Comment. This species does not fit into the genera Cerococcus, Cerochiton or Antecerococcus as defined here. In lacking both anteroventral sclerotizations on the anal lobes and large 8-shaped pores marginally on the dorsum of the posterior abdominal segments, it does not fall within Antecerococcus , whilst the fleshy setae on the dorsal surface of each anal lobe are quite long and fleshy and there is no line of three setose setae along the inner margins of each lobe, and so it appears not to belong to Cerococcus . It also lacks a lattice-like pattern of 8-shaped pores and the stigmatic pore bands typical of species of Cerochiton . Also, as it has abundant 8-shaped pores throughout the dorsum, it does does not fit into Asterococcus . On the other hand, it does have a (short and spinose) seta ventrally near the apex of each anal lobe (typical of Antecerococcus ). It also differs from all other known species of Cerococcidae in having a single, large cone-like spine in a deep cavity in each antenna and perhaps no other fleshy or setose antennal setae. It is also very unusual in having an incomplete posterior stigmatic pore band, with the spiracular disc-pores restricted to a group just anterior to each peritreme. Antecerococcus eremobius also has aborted stigmatic pore bands but the latter is otherwise a typical species of Antecerococcus .

Our observations differ from those of Lambdin and Kosztarab (1977) as follows: (i) the antennal spine is deeply embedded in a cavity in each antenna (in their key, Lambdin and Kosztarab state “antennae without slender and/or fleshy setae but with a median spinelike sclerotization” whilst in their description, they state “... with fleshy and slender setae” and do not mention the spine!); (ii) multilocular disc-pores are present on the metathorax, with four or five laterad to each leg stub and 11 medially (not found); (iii) the apex of each stigmatic pore band is divided by a transverse band of 8-shaped pores (not mentioned), and (iv) a few ventral 8-shaped pores are present near the mouthparts.

The adult female of C. indonesiensis is characterised by the following combination of character-states of Kosztarab and Lambdin in brackets: (i) 8-shaped pores on dorsum randomly distributed, not in a lattice-like pattern; (ii) 8-shaped pores on dorsum of three sizes, all quite small; (iii) larger pores restricted to near stigmatic pore bands; intermediate-sized and smallest pores abundant throughout rest of dorsum; (iv) cribriform plates in a submedial group of two on each side of abdominal segment IV; (v) tubular ducts on dorsum of one size only; (vi) multilocular disc-pores in bands across all abdominal segments and on metathorax; (vii) anterior stigmatic pore bands complete, posterior stigmatic pore bands each aborted, restricted to a small group of spiracular disc-pores just anterior to each peritreme; (viii) antennae with a large cone-like spine embedded in a cavity in each antenna; other setae possibly absent, and (ix) leg stubs present.
