First Time

The Upper Devonian (Frasnian) conodont fauna of the Lime Creek Formation of north-central Iowa is dominated by species of Polygnathus. Patterns of species composition and abundance are consistent with the Polygnathus biofacies described from the Frasnian of the Northwest Territories of western Canada. Consequently, the standard Frasnian conodont zones, defined on sequences developed in the Palmatolepis biofacies, are not applicable to the Lime Creek sequence. The Lime Creek conodont sequence correlates with Zones 4, 5 and Faunal Interval 7 of the Frasnian conodont sequence in the Alberta Rockies and with similar sequences in the southwestern United States. The Pb elements of Palmatolepis semichatovae Ovnatanova and Ancyrognathus? deformis (Anderson) are described and illustrated for the first time.In the Lime Creek Formation of north-central Iowa, brachiopods of the lowermost part of the Nervostrophia thomasi Zone of Day (1989a) occur in Zone 4, brachiopods of most of the N. thomasi, Douvillina arcuata, and Cyrtospirifer whitneyi Zones span conodont Zone 5, and the Elita inconsueta and Iowatrypa owenensis Zones occur in Faunal Interval 7. Species of the ammonoid Manticoceras and of the gastropods Floyda, Turbonopsis, and Westerna are restricted to Faunal Interval 7. Species of the calcareous foraminifer Nanicella first occur in Zone 5, and are joined by species of Multiseptida high in Zone 5.

Eight new taxa of Eriophyidae mites associated with native trees in the Cupania genus—C. oblongifolia Mart. and C. impressinervia Acev (Sapindaceae)—from the Atlantic Forest in Brazil, are described and illustrated. They include two new genera and two new species of Nothopodinae, Colopodacini (Setibia domatiagena   gen. nov., sp. nov. and Aricolopodos alagoensis gen. nov., sp. nov.), one new genus and two new species of Cecidophyinae, Colomerini (Euryslobos keronidos gen. nov., sp. nov. and Gammaphytoptus cupanius sp. nov.), and one new species of Phyllocoptinae, Tegonotini (Shevtchenkella caboata sp. nov.).

New Genus And Species

In preparation for upcoming studies, several new taxa of Australian Erotylinae (Coleoptera: Erotylidae) need to be described to make names available. New genera and species in Dacnini and Megalodacnini are described. Echinothallis banderbearella, new genus and species (Dacnini); Microdacne, new genus, with four new species (Dacnini), M. gloriousa, M. lamingtonia, M. nardia, M. styxia; and Episcaphula (Tropidoscaphula) megalodacnoides, new species (Megalodacnini). Variation of female terminalia and other characters in several genera are discussed regarding the monophyly and generic diversity of Dacnini.

Abstract The fourth addendum to Schneider and Wynne’s 2007 “A synoptic review of the classification of red algal genera a half century after Kylin’s 1956 ‘Die Gattungen der Rhodophyceen’” is presented, covering the names of genus- and higher-level taxa added or modified since our third addendum (Bot. Mar. 59: 397–404). Since that synopsis, we added 21 new genera in a first addendum, 27 in the second, and 40 in the third, demonstrating the increasing amount of genetic work over more than a decade. In this fourth addendum, we add 58 new genera to the list of red algae as well as many new taxa in the hierarchical framework over the past 3 years. Based upon molecular sequencing, other genera reinstated from synonymy studies are included.

Two New Species

Since the phylogenetic analysis of the Herrichella clade (Ochlerini) new genera were described to fit monophyletic groups inferred and considered to be new taxa. The clade I supported by two synapomorphies of the female genitalia, grouped Alitocoris brunneus Sailer together to two new species. Alloeogyna gen. nov. is described here for this clade including the two new species Alloeogyna ampla sp. nov. and Alloeogyna poecila sp. nov. and a new combination is proposed for Alloeogyna brunnea comb. nov.. Also, Alitocoris maculosus Sailer recovered within the clade E in the Herrichella clade is here redescribed in the monotypic Sailerus gen. nov. resulting in the new combination Sailerus maculosus comb. nov..

Attempts at understanding evolutionary relationships among Paleozoic Dipnoi (lungfish) using cladistic methodology have proved totally unsatisfactory (Miles 1977; Marshall 1987). We attempt to reconstruct the relationships between the better known genera using a method that involves the recognition of lineages based on evolving functional complexes, particularly those involved with food reduction and respiration. Within these broadly defined lineages, we have defined sub-lineages based on evolutionary patterns shown by structures that have been stratigraphically dated; such patterns are found inter alia in the roofing bones and the external dermal bones of the mandible. A number of new suborders and families are recognised; genera for which further morphological data are required before they can be assigned to a higher taxon are indicated; two generic synonyms are recognised.In appendices, short descriptions are given of two new genera—Pillararhynchus from the Gogo Formation (Upper Devonian) of Western Australia, and Sorbitorhynchus from the Emsian of Guangxi, China.

Ocala Limestone

Oyenaster oblidus, Ocalaster timucum, and Ocalaster seloyi are new genera and species of the family Goniasteridae (Asteroidea) described from the Eocene Ocala Limestone of Florida. Although the fossil record of asteroids is sketchy, goniasterids appear to have been important contributors to marine communities since at least the Middle Jurassic. Similarities between living goniasterids and their fossil precursors indicate that plesiomorphy and convergence have been important in family history, and as a result, taxonomic interpretation is challenging. Even partial fossil goniasterids are rare, forcing systematists to rely heavily on isolated marginal ossicles, although some authors have expressed the need for caution. Building around three new taxa, we suggest that broader approaches can aid systematic interpretation of all crown-group asteroids. We also suggest that the inevitably idiosyncratic interpretations of marginal-based systematics can be partially tested using blind evaluations.
