Contributions to the fauna and systematics of the Stenopelmatoidea (Orthoptera) of Indochina and some other territories: VIII

Material on the Indo-Malayan Gryllacridinae (Stenopelmatidae) of the genera Zalarnaca Gor., Dinolarnaca gen. n., Phryganogryllacris Karny, Neanias Br.-W., and Aancistroger B.-Bien. is considered. A new genus, a new subgenus, 17 new species, and 2 new subspecies are described. Some insufficiently known taxa are redescribed. Systematic position of several species and subspecies is clarified.     

To the knowledge of the leaf beetle genus Cystocnemis (Coleoptera, Chrysomelidae)

Four subspecies of Cystocnemis discoidea are distinguished; two subspecies are described as new to science based on investigation of intraspecific variation in different parts of the species range, and ssp. gebleri was resurrected from synonymy. The ways of speciation in highland-hollow landscapes are discussed. The alpine subspecies C. discoidea oreas ssp. n. has an altibiome disjunction with the nominotypical subspecies. Similarity of the alpine subspecies of C. discoidea to the species from the subgenus Entomomela was found to be the reason of permanent confusion of representatives of these taxa. The subgenus Entomomela is transferred from the genus Oreomela to the genus Cystocnemis. A key to species and subspecies of the genus Cystocnemis is given.     

A new form of <Emphasis Type="Italic">Kailasius autocrator</Emphasis> (Lepidoptera,Papilionidae) from the eastern Pamirs

A new subspecies, Kailasius autocrator pshartanus, from the eastern Pamirs (the Muzkol Ridge, Sasyk River) is described. The new subspecies is distinguished from the nominative subspecies by the wing pattern and ecology. This subspecies has the most primitive wing pattern in the genus. The range of this species is considered to be the center of Kailasius genus origin.     

Contribution to the fauna and systematics of the stenopelmatoidea (Orthoptera) of Indochina and some other territories: IX

The material of the Indo-Malayan and Papuan Rhaphidophorinae (Rhaphidophoridae) of the genera Eurhaphidophora Gor., Minirhaphidophora Gor., Stonychophora Karny, and Neorhaphidophora Gor. is considered. 21 new species and a previously unknown male of Minirhaphidophora are described. Rhaphidophora foeda Br.-W. is transferred to Stonychophora; Rh. sumatrana Zacher is removed from Stonychophora and from the synonyms of S. crenulata (Br.-W.); S. tatiana falsa Gor. is treated as a separate species. New data on the composition of the genera studied, the diagnostic characters of these genera and some species previously described, and data on the distribution of some species are given.     

Le genre Postepithyris makridin (térébratulidés,brachiopodes) dans l'oxfordien et le kimméridgien Français

The questions relating to the type-species of genus PostepithyrisMakridin and to its systematic position within Terebratulids are discussed.The French species are described: besides the type-species P. cincta (Cotteau) from Upper Oxfordian, two species from Inferior Kimmeridgian can be included in this genus: P. minor (Douvillé) and P. dubisensis nov. sp.A new subspecies P. cincta mosensis nov., recently discovered in Oxfordian from East of the Paris Basin, can also be assigned to the genus.Postepithyris did not evolve through a single special facies: the species could supported different environmental conditions.     

A review of the chrysomelid genus <Emphasis Type="Italic">Hyperaxis</Emphasis> Gemm. et Har., 1874 (Coleoptera,Chrysomelidae: Eumolpinae) from Vietnam

A review of species of the genus Hyperaxis Gemminger et Harold from Vietnam is given. Five new species (H. dentifemur sp. n., H. longipilosa sp. n., H. sonlanga sp. n., H. phanrangi sp. n. and H. buonloica sp. n.) and a new subspecies (H. buonloica darlaki subsp. n.) are described. A key to all the 11 species of the Vietnamese fauna is given. The genitalia are figured for all species. Lectotype is designated for Hyperaxis pallidipes Pic.     

A new species and a new subspecies of the stargazer genusGnathagnus from Northwestern Australia

Heretofore the genusGnathagnus (Uranoscopidae) has been composed of three species:G. elongatus (Temminck et Schlegel) from northern Australia to Japan,G. innotabilis (Waite) from Australasia, andG. egregius (Jordan et Thompson) from the western Atlantic Ocean. In this paper, a new species and a new subspecies from northwestern Australia are described and a key to the known species and subspecies of the genus is presented.     

