Caedicia webberi ( Fig. 18 )

2n=21 (20t +Xt)

Specimens examined: R86-85, -102, -109, 88-214, 2004-26, -27, -31, -43, -2005-3, 2006-6, -7

The karyotype of this species consists of one pair of large and 9 pairs of medium to small telocentrics and the largest X telocentric ( Fig. 18a ). Thus, 2n= 21 in the male. At first metaphase there are 10 bivalents and the X ( Fig. 18b ). At first anaphase, the X moves to one pole with 10 autosomal entities and the other with 10 autosomes ( Fig. 18c ). As a result of the first division, two types of second metaphases are formed. One has 10 autosomes with X ( Fig. 18d ); the other is with 10 autosomes ( Fig. 18e ).
