Two new Sinogastromyzon (Balitoridae) described from Lixianjiang River, Yunnan Province, China.

Two new flat loach species of the genus Sinogastromyzon (family Balitoridae) are described in a recently published paper, viz.

      Sinogastromyzon lixianjiangensis Liu, Chen & Yang, 2009, sp. nov.

      Sinogastromyzon macrostoma Liu, Chen & Yang, 2009, sp. nov.

 Specimen of both new species have been collected during surveys commencing in 2003 in Lixianjiang River drainage, Yunnan Province, China. The benthis fishes live in swift current over gravel to stony substratum sintopic with Balitora kwangsiensis (Balitoridae), Glyptothorax quadriocellatus (Sisoridae), Garra orientalis (Cyprinidae), Hemibagrus pluriradtus (Bagridae), Poropuntius huangchieni (Cyprinidae), Pseudecheneis paviei (Sisoridae), Scaphiodonichthys acanthopterus (Cyprinidae), Schistura callichromus (Balitoridae), Schistura laterivittata(Balitoridae), Sinogastromyzon multiocellum (Balitoridae) (first record for China), Sinogastromyzon tonkinensis (Balitoridae), Vanmanensis tetraloba (Balitoridae). Remarkable is the absence of a gobiid in the listing. With these two newly described species the number of taxa placed in Sinogastromyzon should reach 21.

New Opsariichthys (Cyprinidae) described from southern Taiwan

A third Opsariichthys species, viz. Opsariichthys kaopingensis Chen & Wu, 2009, sp. nov., has been described from southern Taiwanese waters. The new species is a sibling species to in northern and western region of Taiwan occurring Opsariichthys pachycephalus Günther, 1868. Both species can be distinguished by morphometrics, meristics and specific coloration. The third Taiwanese Opsariichthys species populates riverine environments in the north of the island and in southern Zhejiang and Fujian Provinces, PR China.

New Garra (Cyprinidae: Labeoninae) described from upper Salween, Yunnan Province, China

The authors CHEN Ziming, ZHAO Sheng and YANG Junxing described a new species of the genus Garra, viz. Garra nujiangensis Chen & Yang, 2009 sp. nov. from Nanpenghe River, a secondary branch of the Nujiang River, upper Salween basin. The type series consist of 1 holotype + 9 paratypes. Two more juvenile specimens are registered as non-types as they show a characteristic trait; a pair of minute barbels in individuals smaller than 37 mm SL. Larger specimens do not possesses this character, hence, G. nujiangensis is regarded as beardless. The new species belongs in to the imberbis group. The original document is linked here.

New genus for Japanese-Korean minnows erected and new Candidia (Cyprinidae) described from Taiwan

The latest paper of CHEN, WU & HSU published in the Raffles Bulletin of Zoology Supplement No.19, 203-214 pp. features the outcome of intensive studies on the taxonomy and phylogeny of stripe minnows from Japan, Korea, China mainland and Taiwan. The authors conducted several mtDNA D-Loop sequences analysis on several stripes minnow species of the genera Parazacco, Candidia, Zacco, Opsariichthys. The result is rather interesting; there are two distinct monophyletic clades. Clade I is composed of Zacco platypus and Opsariichthys with the former in basal position. Clade II is composed of Parazacco spilurus, Candidia barbatus, Candidia pingtungensis sp. nov., “Zacco” sieboldii, “Zacco” koreanus and “Zacco” temminckii. This implies that the Japanese and Korean stripes minnows were formerly misplaced in Zacco. Hence, a new genus, viz. Nipponocypris gen. nov. with Leuciscus temminckii, Temminck & Schlegel, 1846 as the type species is erected. The following taxa are placed in the gen. nov.:

            Nipponocypris sieboldii (Temminck & Schlegel, 1846)

            Nipponocypris koreanus (Kim, Oh & Hosoya, 2005)

            Nipponocypris temminckii (Temminck & Schlegel, 1846)

In addition there is a new Candidia described from Fongkang River, Pingtung County, southern Taiwan. The sp. nov. named Candidia pingtungensis Chen, Wu & Hsu, 2008 is diagnosed and distinguished from its congener by meristics, morphometrics, color pattern and morphologic descriptive characters.

Two new species of Rhinogobius (Gobiidae) described from Fujian Province.

CHEN I-Shiung, National Taiwan Ocean University, and Peter J. MILLER (‘goby Miller’), University of Bristol, UK, described two new nondiadromous Rhingogobius from the Minjiang basin, Fujian Province, south China: 

            Rhinogobius rubrolineatus sp. nov. Chen & Miller, 2008

            Rhinogobius sagittus sp. nov. Chen & Miller, 2008

The initial description of these two landlocked, fluvial species was published in the Raffles Bulletin of Zoology Supplement No. 19, 225-232 pp. and additionally contains a diagnostic key to the species occurring in Fujian Province.

