“…Northern specimens tended to be darker than southern specimens, and Thalmann et al (1993) reported a mixed pattern in the region of Mananara, and Groves (2001Groves ( , 2005 recognized 2 subspecies, Indri indri indri and I. i. variegatus, on the basis of this study. Indri indri indri from the northern part of the species' distribution, and typical of specimens reported from Anjanaharibe-Sud (Thalmann et al 1993) and Ambatovaky (Evans et al 1995), are almost entirely black.…”

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.

“…Among nonhuman primates, average vocalization streams are variable in length; however, longer vocalization streams are associated with species that rely upon elaborate vocal apparatus to increase vocalization length. The indri (Indri indri), a prosimian that uses air sacs to increase vocalization length, has a vocalization stream of 5 seconds (Thalmann, Geissmann, Simone, & Mutschler, 1993). The howler monkey (g. Alouatta), which possesses a large air sac beneath the hyoid bone that acts as a resonating chamber, as well as two lateral air sacs, has been documented vocalizing for more than 50 seconds in one breath (Sekulic & Chivers, 1986).…”

A handful of mammalian and avian species can imitate speech (i.e., sounds perceived by humans as those comprising the human communication system of language). Of those species, even fewer are capable of using speech to communicate. While there has been no empirical comparison of nonhuman speech users, parrots are presumed to be the most prolific. In this review, we identify several anatomical, neurological, and sociobiological features shared by parrots and humans that could account for why parrots might emerge as the most advanced nonhuman speech users. Apes and temperate oscine songbirds, due to their phylogenetic similarity to humans and parrots, respectively, are also included in the comparison. We argue that while all four taxa share hemispheric asymmetry of communication areas and basic sociality, humans and parrots share three additional features that are not completely present in apes and songbirds. Specifically, apes, unlike songbirds, parrots, and humans, are not considered vocal learners and do not have sufficient respiratory control to support a speech stream, while parrots, humans, and apes demonstrate complex affiliative social behavior. Along with the above anatomical, neurological, and sociobiological traits, parrots' affiliative long-term relationships, similar to that of humans, may help explain both groups' ability to produce and use a wide variety of sounds. Thus, this paper extends parrot-human cognitive comparisons by introducing another similarity-that of complex affiliative relationships-as a possible explanation for why parrots can produce and use speech to communicate.

“…Indri indri indri (Gmelin 1788) is distinguished by a predominantly black coat (Fig. 1a,b) often with white fur along the edges of the abdomen, a white pygal patch, and a white face ring (Thalmann et al 1993), while I. i. variegatus (Gray 1872) has a black and white coat along with a white head cap ( Fig. 1c-h).…”

“…The type specimens held in European museums are the black variant and are all from the northern extent of the species' range (Groves 2001). Thalmann et al (1993) described the distribution of Indri indri indri as located in the northern part of the species range (above S15°15′30′′) and I. i. variegatus in the southern part of the range, with an area of possible overlap in Mananara Nord (S16°23′) based on mixing of pelage patterns (Groves 2001). These distributions place I. i. indri in the northernmost extent of the range, between Anjanaharibe-Sud and Mananara Nord and I. i. variegatus from Mananara Nord south to Anosibe an'ala (Fig.…”

Genetic Analysis of the Indri Reveals No Evidence of Distinct Subspecies

Subspecies were traditionally defined by identifying gaps between phenotypes across the geographic range of a species, and may represent important units in the development of conservation strategies focused on preserving genetic diversity. Previous taxonomic research proposed that phenotypic variation between scattered Indri indri populations warranted the naming of two distinct subspecies, I. i. indri and I. i. variegatus. We tested these subspecific designations using mitochondrial sequence data generated from the control region or D-loop (569 bp) and a large section (2362 bp) of multiple genes and tRNAs known as Pastorini's fragment and nuclear microsatellite markers. This study used 114 samples of I. indri from 12 rainforest sites in eastern Madagascar, encompassing the entire range of the species. These genetic samples represent multiple populations from low-and high-elevation forests from both putative subspecies. Molecular analyses of the mitochondrial sequence data did not support the Conservation International, Arlington, Virginia 22202, USA two proposed subspecies. Furthermore, the microsatellite analyses showed no significant differences across the range beyond population level differentiation. This study demonstrates the utility of incorporating multiple lines of evidence in addition to phenotypic traits to define species or subspecies.Int J Primatol DOI 10.1007/s10764-016-9911-3 Electronic
