Taxonomy. Cryptotis gracilis G. S. Miller, 1911 View in CoL ,
“ head of Lani River , near base of Pico Blanco, Talamanca, Costa Rica. Alti- tude about 6,000 feet [= 1829 m].”
Cryptotis gracilis is in the C. goodwini group. It was regarded as a relict species by J. R. Choate in 1970 and was found to be basal to all other species in the C. goodwini group by A. B. Baird and colleagues in 2018. P. A. Moreno in 2017 found that a specimen of C. gracilis was more nested in
the C. thomasi group,sister to a clade including C. equatoris and C. osgoodi, but additional sampling is needed. Monotypic.
Distribution. Highlands from NC Costa Rica S to W Panama. View Figure
Descriptive notes. Head-body 60-79 mm,tail 30-41 mm, hindfoot 13-15 mm; weight 5-10 g. The Talamancan Broad-clawed Shrew is small to medium-sized.
