The following Mexican ticks labeled as Amblyomma triste Koch, 1844, were found in the Colección Nacionalde Ácaros, Instituto de Biología, Universidad Nacional Autónoma de México: 4 males (M) and 4 females (F),ex cattle, Jun. 19, 1975, Las Pilas (28º49´N 102º00´W), Múzquiz, Coahuila; 1 M and 1 F, host, date and localityas above; 1 M, ex undetermined deer, Oct. 18, 1976, Yécora (28º22´N 108º56´W), Sonora. Both localities arein the Nearctic Zoogeographic Region. The ticks were confirmed as A. triste, thereby corroborating previousstatements concerning the presence of this tick in Mexico. The current known distribution of A. triste includesthe Neotropical and the Nearctic Zoogeographic Regions. Amblyomma triste is classified in the subgenusAnastosiella Santos Dias, 1963, whose members are difficult to differentiate in any stage. It is hoped thatconventional and molecular taxonomic studies of Anastosiella species will help to clarify their range andphylogenetic relationships.
