by original designation
accepted valid name
- General Remarks: Description and illustration in Takagi, 2003.
- Systematics: The adult female is diagnosed by the absence of differentiated marginal macroducts and the presence of segmental clusters of dorsal macroducts on the marginal to submarginal area of the pygidium. In these characters, Singapuraspis is similar to Rolaspis Hall. The new genus is distinguishable by the following combination of characters: the median trullae are not zygotic in spite of the presence of a sclerosis between them; the pygidial margin laterally to the median trulla is rugged, with a continuous series of conical or tubercular processes, among which the lateral trullae are not distinguishable in shape;. there are no gland spines on the pygidial margin, nor in the prepygidial region; and the dorsal surface of the pygidium is reticulate over a large central area. The pygidium is well defined on the dorsal surface by the intersegmental furrow between abd IV and V, and on the margin by the notch between them. (Takagi, 2003)
