title: Another ghost of Gondwana-Progradungula barringtonensis Michalik & Smith, sp. nov., a new species of the relict spider genus Progradungula (Araneae: Gradungulidae) from a temperate rainforest in eastern Australia

description: This dataset contains the digitized treatments in Plazi based on the original journal article Michalik, Peter, Smith, Helen M., Milledge, Graham, Harms, Danilo (2024): Another ghost of Gondwana-Progradungula barringtonensis Michalik & Smith, sp. nov., a new species of the relict spider genus Progradungula (Araneae: Gradungulidae) from a temperate rainforest in eastern Australia. Austral Entomology 63 (1): 72-81, DOI: 10.1111/aen.12675, URL: http://dx.doi.org/10.1111/aen.12675AbstractOdd-clawed spiders (Gradungulinae), which are considered to be ‘living fossils’, are a faunal element of the mesic forests of eastern Australia and the South Island of New Zealand. To date, 16 species in seven genera are known, with most being highly endemic and hard to find, explaining their scarcity in collections worldwide. Particularly noteworthy is the Australian genus Progradungula that includes only two relict species from eastern Australia (Progradungula carraiensis from the Carrai limestone caves in northern New South Wales and Progradungula otwayensis from Nothofagus rainforests in the Otway Range, southern Victoria) and are known from only a handful of adult specimens. Both species are large nocturnal predators with a rather cryptic lifestyle, which construct unique ladder-like catching webs composed of non-combed and combed cribellate silk with exceptional properties. Here, we describe a new relict species, Progradungula barringtonensis Michalik & Smith, sp. nov., from isolated Nothofagus forest patches in Barrington Tops National Park (NSW, Australia). The male of this species is significantly larger than those of P. carraiensis and P. otwayensis and exhibits characteristics of the male genitalia of both species. The webs are similar to those of the other Progradungula species. Field observations revealed that the catching ladder had few looping segments, similar to P. otwayensis, but an immature in captivity constructed webs with more looping segments, similar to P. carraiensis, supporting the previously proposed hypothesis that food availability may explain the plasticity of the catching ladder structure.

title: A new species of the genus Achalinus (Squamata: Xenodermidae) from Ningshan County, Shaanxi Province, China

description: This dataset contains the digitized treatments in Plazi based on the original journal article YANG, DIAN-CHENG, HUANG, RU-YI, JIANG, KE, BURBRINK, FRANK T., GONG, YAN-AN, YU, JING, ZHANG, YI, HUANG, TIAN-QI, HUANG, SONG (2022): A new species of the genus Achalinus (Squamata: Xenodermidae) from Ningshan County, Shaanxi Province, China. Zootaxa 5190 (1): 127-140, DOI: 10.11646/zootaxa.5190.1.5, URL: http://dx.doi.org/10.11646/zootaxa.5190.1.5AbstractA new species of odd-scaled snake in the genus Achalinus is described from Ningshan County, Shaanxi Province, China, based on seven female specimens. Morphologically, the new species can be distinguished from its congeners by the following combination of characters: (1) dorsum iridescent and uniformly dark brown in preservative, longitudinal vertebral line absent; (2) light brown beneath; (3) dotted black streak in the middle of the subcaudals absent; (4) tail length relatively short, TaL/ToL 12–16%, in females; (5) fewer subcaudals, 41–46 in females; (6) dorsal scales 23 rows throughout, strongly keeled; the outer-most rows on both sides are also keeled and slightly enlarged; (7) one loreal; (8) internasal not fused to prefrontal; (9) suture between internasals is similar in size when compared to the suture between prefrontals; (10) preocular and postocular absent; (11) 6 supralabials; (12) 5 infralabials, the first 3 (rarely 2) touching the first pair of chin shields; (13) 3 pairs of chin shields. A phylogenetic analysis using mitochondrial gene, cytochrome c oxidase subunit 1 (CO1), showed that this new species forms a monophyletic group with strong support. In addition, the uncorrected p -distances between the new species and other known congeners ranged from 3.4% to 13.0%. The recognition of the new species increases the number of described Achalinus species to 21.

title: Response to Britz (2022) regarding the validity of the giant sunfish Mola alexandrini (Ranzani, 1834) (Teleostei: Molidae)

