New species of the ‘rare’ generaDentigaster Zettel, 1990 andOdontosphaeropyx Cameron, 1910 (Hymenoptera: Braconidae: Cheloninae)

First record of Odontosphaeropyx Cameron, 1910 from the Oriental Region with description of a new species from Thailand (Hymenoptera, Braconidae, Cheloninae)

“…In the key to Odontosphaeropyx species by Braet et al (2014), which was modified after the one by Zettel (1990), this new species falters at couplet 1 because it has fore wing vein 3RSa longer than r-rs but has the metasoma more than 2.6× longer than wide. The only described species with similar colouration (orange thorax and largely black metasoma with white-banded 2 nd tergite) is O.flavifasciatus Zettel, 1990, which is known from Nigeria (type locality) and Democratic Republic of Congo.…”

“…However, worldwide another 16 genera (including the Adeliini) are known, most with more restricted geographic distributions and often known from only a few species and specimens (Zettel 1990, He et al 1994, Kittel and Austin 2014). The OdontosphaeropyginiZettel 1990 (= PseudophanerotominiZettel 1990, synonymized by Braet et al 2014) are a monotypic tribe with six included species, all in Odontosphaeropyx Cameron, and all from the Afrotropical region (Kittel et al 2016). Here we report the discovery of the first species from outside of Africa and describe a new species of Odontosphaeropyx of Thailand.…”

“…Among these we discovered two specimens of a relatively large-bodied chelonine, with a single clypeal tooth, fore wing vein (RS+M)a arising from vein 1-M well removed from parastigma, forewing vein m-cu joining (RS+M)a basal to 2RS, and with a pair of transverse sutures on the carapace. Initial generic identification based on the known Asian fauna was problematic, so we used the key to world genera and tribes of Zettel (1990) and obtained a clear identification as Odontosphaeropyx which was previously known from six described species, all from sub-Saharan Africa and Madagascar (Braet et al 2014).…”
