Hydroptila santarosa sp. n.

( Fig. 6 View Figure 6 )

Diagnosis. This new species appears most similar to H. cottaquilla Harris and H. bribriae Harris , with the tenth tergum in all these species trilobed. However, the phallus in H. santarosa is more similar to that of H. bribriae . The new species differs from H. bribriae in the structure of segment X, particularly in lateral view, and in the shape of the subgenital plate.

Description, male. Length 2.1-2.3 mm. 28 antennal segments. Brown in alcohol. Abdominal segment VII annular with short posteroventral process. Segment VIII annular. Segment IX rounded anteriorly in lateral view, widening posteroventrally; in dorsal and ventral views with deep mesal incision; ventrally with posterior margin incised laterally. Segment X in lateral view rectangular, narrowing posteroventrally, thin median process from dorsum; dorsally trilobed, lateral lobes acute apically, mesal lobe rounded. Inferior appendages boat-shaped in lateral aspect, sclerotized point apically; in ventral view, wide basally and bearing elongate lateral seta, narrowing to acute apex with is turned outward. Subgenital plate in lateral view as wide as segment X, rounded apically, sclerotized ventrally; in ventral view triangular, narrowing mesally and bearing pair of stout setae. Phallus with basal section elongate, narrowing subapically, apical section elongate, basally tubular, distally sharply angled then tubular; ejaculatory duct thin, and enclosed within phallic shaft; short paramere encircling shaft below juncture of apical and basal sections of phallus.
