New Genus And Species

Several polyplacophoran plates are preserved as external molds in the Lower Permian Rio Genoa Formation, Chubut Province, Argentina. These are the first reported Permian polyplacophorans from South America. The new genus and species Asketochiton chubutensis is described based on this material.

Redescriptions of Adelogyrinus simnorhynchus and Dolichopareias disjectus are given. The skulls of these forms are characterized by the very anteriorly placed small orbits and long post-orbital skull table. Further diagnostic characters are the exclusion of the ‘post-orbital’ from the orbit, the long straight suture between the squamosal and parietal and the absence of anotic notch. A parasternal process is present on the interclavicle. A new genus and species Palaeomolgophus scoticus of early Carboniferous age is described. It is an aquatic form with branchial arches, yet the characters it displays are essentially reptiliomorph, quite unlike those of the labyrinthodonts and resembling more those of lower Permian reptiles. It has microsaur-type vertebrae in which the centrum is a pleurocentrum, winged ribs, a differentiated series of cervical ribs and an interclavicle with a posterior parasternal process. The limbs are small, but well developed, with ossified condylar surfaces. Comparisons are made with Microbrachis from the Upper Carboniferous of Nyran, the type microsaur, which is represented mainly by larval forms, but the disappearance of the lateral line canals in larger skulls indicates a metamorphosis. Microbrachis is more primitive than Palaeomolgophis in that small pre-sacral as well as post-sacral intercentra are present. Evidence is given which leaves little doubt that in microsaurs generally the vertebrae are of apsidospondylus type and the centrum is a pleurocentrum. They are not lepospondylous and the validity and usefulness of the term ‘Lepospondyli’ is questioned. The evidence presented here supports the view that there was a deep and early split in tetrapods separating the labyrinthodonts (batrachomorphs) from the reptiliomorph types, (the Lower Carboniferous microsaurs, microbrachids, gymnarthrids, seymouriomorphs, etc.). All display more or less a series of structures never found in any labyrinthodont and which indicate either a very early divergence from the labyrinthodont stock or a separate origin from fishes. The emergence of essentially reptilian characters in Palaeomolgophis , an apparently aquatic form of Lower Carboniferous age contradicts the assumption that these characters arose as adaptations to land life and indicates that the first move toward the reptilian condition was structural and that it was only at a later date that the life-history was modified and that terrestrial tetrapods, reptiles in the full sense, arose.

In the paper six new species of the genus Oisenodes gen. nov. (Dermestidae, Trinodinae, Trinodini) are described: O. azari sp. nov., O. clavatus sp. nov., O. gallicus sp. nov., O. metepisternalis sp. nov., O. oisensis sp. nov. and O. transversus sp. nov. A new tribe Trinoparvini Hava, trib. nov. is established for the recent genus Trinoparvus Háva, 2004. Short review of known fossil records of the subfamily Trinodinae is given.

A new genus and species, Unguitarsonemus paradoxus n. gen., n. sp. and a new species, Pseudotarsonemoides peruviensis n. sp. (Acari: Trombidiformes: Tarsonemidae), are described based on phoretic females collected on bark beetles Phloeotribus pilula and Ph. biguttatus, respectively, from Peru. A key to species of the genus Pseudotarsonemoides is provided.

Abstract A new genus and species of carneyellid edrioasteroid, Spiracarneyella florencei n. gen. n. sp., is described from the Upper Ordovician (Kaitian) Point Pleasant Formation of northern Kentucky and southern Ohio. Spiracarneyella n. gen. is characterized by having all five ambulacra curving clockwise around the theca, having small node-bearing interambulacral plates in the distal interambulacra, and having the periproct placement slightly offset to the right side of the CD interambulacrum. The oral area of carneyellids evolved by paedomorphosis of the oral plates covering the mouth. The straight ambulacra of Cryptogoleus and the spiraling ambulacra of Spiracarneyella n. gen. evolved by paedomorphosis and peramorphosis, respectively.
