Goodwin’s Broad-clawed Shrew

Cryptotis goodwini

French: Musaraigne de Goodwin / German: Goodwin-Kleinohrspitzmaus / Spanish: Musarana de unas anchas de Goodwin

Other common names: Goodwin's Small-eared Shrew

Taxonomy. Cryptotis goodwini H. H. T. Jackson, 1933, “Calel, altitude 10200 feet [= 3109 m], Guatemala.”

Cryptotis goodwini is in the C. goodwini group, which includes C. goodwini, C. mam, C. mag- nimana, C. lacertosus, C. mccarthy, C. griseoventris, C. celaque, C. cavatorculus, and C. gracilis . The C. goodwini group is sister to the C. goldmani group, and the C. parvus group 1s sister to this clade. A specimen identified as C. goodwini from Chiapas, Mexico, clus-

tered with specimens of C. mam in a phylogenetic study by A. B. Baird and colleagues in 2018, although additional sampling is needed to determine phylogenetic placement of this species. Cryptotis magnimana was previously included as a subspecies of C. goodwini, and populations now attributed to C. cavatorculus, C. mccarthyi, C. celaque, C. lacertosus and C. oreoryctes were previously included in C. goodwini . As currently recognized, C. goodwini probably still represents a complex of species; additional research is needed. Monotypic.

Distribution. Currently known from highlands of Chiapas (SE Mexico), Guatemala, and NW El Salvador; distributional limits are somewhat uncertain and the map provided is tentative.

Descriptive notes. Head—body 75-94 mm, tail 25-34 mm, hindfoot 14-17 mm; weight 16-19 g. Goodwin’s Broad-clawed Shrew is mediumto very large-sized, with broad forefeet and claws. Dorsum is dark brown, and venter is lighter olive brown, mixed with gray. Feet are relatively long and broad, with long wide claws. Tail is very short (¢.35% of head-body length), dark brown, and covered with short hair. Eyes are diminutive, and ears are small and barely visible under fur. Coccidian parasites Eimeria hondurensis and Eimeria whitakeri and the tick Ixodes guatemalensis have been recorded from Goodwin's Broad-clawed Shrew. Fourth unicuspid is aligned with unicuspid row and is usually partially obscured or not visible in lateral view of skull. Humerus is robust butless so than that of the Highland Broad-clawed Shrew ( C. oreoryctes). Teeth are reddish, and there are four unicuspids.

Habitat. High montane forests and cloud forests dominated by pine and oak with many epiphytes, occasionally with cypress ( Cupressus, Cupressaceae), fir ( Abies, Pinaceae), or alder ( Alnus, Betulaceae), generally at elevations of 1200-3350 m.

Food and Feeding. There is no specific information available for this species, but Goodwin’s Broad-clawed Shrew probably eats small invertebrates.

Breeding. Lactating Goodwin’s Broad-clawed Shrew have been captured in July and December, and pregnant females have been captured in April and July. One female had two embryos and the other had three embryos in July, and another female had two embryos in April.

Activity patterns. Goodwin's Broad-clawed Shrew is semi-fossorial and possibly primarily nocturnal.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Least Concern on The [UCN Red List. Goodwin's Broad-clawed Shrew is relatively wide-ranging and common, being found in various protected areas (e.g. Montecristo National Park in El Salvador, El Triunfo Biosphere Reserve in Mexico, and Sierra de las Minas Biosphere Reserve in Guatemala). There are limited data pertaining to its ecology. Deforestation seems to be the largest threat, particularly because rates of habitat loss in highlands of Chiapas, Mexico, have reached nearly 40% in recent years. Additional research on ecology and threats of Goodwin's Broad-clawed Shrew are needed.
