Belongs within: Mangeliidae. Dazed and Cythara Published 19 August 2026 I’ve had occasion multiple times on this site to comment on the taxonomic complications surrounding the conoid gastropods, ‘turrids’ in the broad sense. Nevertheless, among the more complicated cases is that of the genus name Cythara. Cythara striata was established by Christian Schumacher in 1817 for a… Continue reading Eucithara

Philosciidae
Belongs within: Crinocheta. The Philosciidae are a family of woodlice in which the pleon is narrower than the pereion, resulting in a more or less apparent discontinuity in the body outline (Vandel 1973). <==Philosciidae |–AphilosciaV73 |–OreadesV73 |–IschiosciaV73 |–ProischiosciaV73 |–Paraphiloscia hammeniV73, H83 |–Rennelloscia cycloopiV73, H83 |–SetaphoraV73 |–PseudophilosciaV73 |–ZebrasciaV73 |–ColombophilosciaV73 |–NesophilosciaV73 |–DidimaV73 |–NahiaV73 |–HelenosciaV73 |–DekanosciaV73 |–HeroldiaV73 |–Metriogastor Vandel… Continue reading Philosciidae
Porcellio
Belongs within: Crinocheta. Porcellio is a cosmopolitan genus of woodlice with a two-segmented flagellum and tracheae in only the first two or three pleopods (Hatch 1947). Characters (Hatch 1947): Body not at all contractile into a ball; median lobe of head rounded, median line below not carinate; front of head without obtusely angulate carina in front of frontal… Continue reading Porcellio
Cubaris
Belongs within: Armadillidae. Cubaris is a cosmopolitan genus of woodlice with poorly differentiated volvation structures (Vandel 1973). Characters (Vandel 1973): Head with face extending upwards into low, slightly projecting frontal blade; frontal shield recognizable though poorly defined; secondary marginal line continuous, on each side, with frontal margin. Pronotum large, surface area equal to one-fifth, or even one-quarter, of… Continue reading Cubaris
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
Monoplacophora
Belongs within: Mollusca.Contains: Kirengellida, Tryblidiida, Cyrtolitidae. The Monoplacophora are a group of molluscs with simple, often cap-shaped shells and an exogastric, untorted organisation. Living representatives exhibit internal metamerism, which may be represented in fossil forms by a series of pairs of muscle scars. <==Monoplacophora | i. s.: Pseudomyona queenslandicaBRW98 |–Tergomya [Pilinea]BR17 | |–KirengellidaBR17 | `–TryblidiidaBR17 |–Cyrtonellidae [Cyrtonellacea,… Continue reading Monoplacophora
