New distribution records for Canadian Aleocharinae (Coleoptera,Staphylinidae), and new synonymies for Trichiusa

Fifty-four new Canadian provincial records of aleocharine beetles (Staphylinidae), including three new Canadian records and one new North American record, are presented. Of these, 33 are new provincial records for Saskatchewan, 14 for Alberta, two for British Columbia, three for Manitoba, two for the Northwest Territories and one for the Yukon Territory. The following are new Canadian records: Trichiusa pilosa Casey [formerly reported from Nova Scotia and Ontario as Trichiusa postica Casey], Acrotona recondita (Erichson) and the adventive Palaearctic Atheta nigra (Kraatz), which is also a new North American record. Bionomics information and new locality records are provided. The following new synonyms of Trichiusa pilosa Casey are established: Trichiusa atra Casey, Trichiusa monticola Casey, Trichiusa parviceps Casey, and Trichiusa postica Casey. The numbers of Aleocharinae remaining to be discovered in Canadian provinces and territories are discussed.     

Ein neues clerodan-derivat sowie weitere inhaltsstoffe aus der gattung Macowania ag

The roots of M. corymbosa afford three new benzofuran derivatives very closely related to leysseralangelicate isolated from the related genus Leyssera. The aerial parts of M. glandulosa contain, besides labdanolic acid, a new cis-clerodane derivative, its structure being elucidated by spectroscopic methods and by chemical reactions. The roots of a further Macowania species closely related to M. hamata afford a new ester related to m-thymol.     

New and poorly known acrotretid brachiopods (Class Lingulata) from the Cedaria-Crepicephalus zone (late Middle Cambrian) of the Great Basin, USA

Seven new late Middle Cambrian (Cedaria-Crepicephalus zone) acrotretid species are described from the Great Basin, USA. The species belong to five genera of which Lensotreta is new. The following new species are described: Anabolotreta? glabra, Anabolotreta mogota, Canthylotreta crista, Dactylotreta elegantula, Lensotreta perplexa, Opisthotreta transversa, and Opisthotreta indistincta. The shell structure of Canthylotreta is described for the first time based on new material of the type species Canthylotreta marjumensis and of the new species C. crista. The shell of Canthylotreta includes two types of shell fabric, camerate and columnar. Moreover, parts of the shell show transitional textures, supporting the view that the camerate shell structure may has originated from a columnar fabric. Picnotreta lophocracenta Robson and Pratt, 2001, recently described from western Newfoundland, is also described from the new occurrence in the Great Basin.     

A new genus of soft coral (Cnidaria,Octocorallia) from the Republic of Congo (Pointe-Noire Region)

A new genus of soft coral from the Republic of Congo is described, Complexum gen. n. Nine West African octocoral species previously described in the genus Alcyonium by Tixier-Durivault (1955) are referred to this new genus, and a new species is described and figured, Complexum pusillum sp. n. The new species is characterized by having encrusting growth form and abundant spiny clubs in the surface of the polyparium. It colonizes shallow calcareous rocky banks (5 to 20 m depth) existing in coastal water of the region of Pointe-Noire. Based on molecular phylogeny this new genus is well separated from Alcyonium species.     

Sumatrella chelonica gen. n., sp. n., a new remarkable genus and species from Indonesia,Sumatra (Acari,Uropodina, Oplitidae)

A new genus Sumatrella gen. n. is described and illustrated based on the new species Sumatrella chelonica sp. n. collected in Sumatra, Indonesia. The new genus belongs to the family Oplitidae based on its hypertrichous internal malae and the absence of strongly sclerotized structures on the dorsal shield. The new genus is closely related to the genus Chelonuropoda Sellnick, 1954 but the transverse furrow on ventral idiosoma close to coxae IV and the strongly sclerotized C-shaped dorsal line are missing in the new genus. These characters can be found in species of Chelonuropoda.     

Unusual assemblages of Late Cretaceous silicoflagellates from the Canadian Archipelago

Devon and Ellef Ringnes islands in the Canadian Arctic Archipelago contain well-preserved Santonian through early Campanian silicoflagellates. These occur in three unusual assemblages, which comprise three biostratigraphic zones. The oldest, the Vallacerta tumidula Partial Range Zone of Santonian age, contains an extremely variable microflora that includes species of the poorly-known genus Variramus, two new species of Cornua, and a new genus Umpiocha. The Schulzyocha ruppelii Range Zone of early Campanian age includes several species of the new genus Schulzyocha, reflecting quadrate silicoflagellate skeletal morphologies that lack a basal structure. The youngest assemblage includes the poorly-known species Cornua trifurcata, the nominative taxon of the C. trifurcata Partial Range Zone (proposed by McCartney et al., in press c; emended herein), which allows a correlation with a silicoflagellate-bearing sequence from the Horton River area, Northwest Territories of Canada. This report presents information on 24 silicoflagellate taxa, proposes 2 new genera, Schulzyocha and Umpiocha, and describes 13 new species and 1 new combination. All of these new taxa disappear by the top of the Campanian Cornua trifurcata Partial Range Zone. These assemblages reveal a new history of silicoflagellate evolution prior to the late Campanian, the period from which most of our prior knowledge about Cretaceous silicoflagellates was derived. The assemblages show progressive change from skeletons with highly variable morphologies to more stable silicoflagellate skeletal geometry. Two important Corbisema species, C. apiculata and C. archangelskiana, appear to be derived from separate lines within Cornua in the latest Santonian and early Campanian. The important Cretaceous genus Lyramula makes its first appearance at the beginning of the Campanian.     

