Key to puparia of Aleurotrachelus, Cohicaleyrodes and Crenidorsum *

1. Puparial submedian/subdorsal area with crescent-shaped scallops (Figs 49, 52), at least on cephalic region or one side of well-defined subdorsal longitudinal ridge (exception C. marginale Russell) or in the form of wavy markings in the Oriental species; the area around vasiform orifice not swollen and not elevated; [mostly Neotropical and Oriental] ........................................................................................................................................................ Crenidorsum

-. Puparial submedian/subdorsal area without crescent-shaped scallops but a pair of cuticular longitudinal folds or only longitudinally pigmented area or furrows made up of two parallel lines present (Figs 1, 13, 25); the area around the base of orifice swollen or posteriorly well elevated (Fig. 24) ...................................................................................... 2

2. Puparia mostly black, elliptical or octahedral, rarely oval; marginal tooth usually conical, or irregular or sharply pointed, each tooth with a wax secreting gland or at least transverse membranous area at base (Fig. 32); the first abdominal ‘pseudosetae’ present near median area in some Australian species; a median longitudinal ridge usually present on cephalothorax of most Asian species. ................................................................................ Aleurotrachelus

-. Puparia usually colourless, pale yellow or dark brown, usually broadly oval; margin toothed or crenulate, teeth without wax secreting glands or transverse membranous area at base; first abdominal setae absent; a median longitudinal ridge absent on cephalothorax..............................................................................................................
