Asterococcus oblatus Xue & Zhang.  

Asterococcus oblatus Xue & Zhang 1990: 36–40   .

Astrococcus oblatus: Tang & Hao, 1995: 218   . Misspelling of genus name.

Type details. CHINA, Yunnan, Kunming, on Michelia fuscata   ( Magnoliaceae   ), -. vii. 1987 and -. iv. 1988. Depository: SAU, China: holotype adf (not confirmed).

Comment. No material of this species has been seen in this study but it is here assumed to be a good species of Asterococcus   . Based on Xue and Zhang’s (1990) illustration, it appears to be very similar to A. yunnanensis   and could be a synonym. However, based on Tang and Hao’s (1995) illustration of this species, A. oblatus   would appear to be close to A. schimae   although they do not illustrate the “trilocular” 8 -shaped pores in A. oblatus   which they use for separating these two species.

Based on the figure in Xue and Zhang (1990), the adult female of A. oblatus   is characterised by the following combination of character-states: (i) eight-shaped pores on dorsum of head and thorax very sparse; (ii) slightly larger 8 -shaped pores restricted to three or four transverse bands across about abdominal segments III, IV and VIII; (iii) cribriform plates absent; (iv) tubular ducts on dorsum of two sizes, broader ducts retricted to medially on about abdominal segments V and VI, narrower ducts throughout elsewhere but very sparse medially; (v) tubular ducts on venter sparse medially but abundant in a fairly broad marginal band; (vi) posterior stigmatic bands bifurcated; (vii) stigmatic bands each broad throughout their length, with many spiracular disc-pores; (viii) 8 -shaped pores on venter probably similar to larger pores on dorsum; (ix) multilocular disc-pores abundant across abdominal segments II –VIII, and also medially and submarginally on metathorax; (ix) leg stubs present; (x) loculate pores near antennae abundant, and (xi) with four setae along inner margins of each anal lobe.

Asterococcus ovoides (Cockerell)   . This species is here considered to be an Antecerococcus   species. See under Antecerococcus ovoides   above.
