Field guide to the brittle and basket stars (Echinodermata: Ophiuroidea) of South Africa
-
Brittle and basket stars (ophiuroids) are one of five extant classes of the phylum Echinodermata and have a fossil record dating back almost 500 million years to the Early Ordovician. Today, they remain diverse and widespread, with over 260 described genera and 2,077 extant species globally (Stöhr et al. 2018), more than any other class of echinoderm. Ophiuroid species are found across all marine habitats from the intertidal shore to the abyss. In southern Africa, the ophiuroid fauna has been studied extensively by a number of authors and is relatively wellknown. The last published review of the southern African Ophiuroidea however was by Clark & Courtman-Stock in 1976. It included 101 species reported from within the boundaries of South Africa. In the 40 years since that publication the number of species has risen to 136. This identification guide includes a taxonomic key to all 136 species, and gives key references, istribution maps, diagnoses, scaled photographs (where possible), and a synthesis of known ecological and depth information for each. The guide is designed to be comprehensive, well illustrated and easy to use for both naturalists and professional biologists. Taxonomic terms, morphological characteristics and technical expressions are defined and described in detail, with illustrations to clarify some aspects of the terminology. A checklist of all species in the region is also included, and indicates which species are endemic (33), for which we report significant range extensions (23), which have been recorded as new to the South African fauna (28) since the previous monograph of Clark & Courtman-Stock (1976) and which have undergone taxonomic revisions since that time (28).

First Atlantic record of the rare infaunal shrimp Salmoneus erasimorum Dworschak, Abed-Navandi & Anker, 2000 (Malacostraca: Decapoda: Alpheidae)
-
The rare symbiotic alpheid shrimp Salmoneus erasimorum Dworschak, Abed-Navandi & Anker, 2000 was previously known from a single specimen collected with a suction pump on the Croatian coast in the Adriatic Sea, together with its host, the ghost shrimp, Gilvossius tyrrhenus (Petagna, 1792). A second record of S. erasimorum is presented here, with a diagnosis and the first colour photographs, based on a single specimen collected in northern Brittany, France, also with a suction pump, but without its host. This is also the first record of the species on the European coast of the Atlantic Ocean. An annotated list and a key to the species of Salmoneus currently known from the eastern Atlantic and the Mediterranean Sea are provided.

First detailed study of the Belgian Eocene sea turtle ‘Oligochelone rupeliensis’
-
In 1909, the famous palaeontologist Louis Dollo announced, in a paper about the Belgian fossil vertebrates, a new Oligocene (Rupelian) genus and species of sea turtle, ‘Oligochelone rupeliensis’. He indicated that it was established for a specimen that preserved the complete carapace and several appendicular bones, being characterized as “a typical marine turtle”. No further information, but neither photographs or drawings, were provided by him. He planned to publish the study of this species in the future, but this did not happen. Only a schematic drawing of the plastron of that specimen, as well as a photograph of a tibia attributed to this taxon without justification, were presented, by another author, seventy years later. The first-hand study of the specimen considered by Dollo allows us to observe that it does not preserve any tibia, so that attribution cannot be supported. Therefore, except for that imprecise drawing of the plastron published more than four decades ago, no additional information was available so far. In fact, ‘Oligochelone rupeliensis’ was recognized as a nomen nudum. After a preliminary analysis of the specimen considered by Dollo, one of us (APG) and other collaborators recently indicated, without justification, that, although ‘Oligochelone rupeliensis’ could be closely related to the Eochelone representatives, it differs from all defined members of Cheloniidae. Therefore, we point out that a detailed anatomical study of this form, as well as its comparison with other species, would be necessary to propose, for the first time, a diagnosis, if its specific validity can be confirmed. Taking this into account, that partial skeleton has been analyzed in detail by us. To improve the comparative framework, both the type material and additional individuals from all Eocene and Oligocene cheloniid taxa recognized for the Belgian record have also been analyzed first-hand. The preliminary results are presented here.

First inventory of Ants (Hymenoptera: Formicidae) with detection of potentially invasive species in National Park of Ehotilés islands, Côte d’Ivoire
-
Estuarine and wetland ecosystems are becoming increasingly altered by the concentration of human population near the coastline. A major threat to biodiversity related to this is the introduction of invasive alien species. This is particularly the case for isolated ecosystems like islands where the invasion of non-native species is often harmful. The National Park of Ehotilés Islands is an archipelago of 6 islands and a RAMSAR site subjected to disturbances, namely agriculture, illegal fisheries, and tourism. These factors often act as an accelerator for the introduction of invasive species. However, there is a lack of research on insects, specifically ants, on these islands. This study aimed to inventory the present ant fauna and estimate the vulnerability to tramp and potential invasive ant species. Ants were collected using Winkler, pitfall, and funnel traps on five islands. In total, 76 ant species were recorded. These species are distributed into 20 genera and five subfamilies: Dolichoderinae (5 species), Formicinae (11 species), Myrmicinae (49 species), Ponerinae (11 species) and Proceratiinae (1 species). We also detected two tramp and potentially invasive species: the ghost ant Tapinoma melanocephalum and the big-headed ant Pheidole megacephala. Ant communities are dominated by six species, namely Odontomachus troglodytes, Oecophylla longinoda, Nylanderia lepida, Pheidole sp.2, Monomorium invidium, and the invasive ghost ant Tapinoma melanocephalum. This work is the first to inventory ants on the Islands of Ehotilés National Park and may serve as a basis for conservation decisions as it demonstrates that this park is not spared from the introduction of invasive ant species.
