Wild Species 2010 the GENERAL STATUS of SPECIES in CANADA
Wild Species 2010 THE GENERAL STATUS OF SPECIES IN CANADA Canadian Endangered Species Conservation Council National General Status Working Group This report is a product from the collaboration of all provincial and territorial governments in Canada, and of the federal government. Canadian Endangered Species Conservation Council (CESCC). 2011. Wild Species 2010: The General Status of Species in Canada. National General Status Working Group: 302 pp. Available in French under title: Espèces sauvages 2010: La situation générale des espèces au Canada. ii Abstract Wild Species 2010 is the third report of the series after 2000 and 2005. The aim of the Wild Species series is to provide an overview on which species occur in Canada, in which provinces, territories or ocean regions they occur, and what is their status. Each species assessed in this report received a rank among the following categories: Extinct (0.2), Extirpated (0.1), At Risk (1), May Be At Risk (2), Sensitive (3), Secure (4), Undetermined (5), Not Assessed (6), Exotic (7) or Accidental (8). In the 2010 report, 11 950 species were assessed. Many taxonomic groups that were first assessed in the previous Wild Species reports were reassessed, such as vascular plants, freshwater mussels, odonates, butterflies, crayfishes, amphibians, reptiles, birds and mammals. Other taxonomic groups are assessed for the first time in the Wild Species 2010 report, namely lichens, mosses, spiders, predaceous diving beetles, ground beetles (including the reassessment of tiger beetles), lady beetles, bumblebees, black flies, horse flies, mosquitoes, and some selected macromoths. The overall results of this report show that the majority of Canada’s wild species are ranked Secure. -

BIOLOGICAL RESULTS OF THE UNIVERSITY OF MIAMI DEEP-SEA EXPEDITIONS. 55. THE LARVAL STAGES OF HOMOLA BARBATA (FABRICIUS) (CRUSTACEA, DECAPODA, HOMOLIDAE) REARED IN THE LABORATORyl A. L. RICE British Museum (Natural History), Cromwell Road, London, S.W. 7, England AND ANTHONY J. PROVENZANO, JR. University of Miami, Rosenstiel School of Marine and Atmospheric Sciences ABSTRACT Larvae yielded by a female collected off Yucatan were reared to the seventh, and final, zoeal stage at 20°C and 36.2%0 salinity. The larvae, the first complete series available of any species of the family, are described and illustrated. Comparison of the reared larvae with others attributed to the same species but captured in Mediterranean and South African waters confirmed the morphological differences which previously had led to sug- gestions of specific or subspecific separation of the parent populations. Examination of adult material failed to reveal positive evidence of specific status of the separated populations. The setation of the uropodal endopods in Homola appears in the third zoeal stage, earlier than for any other decapod known. Recent studies of larval forms tend to confirm the view that the Homolidae are related to the Raninidae and are close to the line of descent of the true crabs, and that the family is well separated from both the typical Anomura and the much more primitive Dromiidea. INTRODUCTION Homola barbata has been recorded in the eastern and western North Atlantic, in the Mediterranean, and in the South Atlantic near South Africa. Throughout its range (Fig. 1), H. barbata is the only recognized repre- sentative of the genus, except off the east coast of North America where a closely related species, H. -

Over 10,500 names are treated including 6,793 valid species and subspecies (with 1,907 primary synonyms), 1,271 genera and subgenera (with 393 primary synonyms), 93 families and 38 superfamilies. Nomenclatural and taxonomic problems are reviewed in detail, and many resolved. Detailed notes and references are provided where necessary. The constitution of a large number of families and superfamilies is discussed in detail, with the positions of some taxa rearranged in an attempt to form a stable base for future taxonomic studies. This is the first time the nomenclature of any large group of decapod crustaceans has been examined in such detail.

