Based on study of ticks deposited in the Colección Nacional de Ácaros, Instituto de Biología, Universidad Nacional Autónoma de México, we report the fi rst records in Mexico for two species of Amblyomma: Amblyomma calcaratum ex Tamandua mexicana, and Amblyomma pacae ex Tapirus bairdii. These new records increase the number of species recorded for the genus Amblyomma in Mexico to 26. Key words: Amblyomma calcaratum, Amblyomma pacae, Ixodidae, Mexico. Resumen. Basado en la revisión de garrapatas depositadas en la Colección Nacional de Ácaros, Instituto de Biología, Universidad Nacional Autónoma de México, establecemos los primeros registros en México para 2 especies del género Amblyomma: Amblyomma calcaratum ex Tamandua mexicana y Amblyomma pacae ex Tapirus bairdii. Estos nuevos registros incrementan a 26 el número de especies del género Amblyomma distribuidas en México. Palabras clave: Amblyomma calcaratum, Amblyomma pacae, Ixodidae, México. The genus Amblyomma (Koch, 1844) is one of the largest Paulo, Brazil). within Ixodida, and includes 130 species (Horak et al., The specimens identifi ed originally as A. coelebs were re- 2002). Twenty four species have been recorded in Mexico identifi ed as A. calcaratum, while identifi cation of A. pacae parasitizing amphibians (2 species), reptiles (6), birds (2) was confi rmed. Additionally, we present morphological and mammals (14), distributed mainly in the Neotropical diagnoses of both species, discussing briefl y the main region (18 tick species) (Table 1). characteristics used in their determination.
