A new beetle species Notocupes pingi sp. nov. (Coleoptera: Cupedidae) is described from the well-known fossil site of Daohugou. With more than fifty species, Notocupes is the biggest Mesozoic genus of beetles but had not been previously found at this locality.

One new fossil genus and four new fossil species are described from the Late Tithonian-Berriasian Yixian Formation (Huangbanjigou) in China: Sinosperchopsis silinae gen. et sp. nov., Hydrophilopsia shatrovskiyi sp. nov., H. hydraenoides sp. nov. and H. gracilis sp. nov. (Coleoptera: Hydrophiloidea). The genus Sinosperchopsis is compared with all Mesozoic hydrophiloid genera known so far.

Four new species of Paraneseuthia Franz are described: P. spinosa sp. nov. (Sumatra), P. bicolor sp. nov. (Sumatra), P. quadrifoveata sp. nov. (Borneo, Sabah) and P. levigata sp. nov. (Papua New Guinea). An identification key to Australo-Oriental species of Paraneseuthia is given, and detailed morphology of the genus is described and illustrated on the basis of species from the northern and southern extremes of the known distributional range. Comparative analysis of morphology of E Palearctic and Australo-Oriental lineages of Paraneseuthia revealed only minor differences, restricted to the meso-and metaventrite and the aedeagus, and discussion of their systematic value is provided.

A new genus and species of Chilocorini (Coleoptera: Coccinellidae) from New Guinea, Sicardiana aureomarginata is described and illustrated based on adults. Characters concerning similarities to other Chilocorini genera are discussed. Key to New Guinean genera of Chilocorini and a checklist to the known species of the tribe from New Guinea are provided.

Chilocorellus Miyatake is presently recorded from China. Three new species from this genus are described and illustrated in detail: C. quadrimaculatus sp. nov., C. protuberatis sp. nov., C. tenuous sp. nov. A diagnosis of the genus and a key to the known species are also given.

A new subgenus, Sulcignathos sub. nov., is erected to include Pachylister baconi, P. luctuosus and P. scaevola. The new following synonyms have been established: P. baconi (Marseul, 1854) = P. assamensis (Marseul, 1857) syn. nov., P. luctuosus (Marseul, 1854) = P. spinipes (Marseul, 1854) syn. nov., All the species of Sulcignathos are keyed and a general distribution is given for each of them. P. baconi is new to Nepal.

Orphinus (Orphinus) changdoi sp. nov. is described from Korean peninsula. The habitus, antennae, and male genitalia are illustrated and compared with a related species from the same area. Some complementary morphological details are added to the description of O. mroczkoxvskii Háva et Kadej, 2006 and the species is moved to the subgenus Falsoorphinus Pic, 1931 from nominotypical subgenus.

A new species from Vietnam, Lema victoris sp. nov., is described and illustrated.

The Greek species belonging to the genus Crypticus Latreille, 1817 (Coleoptera: Tenebrionidae: Diaperinae) are revised. Types of C. (Crypticus) thessalicus Reitter, 1896 are examined and a new species is described from the islands of Samos, Lesvos and Kos: C. (Platycrypticus) brusteli sp. nov. A key to species, photographs of habitus, geographical informations and a distribution map are bringing.

The synantropic species Gonocephalum patruele (Erichson, 1843) is studied and separed from Gonocephalum sericeum (Baudi, 1875) previously confused with the West African species, introduced in Cabo Verde Islands and Transvaal, and separated in base of male and female genitaliae, pubescence of body and other characters. Both species belongs to a group of synantropic species, including Gonocephalum rusticum (Olivier, 1811). Gonocephalum patruele is studied and Gonocephalum sericeum (Baudi, 1875) stat. rest. previously confused with this species is redescribed from Egypt and from Almería, Spain, introduced from Northern Africa. Gonocephalum sericeum, described from “Persia mer.” is a species widely distributed in Northern Africa, from Morocco to Egypt, Israel and the Arabian Peninsula. The localities of origin and the geographic dispersal of this species are discussed. A new species, from Central Mongolia previously confused with Gonocephalum patruele ssp turchestanicum Gridelli, 1948, is described: Gonocephalum soederbomi sp. nov. and separated from Gonocephalum patruele ssp. turchestanicum Gridelli, 1948 from Iran and from Turkestán. Gonocephalum puberulum Kaszab, 1952 is treated as a new homonymy of Gonocephalum puberulum Fauvel, 1867 nom. preocc. The name Gonocephalum javae nomen nov. is hereby proposed. Other taxa are described : Gonocephalum labriquei sp. nov. from China and G. dentitibia iwani ssp. nov. from North Rhodesia.

Anchophthalmus muelleri sp. nov. from Tanzania is described and illustrated. The distribution map is provided.

The catalogue of all known World species of the genus Gonocephalum Solier, 1834 is presented: 3 subgenera, 415 species and subspecies are listed. The data of primary types and distribution for known species and subspecies are included. Gonocephalum zoltani nom. nov. is proposed as replacement name for Gonocephalum parallelum Kaszab, 1952 (nec Gonocephalum setulosum var. parallelum Normand, 1936) which is junior homonym; Gonocephalum neoblairi nom. nov. is proposed as replacement name for Gonocephalum Blairi Kaszab, 1952 (nec Opatrum blairi Gebien, 1922, presently placed in Gonocephalum) which is junior homonym. The following new homonyms are presented for the species presently placed in Gonocephalum: Hopatrum arenarium Fairmaire, 1894 nom. preoccup., nec Opatrum arenarium Fabricius, 1775; Gonocephalum curvicolle Gridelli, 1934 nom. preoccup., nec Gonocephalum curvicolle Reitter, 1889; Gonocephalum pubens Gebien, 1913 nom. preoccup., nec Opatrum pubens Marseul, 1876; Opatrum pusillum Küster, 1849 nom. preoccup., nec Opatrum pusillum Fabricius, 1791; Opatrum viennense Küster, 1849 nom. preoccup., nec Gonocephalum viennense Duftschmid, 1812; Opatrum modestum Küster, 1849 name preoccup. nec Opatrum modestum Reiche, 1847; Opatrum patruele Küster, 1849 nom. preoccup. nec Opatrum patruele Erichson, 1843; Opatrum setulosum Küster, 1849 nom. preoccup., nec Opatrum setulosum Faldermann, 1837. Incertae sedis taxa are listed separately.
