New records of the genus Iporhogas Granger (Hymenoptera, Braconidae, Rogadinae) from Vietnam, with description of four new species

Abstract

The genus Iporhogas Granger, 1949 (Braconidae: Rogadinae) is recorded for the first time for Vietnam. Four new species of the genus Iporhogas, viz. Iporhogas albilateralis sp. n., I. contrastus sp. n., I. simulatus sp. n. and I. tricoloratus sp. n., from Vietnam are described and illustrated, and additionally, one species, Iporhogas guangxiensis Chen & He, 1997, is newly recorded for Vietnam’s fauna of the family Braconidae. A key to the five Vietnamese species of the genus Iporhogas and a checklist with distributions of the ten species are provided.

A molecular phylogeny of the parasitoid wasp subfamily Rogadinae (Ichneumonoidea: Braconidae) with descriptions of three new genera

“…Indeed, both genera key to Iporhogas in Chen & He (1997). Described species of Iporhogas and Troporhogas are typically rather boldly patterned, often with a bicoloured, black and white metasoma (Long, 2014), and both have curved and either entirely (Troporhogas) or partly (Iporhogas) glabrous hind tibial spurs, and usually conspicuously transversely striate face, frons and occiput. Troporhogas tricolor Cameron, the type species, has a distinct mid-longitudinal carina on the median area of the metanotum, but this character can be variable among species in the genus.…”

“…The principally tropical generic diversity had been rather poorly studied until van Achterberg (1991), Chen & He (1997) and Shaw (1997b) revised the Afrotropical, Chinese and New World genera, respectively. These works collectively described six new genera and provided a useful genus-level framework, which led to further studies recognizing several more new genera (Chen et al, 2004;Braet & van Achterberg, 2011;, 2015Quicke et al, 2012aQuicke et al, , 2014Butcher & Quicke, 2015a, Sharkey et al, 2021, new species Quicke et al 2012b;Butcher et al 2014;Long, 2014;Butcher & Quicke, 2015b;Sharkey et al 2021) and new host records (Shaw, 2002;Maetô & Arakaki, 2005;Quicke & Shaw, 2005a,b;Quicke et al 2012aQuicke et al , 2012bQuicke et al , 2012cSharkey et al 2021). However, no comprehensive work on the Indo-Australasian genera has been conducted and the number of described Indo-Australasian taxa is almost certainly a gross underestimate of their real numbers.…”
