Dickyyuella argentinensis a tentative new genus and species of Cardiochilinae (Hymenoptera, Braconidae) from the Neotropical region
Dickyyuella Kang & Sharkey, gen. nov. is a novel addition to the microgastroid complex of Braconidae. Taxonomic assignment within this complex posed challenges initially due to the presence of putatively plesiomorphic characters. However, closer examination revealed affiliations with the microgastroid complex, supported by morphological features such as the location of spiracles on the first metasomal tergum and the absence of spiracles on the seventh metasomal tergum. Based on the following two morphological characters, the presence of an inverted Y-shaped groove on the first metasomal tergum and pectinate tarsal claws, Dickyyuella Kang & Sharkey, gen. nov. is tentatively placed within Cardiochilinae Ashmead, 1900 despite uncertainties surrounding phylogenetic relationships. This article provides the diagnosis of Dickyyuella Kang & Sharkey, gen. nov., the description of Dickyyuella argentinensis Kang & Sharkey, sp. nov., and a discussion of the taxonomic placement of the new genus within the microgastroid complex.
