The survey of shell-bearing heterobranchs of the order Cephalaspidea of the Kara Sea has been done based on unpublished and literature data. The studied material includes that collected during expeditions aboard R/V Professor Multanovskiy in August–September 2019 and R/V Dalnie Zelentsy in August 2012. Additionally, the material of collections of the Zoological Institute of the Russian Academy of Sciences (Saint Petersburg) has been studied. The fauna of heterobranch molluscs of the order Cephalaspidea in the Kara Sea includes 18 described and 1 undescribed species that belong to 10 genera and 6 families. It has been specified that the type locality of Retusa semen Reeve, 1855 (Port Refuge) is located at Port Refuge National Historic Site of Canada, Devon Island, Nunavut, not in the Kara Sea. Retusa semen is considered here as species inquirenda because of the brief original description, significant differences in drawings of the shell of this species made by different authors, and the absence of type specimens. The presence of Diaphana minuta Brown, 1827, Laona quadrata (Wood, 1839), Philine sinuata Stimpson, 1851 and Retusa semen in the Kara Sea needs confirmation. Species numbers of heterobranch molluscs of the order Cephalaspidea decrease from the Barents Sea (21) through the Kara Sea (19) to the Laptev Sea (15) because of the decreasing proportion of boreal-arctic species. Among cephalaspids of the Kara Sea, the highest average abundance (individuals/m2) was observed for Cylichnoides densistriatus (Leche, 1878), and the highest average biomass for Cylichna corticata (Møller, 1842). The proportion of live individuals in the populations does not exceed 18% in late August – early September. The taxonomic structure of the cephalaspid fauna of the Kara Sea has been studied based exclusively on morphological characters. Further study of the fauna is needed based on molecular analyses of the material fixed in 96˚ alcohol.

Different Color

In 1958 Deichmann synonymized Holothuria inornata Semper, 1868 with Holothuria kefersteinii (Selenka, 1867). This nomenclature has been adopted until now. However, some specimens recently collected from the Mexican Pacific matched the original description of H. inornata Semper (1868) whereas others matched the original description by Selenka (1867). A morphological, molecular and ecological study of the specimens was conducted to confirm the identification of these specimens. The morphological characters of our specimens were compared with those contained in the original descriptions and figures of the types of both species. Besides the different color pattern of live specimens of both species, the main differences found are the presence of straight distally perforated rods in the dorsal papillae, and the presence of Holothuriophilus trapeziformis Nauck, 1880 in the cloaca of H. inornata, versus the absence of these kind of rods in the dorsal papillae, and the absence of symbionts in the cloaca in H. kefersteinii. The species identified by Deichmann (1958) as H. kefersteinii is, in fact H. inornata. Both species might have been confused because the morphology of preserved specimens is very similar and the presence of the straight rods in papillae might have been overlooked during identification. A more thorough review of the ossicles from the specimens, together with the comparison of ossicles from the type specimens, has allowed the resurrection of long-forgotten species, H. inornata

This study is focused on the Chinese fauna of the leaf beetle genus Chlamisus Rafinesque, 1815 (Coleoptera: Chrysomelidae) and three new species are described, namely C. corollinotatus sp. nov. from Guangxi, and C. lycocephalus sp. nov. and C. varipennatus sp. nov. from Yunnan. The number of the Chinese Chlamisus is thus increased to 66. Twenty-five species are redescribed with the emphasis mainly on the genital morphological characters that are observed and reported for the first time for most species of the genus from China. Color plates and line drawings of general habitus and other detailed structures are also provided. Chinese fauna of the genus is keyed to species. Type specimens of the new species and other materials included in this study are deposited in the Institute of Zoology, the Chinese Academy of Sciences, Beijing.

Precise Locality

Since the time of the original description there have been no precise locality records in Cambodia of Bertia cambojiensis (Reeve, 1860) and it was believed to be extinct. In 2012, a joint Natural History Museum survey with Vietnamese colleagues rediscovered living populations of this huge sinistral helicoid snail in a protected area of southern Vietnam. The genitalia and radula morphology are re-assessed and type specimens of all recognised congeners are figured herein. The unique morphological characters of this species are a small and simple penis, well-developed amatorial organ complex that incorporates four amatorial organ ducts, a short gametolytic organ complex and spiked papilla, and radula morphology with unicuspid teeth. The type locality of B. cambojiensis, which has been contentious, is determined here to be in the vicinity of ‘Brelum’, Vietnam, near the border with Cambodia. In addition, the nucleotide sequences of barcoding genes COI, 16SrRNA and 28S fragments were provided for further comparison.

