Remarks

• Systematics: This species is close to C. deklei and C. parrotti (Hamon & Kosztarab, 1979). Cerococcus artemisiae males differ from other species in the Cerococcidae (character-states on two species of Antecerococcus in brackets): head: (i) poorly developed dorsal mid-cranial ridge (well developed); (ii) absence of ventral mid-cranial ridge (well developed); (iii) “interocular ridge” joining preocular ridge to postocular ridge present dorsad to dorsal simple eyes (ventral to simple eyes); (iv) presence of small pores on median crest (absent); (v) ocular sclerite with no setae laterad to ventral eyes (abundant laterad to vse), and (viii) preocular ridge well developed (poorly developed or absent). Abdomen: (i) some dorsal abdominal setae present on each segment (absent), and (ii) glandular pouch and glandular pouch setae absent (present). These differences suggest that C. artemisiae (from the New World) is significantly different from the two Antecerococcus species (from the Old World), C. artemisiae shares with A. indicus described below: (i) absence of reticulations on mesothorax; (ii) apparently only one tibial spur per leg, and (iii) absence of dorsospiracular setae (present on A. ornatus). (Hodgson, 2020)
• Structure: Female scale is suboval and is reddish ochreous with black specks. Male is subcylindrical and cream colored with black specks and this species is distinct due to "aborted antennae" (Cockerell, 1897w). The adult female of C. artemisiae is characterised by the following combination of character-states: (i) 8-shaped pores on dorsum not in a reticulate pattern but fairly randomly distributed; (ii) 8-shaped pores on dorsum of one or two sizes, both quite small; (iii) apex of each stigmatic pore band with one to three 8-shaped pores; (iv) cribriform plates fused into submedial groups of two–four on each side of abdominal segment IV; (v) tubular ducts of two sizes present, broadest medially on posterior abdominal segments, narrower ducts abundant elsewhere; (vi) multilocular disc-pores present in narrow bands 1-pore wide across abdominal segments II–VI and on metathorax; occasionally with one or two submarginally on VII; (vii) stigmatic pore bands bifurcated; (viii) stigmatic pore bands with few spiracular disc-pores, and (ix) small leg stubs perhaps sometimes present.
