Material examined. Holotype. 1 male pupa, holotype: Sardinia, Gola di Gorruppo; 40°11.122'N , 9°30.104'E ; 350 m a.s.l.; 28.03.2001; leg. Monika Hess, Ulrich Heckes; currently in coll. W. Graf, will deposited in the Biologiezentrum des Oberoesterreichischen Landesmuseums, Linz, Austria. Type locality. Italy, Sardinia. Diagnosis. Morphology of the male terminalia suggests placement of the new species in Wormaldia . The species is unique in the European Trichoptera fauna, and easily differentiated from all other Wormaldia species by the combination of the following characters: (1) presence of median subtriangular protrusion in the distal half of the harpago, (2) membraneous dorsoproximal portion and trilobate lateral portions of segment X, and (3) distinct sclerotized structures visible on the invaginated phallus. Description. Adults (in pupa). Habitus dark, sclerites and tergites brown; cephalic and thoracic setal areas pale; cephalic, thoracic and abdominal setation dark brown; legs light brown, proximally darker; haustellum and intersegmental integument pale cream. Wings brown mottled with golden patches. Male maxillary palp 5-segmented. Spurformula 2 -4- 4 in males. Male genitalia (Fig. 1 A-D ). Segment IX in lateral view subrectangular, bulging anteriad; dorsal quarter reduced to a narrow transverse bridge, ventral 3/4ers broad (Fig. 1A). Segment X in lateral view trilobate: unpaired dorsal lobe strongly convex with a bicuspid apex, dorsoproximally membraneous; 1 lateromedian lobe, subovate, pointed on either side; 1 ventral lobe, posteriad, pointed on either side (Fig. 1A, B). Superior appendages suboval, curved dorsad in lateral view, flat with a rounded apex in dorsal and ventral view (Fig. 1A, C, D). Invaginated phallus terminally with a dorsal pair of sclerotized, laterad divergent tines and a ventral sclerotized plate; internally with 4 distinct tines (Fig. 1A, D). Coxopodite subovate in lateral view, ventrally with a sharp mediolaterad ridge (Fig. 1A, C). Harpago subovate in lateral view, in ventral view distally with a median subtriangular serrated protrusion flattened dorsoventrally (Fig. 1A, D). Figure 1. Male genitalia of Wormaldia sarda sp. n. A right lateral view, intact B right lateral view, superior appendage removed C ventral view D dorsal view. Mature pupa (Fig. 2 D-F ). Mandibles tubular, dilated at the apex (Fig. 2E,F). Abdominal dorsal sclerites as in Fig. 2D. Figure 2.

Scale bars: 100 µm (B); 50 µm (C, D). Female and larva unknown. Etymology. The species epithet refers to the island of Sardinia, the type locality.
