Comparison between the current consensus taxonomy and the taxonomy as indicated by mtDNA sequence data of lemur taxa on opposite sides of three rivers

River	Current taxonomy	Relative genetic distances, %	mtDNA taxonomy
Betsiboka (NW and W1)	E. mongoz	0.63–0.72	1 species
	E. f. fulvus–E. f. rufus	2.33–2.41	2 subspecies
	P. v. coquereli–P. v. coronatus	5.25–5.50	2 species
	L. edwardsi	11.06–11.23	2 species
Mahavavy (in W1)	E. mongoz	0.34–0.42	1 species
	E. f. rufus	0.21–0.42	1 subspecies
	P. v. coronatus–P. v. deckeni	0.25–0.85	1 subspecies
Tsiribihina (W1 and W2)	E. f. rufus	2.28–2.54	2 subspecies
	P. v. deckeni–P. v. verreauxi	0.85–1.02	1 subspecies
Betsiboka and Mahavavy*	H. g. occidentalis	1.99–2.03	2 subspecies
Mahavavy and Tsiribihina*	L. edwardsi–L. ruficaudatus	6.02–6.19	2 species
All three rivers*	M. murinus	2.54–2.62	2 subspecies

^*Because of incomplete taxon sampling, the genetic divergence spans more than one river.
