Redescription of Mononeuron duguetiae Fischer (Braconidae, Doryctinae), a gall associated species on Duguetia furfuracea (St. Hil.) (Annonaceae)

We redescribe the poorly known, gall associated doryctine wasp Mononeuron duguetiae Fischer (Braconidae) based on museum and recently collected material. This species shares various morphological features with the members of the also gall associated Allorhogas Gahan, suggesting their close relationship. A Bayesian phylogenetic analysis using mitochondrial (COI) and nuclear (28S) markers recovered M. duguetiae within a clade with another five gall associated doryctine genera + Heterospilus Haliday. Surprisingly, M. duguetiae was recovered, though with low support, as the sister taxon of a Monitoriella Hedqvist + Labania Hedqvist clade, and not closely related to Allorhogas. Information is provided about the galls on Duguetia furfuracea (St. Hil.) (Annonaceae) where the specimens of M. duguetiae were reared.
