It is proposed that Agrobacterium radiobacter has priority as the earlier heterotypic (subjective) synonym when it is united with Agrobacterium tumefaciens. The nomenclatural status of A. tumefaciens as a later heterotypic synonym of the united species is not lost and it remains the type species of the genus. Request for an Opinion.

Original Type

The original type strains of Agrobacterium radiobacter and Agrobacterium tumefaciens recorded in the eighth edition of Bergey’s Manual of Determinative Bacteriology published in 1974 were NCIB 9042T and ATCC 4720T, respectively. However, in the list of the valid names of bacteria compiled in 1980, both strains were changed, A. radiobacter NCIB 9042T to ATCC 19358T and A. tumefaciens ATCC 4720T to ATCC 23308T. These changes were unjustified, particularly in the case of A. tumefaciens whose type strain was replaced by another strain from the same collection, although the original type strain ATCC 4720T was never lost and it is currently available in several culture collections. Therefore, we request that the type strain of A. tumefaciens be corrected from ATCC 23308T to ATCC 4720T.

Abstract Bryozoans with calcified frontal shields formed by the fusion of costae, collectively constituting a spinocyst, are traditionally assigned to the family Cribrilinidae. Today, this family is regarded as nonmonophyletic. In the Argentine Cenozoic, cribrilinids were until recently represented by only two fossil species from the Paleocene of Patagonia. This study describes the first fossil representatives of Jolietina and Parafigularia: J. victoria n. sp. and P. pigafettai n. sp., respectively. A fossil species of Figularia, F. elcanoi n. sp., is also described. The material comes from the early Miocene of the Monte León and Chenque formations (Patagonia, Argentina). For comparison, we also provide redescriptions of the remaining extant species of Jolietina: J. latimarginata (Busk, 1884) and J. pulchra Canu and Bassler, 1928a. The systematic position of some species previously assigned to Figularia is here discussed. Costafigularia n. gen. is erected, with Figularia pulcherrima Tilbrook, Hayward, and Gordon, 2001 as type species. Two species previously assigned to Figularia are here transferred to Costafigularia, resulting in C. jucunda n. comb. and C. tahitiensis n. comb. One species of Figularia is reassigned to Vitrimurella, resulting in V. ampla n. comb. The family Vitrimurellidae is here reassigned to the superfamily Cribrilinoidea. The subgenus Juxtacribrilina is elevated to genus rank. Inferusia is regarded as a subjective synonym of Parafigularia. Parafigularia darwini Moyano, 2011 is synonymized with I. taylori Kuklinski and Barnes, 2009, resulting in Parafigularia taylori n. comb. Morphological data suggest that these genera comprise different lineages, and a discussion on the disparities among cribrilinid (sensu lato) spinocysts is provided.

The new Ordovician palaeotaxodont family Nucularcidae and the new genus Nucularca are described. Included in Nucularca are four previously described species that have taxodont dentition: N. cingulata (Ulrich) (the type species), N. pectunculoides (Hall), N. lorrainensis (Foerste), and N. gorensis (Foerste). All four species are of Late Ordovician (Cincinnatian Katian) age and occur in eastern Canada and the northeastern USA. Ctenodonta borealis Foerste is regarded as a subjective synonym of Nucularca lorrainensis. No new species names are proposed. The Nucularcidae includes the genera Nucularca and Sthenodonta Pojeta and Gilbert-Tomlinson (1977). Sthenodonta occurs in central Australia in rocks of Middle Ordovician (Darriwilian) age. The 12 family group names previously proposed for Ordovician palaeotaxodonts having taxodont dentition are reviewed and evaluated in the Appendix.

ABSTRACTThe systematics of parts of the Odontopleuridae are revised using character analyses tracing homologous structures, and a computerised cladistic analysis. The choice of outgroup is shown to affect the result of the analysis. Several synapomorphies place Selenopeltis, the type genus of the Selenopeltinae Hawle & Corda, 1847 as sister genus to Dicranurus. The latter's close relationship to Miraspis, type genus of the Miraspidinae Richter & Richter, 1917 is confirmed. The Selenopeltinae therefore becomes a senior subjective synonym of the Miraspidinae. The Selenopeltinae includes about 90 of the over 380 named odontopleurid species known to date (excluding accepted synonyms). The Ceratocephalinae is recognised, including about 30 species. The paired, large pygidial border spines present in most odontopleurids are in some species not homologous, and a falsifiable hypothesis is proposed for the homology of the ‘true major border spines’. This structure is the posterior pleural spine of the tenth postcephalic segment in selenopeltines, ceratocephalines and odontopleurines, and in acidaspidines and apianurines it is the serially homologous spine of the eleventh postcephalic segment. The spine belongs to the first pygidial segment in all taxa except ceratocephalines, where it is on the last thoracic segment. The homology in selenopeltines of the progressive restructuring of the cheek border is reviewed, explaining the supramarginal appearance of the genal spine. The presence and homology of the sublobation of L1 in odontopleurids is discussed, and it may be homologous with the sublobation in lichids. The strongly differentiated thoracic segmental lengths (exsag.), with maximum length reached in the anterior part of thorax, and the much reduced length of the posterior segments, are aspects of a single character-complex, uniquely derived within the Selenopeltinae. The ontogenetic origin of the anterior and posterior pleural spines is reviewed. The presence in Ceratocephala of two instars in one meraspid degree is discussed. A cladistic analysis of selenopeltine and ceratocephaline genera does not entirely resolve the topology of the phylogenetic tree of these taxa, but it confirms Selenopeltis as sister taxon to Dicranurus. These two genera belong in a clade also including Miraspis, Selenopeltoides, and Ceratonurus. Two new genera are erected, Ceratocara and Archaeopleura, the latter with type species A. kazakhensis sp. nov.

