Marielliottia, a new genus of hyphomycetes, is described. Three species formerly treated in Drechslera are included: D. biseptata, the type, D. dematioidea, and D. triseptata. The species differ from Drechslera in having mostly three-septate, obovoid to ovoid conidia that germinate primarily from the basal cell, occasionally from the apical cell, and not from the central cells. These fungi are occasional parasites of cereals and grasses, are sometimes seed borne, and may infect nongrass plants. The type species is implicated in mycotoxicosis of sheep and produces zaragozoic acid A.Key words: mycotoxins, Helminthosporium, M. biseptata, M. dematioidea, M. triseptata.

Distinct Features

Ramakrishnania is described as a new genus of rust fungi with R. ixorae n.sp as the type species. Distinct features of this genus are the indeterminate growth of the basal cell and the formation of two-celled puccinioid teliospores on septate simple pedicels bilaterally on the elongating basal cell.

Three New Species

A new genus and three new species of Hemiptera: Heteroptera: Enicocephalomorpha: Enicocephalidae: Enicocephalinae are described from Malaysia: Sabah, viz. Phaenicocleus n. gen. sabahensis n. sp. (type species), P. schwendingeri n. sp. and P. minor n. sp. (all species male-based). The new genus is macropterous and belongs to that group of Enicocephalinae characterized by presence of large, closed discal cell and absence of basal cell in forewing. The species are distinct in the character states of the median of pronotum, shape of unpaired sclerite of the pro-eusternum, and shape and length of a median keel of meta-eusternum – these are characters previously unemployed as diagnostic in the Enicocephalidae.

Teratospermopsis is proposed as a new genus for Chaetendophragmia protuberata [= Teratosperma microsporum]. The genus has acrogenous, solitary, euseptate conidia seceding schizolytically from monoblastic, integrated, terminal, annellidic conidiogenous cells. The conidia are obclavate, smooth, and with an apical cell with a filiform appendage and a basal cell with a lateral appendage. A key and a synoptic table to six accepted Teratosperma species accompany comments on four rejected or dubious species, including T. macrosporum [= Endophragmiella macrospora comb. nov.].

A new genus of Gyponini, Sakakibarana gen. nov., is proposed and its type species S. amazonica sp. nov. is described and illustrated based on specimens from the Amazon Rainforest of Northern Brazil (states of Amazonas and Pará) and French Guiana. The new genus can be distinguished from other members of the Gyponini by the following morphological features: robust body, short crown, crown and face transition distinct and subfoliaceous, pronotum strongly declivous, male pygofer with caudal process, and aedeagus with dorsal apodemes with a pair of processes. A discussion comparing the new genus with the related genus Tenuacia DeLong, 1977 is provided.

A new genus and five new species of odiniids (Odiniidae: Traginopinae) are described from the Brazilian Amazon and Cerrado biomes: Inpauema mirador gen. nov. et sp. nov. (type species), I. catarinae sp. nov., I. gaimarii sp. nov., I. raimundoluizi sp. nov., and I. xavieri sp. nov. The genus is being characterized by a unique combination of diagnostic characters: body predominantly dark brown to black, with silvery-gray pruinose spots on inner margin of eyes, longitudinally along middle of lunule and face, on notopleuron and mesopleuron; postcranium concave from dorsal view; one pair of stout proclinate ocellar setae; postocellar setae absent; lunule shorter than frons; gena lacking upturned seta; antennae separated by a maximum distance of 2X the diameter of a single antennal socket and gonocoxal apodemes directed upward, forming an arch. A key to separate Helgreelia Gaimari, 2007 from Inpauema gen. nov. and for the new species is provided.

Bromodesmus catrionae n. gen., n. sp. (type species), B. militaris n. sp., B. riparius n. sp. and B. rufus n. sp. are described. The new genus is characterized by greatly reduced paranota and a gonopod telopodite expanded at the distal end into a posteriorly concave hood fringed with teeth; the hood partly protects a long, curved, acutely pointed solenomerite. Male leg setation in the type species of six Tasmanian dalodesmid genera is briefly discussed and illustrated with scanning electron micrographs. The sphaerotrichome shaft is sharply pointed in Atrophotergum; gently tapered in Dasystigma, Lissodesmus and Tasmanodesmus; expanded at the tip in Bromodesmus; and entirely absent in Gasterogramma. Tips of the setae forming the dense ventral brush on male podomeres are gently tapered in Dasystigma and Lissodesmus, truncated in Gasterogramma, expanded in Bromodesmus and forked in Tasmanodesmus.

The Family

Concepts of the family Hyolithidae Nicholson fide Fisher and the genera Hyolithes Eichwald and Orthotheca Novak have been expanded through time to encompass a variety of morphologically dissimilar shells. The Hyolithidae is here considered to include only those hyolithid species which have a rounded (convex) dorsum; slopes on the dorsum are inflated, and the venter may be flat or slightly inflated. Hyolithes encompasses species which possess a low dorsum and a prominent longitudinal sulcus along each edge of the dorsum; the ligula is short and the apertural rim is flared. The emended concept of Orthotheca includes only those species of orthothecid hyoliths which have a subtriangular transverse outline and longitudinal lirae covering the shell on both dorsum and venter.Eighteen species of Hyolithes and one species of Orthotheca from the Appalachian region and Western Interior were reexamined in light of more modern taxonomic concepts and standards of quality for type material. Reexamination of type specimens of H. similis Walcott from the Lower Cambrian of Newfoundland, H. whitei Resser from the Lower Cambrian of Nevada, H. billingsi Walcott from the Lower Cambrian of Nevada, H. gallatinensis Resser from the Upper Cambrian of Wyoming, and H. partitus Resser from the Middle Cambrian of Alabama indicates that none of these species represents Hyolithes. Hyolithes similis is here included under the new genus Similotheca, in the new family Similothecidae. Hyolithes whitei is designated as the type species of the new genus Nevadotheca, to which H. billingsi may also belong. Hyolithes gallatinensis is referred to Burithes Missarzhevsky with question, and H. partitus may represent Joachimilites Marek. The type or types of H. attenuatus Walcott, H. cecrops Walcott, H. comptus Howell, H. cowanensis Resser, H. curticei Resser, H. idahoensis Resser, H. prolixus Resser, H. resseri Howell, H. shaleri Walcott, H. terranovicus Walcott, and H. wanneri Resser and Howell lack shells and/or other taxonomically important features such as a complete aperture, rendering the diagnoses of these species incomplete. Their names should only be used for the type specimens until better preserved topotypes become available for study. Morphology of the types of H.? corrugatus Walcott and “Orthotheca” sola Resser does not support placement in the Hyolitha; the affinities of these species are uncertain.

Generic Status

In my work on the Chilean Mesostenini it early became evident that the Cryptus cyanipennis of Brullé, one of the most striking and easily recognizable of the described mesostenines of temperate South America, is sufficiently distinct from other known forms to deserve separate generic status. I therefore give below a description of this new genus together with a brief discussion of its affinities and a redescription of the type species.

Geological Formation

A new genus, Tikuna, is described based on recent collections of adults and nymphs of Choroterpes atramentum Traver from western Costa Rica. All recent collections are from streams on or near the Nicoya Complex, the oldest geological formation in Lower Central America. Tikuna belongs to a lineage of South American Atalophlebiinae (Leptophlebiidae: Ephemeroptera) whose origin is hypothesized to have been in the late Cretaceous–early Tertiary. Some implications of the distribution of Tikuna for theories on the origin of Costa Rica’s biota are discussed.
