Recent integrative investigations of the terrestrial ellobiid genus, Zospeum, have revealed significant findings concerning its Alpine-Dinaric evolution and taxonomy. Due to the expected discrepancy between the useful, but limited, 1970s’ classification system based on shell data and the results of recent genetic analyses in the latest investigation, a revision of the entire radiation was undertaken, and a new classification system was devised by the present authors in an earlier paper. Concurrent to this work, molecular sequences from two Austrian caves were published independently of our revision by another research group. By incorporating these genetic data within our phylogenetic framework here, we show that the Austrian individuals are genetically most similar to Zospeum amoenum and consequently, classify them within that species. We additionally reveal two new genetic lineages from the largely under-sampled southern extension of Zospeum’s known distributional range. The first lineage, deriving from the region of Dubrovnik, Croatia, is a potential candidate for genetically clarifying Zospeum troglobalcanicum. The second lineage derives from the municipality of Tomislavgrad, Bosnia-Herzegovina and is herein, described a new species: Zospeum simplex Inäbnit, Jochum & Neubert, sp. nov.

A New Species

Sphaerotheca pashchima, a new species of burrowing frog, is described from western India. It can be diagnosed from all its congeners based on a combination of characters including interorbital width less than upper eyelid width, snout to nostril distance less than half of eye diameter, nostril nearer to snout than to eye, internarial distance greater than inter orbital distance, snout rounded, dorsum rough and warty, finger 2 length equal to or less than finger 4 length, finger 1 less finger 3 length, outer metatarsal tubercle absent, tibio tarsal tubercle absent, length of inner metatarsal tubercle more than three times the inner toe length and reduced webbing.  We also provide 16S rRNA gene sequence for S. pashchima sp. nov. and show that it is genetically distinct from species of Sphaerotheca for which genetic data is available.

A New Species

We describe a new species of drongo in the Square-tailed Drongo (Dicrurus ludwigii) complex using a combination of biometric and genetic data. The new species differs from previously described taxa in the Square-tailed Drongo complex by possessing a significantly heavier bill and via substantial genetic divergence (6.7%) from its sister-species D. sharpei. The new species is distributed across the gallery forests of coastal Guinea, extending to the Niger and Benue Rivers of Nigeria. We suspect that this taxon was overlooked by previous avian systematists because they either lacked comparative material from western Africa or because the key diagnostic morphological character (bill characteristics) was not measured. We provide an updated taxonomy of the Square-tailed Drongo species complex.

AbstractAmong fish parasitic nematodesRhabdochonais one of the most speciose genera, withc.100 species. Twelve congeneric species occur in Mexican freshwater fishes, in a region located between the Nearctic and Neotropical biogeographical regions. Host association and biogeographical history have determined the high species richness ofRhabdochonain Mexico. One of these species,Rhabdochona mexicana, is highly specific to the characid genusAstyanax.Characids are a group of freshwater fish with Neotropical affinity. In this paper, we explore the genetic diversity ofR. mexicanathrough samples obtained from populations ofAstyanaxspp. across river basins of Mexico and Guatemala. Sequences of one mitochondrial and two ribosomal genes were obtained from 38 individuals and analysed using Maximum Likelihood and Bayesian Inference analysis. Phylogenetic analyses usingcox1, and a concatenated alignment of 18S + 28S +cox1 recovered two genetic lineages. One of them corresponded withR. mexicana sensu stricto; this lineage included three reciprocally monophyletic subgroups; the other lineage was highly divergent and represented a putative candidate species. A detailed morphological study was conducted to corroborate the molecular findings. We describe a new species herein and discuss the implications of using molecular tools to increase our knowledge about the diversity of a speciose genus such asRhabdochona.

DNA barcoding of stygobiotic shrimps of the genus Xiphocaridinella Sadowsky, 1930 (Crustacea: Decapoda: Atyidae) collected in underground streams flowing inside two neighboring large karst caves (Otap and Abrskil сaves) revealed the presence of two distinct genetic lineages representing the first case of species co-occurrence in the Western Caucasus. The paper presents the complete morphological re-description of stygobiotic atyid shrimp Xiphocaridinella ablaskiri (Birštein, 1939) and the description of a new species using genetic and morphological analysis. Other known cases of co-occurrence of several stygobiotic shrimp species in the same cave system as well as new genetic data (COI mtDNA) on Western Caucasian species of the genus Xiphocaridinella are discussed in the paper.

