A new species of the genus Megophrys is described from Guizhou Province, China. Molecular phylogenetic analyses based on mitochondrial DNA indicated the new species as a clade clustered into the Megophrys clade. The new species can be distinguished from its congeners by a combination of the following characters body size moderate (SVL 40.0-45.5 mm in males and 48.9-51.2 mm in females); vomerine teeth absent; tongue not notched behind; tympanum distinctly visible, oval; a small horn-like tubercle at the edge of each upper eyelid; two metacarpal tubercles in hand; toes with rudimentary webbing; heels overlapping when thighs are positioned at right angles to the body; tibiotarsal articulation reaching the level of mid-eye when leg stretched forward; in breeding males, an internal single subgular vocal sac present and brownish nuptial pads, made up of black nuptial spines, present on the dorsal base of the first two fingers.The biodiversity of mollusks, particularly cephalopods, has not been exhaustively determined in the Revillagigedos ecoregion, which is a biodiversity hotspot for several marine groups located in the Tropical East Pacific Province. In our study, we detected and examined ocellate octopuses from Socorro and Clarion Islands, and determined their identity using morphological criteria and molecular data from two mitochondrial genes (COIII and COI). The taxon identified was Octopus oculifer, a species considered endemic to the Galapagos Archipelago. In addition, according to our analyses, O. mimus, O. hubbsorum and O. oculifer are very closely related and may represent a species complex comprised of three morphotypes. We found that the evolutionary relationships among octopuses are not determined by the presence of ocelli. This study is the first to report a clade represented by ocellate and non-ocellate species, in addition, the identity of cephalopods in the Revillagigedos was determined with analytical support.Linnaeus described five species presently included in the genus Timarcha Chrysomela goettingensis, Tenebrio caeruleus, Tenebrio laevigatus, Tenebrio latipes, and Tenebrio rugosus. After a study of the relevant material, the identity of these species has been established. The following synonyms are proposed or confirmed Timarcha goettingensis (Linnaeus, 1758) = T. latipes (Linnaeus, 1767), syn. nov.; Timarcha caerulea (Linnaeus, 1758), comb. nov. = T. balearica Gory, 1833, syn. nov. = T. balearica Pérez Arcas, 1865, syn. nov.; Timarcha rugosa (Linnaeus, 1767) = T. scabra (Olivier, 1807), syn. conf. = T. generosa Erichson, 1841, syn. conf.; Timarcha laevigata (Linnaeus, 1767) = T. tenebricosa (Fabricius, 1775), syn. conf.. The type of Tenebrio caeruleus is a Chrysomelidae currently belonging to genus Timarcha and therefore can no longer be considered a Tenebrionidae (Helops caeruleus) nor the type species of genus Helops. For the sake of nomenclatural stability, an application to the International Commission on Zoological Nomenclature to change the relative precedence of Timarcha caerulea and retain usage of T. balearica will be made. An application to change the relative precedence of Timarcha laevigata has been submitted, which would lead to the conservation of usage of T. tenebricosa as valid. Lectotypes are designated for Chrysomela goettingensis, Tenebrio latipes, Tenebrio caeruleus, Timarcha balearica Gory, T. balearica Pérez Arcas, Tenebrio rugosus, Chrysomela scabra, Timarcha generosa, Tenebrio laevigatus, and Chrysomela tenebricosa. For each of the valid species the diagnosis, distribution, and host-plant data are reported.The Caucasus and adjacent areas are inhabited by fifteen species of mayflies of the genus Epeorus, subgenus Caucasiron Kluge, 1997 (Heptageniidae). This identification guide aims to facilitate an accurate species identification of their larvae and sum up all available information on their taxonomy and distribution. An identification key is provided, and the important diagnostic characters of all species are described and illustrated. The larva of E. (C.) insularis (Braasch, 1983) is described for the first time. This study enables the routine identification of Caucasiron larvae necessary for biomonitoring and hydrobiological research in the Caucasus region.A herpetofaunal inventory was conducted on Bidong Island, Terengganu, Peninsular Malaysia. It incorporates data from a recent herpetological survey conducted from 1 to 3 April 2019 with reptile records from previous publications. Specimens were collected with drift-fenced pitfall traps and taxa were recorded with visual encounter surveys (VES). In total, 18 species of reptiles and amphibians were recorded, including three species of frogs, 12 species of lizards, and three species of snakes. Six species from the present survey are new records for the island.In this paper, four species of the genus Diduga Moore, [1887] from China (Chongqing and Guangdong) and Malaysia (Borneo, Sabah) are described as new to science, namely D. simianshanasp. nov., D. chebalingasp. nov., D. chewisp. nov., and D. hollowayisp. nov. Adults of these species are illustrated in color, and images of the male and female genitalia are provided. A distribution map of the new species is provided, together with an updated checklist of all species of Diduga.The endemic Neotropical genus Gaujonia Dognin is revised. Morphological characters and a phylogenetic analysis demonstrate paraphyletic relationships among the species. Four different groups are interpreted to represent four different genera. The G. arbosi group is the only remaining clade in the genus Gaujonia, and the other groups have been arranged into three new genera Milleranagen. nov., Oculicattusgen. nov., and Cicadoformagen. nov. Additionally, two