A new species of the genus Laboulbenia (Laboulbeniales) on Ophionea indica (Coleoptera, Carabidae, Odacanthini) from Taiwan

Laboulbenia ophioneae is described as a new species with illustrations. It is closely related to Laboulbenia celestialis and Laboulbenia asiatica because of some similarities in the morphology of appendages and perithecia. The present species from the latter two species can be distinguished by the shorter, inflated perithecia, the shorter receptacles, and the appendages consisting of more or less darkly colored, broader branches. This new species was found on elytra of Ophionea indica from Taiwan, which has been also known as a host of Laboulbenia polymorpha. A mature thallus noticed by Terada (2004) on the slide 673b (M. Ishikawa collection) and a young thallus illustrated by Sugiyama (1978, fig. 1-G as L. polymorpha) on 673d (M. Ishikawa collection) are both identified as L. ophioneae.     

Larinus berti sp. n. (Coleoptera,Curculionidae, Lixinae) from North Africa

Diagnostic characters of the new species are large size, elongate-ovate body, bisulcate sub-quadrangular rostrum, triangularly raised dorsum of rostrum, flat subgena and submentum, Y-shaped apodeme of sternite VIII of female and thin nodulus of spermatheca.     

Description of a new species and redescription of two species of the genus Limoniscus Reitter (Coleoptera,Elateridae, Dendrometrinae) from Japan

We presented a revised taxonomy of two allied species, Limoniscus mitokiiKishii, 2004 and L. ogatai (Kishii, 1985), from western Japan. Through this revision, we found a new species, L. spelunca sp. n., from the type series of L. ogatai. The new species is different in its frons, antennae, prosternum, and aedeagus compared with L. mitokii and L. ogatai. We also reviewed the current understanding of Japanese Limoniscus species, and provided a key to the 23 Limoniscus species found in Japan. urn:lsid:zoobank.org:pub:56104650-EAA9-42E9-AFC3-91D7DCA53938.     

Revision of the Indo‐African Pachycerus Schoenherr, 1823, with a description of four new species (Coleoptera: Curculionidae: Lixinae)

The Indo‐African species of the genus Pachycerus (Curculionidae: Lixinae: Cleonini) are revised. The identification of Cleonus senegalensis Gyllenhal, 1834 is discussed, its holotype rediscovered and the synonymy between C. senegalensis and Ammocleonus hieroglyphicus (Olivier, 1807) is confirmed. A neotype is established for Pachycerus opimus (Gyllenhal, 1834). Lectotypes for Pachycerus vestitus (Fåhraeus, 1834), Pachycerus badeni (Faust, 1888), and Pachycerus sellatus Faust, 1904 are designated. Pachycerus sahelicus sp. nov. (type locality: Senegal, Bambey), Pachycerus hippali sp. nov. (type locality: Saudi Arabia: Jeddah, Taif), Pachycerus barclayi sp. nov. (type locality: southern India: Manapparai), and Pachycerus simonae sp. nov. (type locality: Morocco, Western Sahara, Cap Boujdour) are described. Some remarks on taxonomy and biogeography of the species are added.

COI DNA barcoding for molecular identification of the genus Aphidius (Braconidae: Aphidiinae) in South Korea,with diagnoses of two newly recorded species

The genus Aphidius is one of the most commercially important species in greenhouse for controlling pests, especially aphids. Although 13 Aphidius species had been recorded in South Korea, it was not carefully surveyed yet. In this study, we surveyed and collected 8 Aphidius spp. including two unrecorded species. Using the DNA barcode region of mitochondrial cytochrome c oxidase subunit I (COI), sequences were newly generated for 16 molecular operational taxonomic units (MOTUs) of 8 species, except for 15 duplicates, in addition of 58 MOTUs of 18 species referred from GenBank for comparison and identification, which were reconstructed in a barcode phylogeny with Neighbor-Joining method. Then, to define each species, both Automatic Barcode Gap Discovery (ABGD) and Bayesian Poisson Tree Processes (bPTP) analyses were performed. As results, although most of Aphidius spp. could be identified by clustering into a clade, we recognized that three Aphdius species were placed in a clade, of which each species was not separated as an independent species. Our data suggested that those species demonstrating a species complex were able to be hypothesized as one species. In addition, diagnoses and illustrations of the two newly recorded species in South Korea were provided.     

