Pleurocope
iriomotensis
sp. n. and Prethura
tuberculata
sp. n. are described from Iriomote Island, Ryukyu Archipelago, southern Japan. These are the first records of Pleurocope from the Pacific and of Prethura from the Asian Pacific coast. Pleurocope
iriomotensis differs from its congeners in having lateral spine-like processes on pereonite 4 and coxal plates of pereonite 7. Prethura
tuberculata can be distinguished from its single congener in having a lateral short projection of protopod of pleopod 2. 相似文献

Atarbolana
makranensis
sp. n. is described from the intertidal zone of Makran along the Iranian coast of the Gulf of Oman. Atarbolana
makranensis
sp. n. can be recognized by the presence of a tuft of long setae on the antennal flagellum of males, elongate pleotelson with 12 robust marginal setae, pleotelson with narrowly rounded apex extending well beyond the uropodal endopod, uropodal endopod half as long as exopod with 14 robust marginal setae, and appendix masculina with an acute apex and extending beyond endopod distal margin. A key is provided for the four known species of Atarbolana Bruce & Javed, 1987. 相似文献

Nine species of terrestrial isopods are reported for the Polynesian island of Rapa Nui (Easter Island) based upon museum materials and recent collections from field sampling. Most of these animals are non-native species, but two are new to science: Styloniscus
manuvaka
sp. n. and Hawaiioscia
rapui
sp. n. Of these, the former is believed to be a Polynesian endemic as it has been recorded from Rapa Iti, Austral Islands, while the latter is identified as a Rapa Nui island endemic. Both of these new species are considered ‘disturbance relicts’ and appear restricted to the cave environment on Rapa Nui. A short key to all the oniscidean species presently recorded from Rapa Nui is provided. We also offered conservation and management recommendations for the two new isopod species. 相似文献

A new species of anisogammarid amphipod, Jesogammarus (Jesogammarus) ikiensis
sp. n., is described from freshwaters in the Iki Island, Nagasaki Prefecture, Japan, based on results of morphological and molecular analyses. The new species is distinguished from all members of the genus by the combination of small number of setae on dorsal margins of pleonites 1–3, short and small number of setae on posterior margins of peduncular articles of antennae, mandibular article 1 without setae, well developed posterior lobes of accessory lobes of coxal gills on gnathopod 2 and pereopods 3–5, and pectinate setae on palmar margin of female gnathopod 2. A key to all the species of Jesogammarus is provided. 相似文献

A new species of the genus Monoliropus belonging to the family Caprellidae was collected from the Yellow Sea, Korea. The new species differs from Monoliropus
agilis Mayer, 1903, Monoliropus
kazemii Momtazi & Sari, 2013, and Triprotella
amica Arimoto, 1970 as follows: 1) gnathopod 1 subrectangular; 2) pereonites 2–3 with acute triangular processes anterolaterally; 3) mandibular palp, apical article with four simple setae subdistally. The new species is fully illustrated and extensively compared with related species. This is the first record of the genus Monoliropus from Korean waters. A key to Monoliropus species is also given. 相似文献

A new species of Cumacea belonging to the genus Lamprops Sars was collected from the East Sea of Korea. This new species resembles Lamprops
comatus Zimmer, Lamprops
carinatus Hart, Lamprops
flavus Harada, Lamprops
pumilio Zimmer, Lamprops
tomalesi Gladfelter, and Lamprops
obfuscatus (Gladfelter) in lacking lateral oblique ridges on the carapace and lateral setae on the telson. The new species, however, is distinguished from its congeners by having a dorsal concave groove and a lateral rounded depressed area on pereonite 2. The new species is fully illustrated and compared with related species. A key to the world Lamprops species lacking lateral ridges on the carapace is also provided. 相似文献

Six species of terrestrial isopods from the province of Qazvin, central Iran, are recorded. Three species, Hemilepistus
klugii (Brandt, 1833), Protracheoniscus
ehsani Kashani, 2014 and Mongoloniscus
persicus Kashani, 2014, were previously reported from the province. Hemilepistus
elongatus Budde-Lund, 1885 and Protracheoniscus
major (Dollfus, 1903) are recorded for the first time, and one species, Protracheoniscus
sarii
sp. n., is described as new. The diagnostic characters of the new species are figured. 相似文献

