 Primate Conservation. 31;

 A new species in the genus Cheirogaleus is described from Ranomafana and Andringitra national parks, Madagascar. Ranomafana National Park is a rainforest situated in a montane region, and Andringitra National Park is comprised of grassland, lowland and highland forests displaying great altitudinal variation. Both parks are known to harbor wide species diversity in flora and fauna. Genetic and morphometric analyses of the samples collected at these localities confirmed that this Cheirogaleus lineage represents a new species in the C. crossleyi group, and here we elevate it to species status as Cheirogaleus grovesi, for the British-Australian biological anthropologist, evolutionary biologist and taxonomist Colin Groves.

Key Words: Cheirogaleus, dwarf lemur, cryptic species, Madagascar

 Cheirogaleus grovesi
 Formerly Cheirogaleus sp. nov. 2, also CCS3/Crossleyi D (Lei et al. 2014), 
also Cheirogaleus sp. Ranomafana Andrambovato (Thiele et al. 2013).

Description. The dorsum, limbs, and head are rufous-brown. The areas around the orbits are brownish-black, with a white patch proximal to the fleshy part of the nose in the inter-ocular space. The pelage on the ventral surface of the mandible is white, which continues onto the rufous-grey pelage of the ventrum.


Distribution. Cheirogaleus grovesi is known from the national parks of Ranomafana and Andringitra, as well as surrounding areas, and likely occupies a fragmented range between the two parks across the Haute Matsiatra region of Madagascar. Observed at 754–999 m above sea level (Fig. 3).

Etymology. This species is named for the late British-Australian biological anthropologist, Professor Colin Groves (1942- 2017), in recognition of his more than forty years of work in the fields of primatology, evolutionary biology, morphological analysis, mammalian taxonomy and associated disciplines. Professor Groves embodied the true spirit of collaboration. His fastidious research on historical collections incorporated the work of those that preceded him, which he combined with the efforts of his contemporaries, creating compositions that span hundreds of years of scientific exploration. At the time of his passing, Professor Groves was widely regarded as the greatest living primate taxonomist.

Vernacular Names. Groves’, Andringitra, or Haute Matsiatra dwarf lemur.
