title: Revision of the subgenus Chalcotaenia of Paracupta (Coleoptera: Buprestidae: Chrysochroinae) and specification of Buprestis xanthocera Boisduval, 1835 as the type-species of the genus Paracupta

description: This dataset contains the digitized treatments in Plazi based on the original journal article Frank, David (2024): Revision of the subgenus Chalcotaenia of Paracupta (Coleoptera: Buprestidae: Chrysochroinae) and specification of Buprestis xanthocera Boisduval, 1835 as the type-species of the genus Paracupta. Zootaxa 5555 (4): 535-568, DOI: 10.11646/zootaxa.5555.4.3, URL: https://doi.org/10.11646/zootaxa.5555.4.3AbstractSubgenus Chalcotaenia Deyrolle, 1864 of Paracupta Deyrolle, 1864 is revised based on comparative study of extensive material including types of all described taxa. Buprestis xanthocera Boisduval, 1835 is specified as the type-species of genus Paracupta Deyrolle, 1864 and redescribed. Four new species are described: Paracupta (Chalcotaenia) gottwaldi sp. nov. from Solomon Islands: Ranongga Island; P. (C.) horaki sp. nov. from Indonesia: Seram Island; P. (C.) jakli sp. nov. from Solomon Islands: Guadalcanal and Malaita islands; P. (C.) laperousei sp. nov. from Indonesia: Bacan, Halmahera and Mandioli islands. Neotype is designated for Chrysodema lamberti Laporte de Castelnau & Gory, 1837 [Paracupta (Chalcotaenia) lamberti] and lectotype is designated for Buprestis xanthocera Boisduval, 1835 [Paracupta (Paracupta) xanthocera] to ensure their correct application and recognition in future. One new synonymy of subgenus: Paracupta Deyrolle, 1864 = Bojasinskia Hołyński, 2009 and one new synonymy of species: Buprestis xanthocera Boisduval, 1835 = Paracupta leveri Théry, 1934 are established. Paracupta isabellina Kerremans, 1900, P. rennelli Hołyński, 2014 and P. toxopeusi Obenberger, 1932 are transferred to subgenus Chalcotaenia. All herein included taxa are illustrated with colour photographs of habitus and the male aedeagus. A key to all taxa is presented.

title: Revision of the western Nearctic spider genus Cybaeina including the description of Neocybaeina gen. nov. and Rothaeina gen. nov. (Araneae: Cybaeidae: Cybaeinae)

description: This dataset contains the digitized treatments in Plazi based on the original journal article Bennett, Robb, Copley, Claudia, Copley, Darren (2023): Revision of the western Nearctic spider genus Cybaeina including the description of Neocybaeina gen. nov. and Rothaeina gen. nov. (Araneae: Cybaeidae: Cybaeinae). Zootaxa 5318 (1): 97-129, DOI: 10.11646/zootaxa.5318.1.5, URL: http://dx.doi.org/10.11646/zootaxa.5318.1.5AbstractThis paper is the last in a series revising the Nearctic Cybaeinae spider fauna (Araneae: RTA clade: Cybaeidae) exclusive of Cybaeozyga Chamberlin & Ivie. The forested habitats of the west coast of North America are home to a diverse array of endemic Cybaeinae spider taxa. Many of these have very restricted distributions, especially within an area of the western United States of America from the Olympic Peninsula of northwestern Washington to the northern half of the California Floristic Province of California, a well-known biodiversity hotspot. Here we revise the genus Cybaeina Chamberlin & Ivie recognizing three species: the type species Cybaeus minutus Banks (= Cybaeina minuta (Banks)), C. confusa Chamberlin & Ivie, and a single new species C. dixoni Bennett spec. nov. We describe Neocybaeina Bennett gen. nov. with type species Cybaeina xantha Chamberlin & Ivie (= Neocybaeina xantha (Chamberlin & Ivie) comb. nov.) and a single new species N. burnetti spec. nov. Finally we describe Rothaeina Bennett gen. nov. with type species Cybaeina sequoia Roth (= Rothaeina sequoia (Roth) comb. nov.) and four new species R. beaudini Bennett spec. nov., R. jamesi Bennett spec. nov., R. mackinleyi Bennett spec. nov., and R. petersoni Bennett spec. nov. In addition to descriptions of the genera and both sexes of their included species (except for N. burnetti spec. nov. and R. beaudini Bennett spec. nov. which are known from females only), we provide diagnoses, illustrations, distribution maps, and, for the three species of Cybaeina and the five of Rothaeina gen. nov., identification keys. In closing, we discuss conservation implications for this cryptic and infrequently collected group of western Nearctic Cybaeinae, several of which are short-range endemic species.

