This electron microscopy study of the materials from ultraoligotrophic lake Elgygytgyn (Chukotka) revealed variability of morphological features in Hannaea arcus var. arcus and H. arcus var. recta. An emended diagnosis for H. arcus var. arcus is presented, and a new combination in specific rank is published: H. inaequidentata (Lagerstedt) Genkal et Kharitonov (= H. arcus var. recta).

AbstractThree new species of Cyphaspides are proposed: C. ammari, C. nicoleae, and C. pankowskiorum. These species are based on specimens obtained from Middle Devonian (Eifelian) strata of the Bou Tchrafine Group, near Erfoud, in the Province of Errachidia, southeastern Morocco. The present contribution enhances our knowledge of Cyphaspides by providing details of three new species that are based on well-preserved, complete, and articulated types. The genus Cyphaspides is discussed, and an emended diagnosis is provided. The paleobiogeography, ontogeny, and relationships of the genus are discussed.UUID: http://zoobank.org/4a7aab8f-8c8e-4498-9cc2-6f8c69b85213

Morphological and molecular characterisation of Aporcelaimellus simplex (Thorne & Swanger, 1936) Loof & Coomans, 1970 and a new concept for Aporcella Andrássy, 2002 (Dorylaimida: Aporcelaimidae)

Emended Diagnosis

This contribution presents a study of Iberian and Californian populations of Aporcelaimellus simplex, including morphological, morphometric and molecular data. The species is characterised and distinguished by its lip region offset by an expansion, pars refringens vaginae absent, and conical tail with a small but distinct hyaline terminal portion. No significant difference exists between American and European populations. Molecular data and the derived evolutionary tree show a topology in which this species forms a well-supported group with members of Discolaiminae, far from other representatives of Aporcelaimellus. Putting special emphasis in the absence of pars refringens vaginae, A. simplex is transferred to the genus Aporcella. The taxonomy of this genus is revised in depth, with the proposal of an emended diagnosis, the provision of a list of 13 valid species (mostly new combinations from Aporcelaimellus) as well as a key to their identification and a compendium of their main morphometrics. Aporcella debruinae sp. n. is proposed for Aporcelaimellus papillatus apud de Bruin & Heyns, 1992.

Emended Diagnosis

Five new species of Oncholaimellus are described. They were found in macrofauna samples from the continental shelf in the Potiguar Basin, north-east Brazil. Cuticular pores with a sclerotized outline associated with a gland were observed in some species. Oncholaimellus multiporus sp. nov. is differentiated from other species by the presence of cuticular pores of different sizes; the smaller pores are abundant and give an appearance of ornamentation. Oncholaimellus intersexus sp. nov. and O. distortus sp. nov. are similar, but differ in the size of the external labial and cephalic setae compared to the corresponding diameter, the presence of the cuticular pores and the tail shape. Oncholaimellus paulus sp. nov. and O. sineporus sp. nov. are similar, although features such as the external labial and cephalic setae size compared to the corresponding diameter and the cuticular pores differentiate between them.

Taxonomic status of the genus Alonopsis was clarified by the morphological study and cladistic analysis. Morphology of both valid species, A. elongata (Sars, 1861) and A. aureolata Doolitle, 1912, was investigated. So far, generic status of the group was questioned, some authors treated Alonopsis as a part of the genus Acroperus. Our data confirm independent status of Alonopsis, and emended diagnosis of the genus is provided. According to our analysis, Acroperus and Alonopsis are the sister-groups of a monophyletic clade, each having their own autapomorphies. Both genera belong to a well-defined group of Aloninae (named here as Arthrocauda-group), which is characterized by the presence of well-developed abdominal joint and elongated narrow postabdomen. There are two parallel clades within the group, one formed by Acroperus and Alonopsis, other by Parakozhowia, Kozhowia and Camptocercus. According to our analysis, these branches have numerous homoplasies, the most significant of them is the independent appearance of the head keel in two most successful genera, Acroperus and Camptocercus.

Abstract The genus Galea Meyen, 1833 includes at least five species of terrestrial, diurnal and herbivorous cavies that occupy grasslands and rocky scrub areas at both high and low elevations in South America. According to the available molecular and morphological data, Galea comes Thomas, 1919 is restricted to highland areas above 2000 m in southern Bolivia and northwestern Argentina. Its distributional range as well as its morphological distinctiveness from other closely related species (Galea leucoblephara and Galea musteloides) is poorly documented. Using both qualitative and quantitative morphological traits, we provided an emended diagnosis for G. comes. In addition, we added six new locality records to its known distribution.

Microconnus Franz, previously treated as a subgenus of Euconnus Thomson, is placed as a subgenus of Napoconnus Franz. Morphological structures of all species included in Microconnus are reviewed and illustrated, and Euconnus canaimanus Franz, Euconnus conulus Franz, and Euconnus janauari O’Keefe are placed as members of Napoconnus (Microconnus), while Euconnus (Microconnus) fulgurans Franz is placed in Euconnus (incertae sedis) (near Napochus Thomson). Emended diagnosis of Napoconnus and a key to identify its subgenera are given.
