FIGURE 4. Chromosomes of Prosimulium italicum from Italy (Campania) A. IIS of female larva, showing fixed inversions IIS-3 and IIS-4 of P. italicum (also present in P. hirtipes) and breakpoints of autosomal polymorphism IIS-12 in P. hirtipes; C = centromere, RoB = ring of Balbiani. B. IIIL (except basal sections) of female larva, showing standard sequence. Breakpoints are indicated for autosomal polymorphisms IIIL-20, 21, 22, and 23 in P. hirtipes, and IIIL-24 in P. italicum; "s" = shield, "t" = triad. C. Centromere region (CI) of chromosome I, showing band differential (*) and associated unpairing in section 19'. C = centromere, N.O. = nucleolar organizer.
