A New Species

A new species of symbiotic palaemonid shrimp, Periclimenaeus mcmichaeli sp. nov., is described based on a single male specimen collected near Dry Tortugas, Florida, in the southeastern Gulf of Mexico. This new species, the 14th now known for the genus Periclimenaeus Borradaile 1915 from the western Atlantic, is morphologically most similar to P. wilsoni (Hay, 1917), from which it can be separated by the presence in the new species of two small subdistal teeth on the ventral margin of the rostrum, absence of small spinules or tubercles on ventral margin of the meri of the major and minor chelipeds, presence of three teeth on the cutting edge of the dactylus of the minor chela, and position of dorsal spines on the telson. The presence in this new species of a prominent acute projection on each pleurae of the third and fourth somite is documented, and appears to be a character previously overlooked in the taxonomic literature of species of the genus. This new species is compared with other similar congeners from the western Atlantic as well as other oceanic regions. An updated diagnosis for P. wilsoni, and a key to identify the western Atlantic species of the genus, are also presented.

A New Species

A new species of spider crab, Hemus magalae n. sp. (Majidae), is described from a single male specimen from Islas de las Perlas, Pacific Ocean coast of Panamá. This species differs from its congeners with respect to many features of the carapace including mid-line elevation and lateral dentition. Hemus A. Milne-Edwards, 1875, now includes four species, three from coastal waters of the eastern Pacific Ocean and one from shallow waters in the tropical western Atlantic Ocean. A key to the Pacific and Atlantic species of Hemus is provided.

A New Species

A new species of axiid was discovered during sampling offshore deep banks on the middle continental shelf off Louisiana. Paraxiopsis kensleyi n. sp. appears to inhabit interstices and cavities of coralline algal rubble, rhodoliths, coral rubble, and other eroded calcareous substrates. Weakly separated from Eutrichocheles Wood-Mason, 1876 on the basis of morphology, present assignments of western Atlantic species to Paraxiopsis de Man, 1905 are regarded as provisional. The new species is described morphologically, and the coloration of freshly captured specimens is documented and compared to related species where possible. Coloration readily distinguishes mature specimens of the new species from Paraxiopsis spinipleura Kensley, 1996, with which it was initially confused. The diagnosis includes GenBank accession numbers for COI sequences to allow future molecular phylogenetic comparisons. Compared to regional species that share a similar dentation or spination on the submedian carina, the pleon of the new species is distinctive in the truncate ventral margin on pleura 2–4, as opposed to being broadly rounded or directed ventrally in an acutely triangular tip. The new species is the eighteenth species of Paraxiopsis worldwide and the ninth from western Atlantic waters, seven of which are now known to range into the Gulf of Mexico. An updated key to western Atlantic members of the genus is provided.

A New Species

All previous records of Pachycheles rugimanus A. Milne-Edwards, 1880, from the Brazilian coast are reviewed and prove to represent a new species, P. coelhoi sp. nov. (from Amapá, northern Brazilian coast), and P. ackleianus A. Milne-Edwards, 1880, a species already known from Brazil (from Pará to Rio de Janeiro). The new species is described and illustrated, and compared to its most similar congeners: P. rugimanus and P. ackleianus from the western Atlantic, and P. velerae Haig, 1960, from the eastern Pacific (Galapagos Island and Cocos Island). Pachycheles coelhoi sp. nov. is distinguishable from the other three species by a suite of morphological characters, which include the ornamentation of the carapace and chelipeds, and the shape of the third thoracic sternite. All previous records of P. rugimanus from Brazil are considered invalid.

A new species of Amphiesma is described from the Truong Son (Annamite mountain range) of Quang Binh Province in central Vietnam. This new species is characterized by the combination of the distinct coloration and pattern, the slender body and tail (tail/total length ratio 0.31), the large eye diameter, a single loreal and preocular, three postoculars, a single anterior and posterior temporal, nine supralabials (fourth to sixth reach the eye), nine infralabials, 179 ventrals (plus two preventrals), anal plate divided, 99 divided subcaudals, dorsal scales in 19-19-17 keeled rows, 34 maxillary teeth (the two posteriormost enlarged), hemipenis simple, with undivided sperm groove, covered with small spines except for a single, strongly enlarged spine next to the sperm groove at the hemipenis base and except for irregularly arranged medium-sized spines that encircle the organ horizontally at the trunco-pedicel area. The new taxon is known only from a single male specimen that was collected in a limestone forest valley.

A New Species

The recently described dung beetle tribe Byrrhidiini currently comprises seven genera and nineteen species (Davis et al. 2019). During a recent collecting expedition to the Brandberg Mountain [S21.11° E14.69°] in Namibia, a single male specimen, together with various disarticulated body parts of a new species belonging to this tribe were collected. It was found amongst dried hyrax (Procavia capensis) dung pellets between large granite boulders. This new species clearly fits the current definition of the genus Versicorpus Deschodt, Davis & Scholtz, 2011. This raises the number of the constituent species of Versicorpus to three and that for Byrrhidiini to twenty.

A New Species

Microprosthema semilaeve, a fairly common spongicolid shrimp of reefal habitats in the Western Atlantic and Caribbean is redescribed and figured based on type material and an additional 78 specimens from the majority of its known zoogeographical range. It is distinguished from the Indo-Pacific species of M. validum and an undescribed species of Microprosthema with which it has been confused in the literature by a number of morphological characters. A new species of Microprosthema from deeper waters off the Dry Tortugas and closely related to M. inornatum Manning & Chace, 1990, is described and illustrated. Microprosthema jareckii Martin, 2002 is synonymized with M. manningi Goy & Felder, 1988. A key to the Western Atlantic species of Microprosthema is presented.

A New Species

The species described as new is placed in the genus Adelencyrtus, Ashmead, provisionally. The description is published at this time to provide a name, so that biological information concerning the species can be made a matter of record. The new species is most closely allied to Adelencyrtus. It differs from typical species of this genus with regard to the mandibles. In typical Adelencyrtus the mandibles are quadridentate, and the ventral margin is provided with a stout, cone-shaped seta. In the new species only the ventral tooth is distinct; the dorsal margin of the cutting edge appears as a wide truncation, which can scarcely be described as subdivided, and the ventral margin of the mandible lacks the stout conical seta. The most useful character for the identification of this species, and the one which reveals its relationship to Adelencyrtus most surely, is the distinctive male antennae. In this sex the antennal club is enormously cylindrically elongated, and the funicle is composed of two vestigial segments that are contained in a recess at the base of the club. Antennae of a similar kind have been described in the males of Habrolepis, Förster and Anabrolepis, Timberlake, two genera which are closely allied to Adelencyrtus. The males of Adelencyrtus have not been described.

A New Species

Astrophiura caroleae, new species, is described from off Curacao in the southern Caribbean, and from the western Gulf of Mexico, in depths of 244 to 434 meters. This new species, the first in the genus Astrophiura to be described from the Atlantic Ocean, has a distinctive combination of characters, including regularly arranged primary plates, large radial shields whose radial edges are in contact for their entire visible length, and prominent tubercles on central and radial plates. The mottled reddish coloration of the dorsal surface of this species usually contrasts with the color of the substratum, rendering it readily visible in situ, despite its disc diameter of less than 10 mm. Like its congeners, A. caroleae is gonochoric, the gonads of females containing conspicuous masses of bright orange eggs that are approximately 165 µm in diameter. DNA Barcoding data are provided for this new species, these are the first for Astrophiura.