description: This dataset contains the digitized treatments in Plazi based on the original journal article Sawai, Etsuro, Nyegaard, Marianne (2023): Response to Britz (2022) regarding the validity of the giant sunfish Mola alexandrini (Ranzani, 1834) (Teleostei: Molidae). Zootaxa 5383 (4): 561-574, DOI: 10.11646/zootaxa.5383.4.7, URL: https://www.mapress.com/zt/article/download/zootaxa.5383.4.7/52469AbstractThe small family of ocean sunfishes has a long and complicated taxonomic and nomenclatorial history dating back several centuries. Most recently, Britz (2022) questioned the validity of Mola alexandrini (Ranzani, 1839) as the valid name for Mola sp. A sensu Yoshita et al. (2009). Specifically, he questioned the authenticity of the purported Orthragoriscus alexandrini holotype rediscovered by Sawai et al. (2018) due to uncertainties regarding the original units of measurement, along with discrepancies between the original illustration and the purported holotype. He also questioned the reliability of the illustration to reflect the fresh morphology, and the adequacy of the species description (sans illustration and holotype) to link it to any of the currently recognized Mola species. In summary, Britz (2022) opined that M. alexandrini is a species inquirenda. Here we respond to Britz’s concerns with the findings from an additional literature review. Firstly, the original species description appears to give measurements in ‘Parisian units’, yielding a discrepancy in length with the purported holotype within human error. However, due to various uncertainties, length does not appear to be a robust piece of evidence to neither confirm nor refute the specimen’s authenticity. Secondly, the morphological differences between the original illustration and the purported holotype were found to be within the expected level of accuracy for Mola illustrations at the time, by both Ranzani and others. Thirdly, a contemporaneous publication describes how Ranzani himself bought the specimen which became the Or. alexandrini holotype, suggesting he would likely have seen it in its fresh state, rendering it unlikely he would have produced a species description and illustration incongruent with this. Fourthly, re-examining the original species description suggests this provides adequate and sufficient information to link Or. alexandrini to Mola sp. A, even in the absence of a holotype. Finally, during this review, we came upon an even older paper describing Or. alexandrini, and we conclude that the currently valid name for Mola sp. A sensu Yoshita et al. (2009) is Mola alexandrini (Ranzani, 1834).

title: Carcinoplax mistio Ng & Mitra, 2019 (Crustacea, Decapoda, Goneplacidae): additional records and genetic differentiation of allied taxa

description: This dataset contains the digitized treatments in Plazi based on the original journal article Prema, Mani, Yang, Chien-Hui, Ravichandran, Samuthirapandian, Ng, Peter K. L. (2024): Carcinoplax mistio Ng & Mitra, 2019 (Crustacea, Decapoda, Goneplacidae): additional records and genetic differentiation of allied taxa. ZooKeys 1214: 91-103, DOI: 10.3897/zookeys.1214.131500AbstractThe goneplacid crab, Carcinoplax mistio Ng & Mitra, 2019, was originally described from West Bengal, India, in the northern Indian Ocean. Additional material of C. mistio from off Tamil Nadu in the southeast of India revealed a high degree of size-associated variation in the structures of the anterolateral tooth of the carapace, chelipeds, and male and female pleons. In addition to an in-depth morphological examination of C. mistio, this study also records the natural coloration of the species and conducts a genetic comparison (with mitochondrial COI and 16 S rRNA genes) with its close relatives, C. haswelli (Miers, 1884) and C. purpurea Rathbun, 1914. Molecular comparison of C. mistio with its morphologically closest congener, C. haswelli from northern Australia and the western Pacific, corroborates their status as separate species. The genetic sequence of C. mistio, however, is similar to that of C. purpurea from the West Pacific, although these two species can easily be distinguished by distinct carapace and ambulatory leg characters. The present study provides some possible explanations for the genetic and morphological incongruence observed between C. mistio and C. purpurea and highlights the need for a detailed molecular study for Carcinoplax H. Milne Edwards, 1852, to appreciate the evolution of various morphological characters in the genus.

title: Homatula gelao (Cypriniformes, Nemacheilidae), a new nemacheiline species of loach from the upper Yangtze River basin in Guizhou Province, southwestern China

description: This dataset contains the digitized treatments in Plazi based on the original journal article Xiao, Gui-Bang, Guo, Qi-Wei, Cao, Liang, Lin, Jia, Deng, Wei-Xi, Xiao, Qi-Qi, Zhou, Lin, Zhang, Hao-Ran, Fang, Ding-Zhi (2025): Homatula gelao (Cypriniformes, Nemacheilidae), a new nemacheiline species of loach from the upper Yangtze River basin in Guizhou Province, southwestern China. Zoosystematics and Evolution 101 (1): 257-271, DOI: 10.3897/zse.101.141973AbstractHomatula gelao, a new species, is here described from the Wu-Jiang of the Yangtze River basin in Guizhou province, southwestern China. This new species belongs to the elongate-bodied group of Homatula defined by having a complete lateral line, sparsely scales hidden in skin on the predorsal body, and a slender body with a uniform depth. It, along with H. variegata, is distinguished from all other species of this group in having a broadly rounded caudal fin and a small number of scales sparsely scattered over the predorsal body. Both differ in body coloration, striped pattern on the predorsal body, and caudal-peduncle length. The validity of the new species is corroborated by distinct genetic distance divergence with closely related congeneric species and its monophyly recovered in a mtDNA COI gene-based phylogenetic analysis. It is separated from other Homatula species by a minimum of 8.2 % Kimura 2 - parameter distance in the COI gene.