Rollo Howard Beck (1870–1950) was a professional bird collector who spent most of his career on expeditions to the Channel Islands off southern California, the Galápagos Islands, South America, the South Pacific, and the Caribbean. Some of the expeditions lasted as long as ten years during which time he and his wife, Ida, were often working in primitive conditions on sailing vessels or camps set up on shore. Throughout these expeditions, Beck collected specimens for the California Academy of Sciences, the Museum of Vertebrate Zoology at Berkeley (California), the American Museum of Natural History, and the Walter Rothschild Museum at Tring, England. Beck was one of the premier collectors of his time and his contributions were recognized by having 17 taxa named becki in his honor. Of these taxa, Beck collected 15 of the type specimens.

Ramalina sekika Asahina is reported for the first time from Russia from Sakhalin. It refers to the number of rare and poorly investigated species of the genus. Until now it was considered to be endemic to northeastern China. The original description and the location in the Far East are given, as well as the data on anatomical and morphological study of the Russian specimen. The differences in the anatomical structure of its thallus are discussed. A comparison of anatomical and morphological characters of R. sekika, R. pollinaria (Westr.) Ach. (European material), R. yasudae Räsänen has been made; the author considers them as independent species.

Unusual Finding

A new species of Pogonophora obtained from one station at a depth of 25 m from near the Dikson Island in the Kara Sea is described. Galathealinum karaense sp. nov. is one of the largest pogonophorans, the first known representative of the rare genus Galathealinum Kirkegaard, 1956 in the Eurasian part of the Arctic Ocean and a highly unusual finding for the desalted shallow of the Yenisey Gulf. Several characters occurring in the new species are rare or unique among the congeners: under-developed, hardly discernible frills on the tube segments, extremely thin felted fibres in the external layer of the tube, and very faintly separated papillae in the anterior part of the trunk. Morphological characters useful in distinguishing species within the genus Galathealinum are defined and summarised in a table. Diagnosis of the genus Galathealinum is emended and supplemented by new characters. Additionally, three taxonomic keys are provided to the species of Galathealinum and to the known species of the Arctic pogonophorans using either animals or their empty tubes only, with the brief zoogeographical information on each Arctic species.

Nearly a century ago, wing venation was introduced in gracillariid taxonomy as a means to diagnose closely related genera and species groups. Recent advances in non-destructive virtual micro-dissections suggest promising approaches with which to revisit the relevance of wing venation characters on historic primary type specimens. Many unique type specimens in Gracillariidae and other microlepidoptera groups preserved in museum collections are in poor condition, and over the course of history have suffered loss or damage to their abdomens. Consequently, genitalia morphology is not available for diagnoses and comparisons. In this paper we emphasize the need to include the type species and type specimens into the broader context of taxonomic studies on micro-moths in general and the family Gracillariidae in particular. The genus Caloptilia has a world-wide distribution and has been the subject of research for more than 200 years, yet the generic boundaries and groupings within the genus are still unresolved due to the lack of a reliable set of taxonomic characters obtained from the primary types. We describe a method of virtual descaling of the fore- and hindwings using the unset micro-moth type specimen of Caloptilia stigmatella Fabricius, 1781, in order to demonstrate that the study of historic and fragile type specimens and diagnoses of their internal morphological characters becomes possible by applying new and non-destructive technology.

Within Astraea Klotzsch (1841: 194), Astraea lobata (Linnaeus 1753: 1005) Klotzsch (1841: 194) may be considered the most taxonomically complex species due to its wide geographical distribution and the several varieties that have been proposed for this species by Müller Argoviensis (1866, 1874). In his concept, Müller Argoviensis (1866) united under Croton lobatus Linnaeus (1753: 1005) plants with 3–5-partite leaves almost as long as the petioles, subulate stipules, the bracts not well developed and ovaries with varied indumentum. In De Candolles’s Prodromus, Müller Argoviensis (1866) recognized eight varieties, maintaining this concept in the Flora Brasiliensis (Müller Argoviensis 1874) with few modifications. Morphological characters and geographical distribution support the recognition of some of these varieties as species distinct from A. lobata. As part of an undergoing taxonomic revision of Astraea, these distinct taxa must be validly published for further studies on this genus. Therefore, in this note we propose these novelties with commentaries about morphology and geographic distribution, along with photos to illustrate them and lectotypifications when necessary.
