A New Species

Upogebia hibiki sp. nov. (Gebiidea: Upogebiidae) is described from the Oligocene of northern Kyushu, Japan. The new species closely resembles U. mizunamiensis Karasawa 1989, but differs in having an arched ridge on the dorso-distal mesial surface of the palm of pereiopod 1. Additionally, the new species has a triangular rostrum and a narrow gastric region. The specimens are associated with fossil burrows assigned to the ichnogenus Psilonichnus Fürsich, 1981. Therefore, Psilonichnus described herein is thought to be formed by U. hibiki sp. nov.

A New Species

A new species of the mud-shrimp genus Axianassa Schmitt, 1924 is described based on four specimens collected in a muddy near-shore area inside the Moorea lagoon, Society Islands, French Polynesia. Axianassa ngochoae n. sp. constitutes the first Indo-West Pacific record of this genus, previously known only from the western and eastern coasts of the Americas. A key to all species of Axianassa is provided.

A New Species

A new species of the upogebiid mud shrimp genusAustinogebiaNgoc-Ho, 2001,A. liuin. sp., collected from the Bohai Sea, is described and illustrated. It is closely similar toA. takaoensis(Sakai & Türkay, 1995) andA. spinifrons(Haswell, 1881) in the fixed finger of the male pereopod 1 bearing a large blunt tooth on the outer (or lateral) surface, but differs markedly from the latter two in the rostrum being 1.7 times as long as its basal width, and the lower margin of the antennal peduncle being unarmed, respectively.

A New Species

A new species of mud shrimp of the genus Naushonia Kingsley, 1897 is described from two anchialine caves on the island of Great Abaco in the Bahamas. Naushonia tinkeri n. sp. is the fifteenth species in the genus and the second to be described from the Bahamas. The new species is morphologically similar to N. augudrea (Juarrero & García, 1997) from Holguín Province, eastern Cuba, with which it shares a carapace with cervical and cardiac grooves; however, it can be distinguished by having a pigmented cornea, the first pereiopod with a proportionately longer propodus and dactylus without a toothed external margin, and the telson longer relative to the uropod length. The new species inhabits anchialine caves and is the largest one reported until now.

A New Species

Ghost and mud shrimps in Axiidea and Gebiidea are hosts to parasitic epicaridean isopods, including species in Bopyridae and Ionidae. These isopods can reach high prevalence levels on their mud shrimp hosts and may strongly influence host ecology and biology. Currently, 54 species of bopyrids and eight species of ionids are known to parasitize ghost and mud shrimps. We present new taxonomic data on three species of ionids and ten species of bopyrids (nine previously described and one new to science), as well as on an undescribed species of nematode from an axiidean host. New locality and host records are given for all species. Our analysis of new material and review of museum specimens includes the description of the new species Acrobelione halimedae n. sp. from Austinogebia spinfrons (Haswell, 1881). We also provide an improved definition for the genus Pseudione Kossmann, 1881, based on morphological characters found in both sexes, and resolution of the type species, P. callianassae Kossmann, 1881. In our revision of Pseudione we erect a new genus, Robinione, and placed two species therein: R. overstreeti (Adkison & Heard, 1995) and R. brattstroemi (Stuardo, Vega & Cespedes, 1986). In addition, two other species are removed from Pseudione: P. compressa (Shiino, 1964) is moved to Ionella Bonnier, 1900, and P. panopei Pearse, 1947 is considered a synonym of Progebiophilus upogebiae (Hay, 1917). Bopyrid isopods represent a large, diverse taxon and our findings help clarify the taxonomy of those species found on ghost and mud shrimps.

Catinia aiso sp. n. was found in association with the mud shrimp, Axianassa australis Rodrigues & Shimizu, 1992 collected in the intertidal zone of Araçá Beach, state of São Paulo, Brazil (23°48’50’’S, 45°23’48’’W). The new species shares with Catinia plana Bocquet & Stock, 1957 the structure of the oral appendages, the setal formula of the swimming legs, the robust pedunculate sucker on the antenna, and the absence of the maxilliped in adult females. However, the two species can be separated by the rostrum shape, the presence or absence of an inner coxal seta on leg 4, and the structure of leg 5 in both sexes. Catinia aiso also differs from C. plana in the depressed ovoid body shape, the ornamentation of the maxilla in the female and in the modified claw of the maxilliped of the male. The sexual dimorphism expressed in the armature of the antennule and the endopodal segments of the swimming legs in C. plana, is absent in C. aiso. This is the first record of Catinia since the genus was established on the basis of material from the Baie de Morgat, France, in 1957.

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.

A New Species

The laomediid mud shrimp genus Axianassa Schmitt, 1924 is currently represented by 12 species worldwide. In this study, a new species of the genus, A. microlepis, is described and illustrated on the basis of two female specimens obtained from Awaji Island, eastern part of the Seto Inland Sea, Japan, at depth of 8 m. The type specimens were collected by means of an airlift suction sampler, which enables collection of infauna in subtidal soft sediments. The new species, representing the fourth species of the genus known from the western Pacific, is readily distinguished from other congeners by the unique structure of the antennal scaphocerite (short, non-dagger shaped, terminally rounded or having spine and blade), faintly crenulate rostral margins and the presence of a small lateral notch on the uropodal endopod. An amended identification key to the species of Axianassa and Heteroaxianassa Sakai, 2016 is provided.

A New Species

A new species of Espeleonaushonia is described from a single specimen collected in an underwater cave in Babeldaob Island, Republic of Palau. The new species is placed in Espeleonaushonia based on the following characters: exopod of third maxilliped well developed, propodus of first pereopod with spines on dorsal surface and along mesial and lateral margins; second pereopod not chelate with dactylus densely setose, fifth pereopod with simple dactylus, fourth to sixth abdominal pleura with serrate ventrodistal angle, and both rami of uropods completely divided. The description of this new species represents the first report of the genus from the tropical southwest Pacific.
