Aeolid opisthobranch molluscs (Glaucidae) from the Indian Ocean and the south-west Pacific

Eight aeolid opisthobranch molluscs of the subfamilies Facelininae, Favorininae, and Herviellinae are reported from Tanzanian waters, and two species from Northwestern India. New records from Queensland, Australia greatly extend the range of two species reported from Tanzania. Phidiana militaris (Alder & Hancock) and P. indica (Bergh) are shown to be distinct and a species from New Zealand, originally identified as P. militaris , is shown to be new. P. bourailli (Risbec), previously reported only from New Caledonia, is described from Tanzania, as is a new species of Phidiana. Favorinus japonicus Baba is reported from Tanzania, the first published record outside Japan, a new species of Godiva is described from Tanzania and Queensland, and three new species of Sakuraeolis are described, one from India and two from Tanzania. A new species of Herviella is described from Tanzania.     

New taxa of Hawaiian corticioid fungi are described with keys to Crustoderma, Radulomyces, and Scopuloides

Four new species of corticioid fungi from Hawaii are described and illustrated. The new genus Hemmesomyces is described to accommodate the new species H. puauluensis. Radulomyces tantalusensis, Crustoderma fuscatum and Scopuloides magnacystidiata also are described as new. In addition, the new combination Crustoderma vulcanense is proposed. Keys to the species of Crustoderma, Radulomyces and Scopuloides are provided.     

Pronophiline butterflies (Satyridae) of the Cordillera de Mérida, Venezuela

The 36 species of the tribe Pronophilini known from the Cordillera de Merida, the main Andean mountain range in Venezuela, are listed, together with three others probably erroneously described or labelled as from the range. The general ecological characteristics of the tribe are described, using the Merida species as examples. These include its restriction to high altitudes, endemism in mountain 'islands', species partitioning up the altitude gradient, mimicry within the tribe, and seasonality. The evolutionary relationships of the 16 endemic species are analyzed. Two new genera, six new species, two new subspecies and one new form are described. Three new synonymies are established, three new combinations made, new status is given to two taxa and the status of one taxon is revised.     

A new species of Acanthostigma (Tubeufiaceae, Dothideomycetes) from the southern hemisphere

A new species belonging to the Dothideomycete genus Acanthostigma is described from bark of two Nothofagus species from Argentina. Its identity as a new species is based on both morphology and molecular sequence data. Acanthostigma patagonica differs from other species in the genus by having larger ascomata and setae and wider, asymmetrical ascospores. An amended key to Acanthostigma species is provided along with a discussion of other species previously described from South America.     

Some American Austrolimnius (Coleoptera: Elmidae)

A key is given to the North American species of Austrolimnius, one of which is described as new. A new species from Venezuela is described, and new locality records in North and South America are listed for previously described species.     

A new species of Penicillium from the Chilean Tierra del Fuego

A new species of Penicillium is described and illustrated. It is represented by two isolates recovered from sandy soils on the shores of Lake Sarmiento, in the Chilean Tierra del Fuego. The new species clearly differs from all species of the genus described so far among the monoverticillate ones, especially by the unique wall ornamentation pattern as viewed with the SEM. It is therefore, described and proposed as a new taxon: Penicillium lacussarmientei sp. nov.     

Deep-sea asellote isopods of the north-east Atlantic: the family Dendrotionidae and some new ectoparasitic copepods

A new species of Dendromunna and two new species of Dendrotion are described from abundant material collected in the Rockall Trough region of the north-east Atlantic. The taxonomy of the little known benthic deep-sea asellote isopod family Dendrotionidae is reviewed and keys provided for genera and species. Also diagnosed and described are two new species belonging to a new genus of siphonostomatoid copepod found as ectoparasites on the walking legs of the new Dendromunna. The new parasites belong in the Rhizorhina group of genera within the family Nicothoidae.

CARRETERO, J. L., 1992. A new species of Anthemis L. (Asteraceae) from Central Spain. A new species of Anthemis is described from the eastern Toledo Mountains. The morphological relationships to other taxa, as well as the chorology and ecology of the new species are presented.     

A new species of Oxelytrum Gistel (Coleoptera, Silphidae) from southern Argentina, with a key to the species of the genus

A new species of the forensically interesting genus Oxelytrum Gistel (Coleoptera, Silphidae), Oxelytrum selknan, is described from Santa Cruz and Tierra del Fuego provinces, Argentina. The new species resembles Oxelytrum biguttatum (Philippi) in outer aspect, but has different male genitalia, in particular a median lobe longer than the paramera. All the described species of Oxelytrum have the median lobe shorter than the paramera. The internal sac, as far as it could be reconstructed from dry-pinned specimens, also shows differences between the two species. A key to the species of Oxelytrum is given and illustrated.

