Remarks

• Systematics: Ramakrishna (1936a) states "Cerococcus ramakrishnae sp. nov.(Green Ms.). This new species is related to C.ovicoides Cockl., from which it is distinguished mainly by its larger size. Specimens of this species were taken on rootlets of Ficus sp., at Coimbatore." Since this treatment includes a description (abbreviated as it may be), C. ramakrishnae must be considered an available name. It is clear that Ramakrishna did not realize that he was making the name available and describing it after himself. Lambdin apparently knew of the manuscript name of Green's but did not realize that the description by Ramakrishna (1936a) was valid and therefore described the species as new himself. When doing so, he corrected the spelling of the species epithet from "ramakrishnae" to "ramakrishnai" and moved the species from Cerococcus to Asterococcus. Lambdin also states that Asterococcus ramakrishnai is closely related to A. ovicoides.
• Structure: Body of adult female is pyriform (Lambdin, 1983). The following combination of character-states appear diagnostic: (i) anteroventral sclerotizations absent; (ii) five or six spinose setae present along inner margin of each anal lobe; (iii) dorsal fleshy setae on anal lobes rather spinose; (iv) tubular ducts on dorsum of one size only; (v) 8-shaped pores on dorsum all small and restricted to bands across abdominal segments IV, VI and VIII; (vi) cribriform plates absent; (vii) leg stubs absent; (viii) posterior stigmatic bands bifurcated; (ix) tubular ducts absent medially on venter of cephalothorax; (x) tubular ducts and 8-shaped pores on venter in a broad marginal band extending medially past each antenna; (xi) multilocular disc-pores unusually large (each about 8 μm wide), with a divided or double inner loculus; (xii) multilocular disc-pores present only on abdominal segments IV–VI; (xiii) stigmatic pore bands short, not reaching dorsum; (xiv) spiracular disc pores each with mainly 6–8 loculi; (xv) spiracular disc-pores forming a ring or band around spiracular atrium, and (xvi) antennae without a cone-like apex or setal cavity.
