Systematics: Rugaspidiotinus circumdatus most closely resembles Rugaspidiotinus fuscitatis from which it differs in having the ventral pygidial ducts markedly smaller than the dorsal ducts (Ferris, 1938a).
Structure: Female scale elongate and white. Male scale similar. Slide-mounted adult female 0.9 mm long, broadly oval, entire cephalothoracic region and a portion of the abdomen tending to be definitely sclerotized. Pygidium very weakly or not at all sclerotized, broadly rounded, its margin ruffled only by slight intersegmental notches; dorsally with numerous short, broad, definitely two-barred ducts, each of which has a narrow sclerotic rim about the mouth; ventrally with numerous ducts in a submarginal zone, these very noticeably smaller than the dorsal ducts and less clearly two-barred (Ferris, 1938a).
General Remarks: Detailed description and illustration by Ferris (1938a).
