Species Being

Previous descriptions of members of Fabricia oregonica Banse, 1956, have distinguished it by the presence of only narrowly hooded inferior thoracic notochaetae, in contrast to the presence of pseudospatulate chaetae in median chaetigers of the type species, F. stellaris (Müller, 1774). In other respects, past descriptions of specimens to which F. oregonica refers have lacked the necessary detail to clearly determine generic placement, and the type material is in poor condition. Recently collected specimens matching earlier descriptions are used to redescribe members of the species. An exclusive sister-group relationship does not exist between F. stellaris and F. oregonica, precluding the latter species being assigned to Fabricia. Fabricia oregonica is therefore placed in a new genus, Bansella. Under the view that all taxa, whether phylogenetic or specific, are explanatory hypotheses, it is pointed out that the monotypic Bansella cannot be defined as such a hypothesis. While the International Code of Zoological Nomenclature requires that names be defined by way of ‘differentiating characters,’ this approach is at odds with the scientific endeavor of biological systematics to infer explanatory hypotheses, colloquially known as taxa. In addition to only having narrowly hooded inferior notochaetae, members of B. oregonica differ from F. stellaris specimens in having abdominal uncini with a much shorter manubrium. The ventral, lobe-like collar in B. oregonica specimens is also distinctly rectangular as opposed to triangular. Members of the two species are similar in that females have pigmented spermathecae in the bases of branchial lobes and spermiogenesis occurs in males in chaetigers 3–8.

The Subject

One of the oldest fossil horseshoe crabs figured in the literature is Entomolithus lunatus Martin, 1809, a Carboniferous species included in his Petrificata Derbiensia. While the species has generally been included within the genus Belinurus Bronn, 1839, it was recently used as the type species of the new genus Parabelinurus Lamsdell, 2020. However, recent investigation as to the appropriate authority for Belinurus (see Lamsdell and Clapham, 2021) revealed that all the names in Petrificata Derbiensia were suppressed in Opinion 231 of the International Commission on Zoological Nomenclature (1954) for being consistently nonbinomial under Article 11.4 of the International Code of Zoological Nomenclature (ICZN) (International Commission on Zoological Nomenclature, 1999). Despite the validation of several species names for anthozoans, brachiopods, and cephalopods described in Petrificata Derbiensia in subsequent rulings (International Commission on Zoological Nomenclature, 1956a, b), Belinurus lunatus has not been the subject of any subsequent Commission ruling or opinion, and so its use in Petrificata Derbiensia remains suppressed. The Belinurus lunatus species name was used in several subsequent publications during the 1800s, none of which made the name available under ICZN article 11.5; Parkinson (1811) is also suppressed for being nonbinomial, while Woodward (1830), Buckland (1837), Bronn (1839), and Baily (1859) refer to the species only as a synonym of Belinurus trilobitoides (Buckland, 1837) through citation to the suppressed Pretificata Derbiensia. The first author to make Belinurus lunatus an available name was Baldwin (1905), who used the name in reference to a new figured specimen from Sparth Bottoms, Rochdale, UK, but again as an explicit junior synonym of Belinurus trilobitoides (Buckland, 1837). Therefore, it was not until Eller (1938) treated B. lunatus as a distinct species from B. trilobitoides that B. lunatus became an available name as per ICZN Article 11.6.1 under the authorship of Baldwin (1905) following ICZN Article 50.7.

It has been pointed out that there is an error in our recent paper (Rentz et al., 2012). On p. 24 we designated Miniagraecia viridis Rentz, Su, Ueshima sp. nov. as the type species of  the new genus Miniagraecia. However there is no such species.  There was a manuscript change in the name of the species and we did not catch it in the type species designation.  Miniagraecia is therefore a nomen nudum. Miniagraecia viridis is not a nominal species and Miniagraecia does not now have a fixed type species (International Code of Zoological Nomenclature, Article 67.1).

The spider genus Putaoa new genus (Araneae, Pimoidae) is described to place two species of pimoids from China, Putaoa huaping new species (the type species) and P. megacantha (Xu & Li, 2007) new combination. Parsimony analysis of morphological characters provides support for the monophyly of Putaoa and for its sister group relationship to the genus Weintrauboa Hormiga, 2003 and corroborates the monophyly of Pimoidae.

