title: Sinocrassula cuonaensis (Crassulaceae), a new succulent species from Southern Xizang, China

description: This dataset contains the digitized treatments in Plazi based on the original journal article Qiu, Xiang-Dong, Shi, Jia-Jing, Feng, Ya-Lin, Zhang, Feng-Di, Wang, Sheng-Wei, Wei, Neng, Wang, Qing-Feng (2025): Sinocrassula cuonaensis (Crassulaceae), a new succulent species from Southern Xizang, China. PhytoKeys 263: 115-128, DOI: 10.3897/phytokeys.263.159143AbstractSinocrassula cuonaensis, a new species of Crassulaceae from southern Xizang, is described and illustrated based on molecular and morphological evidence. Phylogenetically, it is sister to S. densirosulata with robust support. Morphologically, this new species is similar to S. indica var. viridiflava, S. densirosulata, and S. jiaozishanensis in having glabrous indumentum and long inflorescences, but it can be easily distinguished by its rosulate, thick, and near-cylindrical basal leaves, greenish white flowers, and sub-rectangular nectar scales. A key for identification of the genus, including the new species, is provided.

title: Corythoichthys quattuordecim, a new pipefish (Teleostei, Syngnathidae) from the Coral Sea

description: This dataset contains the digitized treatments in Plazi based on the original journal article Yuki, Daijiro, Fricke, Ronald, Motomura, Hiroyuki (2025): Corythoichthys quattuordecim, a new pipefish (Teleostei, Syngnathidae) from the Coral Sea. ZooKeys 1244: 113-119, DOI: 10.3897/zookeys.1244.153942AbstractA new species of pipefish, Corythoichthys quattuordecim sp. nov., is described based on five specimens collected from Vanuatu and the Chesterfield Islands, New Caledonia. The species inhabits relatively deeper waters (56–81 m) compared to most of its congeners, which are typically found in shallower habitats. It is distinguished by a unique combination of morphological features, most notably the presence of 14 trunk rings, a rare meristic character within the genus. Additional diagnostic characters include a total of 51–52 body rings, 27 dorsal-fin rays, 5.0–5.75 subdorsal rings, and 16 or 17 pectoral-fin rays. Proportional traits include head length 14.1–17.4 % of standard length, snout length 56.5–62.9 % of head length, dorsal-fin base length 48.3–54.9 % of head length, and snout depth 8.3–15.3 % of snout length. The opercle bears a denticulate longitudinal ridge with two or three black vertical stripes, and the dorsal fin originates behind the posterior margin of anal ring. The new species most closely resembles C. amplexus and an undescribed taxon reported by Fricke (2004) but is clearly distinguished from both based on the above characters.

title: Similar looking sisters: A new sibling species in the Pristimantis danae group from the southwestern Amazon basin (Anura, Strabomantidae)

description: This dataset contains the digitized treatments in Plazi based on the original journal article Köhler, Jörn, Glaw, Frank, Aguilar-Puntriano, César, Castroviejo-Fisher, Santiago, Chaparro, Juan C., De la Riva, Ignacio, Gagliardi-Urrutia, Giussepe, Gutiérrez, Roberto, Vences, Miguel, Padial, José M. (2024): Similar looking sisters: A new sibling species in the Pristimantis danae group from the southwestern Amazon basin (Anura, Strabomantidae). Zoosystematics and Evolution 100 (2): 565-582, DOI: 10.3897/zse.100.119143AbstractWe describe a new frog species that is the sibling of Pristimantis reichlei. These two sister species inhabit the Amazonian lowlands and adjacent foothills of the Andes, from central Bolivia to central Peru. Pristimantis reichlei occurs from central Bolivia to southern Peru (Alto Purús National Park), while the new species occurs from northern Bolivia (Departamento Pando) to Panguana in central Peru (Departamento Huánuco), at elevations between 220 and 470 m a. s. l. In spite of their morphological crypsis, these siblings occur in syntopy without evidence of interbreeding (in the Alto Purús area) and are recovered as reciprocally monophyletic. Their uncorrected pairwise genetic distances in the 16 S rRNA gene range from 9.5 – 13.5 %, and their advertisement calls differ in both qualitative and quantitative traits. Moreover, our study found uncorrected pairwise distances within the new species of up to 5.0 % and up to 9.3 % within P. reichlei. We therefore cannot rule out the possible existence of hybrids or additional species-level lineages hidden in this complex. Furthermore, we found another potential pair of sibling species composed of P. danae and an unnamed lineage, with divergences of 9.4 % in the 16 S gene, whose in-depth analysis and taxonomic treatment are pending future revision. With the new nominal species, the Pristimantis danae species group now includes 20 species, distributed across the upper Amazon basin and in the eastern Andes, from western Brazil to Bolivia and Peru. Our study, together with an increasing number of other studies, indicates that sibling species are far from being rare among Amazonian amphibians and that species resolution remains low even for groups that have received considerable attention in recent years.

