In most holometabolous insects, sex determination involves differentiated sex chromosomes of the XY type (ZW, with heterogametic females in Lepidoptera). In Coleoptera (beetles) a general karyotype with meioformula 2n = 9 + XY is prevalent in the approximately 3,000 species studied to date (Smith and Virkki 1978Citation ; Petitpierre 1996Citation ), but the genetic system of Cicindelidae (tiger beetles) is unusually diverse, with many species exhibiting multiple sex chromosomes, XnY, where n varies between 2 and 4. During meiosis these heterosomes form a characteristic rosette-like multivalent linked by telomeric connections without forming chiasmata between the various X chromosomes (Giers 1977Citation ). The multiple sex chromosome system is widespread in cicindelids and is found in both the recognized subfamilies, including the Cicindelinae with a multiple system, which has been described for 55 species mostly in the species rich genus Cicindela (sensu lato), and the Collyrinae with three representatives studied . . .
