Key to puparia of Crenidorsum species from Taiwan

1. Abdominal segments not rhachisform; median rhachis with extending lines absent on abdominal region; the median length of abdominal segment VII little smaller than the VI ......................................................................................... 2

-. Abdominal segments rhachisform; median rhachis with lines extending onto submedian area of abdomen; the median length of abdominal segment VII equal to VI.................................................................................................. 3

2. Cephalic, meso- and metathoracic setae, eighth abdominal and caudal setae nearly half the length of vasiform orifice ( Fig. 49 ); subdorsum and submargin with prominent lines radiating from margin ......................................... alpinus

-. Cephalic, meso- and metathoracic setae, eighth abdominal and caudal setae nearly three times longer than the vasiform orifice length ( Fig. 52 ); subdorsum and submargin without prominent lines .................................. elatostemae

3. Puparium broadly oval; cephalic, meso- metathoracic and eighth abdominal setae equal to or nearly two times longer than the vasiform orifice; submedian area of abdominal segments II–V usually with 3 pores and associated porettes; inner wall of the orifice irregular ( Fig. 60 ) ........................................................................................... micheliae

-. Puparium elongate; cephalic, meso- metathoracic and eighth abdominal setae more than three times longer than the vasiform orifice; submedian area of abdominal segment II–V always with only 1 pair of pores and associated porettes; inner wall of the orifice smooth ( Fig. 63 )............................................................................................. turpiniae
