The Family

Lamprortus orientalis Rodriguez gen.nov., sp.nov. is identifiable as a member of the Lumbriculidae by virtue of the prosoporous male ducts, but is unique in the family, as it is consistently hologynous. The elongate atria, single vas deferens on each atrium, and spermathecae located in the post-ovarian segment indicate a relationship to Lamprodrilus and related genera distributed from Siberia through eastern Asia to western North America.

AbstractThe western Nearctic genera Neothremma and Farula are assigned to the family Uenoidae, previously comprising only the type genus Uenoa from Asia; a new genus Sericostriata with S. surdickae n. sp. from western North America is also added to the family. Traditionally assigned to the Limnephilidae where they have been always anomalous, Neothremma and Farula are shown to share many synapomorphic larval characters with Uenoa; under close examination, characters of the adults support this relationship. Familial and generic diagnoses are provided, reflecting the revised composition of the Uenoidae. Generic keys to adults, larvae, and pupae are given; species are briefly reviewed and keys given to adults; Uenoa arcuata n. sp. is described from Assam, Uenoa janetscheki Botosaneanu is placed as a junior subjective synonym under U. hiberna Kimmins, and Neothremma laloukesi Schmid as a junior subjective synonym of N. alicia Dodds and Hisaw. Phylogenetic relationships among the genera are considered. This study is an instructive example of the importance of larvae in providing data for the systematics of Trichoptera.

One New Species

AbstractOne new genus of Inocelliidae (Raphidioptera) with one new species and one undetermined specimen is described from the Eocene of North America: Paraksenocellia borealis new genus, new species from the early Eocene (Ypresian) Okanagan Highlands shale at Driftwood Canyon, British Columbia, Canada (a forewing), and Paraksenocellia species from the middle Eocene (Lutetian) of the Coal Creek Member of the Kishenehn Formation, northwestern Montana, United States of America (a hind wing). These are the oldest records of the family. The new genus possesses many character states that are rare in Inocelliidae, e.g., a very long pterostigma extending to ScP in both the forewings and hind wings; the forewing subcostal space has three crossveins; the forewing and hind wing AA1 are deeply forked; the crossvein between CuA and CuP is located far distad the crossvein 1r-m. Paraksenocellia is confidently a member of the Inocelliidae, as it possesses a proximal shift of the basal crossvein 1r-m (connecting R and M) in the forewing and the loss of the basal crossvein 1r-m in the hind wing, both apomorphies of the family. It shares some character states with the Mesozoic Mesoraphidiidae, which we consider to be mostly stem-group plesiomorphies.

New Synonymy

AbstractThe systematic status of the genus Tarsocheylus Berlese, 1904 and the position of the family Tarsocheylidae Atyeo and Baker, 1964 in the Prostigmata is reviewed. The family does not belong in either the Raphignathoidea or the Anystoidea but in its own superfamily, the Tarsocheyloidea, which is described for this purpose. In turn, this superfamily is placed alongside the Heterocheyloidea in the Heterostigmata.Because the type-species of Tarsocheylus, T. paradoxus Berlese, 1904, is conspecific with Hoplocheylus discalis Atyeo and Baker, 1964 (new synonymy), the concept of Hoplocheylus Atyeo and Baker, 1964, which has remained until now as originally proposed, is the same as that of Tarsocheylus. However, a new case is made for recognizing these genera as mutually distinct, based on other morphological criteria. Tarsocheylus atomarius Berlese, 1913, the type-species of Hoplocheylus, is apparently conspecific with Hoplocheylus canadensis Marshall, 1966 (new synonymy) and perhaps with one or two other described species from North America. A third generic entity, represented by Hoplocheylus johnstoni Atyeo and Baker, 1964, is noted but not named or formally described. Hoplocheylus pickardi Smiley and Moser, 1968 is conspecific with H. similis Delfinado and Baker, 1974 (new synonymy).Hemitarsocheylus Soliman and Zaher, 1975, which was described as a new genus in the Tarsocheylidae, is congeneric with Stigmocheylus Berlese, 1910 (new synonymy). This genus does not belong in the Tarsocheyloidea, but rather in the Anystoidea.A list of character states found useful in recognizing groupings of species of Tarsocheylidae is presented. Based on the collection data with specimens representing described and undescribed species at hand, the known distribution of the Tarsocheylidae is extended to include Australia and western North America, and the second known instance of an association with passalid beetles is recorded.From a phylogenetic standpoint, the Tarsocheyloidea and Heterocheyloidea are proposed as sister groups that together constitute a new suprafamilial taxon, the Tarsocheylina. In turn, the Tarsocheylina and Tarsonemina are proposed as sister groups, and both are described; together, they form the Heterostigmata.The systematic and phylogenetic relationships of the Heterostigmata (including the Tarsonemina) to the Prostigmata and the Astigmata are reviewed. Not only should the Heterostigmata be retained in the Prostigmata but it should be lowered in hierarchic rank, such that it is a part of the Eleutherengona. The stock that gave rise to the Anystoidea and related superfamilies is shown to be ancestral to the Heterostigmata as well.

