Antecerococcus ovoides (Cockerell, 1901) (Cerococcidae: Antecerococcus)

Nomenclatural History

• Pollinia ovoides Cockerell 1901l: 225. Type data: SOUTH AFRICA: Durban, on unknown host, by Fuller. Lectotype, female, by subsequent designation (Lambdi1983,301). Type depository: Washington: United States National Entomological Collection, U.S. National Museum of Natural History, District of Columbia, USA; accepted valid name
• Cerococcus ovoides (Cockerell, 1901); Ferris 1918b: 332. change of combination Notes: Lambdin & Kosztarab (1977a) and Lambdin (1983) credit Green (1909a) as having moved P. ovoides Cockerell into the genus Cerococcus, but Green merely made the suggestion and Ferris (1918b) actually made the new combination.
• Cerococcus ovoïdes (Cockerell, 1901); Balachowsky 1932d: 34. misspelling of species epithet
• Asterococcus ovoides (Cockerell, 1901); Lambdin & Kosztarab 1977a: 1. change of combination
• Antecerococcus ovoides (Cockerell, 1901); Hodgson & Williams 2016: 92-94. change of combination

Remarks

• Systematics: This species was transferred to Asterococcus by Lambdin and Kosztarab (1977). The reasons for this are clear as A. ovoides has very few 8-shaped pores on the dorsum, but does have a transverse band of 8-shaped pores across about abdominal segment IV, two of the main characteristics that they used to diagnose Asterococcus. A. ovoides (character-states in Asterococcus in brackets): (i) has anteroventral sclerotizations (absent); (ii) has two long fleshy setae dorsally on each anal lobe (strongly spinose); (iii) lacks the line of spinose setae along the inner margin of each anal lobe (present); (iv) has a strong ventral seta near the apex of each anal lobe (absent); (v) has long stigmatic pore bands that appear to extend onto dorsum (Asterococcus species have short bands that do not appear to reach the dorsum); (vi) has non-bifurcated posterior stigmatic pore bands (always bifurcated in Asterococcus but non-bifurcated bands common in Afrotropical Antecerococcus species); (vii) has the inner margin of marginal band of 8-shaped pores and tubular ducts located a long way laterad of the antennae (on Asterococcus species, the antennae often lie within the band) and from the spiracles (generally much closer)—indeed, it is concluded that the marginal band on A. ovoides was almost certainly dorsal, (viii) has the spiracular disc-pores, in addition to forming the pore band, also forming a group just anterior to each spiracle but not forming a line or band around the atrium just laterad to each peritreme (in Asterococcus, they never form a distinct group anterior to each spiracle but form a semi-circle around the atrium laterad to the peritreme, with some disc-pores posterior to each peritreme), and (ix) has almost all loculate pores with five loculi (almost none with five loculi, almost all with seven ot eight loculi). On the basis of these observations, it is concluded that this species is not congeneric with the other Asterococcus species but is a fairly typical member of the genus Antecerococcus to which it is transferred.
• Structure: Adult female is pale brown with four longitudinal stripes of white secretion converging to the top of the scale. When soaked in potash, female turns a deep orange brown color. Male is yellowish or pink (Cockerell, 1901l). Female test is sacklike and globose, yellowish brown with the first instar exuviae positioned on middorsal area. A pair of white waxy bands is visible on each side extending from exuviae to base of test. Male test is elliptical and also yellowish brown in color, minute median carina composed of 5-6 series of waxy tubercles and with 5-6 corresponding transverse ridges (Lambdin, 1983). The adult female of A. ovoides can be diagnosed by the following combination of character-states: (i) anteroventral sclerotizations present; (ii) a pair of long fleshy setae present dorsally on each anal lobe; (iii) spinose setae absent from inner margins of anal lobes; (iv) strong ventral seta present near apex of each anal lobe; (v) dorsum with two or three sizes of 8-shaped pore, smallest restricted to very sparse medially; (vi) larger 8-shaped pores in a fairly broad marginal band along with a more dense band of tubular ducts; (vii) large 8-shaped pores absent from margins of posterior abdominal segments; (viii) stigmatic pore bands extending onto dorsum; (ix) cribriform pores in submedial groups of 1–3 on either side of abdominal segment IV, each deep and of an unusual structure; (x) tubular ducts on both dorsum and venter unusually narrow; (xi) leg stubs small; (xii) posterior stigmatic pore bands not bifurcated; (xiii) spiracular disc-pores in a group just anterior to each spiracle, not forming a band around spiracular atrium; (xiv) ventrally, inner margin of marginal band of 8-shaped pores and tubular ducts a long way laterad of antennae; (xv) almost all loculate pores with five loculi; (xvi) multilocular disc pores absent, replaced by submarginal groups of quinquelocular disc-pores on (probably) abdominal segments II and III, and (xvii) antennae without either a cone-like apex or setal cavity.