Hispaniolan Hemilophini (Coleoptera,Cerambycidae, Lamiinae)

The Tribe Hemilophini (Lamiinae) is reviewed for Hispaniola and an identification key is provided. Fifteen species are now known from the island, including one new species of Adesmus (Adesmus fortunei from Pedernales and La Vega Provinces, Dominican Republic), one new species of Oedudes (Oedudes anulatus from Peravia and La Vega Provinces, Dominican Republic), and five new species of Calocosmus (Calocosmus contortus from San Cristóbal Province, Calocosmus punctatus from Peravia Province, Calocosmus rawlinsi from Elías Piña Province, Calocosmus robustus from La Vega Province, and Calocosmus thonalmus from La Altagracia Province, all in the Dominican Republic). Oedudes and Adesmus are new island and country records for Hispaniola and Dominican Republic, respectively. Calocosmus holosericeus Gahan is a new synonym of Calocosmus janus Bates. In addition to the new species, five new country records and four new island records are presented for Calocosmus.     

Lamprops donghaensis sp. n. (Crustacea,Cumacea, Lampropidae), a new species from Korean waters

A new species of Cumacea belonging to the genus Lamprops Sars was collected from the East Sea of Korea. This new species resembles Lamprops comatus Zimmer, Lamprops carinatus Hart, Lamprops flavus Harada, Lamprops pumilio Zimmer, Lamprops tomalesi Gladfelter, and Lamprops obfuscatus (Gladfelter) in lacking lateral oblique ridges on the carapace and lateral setae on the telson. The new species, however, is distinguished from its congeners by having a dorsal concave groove and a lateral rounded depressed area on pereonite 2. The new species is fully illustrated and compared with related species. A key to the world Lamprops species lacking lateral ridges on the carapace is also provided.     

New records,synonyms and combinations for oriental Sarcophagidae (Diptera), with updated checklists for Cambodia,India, Taiwan,Thailand and Vietnam

Faunistic records of 29 flesh fly species are presented, and the following new country-level records are provided: 12 species (Senotainia albifrons, Eremasiomyia macularis, Asceloctella calicifera, Pseudothyrsocnema caudagalli, Liosarcophaga dux, L. kohla, L. scopariiformis, L. tuberosa, Parasarcophaga misera, Sarcosolomonia harinasutai, S. shinonagai, Seniorwhitea princeps) new to Cambodia, one species (S. shinonagai) new to India, one species (Brachicoma devia) new to Taiwan, two species (Myorhina thinhi, L. tuberosa) new to Thailand, and two species (E. macularis, P. caudagalli) new to Vietnam. Based on critical revision of all published records and on new data presented herein, 215 species of Sarcophagidae are listed from Cambodia (16 species), India (138), Taiwan (63), Thailand (98) and Vietnam (49). One new subjective generic synonym is proposed: Shinonagaella Verves, 1997 = Lehisca Kurahashi and Tan, 2012, syn. nov. Altogether, total of 21 new subjective synonyms and 16 new combinations are proposed.     

Revision of the subgenus Tinotus Sharp,stat. n., of the parasitoid rove-beetle genus Aleochara Gravenhorst (Coleoptera,Staphylinidae, Aleocharinae) from Japan,Taiwan, and the Russian Far East

The subgenus Tinotus Sharp, 1833, stat. n., of the genus Aleochara Gravenhorst, 1802 (Aleocharini: Aleocharina) from Japan, Taiwan, and the Russian Far East is revised. Tinotus is a new record from the latter two regions. Three species are recognized: Aleochara (Tinotus) morion Gravenhorst, 1802, comb. n. [Japan (new record), the Russian Far East (new record)], Aleochara (Tinotus) eoa nom. n. [replacement name for Tinotus japonicus Cameron, 1933; Japan, Taiwan (new record)], and Aleochara (Tinotus) takashii sp. n. (central Honshû, Japan). The systematic position of Tinotus is discussed. All species are (re-)described, keyed, and figured. A world checklist of Tinotus species, comprising 40 valid species, is provided in an appendix. Additional taxonomic changes are proposed, including a new synonymy, a revalidation, 13 new replacement names, and 27 new combinations.     

A new Eastern Asian Hycleus and key to the Chinese species of the phaleratus group (Coleoptera,Meloidae, Mylabrini)

A new species of Hycleus belonging to the phaleratus group, and close to Hycleus phaleratus, is described. The new species, Hycleus marcipoli, is distributed in China (Gansu and Taiwan), Laos, and northern Thailand. A key to the Chinese species of this group is presented.     

