“…One of the original subspecies populations, confined to the Sahafary forest to the east of the Montagne d'Ambre, was raised to species level as L. andrafiamenensis. However, to judge from the discussion by Ravoarimanana et al, 39 who subsequently affirmed the hypothesis of cryptic speciation in northern Lepilemur, the name for this species, possibly now extinct, should probably be L. sahafarensis. The remaining northern populations, formerly grouped into three subspecies, were lumped into a monotypic L. septentrionalis.…”

“…All that can be said with certainty is that there is variation within Lepilemur and that much of this variation appears to be organized geographically. On the basis of the karyotypic and hybrid-recognition studies of Rumpler and his colleagues [38][39][40] it seems reasonable that most of the eight ''core'' taxa should provisionally be recognized at the species level. On the other hand, even quite large divergences in the cytochrome b gene seem to constitute rather weak evidence for speciation in the case of the three recently named species embedded within the ranges of L. ruficaudatus and L. dorsalis.…”

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.

“…On the basis of cytogenetic and molecular data, the subspecies of Lepilemur septentrionalis listed by Groves (2001) was elevated to species: L. ankaranensis (cf. Ravaoarimanana et al 1999Ravaoarimanana et al , 2004Rumpler et al 2002). Groves (2005) and Mittermeier et al (2006), therefore, listed 8 species of sportive lemurs, all of them cytogenetically distinct Rumpler and Albignac 1978;Rumpler et al 2001;Thalmann and Ganzhorn 2003;).…”

“…Forms occurring in both dry deciduous and humid forests that extend from Montagne d'Ambre southward to the Mahavavy River near Ambilobe and eastward at least as far as the Manambato River, and probably to the Fanambana River, north of Sambava, have been assigned to this taxon. The diploid chromosome number for the species ranges from 36 to 38 (Ravaoarimanana et al 2004;Rumpler et al 2001). Andriaholinirina et al (2006a) found that Lepilemur ankaranensis was more closely related to L. dorsalis than to L. septentrionalis.…”

A basic understanding of the taxonomy, diversity, and distributions of primates is essential for their conservation. This review of the status of the taxonomy of lemurs is based on a 5-d workshop entitled "Primate Taxonomy for the New Millennium," held at the Disney Institute, Orlando, Florida, in February 2000. The aim is not to present a taxonomic revision, but to review our current understanding of the diversity and current and past ranges of lemurs and indicate where there is controversy, discrepancy, or lack of knowledge. Our goal therefore is to provide a baseline for future taxonomic investigation, as well as a clearer focus for research Int J Primatol (2008) and conservation priorities. We here focus on the lemurs of Madagascar and recognize 5 families, 15 genera, and 99 species and subspecies. We list 39 species of lemurs described since 2000: 2 dwarf lemurs, Cheirogaleus; 11 mouse lemurs, Microcebus; a giant mouse lemur, Mirza; a bamboo lemur, Hapalemur; 17 sportive lemurs, Lepilemur; and 7 woolly lemurs, Avahi. Taxonomic revisions have resulted in the resurrection of a further 9 taxa. However, the figures do not represent the total diversity of Malagasy lemurs because more new species are being identified via new field studies and accompanying genetic research, and should be described in the near future.

“…The development of molecular genetic tools has enabled the detection of numerous cryptic species. Large genetic distances within traditionally recognised species, usually in combination with morphological, geographical, ecological or behavioural differences, have led to the discovery of cryptic species in a diverse range of organisms, from tropical butterflies (Hebert et al, 2004), to arctic flora (Grundt, 2006), fish (Feulner et al, 2006;Puckridge, 2013) and lemurs (Ravaoarimanana et al, 2004).…”

Revealing the hidden niches of cryptic bumblebees in Great Britain: Implications for conservation

a b s t r a c tBumblebees are ecologically and economically important, and some species have suffered dramatic population declines. The absence of morphological diagnostic characters for the identification of some species creates difficulties for basic ecological studies, and for conservation management. The widespread and commercially exploited bumblebee subgenus Bombus sensu stricto contains a cryptic species complex, known as the lucorum complex, which in Europe comprises B. lucorum, B. cryptarum and B. magnus. Little is known about these species and much of what has been reported is likely to have suffered from incorrect identification. Although the lucorum complex as a whole is common in Great Britain, we aimed to determine whether the populations of the individual species are vulnerable and require conservation action. Using genetic methods to distinguish them, we determined the geographic distribution and abundance of the lucorum complex species in Great Britain, and assessed the extent of niche differentiation between these species. We detected major differences in the geographic range, forage use and sensitivity to summer temperatures of the three species. Bombus lucorum was found to have the broadest distribution and diet, being present throughout mainland Great Britain, whereas B. cryptarum and B. magnus were absent from large areas of central and southern England. Bombus cryptarum and B. magnus were more likely to be found at sites with lower summer temperatures. Bombus magnus, the least abundant species, was found to exhibit an unusually tight biotope association with heathland habitat. This has conservation implications for B. magnus given the current threats to this habitat type.