New genera, species, and improved phylogeny of Glissomonadida (Cercozoa)

Glissomonadida is an important cercozoan order of predominantly biflagellate gliding bacterivores found largely in soil and freshwater. Their vast diversity is largely undescribed. We studied 23 mostly newly isolated strains by light microscopy and sequenced their 18S rDNA genes; nine represent new species. For two misidentified ATCC 'Heteromita triangularis' strains, we establish novel gliding genera and species: the sandonid Mollimonas lacrima, the only glissomonad forming anterior and posterior pseudopodia, and Dujardina stenomorpha, a strongly flattened member of the new family Dujardinidae. A new strain from Oxfordshire grassland soil is the first reliably identified isolate of the virtually uniflagellate, smooth-gliding glissomonad genus, AllantionSandon, 1924. Phylogenetic analysis and cytological features reveal Allantion to be a member of Allapsidae. Sandona limna and Bodomorpha prolixa from Lake Baikal and Sandona hexamutans from volcanic Costa Rican soil are described as new species. Fifteen glissomonad strains were from grassland beside Lake Baikal. We describe two as new species of Sandona (S. heptamutans and S. octamutans); the others included strains of Sandona and Allapsa species that have already been described; and three were new species of Sandona and Allapsa but these died before being described. We discuss the ecological and evolutionary significance of these new strains.

Species of the genus Crotonia (Acari: Cryptostigmata) from New Zealand

Five new species of Crotonia from New Zealand ( C. cervicorna, C. cupulata, C. longibulbula, C. tuberculata and C. reticulata ) are described as new, and two species ( C. cophinana (Michael 1908) and C. caudatis (Hammer 1966)) are redescribed. Five species groups of the genus are characterized and a key to the adequately described species of the world is presented.     

A new Chorizococcus species (Coccoidea, Pseudococcidae) from Taiwan with transferring of Chorizococcus mirzayansi Moghaddam to genus Spilococcus Ferris

A new mealybug species, Chorizococcus zoysiaesp. n., feeding on Zoysia tenuifolia (Poaceae), is described from Taiwan. Adult female, third-instar female, second-instar female and first-instar nymph were described and illustrated in this article. Keys are provides to (a) separate this new species from similar species of Chorizococcus and those of same genus on zoysia grasses and (b) to identify instars of the new species. In addition, Chorizococcus mirzayansi Moghaddam is transferred to the genus Spilococcus as Spilococcus mirzayansi (Moghaddam), comb. n.     

Genus Autosticha Meyrick (Lepidoptera: Autostichidae) from Taiwan,China

Fourteen species of the genus Autosticha Meyrick,1886 are recorded from Taiwan,China.The genus Cynicocrates Meyrick,1935 is proposed as a new synonym of Autosticha,and its type species A.tachytoma (Meyrick,1935) comb.nov.is transferred to Autosticha.Autosticha cordiformis sp.nov.is described as new,and A.tachytoma is redescribed with male for the first time.A checklist of all the described species in Taiwan is given.Photographs of the new species and the newly combined species are provided.     

A new species of Sprostoniella Bychowsky and Nagibina, 1967 (Monogenea: Capsalidae) from Chaetodipterus zonatus (Osteichthyes: Ephippidae) in Chamela Bay, Mexico

A new species of Sprostoniella is described from the gills of Chaetodipterus zonatus in Chamela Bay, on the west coast of Mexico. The new species differs from the 2 previously described congeners by having smaller testes each of which is not nearly as long as the ovary. It further differs from the type species, Sprostoniella multitestis, by having a poorly developed pair of accessory sclerites and the cecal diverticula are not confluent posteriorly. The new species also differs from Sprostoniella micrancyra, the other species of the genus, by having a shorter peduncle, the glands of Goto are smaller than the testes and ovary, and by having a slightly different haptoral structure, with 1 pair of hamuli rather than 2 pairs, and 1 central haptoral loculus instead of 2 loculi.     

Narcinecotyle longifilamentus n. gen., n. sp. (Monogenea: Hexabothriidae), gill parasite of the numbfish Narcine entemedor (Torpediniformes: Narcinidae) from the Mexican Pacific coast

A new genus and species of Hexabothriidae Price, 1942 is described from specimens infecting the gill of the numbfish Narcine entemedor Jordan and Starks from the Pacific coast of Mexico. In addition to the new taxon described here, species of 8 genera also display symmetrical haptors and have eggs with two polar filaments. However, they differ in the combination of the following features: distal portion of the male copulatory organ tubular, unarmed and proximally dilated confining an internal coiled duct, as well as dorsal origin of haptoral appendix. Based on molecular data derived from 3 loci, the mitochondrial Cytochrome C oxidase subunit 1 as well as the nuclear ribosomal 18S and 28S, the new species was found nested within Hexabothriidae together with the other 4 genera with representatives in GenBank. This is the first species of Hexabothriidae reported from a species of Narcinidae.
