description: Key to puparia of Aleurotrachelus species from Taiwan
1. Marginal teeth triangular, sharply pointed (Fig. 5); dorsal pores densely scattered on submedian area of cephalothorax, laterad of longitudinal folds and abdominal rhachis (Fig. 4), the distance between caudal end of vasiform orifice and posterior end of the puparium more than the orifice length ............................................................... fissistigmae
-. Marginal teeth smoothly crenulate or broadly toothed (Figs 2, 8, 11, 26); dorsal pores not densely scattered on submedian area of cephalothorax laterad of longitudinal fold and abdominal rhachis, if present; the distance between caudal end of vasiform orifice and posterior end of the puparium about equal to the orifice length ........................... 2
2. Puparium octahedral (Figs 25, 31); the median length of abdominal segment VII equal to, or more than half the length of segment VI; a band of microtubercles along lateral longitudinal fold present; abdominal segment sutures not extending on subdorsum; lateral arms on abdomen made up of microtubercles; microtubercles present on subdorsum....................................................................................................................................................... tuberculatus
-. Puparium elliptical or oval; the median length of abdominal segment VII much reduced, less than half the length of segment VI; a band of microtubercles along lateral longitudinal fold absent; abdominal segment sutures extending on subdorsum; lateral arms present, not made up of microtubercles; microtubercles absent on subdorsum ............... 3
3. Puparium yellowish, elongate, marginal teeth square-shaped and broadly separated with incision (Figs 2, 8); eye spots absent; meso-, and metathoracic setae present; a longitudinal row of pores and porettes along lateral longitudinal fold present; lingula exposed (Fig. 3) .......................................................................................................... anonae
-. Puparium black, elliptical, marginal teeth crenulate, conical-shaped, not widely separated by incision (Figs 14, 17, 20, 23); eye spots present, unclear in over bleached puparia; meso-, and metathoracic setae absent; a longitudinal row of pores and porettes along lateral longitudinal fold absent; lingula concealed.................................................... 4
4. Median length of abdominal segment VII equal to, or more than half length of VI; group of pores and porettes absent on metathorax; 3 pairs of pores and porettes on submedian area of each abdominal segment, and abundant (not in rows) on subdorsum/submargin; vasiform orifice typically circular, notched at caudal end (Figs 15, 21); operculum filling 1/3rd of orifice ......................................................................................................................................... maesae
-. Median length of abdominal segment VII much reduced, less than half length of VI; group of pores and porettes present on submedian area of metathorax; one pair of pores and porettes on submedian area of each abdominal segment, and 3 rows on subdorsum/submargin; vasiform orifice subcircular or cordate (Figs 18, 24), not notched at caudal end; operculum almost filling orifice.................................................................................................. pyracanthae
