Paul Philippe Sanguin de Jossigny était un militaire qui commença sa carrière à l'Isle de France (aujourd'hui île Maurice) comme aide de camp du gouverneur et la termina comme capitaine et ingénieur, avant de rentrer à regret à Paris. Sa renommée est fondée uniquement sur son oeuvre de dessinateur pour Philibert Commerson ; après la mort de celui-ci il apporta au futur Muséum d'Histoire naturelle de Paris les collections et les manuscrits du voyageur naturaliste. Parmi ces documents figuraient plus d'un millier de dessins exécutés par Jossigny lui-même ou par Pierre Sonnerat, représentant essentiellement les plantes et les animaux des Mascareignes et de Madagascar que l'on pouvait y observer en 1770. Nous nous intéressons particulièrement aux vingt-deux planches figurant des reptiles, plus précisément des tortues (10), des lézards (8) et des serpents (4), reproduites pour la première fois dans leur ensemble.

Corvoheteromeyenia Ezcurra de Drago, 1979 is exclusively known from Neotropical Region with two species recorded: C. australis (Bonetto & Ezcurra de Drago, 1966) and C. heterosclera (Ezcurra de Drago, 1974). The genus is characterized by the presence of birotuled gemmuloscleres inserted radially embedded in the gemmule, by megascleres which are exclusively oxeas, occasionally sparsely microspined and pseudobirotuled microscleres present in two distinct series. A total of twelve specimens were collected in São Francisco Basin (Bahia State, Brazil) and identified as belonging to Corvoheteromeyenia. Based on this material, we record C. heterosclera for São Francisco Basin. Additionally, we describe a new species of Corvoheteromeyenia that differs from other species of genus by having gemmulosclere sanidaster. Sanidaster display an intermediate morphology between the birotule and rodlike (acanthostrongyle) spicular type. The gemmulosclere sanidaster found here could be interpreted as malformations due to environmental conditions, since malformations in gemmuloscleres had previously been observed in experimental conditions in some freshwater sponges exposed to heavy metal. However, in these conditions only 50% of gemmoscleres were malformed, and in C. sanidastosclera n. sp., 100% of gemmoscleres were sanidasters. Thus we do not believe that this morphology of spicules was the result of exposure to chemical compounds in the environment. This result reinforces the idea of Penney & Racek (1968) that the segregation of Spongillidae Gray, 1867 into two groups based on the form of gemmoscleres as proposed by Vejdovsky (1887) is no longer justified.

The present contribution is a catalogue of the Jean Risbec collection, including specimens mounted on microscope slides and belonging to Eupelmidae Walker, 1833 or originally described in Eupelmidae, as well as the point-mounted or card mounted specimens originally on these slides. Lectotypes are designated for 19 species. Eleven new combinations are proposed. The genus Fanamokala Risbec, 1960 described in Pteromalidae Dalman, 1820 is treated as a junior synonym of Eupelmus Dalman, 1820, subgenus Episolindelia Girault, 1914 n. syn. The following seven specific or subspecific synonymies are made: Anastatus aliberti var. bruniptera Risbec, 1951, Anastatus nezarae Risbec, 1951, and Anastatus rhynchitidi Risbec, 1951 n. syn. of Anastatus (Anastatus) aliberti Risbec, 1951, Brasema leersiae var. garouae Risbec, 1955 n. syn. of Eupelmus (Episolindelia) australiensis (Girault, 1913), Brasema leersiae Risbec, 1956 n. syn. of Eupelmus (Episolindelia) testaceiventris (Motschulsky, 1863), Bruchocida batataephila Risbec, 1951 n. syn. of Eupelmus (Eupelmus) elongatus Risbec, 1851, and Macreupelmus australis Risbec, 1952 n. syn. of Eupelmus (Eupelmus) fissicollis Risbec, 1952. Specific status is proposed for Anastatus pseudocreobotrae Risbec, 1951 n. stat., Eupelmus (Macroneura) psychephagus Risbec, 1951 n. stat., Neanastatus bicolor Risbec, 1951 and Neanastatus platygasteri Risbec, 1956 n. stat., all described originally as varieties. Vignalia halyomorphae Risbec, 1951 is removed from synonymy under Anastatus nezarae Risbec, 1951 as Anastatus (Anastatus) halyomorphae (Risbec, 1951) rev. stat. and n. comb.

Ten new species of Muricidae Rafinesque, 1815 are described from material collected during expeditions in Madagascar. Five species are described from the Extreme South: Vokesimurex rectaspira n. sp., Timbellus goniodes n. sp., Flexopteron akainakares n. sp., Murexsul mananteninaensis n. sp. and Typhinellus constrictus n. sp.; four from the Northwest: Vokesimurex aliquantulus n. sp., Timbellus pannuceus n. sp., Typhinellus laminatus n. sp. and Siphonochelus (Siphonochelus) aethomorpha n. sp.; and a single species, Bouchetia wareni n. sp., is described from both the Extreme South and the Northwest and is also reported from Mayotte. Similar species from Madagascar, Mozambique and from other regions of the Indo-West Pacific are compared. The radulae of Vokesimurex rectaspira n. sp., Flexopteron akainakares n. sp., Flexopteron primanova (Houart, 1985) and Bouchetia vaubanensis Houart, 1986 are illustrated.

A new species of Iraella Nieves-Aldrey, 1994 (Cynipidae Latreille, 1802: Aylacini Ashmead, 1903) is described from South East Romania (Dobrudja province), Iraella ionescui n. sp., which induces galls in the base of stems of Papaver rhoeas L. The most important diagnostic characteristics for the adults and galls of the new species are discussed and illustrated. In addition, Aylax papaveris (Perris, 1840), Barbotinia oraniensis (Barbotin, 1964) and Aylax minor Hartig, 1840 are also reported from Romania for the frst times. The lectotypes of Barbotinia oraniensis (Barbotin, 1964) and Parnips nigripes (Barbotin, 1964) are designated. A key to all Aylacini species inducing galls on poppies is given. In addition, a list of parasitoids reared from cynipid galls on Papaver spp. is provided.
