Biologi
<p>Notes:</p>Shoemaker identified Lanceola pirotti as a different species, but a review of abundant material reveals that these differences are variably expresed or only some discernible. Thus individual specimens could actually be included with certitute under L. pirlotti while others occupy an intermediate position between L. pirloti and L. clausi. There is no adequate justification for such an identification, and L. pirlotti should be considered a subspecies of the highly variable L. clausi. [Shoemaker, 1945].
