A new species ofChimaera is described from three specimens collected from deep water fishing grounds off the North Island of New Zealand at depths
ranging from 327–1020 m. This species is distinguished from all other members of the genus by gray coloration with chocolate
brown reticulations and spots covering the body and fins, as well as additional external features such as rounded pelvic fins,
first dorsal fin with distinct white margin, preopercular and oral lateral line canals sharing a common branch, and morphology
of pelvic claspers in males bifid, the distal 1/3 divided, with pale colored fleshy, distal lobes. Comparisons are made toC. monstrosa andC. owstoni, the two most similar species in the genus. this represents the first species ofChimaera to be described from New Zealand. 相似文献

A new species of the genus Paracobitis, Paracobitis nanpanjiangensis is described from tributaries of the Nanpanjiang River drainage in China. It is distinguished from its congeners, except
P. oligolepis and P. wujiangensis, by body scaleless or with rudimentary scales (caudal peduncle with several deeply embedded scales). It can be differentiated
from P. wujiangensis by the complete lateral line (vs. incomplete), lower dorsal crest reaching the vertical of origin of anal fin (vs. shorter
and higher dorsal crest not reaching the base of anal fin). It is distinguished from P. oligolepis by the following characters: branched dorsal fin with 81/2 (a few 91/2) rays (vs. 91/2), interspaces between bars in front
of dorsal fin conspicuously thinner than those behind (vs. vermiform markings), dorsal head without vermiform markings or
obscure (vs. clearly vermiform markings on dorsal head), vertebrae 4 + 36–38 (vs. 4 + 39–41). 相似文献

A new zoarcid fish, Lycodes nishimuari, is described on the basis of four specimens from the Yamato Bank, the Sea of Japan, at depths of 642–669 m. Although this
species resembles Lycodes diapterus, L. hubbsi, L. pectoralis, L. macrochir, and L. nakamurae in having a deep notch in the pectoral fin and a single lateral line on the body, it is distinguished from them by the following
combination of characters: no scales on pectoral fin base; scales on dorsum before dorsal fin origin; suborbital, preopercular,
and last postorbital pores with risen rim; whitish lips; no whitish transverse bars on body; pectoral fin membrane and anterior
part of dorsal fin membrane without black spots; basal color of vertical fins black.

A new loach, Oreonectes elongatus sp. nov. is described based on collections from Mulun Township, Huanjiang County, Guangxi in China. It is distinguished from
its congeners by the combination of the following characters: most elongate body (body depth/SL 8.62–10.68%), blind, a forked
caudal fin, obvious adipose dorsal crest and ventral crest; entire body naked and de-pigmented. Although the new species has
a similar distribution with O. macrolepis, it can be distinguished by scales (absent in O. elongatus vs. present in O. macrolepis), shape of snout (elongate vs. round), the opposite position of the dorsal and pelvic fins origins (behind vs. front). The
new species shares the same possession of dorsal and ventral crests, a forked caudal fin, eyeless, naked body and incomplete
lateral line with O. translucens, but can be distinguished from the latter by caudal fin crest (more developed and translucent in O. translucens), longer anterior nostril tube and barbel, extreme of pectoral fin reaching 2/3 of the distance between origin of pectoral
and pelvic fins, more vertebrae (4 + 38–39 vs. 4 + 32). 相似文献

A new gobiid fish, Asterropteryx atripes, is described on the basis of eight specimens from Iriomote-jima Island, Ryukyu Islands, and El Nido, Philippines. It differs
from its congeners by having the following combination of characters: 3rd spine of first dorsal fin long, filamentous, distal
tip usually over end of 2nd dorsal fin base when appressed in both sexes; pelvic fins almost separated, innermost (=5th) segmented
rays connected by rudimentary low membrane between bases, and no frenum; 4–7 short spines on posterior margin of preopercle
(the uppermost spine usually just behind the cephalic sensory canal pore N); eye large, 32.3–35.8% of head length; enlarged
haemal arches on 1st two caudal vertebrae; a distinct black band from posterior margin of eye to caudal fin base (indistinct
in dark-phase individuals); black pelvic fin (vivid in dark-phase individuals); numerous minute bright blue spots on head
and body in life; no distinct dark spots on head and body; iris entirely reddish-brown or dusky (bright white ventrally in
pale-phase individuals) when alive or fresh, and entirely black in preservation, without white transverse bar on middorsal
surface; hovering habit. The new species appears to be most closely related with the other only known hovering species, A. striata; the latter is readily distinguished from the former in having no long, filamentous dorsal spine; semitranslucent pelvic
fin; and a series of small black spots along dorsal fin base and dorsal edge of caudal peduncle. Asterropteryx contains two distinct groups, and the monophyly of the genus is open to question.

The various life history strategies seen within the “yoshinobori” species complex of the genus Rhinogobius, which differentiated from an amphidromous ancestor, have been grouped ecologically into amphidromous, fluvial, and lacustrine types. In the Lake Biwa water system, two lacustrine forms exist, a newly discovered, exclusively lentic form and the already well known Rhinogobius sp. OR, which generally undergoes lake–river migration but also includes lentic individuals that share spawning grounds with the former lentic form. Detailed morphological comparisons and allozyme analysis revealed consistently clear differences between the two forms, indicating them to be distinct species. The newly discovered lentic form has many distinctive morphological features that enable it to be distinguished from sympatric Rhinogobius sp. OR: dwarfness, short snout, longitudinally slender pelvic fin, undeveloped frenum with a low lamella, low first dorsal fin in adult males, lesser caudal peduncle depth, scaleless predorsal and ventral areas, and incomplete sensory canals. The lentic form was temporarily named Rhinogobius sp. BW. The life history patterns of the lake-inhabiting populations were separated into two categories: a lake–river migratory lifestyle and an exclusively lentic lifestyle. 相似文献

Echinogobius hayashii, a new genus and species of Gobiidae is described, based on 11 specimens from Japan and Australia. This genus is distinguishable
from all other gobiid genera in having the following combination of characters: first spine of first dorsal fin hard and straight,
about 1.5 times second spine in thickness; first spine of second dorsal fin hard, with similar thickness as first soft ray
of second dorsal fin, supported by two normally-sized pterygiophores; snout convex; preopercular spine absent; predorsal scales
absent; all scales cycloid. The species occurs between 1–20 m in clear water on clear sandy bottoms influenced by fast tidal
currents. Based on our observations, it is not associated with an alpheid shrimp. 相似文献

Gerres methueni Regan, 1920, for many years identified asG. rappi (Barnard, 1927), is redescribed as a senior synonym of the latter species, following examination of two syntypes of the former
and comparative material from South Africa and Madagascar.Gerres methueni is characterized by prominent dark stripes along the scale rows above the lateral line and the 4 or 5 rows immediately below
it, 5–17 small scales on the preopercular flange, arranged in 1–3 scale row(s) at the corner, 42–44 pored lateral line scales+3–5
additional pored scales on the scaly sheath of the caudal fin base, 41/2–51/2 scales between the fifth dorsal fin spine base
and lateral line, and second dorsal fin spine length equal to or slightly shorter than the third dorsal fin spine length.Gerres methueni is currently known from South Africa, southern Mozambique and Madagascar, being endemic in those areas. 相似文献
