Trigonalidae
Guides
Lycogaster
Lycogaster is a genus of parasitoid wasps in the family Trigonalidae, first described by Shuckard in 1841. Members of this genus are hyperparasitoids, meaning they parasitize other parasitoids. The genus was first recorded from Vietnam in 2025 based on specimens of L. flavonigrata, expanding its known distribution beyond China.
Orthogonalys
Orthogonalys is a genus of trigonalid wasps comprising hyperparasitoid species. At least one species, Orthogonalys pulchella, employs a distinctive 'scattershot' approach to host location, a notable behavioral adaptation among parasitoid wasps. The genus belongs to the family Trigonalidae, a group known for complex life histories involving secondary parasitism.
Orthogonalys pulchella
Orthogonalys pulchella is a species of hyperparasitoid wasp in the family Trigonalidae. This species is part of a unique guild of parasitoids that target the larvae of other parasitoid wasps rather than primary hosts. The species was described by Cresson and has been documented in parts of North America.
Taeniogonalos gundlachii
Taeniogonalos gundlachii is a species of hyperparasitoid wasp in the family Trigonalidae. It has been documented as a hyperparasitoid of the giant silkmoth Hyalophora cecropia. The species is recorded from eastern Canada, with observations in New Brunswick, Nova Scotia, Ontario, and Quebec. As a member of Trigonalidae, it likely exhibits the family's characteristic biology of hyperparasitism, though direct observations of its complete life history remain limited.
