Caedicia flexuosa ( Fig. 19 )

2n=15 (2m + 12t +Xt)

Specimens examined: R88-18, -21, -60, -65, -94, -98, -120, -129, -170, 2006-5, -2007-10

The karyotype ( Fig. 19a ) and spermatogonial metaphase ( Fig. 19b ) present one pair of small metacentric, 6 pairs of telocentrics and the large telocentric X ( Fig. 19c ). The chromosome system of this species is 2n=15 (2m + 12t +Xt) in the male. There are 7 autosomal bivalents and the X at first metaphase ( Fig. 19c ). At first anaphase, the X moves to one pole with 7 autosomes and the other without X ( Fig. 19d ). As the result of the first division, two types of second metaphases, such as 6 autosomes with X ( Fig. 19e ) and 6 autosomes ( Fig. 19f ) are formed.
