title: Systematic revision of Afrogecko ansorgii (Boulenger, 1907) (Sauria: Gekkonidae) from western Angola

description: This dataset contains the digitized treatments in Plazi based on the original journal article Lobon-Rovira, Javier, Conradie, Werner, Pinto, Pedro Vaz, Keates, Chad, Edwards, Shelley, Plessis, Anton Du, Branch, William R. (2022): Systematic revision of Afrogecko ansorgii (Boulenger, 1907) (Sauria: Gekkonidae) from western Angola. Zootaxa 5124 (4): 401-430, DOI: 10.11646/zootaxa.5124.4.1AbstractHere we provide the first phylogenetic analysis that include Afrogecko ansorgii and a detailed morphological comparison with other species of leaf-toed geckos. For this purpose, we used two mitochondrial (16S, ND2) and four nuclear (RAG1, RAG2, CMOS, PDC) genes to produce a robust phylogenetic reconstruction. This allowed us to show that A. ansorgii is not related as previously believed to circum-Indian Ocean leaf-toed geckos and is rather more closely related to other Malagasy leaf-toed geckos. Additionally, we explore and compare osteological variation in A. ansorgii skulls through High Resolution X-ray Computed Tomography with previously published material. This allowed us to describe herein a new genus, Bauerius gen. nov., and additionally provide a detailed redescription of the species (including the first description of male material), supplementing the limited original description and type series, which consisted of only two females.

title: Description of a new species of Aegla (Decapoda, Anomura) from the Paraná 3 hydrographic basin, Brazil

description: This dataset contains the digitized treatments in Plazi based on the original journal article Arantes, Tiago, Souza-Shibatta, Lenice, Teixeira, Gustavo Monteiro (2024): Description of a new species of Aegla (Decapoda, Anomura) from the Paraná 3 hydrographic basin, Brazil. Zootaxa 5418 (4): 371-384, DOI: 10.11646/zootaxa.5418.4.5, URL: http://dx.doi.org/10.11646/zootaxa.5418.4.5AbstractFreshwater crustaceans of the genus Aegla are endemic to southern South America, and present greater richness in the river basins of the state of Rio Grande do Sul, Brazil. However, recent studies have shown the enormous potential for discovering new species of Aegla in the state of Paraná. In the last six year the number of species recorded has almost doubled, increasing from 9 to 16. In the present work, we expand the current knowledge about the diversity of Aegla in a set of poorly explored drainage basins in the western region of the state and describe a new species, Aegla urussanga n. sp., based on morphological and molecular evidence. A combination of morphological characters supports the new species: orbital spine absent, non-elevated epigastric prominences, robust protogastric lobes with scales, anterior dorsal margin of epimeron 2 armed and with pronounced concavity, sub-rectangular palmar crest of chelipeds, internal margin of the ventral face of the ischium of the cheliped with a proximal stout spine, a distal stout spine, and up to three tubercles with spiniform scales. The molecular data, based on partial COI sequences, also support the distinction of the new species from others that occur in adjacent river basins. The species with the smallest genetic distance from A. urussanga n. sp. is Aegla castro Schmitt, 1942 which occurs in the Iguaçu River basin. The new species occurs in distinct streams, probably interconnected in the past and currently isolated by the Itaipu reservoir and is the second species of Aegla described from the complex of drainage basins called Paraná 3 basin.

Morphological comparisons indicated the new species is similar to L. filiformis and L. cordata, but differs from L. brachyota inflorescences 3-or 5-flowered, lip shorter than petals, hypochile thickly fleshy, epichile cordate adaxially with 7 or 9 papillate longitudinal ridges. Molecular analysis based on the nuclear ribosomal ITS and plastid sequences (matK, rbcL, and trnL-trnF) shows that it is a new species.