The systematic position of Aegeria montis Leech, 1889 and Zhuosesia zhuoxiana Yang, 1977 is discussed. Having studied newly collected material, we transfer A. montis to the genus Chamaesphecia Spuler, 1910, subgenus Chamaesphecia s. str. The male of this species and its genitalia are illustrated for the first time. The host-plant of its larvae is assumed to be a species of Euphorbia (Euphorbiaceae).        Zhuosesia Yang, 1977, syn. nov., is shown to be a junior subjective synonym of Chamaesphecia Spuler, 1910 with the new combination of its type species, Chamaesphecia zhuoxiana (Yang, 1977), comb. nov.

The soft scale insect genus Scythia (Hemiptera: Coccomorpha: Coccidae) was established by Kiritchenko (1938) with the type species Scythia craniumequinum Kiritchenko, 1938 from Ukraine. Later, Borchsenius (1957) placed Mohelnia Šulc, 1941 (type species: Mohelnia festuceti Šulc, 1941) as a junior subjective synonym of Scythia Kiritchenko, 1938, and proposed new combination: Scythia festuceti (Šulc, 1941). Ben-Dov (1993) followed Borchsenius (1957) in treating Mohelnia as a junior synonym of Scythia.

Subjective Synonym

The fossil record of the burrowing lobster Axius is reviewed. A diagnosis based on the characters with preservation potential is supplied. Plioaxius lineadactylus Fraaije et al., 2011, from the Pliocene of Belgium and the Netherlands is considered congeneric with the type species of Axius. As a consequence, Plioaxius is considered a junior subjective synonym of Axius. A newly described species, Axius hofstedtae from the late Oligocene of Denmark is considered the oldest unequivocal representative of Axius. Both fossil species, A. hofstedtae n. sp. and A. lineadactylus n. comb., share numerous morphological characters with extant Axius stirhynchus. Scarcity of the Cenozoic Axiidae is ascribed to lack of study of the fossil record of this group rather than to low fossilization potential of its representatives. A preliminary scenario of the migration of Axius based on the scarce fossil record suggests the origin in the Western Tethys and subsequent dispersal westward into the West Atlantic and eastward into the West Pacific.

An overview of the taxa of Rhinorhynchinae (Nemonychidae) is presented. A phylogenetic analysis of the 19 extant genera of the Rhinorhynchinae and one fossil genus from the Lower Cretaceous (Cratomacer Zherikhin & Gratshev), based on 29 characters of adults, larvae and host plant associations, shows three monophyletic groups, treated as tribes (Rhinorhynchini, Mecomacerini and Rhynchitomacerini). Primitive associations are unknown for Rhinorhynchinae and early host use diversification included associations with Ranunculaceae (Nemonyx Redtenbacher), Pinaceae (Cimberis Gozis), Nothofagaceae (Rhynchitomacerini) and Podocarpaceae (Rhinorhynchini). While Mecomacerini diversified on Araucariaceae, within Rhinorhynchini there was a single reversal to Araucariaceae and a shift in Atopomacer Kuschel to Pinaceae. Placement of Cratomacer into Mecomacerini is consistent with geological and molecular data that suggest gymnosperms may have been the primitive hosts for the family. Three new genera are described in Rhinorhynchinae: Araucomacer, gen. nov. (type species A. hirticeps Kuschel) from Chile, Idiomacer, gen. nov. (type species I. basicornis, sp. nov.) from New Caledonia, and Zimmiellus, gen. nov. (type species Z. fronto, sp. nov.) from Queensland, Australia, while Stenomacer Kuschel, stat. nov. from Chile is reinstated from synonymy. Seven species are described as new: Atopomacer grandifurca, sp. nov. from Costa Rica and Panama, A. obrieni, sp. nov. from Mexico, A. panamensis, sp. nov. from Panama, A. pini, sp. nov. from Mexico, A. podocarpi, sp. nov. from Venezuela, Basiliogeus dracrycarpi, sp. nov. from western New Guinea and B. inops, sp. nov. from Queensland. Rhynchitomacer rufus Kuschel is a new junior subjective synonym of R. nigritus Kuschel, syn. nov., R. viridulus Kuschel is a new junior subjective synonym of R. flavus Voss, syn. nov. and Stenomacer fuscus Kuschel is a new junior subjective synonym of S. vernus Kuschel, syn. nov. Keys to genera of Rhinorhynchinae and to species of Atopomacer, Rhynchitomacer and Stenomacer are included. Diagnoses of the three extant subfamilies of Nemonychidae are included.
