Sexual Form

A survey of lignicolous terrestrial ascomycetes conducted in Thailand yielded a number of novel species. In this paper, we report on a terrestrial collection of a taxon from dead branches of an unidentified plant. Triseptata gen. et sp. nov. is characterized by immersed, uni- to multi-loculate ascomata, filamentous pseudoparaphyses, bitunicate, fissitunicate, cylindrical-clavate asci and 3-septate, light brown spores, with asymmetrical ends, in its sexual form. In culture, it produced hyphomycetous, globose to subglobose, multi-septate and darkly pigmented conidia-like structures. Phylogenetic analysis of a combined LSU, ITS and SSU dataset shows Triseptata to be a well-separated lineage from all genera in Latoruaceae. Based on multigene phylogeny, Triseptata gen. nov. is introduced to accommodate a single new species Triseptata sexualis and placed in Latoruaceae. Illustrations, descriptions and notes are provided for the new genus and species.

A collection of 17 isolated rodent molars from a cave in the eastern part of Duivelsklip, Curaçao, Dutch West Indies, isdescribed as Dushimys larsi, new genus and species. The new species is characterized by relatively large size, broad mo-lars, absence of mesolophid and presence of anterolophid and anterolabial cingulum on m3, absence of metaloph on M3,and m2 with three roots. Phylogenetic analysis could not conclusively resolve the position of the new species, and it isprovisionally regarded as a representative of an otherwise unknown oryzomyine genus. The material is likely middle Pleistocene in age.

A New Species

Corotoca is a strictly Neotropical genus of termitophilous beetles associated with termites of genus Constrictotermes. A cladistic analysis based on 13 terminal taxa and 60 characters (57 morphological and three behavioral) was conducted. The exhaustive search with equally weighted characters resulted in two most parsimonious trees with 95 steps. Spirachtha is proposed to be the sister group of the monophyletic “subgroup Corotocae” (Corotoca + Cavifonexus gen. nov.), based on eleven synapomorhphies (ten exclusive and one homoplastic). The monophyly of Corotoca is supported here, including six species associated with Constrictotermes cyphergaster: (Corotoca hitchensi sp. nov + (C. melantho + C. pseudomelantho sp. nov.) + ((C. fontesi + (C. phylo + C. araujoi)). A new genus, Cavifronexus gen. nov., is proposed to two species associated with Constrictotermes cavifrons (Holmgren, 1910): Cavifronexus guyanae comb. nov., from Guyana and Brazil, previously described as Corotoca; and a new species, Cavifronexus papaveroi sp. nov., from Brazil. This work also includes descriptions, redescriptions, and illustrations for all species and genera. Keys for genera and species identification in “subgroup Corotocae” are also provided.

The Family

A morphological phylogenetic analysis is conducted of Australasian harvestmen previously included in the family Monoscutidae. Monophyly of Monoscutidae is not supported, and the subfamilies Monoscutinae and Megalopsalidinae are synonymised with the South American subfamily Enantiobuninae. Monoscutidae is re-synonymised with the family Neopilionidae. The analysis also demonstrates the polyphyly of species previously assigned to the genus Megalopsalis. Megalopsalis epizephyros new species, M. eremiotis new species, M. leptekes new species and M. pilliga new species are described and M. serritarsus and M. hoggi are redescribed, all from Australia. Hypomegalopsalis tanisphyros new genus and species is described from Western Australia. Megalopsalis linnaei is transferred to Tercentenarium new genus. Forsteropsalis new genus is established to include species from New Zealand (including Auckland Island): Macropsalis chiltoni (type species), Pantopsalis distincta, Macropsalis fabulosa, Pantopsalis grayi, Megalopsalis grimmetti, Megalopsalis inconstans, Megalopsalis marplesi, Megalopsalis nigra and Pantopsalis wattsi.

