A largely new, Early Mississippian blastoid fauna is described from the Fort Payne Formation of south-central Kentucky and north-central Tennessee. The fauna consists of nine species assigned to eight genera, including four new genera and six new species. The fauna includes Hadroblastus breimeri n. sp., Granatocrinus granulatus (Roemer), Dentiblastus macurdai n. sp., Deliablastus cumberlandensis n. gen. and sp., D. tribulosus n. gen. and sp., Xyeleblastus magnificus n. gen. and sp., Perittoblastus liratus n. gen. and sp., Euryoblastus veryi (Rowley) n. gen., and an unidentifiable basal circlet that may represent a phaenoschismatidid. All spiraculates belong to the Granatocrinidae.The Fort Payne Formation has the most diverse blastoid fauna known between the middle Osagean blastoid extinction and the Permian. Diversification immediately after the middle Osagean extinction is recorded in the Fort Payne and is largely a diversification of the Granatocrinidae.Orbitremites grandis Rowley (1902) is an internal mold from the Fort Payne Formation. This specimen cannot be identified and is designated as a nomen dubium.

Echinoderms of the Middle Ordovician Platteville and lower Galena Groups of north-central Illinois and south-central Wisconsin are represented by at least seven classes including the Homoiostelea, Cystoidea, Crinoidea, Stelleroidea, Edrioasteroidea, Cyclocystoidea, Echinoidea, and possibly Holothuroidea. The most abundant and diverse echinoderms are monocyclic and dicyclic inadunate and camerate crinoids, of which the cupulocrinids and glyptocrinids are best represented. Thirteen new species and one new genus of crinoids are described:Cremacrinus guttenbergensis, Anulocrinus forrestonensis, Isotomocrinus minutus, Carabocrinus oogyi, Dendrocrinus? springeri, Merocrinus britonensis, Cupulocrinus plattevillensis, C. molanderi, Reteocrinus rocktonensis, R. spinosus, Traskocrinus mahlburgi(n. gen. et sp.),Rhaphanocrinus buckleyi, Glyptocrinus charltoni, andG. pustulosis.One new species of rhombiferan cystoid,Coronocystis durandensis, is also described. Echinoids of the family Bothriocidaridae (Bothriocidaris solemin. sp. andNeobothriocidaris templetonin. sp.) are reported for the first time from North America and appear to be the earliest recorded occurrence. Remains of a third bothriocidarid characterized by coalesced podial pores have also been discovered. Light and scanning electron microscopy of well preserved cyclocystoid specimens reveal a number of previously undescribed morphologic features of the central disc and submarginal ring that may shed some light on their functional morphology.Cupulocrinus gracilisRamsbottom from the Upper Drummuck Group Starfish Bed at Thraive Glen near Girvan, Scotland, is here reassigned toC. drummuckensisn. sp.Echinoderms are associated with an abundant and diverse fauna consisting largely of suspension feeders, primarily strophomenid and orthid brachiopods and trepostome and cryptostome bryozoans. Other common groups include corals, trilobites, sponges, and mollusks. Filamentous brown, foliose red and siphonaceous green algae are associated with the fauna at some localities.Carbonate rocks of both the limestone and dolostone facies of the Platteville (Briton, Walgreen and Forreston Members) and lower Galene Groups in the study area consist primarily of abundant shelly invertebrates occurring as whole and broken, unabraded, commonly articulated remains “floating” in a calcisiltite matrix that is highly bioturbated. Carbonate sediments appear to have been deposited in a near-to below wave base, highly stable, open marine environment characterized by low depositional slopes, good circulation and low terrigenous influx.

Abstract The mirine plant bug genus Prolygus Carvalho, 1987 (Hemiptera: Heteroptera: Miridae: Mirinae: Mirini) and superficially reminiscent taxa in eastern Asia (mainly in Japan, P. R. China and Taiwan) are reviewed. Four species in the region are now assigned to Prolygus. Three new genera, Anthophilolygus gen. nov., Miyamotolygus gen. nov. and Poppiolygus gen. nov., are proposed to accommodate Prolygus bakeri (Poppius, 1915), Neolygus rufilorum (Lu & Zheng, 2004) and Lygus bengalicus Reuter, 1885, respectively. Ten new combinations and three new synonymies are established: Apolygopsis eoa (Poppius, 1915) comb. nov. [transferred from Apolygus China, 1941]; A. fuhoshoensis (Poppius, 1915) comb. nov. [Apolygus]; A. nigra (Poppius, 1915) comb. nov. [Prolygus]; Anthophilolygus bakeri (Poppius, 1915) comb. nov. [Prolygus] = P. tainanensis (Poppius, 1915) syn. nov.; Micromimetus rubrotinctus (Carvalho, 1956) comb. nov. [Lygus sensu lato]; Miyamotolygus bui (Lu & Zheng, 2004) comb. nov. [Neolygus Knight, 1917]; M. pictus (Lu & Zheng, 2004) comb. nov. [Neolygus]; M. rufilorum (Lu & Zheng, 2004) comb. nov. [Neolygus]; Poppiolygus bengalicus (Reuter, 1885) comb. nov. [Lygus sensu lato] = Prolygus kirkaldyi (Poppius, 1915) syn. nov.; Prolygus disciger (Poppius, 1915) comb. nov. [Neolygus]; P. palauensis (Carvalho, 1956) comb. nov. [Lygus sensu lato]; P. nigriclavus (Poppius, 1915) = Neolygus nigroscutellaris (Lu & Zheng, 2004) syn. nov. Two additional new species, Anthophilolygus alaneylesi sp. nov. (central Thailand) and Micromimetus sunweni sp. nov. (Lanyu Island, Taiwan), are also described. The lectotype is designated for Lygus bengalicus Reuter. Lygus sacchari Matsumura, 1910 is regarded as nomen dubium.

