Keys

• WolffCl2010: pp.232 ( Adult (F) ) [Key to Diaspidistis, based on the characters of adult females]
• Ferris1942: pp.SIV-446:62 ( Adult (F) ) [Key to species of Pseudoparlatoria]

Remarks

• Systematics: This species was transferred to Diaspidistis by Wolff & Claps (2010) because, in addition to the dosal glands cited by Ferris (1942), it also has marginal and submarginal tubular glands of similar size and shape.
• Structure: Adult female pygidium somewhat elongate, broadly rounded apically. Median lobes moderately large, separated by slightly less than the width of one of them and with a bifurcate gland spine between. Median and 2nd lobes well developed, distinctly bilobulate, the outer lobule in each but slightly smaller than the inner, the whole lobe nearly equal to a median lobe in width, but slightly shorter. Margin of the pygidium with very small gland spines at frequent intervals (Ferris, 1942).
• General Remarks: Detailed description and illustration by Ferris (1942).
