Abstract

The cosmopolitan subfamily Blacinae Foerster (Braconidae) is revised with special reference to the Oriental and Australian species. Two new genera are described from Chile: Chalarope and Grypokeros. All known species are keyed, 53 new species are described and fully illustrated, seven new combinations, and five new synonyms are proposed. Lectotypes are designated for eight species. A cladistic analysis of the relationships between the (sub)genera of the subfamily is given and a cladogram is presented.

  • Dec 2023
The genus Bitomus Szepligeti, 1910 (Hymenoptera: Braconidae: Opiinae) is known to parasitize in mining flies (Diptera: Agromyzidae), of which four species are recorded in Korea. Bitomus was revised by Fischer (1987, 1994) and recently treated by Papp (1978, 1981) in Korea. Bitomus is distinguished from other genera by the immovably joined second-third or fourth metasomal tergites, forming a carapace. In this study, Bitomus indicus is recognized for the first time in Korea. This study provides a diagnosis, description, distribution, and diagnostic illustrations.

... The subtribe Spinariina van Achterberg, 1988 of the tribe Rogadini Foerster, 1863 is defined by the presence of a metasomal carapace or spines on the propodeum or pronotum and includes the genera Spinaria Brullé, 1846, Batotheca Enderlein, 1905, Batothecoides Watanabe, 1958, Conspinaria Schulz, 1906, Cornutorogas Chen, Belokobylskij, van Achterberg &Whitfield, 2004 andSpinariella Szépligeti, 1906, (see van Achterberg, 2007). As shown by Quicke et al. (2021) the subtribe Spinariina is sister to the subtribe Rogadina, with the latter lacking the elongate pronotum, the metasomal carapace and the large spines on the body, but having a smooth medio-basal area at the second metasomal tergite. ...
