A new name, Aleuroclava tarennae, is proposed for Aleuroclava davidi Dubey and Sundararaj, 2005, a homonym of Aleuroclava davidi Qureshi, 1982. Aleurolobus exceptionalis Regu and David, found infesting Madhuca latifolia (Sapotaceae) in India, is redescribed and its intraspecific variation reported. An African whitefly, Aleurolobus gruveli Cohic is recorded for the first time in India. A new species, Dialeurodes atalantiae, infesting Atalantia racemosa (Rutaceae) in India, is described and illustrated.

Syrista xiaoi Wei, sp. nov. (Cephidae: Hymenoptera) is described from Sichuan, China. Syrista xiaoi is similar to S. similis Mocsàry, 1904. Syrista Konow 1896 is redescribed in detail. A key to species of the genus is provided and new distribution records are given.

A new monotypic genus of Naupactini (Coleoptera: Curculionidae), Thoraconaupactus del Rio and Lanteri is described based on the new species Thoraconaupactus vaninii del Río and Lanteri (Type locality: Brazil, Bahia, Itaji). Two different morphotypes are distinguished by characters of the vestiture: one from Itaji, with integument brown, smooth, and vestiture mostly setose; the other from Ibiraba with integument black, rugose and vestiture mostly squamose. Thoraconaupactus is similar to Naupactus Dejean and Teratopactus Heller in several characters, and shows some unique features such as the strongly transverse pronotum with a sub-basal tooth-like projection on each side. Specimens were collected in association with a species of Leucaena (Fabaceae). The paper includes habitus photographs and line drawings of genitalia, mouthparts, and other external features of taxonomic value.

A new record of phoretic copulation is reported for a pair of specimens of Dissomphalus xanthopus Ashmead, taken joined using Malaise trap in Lexington, Kentucky U.S.A.

The spermathecae of four species of the asilid genus Dysmachus (D. cephalenus, D. obtusus, D. safranboluticus, and D. tricuspis) were studied with both light and scanning electron microscopy (SEM). There are three spermathecae the species examined. The spermatheca consists of receptaculum seminis (reservoir), ductus receptaculum (spermathecal ducts), ejection apparatus, apodemes of furca and furca. Receptaculum seminis of D. cephalenus, D. obtusus, D. safranboluticus and D. tricuspis have a swollen structure at the base but it extends apically like a duct. Sperm is kept in receptaculum seminis. In all species, the spermathecal ducts are covered by chitin layer. Spermathecal ducts are not connected with a common duct, but open separately to the bursa copulatrix. The ejection apparatus controls the passage of spermatozoa. The ejection apparatus are covered by strong muscles that regulate its opening and closing. Furca in D. cephalenus and D. tricuspis divided, with a triangular apodeme, lateral arms broad; Y-shaped in D. obtusus and D. safranboluticus.

A new species of Pleurocerinella, P. neotropica, from Bolivia is described. It is closest to P. dioctriaeformis known from Indomalaysia and Africa.

Distributional and systematic notes on northeastern Algerian Helophoridae species are given. Two newly recorded species [Helophorus (sensu stricto) aquaticus (Linnaeus, 1758) and Helophorus (R.) lapponicus Thomson, 1853] are described, and their distribution in Algeria and worldwide is presented. The total aedeagophore length of H. aquaticus may reach 1.0–1.1 mm.

A new species of Otiorhynchus is described from western Turkey. Otiorhynchus (Pliadonus) lilligi sp. n., is easily distinguishable from O. (Pliadonus) frater Styerlyn, 1861 by the existence of a sharp tooth on the mesofemora of the former.

Two new tephritid species, Cornutrypeta hunanica sp. nov. and Cornutrypeta gansunica sp. nov. from China are described and illustrated. A revised key to all the Cornutrypeta species is provided.

The species of the genus Trichonta Winnertz (Diptera: Mycetophilidae) from China are revised. Six species are recognized, including two species new to science: T. aberransida sp. nov. and T. rostriforma sp. nov. A key to species of the genus is provided.

Pachyotoma emeiensisis sp. nov. characters is described from Sichuan Province, P. R. China. It differs from the 15 known species of the genus Pachyotoma in presence of both secondary granulation and endoskeletal reticulation on the body and 3 distinct teeth on mucro. Remarks on the taxonomical status of genera Pachyotoma and Bonetrura are provided.
