Each of the seven families of rudists (Mollusca, Bivalvia, Hippuritacea) is characterized by distinctive shell-wall architectures which reflect phylogenetic relationships within the superfamily. Analysis of the complex, calcareous, cellular wall of the attached valve of the radiolite rudist Eoradiolites davidsoni (Hill) from the Comanche Cretaceous of Central Texas indicates that its wall architecture is an elaboration of the simpler monopleurid rudist wall and supports possible radiolite-monopleurid relationships.Several well-preserved specimens of E. davidsoni were sectioned, polished, etched, and carbon and gold coated for SEM examination. Maximum shell microstructure detail was displayed by etching with a 0.7% HC1 solution from 80 to 100 seconds.The shell of E. davidsoni comprises a large, thick-walled, conical, attached valve (AV) and a small, very thin, operculate, free valve (FV) (Fig. 1a). The AV shell is two-layered with a thin inner wall, in which original structures are usually obliterated by recrystallization, and a thick, cellular, outer wall.

The genus Trichadenotecnum Enderlein, 1909 is redefined as a monophyletic group. The following 22 Japanese species are treated and classified into five species-groups except one species not placed in a group: sexpunctatum-group – T. album, sp. nov., T. incognitum Roesler, 1939; medium-group – T. takahashii, sp. nov., T. mixtum, sp. nov., T. magnomixtum, sp. nov., T. amamiense, sp. nov., T. okinawense, sp. nov., T. yonaguniense, sp. nov., T. kumejimense, sp. nov., T. latebrachium, sp. nov., T. pseudomedium, sp. nov., T. yaeyamense, sp. nov.; alexanderae-group – T. alexanderae Sommerman, 1948, T. castum Betz, 1983, T. sexpunctellum (Enderlein, 1907); majus-group – T. yamatomajus, sp. nov., T. nothoapertum, sp. nov.; spiniserrulum-group – T. falx, sp. nov., T. furcalingum, sp. nov., T. pardidum Thornton, 1961, T. circularoides Badonnel, 1955; incertae sedis – T. fuscipennis, sp. nov. The monophyly and phylogenetic relationships of these species-groups are discussed. A key to Japanese species of Trichadenotecnum is given.

AbstractIn the 1950s, Carlos Rusconi reported the biostratigraphically important Furongian trilobites Elvinia Walcott and Irvingella Ulrich and Resser from an exotic limestone block (La Cruz Olistolith) of the San Isidro area, Precordillera of Mendoza, western Argentina. Although several local species were erected by Rusconi at that time, most of them were later listed as junior synonyms of E. roemeri (Shumard) or I. major Ulrich and Resser, and this was followed in subsequent studies. A systematic revision of all the available specimens of Elvinia and Irvingella from the Rusconi collection at the Museo de Ciencias Naturales y Antropológicas J.C. Moyano (Mendoza) is provided herein. The occurrence of E. roemeri is supported by the present study, while the associated Irvingella species include I. jorusconii Rusconi, I. platycephala Rusconi, and Irvingella sp. The latter represent “advanced” forms in terms of morphological development in the Irvingella lineage, and these, together with E. roemeri, are typical of the uppermost part of the Elvinia Zone (uppermost Steptoean). Irvingella jorusconii, I. platycephala, and Irvingella sp. appear to be endemic to the Argentinian Precordillera, but are related to species from central Texas and northwest Canada.

One New Species

The New Zealand endemic longicorn beetle genus Drototelus Broun is revised. The scope of the genus is redefined. The monotypic genus Neocalliprason Brookes is synonymised with Drototelus. Two known species, D. politus Broun and D. elegans (Brookes), are redescribed and one new species, D. rarus, is described. These changes have brought the number of Drototelus species to three. Distribution and biology are noted for each species. Adults are diurnally active flower-visitors, and larvae are dead-wood feeders. Phylogenetic relationships of these species are cladistically analysed, confirming the monophyly of the revised genus and determining the sister-species relationship between D. politus and D. rarus.

Systematic revision and phylogenetic reassessment of the centipede genera Rhysida Wood, 1862 and Alluropus Silvestri, 1912 (Chilopoda: Scolopendromorpha) in Southeast Asia, with further discussion of the subfamily Otostigminae

Phylogenetic relationships of two morphologically similar scolopendrid genera, Rhysida Wood, 1862, and Alluropus Silvestri, 1912, were investigated based on broad-scale taxonomic sampling from SE Asia, India and Australia. Morphological revision and molecular phylogenetics using three loci validate seven Rhysida species in SE Asia and Australia: R. lithobioides (Newport, 1845), R. longipes (Newport, 1845), R. immarginata (Porat, 1876), R. nuda (Newport, 1845), R. carinulata (Haase, 1887), R. singaporiensis Verhoeff, 1937 and R. polyacantha Koch, 1985. The nominal SE Asian species R. leviventer Attems, 1953 and R. marginata Attems, 1953 are placed in junior subjective synonymy with R. lithobioides and Alluropus calcaratus (Pocock, 1891), respectively. The monotypic genus Alluropus is redescribed, molecular phylogeny recovering it nesting together with Indo-Australian Rhysida. Taxonomic revision reassigned R. calcarata Pocock, 1891 to Alluropus based on its morphological and molecular similarity to the type, A. demangei Silvestri, 1912, the differences between putative species being sexual variation. Two morphologically distinct allopatric populations of A. calcaratus, comb. nov. (= A. demangei, syn. nov.) were found in the Indochina subregion. Phylogenetic relationships in Otostigminae remain unsettled because clades within several genera lack significant support, although Rhysida consistently falls into two clades that are not each other’s closest relative.

Thirty-five species are recognized in the Neotropical genus Anopinella Powell, including 5 previously described, A. isodelta (Meyrick), A. triquetra (Walsingham), A. ophiodes (Walsingham), A. aurea (Razowski & Becker), new combination, and A. perblanda (Razowski & Becker), new combination, and 30 described as new: A. albolinea (TL: Costa Rica), A. araguana (TL: Venezuela), A. arenalana (TL: Costa Rica), A. boliviana (TL: Bolivia), A. brasiliana (TL: Brazil), A. cafrosana (TL: Costa Rica), A. cartagoa (TL: Costa Rica), A. carabayana (TL: Peru), A. choko (TL: Colombia), A. cuzco (TL: Peru), A. fana (TL: Venezuela), A. holandia (TL: Guatemala), A. larana (TL: Venezuela), A. macrosema (TL: Costa Rica), A. mariana (TL: Guatemala), A. panamana (TL: Panama), A. parambana (TL: Ecuador), A. peruvensis (TL: Peru), A. phillipsae (TL: Costa Rica), A. porrasa (TL: Costa Rica), A. powelli (TL: Costa Rica), A. rastafariana (TL: Jamaica), A. razowskii (TL: Brazil), A. rica (TL: Costa Rica), A. rigidana (TL: Costa Rica), A. styraxivora (TL: Costa Rica), A. sympatrica (TL: Guatemala), A. tinalandana (TL: Ecuador), A. transecta (TL: Costa Rica), and A. tucki (TL: Peru). The genus occurs from Jamaica and southern Mexico to southern Brazil, Paraguay, and Bolivia. One species has been reared from the fruit of Styrax (Styracaceae), one from a fungus gall on Inga longispina (Fabaceae), and one from the stem of Vernonia (Asteraceae). We re-examine phylogenetic relationships among Anopinella and its putative related genera, Seticosta Razowski, Punctapinella Brown, Strophotina Brown, and Apolychrosis Amsel. We synonymize Ecuadorica Razowski & Becker, 2000, with Anopinella.
