The Tullbergiidae of Tibet is studied for the first time and the genus Metaphorura Bagnall, 1936 is firstly recorded in China. Metaphorura motuoensissp. n. from southeastern Tibet is described and illustrated. It is characterized by the presence of 1+1 pseudocelli on thoracic segment I, few vesicles (14 -16) on PAO, pseudocellar formula as 11/111/11111, all pseudocelli of type II, setae p4 on abdominal segment V as microsetae, weakly differentiated sensory seta p3 on abdominal segment V, absence of median process on Abd VI. In addition, Mesaphorura yosii (Rusek, 1967), Mesaphorura hylophila Rusek, 1982, and Prabhergia imadatei Tamura & Zhao, 1996 are recorded in Tibet for the first time. The type specimens of P. imadatei are re-examined and errors in the original description of chaetotaxy are corrected.

Alpheid Shrimp

Six rare or little-known genera from the shrimp family Alpheidae are reported from French Polynesia, five of them for the first time. Distribution ranges are significantly extended for the recently described Acanthanas pusillus Anker, Poddoubtchenko & Jeng, 2006 and Richalpheus palmeri Anker & Jeng, 2006, previously known only from two and one type specimens, respectively, from the Philippines. The original description of A. pusillus, based on two females, is completed with the description and illustration of the male cheliped and pleopod; accordingly, the diagnosis of Acanthanas is slightly emended. The genus Leptalpheus Williams, 1965 was not known from French Polynesia before, but is represented there by two species: L. denticulatus Anker & Marin, 2009, previously known from Vietnam, the Philippines and Fiji; and L. pacificus Banner & Banner, 1974, previously considered as a Hawaiian endemic. The genus Prionalpheus Banner & Banner, 1960 is represented in French Polynesia by two species: P. triarticulatus Banner & Banner, 1960, reported for the first time, and P. brachytomeus Banner & Banner, 1971, reported with some doubts (P. cf. brachytomeus) for the first time since the original description. Rugathanas borradailei (Coutière, 1903), a widespread but rather uncommon and easily overlooked species, is also reported for the first time from French Polynesia. Colour patterns are illustrated for all species, this being for the first time for R. palmeri, L. pacificus, P. triarticulatus and P. cf. brachytomeus.

AbstractMolecular and morphological characterization of two species of Cucullanidae from freshwater fish in Brazil are provided, one of which represented an undescribed taxon. Cucullanus opisthoporus n. sp. was collected in Cichla melaniae from River Xingu, State of Pará, and in C. pinima from River Jamarí, State of Rondônia. Nematodes referable to Cucullanus grandistomis were collected in Oxydoras niger from River Xingu. The new species has an appendage in the tail tip, ventrally covered by small spines, which is an exclusive feature of Cucullanus tucunarensis. However, C. tucunarensis differs from C. opisthoporus n. sp. based upon the relative position of deirids and the excretory pore, which are more posterior from the oesophageal end in the new species. Observations of C. tucunarensis type specimens also revealed features that were wrongly or not reported in the original description. Type specimens of C. grandistomis were observed, although they were poorly preserved. After evaluation of newly collected specimens of C. grandistomis, features unreported in the original description were observed for the first time, including the presence of an intestinal caecum. Thus, C. grandistomis was transferred to Dichelyne. Sequences of the 18S and 28S rRNA genes revealed high genetic similarity between the specimens of C. opisthoporus n. sp. from the two different hosts as well as their genetic distance from Dichelyne grandistomis n. comb. Phylogenetic reconstructions using representatives of Cucullanidae suggested the artificiality of the current morphological system adopted to separate the genera, since most genera were not monophyletic, although the availability of genetic data is still fragmented.

In this work we present a revision of the genus Ommatoiulus Latzel, 1884 in Portugal. Based on recently collected material and older museum samples, including type specimens, we describe six new species to science, viz. Ommatoiulus alacygni sp. nov., O. camurus sp. nov., O. denticulatus sp. nov., O. litoralis sp. nov., O. staglae sp. nov. and O. stellaris sp. nov. The species O. alacygni sp. nov., O. denticulatus sp. nov. and O. staglae sp. nov. described from the Algarve are outstanding by their extremely reduced mesomerital process. The species O. porathi (Verhoeff, 1893) and O. andalusius (Attems, 1927) are recorded and redescribed for the first time after their original description. The finding of O. andalusius – originally described from Andalusia in Spain – constitutes a new record for Portugal together with two species, viz. O. fuentei (Brolemann, 1920) and O. martensi Mauriès, 1969. The taxonomic status of several species is revised. Thus Archiulus (Schistocoxitus) cingulatus Attems, 1927 is here considered as a junior synonym of Ommatoiulus lusitanus (Verhoeff, 1895) while Schizophyllum cervinum Verhoeff, 1910 is synonymized with Ommatoiulus moreleti (Lucas, 1860). An identification key to all hitherto known Portuguese species of Ommatoiulus is presented as well as a distribution map illustrating the various species occurrences in the country.

