Remarks
- Systematics: Protodiaspis praetexta is similar to P. pulchra. A key characteristic for their separation is the absence of the morphologically marginal series of gland spines which in P. pulchra extends from the pygidium to the antennae but in P. praetexta is represented only by one or two spines between the spiracles and occasionally one near each antenna, some specimens with part or all of these lacking (Ferris, 1941d).
- Structure: Adult female 0.5 mm long, more or less turbinate, at maturity with the prosomatic region sclerotized both dorsally and ventrally. Pygidium rather short and broad, with the dorsal surface sclerotized and with its surface marked by somewhat vermiculate lines. 2nd stage with 2 well defined pairs of pygidial lobes, these toothed apically and the 2nd pair distinctly bilobulate (Ferris, 1941d).
- General Remarks: Detailed description and illustration by Ferris (1941d).
