Appearance

The species appears to be restricted to a small region of lowland evergreen rain forest, and is seriously threatened by forest loss.

Gerp's mouse lemur is significantly larger, weighing on average 68-gram (2.4 oz), compared to Goodman's mouse lemur, that weighs about 44 g (1.6 oz). Jolly's mouse lemur, that is its closest relative and a neighbor to the south, is comparably larger, but differs in tail length and genetics.

Range and habitat

Gerp's mouse lemur has only been identified in the Sahafina Forest in eastern Madagascar, about 58 km (36 mi) east of Mantadia National Park, 87 km (54 mi) south of the city of Toamasina, and 18 km (11 mi) from the Indian Ocean. The forest fragment is about 15.6 km2 (6.0 sq mi) and is surrounded by secondary forest growing in areas previously cut for rice cultivation (known locally as savoka). The Sahafina Forest ranges from 29 to 230 m (95 to 755 ft) above sea level, whereas nearby Mantadia National Park, home of its closest neighboring mouse lemur population (Goodman's mouse lemur), ranges from 900 to 1,200 m (3,000 to 3,900 ft) above sea level.

In crisis

Of the 7,600 km2 (2,900 sq mi) of its potential geographic range, only very small parts remain forested.

CITES lists this taxon on Appendix I. Confirm the current appendix on the CITES checklist.
