Parocnus dominicanus sp. nov. represents a new species of megalonychid ground sloth from theAltagracia Province of southeastern Dominican Republic. Specimens of multiple individuals, including oneassociated partial skeleton, were recovered from two separate underwater caves in the Parque Nacional delEste through collaborations with museums and cave divers between 2009–2013. Parocnus dominicanus sp.nov. is distinguished by its small size compared to that of P. serus, with percent differences in limb elementlengths ranging from 13−24%. Numerous cranial and post-cranial elements also exhibit morphological characterstates that are not attributable to size variations. The recovery of multiple individuals within each localitydemonstrates a size dimorphism, possibly sexual, which parallels patterns exhibited by P. serus. The twospecies are also geographically distinct, with no examples of co-occurrence at any localities to date. Parocnusdominicanus sp. nov. and P. serus share character states that are distinct from those of the Cuban species, P.browni, and which suggest differential usage of the forelimb. The exact age of the specimens described here isunknown, however, Parocnus has been dated to the Holocene in Haiti.http://zoobank.org/urn:lsid:zoobank.org:pub:12E495D3-E261-4522-9854-D3B4C2D5FFB8

A New Species

A review of the literature at large and the field photographic record of the senior author of this study indicate that there are several undescribed species of Aristolochia in Hispaniola (Dominican Republic and Haiti), related to A. bilobata. Here we show that A. mirandae is a synonym of A. bilobata and that what appears as A. bilobata in Marión H. (2011: 76–77) is a new species here described as Aristolochia adiastola. In addition, two new species, A. bonettiana and A. marioniana, also related to A. bilobata, are described and illustrated herein.

A New Species

Abstract A new species of Hawaiian finch is described from two fossil maxillae recovered from Holocene lacustrine sediments in Makauwahi Cave, island of Kaua‘i. The new species is assigned to Loxioides on the basis of characters defined in a previous study of drepanidine phylogeny. The maxilla of the new species resembles that of L. bailleui (the only other member of the genus) in its distinctly foreshortened shape, but differs in size and several qualitative characters. The species was sympatric with Loxioides cf. bailleui during the Holocene on Kaua‘i. Like L. bailleui, it may have been a resource specialist feeding mainly on leguminous pods. The radio-carbon chronology of the Makauwahi site indicates that the species became extinct in the late Holocene and, more tentatively, that it may have survived well beyond the time when humans first discovered and colonized Kaua‘i.

A New Species

We describe a new species of forest frog in the genus Platymantis from New Britain Island, Bismark Archipelago, Papua New Guinea. The new species is a morphologically cryptic form that has masqueraded for almost four decades under the name P. schmidti (formerly P. papuensis schmidti, Brown & Tyler, 1968). The new species is microsympatric with the geographically widespread P. schmidti at two known localities. We diagnose the new species on the basis of its distinctive advertisement call and slight but consistent differences in body size and proportions. Calling males of the new species appear to prefer more elevated perches than do males of P. schmidti and the new species may exhibit a greater extent of sexual size dimorphism.

A new species of previously monotypic genus of flea beetles (Coleoptera: Chrysomelidae: Galerucinae: Alticini), Bonfilsus Scherer 1967, is described from the Dominican Republic. This is the first record of Bonfilsus from the island of Hispaniola. The new species is compared to the only known species of the genus [B. subpubenscens (Bechyne)] and its distinguishing features as well as other morphological characters are illustrated and described.

A New Species

A new species, Stropharia acanthostipitata, is here described from the Dominican Republic and French Guiana based on morphological and molecular ITS/LSU analyses. It is distinguished by a dry, smooth and hygrophanous pileus with minute and fugacious velar remnants at the pileus margin, exannulate stipe, brown lamellae, presence of chrysocystidia on both edge and face of lamellae, and the occurrence of acanthocytes all over the stipe surface.
