Antecerococcus ruber (Balachowsky, 1930) (Cerococcidae: Antecerococcus)

Nomenclatural History

• Cerococcus ruber Balachowsky 1930b: 203-206. Type data: TUNISIA: Bordj-bou-Hedma, on Rhantherium suaveolens, by M.C. Dumont. Holotype, female, by original designation Type depository: Paris: Museum National d'Histoire naturelle, France; accepted valid name Notes: There are 19 Slides containing 48 adult females and 1 slide with first instar larvae (Matile-Ferrero, personal communication, October 27th, 1999). Although Lambdin and Kosztarab (1977, p. 205) state that they studied paratypes, no holotype was designated by Balachowsky (Daniele Matile, pers. comm., April 2015) and, although the original description refers to "Type: in coll. St. ent. de Paris", it reports a range of adult female body lengths, implying that more than one specimen was measured, and describes the first-instar nymph. Thus, Hodgson & Williams (2016) consider all type specimens (adult and nymphs) in the NMHN to be syntypes and therefore have designated a lectotype.

Remarks

• Systematics: This species is close to Cerococcus cistarum (Hamon & Kosztarab, 1979).
• Structure: Adult female test is hemispherical or oval and red in color (Balachowsky, 1930d). Female is pear shaped with membranous derm (Lambdin & Kosztarab, 1977a). Adult females of A. ruber are unique in possessing the strange structure which occurs in the position of the cribriform plates in other Antecerococcus species. Initially, it was assumed that the tubules were the remains of parasitoid oviposition sites. The function of these tubules is unknown but is presumably similar to that of typical cribriform plates, which also is unknown. (Hodgson & Williams, 2016) The adult female of A. ruber has the following combination of character-states: (i) dorsum with two sizes of 8-shaped pores, each slightly different in size and shape; (ii) each 8-shaped pore with a large open pore between the lateral closed pores; (iii) largest pores present within apices of each stigmatic band; (iv) margins of posterior abdominal segments without large 8-shaped pores; (v) each group of cribriform plates replaced by four long internal tubules arising from a sclerotized area of derm on each side of abdominal segment IV; (vi) leg stubs present; (vii) posterior stigmatic pore band not bifurcated, but with a partial anterior branch; (viii) multilocular disc-pores in broad transverse bands across all abdominal segments, and unusually abundant on segment VIII; (ix) loculate pores with mainly 5-loculi in a band across metathorax; (x) quinquelocular disc-pores also present between each spiracle and associated leg stub; (xi) quinquelocular disc-pores also present associated with clypeolabral shield, and (xii) antennae without either a cone-like apex or a setal cavity. (Hodgson & Williams, 2016)
• General Remarks: Detailed description and illustration by Lambdin & Kosztarab (1977a). Hamon & Kosztarab (1979) provide a detailed description and illustration of the first instar. Detailed redescription and illustration in Hodgson & Williams, 2016.
