Loricate choanoflagellates (Acanthoecida) from warm water seas. IX. Coronoeca gen. nov., Polyfibula Manton and spiny forms of Parvicorbicula Deflandre

The ambition to generate an overview of warm water loricate choanoflagellate biodiversity, based on a classic morphometric approach, is here completed by analyses of a range of tiny forms with anterior spines or projections and in most cases also a posterior pedicel. The warm water study complements previously obtained results from the more extensively studied temperate and polar regions of the world’s oceans. It thus contributes to a significantly more balanced approach to global diversity patterns for these organisms. The current survey includes taxa such as Polyfibula elatensis, Parvicorbicula pedicellata, as well as a range of primarily undescribed and taxonomically challenging species, that are in an interim approach allocated to Coronoeca gen. nov. (C. kosmaniae sp. nov., C. conicella sp. nov., C. superpositus (Booth) comb. nov., C. marchantii sp. nov., C. tongiae sp. nov., and C. patongiensis sp. nov.). The analysis of warm water acanthoecid biodiversity has revealed in total 80 species from the six geographic regions sampled, corresponding to approximately 50% of all loricate species described. Nineteen species are previously undescribed forms. The Andaman Sea, Thailand, and West Australia are in a global context the most species-rich regions with 62 and 64 species respectively.     

New radiolaria of the family Pseudodictyomitridae from the Coniacian-Santonian of the Perapedhi Formation of southern Cyprus

A new genus of Late Cretaceous radiolarians, Cyprodictyomitra gen. nov., comprising two new species, C. longa sp. nov., C. elegantissima sp. nov., and a new species, Pseudodictyomitra crassa sp. nov. are described.

Three new species of genus Myrmica (Hymenoptera: Formicidae) from Himalaya

Three new species of the genus Myrmica are described from the Himalayas. Myrmica curvispinosa sp. nov., Myrmica kothiensis sp. nov. and Myrmica religiosa sp. nov. belong to the Myrmica inezae species group, which is earlier represented by 4 species. Myrmica curvispinosa sp. nov. is described based on worker and gyne, with a report of ergatoid as well. Myrmica kothiensis sp. nov. and Myrmica religiosa sp. nov. are described based on worker caste only. A key to the species of the Myrmica inezae species group has been provided in the following.     

The genus Cyprideis Jones, 1857 (Crustacea,Ostracoda) in the Neogene of Italy: A geometric morphometric approach

As a result of the use of geometric morphometrics, multivariate statistics and classical morphological observations the authors propose a taxonomic revision of the Neogene Italian Cyprideis species. On this basis, the Cyprideis valves collected in Tortonian, Messinian and Pliocene brackish deposits of Italy are referred to 12 species, six of which are new: Cyprideis alexandri nov. sp., Cyprideis arvedoi nov. sp., Cyprideis lepianensis nov. sp., Cyprideis rooki nov. sp., Cyprideis strollae nov. sp., and Cyprideis toscana nov. sp. Some species are rather widespread in the Italian Peninsula (Cyprideis ruggierii Decima and Cyprideis crotonensis Decima) or even in the whole Palaeomediterranean (Cyprideis agrigentina Decima and Cyprideis anlavauxensis Carbonnel). For C. ruggierii, C. agrigentina and C. crotonensis, a phyletic relation is suggested. The new species are confined both geographically and stratigraphically in several Tuscan athalassic brackish basins, suggesting endemic speciation similar to those occurring in ancient lakes.

Groupe de Candona clivosa, nouveau groupe de Candoninae (Crustacea, Ostracoda) et sa diversification dans le Bassin de Turiec (Slovaquie) au Miocène supérieur

The Candona clivosa-group, a new group of Candoninae - is erected on the base of the folded inner lamella observed on the postero-ventral border of the female valve. The elongated sub-triangular and rectangular valves of this group are described from the Miocene and Quaternary deposits of Europe. A folded inner lamella is also observed in 11 species of Candona from the Upper Miocene of the Turiec Basin of which 8 are new - Candona fatrica nov. sp., C. tatrica nov. sp., C. lacustris nov. sp., C. palustris nov. sp., C. stagnosa nov. sp., C. laterisimilis nov. sp., C. jiriceki nov. sp. and C. incurva nov. sp. They show a higher variability of the outline, calcification of the valves and width of the zone of concrescence. The extrinsic and intrinsic aspects of this morphological diversification in the Turiec Basin are discussed.     