other genera Cicadomorphusgen. nov., and Gaujopteragen. nov. were found using morphological and molecular analyses based on some specimens that were misidentified as Gaujonia spp. A total of five new genera, three new combinations (Cicadoforma vau-nigrum Hampson, comb. nov., Oculicattus renifera Hampson, comb. nov., and Millerana arbosioides Dognin, comb. nov.) and 21 new species (Cicadoforma ocelotussp. nov., Cicadomorphus chicharrasp. nov., Cicadomorphus chuyasp. nov., Cicadomorphus falkasiskasp. nov., Cicadomorphus lilianaesp. nov., Gaujonia bichusp. nov., Gaujonia chiqyaqsp. nov., Gaujonia kanakusikasp. nov., Gaujonia sourakovisp. nov., Gaujoptera amsasp. nov., Millerana austinisp. nov., Millerana cajassp. nov., Millerana cundinamarquensissp. nov., Millerana matthewsaesp. nov., Millerana tigrinasp. nov., Oculicattus bolivianasp. nov., Oculicattus brehmisp. nov., Oculicattus incasp. nov., Oculicattus raizaesp. nov., Oculicattus schmidtisp. nov., and Oculicattus uturunkusp. nov.) are established.Celaenorrhinus pyrrha de Nicéville, 1889, a rare species of Hesperiidae previously known to be distributed from northeastern India to Indochina, is reported from southwestern Yunnan and southwestern Chongqing, China. A 658 bp COI gene sequence of this species is published for the first time. Although Chongqing is obviously isolated from the main distribution range, morphological characters of the specimens from this locality do not indicate a subspecies differentiation. Another rare taxon, C. read more munda munda (Moore, 1884), is also recorded from China for the first time based upon a male specimen from Cuona County in the Tibet Autonomous Region. This is the second specimen of C. munda from China, over 100 years after the holotype of C. munda joka Evans, 1949. The genitalia of both species are illustrated and described. Some taxonomic notes and a distribution map are provided as well.A new species of the parasitic wasp Coptera Say was previously distinguished from other species via correspondence between ecological (host) differences and DNA barcodes. A description and figures for Coptera tonicsp. nov., along with revisions to existing keys that allow it to be distinguished from other Nearctic species without the aid of molecular characters, is provided in this work.The distinction between the two closely related genera Oligoneuriella Ulmer, 1924 and Oligoneuriopsis Crass, 1947 has been much debated. First described from South Africa, Oligoneuriopsis seemed to be a clearly defined genus. However, as the known distribution of the genus widened and knowledge on it expanded, species delimitation based on morphology became less clear due to overlap in several apparently defining morphological characters, especially in the nymphs. This work attempts to reassess Oligoneuriopsis morphology in the context of all currently known species. The type species, Oligoneuriopsis lawrencei Crass, 1947 is redescribed at the imaginal and nymphal stages and a neotype is designated. The putative nymph of Oligoneuriopsis dobbsi (Eaton, 1912) is described based on material collected around Mt Elgon (Kenya). The adults of Oligoneuriella orontensis Koch, 1980 are described for the first time and the species is transferred to the genus Oligoneuriopsis (Oligoneuriopsis orontensiscomb. nov.). Egg structure is also described for the first time for the species Oligoneuriopsis skhounate and O. orontensis. Some biogeographical considerations are also given. It is likely that more species will still be discovered, especially in Africa."Land and freshwater molluscs of Gran Canaria (Spain)" is an occurrence dataset containing 389 observations of 59 different taxa of land and freshwater molluscs encountered on Gran Canaria, an island central in the Canarian archipelago (Spain). Of these 59 different (sub)species, 27 are with certainty currently endemic to the island of Gran Canaria. Various sites were inspected in a period between 1988 and 2020. The dataset is published as a standardized Darwin Core Archive and includes for each observation a stable occurrence ID, scientific name, date, and location of the observation, as well as information on life stage and organism quantity. It also contains supplementary remarks on the determination and the observation itself and links to associated media. We have released this dataset to the public domain under a CC0 1.0 Universal (CC0 1.0) Public Domain Dedication. The aim is to contribute to the knowledge on the ecology and distribution of these species on the island, such that it may aid conservation and research of these organisms in the future. Issues with the dataset can be reported at https//github.com/BelgianBiodiversityPlatform/landsnails-occurrences.On the African continent, the genus Garra consists of several species often insufficiently separated from each other by diagnostic characters. Herein, a detailed morphological redescription of Garra makiensis from the Awash River drainage is presented, together with additional data on the type specimens of G. makiensis and G. rothschildi. Mitochondrial CO1 sequence data are also provided, including the historic paralectotype of G. makiensis, with a comparison to Garra species from Africa and the Middle East. Based on these sequences, G. makiensis clusters outside the group of African congeners and is a sister lineage to species from the south-east of the Arabian Peninsula. Although morphologically variable, G. makiensis is characterised by having a single unbranched pectoral-fin ray, a short distance between vent and anal-fin origin (7.3-19.7 % of pelvic - anal distance), chest and belly covered with scales, and a prominent axillary scale at base of pelvic fin (18.8-35.5 % of pelvic-fin length).
