Remarks
- Systematics: Slide-mounted adult female with: enlarged setae gradually tapered to blunt or rounded apex except anal-lobe enlarged setae have acute apex; marginal enlarged setae conspicuously larger than other enlarged setae with 3 setae on margin of each abdominal segment (Tranfaglia & Esposito, 1985). Eriococcus cactearum has been considered a synonym of Eriococcus coccineus by Lindinger (1931a, 1936). Zimmerman (1948) thought it possibly to be a synonym of E. coccineus as did Ferris (1955a), and Hoy (1962). Tranfaglia & Esposito (1985) consider the species distinct.
- Structure: Adult female elongate-oval (Tranfaglia & Esposito, 1985). Antennae 7 segmented, each segment covered with a few, hair-like setae (except third segment without setae). Eyes situated on venter near margin. Anal lobes strongly developed, each with 3 enlarged setae with pointed apex. (Kozár, et al., 2013)
- General Remarks: Leonardi (1918) provides original description in Italian. Detailed description and illustration by Tranfaglia & Esposito (1985).
