A new classification is proposed for late Paleozoic Edrioasteroidea (Echinodermata), separating forms with the advanced clavate thecal design from those with the ancestral pyrgate thecal design, and a new Subfamily Discocystinae is erected to receive the clavate agelacrinitid edrioasteroids. Lepidodiscus Meek and Worthen is restricted to the pyrgate type species L. squamosus (Meek and Worthen) and two unnamed species, whereas the clavate L. laudoni (Bassler) is assigned to Clavidiscus, new genus. The clavate Discocystis priesti Strimple and three new species, Hypsiclavus kinsleyi, new genus and species, Hypsiclavus huntsvillensis, new genus and species, and Hypsiclavus guensburgi, new genus and species, are placed in Hypsiclavus, new genus. Bostryclavus, new genus, is erected to receive Echinodiscus sampsoni Miller. A redescription of Discocystis kaskaskiensis (Hall) and a diagnosis of Spiraclavus Sumrall are included for completeness.

Eospongilla morrisonensis n. gen. and sp., the oldest-described freshwater sponge (Demospongea: Spongillidae), is found in the Upper Jurassic (?Oxfordian/Kimmeridgian to Tithonian) Morrison Formation, east-central Colorado, U.S.A. Eospongilla morrisonensis occurs within the well-developed lacustrine carbonate succession of the Morrison Formation, and is represented by two micritic body fossils with calcite-replaced megascleres that range in length from 180 to 300 μm and in diameter from 20 to 35 μm. Megascleres are simple oxeas and strongyles and lack apparent ornamentation, possibly due to the diagenetic replacement. The oxeas are straight but the strongyles display a slight curvature. Microscleres are absent; gemmoscleres were not observed.

Ptyctodonts from the Upper Devonian Martin Formation on Mt. Elden, northern Arizona, were hitherto known only from tooth plates ascribed toPtyctodus bradyi.Recent collections include dental elements ofP. bradyias well as body and skull plates and dental elements of a previously unknown ptyctodont, described here asDenisonodus plutonensisnew genus and species. Comparison with other ptyctodonts suggests that the new genus has close affinities to other North American forms. As the holotype ofPtyctodus bradyihas been lost a neotype is designated here.

The Family

A new genus and species of Cyphophthalmi, Canga renatae gen. nov., sp. nov., is described in the family Neogoveidae from a system of caves in the Serra de Carajás, Pará State, Brazil. Canga can be easily distinguished from other neogoveid genera by the presence of a dentate claw on leg I, a unique character among known cyphophthalmid species, and by the free coxa II, which is fused to coxae III and IV in all the other neogoveid species except for the North American Metasiro. The new genus also differs from other Neotropical neogoveids in the lack of a dorsal crest on the chelicerae and in the lack of opisthosomal glands. The finding of a neogoveid in the Pará State greatly increases the known distribution of South American cyphophtalmids into the Eastern Brazilian Amazon forest.

We describe the monotypic shield-backed katydid genus Phymonotus and species jacintotopos from the San Jacinto Mountains of southern California, USA. Phymonotus is unique in having an unusually enlarged dome-like pronotum, a distinctive song, and seven additional distinctive morphological features. We believe that Phymonotus is a Pleistocene relic taxon, now endemic to geographically isolated high elevation conifer forests of the San Jacinto Mountains. Nearest relatives Agalothorax and Neduba taxa occur in lower elevation environments throughout the surrounding region. Phymonotus is a member of the katydid tribe Nedubini which has a Gondwanan distribution with additional taxa in Australia and South America (Chile and Argentina). Western North American Nedubini apparently result from a South American dispersal event. We also describe characters newly used for the description and diagnosis of Phymonotus, the dorsal and ventral lobes of the titillators, and the dorsal sclerites of the titillators. We report evidence that Phymonotus males may produce thoracic glandular secretions that are offered to mating females.

New Genus And Species

AbstractA new genus and species of Heptageniidae (Ephemeroptera) is based on a series of nymphs and reared female adults from the Saskatchewan River, Saskatchewan. Descriptions of female and nymphal Macdunnoa nipawinia n. gen., n. sp., of the subfamily Heptageniinae, are given along with notes on the biology. The genus has no close North American relatives, but is allied to heptageniid genera from southeast Asia.
