State Record for Stenamma foveolocephalum (Hymenoptera: Formicidae) in Missouri

We report the first known collection of Stenamma foveolocephalum (Hymenoptera: Formicidae) from Missouri. Two specimens were collected in pitfall traps during a field study at Sand Prairie Conservation Area, Scott County, Missouri

Check list of ground-dwelling ant diversity (Hymenoptera: Formicidae) of the Iguazú National Park with a comparison at regional scale

We describe the ant fauna of Iguazú National Park (INP), a region of high biodiversity andendemism in northeastern Argentina that includes the southernmost protected area ofthe Atlantic Forest (AF). Ants were sampled over seven periods from 1998 to 2011 usinga variety of techniques. We also surveyed museum collections and the scientific literatureto obtain additional records of ants from INP. In addition to providing a species list, wecompare ant composition of INP to other sites in the Upper Paraná, Serra do Mar CoastalForest and Araucaria ecoregion of AF. A total of 172 ant species belonging to 56 genera arereported; 56 species are new records for Misiones Province and 39 species are reportedfrom Argentina for the first time. Alto Paraná and Canindeyú departments in Paraguaypresent the most similar ant fauna to INP. Serra da Bodoquena in Brazil and Pilcomayoin Argentina showed higher similarity with the Upper Paraná AF ecoregion, despite thatSerra da Bodoquena is composed of a mix of ecoregions. Ant diversity was lower in UpperParaná than in Serra do Mar Coastal Forest ecoregion. This difference may result fromhigher primary productivity and a greater altitudinal variation in the coastal region.Fil: Hanisch, Priscila Elena.

Tetramorium Parvioculum Sp. N. (FORMICIDAE: MYRMICINAE), A new species of the T. Simillimum group from Gibraltar

We describe a new species of Tetramorium, which has so far only been found in Gibraltar. Tetramorium parvioculum sp. n. belongs to the simillimum-group, which is of Afrotropical origin. It is likely that this species is a non native and was imported with plant material originating from tropical Africa. The ecology of this new species is discussed

Checklist of the Ants of Michigan (Hymenoptera: Formicidae)

A total of 113 species of ants is recorded by county from the state of Michigan. The list is based upon literature records and specimens in the authors\u27 collections and those of the University of Michigan Museum of Zoology and the Michigan State University Department of Entomology. The list includes 3 species in Ponerinae, 44 in Myrnucinae, 6 in Dolichoderinae, and 60 in Formicinae. Ten species represent new state records. Five distribution pat- terns are evident: statewide (39 species), southern counties only (5), southern 3/4th of Lower Peninsula (10), Lower Peninsula (17), and Upper Peninsula (2). Forty species have been collected too infrequently to determine the distribution within the state

Expansion of the geographic range of Cyatta abscondita Sosa-Calvo et al., 2013 (Hymenoptera: Formicidae)

The presence of the recently described fungus-farming ant genus and species Cyatta abscondita is reported in the northwestern region of Misiones Province in Argentina. A single worker of C. abscondita was collected in a pitfall trap in a mature plantation of Pinus taeda in the Atlantic Forest biome. This finding expands the distribution of the genus and species, extending it farther south in the Neotropics.Fil: Ramos, Carolina Samanta. Consejo Nacional de Investigaciones Científicas y Técnicas.
