The generic diagnosis of the monotypic Glanitaenia is amended based on a detailed morphological examination of newly collected specimens of G. osculata (Goeze, 1782) (syn. Proteocephalus osculatus) found in wels catfish, Silurus glanis Linnaeus, 1758, from Neuchâtel, Switzerland. Several morphological characteristics of G. osculata are described for the first time or better specified, such as uterine development (type 2 according to the classification by de Chambrier et al., 2004, 2015), the presence and peculiar position of a vaginal sphincter (previously not reported), its egg morphology, description of scolex microtriches and a dense network of osmoregulatory canals in the posterior part of the scolex and the anterior region of the neck (proliferative zone). The anterior position of the vagina, which opens anterior to the cirrus-sac, not ventral as typical for most of the closely related species of the Proteocephalus aggregate, may represent apomorphy of this taxon. Glanitaenia osculata is reported from Italy (River Po basin), Romania (River Danube delta) and Switzerland (Aare/Rhine River basin) for the first time. This expansion of the parasite distribution area may be related to a recent introduction of wels catfish to West Europe.

The Afrotropical genus AurotalisBłeszyński, 1970 is briefly reviewed and two new species are described and illustrated: A. cristatasp. n. and A. dicksonisp. n.Charltona argyrastis Hampson, 1919 is transferred to AurotalisBłeszyński, 1970. A list of the known species and a diagnosis of each species are given. Illustrations of new diagnostic morphological characters are presented.

Definite or probable type specimens of 60 species of Orthoptera described by Ignacio Bolívar have been identified in the collections of the Muséum d'histoire naturelle de Genève. The species are listed alphabetically by suborder and family, and the valid combination is given. Information about the label data and condition of primary type specimens is provided.

We record two megophryid species for the first time from Vietnam: Leptobrachium masatakasatoi and Leptolalax minimus. Acoustic analysis of L. masatakasatoi is also reported based on advertisement calls of the male specimen from Son La Province. In addition, data of morphology and natural history of afore mentioned species are provided.

Pheidole leloi is described as a new species based on a colony series collected in an evergreen forest on the Da Lat Plateau's eastern edge (Hon Ba Nature Reserve, Khanh Hoa Province, Vietnam). It is the first discovery of the Pheidole quadricuspis group in the Indo-Chinese Peninsula. The p-distance between COI sequences of P. leloi and its putative named allies of the species group is 13.4-15.8%. This may indicate that P. leloi has been genetically isolated for several million years. An ancestor of P. leloi probably expanded its distribution into the Indo-Chinese peninsula during the Miocene expansions of rainforests, and survived into rainforest patches (refugia) during the Quaternary glacial age.

The type status is described for 101 taxa classified within the superfamily Orthalicoidea and present in the Mollusca collection of the Muséum d'histoire naturelle in Geneva. A lectotype is designated for Helix (Cochlogena) citrinovitrea S. Moricand, 1836. Bulimus fidaensis J. Moricand, 1858 is now considered a junior subjective synonym of Bulimus clouei Pfeiffer, 1857. New combinations are: Kuschelenia (Bocourtia) angrandi (Morelet, 1860), Leiostracus fidaensis (J. Moricand, 1858), Protoglyptus heterogrammus (S. Moricand, 1836), Protoglyptus longisetus (S. Moricand, 1846), Drymaeus (Mesembrinus) polygrammus (S. Moricand, 1836), Kara viriata (Morelet, 1863).

The insect species Psyllipsocus stupendus spec. nov., living on rock outcrops, is described and illustrated from central Mexico (Morelos state). Although the general morphology is typical for a Psyllipsocus species, both male and female are characterized by very peculiar genitalia. In the male, the phallosome has a pair of long pointed claspers and, surprisingly, the basal struts are not anteriorly but posteriorly directed. In the female, the first and second ovipositor valvulae, usually much reduced in this genus, are well developed and strongly sclerotized, forming a tube-like structure together with the sclerotized wall of the proximal part of the vagina. The dorsal wall of the female genital chamber is transversally double-folded, resulting in a ventral main compartment and an eversible dorsal compartment. The opening of the spermathecal duct (spermapore) opens proximally into the dorsal compartment. A similar structure of the female genital chamber has never been observed in Psocoptera before. Some functional hypotheses are discussed and it is postulated that a special form of selective pressure, probably due to sexual selection, might have favoured the evolution of these unique genital structures.

