A replacement name for the preoccupied subgenus Somatidia (Microsoma) Breuning, 1951 (Coleoptera, Cerambycidae)

The replacement name Somatidia (Nanosoma) nom. nov. is introduced for the Cerambycidae subgenus Somatidia (Microsoma) Breuning, 1951 (Coleoptera, Cerambycidae, Lamiinae, Parmenini), which is preoccupied by the genus name Microsoma Macquart, 1855 (Diptera, Tachinidae).

Découverte d’une nouvelle population de Rhithrogena delphinensis Sowa & Degrange, 1987, dans le massif des Arves, et compléments à la description de la larve (Ephemeroptera, Heptageniidae)

Discovery of a new population of Rhithrogena delphinensis Sowa & Degrange, 1987, in the Arves Massif, and additions to the morphological description of the larva (Ephemeroptera, Heptageniidae). Rhithrogena delphinensis, described originally on the basis of four larvae from the Western Alps, south of the Arves Massif and from the northern flank of the Ecrins Massif, had not been captured again since 1986. Here, we report the discovery of a new population from river Arvan, whose drainage basin is located between the Grandes Rousses Massif and the northern flank of the Arves Massif. This newly discovered population seems abundant in numbers, and reveals the particular ecological requirements of the species as well as its dependence on glacier fed or nival streams. The morphological characteristics of the larvae are described in detail, and illustrated by photographs. The variability of some of the proposed identification criteria is discussed, and a key to the identification of the Rhithrogena species from the alpestris group of the Western Alps, to which R. delphinensis belongs, is provided. Finally, a portion of 658 base pairs of the COI gene of R. delphinensis is sequenced for the first time and compared to already existing data on the alpestris group in the Western Alps.

Description de deux nouvelles espèces de Collaria Provancher de Madagascar (Hemiptera, Miridae, Mirinae, Stenodemini)

Description of two new species of Collaria Provancher from Madagascar (Hemiptera, Miridae, Mirinae, Stenodemini). Collaria elsae n. sp. and C. sabinae n. sp. are described from Madagascar. Habitus and genitalia are illustrated in both sexes for C. sabinae n. sp., and only for the female, only sex known, for C. elsae n. sp. These two species, black in color, are separated from African species with a black habitus, by a set of external characters and by the genitalia. Collaria bourbonica Matocq, 2019, described and known only from Reunion, is reported from Madagascar and Grande Comores. A key to the Afro-tropical species of Collaria is given.

Les Eutheiini de la faune de France. II. Le genre Eutheia Stephens, 1830 (Coleoptera, Staphylinidae, Scydmaeninae)

Eutheiini of the French fauna. II. The genus Eutheia Stephens, 1830 (Coleoptera, Staphylinidae, Scydmaeninae). A synthesis of the data about morphology, taxonomy, ecology, biology and chorology of the French species belonging to the genus Eutheia Stephens, 1830 (Eutheiini) is presented. Lectotypes are designated for E. clavata Reitter, 1882 and E. minutissima Sainte-Claire Deville, 1901. Two new synonymies are proposed: E. scydmaenoides orientalis Franz, 1971, n. syn. for E. scydmaenoides Stephens, 1830, and E. scydmaenoides tyrolensis Franz, 1971, n. syn. for E. scydmaenoides Stephens, 1830. Eutheia formicetorum Reitter, 1882, is new for Algeria, Bulgaria, Morocco and Tunisia; E. plicata (Gyllenhal, 1813) is new for Slovenia; E. parallela Fairmaire, 1879, is new for Greece (Rhodes).

The Limoniidae collected during the All-Taxa Biodiversity Inventory in Mercantour National Park, France (Diptera)

During work for the All-Taxa Biodiversity Inventory (ATBI) in Mercantour Park, in French Alps, 23 Limoniidae species were collected. Among them, three are new to French fauna: Dicranomyia (Dicranomyia) imbecilla Lackschewitz, 1941, Dicranomyia (Glochina) transsilvanica Lackschewitz, 1928, and Molophilus (Molophilus) priapus Lackschewitz, 1935. Altitudinal data and other results are commented on.

New taxonomic and ecological data for Paraprisopus apterus, the smallest stick insect from French Guiana (Phasmatodea, Pseudophasmatidae, Paraprisopodini)

The egg and the adult female of Paraprisopus apterus Conle, Hennemann, Bellanger, Lelong, Jourdan & Valero, 2020, from French Guiana, are described here for the first time. Ant-mimicking morphology and behaviour of post-hatch Paraprisopus nymphs are reported and discussed.

Première mention pour la Martinique et l’Amérique d’un sclérogibbide africain, Caenosclerogibba probethyloides Olmi, 2005 (Hymenoptera, Sclerogibbidae)

First record for Martinique and America of the African sclerogibbid Caenosclerogibba probethyloides Olmi, 2005 (Hymenoptera, Sclerogibbidae). Caenosclerogibba probethyloides Olmi, 2005, a species known from Africa south of Sahara, is recorded for the first time from the America. It has been collected in Martinique.

The Clytini fauna of Benin and Togo, with the description of a new species from Benin (Coleoptera, Cerambycidae)

Four species are reported for the first time in Benin, Carinoclytus cf. semiruber (Quedenfeldt, 1882), Chlorophorus deterrens (Pascoe, 1862), Denticerus muehlei Mourglia & Téocchi, 1994, and Plagionotulus sylvaticus Hintz, 1911; a new species is described, Calanthemis jossomonforti n. sp. In Togo, four species are known and Denticerus muehlei Mourglia & Téocchi, 1994, is reported for the first time. Plagionotulus sylvaticus Hintz, 1911, is cited from Ivory Coast for the first time. An identification key to species of Clytini from Benin and Togo is provided.

Description of a new species of Nomada Scopoli, 1770, from France (Corsica) (Hymenoptera, Apidae). Nomada legoffi n. sp., a new species of bee of the genus Nomada Scopoli, 1770 (Hymenoptera, Apidae) from southern Corsica is described and illustrated.