(Ascomycota: Pleosporaceae) from Vigna unguiculata in China. Phytotaxa 556 (3): 281-290, DOI: 10.11646/phytotaxa.556.3.4, URL: http://dx.doi.org/10.11646/phytotaxa.556.3.4AbstractAlternaria is a widely distributed fungal genus served as saprophytes, endophytes and pathogens. An Alternaria species was isolated from Vigna unguiculata in Inner Mongolia Autonomous Region of China. The strains were determined based on morphological characteristics and multi-locus phylogenetic analyses including the internal transcribed spacer of rDNA region (ITS), glyceraldehydes-3-phosphate dehydrogenase (GAPDH), RNA polymerase second largest subunit (RPB 2) and translation-elongation factor 1 alpha (TEF 1). The results indicated that it was a new species, which described and illustrated as Alternaria vignae sp. nov. in this study. Phylogenetic analyses showed that the species formed a well-supported clade (sect. Helianthiinficientes) close to A. helianthiinficiens.

Caucasian Entomological Bulletin 17 (1): 57-60, DOI: 10.23885/181433262021171-5760, URL: http://dx.doi.org/10.23885/181433262021171-5760Abstract. A pale giant oak aphid Stomaphis wojciechowskii Depa, 2012 from the tribe Stomaphidini (Hemiptera: Aphididae: Lachninae) is recorded for the fauna of Belarus for the first time. The species was collected twice in October 2019 and 2020 in the vicinity of Gomel from deep bark cracks and in the ant tunnels of Lasius brunneus under the bark of Quercus robur in a deciduous forest. Currently Stomaphis wojciechowskii is recorded from open deciduous and mixed forests in Poland, Hungary, Romania, Slovakia, Slovenia and Great Britain. Apparently, this species previously remained unrecognized due to its external similarity to S. quercus (Linnaeus, 1758) and cryptic mode of life. The morphological description of the studied forms is given. Brief information on the lifestyle, distribution and bionomics of this species is given.

Zootaxa 5403 (2): 239-255, DOI: 10.11646/zootaxa.5403.2.3, URL: http://dx.doi.org/10.11646/zootaxa.5360.3.8AbstractHydroporus queneyi sp. n. is described from the area of Montpellier in southern France. It is a member of the Hydroporus normandi -complex (within the H. memnonius -group) and shares with other species of the complex the typical suite of morphological features associated with a semi-subterranean ecology. The new species differs from all previously known species of the complex by the antennomeres V –XI distinctly darkened, and by a diagnostic combination of features notably of the habitus, surface sculpture and pubescence, aspect of the metacoxal lines and posterior wing venation. Its morphology is compared with that of related species, as well as described and illustrated. Collecting circumstances for the new species are described and an updated map of the distribution of H. normandi -complex species is provided. Newly produced partial sequences of the mitochondrial marker CO1 from specimens of H. queneyi sp. n., H. galloprovincialis Manuel, 2013 and two subspecies of H. normandi Régimbart, 1903 were analysed together with publicly available sequences. In the resulting CO1 tree, haplotypes from the respective morphospecies are well separated within the H. normandi -complex, and H. queneyi sp. n. is positioned closer to the Balearic Islands endemic H. lluci Fery, 1999 than to its continental relatives H. galloprovincialis and H. normandi.

Zootaxa 5099 (2): 201-220, DOI: 10.11646/zootaxa.5099.2.3AbstractA new species of Diploderma is described from the upper Salween River Valley in eastern Tibet, China based on morphological and genetic data. The new species is morphologically most similar and phylogenetically closely related to D. laeviventre, but it can be easily diagnosed by having distinct conical scales on the post rictal region of the head, distinctively keeled ventral head and body scales, and different coloration of gular spots and dorsolateral stripes in both sexes. The taxonomic discovery further highlights the underestimated diversity of the genus and the importance of habitat conservation of the neglected hot-dry valley ecosystems in the Hengduan Mountain Region of China.

We therefore reduce R. tengchongensis and R. yanshanensis to the synonymy of R. trigonus herein.
