Lodevoisadia coheni gen. et sp. nov. is described as the ninth species of ‘Grylloblattodea’ from the middle Permian of the Salagou Formation, near Lodève town (France). It is currently not reasonable to place this species into a specific family, even though it seems to share most characters with the small family Tunguskapteridae. The lack of phylogenetic analysis and the current poor delineation of the majority of the grylloblattodean families (lacking synapomorphies) render any attribution of new taxa to a particular family often uncertain.
Elusive flaws are identified in techniques widely adopted to organize the Material Examined sections in taxonomic publications, mostly regarding the usage of the term ibidem and the nesting of information such as country and states. Logical errors are identified that prevent objective retrieval of the original information and can hinder or block its interpretation, even in case-by-case analyses. It is demonstrated that the free usage of ibidem in the sense of “same as previous except as follows” compromises the interpretation of data, characterizing bad practice. Solutions are proposed for the precise usage of both the term ibidem and the nesting technique. A new technique for organizing, compressing, and presenting information, called grid-setting, is described and evaluated. Its most notable practical effect is that the Material Examined section becomes literally a coded data sheet, which can be accurately converted back to spreadsheet format. In addition, the grid-setting technique was able to generate texts up to 30% shorter than those edited with the best-known traditional techniques. The new ideas and fixes are incorporated into a new software, flexible enough to process varied and unlimited data into largely user-defined texts, which remain nevertheless universal in their format and logical interpretation.
Metopiinae is a relatively large subfamily of Darwin wasps with a cosmopolitan distribution. Species of this subfamily can be distinguished by a convex, and mostly undivided face and clypeus. Among 113 species in 24 genera of the Oriental region, only 24 species in eight genera are reported from India. Here, we describe and illustrate a new genus, Soliga, based on collections made from the Western Ghats and Eastern Himalayas, two important biodiversity hotspots. The combination of absence of epicnemial carina on dorsolateral part of mesopleuron, absence of propodeal carinae and dorsal carinae of first metasomal tergite differentiates the new genus from other metopiine genera. An illustrated key to the Indo-Australian metopiine genera is provided along with comments on new generic placement and character variability of metopiines.
Gloydius is a widespread pitviper group occurring from Eastern Europe to Korea and Siberia, with only one known species, G. himalayanus (Günther, 1864), found south of the Himalayas. We provide combined genetic and morphological data for G. himalayanus from specimens collected from Himachal Pradesh, India. Bayesian Inference and Maximum Likelihood phylogenetic analysis were performed on four concatenated mitochondrial genes, along with a multi-locus coalescent analysis of these and five additional nuclear genes. Our results indicate that G. himalayanus from the Chamba Valley, in western Himachal Pradesh, are highly distinct from the remaining studied populations. Haplotype networks of each nuclear locus showed that G. himalayanus contains high haplotype diversity with low haplotype sharing between the Chamba Valley population and populations from further west. Principal component analysis and canonical variate analysis conducted on morphological data of live and museum specimens also highlight the morphological distinctiveness of the Chamba population and we herein describe this population as a new species, Gloydius chambensis sp. nov. Recent descriptions of other new species of snakes from this valley underscores its isolation and suggests that further herpetological investigation of the highly dissected landscapes of the western Himalayas is needed to assess the true diversity of the region.
During a recent investigation of ant-mimicking arthropods in Costa Rica, two new species of salticid spiders were discovered. Here, I provide descriptions of the two species, Myrmapana costaricaensis sp. nov. and Corcovetella galianoae sp. nov. The former species has two forms; the dark form resembles Neoponera ants, while the light form resembles Pseudomyrmex ants. Corcovetella galianoae resembles Camponotus ants.
This study presents the inventory of sea spiders (Pycnogonida) sampled during the Madibenthos Expedition in Martinique (West Indies). Species were discriminated leaning on morphological and molecular data. A total of 761 specimens are classified in 72 species, 16 genera and nine families. Thirteen new species are described: Ammothella dirbergi sp. nov., A. krappi sp. nov., Tanystylum boucheti sp. nov., T. ingrallis sp. nov., Ascorhynchus iguanarum sp. nov., Eurycyde kaiouti sp. nov., Nymphon dorlis sp. nov., N. ludovici sp. nov., N. martinicum sp. nov., N. timons sp. nov., Anoplodactylus madibenthos sp. nov., Pycnogonum cesairei sp. nov. and Rhynchothorax sidereus sp. nov. We describe a neotype for Anoplodactylus micros Bourdillon, 1955 from the type locality. Martinique now includes 79 species of sea spiders, mostly endemic to the Tropical Northwestern Atlantic, cosmopolitan or shared with the South America Atlantic coast. Some species are potentially introduced. However, our knowledge of the distribution of species found in Martinique is probably biased by the scarcity of diagnostic morphological characters. Also, nine potentially cryptic species (discriminated on genetic data alone), are identified, shedding light on the overlooked diversity of sea spiders in the Tropical Northwestern Atlantic. Therefore, we call for a more widespread use of barcoding in sea spiders.
