6个不同鲤群体的形态差异分析

对黄河鲤、荷包红鲤、高背荷包红鲤、兴国红鲤、建鲤和黑龙江野鲤等6个鲤群体的12个形态比例性状进行单因素方差分析、主成分分析和聚类分析。单因素方差分析结果表明,除眼后头长/头长外,各鲤群体间在其他比例性状上出现较明显的差异。主成分分析构建了3个主成分,其贡献率分别为35.316%、23.221%、10.146%,累计贡献率为68.683%,并明显可将6个鲤群体划分为2个簇,荷包红鲤和高背荷包红鲤明显与其他群体区分开。聚类分析结果与主成分分析一致。在体高/体长、头长/体长、体厚/体长和尾柄高/尾柄长等4个比例性状上,有些群体的差异系数大于1.28,说明这些群体在这4个指标上的差异可达到亚种水平。结果表明,6个鲤群体在形态上存在一定差异和分化,主要体现在体型和头部特征上。     

Two new species of the genus <Emphasis Type="Italic">Cobitis</Emphasis> Linnaeus (Teleostei: Cobitidae) from southern China

Two new species of the genus Cobitis from southern China, C. hereromacula from the Luohe River in Guangdong Province and C. baishagensis from the Nandujiang River in Hainan Province, are described and illustrated here. C. hereromacula can be distinguished from its congeners by possessing the following combination of characteristics: absence of the second and third pigmentary zones of Gambetta; 13–16 oval blotches on the dorsum and 10–13 vertical, elongated triangular blotches below the midlateral line with more than 20 vertical dark brown bars between them; 6–7 narrow rows of dark spots on the caudal fin; a vertical oval spot smaller than the eye diameter on the upper part of the caudal peduncle; pointed mental lobes of the lower lip pointed with a slightly filiform tip; one slender and long needle-shaped lamina circularis at the base of the first branched ray of the male pectoral fins. C. baishagensis can be distinguished from its congeners by the fourth Gambetta zone being covered by 10–12 transverse elongated blotches; 4–5 narrow rows of dark spots on the caudal fin; a vertical blotch smaller than the eye diameter on the upper part of the caudal peduncle; males with a slender and long needle-shaped lamina circularis at the second branched pectoral fin ray in males; large scales with a slightly large focal zone; undeveloped mental lobes with a lower lip that does not end posteriorly in a filiform tip.     

SOME NEW SPECIES OF NANNOPLANKTON IN JIAOZHOU BAY, SHANDONG, CHINA

Three new spades and a new variety of nannoplankton, Chrysochromulina papillata, Gaysochromulina chiton var. minuta, Paraphysomonas simplexocorbita and Paraphysomonas bisorbulina are reported in this paper. All were isolated from the preliminary culture samples of seawater collected from Jiaozhou Bay, Shandong, China. The three species occurred at Station 1(120° 14.56′ E, 36°4′N) in November 1984, the new variety at Station 2 (120° 16.35° E,36°4.5′N) in January, 1985. The morphological features, especially the structures of the scales of these new nannoplankton,. are described. The differences between the new species and the related ones are discussed; their movement and nutrition, and the temperature and salinity of their biotopes are also mentioned.     

Morphology and phylogeny of Chrysogorgia pinniformis sp.nov.and C.varians sp.nov.,two golden corals from the Caroline seamounts in the tropical Western Pacific Ocean

Two new species of Chrysogorgia Duchassaing Michelotti,1864 collected from the Caroline seamounts in the tropical Western Pacific Ocean are described.Chrysogorgia pinniformis sp.nov.belongs to Versluys' group C(Squamosae typicae) with only scales in polyp body wall and tentacles.C.pinniformis sp.nov.is characterized by large branches pinnately branched and forming multiple fans with its small branches regularly and quasi-dichotomous branched,and scales and rods present in the polyp mouth area.It is most similar to C.pinnata Cairns,2007 by the pinnate trait,but differs from the latter by its group C pattern(vs.group A,Spiculosae) and having sclerites present in the polyp mouth area(vs.absent).Chrysogorgia varians sp.nov.belongs to the Chrysogorgia group A(Spiculosae) with rods distributed in the polyp body wall and tentacles.It is characterized by warty rods and elongated scales in the tentacles,many warts and ridges on the scales,conspicuously toothed margins at the rounded ends in the pinnules,and small rods with ridge-like warts in the polyp mouth area.This species was frequent and abundant in the Caroline seamounts during our cruises and its morphological variability in growth period was obvious.The phylogenetic analyses based on mtMutS and 28 S rDNA regions supported the assignment of the new species to the genus Chrysogorgia.However,the mtMutS marker showed very limited usefulness for species delimitation and inner relationship inference of Chrysogorgia.In contrast,the 28 S rDNA showed much higher level of genetic variation,and it may be a potential barcode for this genus.In the 28 S rDNA trees,the two new species clustered together.Additionally,compilation of our data showed that 42 of 78(ca.54%) Chrysogorgia species were found in the Indo-West Pacific convergent region,indicating that this area may be a hotspot of deep-water Chrysogorgia species.     

A new record of a flathead fish (Teleostei: Platycephalidae) from China based on morphological characters and DNA barcoding

A new record of Platycephalus sp.1 (sensu Nakabo, 2002) was documented based on morphological characters and DNA barcoding. We collected 174 specimens of the genus Platycephalus from Chinese coastal waters of Dongying, Qingdao, Zhoushan, and Beihai. Samples were identified as Platycephalus sp.1 morphologically. The coloration, meristic traits, and morphometric measurements are consistent with previously published records. In brief, it is an orange-brown flathead fish with dark brown spots scattered on head and body, lateral line scales 83 to 99 with one or two spine-bearing anteriormost pored scale, no yellow blotch on the caudal fin. Cytochrome oxidase I subunit (COI) gene fragments were sequenced for phylogenetic analysis. The mean evolutionary distance within the species Platycephalus sp.1 was 0.1%. Net evolutionary distances between Platycephalus sp.1 and other species of Platycephalus ranged from 10.8% to 19.7%, which is much greater than the threshold for species delimitation. The COI sequence analysis strongly supports the validity of Platyceohalus sp.1 at genetic level.
