The type specimens of Pontonides sympathes De Ridder & Holthuis, 1979, Veleronia serratifrons Holthuis, 1951, and V. laevifrons Holthuis, 1951 were re-examined. Pontonides sympathes is transferred to Veleronia Holthuis, 1951, based on morphological similarity with V. serratifrons, the type species of the genus. At the same time, a new genus, Pseudoveleronia gen. nov., is erected for Veleronia laevifrons. Detailed re-descriptions of all studied species as well as a key to the genera Pontonides Borradaile, 1917, Veleronia and Pseudoveleronia gen. nov. are given.

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.

Both the genus Shastasaurus and the family Shastasauridae have long been hard to define due to the fragmentary nature of the type specimens. Consequently, recent interpretations of the genus have been based almost entirely on Shastasaurus neoscapularis from the Late Triassic Pardonet Formation of British Columbia. Two new specimens of this taxon, from Pink Mountain, British Columbia, demonstrate that it does not belong in the genus Shastasaurus. This paper describes the new specimens, and refers the species to Metashastasaurus gen nov. Post-cranially, the skeleton of Metashastasaurus resembles that of shastasaurids, differing primarily only in the shape of the scapula and fibula. However, the skull has a unique combination of characters, including large diamond-shaped frontals that enter the supratemporal fenestrae, and very narrow posterior extensions of the nasals, which contact the postfrontals. It also differs from the skull of Shastasaurus in the presence of both a parietal ridge and postparietal shelf. This is a combination of derived characters previously known only in Jurassic forms. The front limb has four proximal carpals and four digits, indicating that previous reconstructions were based on incomplete material. Shastasaurus pacificus Merriam 1895, the type species of the genus Shastasaurus, must be considered a nomen dubium, making the genus Shastasaurus invalid. Until this problem is clarified, the use of the generic name Shastasaurus should be restricted to Merriam's type specimens, of which only Shastasaurus alexandrae and Shastasaurus osmonti are based on adequate material.

Three New Species

AbstractThe Oriental genus Baptista Distant is redescribed and compared with other genera of Old World Microveliinae. The type-species, B. gesiroi Distant, hitherto only known from the type specimens (from Burma), is redescribed and recorded from Thailand. Three new speeies are described: B. femoralis sp. n. (Thailand, West Malaysia), B. digitata sp. n. (Thailand), and B. angulata sp. n. (southern India). These species all live in very cryptic and secluded habitats, like wet litter, small watery holes in rocks, or small cavities under turf along streams. The males of the new species exhibit a remarkable polymorphism in the structure of fore Iegs and pregenital abdomen. A closely related genus, Lathriovelia gen. n., is described with two species, L. capitata sp. n. and L. collaris sp. n., both from West Malaysia. This genus has a head structure which is quite unique within the subfamily.

Phenotypic Characters

Some Antarctic littorinoideans have a remarkable convergence with Naticoidea in shell and operculum features. Two naticid-like species of that group are studied in their phenotypic features in order to improve their taxonomy and to discuss the meaning of that convergence, as the former are herbivore-detritivore and the latter active predatory organisms. One of the studied species is the littorinidLaevilacunaria antarctica(Martens, 1885). The other belongs to a new genus –Pseudonatica, with the type species also newly described:P. antarctica, the genus is tentatively placed in Zerotulidae. Another Pseudonatica is also described,P. ampullarica, based only on shells collected by Marion-Dufresne French expedition off Brazilian coast, this finding expands the occurrence of zerotulids northwards. Besides the similarities of shell and operculum, other structures of these Antarctic species also show singular similarities with naticoideans, such as the wide foot, the complexity of opercular attachment in pedal opercular pad, the wide oesophageal gland, and the coiled arrangement of the pallial oviduct. The phenotypic characters were coded and inserted in a previous large phylogenetic analysis on Caenogastropoda (Simone, 2011), furnishing a wide basis for discussion on the characters, taxonomic position, evolution and adaptations of these organisms.

Current Information

The type species of the genus Broomea Cookson and Eisenack possesses an intercalary archeopyle formed by loss of a single intercalary paraplate. Species with demonstrable apical archeopyles, formerly assigned to Broomea, are excluded by redefinition of that genus and placed in Batioladinium gen. nov. The taxonomic position of five other species previously assigned to Broomea cannot be resolved on the basis of current information. Transferred to the new genus are Batioladinium jaegeri (Alberti) comb, nov., designated herein as the type species; B. longicornutum (Alberti) comb. nov.; B. micropodum (Eisenack and Cookson) comb. nov.; and provisionally, B.? exiguum (Alberti) comb. nov. and B.? pelliferum (Alberti) comb. nov.

Paraphyletic Assemblage

Species previously attributed to Necrotauliidae are revised from the Late Triassic and Early Jurassic of England based on examination of type specimens and non-type material. The necrotauliids have been considered as a basal family of caddisflies (Trichoptera) or as a paraphyletic assemblage of stem-amphiesmenopterans. Herein a new genus, Austaulius, is erected which includes all Lilstock Formation∖Lower Lias material from England; the previously described species are synonymized with A. furcatus and a new species, A. haustrum, is described from the Dorset Coast, the holotype of which preserves synapomorphic traits of the Trichoptera not previously described suggesting that the family is trichopteran. The type genus remains Necrotaulius and type species N. parvulus (Geinitz, 1884) from the type locality of Dobbertin, Germany. One species of Necrotaulius is represented in the UK, N. parvulus, which is found in the Upper Lias.
