This is the first study of caprellid amphipods from the coast of Papua New Guinea. Several collections from Madang Lagoon (north) and Bootless Bay (south) have been studied. Seven species in seven genera are recorded, of which Pseudoproto papua sp. nov. is described as new to science. The genus Pseudoproto Mayer, 1903 has consisted, so far, of only one species, Pseudoproto fallax Mayer, 1903. Although only a single male has been found of Pseudoproto papua sp. nov., differences in antennae, mouthparts, gnathopod 2 and pereopods 3 and 4 have revealed that it represents a new species of Pseudoproto. Lateral view figures of all species, together with a key to species level for the Caprellidea from Papua New Guinea are also included. Communicated by H.-D. Franke  相似文献

The genus Noculacia Mayer, 1903 is reviewed. Two new species, N. africana n. sp. and N. australiensis n. sp., are described based on material collected from southeast Africa and western-southern Australia, respectively. Noculacia bullata Mayer, 1903, the type species of the genus, is redescribed. Noculacia bogisa Mayer, 1903 is transferred to the genus Pseudoprotella Mayer, 1890 mainly on the basis of the presence of a well developed molar, the structure of pereopods 3 and 4, and the setal formula of the mandibular palp being 2-x-1. The genus Noculacia is presently composed of three species: N. africana n. sp., N. australiensis n. sp, and N. bullata Mayer, 1903. The genus Pseudoprotella is composed of P. bogisa (Mayer, 1903), P. inermis Chevreux, 1927, and P. phasma (Montagu, 1804).  相似文献

A new monotypic genus Cosmosycanus is established for Agriosphodrus perelegans Breddin, 1903. This genus is separable from Agriosphodrus Stål, 1867 by the head being much longer than the pronotum, and the posterior pronotal lobe lacking a median depression. The new genus is also distinguished from Sycanus Amyot and Serville, 1843 by the smooth posterior pronotal lobe and the unspined and non‐tuberculate scutellum. The type species, Cosmosycanus perelegans, comb. nov. is redescribed and considered the senior synonym of Sycanus elongatulus Distant, 1919.  相似文献

The taxonomic status of three rarely captured, nominal species of Indo-Pacific symphurine tonguefishes,Symphurus trifasciatus (Alcock, 1894),S. microrhynchus (Weber, 1913), andS. holothuriae Chabanaud, 1948, is resolved.Symphurus microrhynchus, previously known only from three specimens, is redescribed based on 12 specimens.Symphurus holothuriae, previously reported only from the holotype, is a junior subjective synonym ofS. microrhynchus. Symphurus trifasciatus is redescribed based on six specimens, including the lectotype designated in this study.Symphurus microrhynchus is distinguished from congeners by a combination of meristic features, head and opercle shape, dorsalfin position, and features of its pigmentation. The species occurs in relatively shallow tropical waters from Zanzibar through French Polynesia (the only reported occurrence of a shallow-waterSymphurus from a locality on the Pacific Plate), including Indonesia, Papua New Guinea, Vietnam, and northwestern Australia.Symphurus trifasciatus, known from deep waters along both coasts of the Indian subcontinent and adjacent waters, has an overall similarity in body shape and meristic features reminiscent of those inS. microrhynchus, but differs notably in having a longer and wider head, a distinctive opercle shape, number of scale rows on the head, and pigmentation pattern.  相似文献

The family Tropiduchidae is revised taxonomically comprising five genera and five species from Korea. Catullia vittata Matsumura is redescribed here on the basis of a series of males recently collected in Korea. Cixiopsis punctatus Matsumura and Catullia vittata Matsumura were transferred from Achilidae to Tropiduchidae and are redescribed here with male genitalia for the first time from Korea. Ommatissus binatatus Fieber previously reported was an incorrect identification of Ommatissus lofouensis Muir. Another species, Trypetimorpha koreana Kwon and Lee, is the macropterous form of Trypetimorpha japonica Ishihara. All Korean species of the Tropiduchidae are redescribed and illustrated, and an identification key to the genera of Tropiduchidae is provided.  相似文献

