Tinodes voriseki sp. nov.

( Figs. 6-13 )

Type material. HOLOTYPE: J, IRAN: AZARBAIJAN GHARBI prov., springfed brooks, Rud-e Saruq River valley 10 km SE Chuplu, 36°28′N 47°02′E, 1700 m a.s.l., 2.x.1998, P. Chvojka leg. ( NMPC) . PARATYPES: the same data, 2 JJ ( NMPC), 1 J ( HM) ; the same data except 10.v.2006, 1 J ( NMPC) .

Additional material examined. IRAN: HAMADAN prov., springfed brook nr. Alanje 15 km W Asadabad, 34°45′N 47°58′E, 1680 m a.s.l., 5.-6.x.1998, P. Chvojka leg., 1 J ( NMPC).

Description. Male. Length of forewing 4.8-5.0 mm. Colour (in alcohol): Body, wings, and legs yellowish brown.

Male genitalia. Ventral part of segment IX, in lateral view with straight ventral margin, antero-ventral process triangular, posterior end truncated. Segment X with sclerotized tonguelike dorsal plate, membranous ventrally. Paraproctal processes rod-like, slightly tapered to apex, jointed basally, with two pairs of strong, long spurs placed on dorsal side subapically and in middle. Superior appendage long and thin, curved. Coxopodite broad with apicoventral triangular projection; harpago simple, apex obliquely truncated with acute ventromesal tip in ventral view. Basal plate of inferior appendages with long proximal apodeme and large paired distal process, the latter bearing two dorsal lobes and one ventro-apical lobe, rounded dorsal lobes separated by broad U-shaped excision (lateral view). Phallus rod-like, distal tubular part curved ventrally.

Variability. The specimen from Alanje is slightly different from the type specimens from Chuplu. It has almost fused dorsal lobes of the distal process of the basal plate of inferior appendages (lateral view, Fig. 12 ), and the phallus bears a ventral cluster of five additional spines in the middle ( Fig. 13 ).

Differential diagnosis. This species is similar to T. amadai Schmid, 1959 , and T. tohmei Botosanenu & Dia, 1983 , but can be easily distinguished by the shape of the process of the basal plate of inferior appendages and by the paraproctal processes.

Etymology. This species is named after Martin Voříšek, Praha, an excellent expedition driver.
