【Abstract】 This paper deals with 7 Chiense species of the genus Crisicoccus . Two species new to science were described and illustrated. A new combination was established. The type specimens are deposited in the Research Center of Scale Insects, Shanxi Agricultural University. Crisicoccus helanensis sp. nov.(Fig. 1) Adult female pear shaped. On slide, about 2.25mm long and 1.4mm wide. Antennae 8 segmented. Cerarii of 6 or 7 pairs, present on the last 6 or 7 abdominal segments. Anal lobe cerarii with 2 large conical setae, 5～7 hairs and a group of trilocular pores. Legs normally developed, hind coxa without translucent pore and claws without a tooth on planter surface. Circulus absent. Anal lobes have a broad sclerotized bar on its ventral surface. Multilocular poresmainly present on abdominal sternites, a few close to coxae of legs. Oral collar tubular ducts of 3 sizes. And hairs at different length on body surfaces. Holotype ♀ is collected from Mount Helan [38.8°N, 105.9°E], Inner Mongolia, on Senecio atractylidifolius (Compositae) by Li Jie on July 7, 1991. Paratypes: 4♀♀, the same data as holotype; 5♀♀, collected from Mount Helan[38.5°N, 106.1°E], Ningxia Hui Autonomous Region, on an unknown plant by Wang Jianyi on July 7, 1990; 3 ♀♀, from Qinshui County [35.6°N,112.1°E], Shanxi Province, on Bothriospermum chinense by author on July 13, 1995. This new species is similar to C.pini (Kuwana), but can be distinguished by numerous multilocular pores, which distribute on all abdominal sternites, the presence of oral collar ducts on dorsum, and by hind coxae without translucent pores. Crisicoccus punicus sp.nov.(Fig.2) Adult female oval, about 1.3mm long and 0.75mm wide. Antennae with 8 segments. Ostioles developed, with spinules and disc pores on its lips. 6 or 7 pairs of cerarii present on last 6 or 7 abdominal segments. Anal lobe cerarii with 2 thick conical seta, 2 or 3 hairs and 7～9 trilocular pores; C 17 ～C 14 with 2 slender seta and 2～4 disc pores. Anal lobes with ventral, narrow sclerotized bar. Circulus oval, located between abdominal sternites 3 and 4. Multiolocular pores only distribute on sternite 4～8. Oral collar tubular ducts of two sizes. Spinules occur on dorsum and margin of ventral surface, the other part with slender setae. Holotype ♀ and paratypes 3♀♀, collected from Baotou City [40.6°N, 109.8°E], Inner Mongolia, on Punica granatum by Li Jie on July 22, 1983. This new species closes to C.moricola Tang, but hind coxae without thanslucent pores in the former, with numerous translucent pores in the latter. Besides, they differ in the distribution of oral collar tubular ducts. Crisicoccus wistariae (Green) comb.nov. Transferred from the genus Dysimcoccus .更多还原
