Key to the instar larvae of Hydraenidae  occurring in Cuba

1. Frontal sclerite of head capsule with egg-bursters ( Figs. 16View FIGURE 16 a, b; 22a, b).............................. first instar larva

1’ Frontal sclerite of head capsule without egg-bursters ( Fig. 4View FIGURE 4 a)..................................................2

2. Lateral abdominal areas of segments I to XVII with dorso- and ventrolateral sclerites clearly differentiated from dorsal and ventral sclerites. Pronotum only with three discal setae. Maximum body width at the level of head capsule...................................................................................................... first instar larva

2’ Abdominal dorso- and ventrolateral sclerites not clearly differentiated from dorsal and ventral sclerites in some segments; at least abdominal segments VI to VIII bearing only dorsal and ventral sclerotized plates. More than three setae on pronotal disc. Thoracic segments with approximately same width as head capsule or wider..................................... 3

3. Abdominal dorso- and ventrolateral sclerites clearly differentiated, not fused with their respective dorsal and ventral sclerites, at least in the two first abdominal segments. Thoracic segments of approximately same width as head capsule.................................................................................................. second instar larva

3’ Abdominal segments bearing only dorsal and ventral sclerotized plates. Maximum body width at the level of pro- or mesothorax.................................................................................... third instar larva