New Early Jurassic brachiopods from the Western Tethys (Eastern Subbetic, Spain) and their systematic and paleobiogeographic affinities

Two new brachiopod genera (Alebusirhynchia and Praesphaeroidothyris), five new species (Alebusirhynchia jorali, Salgirella? goicoecheai, Praesphaeroidothyris cisnerosi, Lychnothyris lancisi, and Cincta peiroi) and a new combination (Securina plicata) have been recorded and established after the internal and external morphological study of populations attributed to Lower Jurassic carbonate successions of the South-Iberian Paleomargin (SE Spain). The analysis made enables us to detail the diagnostic characters of little-known genera such as Lychnothyris or Securina and to clarify the systematics of the group from new supraspecific definitions, establishing a new, strongly multicostate rhynchonellid genus (Alebusirhynchia) and a new smooth terebratulid genus (Praesphaeroidothyris). The palaeobiogeographic signature of these taxa has been analysed, revealing remarkable Mediterranean affinities. Thus, the previously restricted geographical distribution of these faunas can be extended to the westernmost Tethys areas, where the maximum degree of endemism is established for the brachiopod groups in the Subbetic domain around the Sinemurian-Pliensbachian transition.     

Two new species in the subfamily Perlinae (Plecoptera,Perlidae) from China

Two species in the genera Neoperla and Kamimuria (Plecoptera: Perlidae) from China are described as new: Kamimuria guangxia sp. n., and Neoperla mesostyla sp. n. The new species are compared to similar taxa.     

A synoptic review of the genus Thaumaspis Bolívar (Orthoptera,Tettigoniidae, Meconematinae) with the description of a new genus and four new species

Two new species of the new genus Athaumaspis gen. n., Athaumaspis minutus sp. n. and Athaumaspis tibetanus sp. n. from Vietnam and China are described. The subgenus Pseudothaumaspis of Thaumaspis is elevated to generic status and another two new species Pseudothaumaspis bispinosus sp. n. and Pseudothaumaspis furcocercus sp. n. are described, the remaining species of Thaumaspis are reviewed and keyed with the four new species.     

A new species of Noblella (Amphibia,Anura, Craugastoridae) from the humid montane forests of Cusco,Peru

A new species of Noblella is described from the humid montane forest of the Región Cusco in Peru. Specimens were collected at 2330–2370 m elevation in Madre Selva, near Santa Ana, in the province of La Convención. The new species is readily distinguished from all other species of Noblella by having a broad, irregularly shaped, white mark on black background on chest and belly. The new species further differs from known Peruvian species of Noblella by the combination of the following characters: tympanic membrane absent, small tubercles on the upper eyelid and on dorsum, tarsal tubercles or folds absent, tips of digits not expanded, no circumferential grooves on digits, dark brown facial mask and lateral band extending from the tip of the snout to the inguinal region. The new species has a snout-to-vent length of 15.6 mm in one adult male and 17.6 mm in one adult female. Like other recently described species in the genus, this new Noblella inhabits high-elevation forests in the Andes and likely has a restricted geographic distribution.     

A new species of blunt-headed vine snake (Colubridae, Imantodes) from the Chocó region of Ecuador

We describe a new species of Imantodes from the Chocó region of northwestern Ecuador. The new species differs most significantly from all other congeners in lacking a loreal scale. We analyze the phylogenetic relationships among species of Imantodes based on two mitochondrial genes, and postulate that the new species and Imantodes lentiferus are sister taxa. A key to the species of Imantodes from Ecuador is presented.     

Dinoflagellate cysts,Acritarchs and Tasmanitids from the uppermost Callovian of England and Scotland: With a reconsideration of the “xanthidium pilosum” problem

Four assemblages of fossil organic-walled microphytoplankton from the Upper Callovian (Lamberti Zone), three from England and one from Scotland, are described. They comprise at least 50 species of dinoflagellate cysts, 18 species of acritarchs and 2 species of tasmanitids. After a review of the «Xanthidium pilosum problem, a revised diagnosis is proposed for Sentusidinium pilosum (Ehrenberg) and three new species, Sentusidinium creberbarbatum, S. sparsibarbatum and S. erythrocomum are proposed. The new family name Scriniodiniaceae is substituted for the now invalid family name Endoscriniaceae. The new genus Escharisphaeridia is proposed to contain two existing species, E. pococki (Sarjeant) and E. dictydia (Sarjeant). The present content of the genus Compositosphaeridium is examined; the new combination C. polonicum (Górka) is proposed and a new species, C. bulgaricum, is erected. One further new species of dinoflagellate cyst, Prolixosphaeridium anasillum, is proposed. The new term «peniplate is proposed for paraplates whose boundaries are penitabular in situation.One new species of acritarch, Solisphaeridium?rhachos, is described and the new combination Polygonium aster (Sarjeant) is proposed. Evidence for reworking of some of the species of Micrhystridium present in the Hackness Rock assemblage is noted, though it is considered that the majority of species in that assemblage are indigenous. It is considered that all four assemblages are derived from a single phytoplankton province, the differences between them resulting from environmental factors such as water depth or distance from a shoreline.
