description: 108. Oaxacan Broad-clawed Shrew <i>Cryptotis peregrinus</i> <b>French:</b> Musaraigne pelerine / <b>German:</b> Oaxaca-Kleinohrspitzmaus / <b>Spanish:</b> Musarana de unas anchas de Oaxaca <b>Other common names:</b> Mexican Mountain Shrew <b>Taxonomy.</b> Blarina mexicana peregrina Merriam, 1895, “ mountains 15 miles [= 24 km] west ofcity of Oaxaca, Mexico (al- titude, 9,500 feet [= 2896 m]).” Restricted by L. N. Carraway in 2007 to “latitude 16-89°N, longitude 96-88°W.” Cryptotis peregrinus was considered a subspecies of C. mexicanus until N. Woodman and R. M. Timm in 1999 recognized it as a distinct species. L. Guevara and F. A. Cervantes in 2014 and A. B. Baird and col- leagues in 2018 found that C. peregrinus was in the C. goldmani group, with C. goldmani and C. alticola, and sister to C. goldmani. Monotypic. <b>Distribution.</b> Sierra de Cuatro Venados and Sierra Yucuyagua, W &amp; C Oaxaca (SC Mexico). <b>Descriptive notes.</b> Head-body 66-78 mm, tail 24-33 mm, hindfoot 12 mm (average); weight 3-5 g. The Oaxacan Broad-clawed Shrew is medium-sized. Dorsum is dark brown, and venteris lighter brown, being externally very similar to Goldman’s Broadclawed Shrew (C. goldmani). Feet are relatively long and broad, with long wide claws. Tail is short (¢.33% of head-body length), covered with short hair, and slightly bicolored, being darker above than below. Eyes are diminutive, and ears are small and barely visible under fur. Zygomatic processes extend posteriorly and ventro-laterally to below occlusal surface of teeth; zygomatic plate is narrower than in other species in the C. goldmani group; fourth unicuspid is partial obscured or notvisible when viewing skull laterally; and I, has two denticles and deep interdenticular space. Teeth are reddish, and there are four unicuspids. <b>Habitat.</b> Wet meadow in cloud forest at an elevation of 2860 m (type locality). <b>Food and Feeding.</b> There is no specific information available for this species, but the Oaxacan Broad-clawed Shrew probably eats invertebrates. <b>Breeding.</b> No information. <b>Activity patterns.</b> No information. <b>Movements, Home range and Social organization.</b> No information. <b>Status and Conservation.</b> Classified as Data Deficient on The IUCN Red List (as C. peregnna). The Oaxacan Broad-clawed Shrew has a restricted distribution and is probably most threatened by deforestation. It is known only from relatively few older specimens, and recent surveys have failed to collect new specimens. <b>Bibliography.</b> Alvarez-Castarieda, Cuarén &amp; de Grammont(2016), Baird etal.
