Article Reference Sea Cucumbers of the Comoros Archipelago
Sea cucumbers have been harvested for centuries in the Far East. Overexploitation, coupled with increasing demand has led to local depletion of certain standing stocks. De novo investigation at Grande Comore (one of the four main islands of the Comoros Archipelago) allows reappraisal of local holothuroid biodi- versity. Comparison with neighbouring areas allows extrapolation of holothuroid species richness to the rest of the archipelago. The current exploitation of holothuroids has been documented and there are definite signs of overexploitation. Conservation measures are urgently needed if exploitation of sea cucumbers in this area is to become sustainable in the near future.

Article Reference Taxonomy of the monotypic genus Koehleria Cherbonnier, 1988 (Echinodermata: Holothuroidea: Cucumariidae)
Voucher material recently collected from the 2-Mile Reef at Sodwana Bay (Republic of South Africa), allows the evaluation of the monotypic genus Koehleria Cherbonnier, 1988 and its species K. unica Cherbonnier, 1988 collected from Tuléar (Madagascar). Cherbonnier’s (1988) conclusion, that Koehleria is most related to the also monotypic genus Pseudocolochirus Pearson, 1910 is correct, but the differences between Koehleria and Pseudocolochirus are too small to justify the retention of Koehleria. Koehleria is relegated herein to the synonymy of Pseudocolochirus. Such a step decreases the velocity with which monotypic genera are currently described within the Dendrochirotida.

Article Reference The genus Labidodemas (Holothuriidae:Aspidochirotida) revisited with description of three new species and with re-positioning of Holothuria (Irenothuria) macculochi Deichman, 1958
Prior to the present revision the taxon Labidodemas comprised Labidodemas americanum, L. pertinax, L. rugosum and L. semperianum. An up-to-date re- evaluation of the group proved that at least four additional species need to be assigned to it. Three of these are new to science: one has recently been discovered in the shallow waters of KwaZulu-Natal, Republic of South Africa; one originates from Low Island, Australia, and was erroneously identified as L. semperianum, and one stems from South-West Sulawesi, again erroneously identified as L. semperianum. In addition, Holothuria maccullochi, classified in the monotypic subgenus Irenothuria, and Holothuria proceraspina are assigned to Labidodemas; the former as a valid species and the latter as a synonym of L. semperianum. Annotated taxonomic descriptions, distribution maps and an identification key are given. The new observation that L. americanum possesses Cuvierian tubules suggests that its rank remains at generic level rather than at family level as was recently proposed.

Article Reference The holothurian subgenus Mertensiothuria (Aspidochirotida: Holothuriidae) revisited.
Mertensiothuria is one of the 20 subgenera currently recognized under Holothuria. The diagnosis of the subgenus is amended with new information on the ossicles found in the longitudinal muscles. The number of species of Mertensiothuria considered to be valid at present is six. These species are redescribed on the basis of new material, type and non-type museum material and on re-evaluation of literature. Two of them, Holothuria hilla and Holothuria aphanes, are transferred from the subgenus Thymiosycia to Mertensiothuria. Four species formerly referred to Mertensiothuria are removed; provisionally they are not referred to any of the known subgenera of Holothuria. Full annotated descriptions or (where the type material was not available) references to the literature are given for each species. An identification key is given to the species belonging to the subgenus Mertensiothuria.

Inproceedings Reference Abc Taxa, 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 over 2 000 extant species globally, 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 well-known. The last published review of the southern African Ophiuroidea however was by Clark and 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, which is the nineteenth volume of the series Abc Taxa includes a taxonomic key to all 136 species, and gives key references, distribution 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 and Courtman-Stock (1976) and which have undergone taxonomic revisions since that time (28). This contribution delivers a copiously illustrated overview of the volume and details how it has been diffused in South Africa and beyond.

Article Reference Prospections sur la « villa gallo-romaine du Sart », au lieu-dit La Hamaide, à Hautrage (B).
Hautrage, une commune belge appartenant à l’entité de Saint-Ghislain, se situe dans la partie occidentale de la province du Hainaut. Plusieurs découvertes archéologiques, la plupart anciennes et souvent mal documentées, sont mentionnées sur son territoire1 . 1. Historique des recherches, le site (J. DUFRASNES) La première mention de ce site archéologique apparaît dans HAUBOUDIN 1898, p. 80. L’auteur, un archéologue amateur très actif habitant Stambruges2 , note alors : Villa du Sart.- Un chemin, qui porte encore le nom de chemin d’El Ville3 , indique la Villa du Sart qui est proche. Le cimetière était la nécropole de cette villa4 . Des notes manuscrites datées de janvier 19415 et un inventaire réalisé à l’occasion de l’entrée d’une partie de la collection d’Edmond Haubourdin aux Musées royaux d’Art et d’Histoire de Bruxelles mentionnent du matériel susceptible de provenir de la villa de la Hamaide à Hautrage, c’est-à-dire de la « villa du Sart » (fig. 1). Cependant, aucun des écrits laissés par cet archéologue ne relate qu’il obtint du matériel archéologique de ce site par acquisition, par des fouilles ou des prospections. Edmond Haubourdin ajoute : « Diverticulum.- Le chemin qui traverse le chemin de fer à la station de la Hamaide porte, au cadastre d’Hautrage, le nom de chaussée romaine. Cette chaussée [dont l’actuelle rue des Bats, à 300 mètres à l’est du site, serait un tronçon selon l’auteur ndlr] passait près de la villa et se dirigeait vers Bavay, probablement vers Chièvres, par Villerot, Sirault et Neufmaison, où elle se confondait avec le diverticulum qui venait de Condé par Stambruges. La grande largeur de cette voie de communication accuse son origine romaine »6
