Resumen:
The gregarious species of Apanteles that attack cactus-feeding phycitine moths (Lepidoptera : Pyralidae) from
Argentina are identified usingDNAbarcodes and morphological data. Sequences of specimens from 10 different populations
were generated. Corrected genetic divergences showed two clusters of specimens separated by COI divergences higher than
6%. Our morphological examinations were congruent with the molecular evidence and therefore two species were
confidently identified: Apanteles alexanderi Brèthes and a new species, Apanteles opuntiarum Martínez & Berta, sp.
nov., which we describe and illustrate. Despite these two taxa being considered to represent a single polyphagous species for
at least 50 years, they can be easily distinguished by the length of their ovipositor sheaths.Akey to the species of microgastrine
parasitoids of cactus-feeding Lepidoptera in South America is provided. The recognition of the new species reveals a
narrower host range for the species involved in this system, making it necessary to re-evaluate their potential as biocontrol
agents of the prickly pear moth.
