Asterococcus schimae Borchsenius

Asterococcus schimae Borchsenius 1960: 120 –124.

Type details. CHINA, Yunnan, Chekang district, 1920m above sea level, on Schima wallichii , 17.v.1955. Depositories: ZIAS: 10/10 paratype adff—all other type specimens were deposited in China, including the holotype (I. Gavrilov, pers. comm.). For a discussion of the whereabouts of Borchsenius’ specimens, see under A.

querciola above. BMNH: labelled as for type series, 2/2adff; also 1/1adf but latter with no host listed (all probably part of type series).

Material studied. Paratype ff: CHINA, Yunnan, Chenkang vicinity, on Schima wallichii (Theaceae) , 17.v.1955, Hwang Tien-yung (BMNH): 2/2adff (g).

Comment. The main character-states diagnosing the adult female of A. schimae are: (i) anteroventral sclerotizations absent; (ii) anal lobes showing weak sclerotization throughout but with strong sclerotization on inner margins; (iii) four spinose setae present on inner margin of each anal lobe; (iv) multilocular disc-pores absent from ventral surface of anal lobes (Borchsenius’ figure suggests they might be present); (v) multilocular disc-pores present on abdominal segments II–VIII and on metathorax, with a complete band on segment VII; (vi) dorsum with two types of tubular ducts, a narrow duct sparsely on head and thorax and broader ducts present on dorsum of posterior abdominal segments; (vii) tubular ducts very sparse or even absent medially on venter; (viii) cribriform plates absent, (ix) leg stubs present, each with one or two small setae at base, and (x) transverse bands of dorsal 8- shaped pores present on abdominal segments III/IV and VII. The adult female of A. schimae would appear to be most similar to those of A. atratus and A. muratae .