A study of both silicified and nonsilicified specimens of Permian reticularioid brachiopods from South China suggests thatPermophricodothyris, a genus previously rarely reported from China, is actually very common and abundant in the Middle and especially Upper Permian of South China. This study also clarifies, for the first time, that many of the reticularioid brachiopod species previously described asSquamularia in fact belong toPermophricodothyris. The new data presented in this paper also allows a critical evaluation ofPermophricodothyris in relation to its closest allies:Phricodothyris, Squamularia, Bullarina andNeophricodothyris. The revision reveals that a total of 18Permophricodothyris species are present in the Middle and Upper Permian of South China, with only one species,P. squamularioides, having survived the Permian-Triassic mass extinction. Two species,P. grandis (Chao) andP. guangxiensis Han, Zhou & Wang, are redescribed here, providing critical new information on the morphology and taxonomy of these species.  相似文献

Aega deshaysiana (Milne Edwards, 1840) and A. antillensis Schioedte & Meinert, 1879, have long been confounded, with all records eventually becoming regarded as belonging to one globally distributed species, namely A. deshaysiana. These two species are redescribed and differentiated, with A. schioedteana Bovallius, 1885 remaining in synonymy with A. deshaysiana. Aega deshaysiana occurs only in the eastern North Atlantic and Mediterranean, while A. antillensis is known only from the Caribbean and Gulf of Mexico. A further two named species are redescribed: A. excisa Richardson, 1910, previously placed in synonymy with A. deshaysiana, and A. magnifica (Dana, 1852). A neotype is designated for A. magnifica. This ‘complex’ or group of Aega species is distinguished from the others by their large eyes, which are usually medially united and occupy most of the head, their large adult size (20–60 mm), a posteriorly acute and defined pleotelson apex, and the uropod rami not extending posteriorly beyond the pleotelson, with exopod held at an oblique angle to the endopod and deeply notched endopod lateral margin. The group is not necessarily monophyletic, as there is a gradation in the depth of the uropod notch from deep to scarcely evident, and in eye size from entirely occupying the head to just separate (though the eyes are always large). Twelve new species in the group are described. All species are considered to be micropredators of fishes and elasmobranches, although prey records are few and unreliable owing to the readiness of these isopods to detach. Species of the group have been recorded from depths varying between 10 m and 600 m and occasionally deeper. Several have extensive distributions ranging from the Southern Ocean to tropical waters. The group is represented in all oceans. © 2004 The Linnean Society of London, Zoological Journal of the Linnean Society, 2004, 142 , 135–232.  相似文献

A new species, Pagastia hidakamontana sp. nov., is described from the alpine zone of the Hidaka Mountains in Hokkaido, Japan. Pagastia orthogonia Oliver, so far known only from the Nearctic Region, is newly recorded from Japan and redescribed. Females of P. lanceolata (Tokunaga) and P. nivis (Tokunaga) are redescribed, and the synonymy of P. lanceolata with Syndiamesa (Lasiodiamesa) crassipilosa Tokunaga (= Pseudodiamesa crassipilosa) is proposed. Keys to males and females of Japanese species of the genus are provided.  相似文献

The wobbegong genus Orectolobus occurring from Japan and its adjacent waters was reviewed, and O. japonicus was redescribed using ten specimens including a syntype. Only one species, O. japonicus, was regarded as valid among three species previously recorded from Japan. Orectolobus maculatus had been erroneously described from Japan because of the past nomenclatural confusion with O. japonicus. The specimen called “Karakusa-oose,” which had been identified with O. ornatus, was regarded as an irregular form of O. japonicus. Orectolobus japonicus was distinguished from the other congeners by having no tubercles on the body, five to eight dermal lobes in the preorbital group, two distally notched lobes in the postspiracular group, no dermal lobes on lower jaw, nasal barbel with a branch, no supraocular knob, relatively high dorsal fins with usually concave posterior margins, a lower number of precaudal vertebrae and intestinal valve turns, saddles on the back without black borders and yellowish and variously shaped blotches, not forming white O-shaped spots.  相似文献

