Typhoctes williamsi
Typhoctes williamsi is a of in the Chyphotidae, a small family of stinging wasps within the order Hymenoptera. The Typhoctes contains only two described species, with T. williamsi being one of them. Members of Chyphotidae are poorly studied and rarely encountered, with most information about the family coming from scattered collection records rather than systematic research. The species is known from extremely few observations.

Identification
Chyphotidae are small, typically 3–7 mm in length, with compact bodies and reduced wing venation. They can be distinguished from other small wasps by the combination of: a pronotum that extends backward to the tegulae (wing bases), short with 10–12 flagellomeres, and a metasoma that is broadly attached to the mesosoma without a narrow petiole. Typhoctes specifically have distinctive mandibular structure and clypeal , though species-level identification requires examination of microscopic characters.
Similar Taxa
- PlumariidaePlumariidae is the only other in the superfamily Plumarioidea alongside Chyphotidae. Both families share reduced wing venation and similar body plans, but Plumariidae have more elongated bodies and different antennal structure.
- Mutillidae (velvet ants)Female velvet ants are wingless and can resemble small chyphotid wasps in general appearance. Mutillidae have dense, velvety and a more constricted waist between mesosoma and metasoma, unlike the broad attachment in Chyphotidae.
- BethylidaeBethylid are similar in size and general habitus to chyphotids. They can be distinguished by their typically elbowed and different wing venation patterns, with bethylids having a closed marginal in the forewing.

Taxonomic obscurity
Chyphotidae is one of the least known of Hymenoptera, with fewer than 20 described worldwide. The family was historically placed in various superfamilies before molecular confirmed its placement in Plumarioidea. Most species are known from single specimens or very few collections, and no comprehensive biological studies exist for any member of the family.
Collection rarity
The iNaturalist database contains only one observation for T. williamsi, reflecting the extreme rarity of encounters with this . This is typical for the —chyphotids are not attracted to standard insect collecting methods like or light traps in large numbers, and their small size makes them easy to overlook in general surveys.
