FIGURE 3 in Polytene chromosomes of Simulium (Psaroniocompsa) daltanhani (Diptera: Simuliidae) from Central Amazonia, Brazil

FIGURE 3. Chromosome III of Simulium daltanhani. Bl = blister, bm = basal marker, C = centromere, Ca = capsule, Em = end marker, IIIL = long arm, IIIS = short arm. Section numbers indicate regions homologous with S. ulyssesi. Brackets on IIIL indicate the large, fixed inversion, relative to S. ulyssesi, that inverts the basal and end markers.
