Taxonomy notes on Vandeae(Orchidaceae)from China:Five new species and two new records

Five new species(Gastrochilus yei,Gastrochilus minimus,Luisia simaoensis,Taeniophyllum xizangense,Tuberolabium subulatum)and two newly recorded species(Cleisostoma tricornutum,Luisia inconspicua)of Vandeae(Orchidaceae)from China are described and illustrated.Gastrochilus yei is similar to G.affinis and G.nepalensis,but differs from them by having an epichile not lobed,the apex of the hypochile not bilobed,and a tine on the apex of the leaf.Gastrochilus minimus is similar to G.acinacifolius,but can be distinguished from the latter by having a flabellate epichile that is densely hirsute on the adaxial surface and an inconspicuous central cushion;in addition,the hypochile of G.minimus has a keel that extends to the apex of the epichile.Taeniophyllum xizangense is similar to T.stella and T.radiatum,but it is distinguished from them by having much bigger flowers,inflorescences densely covered with short-bristly hairs,papillae on the external surface of sepals,and bigger triangular-ovate viscidium.Luisia simaoensis is similar to L magniflora and L ramosii,but can be easily distinguished from them by having lateral sepals longer than dorsal sepals and petals,lip with irregular and waved margins,and lip with bilobed apex.Luisia inconspicua is moved from Gastrochilus to Luisia based on phylogenetic analyses of plastid matK sequence data.Tuberolabium subulatum is similar to T.camosum,but it can be easily distinguished from the latter by having an inflorescence much shorter than the leaves,yellow sepals and petals,and many small papillae outside the lip lobes.

Two new records of Pyramidellidae(Gastropoda,Heterobranchia)from China seas

This paper reports two species of the family Pyramidellidae (Gastropoda, Heterobranchia), Otopleura nitida (A. Adams, 1854) and Rugadentia manzakiana (Yokoyama, 1922).

Six Thallus Surface Types of Coralline Algae with Descriptions of Two New Records of Amphiroa beauvoisii and Neogoniolithon setchellii in Sanya reef,China

Coralline algae are globally distributed calcifying species and play critical ecological roles to marine ecosystems by contributing significantly to their structural complexity and diversity.Thallus surface types of historical samples in Sanya coral reef reserve were studied based on the scanning electron microscope(SEM)method.Our results show six thallus surface types within the study area:Corallina-type,Jania-type,Leptophytum-type,Phymatolithon-type,Pneophyllum-type,and Spongites-type.The Phymatolithon-type is the dominant surface type in Sanya reefs.Two new record species in the region are described:Amphiroa beauvoisii and Neogoniolithon setchellii.Although thallus surface types provide useful diagnostics characters for distinguishing coralline algae at tribe or subfamily level,species identification needs to refer to the reproductive features.This is the first surface study of coralline algae in the South China Sea.This result provides the baseline data needed for the monitoring and management of reef-building organisms of coral reef in China.

New Records for GASTROPODA Class of Species Found in the Rocky Intertidal Zone of the Marine Priority Region 32,Guerrero,Mexico

The GASTROPODA class, one of the best known marine environments, is formed by a large number of species and the shape of their shell structure varies greatly. These mollusks are distributed from the intertidal zone all the way to the abyssal zone, and there are also swimming and floating species. This research was conducted at seven sites, located in the Marina Priority Region 32 (MPR 32), located in the State of Guerrero, Mexico. The aim of this report is to document the scope of the geographic distribution of the 34 species of GASTROPODA class. 11,263 total specimens were analyzed. 108 species were identified, of which four species are new records for Mexico, 15 for the Transitional Mexican Pacific, 11 for the State of Guerrero and four for the MPR 32. Here we report a significant number of new records of species of class GASTROPODA found on the rocky intertidal zone of the MPR 32. The reporting of these new records, demonstrates the need to focus research efforts on the study of marine diversity, since knowledge in this respect is quite incomplete, especially regarding marine mollusks, a fact that has been reported by the National Commission for the Management and Use of Biodiversity.