Taxonomy of the genus Laena from Yunnan in China,with description of eight new species (Coleoptera: Tenebrionidae: Lagriinae)

Illustrations and a key to the known Laena species from Yunnan Province are provided.www.zoobank.org/urn:urn:lsid:zoobank.org:pub:FDEDA1E8-2F2E-4732-8DB4-FE2D7BDC75D8.     

Revision of the species of the Tychus rufus group (Coleoptera: Staphylinidae: Pselaphinae)

The species belonging to Tychus rufus group are revised. Eleven species are recognized, described and illustrated and a key to their identification is provided. Nine taxa are new to science: Tychus carpathius n. sp. from Karpathos island (Greece); T. torticornis n. sp. from Lesbos Island (Greece); T. pisidicus n. sp. and T. inermis n. sp. from southwestern Turkey; T. antiocheus n. sp. and T. effeminatus n. sp. from southeastern Turkey; T. artvinensis n. sp. from northeastern Turkey, and T. sidonicus n. sp. and T. libanus n. sp. from Lebanon.     

The most ancient bark beetle known: a new tribe,genus and species from Lebanese amber (Coleoptera,Curculionidae, Scolytinae)

Abstract Cylindrobrotus pectinatus gen. et sp.n. , a new scolytine species from Cretaceous Lebanese amber, is described. A new tribe, Cylindrobrotini trib.n. , is proposed for this unique species, which demonstrates an unusual combination of some archaic and many advanced characters. This finding suggests that the Scolytinae became a distinct lineage of Curculionoidea from the Lower Cretaceous. Fossil records are reviewed, and some remarks on the origin and taxonomic position of bark and ambrosia beetles are made. Some comments on the various phylogenetic interpretations of the last 30 years are given, particularly in respect of their correspondence with the fossil record. The early appearance of Scolytinae in the fossil record before other Curculionidae (which appeared in the Upper Cretaceous) can be used as evidence against the hypothesis of bark beetles as offspring of weevils. The question of the taxonomic rank of bark beetles (separate subfamily or family) and their placement among other groups of the superfamily remains unsolved.     

The genus Cryptophagus Herbst, 1792 (Coleoptera: Cryptophagidae) in Japan with description of a new species

The 17 species of the genus Cryptophagus Herbst known from Japan are analysed and revised. The opinions of different authors about the value of the characteristics of the external anatomy are contrasted, and an identification key and figures of the studied species are presented. Cryptophagus jaloszynskii sp. nov is described. Following a detailed study of the type material in different entomological collections, the status of taxa is revised and 3 new synonyms are proposed: Cryptophagus deceptor Grouvelle, 1919 and Cryptophagus longipennis Grouvelle, 1919 are syn. nov. for Cryptophagus dilutus Reitter, 1874 and Cryptophagus longiventris Grouvelle, 1919 syn. nov. for Cryptophagus latangulus Reitter, 1889. Cryptophagus elegans Grouvelle, 1919 resurrected from synonymy with Cryptophagus decoratus Reitter, 1874. A neotype is designated for Cryptophagus elegans Grouvelle, 1918; a lectotype and paralectotype is designated for 7 taxa: Cryptophagus decoratus Reitter, 1874; Cryptophagus deceptor Grouvelle, 1919; Cryptophagus grouvellei Bruce, 1938; Cryptophagus latangulus Reitter, 1889; Cryptophagus lewisi Reitter, 1874; Cryptophagus longior Grouvelle, 1919 and Cryptophagus longiventris Grouvelle, 1919. Cryptophagus zonatus Lyubarsky, 1995 previously known only from China is reported here for the first time from Japan. A key to all the species occurring in Japan is presented.www.zoobank.org/urn:lsid:zoobank.org:pub:7FF52749-590D-46F6-9794-1E2301906ECB
