Introduction
Limnophora Robineau-Desvoidy is a large genus of Muscidae (Diptera). RobineauDesvoidy established the genus in 1830, with L. palustria as the type species. This genus has a worldwide distribution, according to recent data, there are approximately 230 species in the world, including 66 species and a subspecies in China. In recent years, many scholars collected Muscidae specimens from Hainan Island of China, including six new species and a new record species belong to genus Limnophora. Hainan Island belongs to Oriental regions, and located on the northwest of the South China (18°10′–20°9′N, 108°36′–112°2′E), it with a tropical moist monsoonal climate, and has many mountain ranges, valleys, streams and rivers, the various environments and special climate are fit for Limnophora species to live.
Materials and Methods
Specimens were collected from Hainan Island of China. They were examined using an Olympus SZ-ST stereomicroscope ( www.olympus.com): further details (dissection, drawing, etc.) were studied under an Motic SMZ-140 dissecting stereomicroscopes. Male and female genitalia were examined and illustrated after they were dissected from the fly's bodies, all illustrations were drawn on ink jet plotter paper. The genitalia of dissected specimens were mounted in glycerol in a plastic tube on the staging pin.
The morphological terminology follows that of McAlpine (1981). Absolute measurements were used for the body length in millimeters. Descriptions of a species are done in the following order: body length, head, thorax, wing, legs and abdomen. The type specimens of the new species and examined specimens described herein are deposited in IESNU and IZCAS.
