The giant anteater (Myrmecophaga tridactyla) is found from Belize and Guatemala to Paraguay and Argentina. Its conservation status is considered vulnerable by IUCN. Here we report the isolation and characterization of six microsatellite loci. Positive loci for (GT)(n) were isolated using a magnetic bead hybridization selection protocol. The number of alleles per locus as well as the heterozygos...

We studied a collection of lice from Argentina, Brazil, Paraguay and Chile containing all four known species and one new species (described herein) in the genus Tinamotaecola, parasites of birds of the families Cariamidae and Tinamidae. We also (1) describe previously unknown second and third nymphal instars of two Tinamotaecola species, (2) discuss hosts and geographical ranges for all Tinamot...