First Time

Cocks and Rong (1989) subdivided the species of the Ordovician brachiopod genus Bimuria into two groups, those with a simple, or not undercut, cardinal process and those with an undercut cardinal process. They placed the second group in a new genus, Cooperea, and grouped Cooperea with Craspedelia in the new subfamily Craspedeliinae of the family Sowerbyellidae. However, the cardinal process of Bimuria ranges from not undercut to undercut within at least two species. Cooperea is therefore placed in synonymy with Bimuria, and Craspedelia is returned to the Bimuriidae.Cocks and Rong (1989) inferred that, with rare exceptions, the cardinal process of the Plectambonitacea evolved from simple to trifid to undercut. The evidence from Bimuria indicates, however, that the undercut process developed more than once and, in Bimuria, directly from the simple type.As an adjunct to the above discussion three new species are described: Bimuria gilbertella, Craspedelia intonsa, and Craspedelia sp. 1. Craspedelia is a rarely reported genus documented here for the first time in western North America (northern California). Additional evidence is introduced that the ratio Lmusbv/Lebv decreased from middle to late Ordovician species of Bimuria.

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.

Review of recently collected material of Eohiodon from North America suggests that there are two valid species, E. rosei (Hussakof) and E. woodroffi Wilson. Eohiodon falcatus Grande is identical to E. woodruffi in known skeletal features and nearly all meristic features and is treated as a junior synonym of the latter. The fossil genus Eohiodon Cavender differs from Hiodon Lesueur, which is known from both fossil and extant species, in numerous meristic and osteological features. The caudal skeleton in Eohiodon is nearly identical to that in Hiodon.The traditionally accepted Notopteroidei, containing Lycopteridae, Hiodontidae, and Notopteridae, is a polypheletic group. The Asian fossil family Lycopteridae is not more closely related to Hiodontidae than it is to other taxa in the Osteoglossomorpha, but is sister to all other Osteoglossomorpha. The Hiodontiformes sensu stricto, including only the family Hiodontidae, is the sister-group of the Osteoglossiformes. This family is not more closely related to notopterids than to other taxa in Osteoglossiformes. The Notopteridae are most closely related to the Mormyroidea; together they and the fossil family Ostariostomidae constitute the sister-group of the Osteoglossoidei.Fossil records of Hiodontiformes sensu stricto and Notopteroidei indicate a widespread pre-Neogene biogeographic range of these freshwater teleosts, suggesting that extinction must have been involved in the Cenozoic evolution of these two osteoglossomorph sublineages.

Nomen Dubium

Kochaspids are an informal group of ptychopariid trilobites that were both abundant and widespread in the early Middle Cambrian of North America. Based on the reassociation of pygidia and cranidia of some kochaspids, Kochiella Poulsen, 1927, is redefined and Hadrocephalites n. gen. is proposed. Hadrocephalites includes taxa previously assigned by Rasetti and Palmer to Schistometopus Resser, 1938a. Schistometopus is considered nomen dubium. Representatives of Kochiella and Hadrocephalites from the Pioche Shale and Carrara Formation of Nevada are described, including the new species Kochiella rasettii, K. brevaspis, Hadrocephalites lyndonensis, and H. rhytidodes. Other kochaspids previously assigned to Kochaspis Resser, 1935; Eiffelaspis Chang, 1963; Schistometopus; and Kochiella are discussed and some are reassigned. The type specimens of Kochiella augusta (Walcott, 1886); K. crito (Walcott, 1917b); K. chares (Walcott, 1917a); K. mansfieldi Resser, 1939; K. arenosa Resser, 1939; Hadrocephalites carina (Walcott, 1917b), and H. cecinna (Walcott, 1917b) are re-illustrated.

Notch Peak

The Notch Peak Formation (Late Cambrian, Sunwaptan) of western Utah yields diverse silicified trilobite faunas that provide new information on the anatomy of many taxa. The family Ptychaspididae Raymond, 1924, is represented by species of Keithiella Rasetti, 1944; Idiomesus Raymond, 1924; Euptychaspis Ulrich in Bridge, 1931; and Macronoda Lochman, 1964. At least four species are new, of which E. lawsonensis and M. notchpeakensis are named formally. Much previous work on Late Cambrian trilobites has emphasized biostratigraphic utility and the recognition of geographically widespread species. Data from new silicified collections indicate that this approach is difficult to justify because many putative ‘index species’ actually represent a plexus of closely related species whose biostratigraphic significance has yet to be determined. One such plexus is represented by E. kirki Kobayashi, 1935, whose previously reported occurrences in Texas, Oklahoma, Utah, Nevada and northern Canada record at least four distinct species. Similarly, Macronoda can now be shown to consist of at least five late Sunwaptan species in south-central and western North America.

Two species of a new genus of Rhinebothriidea have been collected from species of Psammobatis Günther along the coast of Argentina. Semiorbiseptum gen. nov. is considered a rhinebothriidean for the presence of facially loculated bothridia borne on stalks and cirrus covered with spinitriches. The genus is unique in the arrangement of loculi and septa on the distal bothridial surface, including semicircular septa in the middle region. Despite the anterior-posterior orientation of bothridia, Semiorbiseptum gen. nov. fits well in the description of the family Rhinebothriidae by lacking a myzorhynchus at the adult stage and postvaginal testes, and by having vitelline follicles that are not interrupted at the level of the ovary. The two new species differ from each other in the number of facial bothridial loculi and in the microthrix pattern on the proximal bothridial surface. Unlike the majority of rhinebothrideans in the marine environment, which show high specificity for their definitive host, Semiorbiseptum mariae sp. nov. was found in two species of Psammobatis, the smallthorn sand skate Psammobatis rudis Günther and shortfin sand skate Psammobatis normani McEachran. These species have a sympatric distribution, similar to the hosts of most rhinebothrideans that parasitize more than one host. On the contrary, Semiorbiseptum alfredoi sp. nov. was found only in P. normani. This study shows that some of the characters previously proposed as possible synapomorphies for the order have interspecific variability or can be equivocally interpreted (e.g. the entrance of the vas deferens into the cirrus sac, bothridial stalk shape).
