The first report of Apistobranchus Levinsen, 1883 (Family Apistobranchidae) in Antarctica was presented by Hartman (1967). Two species were later described: Apistobranchus glacierae Hartman, 1978 and Apistobranchus gudrunae Hartmann- Schröder & Rosenfeldt, 1988, which differed from A. glacierae mainly by having compound setae. Subsequently, ecological studies in Antarctica have identified both of these species. On the status of Antarctic Apistobranchus, we concluded that there is up to now, only one valid species, A. glacierae. The character ‘compound-setae’ referred for A. gudrunae is in fact simple limbate ones eventually splintered as described for A. glacierae. Other characters, also previously considered as diagnostics for A. gudrunae, did not differ in both species as shown by the observation of several specimens of different sizes and type material of A. glacierae and A. gudrunae. All the reports on the densities of Antarctic apistobranchids, including ours, show that they have higher values in finer sediments of 20 and 40 m depth. The need of additional work, including the rearing of specimens in the laboratory and plankton analysis, is emphasized.

Six of 11 nominal species of Lycodapus, L. australis Norman, L. derjugini Andriashev, L. dermatinus Gilbert, L. fierasfer Gilbert, L. mandibularis Gilbert, and L. parviceps Gilbert, are recognized. Original descriptions and the disintegrated type do not permit adequate diagnosis of L. extensus Gilbert, which we treat as a nomen dubium. The holotype of L. microchir Schmidt must be reexamined before the status of this nominal species can be assessed. We describe L. endemoscotus n.sp. and L. pachysoma n.sp. off the west coast of North America and another population of L. pachysoma from the Antarctic. The species of Lycodapus form two natural groupings. Long gill rakers and a tendency toward fewer preoperculomandibular head pores characterize L. australis, L. derjugini, L. dermatinus, and L. fierasfer. Short gill rakers, single interorbital pore, and more preoperculomandibular pores typify the remaining species of which L. endemoscotus, L. mandibularis, L. pachysoma, and another undescribed species from the Antarctic possess broad, stout rakers. Very reduced rakers indicate L. parviceps as the most differentiated of the short-rakered species. Descriptions, spot distribution maps, synonymies, and illustrations are provided for all named valid species.

A New Species

Callaspidia Dahlbom is an Aspicerinae genus (Hymenoptera: Cynipoidea: Figitidae) with a Holartic distribution. One species, Callaspidia defonscolombei Dahlbom is cited from South America; however, it has probably been introduced. The morphological features needed to differentiate species of Callaspidia are described. Species in this genus possess much intraspecific variability compared with other morphologically homogeneous Aspicerinae genera. Callaspidia originally included 19 species and two subspecies prior to this study. The type material of 16 species of Callaspidia has been studied, but type material from Callaspidia areolata (Kieffer, 1901), C. dichroa Belezin, 1927, C. dufouri spp vitripennis (Kieffer, 1901), C. dusmeti Tavares, 1924, C. fonscolombei spp minima (Kieffer, 1901), C. marshalli (Kieffer, 1901), C. mediterranea Dalla Torre & Kieffer, 1910, and C. rubricrus Dettmer, 1924, is lost or has been destroyed. Out of these 16 studied species, only five are considered valid and are redescribed here. The examination of hundreds of additional specimens supplied by different institutions suggests that there is a general lack of knowledge concerning the intraspecific diversity. A new species is described: Callaspidia dahlbomi Ros-Farré & Pujade-Villar n. sp. A key to the six valid species of Callaspidia is given. All species are illustrated. The status of Figites latreilli Hartig, 1840 is discussed, resulting in Omalaspis latreilli (Hartig) n. comb.

Newly discovered fossils from Eocene rocks of the Quimper Sandstone, Washington, USA, constitute the first reported occurrence of the albuneid genus Lophomastix Benedict, 1904, in the fossil record. Lophomastix and the closely related genus Blepharipoda Randall, 1839, are thought to be basal taxa within the decapod family Albuneidae Stimpson, 1858, based upon possession of primitive trichobranch gill structures. The occurrence of Lophomastix antiqua new species in Eocene deposits indicates that the genus is at least as old as the more derived genus, Albunea Weber, 1795, as would be expected for the basal taxon within the family. Based upon examination of type material, Blepharipoda brucei Rathbun, 1926, is herein removed from that genus and placed within the Paguroidea as Pagurus brucei (Rathbun, 1926) new combination.

The Creation

In July 2014, the international meeting “Burning questions and problems of zoological nomenclature” was held in Linz (Austria). It acknowledged the presence in the current International Code of Zoological Nomenclature of a number of severe problems, and accordingly decided the creation of a new international body, the Linz Zoocode Committee (LZC), in charge of writing the Linz Zoocode, a set of new proposals regarding the terminology, the Principles and Rules of zoological nomenclature. Here we present the first report of the activities of this Committee, covering the period 2014‒2019. It contains the presentation of our work, and the first documents adopted by the Committee: the Preamble and Principles of the Zoocode, the description of its structure and a first instalment of the Zoocode Glossary. The Zoocode regulates the status of zoological nomina and nomenclatural acts (onomatergies). Its aim is to provide an explicit, precise and objective nomenclatural system for the unambiguous and universal naming of all zoological taxa recognised by taxonomists, so that, in the frame of a given classification, the nomen of each taxon is unique and distinct. It relies on a Nomenclatural Process consisting in four main stages: nomenclatural assignment and availability, taxonomic allocation, nomenclatural validity and correctness, and registration of nomina and onomatergies. Whereas the Code currently in force is based on six stated Principles, the Zoocode recognises 17 distinct ones. We here submit these documents to the consideration of the international community of zootaxonomists, in the perspective of the incorporation of these proposals into the next version of the Code.

