Remarks

• Systematics: Slide-mounted adult female with: enlarged setae cylindrical, sides straight, apices round, 2 sizes of setae, larger setae on margin, smaller setae abundant over other part of dorsum, 3 or 4 lateral setae on margin of each abdominal segment, abdominal segment 8 with several setae anterior of anal ring (Matesova, 1967).Slide-mounted adult female with: enlarged setae cylindrical, sides concave basally, apices rounded, marginal setae slightly larger than other dorsal setae, 2 to 4 lateral setae on margin of each abdominal segment, with a few dorsomedial setae on abdominal segment 8 anterior of anal ring (Matesova, 1967). Based on a study of the type material of A. turanicus Matesova (1967), Kozár, et al. (2014) found that the distinguishing characters mentioned by Matesova (1967) for the species are highly variable and that its characters overlap with those of A. populi. Thus they synonymized the two species, with A. turanicus becoming becoming a junior synonym of A. populi. After studying the holotype of Acanthococcus turanicus, A. populi and A. salicis, Gavrilov-Zimin and Kurochkin (2019) disagreed with this synonymy, stating that they determined that A. turanicus was a junior synonym of A. salicis.
• Structure: Adult female wine red, almost black; felt-like test cream-white. (Kozár, et al., 2014)
• Biology: In bark crevices of trunk and thick branches. Often in large colonies. Female appears in egg sacs in the begining of May. Egg laying starts in the last days of June. (Matesova, 1967)
• General Remarks: Detailed description and illustration by Matesova (1967). Redescription and illustration in Kozár, et al. (2014) and Gavrilov-Zimin & Kurochkin (2019).
