Abstract
Larvae and pupae of the obligately myrmecophilous social parasites Microdon myrmicae (Diptera: Syrphidae) and Maculinea alcon (Lepidoptera: Lycaenidae) were found using exclusively Myrmica aloba (Hymenoptera: Formicidae) host ants in NE-Portugal. Ichneumon eumerus (Hymenoptera: Ichneumonidae) was also found developing in Ma. alcon pupae in nests of My. aloba at the same site. These are the first records of Mi. myrmicae and I. eumerus for Portugal, and from My. aloba nests. Earlier records that My. aloba is the only known host ant of Ma. alcon in Portugal are confirmed. Further studies on the biology of these isolated peripheral populations are necessary for their well-planned protection.
Notes
Based on formal taxonomic priority, it has been suggested that the generic name Phengaris Doherty, 1891 should replace Maculinea (see e.g. Fric et al. 2007; Pech et al. 2007). However, the case is still undecided by the International Commission on Zoological Nomenclature (ICZN 2012) and strong arguments for the precedence of Maculinea over Phengaris have been made (Balletto et al. 2010, and Comments on this Case). Hence we continue to use Maculinea as the accepted generic name of these butterflies.
As names of three genera (Maculinea, Microdon and Myrmica) mentioned frequently in this paper start with “M”, these are abbreviated with the first two characters for the easier readability.