Basal Position of Two New Complete Mitochondrial Genomes of Parasitic
Hua et al. Parasites & Vectors (2018) 11:628 https://doi.org/10.1186/s13071-018-3162-4 RESEARCH Open Access Basal position of two new complete mitochondrial genomes of parasitic Cymothoida (Crustacea: Isopoda) challenges the monophyly of the suborder and phylogeny of the entire order Cong J. Hua1,2, Wen X. Li1, Dong Zhang1,2, Hong Zou1, Ming Li1, Ivan Jakovlić3, Shan G. Wu1 and Gui T. Wang1,2* Abstract Background: Isopoda is a highly diverse order of crustaceans with more than 10,300 species, many of which are parasitic. Taxonomy and phylogeny within the order, especially those of the suborder Cymothoida Wägele, 1989, are still debated. Mitochondrial (mt) genomes are a useful tool for phylogenetic studies, but their availability for isopods is very limited. To explore these phylogenetic controversies on the mt genomic level and study the mt genome evolution in Isopoda, we sequenced mt genomes of two parasitic isopods, Tachaea chinensis Thielemann, 1910 and Ichthyoxenos japonensis Richardson, 1913, belonging to the suborder Cymothoida, and conducted comparative and phylogenetic mt genomic analyses across Isopoda. Results: The complete mt genomes of T. chinensis and I. japonensis were 14,616 bp and 15,440 bp in size, respectively, with the A+T content higher than in other isopods (72.7 and 72.8%, respectively). Both genomes code for 13 protein-coding genes, 21 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (rRNAs), and possess a control region (CR). Both are missing a gene from the complete tRNA set: T. chinensis lacks trnS1 and I. japonensis lacks trnI. Both possess unique gene orders among isopods. -

E-mail: [email protected] *Corresponding author. Abstract The squat lobster, Munidopsis lauensis Baba & de Saint Laurent, 1992, is recorded from Taiwan for the first time. This species was previously known only from deep-sea hydrothermal vents in the South-West Pacific but it was now found at a deep-sea cold seep site off southwestern Taiwan. The identity of the Taiwanese material is confirmed by comparison of sequences from the barcoding gene COI. Munidopsis lauensis can be easily separated from other congeners in Taiwanese waters by the eyes bearing a strong mesiodorsal spine and a small mesioventral spine, smooth carapace, fingers of the cheliped distally spooned and fixed finger without a denticulate carina on the distolateral margin. -

Surveys were done by the Shinkai 2000 on the Hatoma and Dai-yon Yonaguni KnoUs in the southern Okinawa Trough. On the Hatoma Knoll, S. crosnieri inhabited areas (temp. 4.(>-6.2°C) about 0.2-2 m away from the active vent (temp. 30f C).

Guide to Crustacea
46 Guide to Crustacea. Order 2.—Decapoda. (Table-cases Nos. 9-16.) The gills are arranged typically in three series—podo- branchiae, arthrobranchiae, and pleurobranchiae. Only in the aberrant genus Leucifer are the gills entirely absent. The first three pairs of thoracic limbs are more or less completely modified to act as jaws (maxillipeds), while the last five form the legs. This very extensive and varied Order includes all the larger and more familiar Crustacea, such as Crabs, Lobsters, Crayfish, FIG. 30. Penaeus caramote, from the side, about half natural size. [Table-case No. 9.] Prawns, and Shrimps. From their greater size and more general interest, it is both possible and desirable to exhibit a much larger series than in the other groups of Crustacea, and in Table-cases Nos. 9 to 16 will be found representatives of all the Tribes and of the more important families composing the Order. On the system of classification adopted here, these tribes are grouped under three Sub-orders :— Sub-order 1.—Macrura. „ 2.—Anomura. ,, 3.—Brachyura. Eucarida—Decapoda. 47 SUB-ORDER I.— MACRURA. (Table-cases Nos. 9-11.) The Macrura are generally distinguished by the large size of the abdomen, which is symmetrical and not folded under the body. The front, or rostrum, is not united with the " epistome." The sixth pair of abdominal appendages (uropods) are always present, generally broad and flattened, forming with the telson, a " tail-fan." The first Tribe of the Macrura, the PENAEIDEA, consists of prawn-like animals having the first three pairs of legs usually chelate or pincer-like, and not differing greatly in size.
