Trisecodes is a genus of parasitic chalcid wasps of the family Systasidae.[2] The genus was originally placed in Eulophidae, based on a number of morphological features,[1] but molecular evidence suggests that the genus is more closely related to Systasis and Semiotellus.[3] The type species (Trisecodes agromyzae) is a parasitoid of a range of Agromyzid leaf-mining flies.

There are two known species:

  • Trisecodes agromyzae from Belize, Costa Rica and Guadeloupe;[1][4] and
  • Trisecodes africanum from Cameroon, Guinea and Uganda.[5][4]

Description

These are small (0.6-0.85 mm long), dark wasps. Their tarsi have only three segments. Each antenna has three short funicular segments and a clava with two segments.[5]
