Neotropical Osmylidae larvae (Insecta,Neuroptera): description of habitats and morphology

ABSTRACT

The larval stages of the genus Kempynus Navás, 1912 Navás, L. (1912), ‘Insectos neurópteros nuevos o poco conocidos’, Memorias de la Real Academia de Ciencias y Artes de Barcelona, 10, 135–202. [Google Scholar] (probably K. falcatus Navás, 1912 Navás, L. (1912), ‘Insectos neurópteros nuevos o poco conocidos’, Memorias de la Real Academia de Ciencias y Artes de Barcelona, 10, 135–202. [Google Scholar] based on the presence of synchronic and sympatric adults) are described for the Neotropical Region for the first time, and the larval stages of Isostenosmylus pulverulentus (Gerstaecker, 1893 Gerstaecker, C.E.A. (1893), ‘Ueber neue und weniger gekannte Neuropteren aus der familie Megaloptera Burm’, Mitt[h]eilungen aus dem Naturwissenschaftlichen Verein für Neu-Vorpommern und Rugen, 25, 93–173. [Google Scholar]) are redescribed. The external morphology of third-instar larvae of both species and their habitats are described and compared. Kempynus sp. is a water-dependent species and can be considered semi-aquatic, whereas I. pulverulentus larvae are terrestrial and live in undergrowth vegetation. The first key to identification of Neotropical Osmylidae larvae is provided, based on third-instar larvae of both species.     

Paralarval development,abundance, and distribution of Pterygioteuthis hoylei (Cephalopoda: Oegopsida: Pyroteuthidae) in the Gulf of California,México

The morphology and ecology of paralarvae (PL) through to the juvenile stages are unknown in most cephalopod species in spite of their importance as indicators of biodiversity, of adult spawning grounds, and as key basis for fisheries management programs. We describe, for the first time, the morphological development of Pterygioteuthis hoylei (Pfeffer 1912 Pfeffer, G. 1912. Die Cephalopoden der Plankton-Expedition. Zugleich eine monographische übersicht der Oegopsiden Cephalopoden. Ergebnisse der Plankton-Expedition der Humboldt-stiftung, 2: 1–815.  [Google Scholar]) and used cytochrome C oxidase for genetic identification of specimens, linking PL with both juveniles and adults. Pterygioteuthis hoylei represents the most abundant species of squid in oblique plankton collections in the Gulf of California, México. PL were collected in plankton tows made in the Gulf of California from 2004 to 2007. Almost all morphological features followed an increasing size/count trend. Most specimens were collected during March–May, accounting for 71.8% of total cephalopod paralarval abundance, and in November (13.5%). Size, abundance and distribution analyses indicate a high abundance of recently hatched PL (1.1–2.0 mm mantle length) off Bahía Concepción to Bahía de La Paz in these months along with the highest abundance of juveniles and adults in the same area. These results indicate that reproductive activity of P. hoylei takes place in the southern Gulf of California in late winter to early spring, and in November, representing an important spawning and hatching area for this species.     

Description of two new species and phylogenetic reassessment of Perelleschus O’Brien & Wibmer, 1986 (Coleoptera: Curculionidae), with a complete taxonomic concept history of Perelleschus sec. Franz & Cardona-Duque, 2013

Parmelioid lichens form the largest monophyletic group within the Parmeliaceae, a family distributed worldwide. The genus Parmelina was described by Hale (1976a) Hale, M. E. Jr. 1976a. A monograph of the lichen genus Parmelina Hale (Parmeliaceae). Smithsonian Contributions to Botany, 33: 1–60.  [Google Scholar] accommodating species from both hemispheres. We have employed parsimony, Bayesian and maximum likelihood analyses of a combined data set of nu ITS, LSU and mt SSU rDNA sequences to (1) test the monophyly of Parmelina and (2) to elucidate the generic status and phylogenetic position of the Australasian species. Twenty-one new sequences were generated in this study. Our results provide evidence that Parmelina is polyphyletic and the species fall into two major well-supported groups (Groups I and II). The Australasian species of Parmelina and two species of Canoparmelia (C. pruinata and C. macrospora) form Group I, which is nested within the parmotremoid genera of Parmeliaceae, Parmelina species from the northern hemisphere including those from western North America and the Mediterranean basin form a monophyletic group (Group II), which is sister to the East Asian temperate genus Myelochroa. Morphological and chemical features were reevaluated considering this observed phylogeny. Some morphological features like lobe morphology, several traits in the excipulum and geography are useful in characterizing the monophyletic lineage of the Australasian Parmelina/Canoparmelina species. This lineage is described as the new genus Austroparmelina. Thirteen new combinations in the new genus are proposed.

Currently, Phylloicus has 55 extant species, 19 of which are recorded from Brazil, and a fossil species from Dominican amber. In this paper, a new species of Phylloicus is described and illustrated from specimens collected in Amazonas State, Brazil. This new species has peculiar hind wing venation, with vein R₄ attached basally to the base of R₂₊₃. Therefore, a modified diagnosis to the genus is presented to include Phylloicus dumasi sp. nov.

