Abstract

A revised checklist of eight of the twelve known palaearctic species in the subgenus Macroneura of Eupelmus occurring in the Iberian Peninsula, Balearic and Macaronesian islands (Azores, Balearics, Canaries, Madeira) is presented. Records of the distribution in the region of all the revised species are given with new biological notes, including host insects and plants. Eupelmus (Macroneura) seculatus is a new record for the Canary Islands and Eupelmus (Macroneura) vesicularis is recorded for the first time in Portugal. Additionally, a study of Malaise trap captures of species of Macroneura in an arid habitat in south-east Spain is presented and discussed. 358 individuals belonging to six species were collected and identified. Eupelmus (Macroneura) muellneri comprised 43.5% of the Macroneura and was the most abundant species followed by E. (M.) barai (25.4%).
