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.
Glyphoderma is an extinct genus of placodont reptile from the Middle Triassic of China. It differs from its relative Psephochelys in having three, rather than one, fused osteoderms on the posterior skull surface, and has an earlier temporal range, from the Ladinian epoch rather than the Late Triassic. Otherwise, it is similar in most respects to the other plachochelyids found in China. The name comes from the Greek 'γλυφος', 'sculpture' and 'δερμα', 'skin' referring to its unique carapace structure. The specific name honours a Mr. Kang Ximin.
Oregonia bifurca, commonly known as the split-nose crab or the split-nose decorator crab, is a species of crabs belonging to the family Oregoniidae. It is a rare deep-water species that inhabits the tops of seamounts and guyots in the northeastern Pacific Ocean; from the Aleutian Islands, the Bering Sea, the Hawaiian–Emperor seamount chain, to the waters off British Columbia. It is closely related to the more common shallow-water species Oregonia gracilis, the graceful decorator crab.
Procaris hawaiana is a species of shrimp in the family Procarididae, from Maui, Hawaii. The species is very similar to Procaris ascensionis from Ascension Island. In P. ascensionis the integument is less firm, the rostrum is shorter, the cervical groove is more distinct, and the third abdominal somite reaches less far posteriorly over the fourth; also the scaphocerite has the final tooth still less distinct than in P. hawaiana, and the last segment of its antennal peduncle is less slender.
Palaemonella burnsi is a species of shrimp in the family Palaemonidae, from Maui, Hawaii. This species is closest to Palaemonella lata, which it resembles in the broad scaphocerite in which the lamella overreaches the final tooth, and in the unarmed merus of the second pereiopods. It differs from P. lata in the much longer fused part of the two branches of the upper antennular flagellum, in the relatively much longer fingers and shorter palm of the second legs, in the unarmed carpus of the second legs. It is named after John A. Burns, Governor of Hawaii, for declaring the Ahiki Kinau area a nature reserve.
Periclimenes pholeter, is a species of shrimp belonging to the family Palaemonidae. The species is closest to Periclimenes indicus, P. obscurus and P. toloensis, resembling these species in the presence of an epigastric tooth on the carapace, the shape of the abdomen, the spinulation of the carapace, and the unarmed fingers of the first chelipeds. P. pholeter most resembles P. indicus by the elongatecarpus and long fingers of the second pereiopods, differing in these features from P. toloensis, which has the fingers slightly less than half as long as the palm. In P. obscurus the fingers are shorter than the palm, but the carpus is about as long as the palm. From P. indicus, this species differs: by the greater size; by the much higher rostrum and the greater number of ventral rostral teeth; by the shorter eye; by the less slender antennular peduncle; by the more deeply cleft upper antennular flagellum; by the more robust scaphocerite; by the fingers of the first pereiopods ; by the more slender pereiopods, especially the fifth, which is much longer than the ischium.
Chaceon bicolor is a species of crab. Chaceon bicolor differs from all species of the genus in color pattern, with the anterior part of the body purplish rather than reddish. In addition to color pattern, C. bicolor also differs from C. granulatus in having compressed rather than depressed dactyli on the walking legs; also, the hepatic region of the carapace in C. granulatus is coarsely granular, whereas it is smooth in C. bicolor. Juvenile specimens differ from adults in many features: the teeth of the carapace are much larger and sharper, there is a sharp spine on the carpus of the cheliped and a distal spine on the merus of each walking leg, plus the legs are longer and slenderer. Adult females differ from males in having much sharper anterolateral teeth on the carapace, sharper suborbital spines, and much shorter legs, with less trace of a distal dorsal projection on the merus. The carapace of females is more strongly arched from front to back and the protogastric regions are noticeably more inflated. The species is named as such because of its colour patter, purple an tan.
Chaceon atopus is a species of crab. This species resembles C. gordonae, from the Cape Verde Islands and Sierra Leone, in many features: its large size, well-developed frontal and
Synalpheus microneptunus is a species of small snapping shrimp native to the waters off the island of Barbados. It is one of at least seven known species of eusocial shrimp. They are cryptofauna, living exclusively within the network of tunnels in the sponges Neopetrosia proxima and Neopetrosia subtriangularis. They form small colonies of six to fifteen individuals, usually with only a single breeding female.
Lauridromia is a genus of crabs in the family Dromiidae. It contains only two species. At one time a third species, Lauridromia indica, was included in the genus but that has now been transferred to the genus Dromidiopsis as Dromidiopsis indica.
Salvatoria pilkena is a species belonging to the phylum Annelida, a group known as the segmented worms. The species name comes from an Aboriginal word, pilkena, meaning "different", due to its characteristic features. Salvatoria pilkena belongs to a reduced group of species that possess rugose dorsal cirri, contrary to the typical spindle-shaped cirri found in its genus. It also lacks dorsal cirri on chaetiger 2. It resembles Salvatoria swedmarki and S. celiae, differing from pilkena in that the latter has significantly longer proventricles, while its compound chaetae are short and unidentate. At the same time, S. opisthodentata has a similar body and compound chaetae but appears to possess dorsal cirri on its chaetiger 2.
Alpheus tricolor is a crustacean belonging to the family of snapping shrimp. It was first isolated in Indonesia and Sri Lanka. It counts with a setose carapace, an acute rostrum, shallow adrostral furrows and a basicerite with a strong ventrolateral tooth. The lamella of its scaphocerite is not reduced, with an anterior margin that is concave. Its third maxilliped counts with an epipodial plate bearing thick setae, while its first chelipeds are found with their merus bearing a strong disto-mesial tooth; its third pereiopod has an armed ischium, with a simple and conical dactylus. Its telson is broad, distally tapering, with 2 pairs of dorsal spines. The species is named after its characteristic colour pattern, including white, red and orange.
Alpheus fasqueli is a crustacean belonging to the family of snapping shrimp. It was first isolated in Sri Lanka. It counts with a setose carapace, an acute and carinate rostrum, and unarmed orbital hoods. Its basicerite has a strong ventrolateral tooth. The lamella of its scaphocerite is not reduced. Its third maxilliped counts with an epipodial plate bearing thick setae, while its first chelipeds are found with their merus bearing a strong disto-mesial tooth; its third pereiopod has an armed ischium, with a simple and conical dactylus. Its telson is broad, distally tapering, with 2 pairs of dorsal spines. The species is named after Frédéric Fasquel, a photographer who contributed rare shrimp specimens for the Muséum national d'histoire naturelle.
Scutarx is an extinct genus of Aetosauriformes, most commonly regarded by its species name Scutarx deltatylus. Scutarx lived around 230 million years ago during the Carnian and Norian stage of the Late Triassic. Scutarx are “medium sized” paramedian osteoderms belonging to the clade Aetosauria, a heavily armored and more herbivorous cousin of crocodiles.
Charybdis hellerii, the Indo-Pacific swimming crab or spiny hands is a species of crab from the swimming crab family, the Portunidae. Its native range covers the Indian and Pacific Oceans but it has been introduced to the western Atlantic and has invaded the Mediterranean. It is a commercially exploited species in south-east Asia.
Torbenella calvata is a species of squat lobsters in the family Munididae. The species name, calvata, comes from the Latin word calvatus, meaning made bare. This is in reference to its lack of spines on the anterior ridge of the second abdominal segment.
Eucrate crenata, the blunt-spined euryplacid crab, is a species of Indo-Pacific crab from the family Euryplacidae. It has invaded the Mediterranean Sea from the Red Sea by Lessepsian migration through the Suez Canal.
