Host data. Gregarious parasitoid of Ormetica sicilia ( Erebidae , Arctiinae ) feeding on leaves of Inga vera ( Fabaceae ); 6 wasps eclosed 21/viii/1999 and 4 eclosed 23/viii/1999 from 10 beige wasp cocoons spun next to the cadaver inside the moth cocoon.

Caterpillar and holotype voucher codes. 03-SRNP-9821, DHJPAR0029331.

Paratypes.

As recorded for each of the vouchers below, all are hairy, medium-sized Arctiinae ( Erebidae ) caterpillars. All 15 caterpillar cocoons have gregarious parasitoids that spin their white cocoons inside the caterpillar cocoon after emerging from the prepupal caterpillar. Hosts = Lophocampa modestaDHJ01, Lophocampa maroniensis , Ormetica ataenia , Ormetica sicilia , Viviennea tegyra .
