Title: Nomenclatural and taxonomic notes on the fossil pollen genus Sparganiaceaepollenites Thiergart 1937
The nomenclature and status of the fossil-genus Sparganiaceaepollenites Thiergart 1937 and several of its species are problematic. We confirm the status of the genus and provide an emended description for it to accommodate new characters that were recently described in some species. We note that (i) the name Sparganiaceaepollenites microreticulatus Grabowska and Wa?y?ska 2009 from the Miocene of Poland is illegitimate according to the rules of the International Code of Nomenclature for algae, fungi, and plants, as a later homonym of Sparganiaceaepollenites microreticulatus Kar and Jain 1981 from the Miocene of India; (ii) the name Sparganiaceaepollenites reticulatus Samant et al. 2022 from the Maastrichtian of India is illegitimate as a later homonym of Sparganiaceaepollenites reticulatus Doktorowicz-Hrebnicka 1960 ex Krutzsch and Vanhoorne 1977 from the Miocene of Poland; and (iii) the name Sparganiaceaepollenites annulatus Thakre et al. 2024 from the Danian of India is illegitimate as a later homonym of Sparganiaceaepollenites annulatus De Benedetti 2023 from the Maastrichtian?Danian of Argentina. We propose the new names (i) Sparganiaceaepollenites oczkowicensis nom. nov. subst. pro Sparganiaceaepollenites microreticulatus Grabowska and Wa?y?ska; and (ii) Sparganiaceaepollenites intertrappeansis nom. nov. subst. pro S. reticulatus Samant et al. (an emended description is provided). Additionally, Sparganiaceaepollenites annulatus Thakre et al. is considered a heterotypic synonym of Sparganiaceaepollenites intertrappeansis nom. nov.  more » « less

    Abstract  The Puerto Rican Tody’s scientific name Todus mexicanus prompts the question of how an endemic Puerto Rican species acquired such a confusingly inappropriate name. Here we address the nomenclatural history of this species to address how and when this misnomer arose, and we use this case study to discuss the pros and cons of changing scientific names. We argue that a variety of circumstances warrant changing mexicanus to borinquensis, despite strong opposition based on International Commission on Zoological Nomenclature rules discouraging changes of toponyms (names based on geographical locations). We discuss several alternatives for the change, emphasizing the potential role of Puerto Ricans. Keywords  conservation, International Commission on Zoological Nomenclature, Latin names, nomenclatural history, Puerto Rican Tody, Todidae, Todus mexicanus Resumen  El San Pedrito de Puerto Rico (Todus mexicanus): ¿Qué hay en un nombre? • El nombre científico del San Pedrito de Puerto Rico, Todus mexicanus, plantea la pregunta de cómo una especie endémica de Puerto Rico adquirió un nombre tan confusamente inapropiado. Aquí abordamos la historia nomenclatural de esta especie para entender cómo y cuándo surgió este error de denominación, y utilizamos este estudio de caso para discutir los pros y los contras de cambiar los nombres científicos. Argumentamos que una variedad de circunstancias justifican cambiar mexicanus a borinquensis, a pesar de la fuerte oposición basada en las reglas de la Comisión Internacional de Nomenclatura Zoológica que desaconsejan los cambios de topónimos (nombres basados en ubicaciones geográficas). Discutimos varias alternativas para el cambio, destacando el papel potencial de los puertorriqueños.

    A new avian chewing louse genus Apomyrsidea gen. nov. is described based on species parasitizing birds in the family Formicariidae. Diagnostic characteristics and phylogenetic analyses were used to evaluate and confirm the generic status and merit its recognition as unique and different from Myrsidea Waterston, 1915. Three species previously belonging to the genus Myrsidea are placed in the new genus Apomyrsidea gen. nov. and are discussed: Apomyrsidea circumsternata (Valim & Weckstein, 2013) gen. et comb. nov., Apomyrsidea isacantha (Valim & Weckstein, 2013) gen. et comb. nov. and Apomyrsidea klimesi (Sychra in Sychra et al., 2006) gen. et comb. nov.

    A new species of the genus Ocnodes is described (O. kruegeri spec. nov.) from Namaqualand, southern Africa. Moreover, an update of the recently published catalogue (Kaminski et al., 2019a) of the tribe Sepidiini is provided. This includes discovery of two nomenclatural duplications and inclusion of nine previously omitted species. The following new combinations are proposed (both species transferred from Psammodes): Ocnodes badeni (Haag-Rutenberg, 1871) and Ocnodes damarinus (Péringuey, 1904). Trachynotus kruegeri nom. nov. is introduced for Trachynotus vicinus Péringuey, 1886 to avoid homonymy with Trachynotus vicinus (Haag-Rutenberg, 1871).

    The genus name Mezammira, attributed to Fieber 1876, was recently proposed to classify several Palaearctic cicada species by Gogala, Puissant & Trilar (2017). The availability of the genus name Mezammira is discussed. Following the rules of the International Code of Zoological Nomenclature, Mezammira cannot be used as an available name. The genus name Oligoglena Horváth, 1912 status revised is proposed as a substitute name. The following new combinations are recognized: Oligoglena carayoni (Boulard, 1982) comb.nov., Oligoglena filoti (Gogala & Trilar, 2017) comb.nov., Oligoglena flaveola (Brullé, 1833) comb.nov., Oligoglena goumenissa (Gogala, Drosopoulos & Trilar, 2012) comb.nov., Oligoglena iphigenia (Emeljanov, 1996) comb.nov., Oligoglena parvula (Fieber, 1876) comb.nov., Oligoglena popovi (Emeljanov, 1996) comb.nov., Oligoglena sakisi (Gogala & Trilar, 2017) comb.nov., Oligoglena sibilatrix (Horváth, 1901) comb.nov., Oligoglena tibialis (Panzer, 1798), Oligoglena turcica (Schedl, 2001) comb.nov.

    The echinoid genus Tetrapygus was initially described by L. Agassiz (1841) based on a single species, Tetrapygus niger Molina, 1782. Since the extensive work conducted by Mortensen (1935), Tetrapygus has received limited taxonomic attention over the past century. Recent discoveries of new fossil species of Arbacia Gray, 1835 from the upper Pliocene of northern Chile revealed striking morphological similarities between the two distinct Arbaciidae genera Arbacia and Tetrapygus. These findings compelled new investigations to evaluate the taxonomic status of these genera. Based on molecular mitochondrial (COI), nuclear (28S), and morphological evidence, Tetrapygus niger is here recovered as the sister species to Arbacia dufresnii, both species forming a clade within the phylogeny of South American species of Arbacia. Consequently, the diagnosis and description of Tetrapygus niger are here revised, and the species is reattributed to Arbacia, as previously proposed by A. Agassiz in Agassiz & Desor (1846) under the species name Arbacia nigra. An emended diagnosis of Arbacia is also proposed in light of these new findings.
