The presence of one or two spurs in the tibiae seems to be a very well fixed character and have been used as a diagnostic character for distinguishing several genera in other subfamilies as Sphinctus in Tryphoninae and Periope in Metopiinae. In a study carried out in a protected area of Spain, two specimens of Cremastinae with one spur in one middle tibia and two spurs in the other middle one have been found. With this morphology their taxonomical position in the subfamily is uncertain, as a consequence in this communication we analyze the repercussion of considering this diagnostic character as a variable feature for distinguishing Eucremastus and Noxocremastus from other Cremastinae genera.
