Synopsis of the Japanese species of Aleocharinae (Coleoptera: Staphylinidae), with review of the type specimens II. Genus Myllaena Erichson of tribe Myllaenini,with redescription of four Japanese species

Four Japanese species the rove beetle genus Myllaena are redescribed based on the type material. They are: M. japonica Sharp, 1888, M. lewisi Cameron, 1933, M. rufotestacea Cameron, 1933, and M. torrentum Cameron, 1933. Myllaena chinoculata Pace, 1998 described from China is synonymized with M. lewisi. All of these species are illustrated and mapped.

Nomenclator, geographic and stratigraphic distribution of the family Triphoridae (Mollusca: Gastropoda)

The microgastropod family Triphoridae is one of the five most diverse marine molluscan families. It likely hosts a few thousand species worldwide, but its taxonomy has long been considered challenging due to the high diversity and subtle morphological characters needed for species delimitation. Consequently, only a small portion of the species appears to be formally described to date. However, further taxonomic work should be based on robust knowledge on the numerous names introduced so far. In this perspective, we have here compiled a list of all published names that can be attributed to the fossil and extant Triphoridae. We list 958 species and 75 genus names, of which 771 are known as extant species and 146 as fossil species, 41 are known from both fossil and extant records. We provide information on type locality and horizon, type material, synonymy and homonymy. Importantly, based on the review of hundreds of publications, we provide a preliminary overview of the geographic and stratigraphic distribution.

Identity of Carex trichodes Steud. ex Boott and Carex lateriflora Phil. (subgen. Psyllophorae, sect. Junciformes, Cyperaceae) from Southern South America

The identity of Carex trichodes, a species only known from the collection of the type material made in 1854 is clarified after finding it in the wild in the vicinity of the type locality. It is concluded that C. trichodes was proposed based on stressed plants corresponding to the same taxon later described as C. lateriflora.

Typification of the genus Zizyphoides Seward et Conway (Magnoliophyta, Trochodendraceae)

Type material of Paliurus colombii Heer, Populus arctica Heer, Hakea arctica Heer, and Hedera macclurii Heer from the Atanikerdluk locality (Paleocene, Greenland) was restudied based on the original collection, stored in the National Museum of Ireland, Dublin. All these species were joined under the name Zizyphoides colombii (Heer) Seward et Conway, type species of the genus Zizyphoides Seward et Conway. A lectotype of Zizyphoides colombii is designated and the diagnosis of this species is emended. An emended diagnosis of the genus Zizyphoides is also presented.

A new species of Ampithoe (Amphipoda, Ampithoidae) from Korea, with a redescription of A. tarasovi

An ampithoid species, previously known as A. tarasovi in Korea, is assigned as a new species, A. changbaensissp. nov. based on the reexamination of the holotype of A. tarasovi. The new species shows different morphological characteristics compared to A. tarasovi, especially in male gnathopods 1 and 2. The type material of A. tarasovi is redescribed and illustrated here and a key to the Korean species of Ampithoe is provided.

Jurodidae (Coleoptera: Archostemata) from Transbaikalia: new findings and redescription of type material

Two species of Jurodidae: Jurodes ignoramus and Jurodes minor are redescribed, new characters presented, and characters from original descriptions are phylogenetically reevaluated, justifying a placement of the family within the suborder Archostemata. The new species Jurodes shef sp. nov. from the Lower Cretaceous locality Khasurty (Berriasian-Barremian, Zakamenskiy district, Buryatia Republic, Russia) is described and 2 new specimens of J. ignoramus Ponomarenko, 1985 and 5 additional specimens of J. minor Ponomarenko, 1990 are recorded. Jurodids from Khasurty are morphologically closer to those from Daohugou locality (Middle–Upper Jurassic, Inner Mongolia, China).

