3 as long or slightly longer than tergum 2. Hypopygium short, without creases. Ovipositor short, thick and tapered near its half-length, the sheaths with hairs clustered near the apex.

This is a small genus of about 20 known species, parasitizing macrolepidoptera. It was originally described as closely related to Cotesia  due to the propodeal sculpture and the relative sizes of the terga 1–3, though it was considered as a distinct genus because of the peculiar structure of tergum 2 (Mason 1981). Nyereria  was thereafter ranked as a subgenus of Protapanteles  in a revision of Mason’s genera based on European fauna (Van Achterberg 2002), although there are no Nyereria  recorded in Europe. The specimens collected in Reunion match Mason’s description, they are more morphologically related to Cotesia  than to Protapanteles  . Nyereria  is therefore considered here as a valid genus, with two new species described.
