Item Phylogenetic relationships of the enigmatic harpy fruit bat, Harpyionycteris (Mammalia, Chiroptera, Pteropodidae) ; American Museum novitates, no. 3533(New York, NY : American Museum of Natural History, 2006) Giannini, Norberto P.; Almeida, Francisca Cunha.; Simmons, Nancy B.; DeSalle, Rob.Harpy fruit bats, two closely related species in the genus Harpyionycteris (Chiroptera: Pteropodidae), exhibit a suite of unique craniodental traits. For this reason, the affinities of these bats have remained unclear, and most systematists have placed them in a group of their own (Harpyionycterinae Miller, 1907). The multicuspidate pattern of the cheek teeth in Harpyionycteris has generated speculation that it may represent an ancestral tribosphenic pattern lost in other pteropodids. In this contribution we propose a phylogenetic placement of Harpyionycteris based on parsimony analysis of complete sequences from two coding genes, the nuclear vWF (exon 28) and the mitochondrial cytochrome b (cyt-b). Both datasets, independently and in combination, strongly support a close relationship between Harpyionycteris and Dobsonia, as originally proposed by Andersen (1912, Catalogue of Chiroptera, British Museum Trustees). In turn, this group nests deeply inside Pteropodidae but it is not closely related to any particular suprageneric clade. Based on other data, we postulate that Aproteles also belongs in this group and therefore propose the expansion of Harpyionycterinae to include Harpyionycteris, Aproteles, and Dobsonia. Regarding the dentition, our results strongly reject the tribosphenic hypothesis advanced by some authors. The multicuspidate cheek tooth pattern seen in Harpyionycteris appears uniquely derived and related to specialized feeding habits and it thus has no direct bearing on the evolution of the typical pteropodid dentition from the tribosphenic pattern of microchiropterans and other mammals.Item A species-level phylogeny of Old World fruit bats with a new higher-level classification of the Family Pteropodidae. (American Museum novitates, no. 3950)(American Museum of Natural History., 2020-04-13) Almeida, Francisca Cunha.; Simmons, Nancy B.; Giannini, Norberto P.;Old World fruit bats (Chiroptera: Yinpterochiroptera: Pteropodidae) are a diverse radiation endemic to the tropics of Africa, Asia, Australia, and nearby island archipelagos. Recent molecular analyses have provided considerable resolution of phylogenetic relationships within this group, but many points of uncertainty have remained including the position of several enigmatic taxa (e.g., Notopteris, Eidolon), relationships among species in more diverse subfamilies and genera (e.g., Pteropodinae, Pteropus, Epomophorus), and topology of the backbone of the tree. Here we provide a new, synthetic analysis including representatives of all 45 currently recognized genera and enhanced sampling in several speciose genera. Our matrix included four nuclear genes regions (vWF, RAG1, RAG2, and BRCA1) and four mitochondrial gene loci (Cytb, tRNA valine, 12S rRNA, and 16S rRNA) for a total of >8000 bp including new sequence data for 13 species. Maximum likelihood and Bayesian analyses resulted in trees supporting recognition of six main suprageneric clades similar in content to those identified in our previous studies. We did not recover strong support for relationships among the main clades along the backbone of the tree, but identified many well-supported clades within all of the major groups. Based on these results, we propose a new classification for Pteropodidae comprising eight subfamilies and 14 tribes, and including several new and/or replacement higher-level taxonomic names for which we provide morphological diagnoses.Item Supplemental Material for 'A species-level phylogeny of Old World fruit bats with a new higher-level classification of the Family Pteropodidae.
