Asterorhombus annulatus was long synonymized with A. intermedius. Twenty-nine specimens from the Coral Sea revealed that the former is clearly separable from the latter in having a short
first dorsal fin ray, slender gill rakers with spinules, distinctly shorter blind-side pelvic fin base, an absence of conspicuous
black spots on the ocular side of the body, greater eye diameter and greater interorbital width, and somewhat higher ranges
of upper jaw lengths. A. annulatus is redescribed as a valid species.

A new anthiine fish,Holanthias kingyo sp, nov., is described on the basis of two specimens (male and female) from the Ryukyu Is., Japan. The new species is most
similar toH. natalensis (Fowler, 1925), known only from South Africa, in having the following characters: dorsal fin soft rays 16 or 17, anal fin
soft rays 9, pored lateral line scales 46 or 47, scale rows above lateral line to origin of dorsal fin 9 1/2 or 10 1/2, and
gill rakers 10 or 11 +24 or 25=34–36. It differs from the latter in having more scales below the lateral line to the origin
of the anal fin (27 1/2 vs. 18–24), a U-shaped caudal fin with paddle-like lobes (vs. deeply forked caudal fin with each lobe
ending in a long slender filament), the outer margin of the soft anal fin vertical (vs. gently convex) and brown spots on
the body in female (vs. spots absent in females). 相似文献

The bembrid genusBembras Cuvier is reviewed. Five species,B. japonica Cuvier,B. adenensis Imamura & Knapp and three undescribed species, were assigned to the genus. Type species of the genus,Bembras japonica is redescribed on the basis of 36 specimens including the holotype, and three new species,B. macrolepis, B. longipinnis andB. megacephala, previously misidentified asB. japonicus, are also described on the basis of specimens collected from Australia and Indonesia.Bembras macrolepis differs from its congeners by having large body scales, a long pectoral fin with 17–19 rays and a dark blotch on slightly
upper portion to middle of margin, 14–15 anal-fin rays, small head and orbit, and caudal fin with a broad vertical dark band
near posterior margin.Bembras longipinnis is distinguished from other members of the genus by having a slightly long pectoral fin with 17–19 rays and lacking a small
black blotch near tip of upper rays, caudal fin with a large dark spot most intense in lower lobe, 1–2 gill rakers on upper
gill arch, 13–14 anal-fin rays, slightly elong ated head and small orbit.Bembras megacephala is characterized by the following combination of characters: caudal fin with several irregular narrow vertical dark bands,
small orbit, pectoral fin with 19–20 rays and lacking a small black blotch near tip of upper rays, head elongate, 2–4 gill
rakers on upper gill arch, 15 anal-fin rays and small body scales. A key separating the five species ofBembras is given. 相似文献

A new bembrid,Bembras adenensis, is described on the basis of specimens collected from the Gulf of Aden, western Indian Ocean. This species is easily distinguished
fromB. japonica, the only known congener of the genus, by the following combination of characters: larger orbital diameter, longer head length,
pectoral-fin with a small black blotch near tip of upper rays, 3 gill rakers on upper gill arch, 19 pectoral-fin rays, and
15 anal-fin rays (vs. smaller orbital diameter, shorter head length, pectoral-fin with several small spots forming irregular
bands, 2 gill rakers on upper gill arch, usually 17 pectoral-fin rays, and 14 anal-fin rays inB. japonica). 相似文献

A new serranid fish,Liopropoma dorsoluteum sp. nov., is described on the basis of two specimens from Yaeyama Is., Okinawa, Japan. The new species is most similar toL. erythaeum Randall & Taylor, 1988, in having the following characters: Dorsal fin rays VIII, 12; anal fin rays III, 9; pored lateral
line scales 52–53; anterior nostril situated midway between posterior nostril and anterior tip of snout; slightly forked caudal
fin with both lobes rounded. It differs from the latter species in having a shorter pectoral fin (23.4–23.8% SL vs. 26.9–29.0%
SL), greater preanus length (65.6–68.0% SL vs. 63.3–65.1% SL), fewer gill rakers (6+12 vs. 6–7+14–15) and yellow coloration
on the back (vs. light red on head and body) in fresh specimens. 相似文献

Gerres chrysops, a new gerreid species from the Gulf of Thailand, is described on the basis of 29 specimens, 58–83 mm in standard length
(SL). A small-sized species (less than 100 mm SL), it is characterized by a silvery-gold sheen on the head and trunk, vivid
yellow or yellowish-hyaline fins in life, two supraneural bones (formula 0/0/2/) and dorsal fin rays usually IX, 10. The new
species is similar toG. decacanthus (Bleeker, 1865) andG. setifer (Hamilton, 1822), which are redescribed. being similarly small valid gerreid species characterized by two supraneural bones.
Together, the three species comprise “theGerres setifer complex.”Gerres chrysops differs from bothG. decacanthus andG. setifer in life and fresh colors, the body being silvery-gold with vivid yellow or yellowish dorsal, caudal, anal and pelvic fins,
and yellowish-hyaline pectoral fins (vs. silver body with hyaline fins in the latter two species).Gerres setifer differs fromG. chrysops andG. decacanthus in having the last dorsal fin spine longer than the penultimate spine (vs. almost same length or shorter), usually ten dorsal
fin spines and nine soft dorsal rays (vs. usually IX, 10), and 8 or 9 lower series gill rakers (vs. usually 7).Gerres decacanthus differs fromG. chrysops andG. setifer in having a shorter head, lesser body depth at the first anal fin spine base, lesser body width at the pectoral fin base,
and shorter second dorsal and third anal fin spines. The new species is currently known only from Angsilla, near Bangsaen,
and around Si Chang Island, northeastern Gulf of Thailand.Gerres decacanthus inhabits southern Chinese waters andG. setifer is currently known from the Bay of Bengal to the Andaman Sea. 相似文献

