Gnamptodon
Haliday, 1833
Gnamptodon is a of small braconid wasps in the Telengaiinae. Members are minute , with body lengths around 1.3 mm and fore wing lengths of approximately 1.5 mm. The genus has been documented from both Palearctic and Neotropical regions, with recent descriptions extending its known distribution to Brazil. are distinguished by subtle morphological differences in tergite , such as striated versus smooth second tergites.

Identification
within Gnamptodon are differentiated by tergite patterns; for example, G. ayri possesses a striated second while G. novateutonicus has a smooth second tergum. Minute body size (approximately 1.3 mm) and reduced wing venation typical of Telengaiinae are characteristic. Males are unknown for some species, limiting identification resources.
Habitat
Neotropical have been collected in Cerrado and Atlantic Forest biomes in Brazil using . Palearctic records (Denmark, Norway, Sweden) suggest broader , though specific habitat associations in these regions are not documented.
Distribution
Brazil (São Paulo and Minas Gerais states: São Carlos, Assis, Jacutinga, Ribeirão Grande, Itatiaia); Denmark; Norway; Sweden. The spans Palearctic and Neotropical regions.
Host Associations
- Nepticulidae - probable association inferred from Telengaiinae, not directly confirmed for Gnamptodon

- Heliozelidae - probable association inferred from Telengaiinae, not directly confirmed for Gnamptodon
Behavior
Has been observed as a koinobiont of leaf-mining Lepidoptera, based on -level characterization. Whether are endo- or ectoparasitoids remains unknown.

Taxonomic note
The was historically placed in different classifications but is currently recognized in Telengaiinae. The subfamily is characterized by reduced wing venation and association with concealed Lepidoptera .
Research gaps
records are lacking at the level; all host associations are inferred from -level data. Male specimens remain unknown for recently described Neotropical .
