Limnephilus malickyi Sipahiler 1992

( Figs 23–29 )

Material examined. Turkey, Niğde, Aladağlar, Yedigöller (CD: R-277), Direkgöl , 37°50´N, 35°11´E, 3200 m, 30. Viii.1990, 19 males, 18 females, leg. and coll. Sipahiler.

General description. As for L. bipunctatus except antennae, legs, and wings dark brown; forewings with pale brown spots especially dense apically ( Fig. 1E ). Length of each anterior wing of male 7–10 mm (mean = 8.7 mm, n = 5) of female 8–10 mm (mean = 9.0 mm, n = 4). Females brachypterous, forewings reaching segments VIII or IX; male forewings also shorter, only slightly longer than abdomen.

Male genitalia ( Figs 23–26 ). Tergite VIII with transversely broad and longitudinally short spinulose zone, 1/4 as long as broad, covered with dense spines. Segment IX in lateral view broad (longitudinally long), 4 times as long as ventral margin; preanal appendages oval, 1/3 as tall as long; intermediate appendages in dorsal view rather straight and directed toward posterior, in caudal view ventromesal parts about as broad as long. Inferior appendages broad in lateral view, about 2/5 as broad as length of lateral parts of segment IX, with apex pointed and directed dorsad; laterally apical end of parameres with two long basal setae at base; from base to apex ten setae which become longer towards apex; on inner surface shorter setae found.

Female genitalia ( Figs 27–29 ). In dorsal view, tergite IX nearly trapezoidal, broad at base and narrowed on mid-length and with apicomesal edge truncate; tubular pieces short, triangular, widely separated; in lateral view, side lobes of segment X broad at base, triangular; in ventral view, median lobe of vulvar scale triangular, 3/4 as wide basally as long.

Remarks. Limnephilus malickyi is an isolated endemic species found on the highest part of the Taurus Mountains ( Sipahiler 1992). It resembles L. bayburt sp. n. but can be distinguished by diagnostic characters discussed in the Remarks for that species (above).

L imnephilus caucasicus Schmid 1955

( Figs 30–36 )

Material examined. Turkey, Rize, Çamlihemşin, Verçenik Mountain, Küçük Göl , 2700 m, 40º43´N, 40º54´E, 20.viii.1992, 6 males, 1 female (CD: R-466), leg. and coll. Sipahiler.

General description. As for L. bipunctatus except antennae, maxillary palps, legs and wings brown; forewings of male ( Fig. 1F ) each 9.0–10.5 mm (mean = 10 mm, n = 4); of female each 9 mm (n = 1).

Male genitalia ( Figs 30–33 ). Posterodorsal spinulose zone of tergite VIII short, 3/8 as long as broad, its sides round and covered with dense spines, median part with spines less dense. Segment IX in lateral view broad (longitudinally long), 2.5 times as broad (long) as inferior appendages. Preanal appendages broadly oval, 4/5 as tall as long. In lateral view, intermediate appendages broad in basal 2/3, tapered in apical 1/3, directed posterodorsad, in dorsal view tapered and curved laterad, in caudal view ventromesal part rather small, about as long as broad. Inferior appendages short, 2/3 as tall as broad. Parameres of phallic apparatus each with apical part rather short, 1.5 times as long as apical part of phallicata.

Female genitalia ( Figs 34–36 ). Tergite IX rounded on posteromesal edge. Tubular pieces very small, transverse in dorsal view, in lateral view oval on apical margin of tergum IX. Median lobe of vulvar scale broad at base, 1.5 times as long as base, convex laterally for 3/4 length, narrower and truncate apically.

Remarks. Limnephilus caucasicus lives in the lakes of high mountains of northeastern Turkey. It resembles L. bercalan sp. n. The following differences are seen in the male genitalia: In L. caucasicus the spinulose zone of tergite VIII is large with the sides roundly dilated and covered with dense spines, but in L. bercalan sp. n. the spinulose zone of tergite VIII is small with its sides narrow and pointed and with its surface sparsely covered with spines. In L. bercalan sp. n., in lateral view, the intermediate appendages are rather long and slender beyond a short base, but in L. caucasicus they are much shorter beyond a longer and somewhat thicker base; in L. bercalan sp. n., in dorsal view, they are gradually curved laterad through their total length, but in L. caucasicus they are convergent for 2/3 of their length and then divergent subapically. Inferior appendages in L. bercalan sp. n. are nearly as broad (longitudinally long) as lateral regions of segment IX, but they are only 2/5 as broad (long) as segment IX in L. caucasicus .
