Lemur Lookalikes Are Two New Species, DNA Says

Mar. 26, 2013 — Scientists have identified two new species of mouse lemur, the saucer-eyed, teacup-sized primates native to the African island of Madagascar.

The new study brings the number of recognized mouse lemur species to 20, making them the most diverse group of lemurs known. But because these shy, nocturnal primates look so much alike, it's only possible to tell them apart with genetic sequencing.

The new mouse lemurs weigh 2.5 to 3 ounces (about 65 to 85 grams) and have grey-brown fur. "You can't really tell them apart just looking at them through binoculars in the rainforest," said senior author Peter Kappeler of the German Primate Center in Goettingen, who earned his PhD at Duke in 1992.

The researchers named one of the new species the Anosy mouse lemur, or Microcebus tanosi. Anosy mouse lemurs are close neighbors with grey mouse lemurs and grey-brown mouse lemurs, but the genetic data indicate they don't interbreed.

The researchers named the other new species the Marohita mouse lemur, or Microcebus marohita, after the forest where it was found. In Malagasy, the word "marohita" means "many views."
