Meiotic analyses of species of the tribes Issini (Figures 1–7) and Parahiraciini (Figure 8), (n = 13 bivalents + X) with different cytogenetic techniques. 1 Conosimus coelatus, a diakinesis with standard and b AgNOR-staining. Arrows point to “secondary” constrictions (gaps) (a) and empty arrows NORs (b) point to the largest autosomal pair 2 Kervillea scoleogramma, a diakinesis and b metaphase I with standard staining. Arrows point to "secondary" constrictions on the largest autosomal pair (a) 3 Latematium latifrons, metaphase I with standard staining 4Mycterodus (Mycterodus) drosopoulosi, diakinesis with standard staining 5Mycterodus (Semirodus) sp., diakinesis with C-banding. a Arrows point to C-bands on the largest and medium-sized bivalents. In the largest bivalent, C-bands are located at the terminal or b at the proximal (chiasmate) parts of chromosomes. Short arrows point to C-bands 6 Sarnus sp., a metaphase I with standard staining and b diakinesis with AgNOR-banding. Arrows point to NORs on the largest autosomal pair 7 Thionia obtusa, diakinesis with standard staining. Arrows point to “secondary” constrictions on the largest autosomal pair 8 Thabena sp. a diakinesis with standard staining, and b diplotene with CMA3-banding. Arrows point to “secondary” constrictions (a) and asterisks mark CMA3-positive, GC-rich regions (b) of the largest autosomal pair. Scale bar =10 µm.