title: Species delimitation in the genus Klebsormidium (Klebsormidiophyceae, Charophyta), including description of Klebsormidium mirabile sp. nov. with high content of polyunsaturated fatty acids

description: This dataset contains the digitized treatments in Plazi based on the original journal article Tukhtaboeva, Yulduzkhon, Krivina, Elena, Redkina, Vera, Portnov, Aleksey, Sinetova, Maria, Temraleeva, Anna (2025): Species delimitation in the genus Klebsormidium (Klebsormidiophyceae, Charophyta), including description of Klebsormidium mirabile sp. nov. with high content of polyunsaturated fatty acids. PhytoKeys 266: 53-74, DOI: 10.3897/phytokeys.266.158514AbstractThe genus Klebsormidium is a cosmopolitan filamentous alga that belongs to the phylum Charophyta and inhabits a wide range of environments, primarily freshwater, soil, and aerial habitats. Its basal position on the Streptophyta phylogenetic tree, widespread distribution and significant functional role make the genus Klebsormidium an important object for phycological research. To advance the molecular phylogeny of Klebsormidium, we conducted the first comparative evaluation of six species delimitation methods – ASAP (Assemble Species by Automatic Partitioning), LocMin (Local Minima), KoT (K over Theta), GMYC (Generalized mixed Yule-coalescent), mlPTP (Poisson Tree Process with Maximum Likelihood), and bPTP (Poisson Tree Process with Bayesian inference) – using rbc L and concatenated ITS 2 – rbc L fragments. The accuracy of these methods was further validated against molecular, morphological, and ecological data. According to an integrative approach, Klebsormidium mirabile sp. nov. was proposed as a new charophyte species from soil of the Fergana Valley, Uzbekistan. In addition, a study on the fatty acid composition showed that the authentic strain VKM Al-436 of this new species of Klebsormidium is a potential source of polyunsaturated fatty acids, including linoleic, α-linolenic, and hexadecatrienoic acids.

title: Quercus purhepecha (Fagaceae), a new species of shrub oak endemic to the state of Michoacán, Mexico

description: This dataset contains the digitized treatments in Plazi based on the original journal article Luna-Bonilla, Oscar Angel De, González-Rodríguez, Antonio, Rodríguez-Correa, Hernando, Piña-Torres, Javier, Coombes, Allen J., Valencia-A, Susana (2024): Quercus purhepecha (Fagaceae), a new species of shrub oak endemic to the state of Michoacán, Mexico. Phytotaxa 670 (4): 191-202, DOI: 10.11646/phytotaxa.670.4.1, URL: https://doi.org/10.11646/phytotaxa.670.4.1AbstractWithin the genus Quercus there are species with a shrubby habit that have been little studied worldwide. In Mexico, several shrub species within section Quercus are taxonomically highly problematic. These include eight named taxa that share traits such as abaxially tomentose leaves and growth of stems from one or multiple rhizomes, and there is evidence of additional undescribed species. Here, Quercus purhepecha is described and illustrated as a new tomentose shrubby white oak species, with a very restricted distribution within the Cuitzeo basin in the Trans-Mexican Volcanic Belt (TMVB), Michoacán state, Mexico. This new species is morphologically compared with Q. frutex, Q. microphylla and Q. repanda, which are similar taxa also distributed in the TMVB. In addition, a potential distribution model of Q. purhepecha for the Cuitzeo basin is presented.

title: Towards a revision of the bamboo corals (Octocorallia): Part 4, delineating the family Keratoisididae

description: This dataset contains the digitized treatments in Plazi based on the original journal article Watling, Les, Saucier, Esprit Heestand, France, Scott C. (2022): Towards a revision of the bamboo corals (Octocorallia): Part 4, delineating the family Keratoisididae. Zootaxa 5093 (3): 337-375, DOI: 10.11646/zootaxa.5093.3.4AbstractThe systematics of bamboo corals of the Family Keratoisididae are evaluated using both DNA sequences and morphological data. Sequence data were obtained from 398 specimens, from which 77 unique haplotypes representing the mtMutS and 18S gene regions were identified. These were aligned with sequences downloaded from GenBank from an additional 12 keratoisids and 6 octocoral outgroups. Phylogenetic analyses recovered seven well-supported major clades, the most recently derived of which consists of several subclades. Each clade and subclade can be characterized by a suite of morphological characters that include axis construction, branching pattern, polyp form, and sclerite type and arrangement. This analysis also shows that keratoisid genera described&gt;100 years ago are paraphyletic and need revision and that a large number of new genera will need to be described.

The new species is diagnosed from all congeners, except M. moisae and M. pirauba, by having a high number of scales in the longitudinal series (43–46 vs. 23–41 in other Moenkhausia species). It can also be distinguished from the aforementioned species based on the combination of the following characters: a single humeral blotch, 21–25 branched anal-fin rays, and a round and symmetrical caudal blotch not continuous anteriorly with the dark midlateral stripe. The new tetra herein described represents an additional, possibly endemic, taxon from the headwaters draining from Serra do Cachimbo, in the Brazilian Shield.
