An investigation of the blackfly fauna of Andalusia,southern Spain (Diptera: Simuliidae)

A detailed account is provided of the blackfly (Simuliidae) fauna of Andalusia, southern Spain. The work is based on a study of 14204 specimens, of which 13733 were collected by the authors from a total of 137 positive sampling sites during prospections made mainly in early summer 1986 and in the spring seasons of 1994—1998. In all, 25 identified species and two possible species of uncertain identity are recorded. The topographical and climatic background is briefy described, data from previous literature and material from earlier collections are covered, a checklist of the blackflies of Spain and Portugal is provided, and the character of the simuliid fauna is discussed for areas within and outside Andalusia.     

甘肃鸡类分类区系研究

本文记述甘肃鸡类19种,另9个亚种,占国内鸡类57种的33.33％,国家保护的珍稀种类11种,占种数的57.89％。古北界种类占优势,占63.16％,其中以高地型种类为主。区系组成与青海、四川二省更接近。山地阻隔,差异悬殊的生态环境促进了分布区广,进化趋势强烈的种的亚种分化。     

Notes on astogeny of some Petraliellidae (Bryozoa) from Australia

Members of the bryozoan family Petraliellidae share the capacity to develop basal rhizoids, which anchor the unilaminar, semi-repent parts of the colonies above the substratum, and enable them to overgrow other, competing sessile forms. Little is known of the larval behaviour and settlement, or the early astogeny of species. Ancestrulate colonies of the Australian Tertiary lunulitiform species Smittia biincisa are referred to the genus Riscodopa, and together with Riscodopa paucipora sp. nov. are described and compared with the Recent species R. cotyla and R. parva from New Zealand, and with R. hyalina sp. nov. from New South Wales, Australia. All the Recent species are known to develop basal rhizoids, and an early astogeny similar to that of many other small, rooted bryozoans, comprising the post-metamorphosis development of a binary complex, including rhizoid and feeding elements, is inferred for Riscodopa. Observations on living Hippopetraliella magna from Queensland suggest that both the ancestrular morphology and early astogeny show a capacity for semi-repent growth, even though they do not include rhizoid development. Larvae metamorphose without direct attachment, and the ancestrula develops elongated, partially calcified supporting processes, which raise the early stages of growth above the substratum. A similar kind of ancestrula has been found in preserved specimens of Mucropetraliella ellerii.

贵州兴义中三叠世黔鱼龙属(爬行纲: 鱼龙目)一新种

A new species of Qianichthyosaurus Li, 1999 from the Zhuganpo Member of the Falang Formation (Ladinian, Middle Triassic), Wusha Town, Xingyi City of Guizhou is described here, namely Qianichthyosaurus xingyiensis sp. nov. The recognition of the new species revises the diagnosis of the genus: tooth size relative to the skull width slightly below 0.1; ulna peripheral “shaft” notched or largely reduced; hindlimb nearly equal or longer than forelimb; tibia peripheral “shaft” notched or largely reduced. Qianichthyosaurus xingyiensis sp. nov. differs from the type species in having relatively longer snout (snout length/skull length over 60%); humerus radial facet being prominently larger than ulnar facet; unenclosed obturator foramen on pubis; fibula posterior process on the posterior margin and the ischium sub-triangular lacking shaft. The new species is stratigraphically older than Q. zhoui, the specimens of which were exclusively known from the Wayao Member of the Falang Formation (Carnian, Late Triassic). Along with askeptosaurid thalattosaur Anshunsaurus and shastasaurid ichthyosaur Guizhouich- thyosaurus, the occurrence of Q. xingyiensis sp. nov. in Xingyi Fauna suggests a closer relationship between Xingyi Fauna (late Ladinian, Middle Triassic) and Guanling Biota (Carnian, Late Triassic).     

The Old World genera of Meloidae (Coleoptera): a key and synopsis

This paper reviews the 77 Old World genera of blister beetles (Coleoptera: Meloidae). Included is a key to genera and a synopsis of each genus. The generic synopses incorporate synonyms, number of species, geographic distribution, and the most significant references on taxonomy, life history and certain other topics. Additional notes are appended to several of the generic treatments. Formal nomenclatural changes include two new generic synonymies, one new status, three new combinations and the transfer of one subgenus.
