Etymology. The specific name anguliloba is derived from the Latin nouns angulus meaning angle or bend, and lobus meaning lobe or rounded projection, reflecting the strong angle/elbow on the anterior side of the surstylus.

Remarks. Females of P. anguliloba , P.lustrum , P. nitens , P. rectiloba , P. silvestris , P. wheeleri can only be reliably identified through sequencing.
