Two new species of the superfamily Oripodoidea, Maculobates bruneiensis sp. nov. and Perscheloribates interlamellaris sp. nov., are described from Brunei. The first new species differs from other species of Maculobates by the presence of an anterior notogastral margin and a specific furrow on ventral side. The second new species differs from other species of Perscheloribates by the microfoveolate body surface. The genera Maculobates and Perscheloribates are for the first time recorded in Brunei; Maculobates is for the first time recorded in the Oriental region.

The pupae of Alepia montana Bravo, Alepia truncata Bravo, Lago et Castro and Psychoda simillima Tonnoir, belonging to the subfamily Psychodinae, are described and illustrated. The pupae of A. montana and A. truncata were collected in tree holes in the city of San Ramón de la Nueva Orán, Province of Salta and the pupa of P. simillima in small pool on the nameless stream near El Hoyo city, Province of Chubut, Argentina. The pupa of P. simillima is similar to other pupae of the genus Psychoda Latreille, being distinguished by some features in the last segment and by respiratory trumpet. These are the first pupae described of any species of the genus Alepia Enderlein.

A new species, Nannotanyderus kubekovensis, belonging to Tanyderidae (Diptera, Nematocera) from the Middle Jurassic of Siberia (Russia) is described and figured. Three hitherto known species of the genus Nannotanyderus Ansorge, 1994 are compared.

Amphisternus pubescens sp. nov. from China is described and illustrated. A key to the species of Amphisternus known in China is provided.

The subgenus Scymnus of Scymnus Kugelann, 1794 from China is revised. Fifty-six species of the subgenus Scymnus known to occur in China, including twenty seven new species are documented: Scymnus (Scymnus) impolitus sp. nov., S. (S.) obesus sp. nov., S. (S.) zhangmuensis sp. nov., S. (S.) byssinus sp. nov., S. (S.) makuensis sp. nov., S. (S.) extumidus sp. nov., S. (S.) comosus sp. nov., S. (S.) choui sp. nov., S. (S.) trachypus sp. nov., S. (S.) deltatus sp. nov., S. (S.) leigongicus sp. nov., S. (S.) arciformis sp. nov., S. (S.) luxiensis sp. nov., S. (S.) acerbus sp. nov., S. (S.) pingqianensis sp. nov., S. (S.) deflexus sp. nov., S. (S.) plautus sp. nov., S. (S.) xiongfeii sp. nov., S. (S.) recavus sp. nov., S. (S.) nabangicus sp. nov., S. (S.) fasciculatus sp. nov., S. (S.) fusinus sp. nov., S. (S.) guniujiangicus sp. nov., S. (S.) caiyanghensis sp. nov., S. (S.) serratus sp. nov., S. (S.) biconvexus sp. nov., and S. (S.) clavellatus sp. nov. Scymnus (Scymnus) sufflavus Canepari, 1997 and S. (S.) trisulicus Canepari, 1997 are recorded from China for the first time. Nomenclatural history, diagnoses, illustrations and distribution are provided for fifty-five recognized species. A key to the species from China is presented.

A new genus, Cretodascillus gen. nov. in the family Dascillidae with a new species C. sinensis sp. nov., is described from the Early Cretaceous Yixian Formation of Inner Mongolia, China. The fossil taxa described in Dascillidae have been critically reviewed and the Upper Triassic Apheloodes Dunstan, 1923 (type species A. obliquum Dunstan, 1923) and Leioodes Dunstan, 1923 (type species L. planum Dunstan, 1923) are removed from Dascillidae to Coleoptera incertae sedis, the Miocene Protoacnaeus Wickham, 1914 (type species P. tenuicornis Wickham, 1914) is transferred to Psephenidae and Miocyphon Wickham, 1914 (type species M. punctulatus Wickham, 1914) to Scirtidae.

Data on an infestation of ectoparasites on a Canarian Houbara Bustard Chlamydotis undulata, fuerteventurae Rothschild et Hartert, 1894 are presented for the first time. Two insect groups were discovered: Icosta (Rhyponotum) pilosa (Macquart, 1843) (Hippoboscidae, Diptera) and a possibly unnamed species of Philopteridae (Phthiraptera) closely allied to Otidoecus houbarae (Barthélemy, 1836). For the latter, a DNA-barcode is presented. The philopterid was found in a phoretic relationship with the hippoboscid.