Integrative Taxonomy and Species Delimitation in Harvestmen: A Revision of the Western North American Genus Sclerobunus (Opiliones: Laniatores: Travunioidea)

Alpha taxonomy, and specifically the delimitation of species, is becoming increasingly objective and integrative. The use of coalescent-based methods applied to genetic data is providing new tools for the discovery and delimitation of species. Here, we use an integrative approach via a combination of discovery-based multivariate morphological analyses to detect potential new species. These potential species are then used as a priori species in hypothesis-driven validation analyses with genetic data. This research focuses on the harvestmen genus Sclerobunus found throughout the mountainous regions of western North America. Based on our analyses, we conduct a revision of Sclerobunus resulting in synonymy of Cyptobunus with Sclerobunus including transfer of S. cavicolens comb. nov. and elevation of both subspecies of S. ungulatus: S. ungulatus comb. nov. and S. madhousensis comb. nov., stat. nov. The three subspecies of S. robustus are elevated, S. robustus, S. glorietus stat. nov., and S. idahoensis stat. nov. Additionally, five new species of Sclerobunus are described from New Mexico and Colorado, including S. jemez sp. nov., S. klomax sp. nov., S. skywalkeri sp. nov., S. speoventus sp. nov., and S. steinmanni sp. nov. Several of the newly described species are single-cave endemics, and our findings suggest that further exploration of western North American cave habitats will likely yield additional new species.

Miocene ostracods from the Tremiti Islands and Hyblean Plateau: biostratigraphy and description of new and poorly known species

The main taxonomic and stratigraphical results of a study of ostracods from the middle-late Miocene of the Tremiti Islands and the Hyblean Plateau are presented. The faunas are mostly typical of deep thermospheric or psychrospheric bathyal environments. Excluding a few, mostly juvenile shallow water contaminants, a total of 127 species were recorded. Twenty-four taxa are discussed herein; of these, 13 species (Cytherella dissimilis nov. sp., Cytherella parvula nov. sp., Cytherella subtilis nov. sp., Argilloecia triangularis nov. sp., Retibythere (Retibythere)? claudii nov. sp., Retibythere (Retibythere)? gibba nov. sp., Cytheropteron (Cytheropteron) joachinoi nov. sp., Cytheropteron (Aversovalva) consuetum nov. sp., Cytheropteron (Aversovalva) trimerumense nov. sp., Cytheropteron (Aversovalva) turgidum nov. sp., Loxoconcha julianii nov. sp., Buntonia whatleyi nov. sp., Pterygocythere nuda nov. sp.) and a subspecies (Costa tricostata dorsoarcuata nov. subsp.) are described as new, while six are left in open nomenclature. The stratigraphical distribution of ostracods is expressed in terms of planktonic foraminiferal zones. Information obtained from this study enriches biostratigraphical data on Mediterranean Miocene deep-sea ostracods, especially with respect to the Langhian.

Novel and known myxobolids (Cnidaria,Myxozoa) infecting Chondrostoma angorense (Cypriniformes: Leuciscidae) in Turkey

Turkey has more than 200 endemic freshwater fish species, one of which is the Ankara nase, Chondrostoma angorense Elvira, 1987 (Cypriniformes: Leuciscidae), a food fish in northern Turkey. Like most endemic fish species in Turkey, its myxosporean parasite fauna (Cnidaria: Myxosporea) are not yet described. We surveyed twenty C. angorense from Lâdik Lake in northern Turkey, and identified two myxosporean parasites from gills of these fish: Myxobolus arrabonensis Cech, Borzák, Molnár, Székely, 2015, and a co-infection of a novel species, Myxobolus polati sp. nov. We characterized both infections based on myxospore morphology, morphometry, tissue tropism, small subunit ribosomal DNA sequence and phylogenetic analysis. Plasmodia of both species were observed in gills, but had distinct tropism: M. arrabonensis is an intrafilamental vascular type, and M. polati sp. nov. is an intralamellar vascular type. We identified M. arrabonensis on the basis of myxospore characters and 100% similarity to the type DNA sequence from the closely-related host C. nasus. The small subunit ribosomal DNA sequence of M. polati sp. nov. (1946 base pairs; GenBank Accession number MH392318) had a maximum similarity of 98% with any Myxobolus sp. from other Eurasian cypriniforms. Phylogenetic analysis revealed that M. polati sp. nov. is most closely related to gill-infecting Myxobolus diversicapsularis from Rutilus rutilus (L.). The present study is the first record of myxosporean species infecting C. angorense comprising a novel species, M. polati sp. nov. and a known species M. arrabonensis.
