Six species of Microporella with personate ovicells are analysed from material sampled in the Indian Ocean, Red Sea and southeast Mediterranean. Consideration of highly diagnostic tiny morphological characters displayed by the primary orifice and the avicularium has made it possible to distinguish three new species, M. browni n. sp., M. maldiviensis n. sp. and M. collaroides n. sp., and to better characterise the other species. Among the latter, two species named by Audouin (1826) from Savigny's drawings (1817), M. coronata and M. genisii, are redescribed and neotypes are selected. Additionally, a new species of the M. coronata species group, Microporella hastingsae n. sp., is proposed following examination of a museum specimen recorded as M. ciliata var. coronata (Hastings 1927). The species dealt with in thisstudy revealed remarkably different patterns of geographic distribution, possibly showing different potential for natural and/or anthropogenic dispersal. The bryozoan assemblages sampled along the coast of Lebanon include four of the six studied species, at least three of them presumably non-indigenous including M. harmeri Hayward, which displays a remarkably wide distribution from the Indian Ocean to the West Pacific and the East Atlantic (Canary Islands).

Four males, two females, five juveniles and nine post-larvae were collected with suprabenthic and epibenthic sledges from Le Danois Bank (Bay of Biscay) and the Galician waters. This uniunguiculate and brevitarsal species is defined by the following exclusive features: a tricuspidated ocular tubercle, T-shaped frontal part of the cephalon, lateral implantation of the cheliphores,particular denticulation of the chela fingers, the 4th palp article smaller than the 5th, and the presence of 2 or 3 cement gland tubes. These characters distinguish the species from its most similar species Nymphon tubiferum, and the new species is compared to other similar species within the same genus, namely N. caementarum, N. prolatum, N, puellula and N. caldarium.

They are Paraisoannulus machiles gen. nov. and sp. nov. on Machilus gam-blei King ex Hook. f. (Lauraceae), Pentacecidophyes xinglongis gen. nov. and sp. nov. on Litchi chinensis Sonn. (Sapin-daceae) and Paracaridilophus retusus gen. nov. and sp. nov. on Fissistigma retusum (Levi.) Rehd. (Annonaceae). All the new species described herein arevagrants on their respective host plant.

The worldwide distribution of the 16 species we found is updated, from which, 15 species are new records as epibionts of 15 species of aquatic true bugs. Only for the suctorian Discophrya gessneri Matthes, we confirm the previous record (epibiont of Aphelocheirus aestivalis Fabricius). We conclude that the relationship between the suctorians and aquatic true bugs is poorly studied and some suctorian genera (Discophrya Lachmann and Periacineta Collin) inhabit as nepomorphans as other aquatic insects (Coleoptera). However the high degree of specificity at the species level ofthese genera is evident, for which we provide some possible explanations according to the group of basibiont.

查看更多>>摘要：The genus Melychiopharis Simon was originally described in the family Araneidae, placed close to Hypognatha Guerin-Meneville (Simon 1895: 907). Levi (2002) transferred the genus to Theridiidae, based on its unusual morphology, which is extremely different from the araneid body plan. However, Santos et al. (2005) presented evidence suggesting that this genus is closer to araneid genera, like Hypognatha and Testudinaria Taczanowski and, consequently, transferred it back to Araneidae. That study also included a redescription and illustrations of the genus and of its only species, M. cynips Simon, 1895, which is currently known from northern, central and northeastern Brazil.

The specimens are deposited in the Coleccion Boliviana de Fauna, La Paz (CBF 6453) and in the National Museum, Prague (NMP6V 74059). Because species identification within Hyalinobatrachium based only on morphological characters is in many cases problematic (Kok & Castroviejo-Fisher 2008; Castroviejo-Fisher et al. 2009), we took advantage of published sequences of Hyalinobatrachium to identify our samples. Our results show that each specimen belongs to a different species {H. mondolfii and H. munozorum),none of them previously known to occur in Bolivia. The taxonomic implications of our discovery are briefly discussed.
