Antecerococcus badius (Leonardi) , comb. nov.

Cerococcus badius Leonardi 1911: 9 –11.

Type details. ARGENTINA , Cacheuta (Mendoza), on Baccharis rosmarinifolia , 17.iii.1909, Leonardi. Depositories: USNM: lectotype adf (designated by Lambdin & Kosztarab 1977: 71) on a slide with 2 paralectotype adff, + 5/9 paralectotype adff and 1/3 first-instar nymphs. BMNH: 1/2 paralectotype adff. BME: 2/4 paralectotype adff.

Material studied. Paralectotype: ARGENTINA , Cachueta , on Baccharis rosmarinifolia (spelt rosmatinifolia) ( Asteraceae ), 17.iii.1909, Leonardi (BMNH): 1/2adff (one f, other g but twisted). Also: BRAZIL, Porto Alegre, on B. dracunculifolia , -. iv.1963, F.D. Bennett (BMNH): 1/1adf (g); São Paulo, Santa Amaro, on Baccharis sp., no date, Julius Melzer per Dr. Horn (BMNH): 1/4adff (f–g).

Comment. This species is not illustrated here but is figured by Lambdin & Kosztarab (1977, plate 10). They considered that there were three sizes of 8-shaped pores forming the swirled pattern on the dorsum, but here it is considered that there were only two sizes, with the pores variable in size, and with the smallest in the centre of each swirl and the largest outside. Lambdin and Kosztarab also show a band of larger 8-shaped pores on the venter across either abdominal segment IV or V and state that those on three or four of these abdominal segments are larger. Here it is considered that all ventral 8-shaped pores are about the same size. Also, no fine setae were found here on the inner margins of the anal lobes.

The main character-states diagnosing the adult female of A. badius are: (i) dorsum with three or four sizes of 8- shaped pores; (ii) large 8-shaped pores on dorsum in swirls; (iii) large 8-shaped pores not forming a line along margins of posterior abdominal segments but in a transverse band anterior to anal plate; (iv) smallest 8-shaped pores present laterad to apex of each stigmatic pore band; (v) cribriform plates in 5–7 submedial clusters on each side of thoracic and anterior abdominal segments, each cluster with 3–8 plates; (vi) each cribriform plate small but with large micropores; (vii) leg stubs present; (viii) posterior stigmatic pore band bifurcated; (ix) multilocular discpores absent, and (x) all stigmatic pore bands broad.

The adult female of A. badius falls within Group D in the key to species of Antecerococcus and keys out close to A. baccharidis and A. zapotlanus . All three are from Central and South America.
