This shrew is known from Honduras. The Mammal Diversity Database currently uses Cryptotis magnimanus; a 1999 account treated it as C. goodwini magnimana.
The only known specimen had brown fur, a slightly paler underside, and silvery-grey hair bases with brown tips.
A female found in Honduras in November carried four embryos: three in the right uterine horn and one in the left. Their crown-to-rump length was eight millimetres.
Collected on 21 November 1991 in Montecillos reserve, this female was described in 1999. The locality was 2.5 kilometres north and 1.6 kilometres east of Cerro San Juanillo, at 1,730 metres elevation. Researchers examined the skull and forelimb bone removed from her fluid-preserved body. With no external measurements recorded by the collectors, they measured the preserved specimen before removing its skull, recording a head-and-body length of eight centimetres.
An extinction-risk assessment has not been added yet.
The discovery locality lies in Montecillos reserve. On 21 December 2023, ASIDE reported reforestation and agroforestry restoration on productive land bordering the reserve, together with maintenance around naturally regenerating seedlings.
