Vespicula is a genus of venomous ray-finned fishes, waspfishes belonging to the subfamily Tetraroginae, which is classified as part of the family Scorpaenidae, the scorpionfishes and their relatives.

Although FishBase recognises this genus as valid, other authorities, such as the Catalog of Fishes regard it as a synonym of Trichosomus.

More recently A. depressifrons was placed in the monotypic genus Neovespicula, A. dracaena in Pseudovespicula, and A. trachinoides into Trichosomus with A. bottae and A. gogorzae being regarded as junior synonyms of Trichosomus trachinoides.

This left P. cypho and A. zollingeri in Vespicula but these two species share a number of characteristics with P. dracaena so they were placed in an expanded Pseudovespicula.

[5] The genus name Vespicula is a diminutive of Vespa, meaning wasp, i.e. a waspfish.
