The male, female, pupa and larva of Simulium litobranchium n. sp. are described and illustrated. This new species has 12 gill filaments, as do S. duodenicornium Pepinelli, Hamada & Trivinho-Strixino, S. guianense Wise, S. hirtipupa Lutz, S. perplexum Shelley, Maia-Herzog, Lunas Dias & Couch and S. scutistriatum Lutz, but it can be distinguished from these other species by a combination of characters observed at the pupal and adult stages. DNA barcoding showed that Simulium litobranchium n. sp. exhibits more than 4% nucleotide divergence in cytochrome oxidase I from three other closely related species in the Neotropical subgenus S. (Thyrsopelma). The new species was collected in the Brazilian states of Goiás and Minas Gerais and inhabits rivers 30–40 m in width in the Paraná River hydrographic basin. Females were not observed engaging in anthropophilic behavior.

The genus Chilecicada Sanborn, 2014 is shown to be a complex of closely related species rather than a monospecific genus. Chilecicada citatatemporaria Sanborn & Cole n. sp., C. culenesensis Sanborn & Cole n. sp., C. curacaviensis Sanborn & Cole n. sp., C. impartemporaria Sanborn & Cole n. sp., C. magna Sanborn & Cole n. sp., C. mapuchensis Sanborn n. sp., C. oraria Sanborn & Cole n. sp., C. parrajaraorum Sanborn n. sp., C. partemporaria Sanborn & Cole n. sp., C. pehuenchesensis Sanborn & Cole n. sp., C. trifascia Sanborn n. sp., C. trifasciunca Sanborn & Cole n. sp., and C. viridicitata Sanborn & Cole n. sp. are described as new. Chilecicada occidentis Walker, 1850 is re-described to facilitate separation of the new species from the only previously known species. Song and cytochrome oxidase I analysis available for most species support the separation of the new taxa from the type species of the genus. Known species distributions and a key to the species of the genus are also provided. The new species increases the known cicada diversity 61.9% to 34 species, 91.2% of which are endemic to Chile.

Abstract Background The northeastern part of the Qinghai-Tibet Plateau (QTP) presents a high number of plateau loach species. As one of the three major groups of fishes distributed on the QTP, plateau loach has high ecological value. However, the taxonomy and systematics of these fish are still controversial, and a large number of new species have been reported. The reason for this phenomenon is that the degree of morphological variation is low, the phylogenetic information provided by morphological and anatomical features used for species identification is relatively poor, and many cryptic species are observed. Based on the high-density sampling points from the biodiversity hotspots surveyed, this study aims to evaluate the biodiversity of plateau loach in the northeastern part of the QTP and reveal the hidden diversity by comparing morphological species with molecular operational taxonomic units (MOTUs). Results After careful identification and comparison of the morphology and DNA barcoding of 1630 specimens, 22 species were identified, with 20 considered valid local species and two identified as new species that had not been previously described. Based on the combination of morphological and molecular methods, a total of 24 native species were found, two of which were cryptic species: Triplophysa robusta sp1 and Triplophysa minxianensis sp1. Fourteen of the 24 species form clusters of barcodes that allow them to be reliably identified. The remaining cases involved 10 closely related species, including rapidly differentiated species and species that seemed to have experienced incomplete lineage sorting or showed introgressions. Conclusions The results highlight the need to combine traditional taxonomies with molecular methods to correctly identify species, especially closely related species, such as the plateau loach. This study provides a basis for protecting the biodiversity of plateau loach.

A New Species

Deutonura gibbosa, a new species of the phlegraea group, is described. It is characterized by a large elongate uneven tubercle Di on Abd. V, with chaetae Di1 and Di2 shift backward. It has otherwise the same chaetotaxic pattern as the subspecies sylvatica of D. deficiens. Deutonura gibbosa sp. nov. is the most widespread Deutonura in the Alps and southern Jura. Its barcode sequence is provided and compared to those of four other Deutonura of the phlegraea group; it unambiguously differs from them, including from D. deficiens sylvatica, its closest relative according to current taxonomy. This is the most convincing example so far that barcode may help to discriminate taxa among closely related species in Collembola.

Qinghai Tibet Plateau

Abstract Background: The northeastern part of the Qinghai-Tibet Plateau (QTP) is one of the areas where the number of species of plateau loach is the largest. As one of the three major groups of fishes distributed on the QTP, plateau loach have very important ecological value. However, their taxonomy and systematics are still controversial, and a large number of new species have been reported. The reason for this phenomenon is that the degree of morphological variation is low, the phylogenetic information provided by morphological and anatomical features used for species identification is relatively poor, and there are many cryptic species. Based on the high-density sampling points from the biodiversity hotspots surveyed, this study aims to evaluate the taxonomic characteristics of the plateau loach by means of morphology, DNA barcoding and multiple species demarcation methods to accurately describe species and allocate taxonomic units to unknown specimens. Results: After careful identification and comparison of the morphology and DNA barcoding of 1,630 specimens, 22 species were identified, 20 of which were considered valid local species and two of which were new species that had not been described. Based on the combination of morphological and molecular methods, a total of 24 native species have been found, two of which are cryptic species: Triplophysa robusta sp1 and Triplophysa minxianensis sp1. Fourteen of the 24 species form clusters of barcodes, which allow them to be reliably identified. The remaining cases involved 10 closely related species, some of which were rapidly differentiated, had a disputed taxonomic status, or showed introgressions.Conclusions: The results highlight the need to combine traditional taxonomies with molecular methods to correctly identify species, especially in closely related species such as the plateau loach. This study provides a basis for protecting the biodiversity of plateau loach.

A New Species

A new species of Protaphorura Absolon, 1901 (Collembola, Onychiuridae), P. cykini sp.nov., is described from a cold karst cave in the Irkutsk region, Siberia, Russia. It is an obligate cave species with the largest body size (4.3–5.6 mm) of all congeners. The species is further characteristic by the pseudocellar formula as 3(2)2/022/33343, high number of vesicles in postantennal organ (65–71) and subapical organite protected with two papillae. A partial sequence of cytochrome oxidase I (COI DNA barcoding marker) gene is used to verify the taxonomic status of the new species and the barcode sequence is compared with other congeners available in GenBank database. Distribution and diversity of cave Collembola of Siberia is discussed.

Pimpinella ibradiensis, an unusual new species found in the Toka Yayla (İbradı, Antalya) in southern Anatolia, is described and illustrated. Site conditions, synecology and conservation status of P. ibradiensis are considered. In light of the comparison with the other closely related four species, namely P. nephrophylla, P. flabellifolia, P. sintenisii and P. paucidentata, its similarity within the genus are discussed. P. ibradiensis is easly distinguished from its relatives by its white petals, presence of bracts and bracteoles, larger fruits (4–5.5 × 1–2 mm), and having serrulate basal leaves with 60–95 strongly cartilaginous teeth along margins. The geographical distribution of P. ibradiensis and closely related species are mapped and the identification key of those species is updated.