Abstract A monotypic genus Proparadilepis Kornyushin et Greben, gen. n. (type species: Proparadilepis plegadissaakovae sp. n.) is erected. It is similar to the genera Paradilepis Hsu, 1935, Ascodilepis Guildal, 1960 and Dendrouterina Fuhrmann, 1912 and differs from them by the number and shape of rostellar hooks, armament of the cirrus and shape of gravid uterus. Its type species, P. plegadissaakovae sp. n. is described from Plegadis falcinellus L. It was found by Е. О. Saakova and assigned as Paradilepis plegadis nomen nudum because its description was not published according to the criteria of the International Code of Zoological Nomenclature. The additions to the keys of gryporhynchid tapeworms (Bona, 1994) are proposed. The genus Dendrouterina is divided, according to the existing groups “herodiae” and “macrosphincter” distinguished by Bona (1975) into two valid genera, Dendrouterina and Mashonalepis Beverley-Burton, 1960.

The poeciliid species, Poecilia kempkesi Poeser, 2013, was the fourth species of the subgenus Acanthophacelus Eigenmann, 1907 to be described, based on individuals from a single urban anthropized locality close to Paramaribo, Suriname (Poeser, 2013). The description itself lacked any section clearly distinguishing the new species from the remaining species of Poecilia Bloch & Schneider 1801, and in particular from the species of the subgenus Acanthophacelus, type species Poecilia reticulata Peters, 1859. According to Article 13 of the International Code of Zoological Nomenclature (ICZN, 1999) the criteria of availability for a species-group name are:

The chirostyloidean squat lobster genus Gastroptychus Caullery, 1896 is revised and is split into two genera: Gastroptychus sensu stricto (type species, Ptychogaster spinifer A. Milne-Edwards, 1880) and Sternostylus new genus (type species, Ptychogaster formosus Filhol, 1884). Gastroptychus sensu stricto, is restricted to nine species with a sternal plastron, at sternite 3, abruptly demarcated from the preceding sternites (excavated sternum) by a distinct step forming a well-defined transverse or concave anterior margin at the articulation with maxillipeds 3, the maxillipeds 3 widely separated, with the distal parts accommodated in the excavated sternum between the left and right maxillipeds 3 when folded, and the P2–4 dactyli with the terminal spine demarcated by a suture. Sternostylus new genus, represented by 12 species, has the sternite 3 anteriorly bluntly produced medially and steeply sloping anterodorsally to the anterior sternite, with a pair of spines directly behind the anterior margin, the left and right maxillipeds 3 adjacent, and the P2–4 dactyli ending in an indistinctly demarcated corneous spine. The above-mentioned characters of Gastroptychus are consistent with Chirostylidae sensu stricto. Published molecular phylogenies indicate, however, that Sternostylus is the sister group to all the other Chirostylidae, and is designated the type genus of a new family, Sternostylidae.

It has been called to my attention that the generic name Dofleinia, established by McLaughlin and Asakura (2004) for Parapagurodes doederleini (Doflein, 1902), is a junior subjective homonym of Dofleinia Wassilieff, 1908 (Cnidaria: Anthozoa: Actiniidae).  In accordance with Article 60 of the International Code of Zoological Nomenclature (International Commission on Zoological Nomenclature, 1999), I now propose Pagurodofleinia as a replacement name. The type species, Catapagurus doederleini Doflein, 1902, the gender (feminine), and the etymology (named for F. Doflein who first described the type species) remain as given by McLaughlin & Asakura (2004), as does the generic diagnosis.

Ditaxodon taeniatus is a striped, racer-like colubrid snake inhabiting grassland savannas in southern Brazil. This species was described as Philodryas taeniatus by the then curator of the Museum für Naturkunde der Humboldt-Universität zu Berlin (formerly Zoologisches Museum Berlin, ZMB), Wilhelm Peters, from a single specimen collected by Reinhold Hensel in Porto Alegre, Rio Grande do Sul. Peters’ description was published in a paper by Hensel (1868: 331) and, according to the International Code of Zoological Nomenclature (ICZN, 1999: Article 50.1, Recommendation 51E), the correct citation is Ditaxodon taeniatus (Peters in Hensel, 1868). Later, George A. Boulenger (1896: 124) transferred Philodryas taeniatus to the genus Conophis, and Alphonse R. Hoge (1958: 54) created for it the new genus Ditaxodon, which remains monotypic today.

