Surveys of the Insects of the Danum Valley Conservation Area in Sabah, Malaysia yielded species of the Scaphidiinae genus Cyparium Erichson, 1845. In the present paper, four are described while a fifth potential new species, only represented by a single female, is left undescribed. A key to the ten species of Cyparium known at present to occur in the Sundaland is provided.

The genus Lederina Nikitsky & Belov, 1982 (Melandryidae: Melandryinae) is recorded for the first time from Taiwan with six new species: L. armadillo sp. nov., L. formosa sp. nov., L. insula sp. nov., L. smetanai sp. nov., L. viti sp. nov., and L. yushanensis sp. nov., which are described and illustrated. A key to the Taiwanese species is given. The lack of knowledge concerning the species of Lederina as well as the possible diversity of the genus in eastern Asia is briefly discussed.

The present report provides new records, taxonomic notes, descriptions and redescriptions of several species of lesser-known thecate hydroids. Five species belong to the family Sertularellidae Maronna et al., 2016, one to the Syntheciidae Marktanner-Turneretscher, 1890, and one to the Aglaopheniidae Marktanner-Turneretscher, 1890. Type material of Sertularella conica Allman, 1877 was re-examined, and a modern redescription is provided, together with notes on its problematic synonymy that now includes S. gayi unituba Calder, 1991. Fertile specimens of S. inconstans Billard, 1919 are rediscovered, and its synonymy is broadened through the inclusion of S. natalensis Millard, 1968. A new species, S. malagasiensis sp. nov., is described from the south of Madagascar. Sertularia exigua/laxa Allman, 1888, a hydroid assignable to the genus Sertularella Gray, 1848, is found to have both primary and secondary homonyms; its taxonomy is discussed, and the replacement name S. mutatnomen nom. nov. is introduced for it. Sertularella pellucida Jäderholm, 1907 is recorded for the first time from the Mid-Atlantic Ridge, outside its previously-known main area of occurrence, in the Arctic Ocean. The sexually-dimorphic gonothecae of Synthecium brucei Vervoort & Watson, 2003 are described for the first time. Halicornaria setosa Armstrong, 1879 is rediscovered in material from the Red Sea, and the binomen is removed from the synonymy of Taxella eximia Allman, 1874, while transferring it to the genus Taxella Allman, 1874, as T. setosa comb. nov., on the account of its gonothecae not protected by phylactocarps.

The current knowledge on Epichilo Ragonot, 1889 is briefly discussed. The two Oriental species, E. parvellus Ragonot in Joannis & Ragonot, 1889 and E. vartianae Błeszyński, 1965 are compared with each other and illustrated, and the female of E. vartianae is described based on seven specimens collected in mangrove habitats in the Bushehr Province, south Iran. The genus Epichilo and E. vartianae are newly reported for the fauna of Iran.

Nine new Psyllipsocus species are described and illustrated. Three species from the Greater Sunda Islands: P. hollieri sp. nov. (Indonesia: Sumatra), P. uncinatus sp. nov. (Malaysia: Borneo: Sabah), P. bauensis sp. nov. (Malaysia: Borneo: Sarawak), and six species from Thailand: P. fusciceps sp. nov., P. prominens sp. nov., P. simplex sp. nov., P. cluniopilosus sp. nov., P. bidentatus sp. nov., P. quadridentatus sp. nov. They belong to four small groups of species which are each characterized by at least one striking autapomorphy (e.g. a novel possibly proprioreceptive male abdominal organ). One of these species groups includes also P. disparunguis Lienhard, only known from the United Arab Emirates. The number of Psyllipsocus species known from the Oriental Region is herewith augmented to 26, 17 of them recorded from Southeast Asia.

Henri de Saussure described 54 species and one subspecies currently placed in the family Blattidae, five of them in collaboration with Leo Zehntner. These species are listed alphabetically with an account of the type specimens found in the Muséum d'histoire naturelle de Genève. The location of type specimens in other museums is given where known. The current binominal combination for each species is provided. Photographs of six type specimens found in the Muséum d'histoire naturelle de Genève are presented with the labels associated with each.

Anauchen whitteni sp. nov. is described and illustrated based on specimens collected in Guangxi Zhuang Autonomous Region, southwestern China. The new species is diagnosed by havinh four apertural barriers and a rounded body whorl.

The Carcinological Collection of the División Zoología Invertebrados, Museo de La Plata (FCNyM UNLP) currently contains 2446 lots, of which 124 represent type material. There is a total of 162 batches corresponding to parasitic crustaceans. Six orders are represented in the collection and recorded here: Arguloida, Cyclopoida, Siphonostomatoida, Harpacticoida, Isopoda, and the infraclass Rizocephala, belonging to four classes of the Suphylum Crustacea. The species names are listed in systematical order, and the type locality, collection number, current taxonomic status and original bibliographic reference are given. Host and site of infection are also provided.

A key challenge of natural history museums across the globe is to make collections accessible to researchers and the public alike. Through advances in digitization, databasing, online data curation and long-term storage, it is now possible to give access to the type material housed in museums, which represent the most precious specimens in collections. Here, we have generated a fully illustrated online catalogue of all primary and secondary Diptera types housed in the Muséum d'histoire naturelle of Geneva (MHNG). High-resolution habitus photographs of all type specimens and their labels are available on a digital repository, and an exhaustive list of this type material is provided. The MHNG collection holds 152 holotypes and 2025 paratypes with Empididae, Lauxaniidae, Sphaeroceridae and Tephritidae being the most represented families. Although the current Diptera collection is relatively recent, the ca. 150 000 specimens and associated type material are important resources for future taxonomic and systematic studies.

We report on verified cases of longevity in the Japanese Fire-bellied Newt Cynops pyrrhogaster. Two individuals obtained as adults in 1978 died in July 2008 and November 2017, resulting in an individual minimum lifespan of 33 and 42 years, respectively, possibly even longer. Another four individuals of C. pyrrhogaster were received in 1975 and living now for more than 47 years, with two individuals received as adults likely having reached a lifespan of 50 years already. Another adult male C. pyrrhogaster was obtained in 1991 and died in 2022 at an accordingly estimated age of >34 years. Previously reported lifespans for C. pyrrhogaster in human care were 20-25 years, with only a single report of 40 years. However, other species of Cynops and Hypselotriton are also apparently long-lived, such as H. cyanurus chuxiongensis (25 years), H. orientalis (32 years), and C. ensicauda (43 years). With these documented cases, the lifespan of Fire-bellied Newts is exceeded only by few other species of Caudata, such as Andrias japonicus (70 years), Cryptobranchus alleganiensis, Salamandra salamandra (>50 years), and Proteus anguis (100 years). Our report thus indicates that decades-long lifespans in salamandrid newts, viz. substantial longevity, might be rather common and could be considered a rule, not an exception.
