Three New Species

The Neotropical water scavenger beetle genus Chasmogenus Sharp, 1882 is a diverse lineage with 34 described species. Here, three new species from the southwestern margin of the Guiana Shield are described using an integrative approach combining adult morphology and molecular data: Chasmogenus clinatus sp. n. (Brazil: Amazonas, Venezuela: Amazonas), C. gironae sp. n. (Venezuela: Amazonas), and C. inpa sp. n. (Brazil: Amazonas). Examination of the male genitalia is essential for confident identifications and thus unassociated females may prove extremely difficult to identify. New distributional records in Brazil for C. acuminatus Smith & Short, 2020 are provided as well as habitus images of newly described species and an updated key to the species from Venezuela, Suriname, Guyana, French Guiana and northern Brazil.

Three New Species

The Venezuelan species of the genus Gyrinus Geoffroy, 1762 are reviewed (Gyrinidae: Gyrininae: Gyrinini). The Venezuelan Gyrinus fauna is found to be comprised of nine species distributed among the subgenera Neogyrinus Hatch, 1926 and Oreogyrinus Ochs, 1935, although Gyrinus (Oreogyrinus) colombicus Régimbart, 1883 is known from imprecisely localized and potentially mislabeled specimens and the species presumably does not occur in Venezuela. Three new species are described: G. (Oreogyrinus) vinolentus sp. nov. from the Andes, and G. (Oreogyrinus) iridinus sp. nov. and G. (Neogyrinus) sabanensis sp. nov., from the Guiana Shield region. Two new synonymies are established: G. amazonicus Ochs, 1958 syn. nov. is synonymized with G. guianus Ochs, 1935, and G. racenisi Ochs, 1953 syn. nov. is synonymized with G. ovatus Aubé, 1838. Gyrinus (Oreogyrinus) feminalis Mouchamps, 1957, described from Venezuela from two female syntypes only, is considered as species inquirendum, as the types were not found. For each species a dorsal habitus, illustration of male and female genitalia, and distribution map are provided. A key and checklist for the Venezuelan Gyrinus species is included.

Three New Species

Abstract The fauna of bristletails of the genus Lepismachilis Verhoeff, 1910 in Montenegro and Serbia includes only one species L. (Berlesilis) targionii (Grassi, 1887) with 2 + 2 eversible vesicles on abdominal urocoxites II–VI. Three new species of this genus are described: L. (Lepismachilis) prijepolja sp. nov., L. (Lepismachilis) limensa sp. nov. from Serbia, and L. (Lepismachilis) alexandrae sp. nov. from Montenegro. All described new species belong to the species group of the subgenus Lepismachilis s. str. with 2 + 2 eversible vesicles on abdominal urocoxites II–V. Lepismachilis prijepolja sp. nov. differs from L. y-signata Kratochvíl, 1945 and L. notata Stach, 1919 by the color, drawings and ratios of the compound eyes; ratios of sensory field on fore femur of male, number of divisions of ovipositor. Lepismachilis limensa sp. nov. differs from L. hauseri Bitsch, 1974 and L. abchasica Kaplin, 2017 by ratios of paired ocelli, sensory field on fore femur of male; ratios and chaetotaxy of maxillary and labial palps. Lepismachilis alexandrae sp. nov. differs from L. abchasica by the drawings of the compound eyes; ratios of paired ocelli, sensory field on fore femur of male; number of divisions of the parameres and gonapophyses. A list of the Machilidae occurring in Balkan Peninsula is also provided.

North And South

Some 2,000 Ptiliidae collected in the North and South Islands of New Zealand in 1983/1984 by Peter Hammond of the Natural History Museum, London, are determined to 34 species, four of which are new to the country. As there are very few previous records, most from the Auckland district of North Island, the Hammond collection provides much new distributional data. The three new species: Nellosana insperatus sp. n., Notoptenidium flavum sp. n., and Notoptenidium johnsoni sp. n., are described and figured; the genus Ptiliodes is moved from Acrotrichinae to Ptiliinae, and Ptenidium formicetorum Kraatz recorded as a new introduction. Information is provided to aid separation of the new species from those previously recorded.
