Remarks

• Systematics: Dactylaspis crotonis is similar to D. calcarata and D. lobata, but differs from both in the enlarged antennae and in the presence of distinct leg vestiges (Ferris, 1942). Zimmerman (1948) states that Kirkaldy (1904) may have misidentified Lepidosaphes tokionis as D. crotonis.
• Structure: Female scale elongate. Adult female about 1.75 mm long, body more or less fusiform and tending to be curved or distorted. Abdominal segments only slightly lobed laterally. Derm membranous throughout except for the pygidium (Ferris, 1942).
• Biology: Dactylaspis crotonis can occur in great abundance on the stems of its host. The females are covered in bark tissue making them difficult to distinguish (Ferris, 1942).
