“…Monophyly of Pseudocheiridae as represented by Petauroides and Pseudocheirus was strongly supported by ND2 in accordance with microcomplement fixation (Baverstock et al, 1990b) and DNA-DNA hybridization (Westerman et al, 1990) studies. A close association between Dactylopsila and Dactylonax was also confirmed, although the levels of divergence between them indicates that they are quite distinct genera (see also Edwards and Westerman, 1992).…”

“…The most comprehensive phylogenetic studies of Pseudocheiridae are based on microcomplement fixation studies with albumin (Baverstock et al 1990b ), single-copy DNA-DNA hybridization data (Springer et al 1992 ), craniodental characters (Springer 1993 ), and concatenated nuclear gene sequences (Meredith et al 2009a ). Baverstock et al ( 1990b ) treated all pseudocheirid species except for Petauroides volans as members of the genus Pseudocheirus , but their taxonomic sampling included representatives of all pseudocheirid genera as currently recognized by Groves ( 2005 ). Baverstock et al’s ( 1990b ) microcomplement fixation analyses provided support for three primary lineages: Pseudochirulus + Pseudocheirus , Hemibelideus + Petauroides , and Pseudochirops + Petropseudes (Baverstock et al 1990b ).…”

A Phylogeny and Timescale for the Evolution of Pseudocheiridae (Marsupialia: Diprotodontia) in Australia and New Guinea

et al. 2010

View full text Add to dashboard Cite

Pseudocheiridae (Marsupialia: Diprotodontia) is a family of endemic Australasian arboreal folivores, more commonly known as ringtail possums. Seventeen extant species are grouped into six genera (Pseudocheirus, Pseudochirulus, Hemibelideus, Petauroides, Pseudochirops, Petropseudes). Pseudochirops and Pseudochirulus are the only genera with representatives on New Guinea and surrounding western islands. Here, we examine phylogenetic relationships among 13 of the 17 extant pseudocheirid species based on protein-coding portions of the ApoB, BRCA1, ENAM, IRBP, Rag1, and vWF genes. Maximum parsimony, maximum likelihood, and Bayesian methods were used to estimate phylogenetic relationships. Two different relaxed molecular clock methods were used to estimate divergence times. Bayesian and maximum parsimony methods were used to reconstruct ancestral character states for geographic provenance and maximum elevation occupied. We find robust support for the monophyly of Pseudocheirinae (Pseudochirulus + Pseudocheirus), Hemibelidinae (Hemibelideus + Petauroides), and Pseudochiropsinae (Pseudochirops + Petropseudes), respectively, and for an association of Pseudocheirinae and Hemibelidinae to the exclusion of Pseudochiropsinae. Within Pseudochiropsinae, Petropseudes grouped more closely with the New Guinean Pseudochirops spp. than with the Australian Pseudochirops archeri, rendering Pseudochirops paraphyletic. New Guinean species belonging to Pseudochirops are monophyletic, as are New Guinean species belonging to Pseudochirulus. Molecular dates and ancestral reconstructions of geographic provenance combine to suggest that the ancestors of extant New Guinean Pseudochirops spp. and Pseudochirulus spp. dispersed from Australia to New Guinea ∼12.1–6.5 Ma (Pseudochirops) and ∼6.0–2.4 Ma (Pseudochirulus). Ancestral state reconstructions support the hypothesis that occupation of high elevations (>3000 m) is a derived feature that evolved on the terminal branch leading to Pseudochirops cupreus, and either evolved in the ancestor of Pseudochirulus forbesi, Pseudochirulus mayeri, and Pseudochirulus caroli, with subsequent loss in P. caroli, or evolved independently in P. mayeri and P. forbesi. Divergence times within the New Guinean Pseudochirops clade are generally coincident with the uplift of the central cordillera and other highlands. Diversification within New Guinean Pseudochirulus occurred in the Plio-Pleistocene after the establishment of the Central Range and other highlands.Electronic supplementary materialThe online version of this article (doi:10.1007/s10914-010-9129-7) contains supplementary material, which is available to authorized users.

“…However, prior to the elevation of pseudocheirids to family status (Aplin and Archer 1987), most species were uniformly placed in the umbrella genus Pseudocheirus with the exception of Petauroides volans Kerr, 1792 due to its gliding locomotion. Molecular phylogenetic research on pseudocheirids in the 1980s confirmed the morphology‐based subgeneric and monophyletic groupings of Pseudocheirus and revealed the diverse nature of the family (Baverstock 1984; Baverstock et al . 1987, 1990; Springer et al .…”

: Four genera of extinct ringtail possums have been reported from Australian Oligocene to Miocene sediments since 1987. The genus Marlu was described from two species, M. kutjamarpensis and M. praecursor (Woodburne, Tedford and Archer), from the Miocene Kutjamarpu Local Fauna (Leaf Locality) and late Oligocene Wadikali Local Fauna respectively, of northern South Australia. New fossil material referable to this genus has been collected from the Leaf Locality and the Oligocene to Miocene Riversleigh World Heritage Area in northwest Queensland. Three new species, Marlu karya sp. nov. from middle Miocene Riversleigh local faunas and Marlu syke sp. nov. and Marlu ampelos sp. nov. from the Leaf Locality as well as early to middle Miocene Riversleigh local faunas are described. A revision and rediagnosis of the genus and published species are made following the re‐examination of referred material in conjunction with the new material. Marlu is characterized by simple dentition and synapomorphies with extant pseudocheirids such as a conjoined postmetacristid and preentocristid on m1 and the loss of the entostylid ridge. New material from middle Miocene Riversleigh deposits has been referred to M. kutjamarpensis, extending the known distribution and age of that species. Re‐examination of M. praecursor has revealed the presence of a small m1 entostylid ridge, contributing further to differences between M. praecursor and all other Marlu species and raising the possibility that Marlu is paraphyletic. The new material does not contradict a sister group relationship between ‘Marlu’ (excluding M. praecursor) and the Pliocene–Pleistocene genus Pseudokoala. Homology of the pseudocheirid m1 protostylid identified in species of Paljara, Pildra and Marlu with that observed in extant species is reconsidered. The ‘protostylid’ of the extinct genera is herein described as the buccal stylid.
