Remarks
- Systematics: Subfamily DIASPIDINAE Tribe DIASPIDINI Subtribe FIORINIINA (Normark, et al., 2019)
Keralaspis has no close relatives among the known genera. Balaspis might be a possible relative based on a description of the trullae, the dorsal macroducts uniform in size, and the marginal macroducts not well differentiated from the submarginal macroducts. It differs from Keralaspis in the median trullae small and conical and entirely produced beyond the pygidial margin, the second trullae also small and the third trullae nearly obsolete. Keralaspis differs from other genera of the Diaspidina in all the dorsal macroducts of the pygidium uniform in size, in the submarginal macroducts arranged in segmental and infrasegmental rows, and in having no marginal macroduct between the median trullae. (Takagi, 2007a)
- Structure: Adult female: Body elongate, but stout; pygidium broadly rounded marginally. This genus has bilobate lateral trullae and gland spines, and thus it belongs to the subfamily Diaspidinae. A pair of well-developed gland spines present between the tullae, located on the ninth abdominal segment and their presence is a primitive character.
The second instar male of the type species is homomorphic in the structure around the pygidial apex, but possesses dorsal ducts of a modified type and forms an amorphous test fluffy with wax filaments, supporting the view that the genus belongs to the Diaspidini.
- General Remarks: Detailed description and illustration in Takagi, 2007a.
