The form has 211 to 220 body annuli; seven caudal annuli up to the autotomy constriction (at which the tail is autotomized in one specimen); 28 to 29 caudal annuli from the cloaca to the caudal tip which is faintly compressed lateraly; 12 to 14 dorsal and 14 to 16 ventral segments to a midbody annulus; and two precloacal pores.
