Odontobracon
Cameron, 1887
Odontobracon is a of in the Braconidae, established by Cameron in 1887. Members of this genus are part of the diverse ichneumonoid wasp fauna, characterized by their role as parasitoids of other insects. The genus is represented by very few observations in biodiversity databases, suggesting it is either rare, poorly sampled, or taxonomically cryptic. Braconid wasps in this group generally possess the family-typical features of reduced wing venation and larval development inside or on insects.

Identification
Odontobracon can be distinguished from other braconid by the combination of: with distinct teeth (reflected in the genus name 'Odonto-', meaning tooth), presence of a distinct propodeal areola, and characteristic wing venation patterns including reduced or absent 2m-cu. The genus is morphologically allied to other non-cyclostome braconids but lacks the diagnostic features of the more speciose genera such as Aphidius or Diachasmimorpha. Accurate identification to level requires examination of microscopic characters including ovipositor length, segmentation, and propodeal sculpturing.

Distribution
The has been recorded from the Neotropical and Oriental regions based on specimen records and taxonomic descriptions. Specific country records are sparse in available databases, with most documentation coming from historical taxonomic literature rather than modern survey work.
Ecological Role
As with other Braconidae, in Odontobracon function as , contributing to the of insect . The specific ranges for Odontobracon species remain poorly documented, though braconids in this morphological group typically attack concealed larvae of Coleoptera or Lepidoptera.
Similar Taxa
- Other non-cyclostome BraconidaeOdontobracon shares general body plan and wing venation reduction with many braconid , but differs in mandibular and propodeal structure.
- ChelonusBoth have reduced wing venation, but Chelonus possess a characteristic forewing with closed 1+2R1 and different mandibular structure.
