KARYOTYPE OF HYMENOLEPIS CITELLI (CESTODA: CYCLOPHYLLIDEA)

The karyotype of Hymenolepis citelli (McLeod, 1933) has been studied using early cleavage embryos isolated from 9-day-old worms that had been pretreated for 4 h at 37.5 °C in culture medium containing 0.03% colcemid. A diploid number of 12 was observed.
