B. kewense, reproduction by scissiparity—the shed tail fragment.
The free tail fragment is immediately motile. It develops a head and pharynx within seven to 10 days, and within two to three weeks it is adult in form and behaviour (Connella & Stern, 1969). Asexual reproduction in B. kewense and some other land planarians is considered to underlie the colonizing success of these species (Hyman, 1951, p. 163).