title: Relationships of a new fossorial Microcambevinae catfish species from southern Brazil supporting multiple dorsal-fin losses in Listrura (Siluriformes, Trichomycteridae)

description: This dataset contains the digitized treatments in Plazi based on the original journal article Costa, Wilson J. E. M., Feltrin, Caio R. M., Mattos, José L. O., Vilardo, Paulo J., Katz, Axel M. (2025): Relationships of a new fossorial Microcambevinae catfish species from southern Brazil supporting multiple dorsal-fin losses in Listrura (Siluriformes, Trichomycteridae). Zoosystematics and Evolution 101 (3): 1177-1185, DOI: 10.3897/zse.101.139205AbstractExtreme reduction or loss of fins is a common evolutionary feature in fossorial and semifossorial trichomycterids. Here, we analyse the possible occurrence of independent evolutionary events of dorsal fin loss in Listrura, a genus of fossorial species endemic to the Atlantic Forest of eastern Brazil, in a molecular phylogenetic context involving all species of the genus, including three nominal species lacking a dorsal fin and another one that is described here. Ancestral state reconstruction analysis indicated the occurrence of three independent events of dorsal fin loss: one in the subgenus Listrura (L. menezesi) and two in the subgenus Prolistrura, in L. depinnai and in the clade comprising L. boticario and the new species. Osteological comparisons indicate that there are no intermediate stages in the genus; species either possess a well-developed dorsal fin or completely lack both the fin and its internal skeletal support. It was not possible to identify distinct environmental characteristics or ecological preferences between species with and without a dorsal fin. The new species is distinguished from L. boticario, its hypothesised sister species, by a different colour pattern, a different number of caudal-fin procurrent rays and interopercular odontodes, and a larger eye.

title: Echiniscus gemmatus sp. nov. (Heterotardigrada: Echiniscidae; the spinulosus morphogroup) from Macau, China

description: This dataset contains the digitized treatments in Plazi based on the original journal article Leong, Weng-I, Yu, Jr-Kai, Tsai, Isheng Jason, Kaczmarek, Łukasz, Lee, Yi-Chien, Lin, Chung-Ping (2024): Echiniscus gemmatus sp. nov. (Heterotardigrada: Echiniscidae; the spinulosus morphogroup) from Macau, China. Zootaxa 5551 (2): 333-352, DOI: 10.11646/zootaxa.5551.2.5, URL: https://doi.org/10.11646/zootaxa.5551.2.5AbstractThe study of tardigrades in urban environments, particularly in natural areas within cities, has been significantly overlooked. A recent discovery of a new species of tardigrade in lichens collected from Mong Há Hill Municipal Park in Macau provides new insights into the population of tardigrades within the city. Echiniscus gemmatus sp. nov. was identified based on distinct morphological characters, morphometric measurements, and DNA sequences of nuclear (18S rRNA, 28S rRNA, ITS-1, and ITS-2), as well as a mitochondrial (COI) markers. Our research indicates that Ech. gemmatus sp. nov. belongs to the Echiniscus spinulosus morphogroup and is most similar to Ech. tropicalis, as confirmed by both qualitative characters and DNA barcoding. Notably, Echiniscus gemmatus sp. nov. exhibits distinct characteristics that differentiate it from other members of the Ech. spinulosus morphogroup, including (1) often asymmetrical short spines B, C, Cd, Dd, and E, and (2) larger and more visible pores tend to be concentrated in the median and posterior portions of the first and second paired plates, with their visibility gradually decreasing towards the anterior and lateral suture regions.

