This is probably the smallest living galago species with relatively long “bottle-brush” tail and long ears (Groves 2001). Its back is mid-brown that becomes yellow pale towards the belly and it has a whitish face strip but not very dark eye-rings (Groves 2001). Advertising call is categorized as a rolling call (Grubb et al. 2003).

Body measurements:

  • Head and body:  130.8 (123-137) mm, n = 7)
  • Tail :  168.5 (174-177) mm, n = 7
  • Weight:  69.2 (60-73) g, n = 7

Common name: Rondo Dwarf Galago

Type locality: Rondo Forest Reserve, Rondo Plateau, Lindi District, Lindi Region, Tanzania, (10°7'S 39°23'E)

Kingdon (1997) attributed the name to Honess (1996) but failed to recognize that it was from his unpublished thesis. The name was later officially mentioned in a paper by Honess and Bearder dated to 1996 but published after Kingdon’s book (1997).

There are no subspecies described but there are some differences in call structure between the southern population (e.g. Rondo FR) and northern populations (e.g. Pugu FR) (Perkin pers. obs.).

Extract from Perkin et al. (2008):

"This species is known from seven isolated forest patches: Zareninge, Pande Game Reserve, Pugu/Kazimzumbwe, Rondo, Latipo and Ziwani. It occurs at elevations of 100-900 m. The known distribution encompasses 92 km² of coastal forest. The occurrence of the species between these forest patches is unknown."

Map: Pink areas illustrate the current estimated distribution of G. rondoensis. Our suggested survey site is near Dar es Salaam (square 1) at Pugu Forest Reserve.

IUCN Classification: Critically Endangered   B1ab(ii,iii)   ver 3.1

Listed on Appendix II of CITES

Main threat is habitat clearance. Known distribution 92.6 km2 of coastal forest including Pande Game Reserve 2.4 km2, Rondo 25 km2, Ziwani 7.7 km2, Pugu/Kazimzumbwi 33.5 km2, Litipo 4 km2 and Zareninge Forest Reserves 20 km2 (Burgess & Clarke 2000, Perkin 2004). All sites require improved management. Further surveys in potential habitat areas and research on intra-population variation necessary.
