The frog genus Pleurodema Tschudi, 1838 is distributed from Panama throughout South America to southern Chile and Argentina and currently is represented by 15 species, of which 10 have been recorded in Argentina (Faivovich et al. 2012). Recently, Valetti et al. (2009) re-described the tetraploid species P. kriegi and described a related cryptic species, the octoploid Pleurodema cordobae. These species are endemic of the Sierra Grande of Córdoba (Ferraro & Casagranda 2009; Valetti et al. 2009; Valetti et al. 2011) and together with the tetraploid P. bibrioni comprise a clade of polyploid cryptic species within the genus (Faivovich et al. 2012). The external morphology has been described for the tadpoles of P. bibrioni and P. kriegi by Kolenc et al. (2009), but the tadpole of P. cordobae remains undescribed. The aim of this work is to describe the larval external morphology and oral disc of new species P. cordobae.

External Morphology

The genus Gastrodynerus is here revised based on external morphology and male genitalia. Bohart (1984) proposed Gastrodynerus as a new genus with three species: G. vanduzeei (Bohart 1948), G. searsi Bohart, 1984, and G. stangei Bohart, 1984. Later, Rodriguez-Palafox (1996) added G. tacubayae (de Saussure, 1857). Herein, we describe four new species from Central America and South America: G. guatemalensis sp. nov.; G. barretti sp. nov.; G. aimara sp. nov. and G. yungaensis sp. nov. After this taxonomic revision, the Gastrodynerus includes eight species widely distributed in the New World. An identification key is provided for all of the species.

Morphological Differences

The tabanid tribe Diachlorini (Diptera) is the most genus-rich tribe in the Tabanidae; the tribe is cosmopolitan, but the greatest species richness and morphological diversity are found in the Australasian and Neotropical Regions. A new arrangement for the species of Acellomyia González is given; Acellomyia lauta (Hine) is transferred to a new genus, Montismyia gen.n., based on its morphological differences from Acellomyia and geographical distribution. The morphological differences between Acellomyia and Montismyia gen. n. are discussed. Two new species, Acellomyia casablanca sp.n. and Acellomyia puyehue sp.n., are described from specimens collected in southern Chile. Comparison of the morphology of Acellomyia paulseni mapuche (Coscarón & Philip) stat.nov. indicate that they should be elevated to species rank. A key to species of Acellomyia is provided and diagnostic characters are illustrated.

The monotypic genus Metasiphonella, originally described from Costa Rica, is now formally recorded from South America with a new species from Brazil—M. amorimi sp. nov. The taxonomic revision includes a detailed description of adult external morphology, female and male terminalia, and the egg stage for all species. A lectotype of M. magnifica Duda is designated and new country records are given.

A New Species

Based on differences in hemipenial morphology we recognize two species of anoles related to Anolis polylepis: Anolis polylepis (Pacific versant of central and southern Costa Rica and western Panama, excluding the Osa Peninsula) and a species described herein which is restricted to the Osa Peninsula. The two species differ in hemipenial morphology (hemipenis bilobed in A. polylepis versus unilobed in the species from the Osa Peninsula) but show no discernable differences in external morphology (i.e., morphometrics, scalation, coloration, male dewlap). We therefore consider them to be cryptic species. At the neck of the Osa Peninsula where the ranges of the two species meet we detected a narrow (about 1 km wide) hybridization zone in which only individuals with an intermediate hemipenial morphology occur.

AbstractThe new species Calvitimela austrochilenis Fryday and Tephromela superba Fryday are described: the former from several collections from southern Chile and one from Marion Island, and the latter from southern South America (including the Falkland Islands), Campbell Island, (New Zealand), and Antarctica. Four new combinations are also made in Tephromela: T. atrocaesia (Nyl. ex Cromb.) Fryday from Îles Kerguelen, Heard Island, South Georgia, and southern South America; T. atroviolacea (Flot.) Fryday from southern South America and Îles Kerguelen; T. lirellina (Darb.) Fryday from only southern South America; and T. skottsbergii (Darb.) Fryday, which is shown to be an earlier name for T. austrolitoralis (Zahlbr.) Kalb & Elix, from throughout the region. Lectotypes are selected for Lecanora atrocaesia and L. atroviolacea. The systematic placement of Tephromela eatonii (Cromb.) Hertel from Kerguelen, Marion Island and Bouvetøya is also discussed but the species is retained in Tephromela.

Seven new species of the economically important sharpshooter genus Acrogonia Stål are described and illustrated: A. falcata sp. nov. (French Guiana and state of Amazonas, Brazil), A. felixi sp. nov. (department of Loreto, Peru), A. quintasi sp. nov. (state of Pará, Brazil), A. distincta sp. nov. (state of Amazonas, Brazil), A. dentata sp. nov.

(province of Pastaza in Ecuador and state of Amazonas in Brazil), and A. lobulata sp. nov. (province of Orellana, Ecuador). In addition to the external morphology, color pattern, and male genitalia, detailed descriptions and illustrations of the female genitalia are provided for three of the new species (A. dentata, A. luizi, and A. lobulata). Females of the other four new species are unknown. Acrogonia includes now 39 species, being among the most species-rich genera of the Proconiini.

The marine gastropod genus Struthiochenopus appears first in the late Cretaceous of the Antarctic Peninsula. Until the Oligocene only one or two species were extant at the same time. This changed drastically in the early Miocene when at least three species were living coevally in southern South America. A possible fourth early Miocene species, Struthiochenopus sp., is known from Ipún Island, Chile, but its identification remains unclear. Another taxon, S. echtleri new species, described from Neogene deposits of Mocha Island, Chile, has no precise age available but it is likely the latest survivor of the genus.

The Neotropical genus Carrerapyrgota Aczél is restricted to the South America (Brazil and Argentina). The genus is composed of two previously described species, which are revised herein: C. miliaria Aczél and C. personata (Lutz & Lima). Two new Brazilian species are described: C. aczeli from São Paulo and C. bernardii from Bahia. Illustrations of the external morphology of adults and male and female terminalia are also included. An identification key to the species is presented, as well as a brief discussion of the biology and distribution of the genus.

A new species ofAnolislizard from the Andean slopes of southwestern Colombia and northwestern Ecuador, from between 1187 and 2353 m in elevation, is described. The new species can be distinguished from otherAnolisin squamation, cranial osteology, hemipenial morphology, and nuclear and mitochondrial DNA. The new species is sister toAnolisaequatorialis, and it is suggested that previous records ofA.aequatorialisin Colombia correspond to the new species described herein.
