ATROCOCCUS GOUX AND RELATED GENERA OF CHINA (HEMIPTERA:COCCOIDEA:PSEUDOCOCCIDAE)

WU San An( Department of Biology, Nankai University, Tianjin 300071)  
This paper lists 12 species of Chinese mealybugs belonging to the genus Allococcus Ezzat McConnell, Allotrionymus Takahashi, Atrococcus Goux, Chorizococcus McKenzie and Spilococcus Ferris. Among them two are new to science and one new to China. The type specimens are deposited in The Research Center of Scale Insects, Shanxi Agricultural University. Allococcus leppulus Wu, sp. nov. (Fig. 1) Adult female oval, 1.35 1.50?mm long and 0.82 0.95?mm wide. Antennae 8 segmented. Two pairs of ostioles. 2 or 3 pairs of cerarii, the cerarius on anal lobe with 2 conical seta, 3 or 4 hairs and 9 11 trilocular pores. Claw without denticle, hind coxa with some translucent pores. Circulus absent. Multilocular pores are mainly distributed on sternites 3 8. Oral collar tubular ducts of2 sizes, 18 25 of the larger ones and 2 4 of multilocular pores grouped lateral to fore coxa. Oral rim tubular ducts present mainly on dorsum and margin of venter. Holotype ♀ and paratypes 4♀♀ are collected from Xinlin Hot (43.9°N,116°E), Neimonggu on Leppula intermedia by LI Jie, July 8, 1986. The new species is similar to Allococcus ilu (Williams, 1970), but differs from the latter in having two or three pairs of cerarii and oral collar tubular ducts of two sizes (cf. only cerarius on anal lobe and tubular ducts of one size). Allotrionymus shanxiensis Wu,sp. nov. (Fig. 2) Adult female elongate oval, 2.6 3.1?mm long and 1.1 1.3?mm wide. Antennae 7 segmented with the 3rd shortest. Only anal lobe cerarius presents, with 2 long spines, 2 or 3 hairs and 4 or 5 trilocular pores. Circulus small and circular, located between sternites 3 and 4. Claw without denticle, hind coxa expanded, with a group of ductlike translucent pores. Multilocular pores mainly are distributed on sternites 4 8. Two sizes of oral collar tubular ducts. Oral rim tubular ducts present or dorsum, about 23 in number. Holotype ♀ and paratypes 3♀♀, collected from Taigu County (37.4°N,112.5°E), Shanxi Province under leaf sheath of Medica scabrosa,July 12, 1995,by author; paratypes 12♀♀, June 16, 1995, other data same as holotype. This species closes to Allotrionymus rostellum (Lobdell, 1930), but oral collar tubular ducts of two sizes in the former, of one size in the latter. Atrococcus cracens Williams New record to China. Distribution. China: Shanxi (Huiyuan), Neimenggu (Xi Ujimqin Qi); England; Hungary; Latvia; Poland; Russia Sahalin Island; Sweden; Wales. Host plant. Artemisia spp., Heterropappus altaicus .