An evaluation of the species and subspecies of the genus Salmonella with whole genome sequence data: Proposal of type strains and epithets for novel S. enterica subspecies VII,VIII, IX,X and XI

Species and subspecies within the Salmonella genus have been defined for public health purposes by biochemical properties; however, reference laboratories have increasingly adopted sequence-based, and especially whole genome sequence (WGS), methods for surveillance and routine identification. This leads to potential disparities in subspecies definitions, routine typing, and the ability to detect novel subspecies. A large-scale analysis of WGS data from the routine sequencing of clinical isolates was employed to define and characterise Salmonella subspecies population structure, demonstrating that the Salmonella species and subspecies were genetically distinct, including those previously identified through phylogenetic approaches, namely: S. enterica subspecies londinensis (VII), subspecies brasiliensis (VIII), subspecies hibernicus (IX) and subspecies essexiensis (X). The analysis also identified an additional novel subspecies, reptilium (XI). Further, these analyses indicated that S. enterica subspecies arizonae (IIIa) isolates were divergent from the other S. enterica subspecies, which clustered together and, on the basis of ANI analysis, subspecies IIIa was sufficiently distinct to be classified as a separate species, S. arizonae. Multiple phylogenetic and statistical approaches generated congruent results, suggesting that the proposed species and subspecies structure was sufficiently biologically robust for routine application. Biochemical analyses demonstrated that not all subspecies were distinguishable by these means and that biochemical approaches did not capture the genomic diversity of the genus. We recommend the adoption of standardised genomic definitions of species and subspecies and a genome sequence-based approach to routine typing for the identification and definition of novel subspecies.     

Revision of the genus Parasapyga Turner (Hymenoptera,Sapygidae), with the description of two new species

Two new species, Parasapyga boschi sp. n. from Vietnam and P. yvonnae sp. n. from Indonesia are described. Parasapyga walshae van der Vecht, 1940, is treated as a valid species instead of a subspecies of P. moelleri Turner, 1910. A key to the species of the genus is added and all species are illustrated.     

The More We Search,the More We Find: Discovery of a New Lineage and a New Species Complex in the Genus Asparagopsis

In the past few decades, in the marine realm in particular, the use of molecular tools has led to the discovery of hidden taxonomic diversity, revealing complexes of sister species. A good example is the red algal genus Asparagopsis. The two species (A. armata and A. taxiformis) recognized in this genus have been introduced in many places around the world. Within the nominal species A. taxiformis, previous molecular analyses have uncovered several lineages, suggesting the existence of sister species or subspecies. Although the genus has been well studied in some regions (e.g., the Mediterranean Sea and Hawaii), it remains poorly investigated in others (e.g., South Pacific). Our study mainly focused on these latter areas to clarify lineages and better determine lineage status (i.e., native vs. introduced). A total of 188 specimens were collected from 61 sites, 58 of which had never been sampled before. We sequenced the DNA from samples for three markers and obtained 112 sequences for the chloroplastic RuBisCo spacer, 118 sequences for the nuclear LSU rRNA gene, and 174 for the mitochondrial spacer cox2-3. Phylogenetic analyses using all three markers suggested the existence of two cryptic sister species with the discovery of a new clade within A. armata. This clade was found only in Western Australia, Tasmania and New Zealand, and is thus restricted to a subregional biogeographic unit. We also discovered a new, fifth lineage for A. taxiformis restricted to the South Pacific and Western Australia. Except for this newly described lineage, all other lineages showed a global distribution influenced by introduction events. These results illustrate the difficulty in accurately defining cosmopolitan species. Our findings also highlight the need for targeted (i.e., in poorly studied areas) and geographically extensive sampling efforts when studying taxa that have been introduced globally and that are likely to hide species complexes.     

<Emphasis Type="Italic">Kailasius autocrator</Emphasis> (Avinov, 1913) (Lepidoptera,Papilionidae) found in the alai mountain ridge (the Pamir-Alai)

A new subspecies, Kailasius autocrator murun Korb, ssp. n., of the species Kailasius autocrator (Avinov, 1913) from the eastern part of the Alai Mountain Ridge is described. This subspecies differs from the other known ones in the smaller size (the fore-wing length is less than 23 mm) and in the presence of 5 black rounded spots in the submarginal area of the hind-wing upper side (4 spots in the nominotypical subspecies and K. a. pshartanus). The new subspecies is shown to be the most archaic one among the subspecies of the genus Kailasius by the wing pattern. Possible ways for the origin of local and small populations of morphologically different subspecies of the genus 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.     

