A new workerless inquiline in the Lower Attini (Hymenoptera: Formicidae), with a discussion of social parasitism in fungus-growing ants
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...
متن کاملA taxonomic revision of the seed-harvester ant genus Pogonomyrmex (Hymenoptera: Formicidae) on Hispaniola.
We revise species of seed-harvester ants in the genus Pogonomyrmex (subfamily Myrmicinae) that occur on the Caribbean island of Hispaniola. Three species are recognized: P. aterrimus Wheeler (new status), P. saucius Wheeler and Mann, and P. schmitti Forel. Pogonomyrmex schmitti sublaevigatus Wheeler (= schmitti) and P. schmitti darlingtoni Wheeler (= aterrimus) are synonomized. We also describe...
متن کاملColony founding by pleometrosis in the semiclaustral seed-harvester ant Pogonomyrmex californicus (Hymenoptera: Formicidae)
Pleometrosis, or colony founding via multiple queens, occurs in a localized population of the seedharvester ant Pogonomyrmex californicus. In an apparently unusual secondary modification, queens of P. californicus are also obligate foragers; that is, queens must forage to garner the resources necessary to rear their first brood. Laboratory experiments measured the costs and benefits of pleometr...
متن کاملThe Relation of Recruitment Rate to Activity Rhythms in the Harvester Ant, Pogonomyrmex barbatus (F. Smith) (Hymenoptera: Formicidae)
The response of a colony of Pogonomyrmex barbatus to bait depends on the activities of the colony at the time bait is offered. Colony activities are temporally patterned within the morning activity period. Both the peak of nest-maintenance work and the onset of the peak of patrolling occur earlier than the peak of foraging. The rate of recruitment to bait is positively correlated with the numbe...
متن کاملMolecular evidence for the origin of workerless social parasites in the ant genus Pogonomyrmex.
Speciation of two social parasites from their respective hosts is tested using a molecular phylogeny. Alignment of 711 DNA base pairs of mitochondrial cytochrome b gene was used to assess phylogenetic relationships of inquiline species to their hosts and to other members of the genus. We show that the inquiline social parasites of the North American seed harvester ants are monophyletic, descend...
