Remarks

• Systematics: Asterococcus oblatus is similar to A. schimae, but can be distinguished as follows: developed female tests are flat globose, top is concave; dorsal smaller 8-shaped pores are more numerous and spaced throughout cephalothorax and anterior abdominal segments; on the dorsal posterior abdominal segments the large 8-shaped pores are arranged in 2 transverse bands, the first band is 4-8 pores wide, with a wavy posterior margin, some small 8-shaped pores are scattered between them (Xue & Zhang, 1990).
• Structure: Based on the figure in Xue and Zhang (1990), the adult female of A. oblatus is characterized 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.