Bicarinellata a new name for Bicarinella Rode, Lieberman, and Rowell, 2003 (Arthopoda, Bradoriida) preoccupied by Bicarinella Waterhouse, 1966 (Mollusca, Gastropoda) and Bicarinella Akopyan, 1976 (Mollusca, Gastropoda)

The One

The genus Bicarinella Rode et al., 2003 was erected for a new hipponicharionid bradoriid species described from the early Cambrian of East Antarctica, characterized by a subtriangular carapace with prominent anterior and posterior lobes developed as two distinctive, sharp ridges (bi = two, carina = ridges). Unfortunately, the name Bicarinella is preoccupied by two different gastropod genera: Bicarinella Waterhouse 1966, a Permian gastropod from New Zealand and Australia, and Bicarinella Akopyan 1976, a gastropod from Late Cretaceous strata of Armenia, Serbia, Romania, Tajikistan, and Egypt (Mennessier, 1994; Banjac, 1998; Pana, 1998). Mennessier (1994) transferred Bicarinella Akopyan, 1976 from its original status as an independent taxon to a subgenus of Pseudomesalia Douvillé 1916, but subsequent workers have continued to consider Bicarinella a valid genus (Pena, 1998; Banjac, 1998). Due to the preoccupation, the bradoriid genus is herein renamed in accordance with the requirement of the International Code of Zoological Nomenclature (1999, article 60). It is also noted here that the one of the two distinct gastropod genera should be renamed. The name Bicarinellata (bi = two, carina = ridges) is proposed as a replacement name for Bicarinella Rode et al., 2003. This name retains the original prefixes to preserve taxonomic stability as much as possible. The type species of Bicarinellata is B. evansi by original designation (Rode et al., 2003).

A New Species

Karagandoceratids are a rare offshoot of the Prionoceratinae, resembling that subfamily in general conch form and sutural ontogeny, but differing by possession of an acute ventral margin and an increasingly trifid ventral lobe. The systematic position of the Karagandoceratidae has been controversial [see Bartzsch and Weyer (1988) for an exhaustive review]. The nominate genus, Karagandoceras Librovitch, 1940 (type species, K. galeatum), possesses a weakly divided ventral lobe which has led authors to refer it to both the Praeglyphioceratina (Ruzhencev, 1960, 1962; Bogoslovsky, 1971; Ruzhencev and Bogoslovskaya, 1978; Bogoslovskaya et al., 1999; Kusina, 2000) and the Goniatitina (Weyer, 1965, 1972; Kullmann, 1981). Discovery of an ancestral karagandoceratid genus, gen. nov. I aff. Karagandoceras Bartzsch and Weyer, 1988, in the early Tournaisian Siphonodella sandbergi conodont Zone in Germany provided clarification on the proximate origin of Karagandoceras and provided a plausible link to the early Tournaisian prionoceratin genus Nicimitoceras Korn, 1993 (type species, Imitoceras subacre Vöhringer, 1960). Bartzsch and Weyer (1988) proposed a karagandoceratid phylogeny beginning with gen. nov. I aff. Karagandoceras in the early Tournaisian, progressing through Karagandoceras in the middle Tournaisian, and culminating with a third, descendent genus, gen. nov. II aff. Karagandoceras (typical species, Karagandoceras bradfordi Manger, 1971), early in the late Tournaisian. Bartzsch and Weyer (1988) elected to leave both the initial and final members of this lineage, gen. nov. I and gen. nov. II aff. Karagandoceras, in open nomenclature pending discovery of more completely preserved material. Discovery of superbly preserved representatives of a new species of gen. nov. II aff. Karagandoceras from the Borden Formation in northeastern Kentucky provides additional sutural and morphological details that support Bartzsch and Weyer's phylogenetic interpretation and makes formal description of this terminal karagandoceratid taxon (herein designated Masonoceras new genus) possible.
