贵州省螱类八新种(杆螱科、鼻螱科、螱科)

NEW SPECIES OF TERMITES FROM GUIZHOU PROVINCE, CHINA (ISOPTERA: STYLOTERMITIDAE, RHINOTERMITIDAE, TERMITIDAE)

贵州省等翅目的种类据蔡邦华、陈宁生1964“中国经济昆虫志——第八册”蔡邦华,黄复生1980“中国白蚁”前、后记录仅台湾土(尉虫)(黑翅土白蚁)一种。徐春贵、龚才、平正明1986“贵州的等翅目”专辑中记述为5科,14属,51种(其中30个新种)由此可见,贵州省等翅目的种类相当丰富,仅次于云南、广东、广西、四川诸省,是我国组成等翅目区系中的重要省份之一。

One of the author during 1985--1988 were collected a large number oftermites from Quizhou Province, in which 48 species were found after stu-dying, belonging to 9 genera and 4 families respectively. Among them 8species are described as new to science and diagnosed as follows: All type specimens are kept in Shanghai Institute of Entomology, Aca-demia Sinica. Paratype specimens are kept in Shanghai Institute of Ento-mology,Academia Sinica and The Science Institute. of House Administrationand Design of Quiyang separately. All measurements are in millimeters.1. Stylotermes mirabilis, sp. nov..
