On April 6, 2013, the new Biodiversity Laboratory was declared opened by vice president of Hainan University, Professor Hu Xinwen and Kadoorie Charitable Foundation project manager, Mr Ronald Li in Hainan University. Preserved in the Laboratory are more than 20,000 arthropod specimens collected. There are about 2373 species and only 1578 have been identified. About 4,200 specimens in the Laboratory have been named and preserved. There are 32 holotype and 4 paratype specimens of new spider species discovered.
A five-day training workshop on the “Collection, preservation and photography of insects” was organized to acquaint students and staffs of Hainan University with techniques in arthropod preservation and documentations. Two MS students and 14 undergraduate students participated in the training. The training presented with a combination of lectures and hands-on exercises on arthropod preservation such as mounting using board spreader for moths and butterflies, pinning, card pointing, mounting on slides, and labeling, and the basics of photography. Various arthropod sampling methods were also introduced. This training workshop is the final activity of the Hainan Project on “Conserving Arthropod Biodiversity and Ecosystems Services in Rice Environments in Hainan, China”. The trained students will provide the resource base for the University to serve as laboratory assistants to maintain the Laboratory and its collection of insects and spiders and add to its collection new specimens from Hainan’s rich biodiversity. The Laboratory equipped with air conditioning, dehumidifier, microscopes, arthropod preservation and audio visual facilities will serve as the center of biodiversity research and education.

Spiders in rice ecosystems are frequently associated with predation. They are generalists and feed on most arthropod species in and around the rice ecosystem. There hundreds of spider species in the rice ecosystem. In our project we collected a total 400 species and 57 species were new to science. A paper discussing the spider diversity we collected have been published . The new species have been described and named and all the type specimens are now deposited in the “Biodiversity Laboratory” in Hainan University. Some were named in honor of Chinese scientists. Spider species richness is directly related to floral biodiversity especially on how the rice bunds are managed. High use of pesticides in and around rice production systems has a big impact on spider diversity.
We inventoried 400 species. These species belong to 166 genera comprising 29 spider families, namely, Amaurobiidae (1 species: 1 genus); Araneidae (66 spp. : 18 genera); Clubionidae (11 spp. : 3 genera); Corinnidae (5 spp. : 4 genera); Ctenidae (1 species : 1 genus); Gnaphosidae (2 spp. : 2 genera); Hahniidae (1 species : 1 genus); Hersiliidae (1 species : 1 genus); Linyphiidae (8 spp. : 6 genera); Lycosidae (19 spp.: 9 genera); Mimetidae (1 species : 1 genus); Ochyroceratidae (1 species : 1 genus); Oonopidae (1 species: 1 genus); Oxyopidae (9 spp. : 2 genera); Philodromidae (1 sp. : 1 genus); Pholcidae (18 spp.: 9 genera); Pisauridae (3 spp.: 3 genera); Psechridae (1 sp. : 1 genus); Salticidae (67 spp.: 34 genera) ; Scytodidae (1 sp.: 1 genus); Segestriidae (1 sp. : 1 genus; Sparassidae (8 spp.: 4 genera); Telemidae (4 spp.: 1 genus); Tetragnathidae (33 spp. : 8 genera); Theridiidae (80 spp. : 23 genera); Theridiosomatidae (2 spp.: 1 genus); Thomisidae (35 spp. : 22 genera); Uloboridae (7 spp.: 3 genera); and Zodariidae (7 spp.: 3 genera).