A new species of blenny,Atrosalarias hosokawai is described on the basis of 15 specimens from the western Pacific. It is distinguished from the only known congeneric species,A. fuscus (=A. fuscus fuscus+A. fuscus holomelas), by the following: supraorbital cirrus broad and flat (vs. slender and thread-like inA. fuscus); dorsal fin broadly contacting caudal fin (vs. narrow contact); anal fin narrowly contacting caudal fin (vs. usually free
or (rarely) very narrow contact); posteriormost dorsal and anal fin rays long (vs. short); first or posteriormost soft dorsal
fin ray shortest (vs. posteriormost ray shortest); first soft anal fin ray shortest (vs. posteriormost ray shortest); caudal
fin rays branched in specimens over 36.0 mm SL (vs. unbranched); a large dark spot on base of pectoral fin absent (vs. present
or absent); a red margin on anterior dorsal fin absent (vs. present). Futhermore,A. hosokawai differs fromA. f. fuscus in having a lower number of dorsal fin spines (ten vs. eleven) and geographical distribution (western Pacific Ocean vs. Indian
Ocean and Red Sea). AlthoughA. hosokawai occurs sympatrically withA. f. holomelas, it can be further distinguished from the latter in lacking a large dark spot on base of pectoral fin. 相似文献

Two anthiine fishes from the eastern tropical Atlantic are described as newHolanthias cyprinoides andAnthias helenensis. The former is distinguished from the other Atlantic species ofHolanthias in having the forked caudal fin with rounded lobes and from the Indo-Pacific species in having no elongated dorsal spines or soft rays. The latter is closely related toAnthias asperilinguis Günther (South America, Atlantic coast), but differs from it in having more pectoral fin rays and more gill rakers. The present investigation onAnthias suggests that AtlanticAnthias is a genus distinct fromPseudanthias of the Indo-Pacific. 相似文献

Two new species of Kyphosus, K. pacificus and K. hawaiiensis, are described and the taxonomy reviewed of K. bigibbus Lacepède, 1801, closely related to the former. These three species are clearly distinguished from other species of Kyphosus in having 12 dorsal-fin soft rays, the anterior part of the dorsal-fin soft-rayed portion not elevated, 11 anal-fin soft rays, and 58–72 (usually more than 59) scales in longitudinal row along the middle body. Kyphosus pacificus is distributed in the Western-Central Pacific, being characterized by a pointed snout and 26–29 gill rakers (mode 27). Kyphosus hawaiiensis is distributed only in the Central Pacific and is characterized by a blunt snout, 23–25 gill rakers (mode 24), 18 pectoral fin soft rays, and the anterior part of the anal-fin soft-rayed portion well elevated. Kyphosus bigibbus is distributed antitropically in the Indo-West Pacific and is characterized by a blunt snout, 21–24 gill rakers (mode 22), 19 pectoral fin soft rays, and the anterior part of the anal-fin soft-rayed portion not elevated. In addition, Pimelepterus fallax Klunzinger, 1884 was found to be a junior synonym of K. bigibbus Lacepède. A lectotype and paralectotypes are designated for the former because the original type series included an example of a second species. 相似文献

Halichoeres bleekeri (Steindachner &; Döderlein, 1887), previously regarded as a junior synonym ofH. tenuispinis (Günther), is a valid species. It is distinct fromH. tenuispinis in nearly always having 13 instead of 14 pectoral rays. 11–15 instead of 7–11 suborbital pores, longer dorsal soft rays (1.95–2.3 in head length vs 2.25–2.4 fortenuispinis). and some features of color such as the absence of a dark spot at the upper base of the caudal fin of the female.H. tremebundus Jordan and Snyder, 1902 is a synonym ofH. bleekeri based on the female form, andArtisia festiva de Beaufort is a synonym ofH. tenuispinis, also described from the female phase,H. bleekeri is known from Korea and in Japan from Tokyo to the Izu Islands.H. tenuispinis is recorded from Hong Kong and Xiamen. China, and Taiwan. Records ofH. tenuispinis from the Philippines by Fowler and Bean (1928) represent misidentifications ofH. papilionaceus (Valenciennes). 相似文献

A taxonomic review ofXenotilapia sima andX. boulengeri (Cichlidae; Perciformes) from Lake Tanganyika
Two cichlid fishes from Lake Tanganyika,Xenotilapia sima Boulenger, 1899 andX. boulengeri (Poll, 1942) are often confused owing to insufficient information on the diagnostic morphological characters for each species.
Morphological and morphometric analyses showed thatX. sima differs fromX. boulengeri in having a greater number of teeth and anal and pectoral fin soft rays, thicker caudal peduncle, larger eyes, and a shorter
snout and anal fin base. 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
