Obligate social parasites, or inquilines, exploit the colonies of free-living social species and evolved at least 80 times in ants alone. Most species of the highly specialized inquiline social parasites are rare, only known from one or very few, geographically isolated populations, and the sexual offspring of most inquiline species mates inside the maternal colony. Therefore, inquiline populat...

A quantitative catalogue of the parasitoids (almost exclusively Chalcidoidea) and inquiline Cynipidae recorded in the western Palaearctic from galls induced on Quercus by Cynipidae (Cynipini) is presented. Quantitative and national data are included with bibliographic references to almost all records published in 2011 and earlier. The catalogue is followed by two checklists, firstly one of the ...

I report the Þrst example of communal parasitism in galling aphids and quantify the effects of gall invasion by the inquiline aphid Tamalia inquilina Miller on its host, Tamalia coweni (Cockerell). On populations of the host plants Arctostaphylos spp., both T. coweni and T. inquilina exhibited facultatively communal behavior and co-occupied galls with no apparent agonistic interactions. Althoug...

Ant inquilines are obligate social parasites, usually lacking a sterile worker caste, which are dependent on their hosts for survival and reproduction. Social parasites are rare among the fungus-gardening ants (Myrmicinae: tribe Attini) and only four species are known until now, all being inquilines from the Higher Attini. We describe Mycocepurus castrator sp.n., the first inquiline social para...

Abstract Queens of the inquiline social parasite Acromyrmex insinuator are known to infiltrate mature colonies echinatior and exploit host’s perennial workforce by producing predominantly reproductive individuals while suppressing host reproduction. Here we report three cases an A. queen having joined incipient colony that contained only founding host-queen her small symbiotic fungus garden. We...

Two new species of gall midges (Diptera, Cecidomyiidae) Dasineura ovalifoliae and Clinodiplosis maricaensis are described based on material from the Barra de Maricá restinga, Maricá, Rio de Janeiro, Brazil. Both species are associated with Erythroxylum ovalifolium Peyr. (Erythroxylaceae). The former is the gall inducer and the latter an inquiline.
