Notes on the Brazilian Brachycyrtus Kriechbaumer species (Hymenoptera, Ichneumonidae Brachycyrtinae)

Abstract

Brachycyrtus Kriechbaumer is the single genus of Brachycyrtinae Ichneumonidae subfamily, distributed through the tropics, but a few species can be found in the Neartic and Paleartic regions (Gauld and Ward, 2000). As far as is known, brachycyrtines are idiobionts ectoparasitoids of cocooned pupae and prepupae of Chrysopidae (Neuroptera), but biological information is very scarce. Previously this group was known to belong to the Labeninae subfamily, but it was removed and elevated to sub-familial rank by Wahl (1993). Porter (1998) elevated Pedunculus Townes, 1969 to subfamily rank but later Gauld and Ward (2000) placed this genus with Adelphion and Monganella in the Pedunculinae subfamily and Brachycyrtus in Brachycyrtinae. Only four among fifteen described species were recorded from Brazil:

“…Brachycyrtus Kriechbaumer, 1880 (Hymenoptera: Ichneumonidae: Brachycyrtinae) is cosmopolitan with half of the known species found in the Neotropical region where ~ 10 species are known (Gauld & Ward 2000;Onody et al 2009). However, some species are widely distributed in the New World (e.g.…”

“…3 Current known distribution. Brazil, Costa Rica, Mexico, Panamá, Suriname, Trinidad & Tobago and Venezuela (Gauld & Ward 2000;Onody. et al 2009;Collantes 2011;González-Moreno & Bordera 2011;Yu et al 2016;Fernandes et al 2020a;Fernandes et al 2020b).…”

First record of Labena striata Townes and Townes, 1966 (Hymenoptera, Ichneumonidae, Labeninae) from Colombia

“…The host of this species is unknown. Recently (Loffredo and Penteado-Dias, 2008 a, b;Onody and Penteado-Dias, 2006;Onody et al, 2009;Penteado-Dias and Ramiro, 2009) other Ichneumonidea species from the Neotropical region have been studied and figured.…”
