We describe three new species of Pristimantis leaflitter frogs from the upper Amazon basin of Ecuador: Pristimantis achuar, Pristimantis altamnis, and Pristimantis kichwarum. Each of these new species was previously considered to be part of a single species, formerly known as Eleutherodactylus ockendeni (Boulenger) morph B. However, analysis of DNA sequences together with examination of the morphology of more than 600 specimens from Ecuador reveals that multiple species were confused under the same name. The morphological differences among the three new species are subtle but consistent: presence or absence of a black canthal stripe and/or supratympanic ridge, snout-vent length, and ventral colouration. The three species are generally allopatric and geographically restricted, although at some localities two of the species occur sympatrically.Describimos tres especies nuevas de ranas del sotobosque de la cuenca Amazónica Ecuatoriana: Pristimantis achuar, Pristimantis altamnis y Pristimantis kichwarum. Estas especies fueron consideradas antes como una sola especie bajo el nombre Eleutherodactylus ockendeni (Boulenger) morfo B. Sin embargo, el análisis de secuencias de ADN y la examinación de la morfología de más que 600 especímenes Ecuatorianos indican que en realidad existen tres especies. Sus diferencias morfológicas son sutiles pero constantes: presencia o ausencia de una raya cantal negra y/o de un pliegue supratimpánico y su coloración ventral. Las tres especies tienen distribuciones alopátricas y distintas aunque en algunas localidades se puede encontrar dos de las tres especies juntas.

Three New Species

We describe three new species of minute salamanders, genusThorius, from the Sierra Madre del Sur of Oaxaca, Mexico. Until now only a single species,T. minutissimus, has been reported from this region, although molecular data have long shown extensive genetic differentiation among geographically disjunct populations. AdultThorius pinicolasp. nov.,T. longicaudussp. nov., andT. tlaxiacussp. nov. are larger thanT. minutissimusand possess elliptical rather than oval nostrils;T. pinicolaandT. longicaudusalso have longer tails. All three new species occur west of the range ofT. minutissimus, which has the easternmost distribution of any member of the genus. The new species are distinguished from each other and from other namedThoriusin Oaxaca by a combination of adult body size, external morphology and osteology, and by protein characters (allozymes) and differences in DNA sequences. In addition, we redescribeT. minutissimusand a related species,T. narisovalis, to further clarify the taxonomic status of Oaxacan populations and to facilitate future studies of the remaining genetically differentiatedThoriusthat cannot be satisfactorily assigned to any named species. Populations of all five species considered here appear to have declined dramatically over the last one or two decades and live specimens are difficult to find in nature.Thoriusmay be the most endangered genus of amphibians in the world. All species may go extinct before the end of this century.

Molecular Clock Analysis

AbstractWe assessed the taxonomy and phylogenetic relationships of Hawaiian species of the neotropical genus Lobariella. A single species was previously reported from the archipelago, the widespread neotropical L. crenulata. We targeted three loci of the mitochondrial and nuclear ribosomal rDNA gene cistron (mtSSU, nuLSU, ITS) and also performed a molecular clock analysis. Our results show that L. crenulata s. str. is seemingly present in the archipelago based on older herbarium collections. However, Hawaiian Lobariella includes three additional, presumably endemic, species unrelated to L. crenulata and new to science: L. flynniana Lücking, Moncada & C. W. Sm., with richly branched marginal phyllidia giving the thallus a fruticose appearance; L. robusta Lücking, Moncada & C. W. Sm., with a rather thick thallus and abundant, large, laminal phyllidia; and L. sandwicensis Lücking, Moncada & C. W. Sm., with a delicate thallus producing apothecia. Lobariella flynniana represents a novel morphotype within the genus, thus far known only from Hawaii. All three species are very closely related, forming a well-supported, monophyletic clade in spite of their morphological differences, suggesting local micro-radiation. Molecular clock analysis indicates that this clade colonized the islands between 1–8 mya and diverged between 0–2 mya. We interpret recent colonization as one of the main reasons why this clade has not diversified further.

