Antecerococcus citri (Lambdin)   , comb. nov.

Cerococcus citri Lambdin 1986: 369–371   .

Type details. CHINA, Quarantine material at Mt. Shasta, Shasta Co,, California, Jiangsu, Taichow (Taizhou), on chinese unshiu   orange ( Citrus unshiu   - Rutaceae   ), 17.xii. 1982, C. Silva. Depositories: IEBC, China: Holotype adf (not checked). Note that Lambdin (1986) states that he deposited the following in USNM but they are not there (Miller, pers. comm.): CHINA, Taichow (Taizhou), on Citrus   sp., -. v. 1935, F.G. Chen: 2 / 5 paratype adff.

Comment. No material of this species has been seen during this study. However, it is clear from Lambdin’s (1986) description and illustration that this is an Antecerococcus   species as it has the following combination of character-states: (i) pairs of long fleshy setae on dorsum of each anal lobe; (ii) large 8 -shaped pores in a band of 8– 14 pores along margin of posterior abdominal segments; (iii) each anal lobe has a setose seta on ventral surface near apex; and (iv) strong setose setae absent along inner margins of each anal lobe. According to Lambdin (1986), the adult female is characterised also by: (i) presence of large 8 -shaped pores in swirls throughout dorsum anterior to cribriform plates; (ii) five sizes of 8 -shaped pores on dorsum; (iii) smallest 8 -shaped pores present in apices of each stigmatic band; (iv) cribriform plates in a submedial group of 2–4 plates on each side of abdominal segment IV; (v) leg stubs present; (vi) posterior stigmatic pore bands bifurcated; (vii) multilocular disc-pores present in bands across all abdominal segments and laterad to each metathoracic leg-stub; (viii) stigmatic pore bands narrow, with few spiracular disc-pores; and (ix) largest 8 -shaped pores appearing to extend onto venter.

The adult female of A. citri   falls within Group D in the key to species of Antecerococcus   , and keys out close to the Afrotropical species A. oumeensis   and A. thesii   .
