Remarks

• Systematics: Unaspis aesculi is related to U. euonymi, but differs in the stout and shorter pygidial dorsal ducts and in the shorter pygidial gland spines arranged singly. Resembles U. turpiniae Takahashi in the stout dorsal ducts, but is much different in the median lobes being distinctly larger than the 2nd and 3rd lobes, the shorter dorsal ducts and in the greater numbers of pygidial dorsal ducts and perivulvar pores (Takahashi, 1957b).
• Structure: Female scale pale brown, whitish at margin, much broadened posteriorly, thin, without median carina, about 1.1-1.2 mm long and 0.8 mm wide; exuviae pale yellowish brown. Male scale white, with median carina, about 1.1 mm long; exuviae pale yellowish brown. Adult female not sclerotized, broad, broadest at the basal abdominal segment, much narrowed anteriorly at maturity (Takahashi, 1957b).
• Biology: This species was collected at an altitude of 1000 meters (Takahashi, 1957b).
• General Remarks: Detailed description and illustration by Takahashi (1957b).
