Description. Male. Length of forewing 2.1 mm. Colour (in alcohol): brownish.

Male genitalia. Segment IX long, with deep dorsal and ventral excisions; antero-lateral lobes elongated with rounded apex in lateral view; posterior margin with long triangular postero-lateral projection rounded apically in lateral view. Segment X long, sclerotized along lateral margins, membranous in middle; in dorsal view narrow basally and broadened distally with acute apico-lateral tips and rounded mesal lobes. Lateral projections of segment X asymmetrical, long, their distal halves bent upwards; right branch shorter, simple; left branch long- er, bifurcated in middle, outer additional long bristle-like branch arising from the fold of main branch and directed upwards and outwards. Inferior appendages long, narrow, slightly broadened in middle; curved downwards in lateral view; straight, tapered to acute apex in ventral view. Phallus tubular, long and thin, with short spiral paramere in middle.

Differential diagnosis. Hydroptila hodkovae sp. nov. belongs to the occulta species group. It differs from other similar species in this group, such as H. fonsorontina Botosaneanu & Moubayed, 1985 , and H. ernstreichli Malicky, 1998 , mainly by the shape and arrangement of the asymmetrical lateral projections of segment X and the inferior appendages.

Etymology. This species is dedicated to Zdenka Hodková, Praha, who organized the Czech Biological Expeditions to Iran in 1997-2000.
