On Sparna macilenta ab. apicemaculata Gilmour, 1954

According to Gilmour (1954): “This new form only differs in principal from the typical form in possessing two small blackish maculae in each elytron at about the apical quarter, the larger, more elongate lies between the two longitudinal carinae, the smaller, slightly oval one, just lateral to the outer carina. Actually, it is Sparna macilenta ab. apicemaculata that agrees very well with the holotype, and not “the principal form” sensu Gilmour. The prothorax of this “principal form” is notably larger than in the holotype, indicates it could be a different species. We did not find this kind of variation in other species of Sparna sensu auctorum . Unfortunately, Gilmour (1950, 1954) did not describe the scape and presence or absence of humeral carina in all species of Sparna , two diagnostic features in the group.
