Molecular Dataset

We reconstruct a phylogenetic framework for the zygopteran family Lestidae based on a molecular dataset comprised of sequence data from the genes COI, 16S, 18S, 28S, and ITS1+2 from 41 ingroup taxa and 8 outgroup taxa with emphasis on the systematic position of the genus Chalcolestes Kennedy. We recover Lestidae as monophyletic with good statistical support. The family falls into two subequal clades. One, comprising the genus Sympecma Burmeister and Lestes Leach sensu lato (including the genus Archi­lestes Selys) is poorly to moderately supported. While the other, comprising the genera Austrolestes Tillyard, Indolestes Fraser, Orolestes McLachlan, and Chalcolestes is strongly supported. Chalcolestes is recovered as sister to the Oriental genus Orolestes with strong support. Our results thus support that Chalcolestes is a valid genus not closely related to Lestes. Monophyly of Lestes requires inclusion of the New World genus Archilestes, and our results support the need for a thorough revision of Lestes.

A new sponge collected from 2,024 m depth on the Vance Seamount in the north-east Pacific by the ROV ‘Tiburon’ is described in the family Cladorhizidae as a new genus and new species, Lollipocladia tiburoni. The sponge, 112 mm in total height, is in the shape of a pedunculate disc, like several cladorhizid sponges of the genera Abyssocladia and Neocladia. It differs from these genera and from all carnivorous poecilosclerids by its microsclere complement, consisting of palmate isochelae, sigmancistras, and strongly curved anchorate isochelae superficially resembling those of Neocladia. A re-examination of the holotype of Neocladia indicates that it is a valid genus different from Chondrocladia.

Nuttall and Warburton (1911, pp. 105–13) give a detailed account of the systematic survey of the family Ixodidae and recognise nine genera in the family. They consider Aponomma Neumann as a subgenus of Amblyomma Koch, but I consider it a valid genus.

Abstract. Kirkbyites upsoni Johnson, 1936 from the Upper Pennsylvanian of North America, type species of the poorly understood genus Kirkbyites, corresponds significantly with the well-known species Kullmannissites? solus Becker, 1981 from the Upper Devonian of SW Europe. From common, important diagnostic characters, the latter is considered to be a species of Kirkbyites Johnson, 1936 which is a valid genus of the Family Amphissitidae Knight, 1928 (Ostracoda, Palaeocopida, Kirkbyacea).

Hells Canyon

Two Upper Triassic sphinctozoan sponges of the family Sebargasiidae were recovered from silicified residues collected in Hells Canyon, Oregon. These sponges areAmblysiphonellacf.A. steinmanni(Haas), known from the Tethys region, andColospongia whalenin. sp., an endemic species. The latter sponge was placed in the superfamily Porata by Seilacher (1962). The presence of well-preserved cribrate plates in this sponge, in addition to pores of the chamber walls, is a unique condition never before reported in any porate sphinctozoans. Aporate counterparts known primarily from the Triassic Alps have similar cribrate plates but lack the pores in the chamber walls. The sponges from Hells Canyon are associated with abundant bivalves and corals of marked Tethyan affinities and come from a displaced terrane known as the Wallowa Terrane. It was a tropical island arc, suspected to have paleogeographic relationships with Wrangellia; however, these sponges have not yet been found in any other Cordilleran terrane.

Information concerning the morphology and replication of organism of the family Mycoplasmataceae remains, despite over 70 years of study, highly controversial. Due to their small size observations by light microscopy have not been rewarding. Furthermore, not only are these organisms extremely pleomorphic but their morphology also changes according to growth phase. This study deals with the morphological aspects of M. pneumoniae strain 3546 in relation to growth, interaction with HeLa cells and possible mechanisms of replication.The organisms were grown aerobically at 37°C in a soy peptone yeast dialysate medium supplemented with 12% gamma-globulin free horse serum. The medium was buffered at pH 7.3 with TES [N-tris (hyroxymethyl) methyl-2-aminoethane sulfonic acid] at 10mM concentration. The inoculum, an actively growing culture, was filtered through a 0.5 μm polycarbonate “nuclepore” filter to prevent transfer of all but the smallest aggregates. Growth was assessed at specific periods by colony counts and 800 ml samples of organisms were fixed in situ with 2.5% glutaraldehyde for 3 hrs. at 4°C. Washed cells for sectioning were post-fixed in 0.8% OSO4 in veronal-acetate buffer pH 6.1 for 1 hr. at 21°C. HeLa cells were infected with a filtered inoculum of M. pneumoniae and incubated for 9 days in Leighton tubes with coverslips. The cells were then removed and processed for electron microscopy.
