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).

A pictorial guide of the 176 commonest species of spiders from 20 families presented in full color is now published. – Pictorial Handbook of Hainan Spiders by Aimee Lynn A. Barrion-Dupo, Alberto T.