Desmoinesian strata of the lower Bishop Cap Formation in Vinton Canyon, northern Franklin Mountains, west Texas, contain a rich gastropod fauna, in general resembling that of the upper Flechado Formation in north-central New Mexico. Distinctive elements of the Bishop Cap fauna include two new genera and five new species. Each species is represented by 30 or more specimens, sufficient to document ontogenetic change and intraspecific variability. The new taxa described here include the murchisonioid Altadema convexa new genus and species; the pseudozygopleurids Microptychis insolita new species, Trepsipleura chordanodosa new genus and species, and T. nodosa new species; and the orthonemid Hermosanema carinatum new species.

The genera Deltaspis Audinet-Serville, 1834 and Muscidora, Thomson, 1864 (Coleoptera: Cerambycidae: Cerambycinae: Trachyderini) are revised. Two new genera Neoxoplus gen. nov. and Deltaspiopsis gen. nov., are described. Two species previously included in Deltaspis [D. cruentus, (LeConte, 1862), and D. ivae Beierl & Barchet-Beierl, 1999] are transferred to the new genus Neoxoplus with N. cruentus designated as the type species. Four other Deltaspis species [D. alutacea Bates, 1885, D. marginella Bates, 1891, D. nigripennis Bates, 1880, and D. tumacacorii (Knull, 1944)] are transferred to Muscidora Thomson, 1864. Two species [D. disparilis Bates, 1891, and D. variabilis Bates, 1891] are transferred to the new genus Deltaspiopsis with D. disparilis designated as type species, and the remaining species [D. moesta Bates, 1885, D. rubens Bates, 1885, and D. subopaca Chemsak & Linsley, 1982] are transferred to Crossidius LeConte, 1851. Keys to closely related genera, above mentioned genera and species along with illustrations of the available species in color are included. New species described include: Muscidora bezarki sp. nov. from south-central Mexico (Puebla, Oaxaca); Muscidora coriacea sp. nov. from southeastern Mexico (Oaxaca and Chiapas); Muscidora nigrescens clinei subsp. nov. (Jalisco); and Muscidora similis sp. nov. from western Mexico (Sinaloa and Sonora).

The bryocorine genus Caulotops Bergroth (Miridae: Eccritotarsini), originally described to accommodate its only species C. puncticollis Bergroth, is shown not to be congeneric with all other species now included in the genus from North, Central, and northern South America. Consequently, four new genera are established for the following 20 species, including five new combinations and 14 species described as new: Agaveocoris n. gen. for Caulotops agavis Reuter (as the type species), n. comb.; C. barberi Knight, n. comb.; and C. distanti Reuter, n. comb. and the new species A. bimaculatus, n. sp.; A. barrerai, n. sp.; A. dimidiatus, n. sp.; A. marginalis, n. sp.; A. roseus, n. sp.; A. rostratus, n. sp.; A. schaffneri, n. sp.; and A. scutellatus, n. sp; Laterospinocoris, n. gen. for Caulotops cyaneipennis Reuter, new comb. (as the type species) and the new species L. mexicanus, n. sp.; Nigrotomocoris n. gen. for Caulotops nigrus Carvalho (as the type species), n. comb.; C. tibiopallidus Carvalho, n. comb.; and the new species N. keltoni, n. sp. and N. longirostris, n. sp.; and Schaffnerocoris, n. gen., for S. fuscotibialis, n. sp. (as the type species), S. pallipes, n. sp., and S. similis, n. sp. Lectotypes are designated for Caulotops agavis Reuter, Caulotops cyaneipennis Reuter, and Caulotops puncticollis Bergroth, and a neotype is designated for Eccritotarsus platensis Berg. Each genus and species is diagnosed and described; habitus images, illustration of male genitalia and selected female genitalia, and keys to genera and species are provided; and host use and the unique genitalic systems of these taxa are discussed. A phylogenetic analysis, based on 22 taxa and 39 characters, resulted in three trees supporting the monophyly of the four new genera proposed in this study.

Three New Species

Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.
