ABSTRACTSeven new species and one new genus of the family Haplolepidae (Actinopterygii: Palaeonisciformes) are described from new material obtained from the Drumgray coal shales, North Lanarkshire: Westphalian A (Bashkirian): Protohaplolepis isabellae; Protohaplolepis limnades; Protohaplolepis traquairi; Parahaplolepis alexandrae; Parahaplolepis elenae; Pyritocephalus youngii and Millerolepis eleionomae. The discovery of these new taxa increases the number of haplolepid species found in Europe to 16, thus producing a faunal count more than comparable to that of North America. This high concentration of haplolepid remains in limnic deposits is also a strong indication that these fish were not only adapted to a coastal paralic basin, but also well-adapted to a freshwater brackish environment. A comprehensive description of the skull roof morphology, including a short description of some of the larger dermal bones, is given of seven new haplolepid species obtained from the coal shale tips at Wester Bracco and Shotts in North Lanarkshire. In consequence, a revised table of the stratigraphical distribution of the Haplolepidae in Europe is provided. Furthermore, the new genus Millerolepis is assigned to the subfamily Parahaplolepinae and the generic position of the problematic Haplolepis attheyi from Newsham, Northumberland is discussed, with the taxonomic position of Protohaplolepis proposed.

Several species of the family Xeniidae, previously assigned to the genus Cespitularia Milne Edwards & Haime, 1850 are revised. Based on the problematical identity and status of the type of this genus, it became apparent that the literature has introduced misperceptions concerning its diagnosis. A consequent examination of the type colonies of Cespitularia coerulea May, 1898 has led to the establishment of the new genus Conglomeratuscleragen. n. and similarly to the assignment of Cespitularia simplex Thomson & Dean, 1931 to the new genus, Caementabundagen. n. Both new genera are described and depicted and both feature unique sclerite morphology, further highlighting the importance of sclerite microstructure for generic position among Xeniidae. Freshly collected material was subjected to molecular phylogenetic analysis, whose results substantiated the taxonomic assignment of the new genera, as well as the synonymies of several others.

Composite Restoration

The isolated skull of a Lower Carboniferous anthracosaur labyrinthodont from the Midlothian coalfield was formerly but erroneously attributed to Pholidogaster pisciformis . It is now redescribed after ‘Airbrasive’ development as the holotype of a new genus and species. The anthracosaur agrees in a number of diagnostic cranial characters with the embolomerous forms of the Coal Measures but other characters, particularly those of the braincase and lower jaw, suggest relationship to the Seymouriamorpha. Its cranial anatomy could well be antecedent to that of both these groups and the sparse evidence available suggests close relationship to the American Mississippian anthracosaur Proterogyrinus . A new classification of the Batrachosauria is presented with a major subdivision into Anthracosauria and Seymouriamorpha. The former group comprises the newly proposed infraorder Herpetospondyli to include the Lower Carboniferous forms, together with the infraorders Embolomeri and Gephyrostegoidea. It is concluded that while no batrachosaur with an otic notch could be a reptile ancestor a primitive ‘notchless’ anthracosaur could be. The cranial anatomy of Pholidogaster pisciformis is then redescribed, after complete ‘Airbrasive’ preparation of the holotype skull. The holotype, like the anthracosaur, comes from the Gilmerton Ironstone of the Edinburgh region, but the earlier holotype skull of Otocratia modesta , long considered to be an ichthyostegid, is also attributed to Pholidogaster . After redescription of ‘ Otocratia ' a composite restoration of the Pholidogaster skull is presented. The nature of the dermal ornament, the post-parietal-supratemporal suture, the absence of tabular horns and the nature of the post-cranial skeleton all demonstrate that Pholidogaster is an early temnospondyl labyrinthodont in no way closely related to anthracosaurs. It is closely similar to the American Mississippian form Greererpeton burkemorani Romer, notably in the presence of large premaxillary fangs and the absence of otic notch and intertemporal. Both may be attributed to the family Colosteidae. It is concluded that there is no strong evidence of close relationship between the colosteids and the Devonian ichthyostegids.

Morphological And Molecular Data

In this paper we introduce Neoaquastroma, a novel genus from dead twigs, collected in northern Thailand. The genus is characterized by immersed, globose to subglobose or irregular-shaped ascomata, short papillate ostioles, a thin peridium, clavate asci with short pedicels, and multi-septate, hyaline ascospores with guttules in each cell. The morphological character differences and analyses of combined LSU, TEF, SSU and ITS sequence datasets, from a single ascospore isolate, support the validity of the new genus and its placement in Parabambusicolaceae. The new genus is compared with other genera in the family and a comprehensive description, and micrographs are provided.