Stéfano Moricand (1779-1854) and his son Jacques (1823-1877) were amateur scientists active in Geneva. Moricand senior was interested in botany, mineralogy, entomology, and malacology. Between 1820-1847 he published 11 papers on botany, in which he described 110 taxa (including three genera). From 1834-1851 six papers appeared from his hand in which he introduced 72 malacological taxa. Moricand junior published only four malacological papers within a relatively short time (1853-1860), with 16 new species. Biographies and a bibliography, together with a list of their newly introduced taxa, are given for both. The history of their malacological collection and their contacts with other contemporary malacologists are presented, including brief data on J. S. Blanchet (1807-1875) and A. Brot (1821-1896) who were closely linked to this collection, which covered both terrestrial and freshwater molluscs. The type material present in the Muséum d'histoire naturelle in Geneva, of the molluscan, non-Orthalicoid taxa of S. and J. Moricand is figured, complementary to Breure, 2016 (Mollusca, Orthalicoidea).

A new species of cockroach, Gurneya rothi sp. nov., is described from Brazil. Rhabdoblatta erubescens (Gerstaecker, 1883) and Rh. punctipennis (Saussure, 1895) are transferred to the genus AfricalolampraRoth, 1995. A lectotype of Audreia carinulata (Saussure, 1895) is designated. The Neotropical genus AudreiaShelford, 1910 is ascribed to the tribe Morphnini McKittrick, 1964. A detailed morphological description of the new species is given, and Africalolampra erubescens, A. punctipennis, Audreia carinulata and Pinaconota bifasciata (Saussure, 1862) are redescribed. The male genitalia of G. rothi sp. nov., Africalolampra erubescens, A. punctipennis and the structures of ovipositor of Africalolampra erubescens and Audreia carinulata are described for the first time.

Colilodion schulzi sp. n. from Palawan, the Philippines, is described based on a female specimen. The new species possesses three-segmented antennae with conspicuously broadened apical antennomeres. Habitus images of the new and all previously described Colilodion species are provided. A revised key to the Colilodion species is included.

Scaphidium solukhumbu sp. nov. and S. yeti sp. nov. are described from Eastern Nepal. Scaphidium sp. possibly representing an undescribed species is reported from Chitwan National Park, Nepal. Published records of Scaphidium quadrimaculatum Olivier from India are considered to be based on misidentifications.

This study reports on several specimens of two large hydroids from the North-Western Pacific Ocean: Monocoryne bracteata and Candelabrum phrygium. Both species are documented with photographs of the living animals as well as with photographs of the nematocysts and histological sections of the sporosacs. Both are rare animals and only known from a few specimens, which makes it difficult to assess their intraspecific variation. The new material differs in some minor details from previously known material and the significance of this is discussed here. It is concluded that these differences likely represent intraspecific variation. A re-examination of type material of Candelabrum verrucosumBonnevie, 1898 added to knowledge of this nominal species and provided evidence that it is conspecific with C. phrygium. The diagnostic feature “nematocyst buttons on the sporosacs” of C. verrucosum occurs also in otherwise typical C. phrygium identified by other authors.

The crab spider genus CebrenninusSimon, 1887 is redefined based on morphology of adult males and females. Cebrenninus now is constituted of 10 nominal species. The following new species are described: Cebrenninus banten sp. nov., C. berau sp. nov., C. magnus sp. nov., C. phaedrae sp. nov., C. schawalleri sp. nov., and C. tangi sp. nov. Three new synonyms are proposed: Libania scabriculaThorell, 1890 syn. nov., Libania scabricula sulcataThorell, 1890 syn. nov., and Libania annulataThorell, 1890 syn. nov. = Cebrenninus rugosusSimon, 1887. Cupa kalawitanaBarrion & Litsinger, 1995 is removed from the synonymy of C. rugosus and placed as a distinct species in Cebrenninus, i.e. C. kalawitana (Barrion & Litsinger, 1995) comb. nov. Morphological comparison of Cebrenninus and AscurisomaStrand, 1929 shows that the latter should be considered a junior synonym of the former. Thus, Ascurisoma striatipes (Simon, 1897) is transferred to Cebrenninus, C. striatipes (Simon, 1897) comb. nov. Crockeria kinabalu gen. et sp. nov. from Mt Kinabalu National Park, Sabah, is described on the basis of its exceptional palp which has a median apophysis in addition to conductor and embolus. Libania laevisThorell, 1890 syn. nov. is transferred to this new genus, now being called Crockeria laevis (Thorell, 1890) comb. nov.

A new species of OtiorhynchusGermar, 1822 of the subgenus ChoilisanusReitter, 1912 is described from the Aegean Island Lesbos (Greece). The new species is morphologically close to O. (Choilisanus) magnicollisStierlin, 1888 from Ikaria and Samos Island, and to O. formanekiReitter, 1913 from Asia Minor.