Review of the hyperiidean amphipod family Lycaeidae Claus, 1879 (Crustacea: Amphipoda: Hyperiidea)

This is the first comprehensive taxonomic review of the family Lycaeidae. This study is based primarily on the extensive collections of the Natural History Museum, Denmark (NHMD, formerly ZMUC) and the US National Museum of Natural History, Smithsonian Institution, Washington DC, USA (USNM), and on additional material from the South African Museum (SAM) and in the South Australian Museum (SAMA). The two currently recognized genera in the family, Lycaea Dana, 1852 and Simorhynchotus Stebbing, 1888, are maintained with the latter still regarded monotypic with S. antennarius (Claus, 1871). Characters used to distinguish species in the past are re-evaluated in order to determine their validity. There are 15 nominal species of Lycaea in the literature, excluding Pseudolycaea pachypoda Claus, 1879 and Metalycaea globosa Stephensen, 1925. Pseudolycaea Claus, 1879 is regarded a synonym of Lycaea, as confirmed by this study, and M. globosa is a junior synonym of L. serrata Claus, 1879, as demonstrated by an examination of the type material. Of the remaining nominal species many have been synonymized with L. pulex Marion, 1874 in the past, often based on erroneous literature references. Thus, the taxonomic status of all nominal species was redetermined by the examination of type material or from the original literature reference if type material could not be found. In conclusion, ten species of Lycaea are recognized as valid, including three described as new. Lycaea bovallii Chevreux, 1900 is determined to be a valid species with the following as junior synonyms, L. gracilis Spandl, 1924, L. bajensis Shoemaker, 1925 and L. bovallioides Stephensen, 1925. It seems to be widely distributed and relatively common in the tropical regions of all the world’s oceans, including the Mediterranean Sea. The other species recognized as valid are L. lilia Volkov, 1982; L. nasuta Claus, 1879; L. pachypoda (Claus, 1879); L. pulex Marion, 1874 (L. robusta Claus, 1879, L. similis Claus, 1879 and L. pauli Stebbing, 1888 regarded junior synonyms); L. serrata Claus, 1879 and L. vincentii Stebbing, 1888 (Amphipronoe longicornuta Giles, 1888 a junior synonym). In addition, three species are described as new to science; L. intermedia sp. nov., L. proserrata sp. nov. and L. osbornae sp. nov. All were found in the tropical regions of the Atlantic, Pacific and Indian Oceans; the former two are relatively common and widespread. All species are described and illustrated and a key is provided to facilitate their identification.

Geastrum chamelense (Geastraceae, Agaricomycetes), a new species with setose endoperidium from the tropical dry forest in Jalisco, Mexico

Background and Aims: Geastrum is characterized by stelliform basidiomata, exoperidium with three layers, sessile or stalked endoperidium, and sulcate, plicate, folded or fibrillose peristome, distinctly or indistinctly delimited, sometimes with mycosclereids. The objective of this study is to describe and illustrate Geastrum chamelense with morphological, ecological and molecular data as a new species from the Chamela Biological Station, Jalisco, Mexico. Methods: Basidiomata collections with different degrees of maturity gathered in 2010 and 2011 from tropical dry forest at the Chamela Biological Station in Jalisco state are described macro- and microscopically. The type material is deposited in the fungal collections of the herbaria ENCB and MEXU. The extraction of DNA, as well as the phylogenetic analyses of ITS, LSU, atp6 and rpb1 sequences, are based on the holotype. Key results: Geastrum chamelense is distinguished by its greyish brown basidiomata, pseudofornicate, fleshy exoperidium, not hygroscopic, sessile endoperidium, subglobose to depressed with peristome plicate, not delimited, and setae present. The latter character is shared with Geastrum setiferum from Brazil, but that species has shorter and wider setae (95-215 × 20-47 µm) than G. chamelense (102-330 × 10.2-15.3 µm). From a phylogenetic perspective, G. chamelense is sister to G. hieronymi and G. cf. calceum, while G. setiferum is not related, as it appears in a separate clade. Conclusions: Geastrum chamelense is recognized as a new species based on morphological, ecological and molecular data.

Notes on Brazilian Pachira (Malvaceae, Bombacoideae) II: Additional typifications and new synonymies

The typification and status of the names of 14 species of Pachira (Malvaceae: Bombacoideae) found in Brazil are discussed, including type material from Brazil, the Guianas, Colombia, Venezuela, and cultivated in Algeria. We designate 11 lectotypes, three neotypes, and four epitypes for these names. Six names are newly considered to be synonyms of the species accepted here. The results support a forthcoming taxonomic treatment of Pachira for the Flora of Brazil.
