The parasitic wasp genus Hecabolus (Hymenoptera: Braconidae: Doryctinae), with the description of a new species from Mexico

The doryctine wasp genus Hecabolus Curtis and its type species, H. sulcatus Curtis, are redescribed. A new species from Mexico, H. mexicanus sp. nov., is described and illustrated. The new species is distinguished from H. sulcatus and the other known species of the genus, H. costaricensis Marsh, in having a narrower pterostigma, longer discoidal (discal) cell, basal (1M) and recurrent (m-cu) veins diverging posteriorly, fi rst abscissa of mediocubital (M+CU) vein of hind wing as long as the second abscissa (1M), and fi rst metasomal tergite with a very small dorsope. A key for identifi cation of the 3 known species of Hecabolus is provided
