“…Avahi has been considered as the most primitive extant genus because of its small body size and nocturnal habits (Hill, 1953). The same position was posited for this taxon on the basis of karyological comparisons (Dutrillaux, 1988;Rumpler & Dutrillaux, 1990) and highly repeated DNA sequences (Razafindraibe, Montagnon & Rumpler, 1997). Stanger-Hall (1997) proposed a sister group relationship between Avahi and h d r i , on the basis of the absence of a P4 metaconid (bootstrap value of 63%), but the alternative grouping of either taxon with Pmpithecus required only one more step on the most parsimonious tree.…”

Numerous phylogenetic hypotheses have been advanced for the Malagasy lemuriform radiation, drawing on data from morphology, physiology, behaviour and molecular genetics. Almost all possible relationships have been proposed, ,md most nodes have been contested. We present a phylogenetic analysis, using several analytical methods, of a partial sequence from the 12s rRNA mitochondrial gene. This gene codes for the small ribosomal subunit, and functional constraints require that the secondary structure of the molecule is strongly conserved, which in idurn exerts constraints on the primary sequence structure. Although previous studies have suggested a very wide range of phylogenetic applicability for this molecule, our results indicate that it is most useful in strepsirrhine primates J'or estimating relationships among genera within families and among relatively recently diverged families (mean sequence divergence about 11Vo). Relationships among families separated by larger genetic distances (>12Vo divergence; e.g. Cheirogaleidae, Daubentoniidae, Megaladapidae) are difficult to resolve consistently. Our data show strong support for an Indridae-Lemuridae sister group and for monophyly of the Lemuridae with Varecia as the sister to all other lemurids. They also support, albeit less strongly, sister group relationships between Lemur and Hapalemur within the Lemuridae and between PmpLthecus and Avahi in the Indridae.

“…In 1988, Simons 64 named an additional karyotypically distinct species, P. tattersalli, which showed morphological attributes of both the others as well as external features of its own. Using highly repeated DNA, Razafindraibe et al 65 placed the new species as the outgroup to P. verreauxi þ P. diadema. In 1986 I reduced sifaka diversity by synonymizing the two subspecies P. d. edwardsi and P. d. holomelas, and by suggesting that the same might be true of P. v. coronatus and P. v. deckeni.…”

Madagascar's Lemurs: Cryptic diversity or taxonomic inflation?

We live in inflationary times. A quarter of a century ago, cigarettes were about $1 a pack in New York City, a bottle of Château Beaucastel set you back $15, and there were 36 different species of lemur alive in Madagascar1 (Table 1). Today the equivalent figures are $7.40, $95, and 83 lemur species2 (Table 1). The increase in dollar prices has a lot to do with the economics of growth, something that obviously cannot be sustained indefinitely on a finite planet. Is the recent inflation in lemur taxonomy any more secure? The question is all the more worth asking because this is no isolated phenomenon: Madagascar's primates have not been alone in multiplying. The same burgeoning of species names has occurred throughout the order Primates3, 4 and beyond,5 provoking both concern and energetic debate.6–9 Interestingly, this debate has largely unfolded among ecologists, conservationists, and other “consumers” of taxonomy; many “producers” seem to be content to generate new taxonomies with a remarkable lack of introspection, as if they were no more than passive consequences of more lofty concerns. And because the same causes underlie taxonomic inflation in Madagascar as elsewhere, this extraordinary island once again presents us with a microcosm of the larger world.