In this study, we describe and illustrate four new species of Scyphostelma: S. bolivianum, S. gracile, S. rotorum and S. solomonii, based on specimens collected in Bolivia and Peru. Phylogenetic analysis places S. bolivianum and S. gracile in a clade with S. harlingii, a species from southern Ecuador and central Peru, together as sister clade to the rest of Scyphostelma. Due to the size of flowers and the long-filiform peduncles and pedicels, we consider the two new species S. rotorum and S. solomonii and the new combination S. erikseniae a part of the S. harlingii group, for which an identification key is presented. Furthermore, four species names are lectotypified and six new combinations in Scyphostelma are made: S. fasciculiflorum, S. jaramilloi, S. purpurascens, S. quitense, S. stenospira and S. unguiculatum.

title: Antarctic Kinorhyncha: Seven new species from the Antarctic Peninsula

description: This dataset contains the digitized treatments in Plazi based on the original journal article Sørensen, Martin V., Macheriotou, Lara, Braeckman, Ulrike, Smith, Craig R., Ingels, Jeroen (2025): Antarctic Kinorhyncha: Seven new species from the Antarctic Peninsula. European Journal of Taxonomy 1000 (1): 1-102, DOI: 10.5852/ejt.2025.1000.2947, URL: https://europeanjournaloftaxonomy.eu/index.php/ejt/article/download/2947/13307Abstract. With only three named species, Antarctica is the continent with the least explored kinorhynch biodiversity. The present contribution provides the most comprehensive study of Antarctic kinorhynchs collected along the coast of the West Antarctic Peninsula. Quantitative samples were collected in three regions along the Peninsula: in Andvord Bay Fjord at the Danco Coast, in the Gerlache Strait, and on the open continental shelf west of the Peninsula. Comparison of the sampling areas suggests that the highest kinorhynch abundance was in the Gerlache Strait, where kinorhynchs were over six times more abundant than in Andvord Bay. Lowest abundance was on the open shelf, where the abundance was four times lower than in Andvord Bay. Among all examined specimens 98% were found in the top 4 cm of the sediment. All adult kinorhynchs were identified, and the study revealed the presence of the known Antarctic species Polacanthoderes shiraseae and at least seven species new to science: Condyloderes notios sp. nov., Polacanthoderes grzelakae sp. nov., Echinoderes ahlfeldae sp. nov., E. nataliae sp. nov., E. kathleenhannae sp. nov., E. antarcticus sp. nov., and E. crux sp. nov. In addition to the five new species of Echinoderes, two potentially known species are reported. Echinoderes aff. angustus shows close resemblance to the Arctic E. angustus, and the specimens only differed by their lack of a midventral fissure in segment 2, present in Arctic specimens of E. angustus only. A detailed examination of the E. angustus type material revealed new diagnostic details for the species, i.e., a complete mapping of sensory spots, presence of a middorsal protuberance between segments 10 and 11, and a tergal division of segment 11. Another unidentified species, Echinoderes aff. beringiensis / romanoi / xalkutaat, showed such close resemblance to three congeners that further studies are needed to identify clear diagnostic characters for the species, or alternatively clarify whether they should be synonymised. The comparisons prompted by the two unidentified species led to the suggestion of a new species group, the Echinoderes remanei species group, including E. remanei, E. angustus, E. beringiensis, E. cernunnos, E. drogoni, E. galadrielae, E. obtuspinosus, E. quasae, E. pennaki, E. romanoi, and E. xalkutaat. In addition, the Echinoderes aragorni species group is proposed, including the New Zealand species E. aragorni and the new species E. crux.

It is characterized by completely limbate vaginant laminae, tiny, convex, smooth laminal cells, excurrent costae and axillary antheridial buds. Its classification in subg. Polypodiopsis (Müll.Hal.) Broth. is discussed. Furthermore, F. pellucidus var. ripensis (Mitt.) Brugg.-Nann., comb. nov., stat. nov. is proposed and diagnosed. It differs from var. pellucidus Hornsch. in its mucronate apices and taller shoots with up to 55 leaf pairs. Thirdly, F. sciophyllus Mitt. subsp. capeverdensis Brugg.-Nann., subsp. nov. is described. It differs from F. s. subsp. sciophyllus by short costae that end 2-10 cells below the apex and tapering, acute leaf tips. It is endemic to the Cape Verde islands. The Asian-Polynesian F. ceylonensis Dozy & Molk. is for the first time reported for mainland Africa under this name (formerly known as e.g. F. borgenii). Several new synonyms are proposed. Fissidens magnicellulatus Brugg.-Nann. is subsumed under F. aciphyllus Dixon in Dixon & Wager; F. borgenii Hampe, F. sarcophyllus Müll.Hal. ex Dus., F. intralimbatulus Broth. & P.de la Varde, F. paucilimbatus P.de la Varde, F. aoristoloma P.de la Varde, F. intralimbatulus var. brevifolius P.de la Varde and F. norkettii P.de la Varde under F. ceylonensis; F. ugandae Dixon & P.de la Varde and F. gibbonii Bizot under F. ferrugineus Müll.Hal.; F. alomoides Müll.Hal. ex Dusén under F. hymenodon Besch.; F. cryptarum Müll.Hal. and F. cremersii Bizot & Onr. under F. pellucidus var. ripensis; F. grainvillei P.de la Varde under F. punctulatus Sande Lac.; F. nossianus Besch., F. motelayi Renauld & Cardot and F. ferrugineus var. pallidus Thér. are subsumed under F. schweinfurthii (Müll.Hal.) Paris). Fissidens ferrugineus and F. schweinfurthii are discussed, illustrated, diagnosed, and reinstated as species. The puzzling F. porrectus -complex is discussed, diagnosed, and some of its variants are illustrated. Fissidens subundatus Dury was described as pluripapillose, but appears to be mammillose. Its description is accordingly emended, the species is for the first time illustrated and a lectotype is designated. The species that are lectotypified or second-step-lectotypified in this paper are listed in the Appendix 1.
