This review covers Parageron Paramonov s. lat., including 36 species. Three new genera are proposed: Ectopusia gen. nov., Protypusia gen. nov. and Parusia gen. nov.; Parageron s. str. more narrowly defined. Eleven new species are described: Parageron longilingua sp. nov., Protypusia argentata gen. et sp. nov., Pro. separata Gibbs & Theodor gen. et sp. nov., Pro. flavipalpis gen. et sp. nov., Pro. kerkini gen. et sp. nov., Pro. strymonas gen. et sp. nov., Parusia almeria gen. et sp. nov., Pru. benoisti gen. et sp. nov., Pru. cyrenaica gen. et sp. nov., Pru. faesae gen. et sp. nov. and Pru. propinqua gen. et sp. nov. Two species raised from synonymy Par. orientalis Paramonov stat. rev. and Pru. taeniolata (Costa) stat. rev. Two species synonymised Pro. major Macquart syn. nov. and Usia arida Báez syn. nov. Eight species removed from Usiini to Apolysini, Apolysis bicolor (Efflatoun) comb. nov., A. elbae (Efflatoun) comb. nov., A. flavipes (Efflatoun) comb. nov., A. marginata (Brunetti) comb. nov., A. minuscula (Efflatoun) comb. nov., A. parvula (Efflatoun) comb. nov., A. turkmenica (Paramonov) comb. nov. and A. volkovitshi (Zaitzev) comb. nov. Apolysis melanderi Gibbs nom. nov. replaces A. bicolor (Melander) (was in Oligodranes) and A. hessei Gibbs nom. nov. replaces A. minuscula Hesse. Two neotypes and nine lectotypes are designated.
We present an updated, subjective list of the extant, non-marine ostracod genera and species of the world, with their distributions in the major zoogeographical regions, as well as a list of the genera in their present hierarchical taxonomic positions. The list includes all taxa described and taxonomic alterations made up to 1 July 2018. Taxonomic changes include 17 new combinations, 5 new names, 1 emended specific name and 11 new synonymies (1 tribe, 4 genera, 6 species). Taking into account the recognized synonymies, there are presently 2330 subjective species of non-marine ostracods in 270 genera. The most diverse family in non-marine habitats is the Cyprididae, comprising 43.2% of all species, followed by the Candonidae (29.0%), Entocytheridae (9.1%) and the Limnocytheridae (7.0%). An additional 13 families comprise the remaining 11.8% of described species. The Palaearctic zoogeographical region has the greatest number of described species (799), followed by the Afrotropical region with 453 species and the Nearctic region with 439 species. The Australasian and Neotropical regions each have 328 and 333 recorded species, respectively, while the Oriental region has 271. The vast majority of non-marine ostracods (89.8%) are endemic to one zoogeographical region, while only six species are found in six or more regions. We also present an additional list with 'uncertain species', which have neither been redescribed nor re-assessed since 1912, and which are excluded from the main list; a list of taxonomic changes presented in the present paper; a table with the number of species and % per family; and a table with numbers of new species described in the 20-year period between 1998 and 2017 per zoogeographical region. Two figures visualize the total number of species and endemic species per zoogeographical region, and the numbers of new species descriptions per decade for all families and the three largest families since 1770, respectively.
Erebaces woodruffi Anderson, new species (Curculionidae: Molytinae: Cryptorhynchini), from Palawan (Philippines) is described and illustrated. This is the second species of the genus Erebaces Pascoe described from the Philippines. It can be separated from Erebaces kidapawanus Pancini by the pair of divergent dorsal pale-scaled lines on the pronotum extended onto the elytra and by the form of the elytral tubercles.
The concept of the jumping spider genus Pochytoides Berland & Millot, 1941 is reviewed, based on the examination of described and undescribed species. Pochytoides is elevated from the subgeneric to the generic rank and a short diagnosis and description of the genus are presented. Redescriptions or descriptions of all species are provided together with a key to the species. Two new combinations are proposed: Pochytoides perezi (Berland & Millot, 1941) comb. nov. and P. poissoni (Berland & Millot, 1941) comb. nov. (both from Pochyta). Pochyta remyi Berland & Millot, 1941 originally placed in the subgenus Pochytoides is excluded; new combination Thiratoscirtus remyi (Berland & Millot, 1941) comb. nov. is proposed for it (but its generic status is uncertain). Six new species are described: Pochytoides monticola sp. nov., P. obstipa sp. nov., P. lamottei sp. nov., P. patellaris sp. nov., P. securis sp. nov. and P. spiniger sp. nov. The genus has a West African distribution.
The Bittacidae fauna in Guizhou Province, China is reviewed. Eleven species in the genera Terrobittacus Tan & Hua, 2009 and Bittacus Latreille, 1805 of Bittacidae are documented in Guizhou, including three new species: Bittacus dilobus sp. nov. and Bittacus leigongshanicus sp. nov. from Leigongshan, and Bittacus multisetus sp. nov. from Yushe. A key to species of Bittacidae in Guizhou is provided.
Australia is predicted to have a high number of currently undescribed ostracod taxa. The genus Bennelongia De Deckker & McKenzie, 1981 (Crustacea, Ostracoda) occurs in Australia and New Zealand, and has recently shown potential for high speciosity, after the description of nine new species from Western Australia. Here, we focus on Bennelongia from eastern Australia, with the objectives of exploring likely habitats for undiscovered species, genetically characterising published morphological species and scanning classical species for cryptic diversity. Two traditional (morphological) species are confi rmed to be valid using molecular evidence (B. harpago De Deckker & McKenzie, 1981 and B. pinpi De Deckker, 1981), while three new species are described using both morphological and molecular evidence. Two of the new species belong to the B. barangaroo lineage (B. dedeckkeri sp. nov. and B. mckenziei sp. nov.), while the third is a member of the B. nimala lineage (B. regina sp. nov.). Another species was found to be genetically distinct, but is not formally described here owing to a lack of distinguishing morphological features from the existing species B. cuensis Martens et al., 2012. Trends in diversity and radiation of the genus are discussed, as well as implications these results have for the conservation of temporary pool microfauna and our understanding of Bennelongia’s evolutionary origin.
Harpactea dufouri (Thorell, 1873) was collected in the Gavarres protected natural area in Catalonia, Spain. The specimens were compared with specimens from Mallorca, Balearic Islands,
and found to be conspecific. The female of the species is described here for the first time. The new finding proves that Harpactea dufouri occurs outside the Balearic Islands. The species, however, may be endemic to Catalonia.
It is widely acknowledged that biodiversity change is affecting human well-being by altering the supply of Nature's Contributions to People (NCP). Nevertheless, the role of individual species in this relationship remains obscure. In this article, we present a framework that combines the cascade model from ecosystem services research with network theory from community ecology. This allows us to quantitatively link NCP demanded by people to the networks of interacting species that underpin them. We show that this “network cascade” framework can reveal the number, identity and importance of the individual species that drive NCP and of the environmental conditions that support them. This information is highly valuable in demonstrating the importance of biodiversity in supporting human well-being and can help inform the management of biodiversity in social-ecological systems.
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.
