Remarks

Thor (1906) introduced this name for specimens having the mediodistal seta on P-3 closer to the dorsodistal one, without giving any further morphological details or discussion. Designating the taxon as “nov. var.”, Thor left the question open whether he considered it a separate (sub)species. In the redescriptions of L. porosa and L. obscura , the position of this seta is subject to considerable individual variability, while a rather extreme case of dorsal shifting of the mediodistal seta P-3 is found in specimens belonging to L. gibbosa (P-3 A/B>1.6). In the absence of further morphological information and due to the lacking type material, there is no reliable reason for reanimating L. porosa dorsalis . It cannot be interpreted as a junior synonym of L. porosa (as proposed in Viets 1956), and it has to be considered a nomen dubium.
