lected them. Apart from these aforementioned genera, the only known oxyteline larva with this character state is Crassodemus. KEY TO GENERA OF OXYTELINAE This key is not intended to be a practical identification guide, rather a system­atic one, which helps workers determine whether a particular species belongs to a given genus or not. This goal can only be achieved by often relying on anatomical characters (necessitating permanent preparations or dissections). Since the super­ficial similarity between unrelated taxa can be great, it is unavoidable that less ex­perienced workers examine at least a few of the key features of the genital seg­ments, which can unequivocally determine the placement of a specimen. A more practical approach would require the use of external morphological characters that can vary and result in confusion - not counting the (great) possibility of previously unseen species possessing yet undiscovered character states. 1 Abdominal segments III to VI with one pair of laterosclerites per segment. (Deleasterini) 2 Abdominal segments III to VI with two pairs of laterosclerites per segment 7 2 Procoxal fissure fully open. Tibia with longitudinal row of spines 3 Procoxal fissure nearly or quite closed. Tibia without longitudinal row of spines absent 4 3 Pronotum distinctly convex in cross-section, laterally not margined; elytra without rows of punctures. Tergite VIII with serrate posterior margin. Body surface more or less dull Deleaster Pronotum flat and distinctly margined laterally; elytra with rows of punc­tures. Tergite VIII with smooth posterior margin. Body surface shining, ex­cept for the impressions and rows of punctures on head, pronotum, and elytra (Fig. 108) Platydeleaster 4 Body, especially dorsum, with numerous scale-like setae 5 - Body without scale-like setae 6 5 Scale-like setae not plumose. Tarsal formula 5-5-5 Oxypius - Scale-like setae plumose. Tarsal formula 3-3-3 Euphemias