The genusLaomediaDe Haan, 1841 of the family Laomediidae Borradaile, 1903 includes four known species,L. astacinaDe Haan, 1841,L. healyiYaldwyn & Wear, 1970,L. paucispinosaNgoc-Ho, 1997, andL. barronensisNgoc-Ho & Yaldwyn, 1997. Herein, a fifth, possibly new species is described that, because of the lack of undamaged, adult specimens and the absence of locality data, is designated provisionally asLaomediasp. A. Furthermore, an extended description ofLaomedia astacinais provided, based on new material from Japan and also a newly revised key to the species of the genusLaomediais presented. In addition, a new genus,Heteroaxianassagen. nov., is proposed.

New fossils referable to the Cancridae Latreille, 1802 extend the known stratigraphic range of the family into the middle Eocene and the geographic range into South America. Each genus within the family has been reevaluated within the context of the new material. A suite of diagnostic characters for each cancrid genus makes it possible to assign both extant and fossil specimens to genera and the two cancrid subfamilies, the Cancrinae Latreille, 1802, and Lobocarcininae Beurlen, 1930, based solely upon dorsal carapace morphology. Cheliped morphology is useful in assigning genera to the family but is significantly less useful at the subfamily and generic level. Each of the four subgenera sensu Nations (1975), Cancer Linnaeus, 1758, Glebocarcinus Nations, 1975, Metacarcinus A. Milne Edwards, 1862, and Romaleon Gistl, 1848, are elevated to full generic status. Additionally, three new genera and three new species accommodate the new, as well as some previously described taxa, and include Anatolikos new genus, Anisospinos berglundi new genus and species, and Notocarcinus sulcatus new genus and species and several new combinations. Recognition of new genera and reassignment of several species within the Cancrinae indicates that that subfamily may have arisen in the southern hemisphere, contrary to the previous interpretation of the subfamily as a primarily North Pacific or Tethyan group. The Lobocarcininae was primarily a Tethyan group.

The family of mygalomorph spiders Paratropididae Simon, 1889 is here reported for the first time for Colombia, where it is represented by three genera (Anisaspis, Paratropis, Stormtropisgen. n.) and eight species. One genus, Stormtropis, and six species constitute new taxa that are here diagnosed, described and illustrated. The geographical distribution of Paratropispapilligera FO Pickard-Cambridge, 1896 and Paratropiselicioi Dupérré, 2015 are also redescribed and expanded on the basis of new material examined. The diagnosis of the subfamily Paratropidinae, Paratropis Simon, 1889 and Anisaspis Simon, 1892 are emended including the variations of the new species. Likewise, a geographic distribution map for the entire family and a taxonomic key for the males of Paratropidinae are included. Other biogeographic, morphological, and taxonomic aspects are discussed.

Premilcurensis senecionis gen. et and sp. nov. was collected on stems of Senecio sp. from Forlì-Cesena Province, Italy and is introduced in Phaeosphaeriaceae with the support of a unique combination of morphological characters and combined gene phylogenetic analyses. Premilcurensis is distinguished from other genera in Phaeosphaeriaceae in having fusiform to cylindrical, hyaline to yellow-green ascospores with 3–5 septa, and mucilaginous, wing-like appendages at the central septum. Phylogenies analyses show Premilcurensis as a distinct lineage from other genera in the family Phaeosphaeriaceae with high bootstrap support. A comprehensive description and micrographs of P. senecionis is provided and the new genus is compared with morphologically similar taxa.

A new eastern-palaearctic monotypic genus of the gelechioid moths, Paralypusa gen. nov., is established for the Chinese species Paralypusa chinensis (Lvovsky, 2010), comb. nov. This genus is considered closely related to Lypusa Zeller, 1852 on the base of several synapomorphies. However Paralypusa also shares some features with the genera Pseudatemelia Rebel, 1910 and Amphisbatis Zeller, 1870. Its transitional state confirms the belonging of all the aforementioned genera to one family and synonymy of the Lypusidae Herrich-Schäffer, 1857 and Amphisbatidae Spuler, 1910 (Nieukerken et al., 2011).
