Systematics: Protodiaspis sulcata is quite similar to P. emoryi and somewhat similar to P. colimae. It differs from the former in the strongly furrowed and elongate pygidium and from the latter in the very few and very minute ducts (Ferris, 1942).
Structure: Adult female about 0.7 mm long, elongate oval, the narrow pygidium projecting posteriorly. Derm for the most part quite heavily sclerotized, there being merely a short area between the pygidium and the remainder of the body that is membranous. Pygidium strongly sclerotized, forming more or less parallel-sided and apically rounded plate which is divided longitudinally by furrows, both dorsally and ventrally into 5 lobe-like areas, the apices of which project very slightly from the margin. 2nd stage heavily sclerotized dorsally and ventrally, its pygidium without lobes and apparently without ducts, but irregularly furrowed (Ferris, 1942).
General Remarks: Detailed description and illustration by Ferris (1942).