Contributions to the fauna and systematics of Stenopelmatoidea (Orthoptera) of Indochina and some other territories: VII

Data on the genera Gryllacris A.-Serv., Aphanogryllacris Karny, and Papuogryllacris Griff. (Stenopelmatidae, Gryllacridinae) from the Indo-Malayan and Papuan Regions are reported. The former genera Gigantogryllacris Karny and Pardogryllacris Karny are tentatively included in the genus Gryllacris as subgenera. Eight new species and three new subspecies are described. Neotype of Gryllacris signifera (Stoll) and lectotypes of G. obscura Br.-W., G. obscura sumatrana Griff., G. javanica (Griff.), G. appendiculata Br.-W., G. fuscifrons Gerst., G. sirambeica battaka (Griff.), G. excelsa Br.-W., G. heros Gerst., and Aphanogryllacris sexpunctata Br.-W. are designated. G. athleta Br.-W., G. adjutrix Br.-W., and, probably, Aphanogryllacris sexpunctata obscuriceps Karny are considered to be distinct species. Some insufficiently known taxa are redescribed, the systematic position of several species and subspecies is clarified, and new distributional data are reported.     

Definition and review of the lancangjiang species group of the termitophilous genus Orthogonius Macleay, 1825 (Coleoptera,Carabidae, Orthogoniini)

The lancanjiang species group of the termitophilous ground beetle genus Orthogonius Macleay, 1825, is defined and reviewed. This group is characterized by the black and rather elongate body, dense punctation on head and elytra, long and slender appendages, thin fore tibiae, and elytral interval 3 without a subapical setiferous pore. To date, the lancanjiang species group is composed of four species and one subspecies, including three new species and one new subspecies which are described in the present paper: O. macrophthalmus sp. n. (northern Vietnam), O. euthyphallus sp. n. (southern Vietnam), O. euthyphallus bolavenensis ssp. n. (southern Laos) and O. carinatus sp. n. (northern Laos). A distribution map and a key to all species of this group are also provided.     

Early carboniferous bryozoans from the Kodinka section, Middle Urals

An assemblage of Viséan-Serpukhovian bryozoans from the vicinity of the village of Kodinka (Sverdlovsk Region, Middle Urals) is studied for the first time. This assemblage is represented by two new species, Primorella kodinkensis sp. nov. and Heloclema uralicum sp. nov.; already known species Heloclema magnificum Gor. and Nikiforopora concentrica (Nikif.); and three morphotypes Fistulamina sp., Penniretepora sp., and Polyporella sp. Some specific features in the distribution of bryozoans of the Middle Urals at the beginning of the Carboniferous are discussed.     

The Villafranchian perissodactyls of Italy: knowledge of the fossil record and future research perspectives

The Villafranchian fossil record of Perissodactyla is of a great interest because the appearance of the genus Equus and disappearance of the genus Tapirus mark important faunal turnovers. Here, we provide new data on Italian Villafranchian Tapiridae, Rhinocerotidae, and Equidae with updates from the last comprehensive review; most relevant are those of the Rhinocerotidae and Equidae. At present only two Villafranchian rhinoceros’ species are documented in Italy: Stephanorhinus jeanvireti and Stephanorhinus etruscus. The two species can be distinguished by several morphological features and by the dimensions of their bones. Stephanorhinus etruscus occurred throughout the Villafranchian; despite the numerous records, its remains are not enough to investigate morphometric trends. The Equidae include seven species including new occurrences of Hipparionine horses and of the genus Equus. The statistical analyses performed on the Equus species show two different evolutionary trends, namely the stenonine lineage “Equus livenzovensis - Equus stenonis” and the small-to-medium-sized lineage “Equus senenzensis - Equus stehlini”, suggesting a different evolution of these species. Moreover, the analyses show close relationships between the Italian Equus stenonis samples and three European Equus stenonis subspecies (E. stenonis vireti, E. stenonis guthi, and E. stenonis pueblensis). We begin to reconsider the validity of E. stenonis subspecies identification in order to provide new perspectives on the taxonomy of this species.
