Belongs within: Mediophyceae.Contains: Stephanodiscus. Thalassiosira is a genus of centric diatoms found primarily in marine waters, with some species found in fresh water. The genus is probably not monophyletic with other genera nested within it (Alverson et al. 2007). Characters (Spaulding & Edlund 2008): Valve face flat or tangentially undulate; fultoportulae one to several near the center valve;… Continue reading Thalassiosira

Microtrombidium
Belongs within: Microtrombidiidae. Microtrombidium is a cosmopolitan genus of predatory mites, primarily recognised from adults with the larva of M. nitidum only described in 1994. Though numerous species have been assigned to the genus historically, the position of many requires further assessment (Southcott 1994). The European effective type species M. pusillum is characterised by as… Continue reading Microtrombidium
Microtrombidiidae
Belongs within: Trombidioidea.Contains: Enemothrombium, Eutrombidium, Camerotrombidium, Manriquia, Trombiculidae, Microtrombidium, Platytrombidium. The Microtrombidiidae are a cosmopolitan group of predatory mites with the palptibia of adults bearing multiple spinose setae alongside the terminal claw, and with larvae parasitic on Diptera. A large plate is present posteriorly on the idionotum in adults of the subfamily Eutrombidiinae but absent… Continue reading Microtrombidiidae
Hyolitha
Belongs within: Tannuolinidae.Contains: Circothecida, Orthothecida, Sulcavitida, Hyolithidae, Crispatellidae. Hyoliths were a group of small shelled animals that mostly lived during the Cambrian and Ordovician (though probable hyoliths remained alive as late as the Permian—Peel & Yochelson 1984). They possessed a bilaterally symmetrical conical shell that was open at one end only and closed by an… Continue reading Hyolitha
Platytrombidium
Belongs within: Microtrombidiidae. Platytrombidium is a genus of predatory mites known from adults only. The larva is as yet unidentified unless, as is quite possible, this genus is synonymous with the related Atractothrombium. Body hairs are short and thick, covered with short, fine setules (Southcott 1994). Mites in red velvet Published 22 December 2015 Mites… Continue reading Platytrombidium
Scoliostomatidae
Belongs within: Gastropoda. The Scoliostomatidae are a Devonian family of gastropods with a distinctive shell morphology: at maturity, the last whorl of the shell twists outwards and backwards, so its apparent position is reversed relative to the rest of the shell. This gerontic whorl also turns upwards in members of the subfamily Scoliostomatinae but not… Continue reading Scoliostomatidae
Gastropoda
Belongs within: Mollusca.Contains: Scoliostomatidae, Caseolus, Leiostyla, Clisospiroidea, Bellerophontoidea, Archinacelloidea, Pelagielloidea, Macluritida, Neomphaliones, Patellogastropoda, Vetigastropoda, Neritimorpha, Loxonematoidea, Heterobranchia, Peruneloidea, Cyclophoroidea, Ampullariidae, Viviparoidea, Orthonematoidea, Subulitoidea, Soleniscidae, Meekospiridae, Cerithiimorpha, Hypsogastropoda. The Gastropoda, snails and slugs, are a major clade of molluscs characterised by the process of torsion during larval development with the visceral mass and mantle becoming turned… Continue reading Gastropoda
Acmaeidae
Belongs within: Patellogastropoda. The Acmaeidae are a group of conical limpets found in the North Pacific. Living members of the family have a radula with three pairs of uniform lateral teeth (Nakano & Ozawa 2004). In the genus Acmaea, the apex of the shell is mostly subcentral and the muscle impressions are joined by a… Continue reading Acmaeidae
Sphagnales
Belongs within: Bryophyta.Contains: Sphagnum subgenus Sphagnum. The Sphagnum mosses are, together with the Tasmanian Ambuchanania leucobryoides, the sister group to all other living mosses. They have thalloid protonemata, leafy shoots lacking rhizoids, and the capsules are not held above the gametophytes by a seta but by an extension of the gametophyte itself called the pseudopod.… Continue reading Sphagnales
Agrostis
Belongs within: Pooideae. Agrostis, the bentgrasses, is a genus of about 200 species of grasses found in temperate and tropical montane regions of the Northern Hemisphere. Many bentgrasses are widely used in lawns. These include the creeping bentgrass A. stolonifera, which is native to Eurasia and northern Africa and has been widely introduced in other… Continue reading Agrostis
