Potamocypris steueri is a species of ostracod crustaceans in the family Cyprididae, subfamily Cypridopsinae found in marine brackish waters of the Mediterranean Basin as well as in brackish coastal waters of the Black Sea and the Caspian Sea.
The carapace of P. steueri appears subovate in lateral view. It is light green with four dark green transverse stripes. The length ranges from 0.55 to 0.68 mm, with females being slightly larger than males.
The second antennae carry swimming setae that slightly extend beyond the tips of the terminal claws. [1]
Antennae, sometimes referred to as "feelers", are paired appendages used for sensing in arthropods.
Mysida is an order of small, shrimp-like crustaceans in the malacostracan superorder Peracarida. Their common name opossum shrimps stems from the presence of a brood pouch or "marsupium" in females. The fact that the larvae are reared in this pouch and are not free-swimming characterises the order. The mysid's head bears a pair of stalked eyes and two pairs of antennae. The thorax consists of eight segments each bearing branching limbs, the whole concealed beneath a protective carapace and the abdomen has six segments and usually further small limbs.
Cherax parvus is a species of crayfish in the family Parastacidae. It is only known from its type locality – the Upper Tully River catchment in the Cardwell Range of north-eastern Queensland – and is listed as data deficient on the IUCN Red List. It was discovered in a rainforest catchment in a highland of northeastern Queensland during a Queensland Museum expedition to the upper Tully River area in November 1992. It is one of the smallest species in the genus. No species of Cherax has been considered endemic to wet upland or highland areas before it was discovered; most previous records were from elevations less than 400 meters. It also has several morphological features unique to the genus, and does not appear closely related to any extant species, suggesting a long period of geographic isolation.
Goneplax rhomboides is a species of crab. It is known by the common name angular crab because of its angular carapace. Although it is also called the square crab, its shell is in fact more trapezoidal than square. This species is also known as the mud-runner because they are able to run away quickly when threatened.
Electromyrmococcus is an extinct genus of mealybug in the Pseudococcidae subfamily Rhizoecinae. The genus currently contains three species, all from the early Miocene, Burdigalian stage, Dominican amber deposits on the island of Hispaniola.
Nototropis falcatus is a species of amphipod crustacean. It is whitish in colour, with brown patches, and grows to a total length of around 7 mm (0.3 in). It lives on soft sediment such as fine sand at depths of 10 to 50 metres, from northern Norway to the west coast of Ireland, including the North Sea, and as far south as the southern Bay of Biscay.
Zophotermes is an extinct genus of termite in the Isoptera family Rhinotermitidae known from two Eocene fossils found in India. The genus contains a single described species, Zophotermes ashoki placed in the subfamily Prorhinotermitinae.
Nanotermes is an extinct genus of termites in the Isoptera family Termitidae known from only one Eocene fossil found in amber of the Cambay Basin. The genus contains a single described species, Nanotermes isaacae placed tentatively in the subfamily Termitinae.
Potamocypris is a genus of ostracod crustaceans in the family Cyprididae. There are currently 44 extant species of Potamocypris. The majority of the species occur in freshwater habitats; only a few species of the genus colonize marine brackish coastal waters.
Potamocypris mastigophora is a species of ostracod crustacean in the family Cyprididae, subfamily Cypridopsinae. It is known from Africa and the southern areas of the Palaearctic.
Potamocypris variegata is a species of ostracod crustaceans in the family Cyprididae, subfamily Cypridopsinae. It is mainly found in ponds with rich aquatic vegetation, more rarely in slowly flowing streams. The species is distributed throughout Europe, but is also known from North America.
Potamocypris unicaudata is a species of ostracod crustacean in the family Cyprididae, subfamily Cypridopsinae. It is abundantly found in ditches and ponds near the sea shore, where freshwater slightly mingles with sea water. It is known from both Europe and North America.
Potamocypris smaragdina is a species of ostracod crustacean in the family Cyprididae, subfamily Cypridopsinae. It is known from both Europe and North America.
Potamocypris arcuata is a species of ostracod crustacean in the family Cyprididae, subfamily Cypridopsinae. It is mainly known from the southern areas of the Palaearctic.
Elephantomyia (Elephantomyia) pulchella is an extinct species of crane fly in the family Limoniidae. The species is solely known from the Middle Eocene Baltic amber deposits in the Baltic Sea region of Europe. The species is one of six described from Baltic amber.
Gerontoformica is an extinct genus of stem-group ants. The genus contains thirteen described species known from Late Cretaceous fossils found in Asia and Europe. The species were described between 2004 and 2016, with a number of the species formerly being placed into the junior synonym genus Sphecomyrmodes.
Bradoponera is an extinct genus of ant in the Formicidae subfamily Proceratiinae, and is one of four genera of the subfamily. The genus contains four described species Bradoponera electrina, Bradoponera meieri, Bradoponera similis, and Bradoponera wunderlichi. The species are known from several Middle Eocene amber fossils which were found in Europe.
Boltonimecia is an extinct genus of ant in the formicid subfamily Zigrasimeciinae. The genus contains a single described species, Boltonimecia canadensis, and is known from a single Late Cretaceous fossil which was found in Canada. The type species was originally described as a species of the extinct genus Sphecomyrma under the combination Sphecomyrma canadensis.
Portunus segnis, the African blue swimming crab, is a species of crustacean, a swimming crab belonging to the family Portunidae. While native to the western Indian Ocean, it is also invasive in the Mediterranean. It is thought to have come through the Suez Canal from the Red Sea but it may have been transported by ships.
Ankothrips yuccae is a species of thrip in the family Melanthripidae. Its host plant is Yucca whipplei.
