- Abstract
Background The black palm weevil, Rhynchophorus palmarum (Linnaeus, 1758) (Coleoptera: Curculionidae) is consid‑ ered the most important palm pest in the Americas. In the State of Bahia, Brazil, it is parasitized by tachinid fies (Dip‑ tera: Tachinidae). During 2019–2020, larvae and pupae of R. palmarum were collected from African oil palms (Elaeis guineensis Jacq.) in the municipalities of Jaguaripe and Taperoá, Bahia State, Brazil. Puparia and adult tachinids of two apparent morphospecies, with considerable diferences in body size, were obtained from the R. palmarum immatures, which led to initially assume that we had collected two diferent tachinid species. Results Morphological identifcation as well as COI gene sequencing showed that the two apparent morphospecies belong to a single taxonomic species, Billaea rhynchophorae (Blanchard, 1937) (Diptera: Tachinidae). Conclusions Occurrence of intraspecifc size variability in B. rhynchophorae was reported, as well as performed the frst genetic sequencing for this species. The reason of the size variation could not be determined but some possible causes and implications are discussed.