The type specimens of fossil “Architectibranchia” and Cephalaspidea (Mollusca: Heterobranchia) deposited in the Academy of Natural Sciences of Philadelphia, USA, are listed herein. The collection includes types of circa 60 species, from the families: Acteonellidae, Acteonidae, Bullidae, Cylichnidae, Haminoeidae, Philinidae, Retusidae, Rhizoridae, Ringiculidae and Scaphandridae. The catalogue is presented in systematic order, with information on the original description, type locality, type stratum and age, catalog number in the collection, and current taxonomic status. Further taxonomic notes are offered when pertinent. Several species are illustrated here for first time. The new combinationsRoxaniahornii(Gabb, 1864) andVolvulellaminutissima(Gabb, 1860) are proposed. Some species that have previously been assigned to Acteonidae are revised here, resulting in the following new combinations:Odostomiamilium(Lea, 1846),Chrysallidasculpta(Lea, 1846) andPyrgulinaangulata(Lea, 1846). The list of taxa is also presented in other arrangements (alphabetically by specific epithets and by authorship and date) to facilitate locating information.

AbstractCucullanus bagre Petter, 1974 (Cucullanidae) is redescribed based on the examination of newly collected material and the revaluation of type specimens, using light and for the first time scanning electron microscopy. Parasite specimens were collected from the intestine of the coco sea catfish Bagre bagre (Linnaeus) (Ariidae) off the South Atlantic coast, State of Rio de Janeiro, Brazil. Detailed morphological analysis revealed the presence of an unpaired papilla just anterior to the cloacal protrusion in male, that was overlooked in the original description. Descriptions of the adult female and eggs are provided for the first time; these gravid specimens have the general morphometry quite similar to that of juveniles. Additionally, detailed description and illustration of sclerotized plates present on the oesophastome is provided. The far posterior location of the excretory pore with thick-walled excretory duct, the conspicuous protrusions present on both anal and cloacal regions and the number and arrangement of caudal papillae in males are considered to be important diagnostic features for C. bagre. All the specimens from type material were together in one vial and not separated in two vials as stated in the original description, making it impossible to determine which is the holotype, allotype or paratypes. This is the first report of C. bagre in Brazil, which expands its geographical distribution to South Atlantic waters.

The genus Actorthia Kröber, 1912 was described based on a single female from Tourrah (Egypt) and is revised for the first time since the original description. Actorthia khedivialis (Becker, 1912) is newly synonymized with A. frontata (Kröber, 1912) based on examination of the type specimens of both species recently discovered in the Cairo University Collection (Egypt) and Natural History Museum (Austria), respectively. Actorthia efflatouni Kröber, 1925 is confirmed as a synonym of A. micans (Kröber, 1923) and Actorthia olivierii (Macquart, 1840) is transferred to Phycus. Actorthia pulchella Kröber, 1927 is recorded in Israel for the first time. The three Egyptian species of Actorthia are diagnosed and illustrated along with colour images of the type specimens, and a key to the Egyptian species is included.

Japanese species of Microtendipes are reviewed. Eleven names proposed in this genus, including Russian M. sakhalinensis Zorina, 2001, are synonymized with M. umbrosus Freeman, 1955, for which male and female adults, pupa and larva are redescribed based on specimens collected from Japan. Two species, M. shoukomaki Sasa, 1989 and M. famiefeus Sasa, 1996, are validated based on the re-examination of type specimens and are redescribed based on specimens newly collected from Japan. Descriptions of the larva of M. shoukomaki and the female adult, pupa and larva of M. famiefeus are given here for the first time. Microtendipes chloris (Meigen, 1818) sensu Sasa is redescribed as a new species, M. parachloris Niitsuma & Tang sp. nov., based on the male adult. Additionally, synonymic notes of Polypedilum (Cerobregma) yamasinense (Tokunaga, 1940) comb. nov. and P. (Polypedilum) tsukubaense (Sasa, 1979), transferred from Microtendipes, are given. Polypedilum kamotertium Sasa, 1989 and M. iriocedeus Sasa & Suzuki, 2000 are synonymized with the above two species, respectively, based on each original description.         The distribution of M. umbrosus extends from Africa to the Russian Far East and East Asia (Japan, China), and Australia and Thailand (with new distributions reported here). Although no African type material is examined here, the morphological features of those populations are consistent with Freeman’s concept.

AbstractIn this talk I will show that multi-wavelength observations can provide novel constraints on the properties of ionized gas outflows in AGN. I will present evidence that the infrared emission in active galaxies includes a contribution from dust which is mixed with the outflow and is heated by the AGN. We detect this infrared component in thousands of AGN for the first time, and use it to constrain the outflow location. By combining this with optical emission lines, we constrain the mass outflow rates and energetics in a sample of 234 type II AGN, the largest such sample to date. The key ingredient of our new outflow measurements is a novel method to estimate the electron density using the ionization parameter and location of the flow. The inferred electron densities, ∼104.5 cm−3, are two orders of magnitude larger than found in most other cases of ionized outflows. We argue that the discrepancy is due to the fact that the commonly-used [SII]-based method underestimates the true density by a large factor. As a result, the inferred mass outflow rates and kinetic coupling efficiencies are 1–2 orders of magnitude lower than previous estimates, and 3–4 orders of magnitude lower than the typical requirement in hydrodynamic cosmological simulations. These results have significant implications for the relative importance of ionized outflows feedback in this population.
