Sericostoma pinargozu sp. n.

( Figs 35–39 View FIGS )

Material. Holotype male: Turkey, Isparta, Yenişarbademli, Pınargözü Cave , 1531 m, 37°41′N, 31°18′E, 21.vii.1998, (CD: U-113); leg. and coll. SİPAHİLER. GoogleMaps

Paratypes: 7 males, 2 females: Same data as holotype GoogleMaps .

General description. Antennae and maxillary palps and wings brown, dorsal thorax dark brown, maxillary palps gradually enlarged ( Fig. 35 View FIGS ), legs pale brown, length of each anterior wing of male 10.5–11.0 mm (mean = 11.1 mm, n = 5), of female 11.5–12.0 mm (mean = 11.8 mm, n = 3).

Description of male genitalia ( Figures 36–39 View FIGS ). In lateral view, segment IX dilated laterally, anterolaterally rounded in 75° angle. Preanal appendages long, oval. In lateral view, lateral prolongations of segment X each long, basoventral branch triangular, acute; mesoventral branch 2/3 as long as dorsal branch, about as narrow as dorsal branch, somewhat curved ventrad basally so that this branch widely separated from dorsal branch, directed caudad, and acute apically; dorsal branch rather narrow, directed caudad and somewhat ventrad, acute apically, in dorsal view with small subapical angle on mesal edge; in dorsal view, both mesoventral and dorsal branches rather thin and long. In lateral view, basal portion of each inferior appendage large and rather long; dorsal branch broadly dilated apically; in ventral view, ventral branch sinuous, enlarged at tip, curving mesad, apex pointed;. In lateral view, phallic apparatus is dilated distally, about 2.0X as broad as base; basoventral carina triangular, about as long as thickness of base, with apex slightly curved caudad.

Diagnosis. Sericostoma pinargozu sp. n. similar to S. taskent sp. n., for which diagnostic differences are provided with that species, above. Sericostoma pinargozu also resembles S. yuvarlakcay sp. n. The following differences are seen in the male genitalia: in S. pinargozu sp. n. the mesoventral branch of each lateral prolongation of segment X is long, nearly 2/3 as long as the dorsal branch with the distance between them rather large; the preanal appendages are slightly longer; the ventral branches of the inferior appendages are slightly more slender, slightly sinuate. In S. yuvarlakcay sp. n., the mesoventral branch is shorter, nearly 1/2 as long as the dorsal prolongation; the distance between them is narrower; the ventral branches of the inferior appendages are straight and somewhat thicker.

Remarks. Sericostoma pinargozu sp. n. occurs in a mountain stream with rapidly flowing water which comes from a cave.