title: 2 D Geometric morphometrics of the first lower molar of the genus Meles Brisson, 1762 including new badger evidence from the Lower Pleistocene Quibas site (Murcia, Spain)

description: This dataset contains the digitized treatments in Plazi based on the original journal article Rosas, Antonio, Soler-Fajardo, Ana, Garcia-Tabernero, Antonio, Huguet, Rosa, Vallverdú, Josep, Fidalgo, Darío, Galli, Emilia, Piñero, Pedro (2023): 2 D Geometric morphometrics of the first lower molar of the genus Meles Brisson, 1762 including new badger evidence from the Lower Pleistocene Quibas site (Murcia, Spain). Comptes Rendus Palevol 22 (7): 91-107, DOI: 10.5852/cr-palevol2023v22a7, URL: http://dx.doi.org/10.5852/cr-palevol2023v22a7ABSTRACTBadgers belong to the genus Meles Brisson, 1762, which comprise four extant species (M. anakuma Temminck, 1844, M. leucurus (Hodgson, 1847), M. canescens Blanford, 1875, and M. meles (Linnaeus, 1758)). The genus is included in the subfamily Melinae Bonaparte, 1838, a polyphyletic group of Eurasian mustelids whose evolutionary relationships need further clarification. The evolutive relationships of the genus are complex and far from being resolved. This work aims to describe a nearly 1 Ma unpublished badger mandible from the Sierra de Quibas (Murcia) and to help clarify the evolutionary patterns of Euroasiatic badgers. To this end, we used 2D geometric morphometric techniques to measure 57 landmarks and semilandmarks in 79 first lower molars (m1) of Meles, ranging from Pleistocene to extant species. Our results show evidence for differentiating between primitive badgers and living species of Meles. The new m1 of Meles from the Quibas site is more gracile (relatively narrower and longer) than the other Eurasian extinct species, and shows that this specimen can be placed in the subspecies M. meles meles (Linnaeus, 1758). Our results also show that the denomination of M. meles atavus Kormos, 1914 as a related subspecies with a primitive morphology is morphologically supported. Therefore, we conclude that the living subspecies of badger M. meles meles was already differentiated in the south of the Iberian Peninsula at around 1 Ma, but some primitive remnant populations persisted in the north of the Iberian Peninsula, for which we recognize the subspecies M. meles atavus.

title: Passiflora brauliensis, a new species of Passiflora supersection Laurifoliae (Passifloraceae) from the volcanic forest of Costa Rica

R., Rodríguez-Barboza, Gared, Álvarez-Alcázar, Leonardo (2023): Passiflora brauliensis, a new species of Passiflora supersection Laurifoliae (Passifloraceae) from the volcanic forest of Costa Rica. Phytotaxa 584 (2): 121-129, DOI: 10.11646/phytotaxa.584.2.5, URL: http://dx.doi.org/10.11646/phytotaxa.584.2.5AbstractA new species from Costa Rica is described following a closer analysis of the Passiflora nitida complex. Given that the actual true identification of Passiflora nitida typified from Venezuela but distributed throughout South America was rather poorly constrained, the new species presented here was long identified incorrectly as supposedly being a form of P. nitida, for it sharing several floral characteristics. Following intense revision of the source literature, supplemented by fieldwork across Central America, the Costa Rican accessions of “ Passiflora nitida ” appeared to be significantly different from its South American counterpart in several morphological and habitational characteristics. While it was found that true Passiflora nitida only inhabits non-volcanic terrains, Passiflora brauliensis sp. nov. presented in this paper attributes to be the only member of this complex endemic to solely volcanic regions, where it is found in wet lowland to premontane transitional forest on the eastern flanks of Costa Rica’s most active volcanoes. The ecology, distribution, and association with the Passiflora nitida complex is highlighted, as well as its relationship with the other species within Passiflora supersect. Laurifoliae found throughout Latin America.

This region of China has not had much previous attention focused on the biodiversity of freshwater algae. The new species, Neidium convolutum Y.Liu & Kociolek, is very distinctive compared with other known Neidium species, having torsion of the valves along the apical axis, large linear valves with wedge-shaped apices, oblique striae and volate occlusions in the areolae. We present a formal description of this species based on both light and scanning electron microscopic observations, and compare it with other, morphologically-similar species.