Rhinochimaera pacifica is redescribed and a specimen from Tokyo Bay is designated as the neotype. A second species of the genus,R. africana, is newly recognized from Japan. A new scheme of measurements of the lateral line canals has been developed, and a comparison of proportional measurements of the snout width, eye length, and canal measurements clearly distinguishesR. pacifica andR. africana. Intraspecific variation ofR. pacifica and comparison ofR. pacifica andR. africana is discussed.Rhinochimaera pacifica has an irregular distribution in the north and south Pacific Ocean and Indian Ocean. This study also confirms a much wider range forR. africana than previously known and extends the range to the northern Pacific Ocean around the Japanese Archipelago.  相似文献

Summary Two species of Discocriconemella, one new and one previously described, were found in the Fiji Islands. D. caudaventer n.sp., from the rhizosphere of cocoa, Theobroma cacao L., is characterized by its reflexed tail and shape of the tail terminus. D. discolabia (Diab & Jenkins, 1966) de Grisse, 1967 is redescribed from the Fijian populations, the male for the first time.  相似文献

As a starting point for the revision of the genus Ctenolepisma Escherich 1905, the status of its type-species, Ctenolepisma lineata (Fabricius 1775), is clarified. In the present study, this species (originally described from Switzerland) is redescribed by means of many samples from several European countries and a neotype is designated. The constant presence of a third pair of abdominal styli in adult C. lineata s. str. leads to abandon the obsolete name C. lineata var. pilifera (Lucas 1840) for referring to a presumed non-typical variety of this species. The status of Lepisma pilifera Lucas 1840 is discussed, concluding that this name must be treated as a new synonym of Thermobia aegyptiaca (Lucas 1840). After our redefinition of the characters of C. lineata, an examination of many specimens of Ctenolepisma that were previously identified as C. lineata reveals that some of them are actually members of different taxa. This is the case for a species occurring in the Canary Islands, Northwest Africa, the Iberian Peninsula and the Balearic Islands. In this work this species is ascribed to Lepisma nicoletii Lucas 1846, which was described from Algeria and regarded as a synonym of Ctenolepisma lineata by Escherich; this species is now redescribed as Ctenolepisma nicoletii stat. res. This species differs from C. lineata in that it bears only two pairs of abdominal styli, and it also differs in the shape of the prosternum and femoral scales. Lepisma eatoni Ridley 1881, which was described from Morocco and the Canary Islands and subsequently regarded as synonym of C. lineata, is now synonymised with C. nicoletii.  相似文献

The systematics of the freshwater ostracods of the subfamily Dolerocypridinae in Southeast Asia is reviewed: A total of five species are known and they are assigned to three genera. Astenocypris papyracea (Sars) 1903 and Dolerocypris sinensis Sars, 1903 are redescribed. Dolerocypris fasciata (Müller) 1776, from Indonesia is figured and the hitherto observed variations are discussed. Dolerocypris pellucida Klie, 1932 is transferred to the genus Tanycypris Triebel, 1959.  相似文献

The liparid fish Liparis marmoratus is redescribed based on examination of two syntypes and two additional specimens. Liparis marmoratus is distinguished from other Sea of Okhotsk and Bering Sea Liparis by having a wide head, small mouth, short blunt snout, closely set chin pores, small gill opening, a firm body with slightly developed subcutaneous gelatinous tissue, a nearly horizontal dorsal body profile, and unique body markings and coloration. Liparis marmoratus was previously known only from the Sea of Okhotsk. A Liparis specimen collected near St. Lawrence Island in the northern Bering Sea was compared to the type series and determined to be L. marmoratus.
