Abstract

ABSTRACT A new species of Diolcogaster (Ashmead, 1900) (Hymenoptera: Braconidae) is described and illustrated. Additionally, a key to all New World species formally published of the xanthaspis species-group (to which the new species belongs) is provided. The solitary larval parasitoid Diolcogaster flammeus sp. nov. was collected in Viçosa, Minas Gerais State, Brazil. This natural enemy was reared from caterpillars of Agaraea minuta (Schaus, 1892) (Lepidoptera: Erebidae) feeding on plants of spiked spiralflag ginger, Costus spicatus (Jacq.) Sw. and ginger spiral, Costus spiralis (Jacq.) Roscoe var. spiralis (Costaceae). The fauna of the xanthaspis group in the New World included just three published species prior to this publication. Diolcogaster flammeus sp. nov. is the only yellow-orange species of the xanthaspis group recorded in the New World thus far.

DNA barcoding and the taxonomy of Microgastrinae wasps (Hymenoptera, Braconidae): impacts after 8 years and nearly 20 000 sequences.

M. Alex Smith, J L Fernandez-Triana, E. Eveleigh … (2013)

Microgastrine wasps are among the most species-rich and numerous parasitoids of caterpillars (Lepidoptera). They are often host-specific and thus are extensively used in biological control efforts and figure prominently in trophic webs. However, their extraordinary diversity coupled with the occurrence of many cryptic species produces a significant taxonomic impediment. We present and release the results of 8 years (2004-2011) of DNA barcoding microgastrine wasps. Currently they are the best represented group of parasitoid Hymenoptera in the Barcode of Life Data System (BOLD), a massive barcode storage and analysis data management site for the International Barcoding of Life (iBOL) program. There are records from more than 20 000 specimens from 75 countries, including 50 genera (90% of the known total) and more than 1700 species (as indicated by Barcode Index Numbers and 2% MOTU). We briefly discuss the importance of this DNA data set and its collateral information for future research in: (1) discovery of cryptic species and description of new taxa; (2) estimating species numbers in biodiversity inventories; (3) clarification of generic boundaries; (4) biological control programmes; (5) molecular studies of host-parasitoid biology and ecology; (6) evaluation of shifts in species distribution and phenology; and (7) fostering collaboration at national, regional and world levels. The integration of DNA barcoding with traditional morphology-based taxonomy, host records, and other data has substantially improved the accuracy of microgastrine wasp identifications and will significantly accelerate further studies on this group of parasitoids. © 2012 Blackwell Publishing Ltd.
