Nomen dubium. Type series Missing. Type locality: Italy , Lago Maggiore, coll. Thor; no date, no information on number of specimens. No material available. Remarks Thor (1906) gave this name to specimens having a coxal field and appendages with an intense greenblue coloration. This is exactly the same colouration as was the basis for defining L. obscura and it remains unclear why Thor published this name. In the absence of type material, L. porosa italica cannot be considered a junior synonym of L. porosa (as proposed in Viets 1956 ), and it has to be considered a nomen dubium.
