Neben biogeographischen werden morphologische Argumente zusammengetragen, die für eine Synonymisierung der Arten Acalles parvulus Boheman, 1837 = Acalles temperei Péricart, 1987 sprechen. Entlang eines Transekts zwischen dem Mont Pilat (Dep. Loire) und dem Mont Saint-Martin nördlich von Grenoble (Dep. Isère) wird über den Vergleich der Aedoeagi eine Cline sichtbar, die am Artstatus von Acalles temperei zweifeln lässt. Bestätigung finden diese vergleichenden, phänotypischen Untersuchungen durch erste molekulargenetische Untersuchungen. Danach scheint entweder eine Hybridisierungszone wahrscheinlich oder der Verdacht liegt nahe, dass Acalles parvulus und Acalles temperei eine einzige, geographisch strukturierte Art darstellen. Völlig anders liegen die molekularbiologischen Ergebnisse bei Kyklioacalles roboris (Curtis, 1834) und der erst kürzlich resynonymisierten Art Kyklioacalles navieresi (Boheman, 1837): Die DNA-Sequenzanalysen der mitochondrialen CO1- und 16S-Gene sowie des nukleären 28S-Gens zeigen, dass Kyklioacalles navieresi und Kyklioacalles roboris zwei eigenständige, wenn auch eng verwandte Arten darstellen.
To better understand the dung beetle (Coleoptera: Scarabaeidae: Scarabaeinae) biodiversity of Costa Rica and Panama, new synonyms, records, distributions, and updates are presented. This paper analyzes the distribution and taxonomy of Phanaeus olsoufieffi Balthasar, 1939 in Panama and establishes the following new subjective synonym: Phanaeus panamensis Moctezuma and Halffter, 2021 = Phanaeus olsoufieffi Balthasar, 1939. Color morphs of Phanaeus pyrois Bates, 1887 in Costa Rica are analyzed. The Costa Rican distribution of Onthophagus bidentatus Drapiez, 1819 and O. marginicollis Harold, 1880 is studied. Onthophagus bidentatus is recorded for Costa Rica for the first time. A population analysis of barcode mtDNA, color morphs, and morphological and genitalia characters for different body sizes of Onthophagus cyanellus is undertaken. An mtDNA barcode tree is presented to assess the molecular identity of O. cyanellus resulting in the reaffirmed subjective synonymy, Onthophagus mesoamericanus Zunino and Halffter, 1988 = O. cyanellus Bates, 1887.

A remarkable morphologically and genetically distinct species of the genus Ero C.L. Koch, 1836 is described based on both sexes from the cloud forest of the island of Saint Helena: Ero lizae sp. nov. Another new species, Ero natashae sp. nov., is also described on the basis of morphological differences in the male and female genitalia. Both species were initially reported a single species, Ero aphana (Walckenaer, 1802), from the island by Unzicker (1977).
Several millions frogs captured in the wild in Indonesia are sold for food yearly in French supermarkets, as deep frozen frog legs. They are commercialized as Rana macrodon, but up to 15 lookalike species might also be concerned by this trade. From December 2012 to May 2013, we bought 209 specimens of deep frozen frog legs, and identified them through a barcoding approach based on the 16S gene. Our results show that 206 out of the 209 specimens belong to Fejervarya cancrivora, two to Limnonectes macrodon and one to F. moodiei. Thus only 0.96 % of the frogs were correctly identified. Unless misclassification was intentional, it seems that Indonesian frog leg exporters are not able to discriminate between the species. The quasi absence of L. macrodon in our samples might be an indication of its rarity, confirming that its natural populations are declining rapidly, in agreement with its “vulnerable” status according to the IUCN Red List. Our results show that the genetic and morphological diversity of the frogs in trade is much higher than the genetic and morphological diversity measured so far by scientific studies. These results underline the need for large scale studies to assess the status of wild populations.
A new symbiotic species of liljeborgiid amphipods, Liljeborgia associata sp. nov., is described from the burrows of the spoon worm Urechis unicinctus (Drasche, 1880) (Annelida: Polychaeta: Echiura: Urechidae) in the southern part of Peter the Great Bay and Posjeta Bay in the Sea of Japan. The new species is mostly similar and probably related to Liljeborgia geminata Barnard, 1969, known from the Californian coasts of the USA, and Liljeborgia serratoides Tzvetkova, 1967, described from Posjeta Bay in the Sea of Japan, but can be clearly distinguished from all congeners by morphological features of mouthparts, appendages and telson. The new species is only the fourth in the family Liljeborgiidae to be described from the Russian coast of the northwestern Pacific and the first in association with spoon worms (Echiura).
Lebbeus sokhobio sp. nov. is described from abyssal depths (3303−3366 m) in the Kuril Basin of the Sea of Okhotsk. The related congeners are deep-water dwellers with a very distant distribution and very similar morphology. The new species is separated by minor morphological features, such as the armature of the rostrum and telson, meral spinulation of ambulatory pereiopods and the shape of the pleonal pleurae. This species is the deepest dwelling representative of the genus Lebbeus and the family Thoridae. A list of records of caridean shrimps recorded from abyssal depths below 3000 m is given.
