A subgeneric revision of Crematogaster and discussion of regional species-groups (Hymenoptera: Formicidae)
Crematogaster ants are diverse, widespread and abundant in tropical, subtropical and warm-temperate climates throughout the world. The species diversity of this genus has been notoriously difficult to manage based upon morphology alone, and former attempts have generated a vaguely defined subgeneric system. I propose an improvement of the previous subgeneric classification and recognize two sub...
متن کاملTaxonomy and species-groups of the subgenus Crematogaster ( Orthocrema) in the Malagasy region (Hymenoptera, Formicidae)
The species-level taxonomy of the subgenus Crematogaster (Orthocrema) in the Malagasy region is evaluated with both morphological data from worker and queen ants, and genetic data from three nuclear markers (long wavelength rhodopsin, arginine kinase and carbamoylphosphate synthase). These two types of data support the existence of six Orthocrema species: Crematogaster madecassa Emery, Crematog...
متن کاملCongruence of Microsatellite and Mitochondrial DNA Variation in Acrobat Ants (Crematogaster Subgenus Decacrema, Formicidae: Myrmicinae) Inhabiting Macaranga (Euphorbiaceae) Myrmecophytes
A previously reported mitochondrial DNA (mtDNA) phylogeny of Crematogaster (subgenus Decacrema) ants inhabiting Macaranga myrmecophytes indicated that the partners diversified synchronously and their specific association has been maintained for 20 million years. However, the mtDNA clades did not exactly match morphological species, probably owing to introgressive hybridization among younger spe...
متن کاملX-Ray microtomography for ant taxonomy: An exploration and case study with two new Terataner (Hymenoptera, Formicidae, Myrmicinae) species from Madagascar
We explore the potential of x-ray micro computed tomography (μCT) for the field of ant taxonomy by using it to enhance the descriptions of two remarkable new species of the ant genus Terataner: T. balrog sp. n. and T. nymeria sp. n.. We provide an illustrated worker-based species identification key for all species found on Madagascar, as well as detailed taxonomic descriptions, which include di...
متن کاملRedescription of Crematogaster cypria Santschi, 1930, new status, with description of two new related species from Greece and Turkey (Hymenoptera, Formicidae)
Crematogaster (Crematogaster) jehovaevar.cypria Santschi, 1930 is raised to species rank. Two new, related species are described from the north-eastern part of the Mediterranean Basin: Crematogaster (Crematogaster) erectepilosasp. n. (Dodecanese, Greece) and Crematogaster (Crematogaster) gullukdagensissp. n. (Antalya Prov., Turkey). These three species are well distinguished from other species ...