Diploscapteroides persicus n. sp. is described and illustrated based on morphological, morphometric and molecular data. The new species is mainly characterised by female body length of 469-673 μm, female tail length of 51-99 μm, shape of gubernaculum and spicules and arrangement of male genital papillae. Also, the arrangement of male genital papillae of the new species shows the presence of precloacal papillae, a feature that has not been previously described for the genus. The new species is comparable with all valid species of the genus, namely D. boettgeri, D. brevicauda, D. chitinolabiatus, D. coroniger, D. dacchensis and D. flexuosus, from which the morphological comparisons of the new species with aforementioned species are discussed. Phylogenetic analyses using partial sequences of SSU and LSU rRNA genes were performed for the new species, being the first representative of the genus to be phylogenetically studied using both Bayesian inference (BI) and maximum likelihood (ML) methods, and revealed that D. persicus n. sp. formed a clade with a species of Cephaloboides.

AbstractAlloxysta Förster, 1869 (Hymenoptera: Figitidae) type material of 19 nominal species deposited in the Canadian National Collection of Insects (Ottawa, Ontario, Canada) and the United States National Museum of Natural History (Washington, District of Columbia, United States of America) were studied. Nine species are treated as valid: A. australiae (Ashmead, 1900), A. commensuratus Andrews, 1978, A. japonicus (Ashmead, 1904), A. lachni (Ashmead, 1885), A. longiventris Baker, 1896, A. minuscula Andrews, 1978, A. nothofagi Andrews, 1976, A. vandenboschi Andrews, 1978, and A. xanthopsis (Ashmead, 1896). The following synonymies are established: A. affinis (Baker, 1896) and A. quebeci Andrews, 1978 junior synonyms of A. castanea (Hartig, 1841); A. alaskensis Ashmead, 1902 and A. coniferensis Andrews, 1978 junior synonyms of A. macrophadna (Hartig, 1841); A. bicolor (Baker, 1896) and A. anthracina Andrews, 1978 junior synonyms of A. obscurata (Hartig, 1840); A. dicksoni Andrews, 1978 junior synonym of A. pilipennis (Hartig, 1840); and A. leguminosa (Weld, 1920), A. megourae (Ashmead, 1887), and A. rauchi Andrews, 1978 junior synonyms of A. brevis (Thomson, 1862). The type material of A. schlingeri Andrews, 1978 and A. halli Andrews, 1978 could not be found and we consider them as nomina dubia. Alloxysta vandenboschi Andrews is removed from synonymy with A. obscurata and considered a valid species. Comments on the type material are given. Complete redescriptions and images are presented for the valid species.

The 19Th Century

Franz Xaver Fieber was a leading Hemiptera taxonomist in the 19th century. The recent discovery of his unpublished drawings that go along with the original handwritten manuscript allow a reassessment of species descriptions from this century. In addition, we present an alphabet of Fieber's handwriting. We give an overview on the Cixiidae species he had described and reassess the status of the species names Cixius brachycranus Scott, 1870, Cixius intermedius Scott, 1870, Cixius pinicola Fieber, 1876, Tachycixius venustulus (Germar, 1830) and Tachycixius distinctus (Signoret, 1865). T. venustulus and T. distinctus are regarded as valid species. The synonymy of C. pinicola with T. venustulus is invalidated and C. pinicola is placed in synonymy with T. distinctus.

Pic has contributed most of the descriptions of species and varieties of the genus Astylus Laporte, 1836. However, in some cases, he defined the distinction between taxa on the basis of variable characters. The study of the external morphology and genitalia of the type material of Astylus alboscutellatus Pic,1919a; A. banghaasi Pic, 1902; A. banghaasi var. reichei Pic, 1919a; A. binotatus Pic, 1940; A. elongatior Pic, 1902; A. elongatior var. disjunctus Pic, 1902; A. scalaris Pic, 1919b and A. tucumanensis Pic, 1902, as well collections material, allows to establish new diagnoses and new nomenclatural changes. Following new synonymies are proposed: A. banghaasi Pic, 1902 (= A. banghaasi var. reichei Pic, 1919a n.syn. = A. elongatior Pic, 1902 n.syn. = A. elongatior var. disjunctus Pic, 1902 n.syn.) and A. scalaris Pic, 1919b (= A. binotatus Pic, 1940 n.syn.). The valid species are redescribed.

Written Descriptions

Many valid species can hide buried within prior taxonomic revisions. These need to be examined before the taxonomist embarks on the challenging task of naming new taxa. In this study we re-examine the synonyms complied by Abbott (1960) under Canarium urceus (Linné, 1758), examining each taxon for morphological clarity and distinctiveness. After considering the written descriptions and type material in light of prior revisions, we suggest that there are three valid species buried within the C. urceus synonymy of Abbott. All three species can be differentiated from C. urceus in general form, being less equi-triangulate and lacking the strong shoulder knobbing of that species. In addition, all three species are distinguishable by their distinctive aperture colouration. Canarium urceus possesses a typically black aperture, Canarium anatellum (Duclos, 1844) can be differentiated by its typically uniformly red/orange aperture, while Canarium incisum (Wood, 1828)is recognisable by the typically orange columella and outer lip, and a more triangular form. Strombus ustulatus form laevis Dodge, 1946 is the classical well-known form from the Philippines and elsewhere that is recognisable by its white columella. As the name laevis was preoccupied, we have renamed the species Canarium esculentum nomen novem. We assessed Strombus crassilabrum Anton, 1839 to be a nomen dubium. Further, our revision provides an improved hypothetical framework for the evolution and radiation of this most adaptable and variable of organisms, through increased clarity, and the re-circumscription of hitherto described taxa with distinctive morphotypes and separate biogeographical ranges.
