ABSTRACTThe genus Machaeroprosopus has long been considered invalid because the type specimen of the Late Triassic phytosaur species, M. validus, has been lost. Re-examination of the primary literature regarding the establishment of the Late Triassic phytosaur genus Machaeroprosopus demonstrates that M. buceros is the correct type species, not M. validus. Thus, the genus level name Machaeroprosopus has priority over the genera Pseudopalatus and Arribasuchus and all nominal species should be reassigned. Reassignment of these species to Machaeroprosopus satisfies the requirements of the International Code of Zoological Nomenclature (ICZN) and preserves historical context. The name Pseudopalatinae is retained as the valid clade name for these phytosaurs because its usage falls outside of the ICZN.

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).

Original Publication

The genus Quasimodia Sheard, 1936 belongs to the hyaloidean family Phliantidae, and contains four species inhabiting littoral and sublittoral habitats in Australia (J.L. Barnard 1972; Lowry & Stoddart 2003; Horton et al. 2018; Lowry & Myers 2019). This genus-group name was originally erected for three nominal species—Q. barnardi Sheard, 1936, Q. capricornis Sheard, 1936, and Q. womersleyi Sheard, 1936 (see Sheard 1936), but its type species was not fixed in the original publication. As such the name Quasimodia Sheard, 1936 is not available for nomenclatural purposes (Article 13.3 of the International Code of Zoological Nomenclature [hereafter Code], International Commission on Zoological Nomenclature 1999). Later, J.L. Barnard (1969) selected Q. womersleyi as the type species for this genus-group name, but his action does not validate Quasimodia Sheard, 1936, which remains unavailable, under Article 69 of the Code. J.L. Barnard (1972) again incorrectly considered Quasimodia Sheard, 1936 as an available name. 

“Page priority” does not exist in the Code: Neomegalotomus parvus (Westwood, 1842) has precedence over Neomegalotomus simplex (Westwood, 1842)  (Hemiptera, Heteroptera, Alydidae)

Specific Reason

In a recent paper, Schaefer (2007) considered Neomegalotomus simplex (Westwood, 1842: 18) and Neomegalotomus parvus (Westwood, 1842: 19) (Hemiptera: Alydidae) as subjective synonyms – although no specific reason for this was given, except the following statement, after commenting he had seen both types: “I find that N. parvus and N. simplex are the same species, and synonymize them here” (Schaefer 2007: 320). Nevertheless, Schaefer (2007) explicitly invoked a non-existent rule under the International Code of Zoological Nomenclature (hereafter referred to as the Code) to justify his choice of N. simplex as senior synonym (because both names were published in the same work): “by page priority, Neomegalotomus simplex has seniority over N. parvus” (Schaefer 2007: 320). The above interpretation is wrong according to the Code. There is no “page priority” in any article of the Code. When two or more names, spellings, or nomenclatural acts are published on the same date, priority among them, according to the Code, is given either by date or by First Reviser action, not by page number (Articles 24.2.1 and 24.2.2). The only mention to a “page priority” in the Code is Recommendation 69A.10, in Article 69.4, which deals with fixation of type species. This recommendation (the last one in a rank series of 10) states that “all other things being equal, preference should be given to the nominal species cited first in the work, page or line (‘position preference’).” Nonetheless, it does not deal with seniority of synonyms, homonyms, spellings or nomenclatural acts.

Senior Synonym

The type species and nomenclature are discussed in detail of the genus-group names that have been used, correctly or incorrectly, in combination with species recorded from Portugal. This work strictly adheres to the rules of the International Code of Zoological Nomenclature, in order to promote nomenclatural stability. The contents are strictly nomenclatural as no view is taken on the taxonomic validity or rank of the genus-group names. A total of 171 available names are examined. Evidence is provided in each case for the reasons why the stated nominal species is believed to be the validly designated type species. Many instances were found in the modern literature of type species statements not in compliance with the requirements of the Code. In most cases it is a senior synonym that is stated as type species, instead of the nominal species originally included when the genus was established. That, fortunately, does not cause nomenclatural instability but should be corrected. In three cases where nomenclatural stability is threatened, Anisoplia Schönherr, 1817, Phyllopertha Stephens, 1830, and Scarabaeus Linnaeus, 1758, it is suggested that prevailing usage should be maintained until a case is made to the International Commission on Zoological Nomenclature and a ruling is published.

Fourth Species

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 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.

Pagurodofleinia, a replacement generic name for Dofleinia McLaughlin & Asakura, 2004 (Crustacea: Decapoda),  preoccupied by Dofleinia Wassilieff, 1908 (Cnidaria: Anthozoa)

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.

An overlooked De Geer name, Nemotelus flavipes De Geer, 1776 has been identified as synonymous with Pandivirilia eximia (Meigen, 1820), a name in use for a species of stiletto fly (Diptera: Therevidae). The type specimen has been lost, and this synonymy is based on the original description and associated figures provided by De Geer. Nemotelus flavipes De Geer, 1776, is a nomen oblitum and Thereva eximia Meigen, 1820 is a herein recognized as a nomen protectum in accordance with Article 23.9.2 of the International Code of Zoological Nomenclature, which maintains prevailing name usage for the species Pandivirilia eximia (Meigen, 1820).

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).

Species Being

The Galápagos pink land iguana, Conolophus marthae Gentile & Snell, 2009 (Squamata: Iguanidae) is the latest example of a species being described without the proper deposition of a preserved onomatophore (name-bearing type specimen) in a taxonomic collection. Differently from other recent similar descriptions, the holotype of Conolophus marthae was marked with a Passive Integrated Transponder, allegedly allowing it to be tracked and found after its death, when it would be deposited at the Governmental Galápagos collection. Although apparently fulfilling the criteria of the International Code of Zoological Nomenclature, I here argue that this practice should not be followed and that the International Commission on Zoological Nomenclature should urgently act to standardize criteria that should be met by those describing species found at the brink of extinction.
