From 2004 to 2012, ten multidisciplinary oceanographic surveys were conducted along the coast of Northwest Africa, between the Strait of Gibraltar and the northern border of Sierra Leone. A total of five species of Euryalida Lamarck, 1816 belonging to three families were captured at 29 of the 1298 stations sampled in the area. Among them, Astrodendrum juancarlosi sp. nov. is described and figured in this paper. Ophiocreas oedipus Lyman, 1879 is recorded for the first time on West African continental margin and Gorgonocephalus pustulatum (H.L. Clark, 1916), an Indo-Pacific species only known from South African coast in the Atlantic, is reported off Guinea-Bissau, greatly extending to the North its Atlantic distribution. In addition, Asteroschema inornatum Koehler, 1906, a northeast Atlantic species, is recorded for the first time in African waters, off Western Sahara, extending its range of distribution to the south. Our data also extend the bathymetric distribution of A. inornatum to shallower waters and of G. pustulatum to deeper waters. The association of some euryalids with certain species of pennatulaceans and gorgonians is also described.

During mycological explorations, a new smooth spored species, Inocybe subhimalayanensis Razzaq, Naseer & Khalid sp. nov. was collected from moist temperate sub-Himalayan region, Pakistan. Phylogeny of ITS and LSU regions of nrDNA, and morphoanatomical data make it distinct from other known species of the genus. The taxon is characterized by: a yellowish orange to brown pileus with prominent fibrillose, prominent umbo; ellipsoid to amygdaliform smooth larger basidiospores (8.4‒)8.6‒12.2(‒12.6) × (4.9‒)5.1‒7.1(‒7.3) µm; and lack of velipellis. Molecular phylogenetic analyses further support the recognition of the new species.

Between 2019 and 2021, samplings were carried out from seashores in Italy and Croatia, where specimens were found morphologically similar to the species of the Enchytraeus albidus complex. The taxon Enchytraeus albidus was recently divided into a number of separate species, and the new Italian and Croatian specimens of Enchytraeus proved to be three additional species, all new to science, based on the results of morphological and molecular studies. In this paper, we present the description of these new species, namely Enchytraeus adrianensis sp. nov., Enchytraeus andrasi sp. nov. and Enchytraeus andrasiformis sp. nov., and provide additional morphological data and new reference sequences for E. albidus s. str., E. krumbachi, E. irregularis and further unidentified specimens that belong to the E. albidus group collected formerly from Hungary, Korea, Svalbard and Kerguelen Islands.

An annotated catalogue of the type specimens of the family Cerambycidae Latreille, 1802 (Coleoptera) housed at the Zoological Museum of Hamburg (ZMH), Leibniz Institute for the Analysis of Biodiversity Change (LIB) is provided: one holotype and nine secondary types were found deposited at the ZHM. A list of the primary types lost during the bombardment in the Second World War is also provided, including types of 103 names, 14 of Cerambycinae, 87 of Lamiinae, and two of Prioninae. In addition, we report secondary types that have been found, corresponding to names of subspecific rank and unavailable names with infrasubspecific rank.

In order to provide a reassessment of the Neotropical genus Pseudonannolene Silvestri, 1895, a cladistic analysis, biogeographic analysis, and taxonomic review were conducted in the present work. For the cladistic approach, 91 morphological characters were scored for 53 terminals as the ingroup and 10 as the outgroup. Three synapomorphies support the monophyly of the genus: presence of a longitudinal suture on the promentum, penial bases partially fused, and the internal branch of the gonopods surrounding the telopodite; and two homoplastic transformations: the lateral lobe of the collum densely striated and setae present up to the apical portion of the prefemoral process on the first leg-pair of males. The genus Pseudonannolene is recovered as sister-group of Epinannolene Brölemann, 1903 (Pseudonannoleninae). A total of 226 occurrence points were recorded for Pseudonannolene, with the majority of records from the Chacoan subregion, composed by Araucaria Forest, Atlantic, and Parana Forest provinces. The biogeographical searches using the Geographically explicit Event Model recovered two biogeographic reconstructions (cost of 79 000), with the vicariance events occurring more frequently in the deep clades, whereas sympatry and points of sympatry occurred in more inclusive clades. The first reconstruction recovered four vicariances, 13 sympatries, 4 points of sympatry, and 21 founder events, and the second reconstruction recovered four vicariances, 12–13 sympatries, 4–5 points of sympatry, and 21 founder events. The genus Pseudonannolene comprises 56 species, including 8 new species herein described: P. alata sp. nov., P. aurea sp. nov., P. bucculenta sp. nov., P. curvata sp. nov., P. granulata sp. nov., P. insularis sp. nov., P. morettii sp. nov., and P. nicolau sp. nov.; P. brevis Silvestri, 1902 and P. rugosetta Silvestri, 1897 are regarded as species inquirendae; a neotype of P. alegrensis Silvestri, 1897 is here proposed with male described for the first time. The following taxa are synonymized: P. canastra Gallo & Bichuette, 2020 and P. saguassu Iniesta & Ferreira, 2013 with P. ambuatinga Iniesta & Ferreira, 2013; P. marconii Iniesta & Ferreira, 2013 with P. longicornis (Porat, 1888); P. chaimowiczi Fontanetti, 1996, P. gogo Iniesta & Ferreira, 2013, P. rosineii Iniesta & Ferreira, 2014, P. taboa Iniesta & Ferreira, 2014, and P. longissima Iniesta & Ferreira, 2014 with P. microzoporus Mauriès, 1987; P. tricolor gracilis Brölemann, 1902 and P. tricolor rugosus Schubart, 1945 with P. tricolor Brölemann, 1902; P. auguralis Silvestri, 1902 with P. rocana Silvestri, 1902; and P. abbreviata Silvestri, 1902 with P. typica Silvestri, 1895. P. inops Brölemann, 1929 is proposed here as new status from P. bovei inops. A dichotomous identification key is presented to facilitate the species identification.
