Hypogean Molopina of Pyrenees with the description of a new species of Zariquieya Jeannel, 1924 from Spain (Coleoptera, Carabidae, Pterostichini).

A second blind species of the genus Zariquieya Jeannel, 1924, Z. boumortensis n. sp., is described from the southern slope of central Spanish Pyrenees (Lleida, Spain). Morphological structure of the new species, especially male and female genitalia as well as the external morphology suggests that this carabid beetle should be included in the genus Zariquieya, created for a single species endemic of eastern Spanish Pyrenees. The new species is morphologically distinct from Z. troglodytes Jeannel, 1924 by numerous characters like maxillary palpus glabrous, pronotum more transverse, frontal impressions lighter, and elytra with flat disk without strong lateral and apical declivity. A key for identification of Pyrenean Molopina is given, and ecology and biogeographical considerations are detailed, including distribution map of Pyrenean hypogean Molopina.

A new genus and species of eomeropid, Jurathauma simplex n. gen., n. sp., is described from the Middle Jurassic of Inner Mongolia, China. It can be distinguished from all known eomeropid genera by a combination of these characters: two rows of cells formed by crossveins between costal margin and ScP; RP MA with five branches; MP with five branches; and three anal veins. The presence of this new species and Tsuchingothauma shihi Ren & Shih, 2005 of the same family in this locality suggests the early diversification of eomeropids with cockroach-like body during the Middle Jurassic.

The specimens of the French freshwater mussels (Mollusca, Bivalvia, Unionoidea) in the Arnould Locard collection in the Muséum national d'Histoire naturelle in Paris were examined. 216 type series for 308 nominal species were located, including taxa described by Locard and by other workers of the “Nouvelle École”. An annotated list of all 308 species is provided, including data regarding the relevant primary literature, type status and localities, and subsequent taxonomic opinions.

Calastacus kurentae n. sp. is the second species of Calastacus from France and Europe besides C. laevis de Saint Laurent, 1972. The description is based on two small specimens collected on the continental slope of the Bay of Biscay, off Brittany (France). The holotype is nearly complete while the second specimen is much damaged with a missing carapace; it is not considered a paratype. Calastacus kurentae n. sp. differs from all known Calastacus species by having a pair of large distal spines on the rostrum and spinules on lateral borders of the telson. It can be distinguished from C. laevis by the pereopod 1 bearing a small subdistal spine on both the upper and lower borders of the merus along with a fine longitudinal upper carina on the propodus; by contrast in C. laevis, there are one large upper spine and five large lower spines on the pereopod 1 merus and no upper carina on the propodus. Also in the new species, the terminal suture on the uropodal exopod is faint and unarmed while it is well defined and bears spinules in C. laevis.

The grasshopper fauna from Huascarán National Park and the valleys of “Callejón de Conchucos” and “Callejón de Huaylas”, Perú, has been sampled during two surveys of the area in 2004 and 2008. In this paper, two new genera (Tiyantiyana n. gen. and Huaylasacris n. gen.) and six new species collected during the surveys are described: Tiyantiyana sunipenis n. gen, n. sp., Huaylasacris maxicerci n. gen, n. sp., Maeacris chilikuti n. sp., M. saytu n. sp., M. ayasqa n. sp. of the subfamily Melanoplinae and Orphulella chumpi n. sp. of the subfamily Gomphocerinae. Previous records on the highland grasshoppers of the Peruvian Andes were almost nonexistent. The new acridids described here were collected at the high-altitude puna grassland, between 3182 and 4660 m a.s.l. Puna is one of the most heavily modified natural regions of Peru. Since grasshoppers are a useful group for bioindication, it is important to acquire knowledge on their diversity in such environmental conditions.

A new genus and a new species of Seirini (Entomobryidae) are described. The new genus, Tyrannoseira n. gen., is represented by three Brazilian Seira-like species with a peculiar type of sexual dimorphism: the first pair of legs of adult males bears several spine-like setae in distinct positions, the femur is enlarged and the tibiotarsus is slender. The combination of these morphological features produces clasping structures used during male-male interactions. The new genus is known only from Caatinga, a unique semi-arid biome exclusively present in Brazil. A new species, Tyrannoseira sex n. sp., is also described from São João do Cariri, Paraíba State. Seira raptora and S. bicolorcornuta, described from Caatinga, are also included in the newly described genus. An identification key for the three species of the new genus is also given. Sexual dimorphism and aspects of the systematics of Seira are discussed.

Four new species of Muricidae are described from the Philippines and the Caribbean area. The first two (Homalocantha granpoderi n. sp. and H. ninae n. sp.), from the Philippines, are compared with four closely related species: H. scorpio (Linnaeus, 1758), H. pisori d'Attilio & Kosuge, 1989, H. vicdani d'Attilio & Kosuge, 1989 and H. dondani d'Attilio & Kosuge, 1989. The need for comparisons based on an ontogenetic growth series is underlined for these species. For the first time, the growth series of each discussed species is illustrated. Siratus pointieri n. sp., from the Dominican Republic, is compared with three closely related species: S. cailleti (Petit de la Saussaye, 1856), S. motacilla (Gmelin, 1791) and S. kugleri (Clench & Pérez Farfante, 1945). Murexsul (M.) jahami n. sp., from Martinique, is compared with M. (M.) sunderlandi (Petuch, 1987), M. (M.) oxytatus (Smith, 1938), M. (M.) zylmanae (Petuch, 1993) and M. (M.) chesleri Houart, 2006. The characters of the spiral sculpture are described using precise structural homologies for each species.

Epiaeschna matutina (Zhang, 1989) is re-described and species diagnosis is amended. Two new species, Aeshna shanwangensis n. sp. and Aeshna forficatum n. sp., are described from the Middle Miocene deposit of Shanwang Formation, Shandong Province, East China. Comparison with other related fossil and recent species is provided.
