A new sciaenid,Johnius (Johnius) laevis, is described from northern Australia and Papua New Guinea. Amongst theJohnius (Johnius) species with no mental barbel, ctenoid body scales, and more than 10 lower gill rakers, the new species is distinguished by the combination of the following characters: dorsal soft rays 29–34; scales above the lateral line 5–6, and below 8–10; eye diameter 22.4–30% HL; interorbital width 24.6–29.8% HL; and body scales with weakly developed ctenii.  相似文献

Two new species of the sciaenid genusNibea are described;N. squamosa from northern Australia and Papua New Guinea andN. microgenys from northern Australia. Both species differ from all known congeners in having a small, inferior mouth, with the lower jaw teeth uniform in size.N. squamosa is distinguished fromN. microgenys by a higher number of lateral line scales (57–60 vs. 48–50), the last pleural rib on the 11th vertebra (vs. 10th), and a longer and more slender caudal peduncle (length 25.9–30.4%SL, depth 6.3–7.9% SL vs. 21.5–26.3, 8.0–10.3).N. squamosa exhibits hyperostosis in some elements, such as the frontals and dorsal and anal pterygiophores.  相似文献

Synopsis Trichonotus halstead, family Trichonotidae, is described from 3 males and 4 females collected from a sand slope off the northwest end of Normanby Island, Papua New Guinea. It was part of a large population of 4 sympatric species of Trichonotus. The elaborately colored dorsal fin of the male, distinct among trichonotids, is brilliant gold anteriorly followed by a black patch, then a series of 8 to 40 conspicuous, black or dark brown spots that extend onto the upper caudal fin. The spines of the long dorsal fin are filamentous in the male and are numerous (VI to VIII, VII) in both sexes. This species lives in harems (1 male: 4 or 5 females) in well-defined territories and spends more than 80% of its day perched on sand. It feeds on benthic crustaceans and low drifting plankton. When disturbed, it dives into the sand where it also spends the night. It retires within 18 minutes after sunset and emerges within 11 minutes of sunrise. Mating takes place 6:00 h on the sand and the female then picks up the eggs into her mouth. There is evidence of gill-chamber brooding.  相似文献

I describe three new species of the diverse microhylid frog genus Oreophryne from Papua New Guinea. Two of these occur in two isolated mountain ranges along the northern coast of Papua New Guinea; the third is from Rossel Island in the very southeasternmost part of the country. All three are the first Oreophryne known from these areas to have a cartilaginous connection between the procoracoid and scapula, a feature usually seen in species far to the west or from the central cordillera of New Guinea. Each of the new species also differs from the many other Papuan Oreophryne in a variety of other morphological, color-pattern, and call features. Advertisement-call data for Oreophryne species from the north-coast region suggest that they represent only two of the several call types seen in regions further south, consistent with the relatively recent derivation of these northern regions as accreted island-arc systems. The distinctively different, whinnying, call type of the new species from Rossel Island occurs among other Oreophryne from southeastern Papua New Guinea but has been unreported elsewhere, raising the possibility that it may characterize a clade endemic to that region.  相似文献

A new species of crangonid shrimp, Philocheras wilkinsae (Decapoda, Crangonidae) is described from Hansa Bay, Madang Province, Papua New Guinea. The new species belongs to the japonicus group, and can be distinguished from the other members of this group by carapace dentition and carination. The pleopod structure is unique in the genus.  相似文献

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

A new species of seven‐gilled hagfish Eptatretus astrolabium (Myxinidae) is described from a 400 mm total length female trapped 1 km east from Planet Rock, Astrolabe Bay, Papua New Guinea, at c. 500 m depth. This is the first hagfish species reported from the waters around New Guinea. It can be distinguished from other hagfishes by a combination of characters including seven pairs of gill apertures, three‐cusp multicusps on the anterior and posterior rows of cusps, 10 posterior unicusps, 52 total cusps, 18–19 prebranchial pores, five branchial pores, 48–49 trunk pores, 83–84 total pores and no nasal‐sinus papillae.  相似文献

Parabrosmolus novaeguineae, a new genus and species of the subfamily Brosmophycinae (family Bythitidae) is described, based on a single specimen from Papua New Guinea. The genus is unique in the tribe Brosmophycini in having six branchiostegal rays and ten precaudal vertebrae, and is also similarly distinguished from two brosmophycine genera,Melodichthys andBeaglichthys, tribal allocations of the two latter being uncertain.Parabrosmolus also differs from all other genera in the subfamily by the following combination of characters: head scaly, anal fin origin slightly before midpoint of body, eye diameter shorter than snout length, three developed rakers on first gill arch and 16 (14+2) caudal fin rays.  相似文献

Summary Three new species of Carnoya Gilson, 1898 are described and illustrated from two species of rhinocricid millipedes from Papua New Guinea. C. fimbriata n.sp., C. perbella n.sp. and C. strobilina n.sp. are easily distinguished from the other described species of Carnoya by the exceptionally long tail. They are distinguished from one another by differences in spine configuration, head shape, vulval position and lateral ala shape in the females and by the presence or absence of a spine collar, the lateral ala shape and the copulatory papillae arrangement in the males. Scanning electron micrographs of the females of all three species are provided. ac]19840913  相似文献

Sampling in the framework of the research program called ‘La Planète Revisitée’ in Kavieng and Madang (Papua New Guinea) brought thus far unknown diversity of the brown algal genus Lobophora to the surface. DNA‐assisted alpha taxonomy allowed identifying the presence of 16 species Lobophora from these two localities, which only share four species in common. Ten species are newly described, including four, which are only known to the Bismarck Sea. A more exhaustive sampling across the Bismarck Sea, and more largely across the Coral Triangle, will very likely unveil an even greater diversity. The present study underscores the fragmentary nature of our knowledge of macroalgal diversity in this region.  相似文献

A new tiger beetles species, Polyrhanis dabraensis sp. nov., is described from Dabra (Foja mountains region, Papua, New Guinea, Indonesia). Its elytral markings are similar to those of Polyrhanis funerata and P. barbata, but it is much smaller and its anteapical spot is more expanded on the disc and is connected with the apical lunule. The aedeagus has a thin straight hook (spur) directed perpendicularly on the dorsal side, like that of P. io, P. innocentior, P. excisilabris, P. olthofi, and P. vannideki. It is easily recognized by its distinctive elytral markings and small body size.  相似文献
