Lebertia (Pilolebertia) porosa britannica Thor, 1906: 776 .

Nomen dubium.

Type series

Missing. Type locality: “ England, Schottland ” “… besonders unter den englischen Exemplaren einzelne Individuen …”; no date, no information on number of specimens. No material available.

Remarks

Having introduced L. porosa britannica as “nov. var.”, it is unclear whether Thor intended to assign the taxon (sub)species value. In his description, Thor (1906) gave the name to specimens having a character combination not found in the material studied here, stating that Ac-3 was “nearly as long as Ac-1 and -2”. In other taxa of the subgenus, Ac-3 is distinctly shorter. However, as Thor did not describe any further morphological details, and in view of the absence of locality information and type material, L. porosa britannica cannot be considered a junior synonym of L. porosa (as proposed in Viets 1956), but is to be treated as a nomen dubium.
