(Hymenoptera, Braconidae, Microgastrinae), a new Indo-Australian genus and one new species from VietnamZookeys309201520155248910210.3897/zookeys.524.6158 Pseudofornicia http://zoobank.org/60B6A212-2344-493B-9168-F4E277EA8977 van Achterberggen. n.Figs 1, 2–10, 11, 12–20, 21, 22–30Etymology.

The specific name is derived from “pseudos” (Greek for “fallacy”) and the generic name Fornicia Brullé, because it is similar to that genus. Gender: feminine.

Distribution.

Indo-Australian.

Biology.

Unknown, but the species of the very similar genus Fornicia are koinobiont endoparasitoids of limacodid caterpillars (Yu et al. 2012).

Comments.

The genus will run in the key to world genera of Microgastrinae by Mason (1981) to the genus Fornicia Brullé. The new genus can be separated as follows:

1Third tergite 1.1–1.6 × as long as second tergite medially and flattened in lateral view; first tergite movably joined to second tergite; second tergite with wide and anteriorly widened medial area; second suture of metasoma curved and together with lateral grooves of medial area more or less X-shaped; head 0.8–1.0 × as wide as mesoscutum; prepectal carina absent; fourth-sixth tergites more or less sclerotized; scapus moderately oblique apicallyPseudofornicia van Achterberg, gen. n.
–Third tergite 0.5–0.9 × as long as second tergite medially and curved in lateral view; first tergite immovably joined to second tergite; second tergite with narrow and anteriorly parallel-sided medial area; second suture of metasoma straight and not connected to lateral grooves of medial area and not X-shaped; head 0.7–0.8 × as wide as mesoscutum; prepectal carina present behind fore coxa; fourth-sixth tergites mainly membranous; scapus strongly oblique apicallyFornicia Brullé