57 new species and two new genera of Cypriniformes and Siluriformes described from Vietnam

The Vietnamese ichthyologist Nguyen Van Hao from the Research Institute for Aquaculture No.1 in Hubac, Hanoi (RIAH) described in his already in 2005 published book ‘Ca Nuoc Ngot Viet Nam, Tap II [Freshwater Fishes of Vietnam. Vol.II]’ in total 57 species of Cypriniformes and Siluriformes new to science. The spp. nov. are belonging to the families Balitoridae (28 spp.), Botiidae (2 spp.), Cobitidae (3 spp.), Nemacheilidae (6 spp.), Amblycipitidae (1 sp.), Bagridae (9 spp.), Cranoglanididae (2 spp.) and Sisoridae (6 spp.). In addition to the enormous number of new species NGUYEN and coauthors erected two new genera:

            Parasewellia gen. nov. Nguyen & Nguyen, 2005

            Nahangbagrus gen. nov. Nguyen & Vo, 2005

Belonging to the Beaufortini the genus Parasewellia has been consequently placed into Balitoridae (Teleostei: Cypriniformes). The new genus Nahangbagrus have been placed into Amblycipitidae (Teleostei: Siluriformes). About the latter family is little known. It is a family of Asian torrent catfishes containing Amblyceps Blyth, 1858 (14 spp.), Liobagrus Hilgendorf, 1878 (13 spp.), Nahangbagrus gen. nov. Nguyen & Vo, 2005 (1 sp.) and Xiurenbagrus Chen & Lundberg, 1995 (2 spp. endemic to the Pearl River basin, SE China).

Liobagrus marginatus is a rather common amblycipitid catfish in south.

 

 

 

 

Here you can find an overview of all new taxa described in NGUYEN, 2005. Since the original descriptions contain misspellings and partly wrongly latinized specific epithets some taxa require first reviser action. However, the tremendous efforts necessary to compile a work like the present book must be greatly appreciated.

Hongshuia gen. nov. (Cyprinidae) including two new species of labeonine fishes described from Guangxi Province.

In Zootaxa 1682 (2008) a new genus including two new species of labeonine fishes from the Hongshui He, Pearl River basin, Guangxi province, SW China, are described. The new genus differs from all other Labeonini in a fully developed mandibular median lobe greatly protruded and ring-shaped acting as a sucking device in swift current environments. Summarizing there is a new genus and two species new to science described:

            Hongshuia gen. nov. Zhang, Qiang & Lan, 2008

            Hongshuia banmo sp. nov. Zhang, Qiang & Lan, 2008

            Hongshuia paoli sp. nov. Zhang, Qiang & Lan, 2008

The authors chosen H. paoli as the type species of Hongshuia. The type series of both spp. nov. are placed in the Institute of Hydrobiology (IHB), the Chinese Academy of Science, Wuhan, Hubei, China.

New Psilorhynchus (Psilorhynchidae) described from the Western Ghats, India.

ARUNACHALAM and MURALIDHARAN, 2008 described a a new species of the genus Psilorhynchus, which is the only genus in Psilorynchidae. The type series material of 6 specimen was collected from Korkanhalla River, a tributary of the Thunga River in Khudremukh National Park of Karnataka, Western Ghats, S India. This record is of importance since it was believed that Psilorynchus are occurring only in riverine environments in N/NE India. The new species, P. tenura sp. nov. Arunachalam & Muralidharan, 2008, is named after its comparatively slender peduncle region.

New blind cave dwelling loach of Protocobitis (Cobitidae) described from Guangxi Province

The genus Protocobitis (Cyriniformes: Cobitidae) containing P. typhlops only was erected in 1994 by YANG, CHEN & LAN by monotypy. The genus seems to be endemic to Guangxi Province, SW China, since the new species, P. polylepis sp. nov. Zhu, Lue, Yang & Zhang, 2008, was collected from a underground water source in the same province. The authors are basing their work published in Zoological Research, Aug. 29 (4), 2008 on two specimens collected 5 km away from the county town Wuming. The type series is placed in the Kunming Institute of Zoology (KIZ), the Chinese Academy of Sciences, Yunnan, China. As many cobitid loaches the new species shows sexual dimorphism (the holotype is a female, the paratype a male); the second and third pectoral rays are elongated and slightly thicker in males.
