四川象尉属二新种(等翅目:尉科)

Two New Species of the Genus Nasutitermes (Isoptera:Termitidae: Nasutitermitinae) from Sichuan, China

最近,作者在整理四川省象尉亚科Nasutitermitinae标本时,发现象尉属Nasutitermes Dudley二新种,现记述如下。

In 1984-1985, a great number of termites were collected from Hejiang County, Sichuan Province. Among them two species of the genus Nasutitermes are new to science.1. Nasutitermes sinensis, sp. nov.(Fig. 1)The soldier of the new species comes very close to that of N. parvonasutus (Shiraki) in size, but the maximum head width lies behind middle and posterior margin slightly depressed in middle.Type locality: Hejiang County, Sichuan Province; soldiers (holotype, paratypes), workers, collected by Tian Maiming, Oct. 24, 1985, from dead stumps.2. Nasutitermes hejiangensis, sp. nov.(Fig. 2)The soldier of this new species comes close to that of N. moratus (Silvestri), but the head wider and pear-shaped, maximum width behind middle, and posterior margin slightly depressed in middle.It is also similar to that of N. guizhouensis Ping et Xu in the size of head, but its posterior margin slightly depressed in middle (vs. slightly rounded in middle), and dorsal profile almost straight (vs. concave).Type locality: Hejiang County, Sichuan Province; soldiers (holotype, paratypes), workers, collected by Tian Haiming, May 26, 1984, from a dead stump.AH the holotypes and some paratypes are preserved in the Shanghai Institute of Entomology, Some paratypes are preserved in Nanjing Institute of Termite Control.