Neoxorides Clément, 1938 is a small genus of ichneumonid wasps that develop on wood-boring beetles. We here revise the Western Palaearctic species of the genus, with a special focus on Sweden. A new species, N. striatus Johansson sp. nov. is described. Neoxorides opacus (Kokujev, 1903) stat. rev. is excluded from the synonymy with N. nitens (Gravenhorst, 1829) and reinstated as a valid species. The species is redescribed from European material. Neoxorides kissi (Ulbricht, 1911) is confirmed as a junior synonym of N. opacus. A neotype for N. opacus is designated. New characters to distinguish N. varipes (Holmgren, 1860), N. collaris (Gravenhorst, 1829) and N. montanus Oehlke, 1966 are presented. Almost all of the species treated are supported by DNA-barcoding. An illustrated key to the species occurring in the Western Palaearctic is provided, a prerequisite for making the genus accessible for future ecological and conservation studies.
The Swedish species of Enicospilus are reviewed. Three species are described from Swedish material; Enicospilus cederbergi sp. nov., Enicospilus intermedius sp. nov. and Enicospilus ryrholmi sp. nov. Four species: Enicospilus cerebrator Aubert, 1966, Enicospilus combustus (Gravenhorst, 1829), Enicospilus merdarius (Gravenhorst, 1829) and Enicospilus myricae Broad & Shaw, 2016, are reported from Sweden for the first time. An illustrated key to the Swedish species of Enicospilus is provided. Validity of the new species is supported by DNA barcoding.
In this review (third part), several species within the Nassarius pauperus complex from the eastern Indian Ocean and western Pacific are treated, including a revised concept of Nassa paupera Gould, 1850, type species of the genus Reticunassa Iredale, 1936. In the most recent taxonomic revision, several species had been synonymized with Nassarius pauperus (Gould, 1850), despite distinctive differences among these species in shell morphology. We sequenced a fragment of the mitochondrial COI and the nuclear 28S genes of all available Nassarius pauperus complex species. Automatic barcode gap discovery and reciprocal monophyly were applied to propose species delimitation hypotheses and to support a new concept of the genus. Using morphological and molecular characters, Reticunassa is elevated to full genus rank. Six new species are described: Reticunassa visayaensis sp. nov., R. poppeorum sp. nov., R. annabolteae sp. nov., R. goliath sp. nov., R. intrudens sp. nov. and R. thailandensis sp. nov., while R. tringa (Souverbie, 1864) is recognized as a valid species.
The Afrotropical species of the sphecid genus Sphex are revised. Forty-six taxa are recognized, of which fifteen are newly described: Sphex abbotti nivarius subsp. nov., S. comorensis sp. nov., S. hades sp. nov., S. nefrens sp. nov., S. occidentalis sp. nov., S. pseudopraedator sp. nov., S. pseudosatanas sp. nov., S. pulawskii sp. nov., S. rufoclypeatus sp. nov., S. satanas memnon subsp. nov., S. schmideggeri sp. nov., S. schoutedeni malawicus subsp. nov., S. socotrensis sp. nov., S. stadelmanni rufus subsp. nov. and S. victoria sp. nov. A new subgenus, Menkeella subgen. nov., is proposed for S. paulinierii Guérin Méneville, 1843.
Four former synonyms are resurrected: Sphex pruinosus var. haemorrhoidalis Magretti, 1898, for which the replacement name of S. feijeni nom. nov. is proposed, S. camerunicus Strand, 1916, S. cinerascens Dahlbom, 1843 and S. abbotti W. Fox, 1891.
Nine of the previously valid names are shown to be junior synonyms: Sphex haemorrhoidalis basuto (Arnold, 1947) and S. haemorrhoidalis kobrowi (Arnold, 1928) = S. umtalicus Strand, 1916; S. incomptus anonymus Leclercq, 1955 = S. nigrohirtus Kohl, 1895; S. neavei (Arnold, 1928) = S. abbotti W. Fox, 1891; S. observabilis (R. Turner, 1918) = S. ahasverus Kohl, 1890; S. rufiscutis (R. Turner, 1918) and S. mochii Giordani Soika, 1942 = S. jansei Cameron, 1910; S. rufiscutis laevigatus Arnold, 1951 = S. gaullei Berland, 1927; and S. stadelmanni integer (Arnold, 1928) = S. stadelmanni Kohl, 1895. Three previously synonymized species are transferred as new synonyms to different species: Sphex conradti Berland, 1927 = S. camerunicus Strand, 1916; S. kilimandjaroensis Cameron, 1908 = S. abbotti W. Fox, 1891; and S. nigripes var. pachyderma Strand, 1916 = S. umtalicus Strand, 1916. For three species, the actual type localities are on different continents than their labels indicate: Sphex ahasverus Kohl, 1890, S. castaneipes Dahlbom, 1843 and S. optimus F. Smith, 1856, with the first occuring in Africa instead of Australia and the other two presumably occuring in South America instead of Africa.
The occurrence of the argentatus group in Sub-Saharan Africa is confirmed, and seven additional species groups are established, with all but one of them based on apomorphic morphological traits. A hypothesis on the phylogenetic relationships among the subgenera and species groups of Sphex is presented, and an identification key for both sexes as well as a placoid-based identification table for males are presented. Using Bayesian inference and maximum likelihood analysis on mitochondrial and nuclear sequence data generated from thirty-one of the recognized taxa, the monophyly of the proposed species groups is corroborated.