Geographically Isolated

Based on a combination of morphological and genetic data, geographically isolated populations of Pygopus from northeastern Queensland, formerly referred to Pygopus lepidopodus (Lacépède), are herein described as a new species. Pygopus robertsi sp. nov. can be diagnosed from its congeners by a suite of scalation characters, including fewer keeled dorsal scales, presence of a single continuous row of supracilaries and a lower number of midbody scale rows. It is also deeply divergent genetically from samples of Pygopus lepidopodus from southern Australia. The known distribution of Pygopus robertsi sp. nov. is similar to that of a number of taxa centred upon relatively dry ecotonal habitats at the western edge of the rainforest blocks of north-eastern Queensland. Additional samples and systematic work will be required to examine the evolutionary divergence of apparently isolated populations of the new species, and the significance of considerable genetic and morphological diversity within remaining populations of Pygopus lepidopodus from south-eastern and southern Australia.

A New Species

Among the Anatolian Tettigoniinae (Orthoptera, Tettigoniidae) the genera Anterastes, Koroglus, Sureyaella and Rhacocleis are distinguishable from the others by presence of one pair of spurs on the apico-ventral end of hind tibiae. The last two can be easily distinguished from the others by several distinct features, but the separation of the first two from each other is problematic. A new species described here provided opportunity of re-evaluating their taxonomy. The new species Anterastes antecessor sp. n. is described based on morphology, male calling song and genetic data. The taxonomy of Anterastes and Koroglus is rectified based on phylogentic hypotheses obtained from representative 16S rDNA haplotypes. Sureyaella bella, Parapholidoptera signata and Bolua turkiyae are used as out groups in different combinations to obtain a more stable phylogeny. Although analyses with different outgroups suggested the same topology, the phylogenetic tree with outgroups Parapholidoptera signata and Bolua turkiyae resulted with the highest bootstrap supports to the branches. Phylogenetic trees suggested the following relationships for the ingroup species; (A. antecessor sp. n. + ((Koroglus disparalatus + A. uludaghensis) + (A. turcicus + (A. niger + (A. ucari + A. babadaghi))) + ((A. tolunayi + (A. serbicus + A. antitauricus + A. burri)))). Considering the phylogenetic hypotheses and characters used in previous publications, Koroglus is put in synonymy with Anterastes, and a new combination is suggested for the only species of the former Anterastes disparalatus comb. n. A short remark is given about the characters used in the generic taxonomy of the group.

A new species of Mediapotamon Türkay & Dai, 1997 from a karst system in southwest China is described. The new species can be separated from congeners by the combination of a sharp and distinct epibranchial tooth, the anterolateral region lined with few scattered granules, the terminal segment of the male first gonopod distinctly bent with a constant diameter, and the position of the female vulvae. Mitochondrial 16S rDNA genetic data was used to investigate the systematic position of the new species, which is supported as a new taxon.

Simulium (Trichodagmia) Enderlein, 1934 has an unstable classification system. The broader concept of the subgenus includes five species-groups resulting from an extensive history of synonymisations, often outside of a phylogenetic framework. This concept also ignores relationship hypotheses with the Afrotropical subgenera S. (Anasolen) Enderlein, 1930, S. (Freemanellum) Crosskey, 1969, S. (Xenosimulium) Crosskey, 1969, and the Oviedoi species-group, with several Neotropical species of S. (Trichodagmia). We performed a morphological phylogenetic analysis to test the monophyly of S. (Trichodagmia), its species-groups, and their relationship with the above-mentioned subgenera and Oviedoi species-group. We analysed a data matrix with 69 terminal taxa and 62 characters under parsimony implied weights, with a range of concavities (k1–100), finding three categories of k. Our analysis concludes that S. (Trichodagmia) is not monophyletic, since Oviedoi and the Afrotropical subgenera group with its species-groups Tarsatum and Orbitale. Therefore, we propose a new classification for S. (Trichodagmia) by restricting it to the Orbitale species-group, revalidating S. (Hearlea) Vargas et al., 1946, S. (Hemicnetha) Enderlein, 1934, S. (Obuchovia) Rubtsov, 1947 and S. (Shewellomyia) Peterson, 1975, synonymysing S. (Xenosimulium) with S. (Anasolen), and erecting a new subgenus, S. (Disculter) subgen. nov. for Oviedoi. The geographical distribution of the groups involved is discussed.
