A New Species

A new species—Docosia caucasica sp. n.—has been described from material collected from the Lesser Caucasus Mountains in Georgia (Sakartvelo). The new species belongs to a group of Palaearctic species characterized by distinct posterolateral processes of gonocoxites and apically modified setae at the posteroventral margin of the gonocoxites medially. Within the group, D. caucasica sp. n. is most similar to D. landrocki Laštovka and Ševčík, 2006 in having a similar outline of the medial process of posteroventral margin of the gonocoxites and the gonostylus. There is also a marked difference within the partial cytochrome c oxidase subunit 1 gene (COI) sequence of D. caucasica sp. n. and other Docosia spp. available in public databases. As the new species is described from a single male specimen only, the adequacy and code compliance of that are discussed.

A New Species

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 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.

Comprehensive Studies

In 2019, the authors of the present paper presented a detailed study on the genus Diarsia Hübner, 1816, giving an overview on the distribution, research history and the comprehensive studies and generic classification of the genus, including the description of seven new species (Gyulai & Saldaitis, 2019). In that paper, one of the newly described species was Diarsia zillii Gyulai & Saldaitis, 2019, based on a single male specimen. Since, a further male and a female were found in the collected stored material, almost from the same locality and date. The genitalia dissection confirmed that the description was necessary and correct. Thus, the colour image of the female and the short characterisation of the female genitalia are given in the present paper.

A New Species

A new species of the natricine snake genus Hebius Thompson, 1913 is described from Sichuan Province, Southwest China, based on a single male specimen. The new species is distinguished from its congeners found in China and adjacent regions by possessing the following combination of characters: 1) TL/SVL ratio 0.35; 2) three postoculars; 3) six temporals in formula 1/(1+1) +1+2; 4) eight supralabials, 4th and 5th in contact with the eye, 6th supralabial largest; 5) ten infralabials with the first five bordering the anterior chinshields; 6) 172 ventrals (plus two preventrals); 7) cloacal plate divided; 8) 90 divided subcaudals; 9) dorsal scales in 19-19-17 rows, all weakly keeled except the outer two; 10) reduction of dorsal scale rows from 19 to 17 at the position above ventral scale 99th; 11) reduction of the tail dorsal scales from 8 to 6 rows at the position above 18th subcaudal, and from 6 to 4 rows at the position above 37th subcaudal; 12) postorbital bones do not touch frontals, the parietal ridge weakly developed; the end of the supratemporal bones extending beyond the braincase; maxillary teeth 23–25, the last two enlarged, without diastema between them and the anterior teeth. This species is an evergreen forest dweller.

A new species of Texella, T. martensi n. sp., is described on the basis of a single male specimen from Titus Canyon Cave, Inyo County, California. The species belongs to the kokoweef group in having a spur on trochanter IV and lacking a postopercular process on the abdomen. Texella martensi n. sp. is the most troglomorphic of the four species of Texella now recorded from the Mojave Desert and it is the northernmost member of the group.

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.

Recent taxonomic studies on the genus Wahydra Steinhauser, 1991, have described five new species in the past two years, from high elevations in the Andes Mountains. A markedly distinct species of Wahydra is herein described and illustrated based on a single male specimen from Ecuadorian Andes, Wahydra graslieae A. Warren, Carneiro & Dolibaina, sp. nov. The new species is compared with other species of Wahydra, as well as with the somewhat similar species Lerema viridis (Bell, 1942) and Tigasis viridenex (Weeks, 1901).

A new species of the laomediid mud shrimp genus Naushonia Kingsley, 1897, N. kiiensis, is described and illustrated on the basis of a single male specimen from Kii Peninsula, central Japan, at a sublittoral depth of 14 m. The new species is morphologically closest to N. serratipalma Komai & Anker, 2010, known from French Polynesia and the Red Sea coast of Saudi Arabia, among the 15 known congeners, but is distinguished from the latter by the spinulose middorsal and submedian gastric carinae on the carapace, the rugose posterior dorsum of the carapace, stronger but fewer spines on the distomesial lobe of the pereopod 1 merus and fewer spinules consisting of the serration of the palm lateral margin. From Japanese waters three species have been recorded, of which only N. japonica Komai, 2004 is known from the temperate mainland. The new species is the second occurring in the Japanese mainland.