The species of Charaxwere reviewed by Lucena (1987) who a little later (1989) added three new species to the genus. Examination of recently collected specimens from museum collections documented the more extensive geographic distribution for most species and revealed the existence of a new species in which superficial neuromasts were discovered and are herein described. These skin structures were also detected in C. metae Eigenmann, 1922. Anal- and pelvic-fin hooks previously observed only on the anal-fin of one species of the genus are described herein in some other species. Charax unimaculatus Lucena is considered a junior synonym of C. michaeli Lucena. All the species are redescribed and the new species described.

Three New Species

The current paper expands knowledge of the genus Coddingtonia Miller, Griswold & Yin, 2009. Based on morphological characters and molecular data, three species are documented as new to science: C. erhuan Feng & Lin, sp. nov. (♀) from China, C. lizu Feng & Lin, sp. nov. (♀) from China, and C. huifengi Feng & Lin, sp. nov. (♂♀) from Indonesia. The type of C. euryopoides Miller, Griswold & Yin, 2009 is also reexamined. DNA sequences (COI), detailed illustrations of habitus, male palp and epigyne are provided for these four species, as well as a key and a distribution map for Coddingtonia species.

Three New Species

The monotypic tachinid genus Opsozelia Townsend, 1919 (Diptera: Tachinidae) is synonymized with ZeliaRobineau-Desvoidy 1830, syn. nov. The single species of Opsozelia, O. discalis Townsend, 1919, is redescribed as Zelia discalis, comb. nov., based on examination of the holotype from Guyana and additional material from Suriname, Brazil and Paraguay. Three new species of Zelia similar to Z. discalis are described from Brazil: Z. magnasp. nov., Z. guimaraesisp. nov. and Z. formosasp. nov. These four species are treated informally as the Zelia discalis species group. An identification key to the species of this species group is provided based on male specimens. Descriptions and illustrations are provided for the male terminalia of all species and for the female terminalia of one species, Z. guimaraesi.

Microscopy Examination

The genus Setosella included to date six species. After revision, only four of these species were retained, i.e. S. vulnerata, S. cavernicola, S. folini and S. spiralis. The remaining two species were tentatively placed in Woodipora, W.? antilleana n. comb., and Andreella,  A.? fragilis n. comb. On the other hand, scanning electron microscopy examination of Mediterranean material, revealed the presence of three new species previously included in species complexes: S. cyclopensis n. sp. from the open-shelf, S. rossanae n. sp. from submarine caves, and S. alfioi n. sp. from deep-waters. The diagnosis of the genus was amended to include the occurrence of kenozooids in S. cyclopensis n. sp. and S. cavernicola, and of free-living ring-shaped and scorpioid colonies in S. folini and S. alfioi n. sp. All the seven species n           1ow in Setosella have present-day representatives; the geographic distribution of the genus 1sinian of southern Italy and insular Greece, with only three species occasionally and discontinuously reported. All species are able to produce numerous, subsequent intramural buds and morphological differences seem to be consistently associated with exploitation of particular habitats and substrata.

Three New Species

The European and Mediterranean species of the Acalyptris platani and A. staticis groups are revised, with respectively four and six species. Three new species are described: A. pistaciae Van Nieukerken sp. n. (from Greece, Cyprus and Turkey, on Pistacia) in the platani group, A. limoniastri Van Nieukerken sp. n. (from Algeria and Tunisia, associated with Limoniastrum) and A. lesbia Van Nieukerken & Hull sp. n. (from Greece: Lesvos, on Limonium gmelini) in the staticis group. Lectotypes are selected for A. minimella (Rebel, 1924) and A. staticis (Walsingham, 1908). The European species of the A. platani group are leafminers on Anacardiaceae, Platanaceae and Loranthaceae, the species of the A. staticis group feed on Plumbaginaceae, except A. pyrenaica A. & Z. Laštůvka, for which the host is unknown, but likely to belong to another family. Immatures are described for five species, final instar larvae and pupal exuviae for all species in the A. platani group and for A. lesbia. Larvae and pupae of the latter species differ markedly from the A. platani group. Recorded parasitoids are listed. CO1 barcodes are provided for seven species. The groups are phylogenetically not very close; the monophyly of Acalyptris and the phylogeny on the basis of CO1 (mt-DNA) sequences are discussed.
