Specimens of the collared anteater (Tamandua mexicana) from Tamaulipas, Mexico.

The collared anteater (Tamandua mexicana) is a Neotropical species whose geographical distribution extends from northern Peru into Mexico, where it reaches Colima on the Pacific Coast and Veracruz on the Gulf Coast (Hall, 1981; Ceballos and Oliva, 2005; Burton and Ceballos, 2006; Navarrete and Ortega, 2011). Previous records for Tamaulipas were anecdotal (Moreno-Valdez and Vasquez-Farias, 2005) and, although the collared anteater has been observed in Reserva de Biosfera de El Cielo, there was no specimen from the state. Collared anteaters liveintropicalrainforests, deciduous forests, cloud forests, and mangroves (Navarrete and Ortega, 2011). Although they usually occur in dense forests, the species can be in anthropogenically transformed areas such as agricultural zones and secondary vegetation. They have been recorded from sea level to 2,000 m, but more commonly <1,000 m (Ceballos and Oliva, 2005; Navarrete and Ortega, 2011).

In July 1984, at Lauro Aguirre, municipality of Aldama, southeastern Tamaulipas (23[degrees]0'45''N; -98[degrees]01'47W; 360 m elevation), a female T. mexicana was killed by a hunter. The skin was preserved and donated to the Coleccion Zoologica of the Museo de Historia Natural de Tamaulipas (TAMUX001). The area where it was collected was a tropical deciduous forest dominated by custard apple trees Annona globiflora, gumbo-limbo trees Bursera simaruba, and guazima trees Guazuma ulmifolia. In July 1999, at Tantoyuquita, municipality of El Mante, Tamaulipas (22[degrees]32'41 "N; -98[degrees]33'10"W; 10 m elevation), a local resident killed a juvenile T. mexicana and the skin was preserved. This specimen also was donated to the Coleccion Zoologica of the Museo de Historia Natural de Tamaulipas (TAMUX002). On 12 September 2006, a live adult male T. mexicana was captured by villagers at Rancho Nuevo, municipality of Aldama (23[degrees]18'10"N; --97[degrees]45'40"W; 40 m elevation); it was later seized by federal environmental authorities. Presently, this individual is at Tamatan Zoo (Zoologico de Tamatan; identification 13092006) in Ciudad Victoria, Tamaulipas. Habitat of the area where it was captured was coastal dunes and mangroves, dominated by black mangroves Avicennia germinans. The area was a successional stage of tropical deciduous forest where dominant species were ebony trees Pithecellobium ebano, cherimoya trees A. cherimola, B. simaruba, and G. ulmifolia adjacent to cornfields (Zea mays) and pastures. On 20 January 2011, at Nueva Apolonia, municipality of El Mante (22[degrees]29'40N; -98[degrees]37'57''W; 93 m elevation), an adult female T. mexicana was captured by local residents and released alive a week later. Photographs were taken. Habitat was a riparian area surrounded by agriculture (mainly cornfields).

Tamandua mexicana has a wide distribution in Mexico (Hall, 1981; Ceballos and Oliva, 2005). However, knowledge about it in northeastern Mexico was limited to anecdotal records. Specimens provide high credibility compared to reports based only on observations (McKelvey et al., 2008). We provide the first confirmed records of T. mexicana for Tamaulipas. Previously, the northernmost locality of a specimen in eastern Mexico was the municipality of Tamazunchale, San Luis Potosi (Hall, 1981). our records extend the distribution of T. mexicana 243 km to the northeast. It is difficult to ascertain the northern limits of its geographic range because this species likely occurs in low densities. Moreover, accelerated destruction of habitats likely is affecting size of populations, as well as continuity among populations.