The genus Andromma Simon, 1893 is revised. The type species A. aethiopicum Simon, 1893 (♂♀) and the other three known species, A. anochetorum Simon, 1909 (♂), A. bouvieri Fage, 1936 (♀) and A. raffrayi Simon, 1899 (♂♀), are redescribed. The types of the subspecies A. raffrayi inhacorense Lessert, 1936 were not examined. This subspecies is considered a synonym of the nominal species. Nineteen new species are described and illustrated: A. albinovani sp. nov. (♂♀), A. alvoculatum sp. nov. (♀), A. anacardium sp. nov. (♀), A. cyamos sp. nov. (♀), A. cycnotrachelos sp. nov. (♂♀), A. delphiurum sp. nov. (♂♀), A. deogratias sp. nov. (♂♀), A. dicranobelos sp. nov. (♂), A. didrepanum sp. nov. (♂), A. divinagraciae sp. nov. (♂♀), A. elephantactes sp. nov. (♀), A. ghesquierei sp. nov. (♂♀), A. heligmos sp. nov. (♀), A. helix sp. nov. (♀), A. juakalyi sp. nov. (♂), A. katangensis sp. nov. (♀), A. ophiophagum sp. nov. (♀), A. prosopion sp. nov. (♀) and A. velum sp. nov. (♂♀). The distribution of the species and their apparent commensalism with termites are discussed.
This paper describes new or little known Amphipoda collected from Hydrozoa, Bryozoa, Porifera or kelp along the Chilean fjord region. The following species have been found and most of them were redescribed and illustrated: Sunamphitoe femorata (Krøyer, 1845); Caprella cf. equilibra Say, 1818; Haplocheira barbimana robusta K.H. Barnard, 1932; Epimeria (Metepimeria) acanthurus (Schellenberg, 1931); Labriphimedia vespuccii K.H. Barnard, 1931; Leucothoe kawesqari Esquete & Aldea, 2015; Podocerus cf. danae (Stebbing, 1888); Ligulodactylus macrocheir (Schellenberg, 1926) and Torometopa cf. crassicornis (Schellenberg, 1931). One species in this contribution is new to science: Liouvillea rocagloria sp. nov.
Juga is a genus of freshwater snails distributed from northern Washington to central California. The taxonomy and classification of the genus has a long and complex history, driven mainly by the features of their highly variable shells. The number of recognized species has fluctuated from ~9 to 11; however, it has been claimed that the actual diversity may be three times that number. We here present a systematic revision using a recently published molecular phylogeny as a framework, which supported the interpretation that there are only nine valid species. Comprehensive review of type material and original descriptions for all available species-group names indicates that almost all species previously considered valid were para- or polyphyletic grades of organization in shell morphology. Most species previously suggested to be putatively new were confirmed to be morphological variants of species already described. Species accounts include complete synonymies and partial chresonymies; the shells and radulae are illustrated and described. Lectotypes are designated for Melania plicifera Lea, 1838, M. silicula Gould, 1847, and M. rudens Reeve, 1860. Three species, Juga caerulea sp. nov., J. canella sp. nov., and J. douglasi sp. nov., are described as new and one species is excluded from the genus. The subgenera Calibasis D.W. Taylor, 1966 and Idabasis D.W. Taylor, 1966 are synonymized with Juga.
Using an integrative approach (morphology of the adult and larvae, bioacoustics, osteology, karyotype, and molecular data), we described a new tetraploid species of Odontophrynus to the Mantiqueira mountain range, in southeastern Brazil. The data suggest that Odontophrynus toledoi sp. nov., O. juquinha and Odontophrynus sp. (aff. juquinha) comprise a clade with specimens distributed along three distinct mountain ranges in Brazil: Mantiqueira (O. toledoi sp. nov.) and Espinhaço (O. juquinha) mountains, both in southeastern Brazil, and Diamantina Plateau (O. aff. juquinha), in northeastern Brazil. The new species is morphologically similar and closely related to O. juquinha, but is distinguished in morphology (both adult and larval), karyotype (O. toledoi sp. nov. is tetraploid and O. juquinha is diploid), and corroborated by phylogenetic inferences. We also show that these species do not exchange haplotypes in the 16s gene. Furthermore, although the raw acoustic parameters of Odontophrynus toledoi sp. nov. and O. juquinha overlap at the limits of their ranges, we found a clear difference in the acoustic space structure.