Cryptic diversity among the achaetous Marionina (Annelida,Clitellata, Enchytraeidae)

This study investigates the diversity and taxonomy of a mainly marine group of species lacking chaetae currently assigned to the genus Marionina. This achaetous group includes four nominal species: M. achaeta (Hagen, 1954 Hagen, G. 1954. Michaelsena achaeta nov. sp., ein neuer mariner Oligochaet aus der Kieler Bucht. Faunistische Mitteilungen aus Norddeutschland, 1: 12–13.  [Google Scholar]), M. achaeta sensu Lasserre, 1964 Lasserre, P. 1964.

Procés-Verbaux des Séances de la Société Linnéenne de Bordeaux, 101: 87–91.  [Google Scholar], M. nevisensis Righi & Kanner, 1979 Righi, G. and Kanner, E. 1979. Marine Oligochaeta (Tubificidae and Enchytraeidae) from the Caribbean Sea.

Marine fauna of County Wexford. 1 – Littoral and brackishwater Oligochaeta. The Irish Naturalists' Journal, 19: 418–422.  [Google Scholar]. As Lasserre's (1964 Lasserre, P. 1964. Notes sur quelques oligochètes Enchytraeidae présents dans les plages du Bassin d’Arcachon. Procés-Verbaux des Séances de la Société Linnéenne de Bordeaux, 101: 87–91.  [Google Scholar]) M. achaeta appears to be morphologically different from its (then) senior homonym M. achaeta (Hagen, 1954 Hagen, G. 1954. Michaelsena achaeta nov. sp., ein neuer mariner Oligochaet aus der Kieler Bucht. Faunistische Mitteilungen aus Norddeutschland, 1: 12–13.  [Google Scholar]), the replacement name M. nothachaeta nom. nov. is proposed for it. We studied the genetic and morphological diversity of achaetous specimens of Marionina collected in Florida, the Great Barrier Reef, New Caledonia, Sweden, England and the Bahamas. The collection localities are almost all supralittoral and often brackish-water habitats. Parts of the mitochondrial genes 12S, 16S, COI and the nuclear genes 18S, 28S and ITS were analysed to assess the genetic variation and phylogeny of the achaetous Marionina species. The molecular data reveal one monophyletic group of 11 separately evolving lineages, and between these lineages, K2P distances in the barcoding gene COI vary between 5.4 and 25.0%. On a morphological basis, the lineages could be assigned to seven different groups (morphotypes), of which only two could be identified as described nominal taxa: M. nevisensis s. lat. (several lineages) and M. nothachaeta. Since the former taxon appears to be a complex of cryptic species around the world and the original type material no longer exists, a neotype from the Caribbean was designated for M. nevisensis s. str. The remaining achaetous lineages represent five morphologically distinct species that are left unnamed, awaiting finer morphological scrutiny and detailed comparisons with new collections of M. achaeta and M. arenaria. Summing up, the group of achaetous Marionina now seems to contain up to 13 different species, seven of which are yet to be formally described and named.     

Molecular identity,morphology and taxonomy of the Rhynchospio glutaea complex with a key to Rhynchospio species (Annelida,Spionidae)

Rhynchospio glutaea (Ehlers, 1897 Ehlers, E. 1897. Polychaeten. Ergebnisse der Hamburger Magalhaensischen Sammelreise 1892/93. L. Friederichsen & Co., Hamburg, Germany. [Google Scholar]), Rhynchospio arenincola Hartman, 1936 Hartman, O. 1936. New species of Spionidae (Annelida Polychaeta) from the coast of California. University of California Publications in Zoology 41, 45–52. [Google Scholar] and Rhynchospio arenincola asiatica Chlebovitsch, 1959 Chlebovitsch, V.V. 1959. Species of Polychaeta worms from the Kurile Islands, which are new or recorded for the first time in the USSR fauna. Zoologichesky Zhurnal 38, 167–181. [Google Scholar], originally described from Strait of Magellan, California, and South Kurile Islands respectively, appear similar to each other in adult morphology. These species and subspecies have been considered by some authors as subjective synonyms and are here referred to as members of the R. glutaea complex. Sequence data of four gene fragments (2465 bp in total) of the mitochondrial 16S rDNA, nuclear 18S and 28S rDNA, and Histone 3 have shown that R. glutaea complex individuals from the South West Atlantic (Argentina), North East Pacific (British Columbia and Oregon) and North West Pacific (South Korea) were genetically distant and not conspecific. These data also indicate that R. arenincola from North America and R. aff. asiatica from South Korea are more closely related to each other, and both are closer to R. glutaea from South America than to R. nhatrangi from Vietnam: nhatrangi (glutaea (arenincola-aff. asiatica)). Adults of the R. glutaea complex are hermaphrodites and the arrangement of gametes is suggested to be a crucial reproductive character for distinguishing these species. Based on this character, two species of the complex are apparent in the North West Pacific: R. asiatica Chlebovitsch, 1959 Chlebovitsch, V.V. 1959. Species of Polychaeta worms from the Kurile Islands, which are new or recorded for the first time in the USSR fauna. Zoologichesky Zhurnal 38, 167–181. [Google Scholar] stat. nov. from the Kurile Islands (not analysed here) and an unnamed species from the mainland coast of Asia (here referred to as R. aff. asiatica). Adult morphology of R. asiatica stat. nov. is briefly described and illustrated. The lectotype and the type locality of the species on Iturup Is. are established for the first time. An identification key is provided to the 10 currently recognized Rhynchospio species.
