Helicopsyche lusitanica . Diagnosis. Dorsally, the head capsule has only 17 pairs of primary setae. The propleuron in lateral view has a sharply-angled dorsal outline; its anterior process is only slightly concave dorsally, long and strongly tapering ( Fig. 39 ). The submentum posterior edge is only slightly narrower than its anterior edge ( Fig. 40 ). The larva was described in detail by Vieira-Lanero et al. (2001).
