Lectotypes for P. alticolus F. Morawitz, 1876, P. herzi F. Morawitz, 1891 and P. labiatus Eversmann, 1852 are designated. Panurginus niger Nylander, 1848, the type species of the genus, was studied for the first time after it was described. Panurginus dubius Osytchnjuk, 1995 is a junior synonym of P. niger Nylander, 1848. Panurginus alticolus, P. crawfordi Cockerell, 1914, P. herzi V. Morawitz,P. labiatus, P. romani Aurivillius, 1914, P. niger and P. nigripes F. Morawitz, 1880, are redescribed and seven new species are described: P. alpotanini, P. arsenievi,P. kozlovi, P. kropotkini, P. mikhno, P. muraviovi, P. obruchevi. In Russia, P. alticolus and P. labiatus are first recorded for Siberia; P. alticolus is a new record, and one species is newly described from Kazakhstan; P. niger and P. herzi are first recorded, and two species described from Mongolia. A key to the 14 species with 118 illustrations, and annotated list along with data on types, synonymies, general geographical distribution, the material examined and descriptions for all species is presented.

Fergusonina omlandi Nelson and Yeates sp. nov. is the first species of fly from the genus Fergusonina to be described from the Eucalyptus pauciflora Sieb. ex Spreng. (Snow Gum) species complex; although another two species occur in sympatry on this host at higher elevations. Fergusonina omlandi sp. nov. can be distinguished from the latter by differences in adult size and markings on the mesonotum and morphology of the dorsal shield of the larva. The other new species, Fergusonina williamensis Nelson and Yeates sp. nov. and Fergusonina thorn-hilli Nelson and Yeates sp. nov. are the first fliesto be described from Eucalyptus baxteri (Benth.) Maiden & Blakely and Eucalyptus dalrympleana Maiden, respectively. These two species can be distinguished from all other described Fergusonina by host specificity, adult colour and setation and morphologyof the dorsal shield.

    Repeatability and precision in proboscis length measurements for long proboscid flies

Most ecological studies aim to measure the functional proboscis length as a response or predictor variable. Here I suggest a proxy for this, the Maximum Functional Length (MFL), obtained by combining the lengths of the prementum and labrum. I also quantify errors in proboscis measurements due to a lack of consideration of the extensible ventral rostral membrane (VRM). Results show that naive measurements allow for substantial unrepeatable variation (mean: 7mm; maximum 14mm).

    查看更多>>摘要:Alisotrichia Flint, 1964 is an exclusively New World genus of microcaddisfiies (Hydroptilidae), currently assigned to Leucotrichiini. Until now, this genus contained 51 species, of which only 1 has been described from Brazil. In this paper, 4 new species are described from Southern Brazil, 3 in the A. orophila Group (A. holzenthali sp. nov., A. macae sp. nov., and A nessimiani sp. nov.) and one in the A. hirudopsis Group (A. ubatuba sp. nov.). The new species are separated by features of the terminalabdominal segments and structures of the male genitalia.