Argentine Precordillera

The following new Toernquistiidae from Whiterockian (Llanvirn to lower Caradoc) strata of the Precordillera, western Argentina, are described: Chomatopyge canasi new species, Lasarchopyge benedettoi new genus and species, Lasarchopyge correae new genus and species, Lasarchopyge new species A, and Paratoernquistia sanchezae new genus and species. Phylogenetic analysis suggests that the Toernquistiidae Hupé, 1953 (including Chomatopyge, Lasarchopyge, Mesotaphraspis, Paratoernquistia, and Toernquistia) is closely related to but distinct from the Dimeropygidae Hupé, 1953 (including Ischyrotoma, Ischyrophyma and Dimeropyge). It is difficult to find unique synapomorphies that unite toernquistiids and dimeropygids into a monophyletic group that excludes other proetides (e.g., hystricurids), although details of their ontogenies are similar. Several species of Toernquistiidae are known from the Argentine Precordillera (one species previously described), and other species of this family have been described from Australia, Baltica, China, Kazakhstan and Laurentia. Members of the Dimeropygidae are known only from Baltica and Laurentia.

We describe Melanosternarchus amaru as a new genus and species of Apteronotidae from the deep channels of blackwater and clearwater tributaries of the Amazon River in Brazil and Peru. The new species superficially resembles members of the widespread “Apteronotus” bonapartii species group, from which it can be readily distinguished by expanded bones of the infraorbital laterosensory canal. It can further be distinguished from all other apteronotids by a unique combination of characters: reduced premaxillary dentition, a large gape, and an absence of scales from the entire dorsum. A molecular phylogenetic analysis using three mitochondrial loci and one nuclear locus (~3000 bp) places this genus as sister to Compsaraia, and these two genera together as a clade sister to Pariosternarchus; all nodes with strong statistical support. The clade formed by these three genera includes five species, four of which are restricted to the Amazon basin. The apparent habitat preference of the new species for low-conductivity blackwater and clearwater rivers has not been reported in other apteronotid species.

Twelve brachiopod taxa are described from the Early Devonian (probable early Emsian) Pa Samed Formation of southern Thailand, including the new genus and species Quasiprosserella samedensis (Ambocoeliidae?) and the new species Plectodonta forteyi, Caplinoplia thailandensis, and Clorinda wongwanichi. They are the first undoubted Devonian brachiopods from Thailand. They represent the deeper-water Benthic Assemblages BA4-5, and, although clearly indicative of the Old World Realm, cannot be assigned to a particular biogeographical region. A new undescribed fauna from the contemporary Zebingyi Formation of Burma (Myanmar) is also noted.

Basal Structure

Abstract. A very distinctive new deep-photic coccolithophore is described from the NE Indian Ocean. The new species is trimorphic with: 200–300 body coccoliths bearing low spines attached by narrow stems to a basal narrow-rimmed placolith structure; up to 18 circum-flagellar coccoliths with tall sail-like spines; and up to 22 coccoliths with moderately elevated spines occurring both around the circum-flagellar coccoliths and antapically. These features make the coccolithophore unique and require placement in a new species and genus. The basal structure, however, shows similarities to a recently recognized group of narrow-rimmed placoliths. Hence, the new coccolithophore provides some support for this grouping as a significant addition to our understanding of coccolithophore biodiversity, and potentially an explanation for a set of anomalous molecular genetic results. In addition the new taxon provides further evidence that the deep-photic coccolithophore community is more diverse than has been assumed.

AbstractThe 11 genera of Nearctic Braconini are keyed: two of them, Myosoma Brullé with a wide pantropical range and Alienoclypeus Shenefelt, new genus, are found chiefly in the Chihuahuan desert and shrub fauna of northern Mexico and the southwestern U.S.A. and are recorded as Nearctic for the first time. Four new species are described in Myosoma: eumystax, impexum, longius, and durango. R. D. Shenefelt describes a new genus and species, Alienoclypeus insolitus. The genus Atanycolimorpha Viereck, 1913 is synonymized with Ipobracon Thomson, 1892. The genus Coeloides is revised for the Nearctic Region; 12 species are described and illustrated. Five of these are new: mexicanus, durangensis, sympitys, tsugatorus, and sonora. One species, C. rossicus (Kokujev), is Holarctic, a new subspecies, betulae, is described from Canada. The following are new synonyms: C. rufovariegatus (Provancher) = (dendroctoni Cushman), C. vancouverensis (Dalla Torre) = (brunneri Viereck), C. crocator (Kirby) = (promontorii Dalla Torre).
