Two new reared species of Heteropteron Brullé (Hymenoptera, Braconidae, Cardiochilinae) from northwest Costa Rica, with the first definitive host records for the genus

Abstract

Two new Costa Rican species of the braconid parasitoid wasp subfamily Cardiochilinae, Heteropteron kidonoi Dabek & Whitfield and Heteropteron hasagawai Dabek & Whitfield, are described and illustrated from dry forest in the Area de Conservacion Guanacastae, along with data on rearing from their hosts. Heteropteron kidonoi is a solitary endoparasitoid of Stenoma cathosiota (Lepidoptera: Depressariidae) on

Roupala montana (Proteaceae), while H. hasagawai is a solitary endoparasitoid of Carthara abrupta (Lepi- doptera: Pyralidae) on the same host plant, but typically at slightly higher elevation localities. Diagnostic

characters are provided to distinguish these two new species from each other, and also from the three previously decsribed species of Heteropteron. Heteropteron kidonoi and H. hasagawai are the first species of Heteropteron to have any host data, and also are the first to be reported in Costa Rica.