Two new species of Anisomysis Hansen, 1910 (Mysida, Mysidae), Anisomysis (Anisomysis) spinaintus
sp. n. and Anisomysis (Anisomysis) phuketensis
sp. n., from coral-reef waters in Thailand are described. Anisomysis (Anisomysis) spinaintus, collected in the Chaolao Beach, Chanthaburi Province, is distinguished from the closely allied species Anisomysis (Anisomysis) incisa Tattersall, 1936, and Anisomysis (Anisomysis) hawaiiensis Murano, 1995, by the presence of 6–9 spines on the apical cleft of telson, which are absent in the latter two allied species. The new species can also be distinguished from Anisomysis (Anisomysis) aikawai Ii, 1964, by the presence of a deep telson cleft and a large number of spines on the lateral margin of telson. Anisomysis (Anisomysis) phuketensis
sp. n., collected in Ko Lon, Phuket, is distinguished from the allied species Anisomysis (Anisomysis) robustispina Panampunnayil, 1984, by having a short telson and a pair of long spines on the apical part of the telson. Keys to the subgenera and species of Anisomysis, including the two new species, are presented. 相似文献

The discovery of three new species of Enyalioides from the tropical Andes in Ecuador and northern Peru is reported. Enyalioides
altotambo
sp. n. occurs in northwestern Ecuador and differs from other species of Enyalioides in having dorsal scales that are both smooth and homogeneous in size, a brown iris, and in lacking enlarged, circular and keeled scales on the flanks. Enyalioides
anisolepis
sp. n. occurs on the Amazonian slopes of the Andes in southern Ecuador and northern Peru and can be distinguished from other species of Enyalioides by its scattered, projecting large scales on the dorsum, flanks, and hind limbs, as well as a well-developed vertebral crest, with the vertebrals on the neck at least three times higher than those between the hind limbs. Enyalioides
sophiarothschildae
sp. n. is from the Amazonian slopes of the Cordillera Central in northeastern Peru; it differs from other species of Enyalioides in having caudal scales that are relatively homogeneous in size on each caudal segment, a white gular region with a black medial patch and several turquoise scales in males, as well as immaculate white labials and chin. A molecular phylogenetic tree of 18 species of hoplocercines is presented, including the three species described in this paper and Enyalioides
cofanorum, as well as an updated identification key for species of Hoplocercinae. 相似文献

A new hermit crab species of the family Paguridae, Tomopaguropsis
ahkinpechensis
sp. n., is described from deep waters (780–827 m) of the Gulf of Mexico. This is the second species of Tomopaguropsis known from the western Atlantic, and the fifth worldwide. The new species is morphologically most similar to a species from Indonesia, Tomopaguropsis
crinita McLaughlin, 1997, the two having ocular peduncles that diminish in width distally, reduced corneas, dense cheliped setation, and males lacking paired pleopods 1. The calcified figs on the branchiostegite and anterodorsally on the posterior carapace, and the calcified first pleonal somite that is not fused to the last thoracic somite, are unusual paguroid characters. A discussion of the affinities and characters that define this new species is included, along with a key to all five species of Tomopaguropsis. 相似文献

Exosphaeroma
amplicauda (Stimpson, 1857) from the west coast of North America is reviewed and redescribed and revealed to be a group of closely related species. A neotype is designated and the species redescribed based on the neotype and topotypic specimens. Exosphaeroma
amplicauda is known only from the coast of California, at Marin, Sonoma and San Mateo Counties. Exosphaeroma
aphrodita (Boone, 1923), type locality La Jolla, California and previously considered nomen dubium is taken out of synonymy and re-validated. A further three species: Exosphaeroma
paydenae
sp. n., Exosphaeroma
russellhansoni
sp. n., and Exosphaeroma
pentcheffi
sp. n. are described herein. Sphaeroma
octonctum Richardson, 1899 is placed into junior synonymy with Exosphaeroma
amplicauda. A key to the Pacific West Coast Exosphaeroma is provided. 相似文献
