  This species is placed in the genus Clavaspis MacGillivray on the basis of the robust clavate paraphyses, small anal opening, and basal sclerosis of L1, resembling that of Clavaspis ulmi (Johnson). The paraphyses are not as elaborately developed as those of most Clavaspis species, but they are more developed than some species that have recently been recognized as members of Clavaspis on the basis of molecular phylogenetics – C. perseae (Davidson) and C. patagonensis Schneider, Claps, Wei, Normark & Normark . Clavaspis virolae is similar to Clavaspis ulmi, but differs in having L2 present, plates fewer, dorsal macroducts fewer, medial paraphysis of first space less developed, and ventral macroduct orifices larger than those of dorsal macroducts. Clavaspis virolae also resembles species of Hemiberlesia Cockerell, especially H. ignobilis Ferris and H. ocellata Takagi & Yamamoto, but differs in having a smaller anal opening and fewer plates. It further differs from H. ignobilis in having L2 present and ventral macroduct orifices larger than those of dorsal macroducts, and from H. ocellata in having 2 pairs of conspicuous paraphyses present, L3 absent, and notching of L1 and L2 less deep. Yet another genus that C. virolae resembles is Diaspidiotus Berlese: the axes of L1 and L2 seem to converge slightly, causing the species to key out as Quadraspidiotus MacGillivray, now a synonym of Diaspidiotus, in Ferris’s (1942) key. But this is not as good a fit, as Diaspidiotus species lack basal scleroses of L1. It is also biogeographically less plausible, asDiaspidiotus is overwhelmingly a temperate Holarctic group. There exist Neotropical species assigned to Diaspidiotus, but these may be misplaced. The only such species reported from Panama, D. crescentiae Ferris, has a large anal opening and basal scleroses of L1, and is best regarded as Hemiberlesia crescentiae (Ferris), new combination.

• Structure: Adult female not pupillarial. Appearance in life not recorded. Slide-mounted adult female 475–900 μm long (holotype 860, median 565), 410–630 μm wide (holotype 620, median 460), broadest near mesothorax and metathorax. Body outline oval, nearly circular in smaller individuals (< 600 μm long), becoming elongate-oval in larger individuals. Derm membranous throughout at maturity except for pygidium. Antennae simple, each with one long seta. (Wei, et al., 2021)
