Review of the genus Cassidibracon Quicke, 1987 and related taxa of the Plesiobracon group of genera (Hymenoptera: Braconidae: Braconinae)

Abstract

Members of several genera of the Plesiobracon genus-group are reclassifed. A new species, Cassidibracon vannoorti sp. n. from South Africa, and two new genera, Isomerosoma gen. n. (type species Bracon subacaudatus Granger, 1949) and Reticulotergus gen. n. (type species Cassidibracon indicus Narendran et Rema, 1994), are described. Pseudochivinia Long et van Achterberg, 2023, stat. n. recently described as a subgenus of Bracon Fabricius, 1804 is considered a valid genus. The genus Triaspidogastra Granger, 1949, syn. n. is synonymised with Esenga Cameron, 1906. The new replacement name Bracon vitobiasi Long et van Achterberg, nom. n. is proposed for the junior primary homonym Bracon tobiasi Long et van Achterberg, 2023 (nec Papp, 1965). The following new combinations are given: Esenga lutea (Granger, 1949), comb. n. (from Triaspidogastra), Esenga testacea (Granger, 1949), comb. n. (from Triaspidogastra), Lyricibracon nigerianus (Quicke, 1988), comb. n. (from Rugosibracon Quicke, 1988), Pseudochivinia vitobiasi (Long et van Achterberg, 2023), comb. n. (from Bracon), Sculptolobus repens (Gupta, 2014), comb. n. (from Cassidibracon Quicke, 1987), Scutibracon gracillariae (Quicke, 2012), comb. n. (from Cassidibracon), Scutibracon malabaricus (Narendran, 1994), comb. n. (from Cassidibracon), Scutibracon sumodani (Narendran et Madhavikutty, 1994), comb. n. (from Cassidibracon), and Trigastrotheca notata (Szépligeti, 1914), comb. n. (from Habrobracon Ashmead, 1895). Lectotypes are designated for Bracon subacaudatus Granger, 1949 and Triaspidogastra lutea Granger, 1949
