Thyphlolepta extensa LeConte 1851

Thyphlolepta extensa LeConte, 1851 Thyphlolepta extensa LeConte, 1851: 319 (type locality: Isthmus of Panama). Thyphlolepta extensa – Diesing 1862: 522 (mentioned only). — Lang 1884: 611 (mentioned only). — Faubel 1984b: 240 (identification keys). Distribution Isthmus of Panama. Habitat Benthic. Remarks LeConte (1851) and Diesing (1862) classified Thyphlolepta extensa as a species incertae sedis within the Turbellaria clade, while Lang (1884) and Faubel (1984b) placed the taxon within the order Polycladida, classifying it as a species incertae sedis. However, none of these authors made any comments that could be taken into account to amend the status of the species. LeConte (1851) made a partial description of the species, in which he described a flat body, a purple or light brown dorsal coloration, and intestinal tubes. The present study suggests the collection of specimens of the species to make a complete redescription of the species, as well as to define the status of the species.
