Remarks
- Systematics: Rolaspis syrinx is closest to R. lounsburyi, but differs in having each gland spine on the pygidium accompanied by a small adventitious gland spine and also in the fewer dorsal ducts in the submedian group of the 6th segment (Williams, 1960c).
- Structure: Female scale white, slightly widened apically; exuviae pale brown, 2.0 mm long. Male scale white with smooth surface, uncarinated, 1.2 mm long. Adult female small, elongate, 1.0 mm long. Pygidium with a small anal ring situated towards base. 2 pairs of lobes; median lobes well developed, divergent, the space between forming a V, inner and outer edges serrated and the bases yoked together by a narrow sclerotized band; 2nd lobes bilobed, inner lobule longer than wide with a notch on either side, projecting a little more posteriorly than median lobes, outer lobule similar in shape to inner lobule but much smaller (Williams, 1960c).
- General Remarks: Detailed description and illustration by Williams (1960c).
