Distribution. Known only from the type locality.

Etymology. Named in honor of Timothy J. McCarthy   , collector of the only known specimen.

Diagnosis. Sorex mccarthyi   is a member of the S. salvini   species group and is distinguished from S. cristobalensis   , S. salvini   , and S. sclateri   of this group by being smaller in most body and skull measurements (compare Table 1 with measurements of the holotype given below). It is larger than S. stizodon   . Color is Russet Brown both dorsally and ventrally, tail slightly bicolor (Russet Brown above, slightly paler below).

Description. A small Sorex   , measurements of the holotype: TOT 111, Tail 51.5,HF 13, EL 7.5, 4.22 g, CBL 17.05, GLS 17.68, LR 7.55, PL 7.15, LUT 2.45, LMT 4.25, CB 8.12, WM2 4.60, LIB, 3.90, DB 5.15, LM 7.15, HC 3.21. U3 is subequal in size to U4. The lower first incisor has a single pigmented denticle. The anteriomedial tine on the first upper incisor is above the pigmented region. S. mccarthyi   has a short unicuspid toothrow relative to skull width and depth as compared to S. cristobalensis   and S. salvini   and S. sclateri   . It is larger in all measurements than S. stizodon   , but smaller than other species of the group.

Ecology. Sorex mccarthyi   is known only from the cloud forest at an upper elevation (2560 m) on Cerro Celaque, Honduras. Mammalian associates include: Cryptotis goodwini   , Heteromys desmarestianus   , Peromyscus oaxacensis   , P. beatae   , P. mexicanus   , Reithrodontomys mexicanus   , and Scotinomys teguina (unpublished manuscript).
