Mexican cardiochiline genera (Hymenoptera: Braconidae), including a preliminary assessment of species-groups in Toxoneuron Say and Retusigaster Dangerfield, Austin and Whitfield

Two new reared species of Heteropteron Brullé (Hymenoptera, Braconidae, Cardiochilinae) from northwest Costa Rica, with the first definitive host records for the genus

“…The remaining three genera were still considered as distinct as recently as Whitfield and Dangerfield (1997), but two years later Dangerfield et al (1999) synonymized all three with Heteropteron as the senior synonym. Shortly afterward Mercado and Wharton (2003) pulled Wesmaelella (including Psilophthalmus) out of synonymy with Heteropteron, an arrangement agreed with by Papp (2014), with some reservations still due to confusion in the interpretation of some types. Due to museum loan limitations at the relevant museums, it has never been possible to compare all the types with one another simultaneously, but the situation has been clarified considerably in the last 20 years, and Papp's conclusions are adopted here.…”

Two new species and distribution records for the genus Bohayella Belokobylskij, 1987 from Costa Rica (Hymenoptera, Braconidae, Cardiochilinae)

“…Cardiochilinae is a subfamily of Braconidae, containing 17 genera and 220+ species (Yu et al 2012;Kang et al 2020). Bohayella Belokobylskij, 1987 (Belokobylskij 1987) is an unusual genus of the subfamily, with nine previously described species that are only known from the Old World, including Afrotropical, Australasian, Oriental, and southern central Palearctic regions (Dangerfield et al 1999;Mercado and Wharton 2003;Yu et al 2012). Among the nine Old World species of Bohayella, two species, B. adina (Wilkinson, 1930) and B. exiguurus (Huddleston & Walker, 1988), have rearing records (Huddleston and Walker 1988).…”

“…Cardiochiles nigricans Mao, 1949(Mao 1949 was transferred into Bohayella by Dangerfield et al (1999) and recorded as the first species of Bohayella in the New World. Mercado and Wharton (2003) transferred the species into Toxoneuron Say, 1836 because the first metasomal tergite (T1) of the species is different from T1 of other members of Bohayella. Subsequently, members of Bohayella have been restricted to the Old World and new species of the genus have not been reported from the New World.…”

Revision of Iranian Schoenlandella Cameron, 1905 (Hymenoptera, Braconidae, Cardiochilinae) with descriptions of two new species from Hormozgan province

“…The taxonomic status of Schoenlandella was discussed by Whitfield and Dangerfield (1997), Dangerfield et al (1999), Mercado and Wharton (2003), Papp (2014), and Kang et al (in prep.). Kang et al (in prep.…”
