Altitudinal range. From coastal to inland valley ecosystems ( 0– 200 m .a.s.l.). Biology and notes. Eosalpingogaster nigriventris is here reported from Chile for the first time. This species is morphologically similar to E. conopida . The species Ethelurgus rufipes (Brèthes) (Ichneumonidae) , Prosaspicera cesarina (Brèthes) (Figitidae) and Trichomalus polviventris Brèthes have been mentioned as parasitoids of this species by Silva et al. (1968) . It has been described that E. nigriventris prey on Coccidae and Diaspididae (Lizer y Trelles 1939 ; Knutson 1971 ). Conservation status. DD; AOO = 2 km 2 and one locality (or subpopulation).
