Descriptions of two new record species of Scutellonema (Nematoda:Tylenchida) from China

From 2011 to 2012, we collected Scutellonema commune from the rhizosphere soil of coconut （cocos nucifera L.） and Scutellonema magniphasma from the rhizosphere soil of Rosa chinensis in Shenyang, China. S. commune was characterized by rounded scutella, which was varied from two annules anterior to the anus and five annules posterior. The lateral field was not areolated at the level of scutella. S. magniphasma was characterized by varying scutellum, about 7.0 μm in diameter, in position from four annules posterior to four annules anterior to the anus, and areolated at the level of the scutellum.

A new record of Dasyatid fish in China: Dasyatis laosensis

One specimen was collected from the main course of Lancangjiang River （upper reach of Mekong） in Guanlei Port, Xishuangbanna, Yunnan, China in April, 2008. It is identified as Dasyatis laosensis, a new record of Dasyatidae species in China. It could be distinguished from other Dasyatis species by a combination of the following characteristics： one enlarged venomous spine on the tail, ventral surface of body with orange marginal coloration, tail length greater than body length.

One specimen was collected from Lancangjiang River in Jinghong,China on August 1st,2006.It is identified as Anguilla bicolor McClelland,1844,a new record of Anguillidae species occurring in Lancangjiang River in China.It could be distinguished from other Anguilla species by the character as：dorsal-fin origin located above vent vertically.It is an active nocturnal forager,feeding largely on a diet of crustaceans and mollusks.

A New Fish Record in the Yangtze Estuary:Slender Mandarinfish Siniperca roulei

A new recorded fish （Siniperca roulei） of the Yangtze estuary and Shanghai district was collected at the west end of Chongming Island in the survey on the intertidal fishes in May, 2008. It belongs to Family Serranidae of Order Perciformes. Its main features were described as the following： body slim and long, nearly tubby; head long and a little fiat, and proboscis sharp; oral fissure big, the mandible apparent protruding, and the upper jaw outstretch to the area under the eye; ten thin sawteeth and two declining spurs at the rear edge and the ventrolateral edge of the front operculum, respectively; one fiat spine at the back-end of the operculum with one short spine at its up-end; body tawny and some anomalistic macula and dark spots on the head and both sides of the body. Owing to the overfishing and water pollution, the resource amount of the fish has decreased sharply in recent decades. It has been listed in China Red Book of Endangered Animals. Currently, very few studies on this fish species have been carried out, especially those on their breeding, feeding and growing characteristics are even scare. Hence, it is extremely urgent to carry out the study and conservation on this species.

Pectinatella magnifica (Leidy,1851)(Bryozoa,Phylactolaemata),a biofouling bryozoan recently introduced to China

Freshwater biofouling threatens a variety of human activities,from the supply of water and energy to recreation.Several species of freshwater bryozoans are notorious for clogging pipes and filters but have been relatively poorly studied to date.We report,for the first time,a biofouling species of freshwater bryozoan,Pectinatella magnifica(Leidy,1851),from several freshwater rivers,lakes and ponds in China.A complete description,national distribution and the fouling problems are provided.Exactly how Pectinatella magnifica arrived in China remains unclear,but anthropochory and zoochory are considered to be important dispersal pathways.
