Remarks
- Systematics: Thysanaspis perkinsi is close to T. litseae, from which it is distinguished mainly by the number of the enlarged marginal ducts on the pygidium of the 2nd-instar female: in T. perkinsi these ducts are present, in addition to the median one, only in one lateral pair, whereas in T. litseae in two lateral pairs (Takagi, 1969a).
- Structure: Pygidium triangular in outline, with 4 pairs of long setae and 6-8 slender ducts all around the apical margin, the marginal ducts being somewhat irregular in arrangement. 2nd instar female with 3 (1 median and 2 lateral) enlarged marginal ducts on the pygidium (Takagi, 1969a).
- General Remarks: Detailed description and illustration by Takagi (1969a).
