New records of nine primnoid species are reported from the New England and Corner Rise Seamounts at depths of 1315–3855 m, making a total of 10 primnoid species known from this region. One new genus, Paranarella, and three new species are described: P. watlingi, Calyptrophora clinata, and Parastenella atlantica, the latter being the first record of Parastenella from the Atlantic. Calyptrophora pillsburyae is synonymized with C. microdentata, and the first subsequent report of Convexella jungerseni is noted. The fauna is hypothesized to have colonized the seamounts from the northward flowing Gulf Stream, the southerly flowing Deep Western Boundary Current, and/or via insular steeping stones from the east.
Nais inflataLiang 1963 is redescribed on the basis of fully mature specimens collected from several localities of the Yangtze River and Yellow River. The observations and redescription resulting from the study of mature specimens supports N. inflata as a valid species. This species is characterized by a thickened body, the ventral crotchets all of the same type with distal tooth usually longer than proximal one, a greater number of dorsal chaetae per bundle, stout dorsal needles with equal minute bifid teeth (<1 µm), presence of penial chaetae, and prostate glands on vasa deferentia instead of atria. The species is most closely related to N. communis Piguet, 1906 and N. variabilis Piguet, 1906. A table comparing allied species is provided.
The present work is the first published report of a benthic member of the Myodocopida off Puerto Rico. The collection contained a single specimen of an interesting new species, Diasterope puertoricensis (family Cylindroleberididae), which is described herein.
A new species, Amphiascoides coreanus, is described from the sandy beaches of Sangju-ri, Namhae, and Dolsan-do, Yeosu, the south coast of Korea. This species is clearly distinguishable from its congeners with the combined characters of the short bulbous caudal setae IV and V, three-segmented antennary exopod, and only one inner seta of the Leg 3 exopod segment 3. Additionally, the species is easily distinguishable from the congeners by the minute spinules on the dorsal body surface. The new species shares the three-segmented antennary exopod and only four setae on the third exopodal segment of Leg 3 with A. dispar and A. paradebilis but displays the characteristic shape of caudal setae. This is the first record of the genus Amphiascoides in the region.
The female and male of Enterocola fulgens van Beneden, 1860 are fully redescribed, based on specimens living in Polyclinum aurantium Milne Edwards collected at Roscoff. The female body is interpreted to be divided into cephalosome, 4-segmented metasome, and 6-segmented urosome. The cephalosome has paragnaths and the anus is displaced to the anterodorsal side of the anal segment. It is thought that these structures of the female represent diagnostic features for the genus. It is proposed that E. megalovaGotto, 1962 is synonymous with E. fulgens. The male of E. fulgens as studied in this paper closely resembles the males of two other known species of Enterocola.
A new species of crayfish, Procambarus (Austrocambarus) maya, is described from a salt marsh in the Sian Ka'an Nature Reserve, Quintana Roo, Mexico. The new species is most similar morphologically to Procambarus (A.) llamasiVillalobos, 1954, from which it can be distinguished by the absence of pubescence on the chelae; a gonopod with a large, mesially concave, blade-like mesial process, and a central projection and cephalic process basally fused. Other differences that separate the new species from P. llamasi are: the chelae are more slender, with the dactyli being longer than the palms; a pentagonal epistome, not heptagonal; a longer and more acute acumen; lateral spines of the rostrum and distolateral spine of the antennal scale more acute; antennal angle of the carapace with a well developed spine instead of a small projection; two spines on the pterygostomian angle of the carapace instead of three or four; and a narrower areola in which the suprabranchial grooves converge dorsally in less than half the length of the areola. The annulus ventralis of the new species is oval-shaped, the preannular plate has a straight anterior margin and is not completely covered laterally by the anterior sternal plates.
Furculanurida langdoni n. sp. is described from specimens collected in deciduous forest in Great Smoky Mountains National Park, Tennessee-North Carolina, U.S.A. It is distinguished from other Furculanurida species by the presence of five ocelli in each eyepatch, elliptical postantennal organ with 20–22 lobes, six mandibular teeth, and numerous sensillum-like setae on the fourth antennal segment All other known members of this genus have Caribbean, South American, African, or Himalayan distributions.
A new species of coelotin spider from forests of Busan city, South-eastern Korea, Ambanus cochlea sp. nov., is described with detailed illustrations, leg spination, trichobothrium patterns, and scanning electron micrographs. This species can be distinguished from other Ambanus spiders by embolus with large distal part, wound snail-like and embolus tip in male and genital opening situated in the middle of atrium, copulationary ducts oblique linear, spermathecal heads long cylindrical processes in female. A key to the species of genus Ambanus is provided.
Tarphonomus, a new genus of ovenbird (Aves: Passeriformes: Furnariidae) from South America, is described. Species included in the new genus, formerly placed in Upucerthia, are T. certhioides and T. harterti.
The twelve recognized species of nectar-feeding bats of the genus Lonchophylla occur in low- and middle-elevation, humid, Neotropical forests. Morphological and morphometrical analyses of specimens formerly lumped with Lonchophylla mordaxO. Thomas (1903) support recognition of Lonchophylla concavaGoldman (1914) as a separate species and reveal a third species from the western Pacific lowlands of Colombia and Ecuador that I describe herein as Lonchophylla fornicata. This new species is morphologically similar to Lonchophylla concava but is distinctively larger than that species. Tests for sexual dimorphism within these and other species of Lonchophyllini suggest a tendency for females to have slightly longer, narrower skulls, higher coronoid processes of the mandible, and longer forearms than males.
The genus Decaneuropsis of the Asteraceae, Vernonieae, subtribe Gymnantheminae, is named as new, with the transfer of 12 species from southeast Asia and Malaysia. Combinations are provided for the type species, Vernonia cumingiana, and 11 other known members of the genus, V. andamanica, V. andersonii, V. blanda, V. chingiana, V. craibiana, V. eberhardtii, V. garrettiana, V. gratiosa, V. obovata, V. philippinensis, and V. vagans.
