Psylliodes anatolicus Gök and Ç i lb i ro ğ lu, new species ( Fig. 1A–E )

Type specimens, Holotype: ( Male ): “South­west Turkey, Isparta, Gelendost, Madenli village (38° 09' 00" N, 31° 10' 30" E), 1050 m, 18.06.2003, leg. A. Gök ”. The holotype is deposited at Gazi University Zoology Museum ( GUZM), Ankara . Paratypes (6 males, 8 females): same data as holotype; 1 male , " Burdur, Gölhisar­Dirmil road, about 10 km (37° 08' 00" N, 29° 30' 00" E), 950 m, 19.06.2003, leg. A. Gök ", 5 males, 8 females , " same locality as holotype, 26.06. 2003, legs. A. Gök and E. G. Çilbiroğlu . Paratypes are deposited at Süleyman Demirel University , Biology Department, Isparta, Turkey .

Etymology. The new species is named after the older name of Turkey ( Anatolia), where the holotype and paratypes were collected.

Diagnosis. The most evident differences of the new species, Psylliodes anatolicus , from its closest relatives are the following features; body subrobust, rust brown in color, especially adjacent parts of scutellum prominently dark brown; in some samples about apical one seventh of aedeagus slightly constricted ( Fig. 1B ).; ductus of spermatheca short, making nearly right angle to receptacle ( Fig. 1E ). Also, the new species differs from others by some measurements as shown in table 1.

Description. Measurements (mm). Males: Lb = 2.37–3.12; Le = 1.75­2.21; We = 1.20–1.75; Lp = 0.48–0.65; Wp = 0.81–1.01; La = 0.94–1.10; Le/Lp = 3.21–3.60. Females: Lb = 2.28–3.38; Le = 1.62–2.47; We = 1.10–1.95; Lp = 0.48–0.71; Wp =0.71– 1.04; Ls = 0.20–0.28; Le/Lp = 3.37–3.86.

Head: vertex usually impunctate; antennal calli distinct, slightly connected and forming obtuse angle to each other; orbital line evident; frontal ridge wide and flattened.

Antennae: Segments 1­5 light yellow, the remaining ones light brown. Segments 1 and 10 equal, longest (in males 0.16–0.21, in females 0.16–0.19 mm), distinctly longer than 4 (in males 0.14–0.16, in females 0.12–0.15 mm), and 4 longer than others.

Pronotum: convex, narrows towards anterior from dorsal view; about 1.6 times wider than long, base slightly narrow than elytral base; punctuation dense, fine and shallow; background with extremely, finely shagreened texture.

Elytra: elongate, gradually tapering apically, about 1.4 times longer than wide, widest at just behind the humeral calli; surface shiny and punctuate; punctuation large­sized, forming regular longitudinal rows, background texture smooth; humeral calli developed; epipleura with yellowish, long and sparse hairs towards apical.

Venter: black with light pubescence throughout.

Legs: fore and middle legs completely light yellow; second tarsal segments of fore and middle legs smaller and narrower than first and third; metatibia reddish brown, lighter than metafemora, metatarsi lighter brown.

Male Genitalia ( Fig. 1A–D ): in ventral view almost parallel­sized, about five times longer than broad; apex slightly triangular with broad and poorly developed apical tip ( Fig. 1A ); in some samples, approximately apical one seventh of aedeagus slightly constricted ( Fig. 1B ); ventral groove deep, reaches to basal opening; in lateral view, apex distinctly curved dorsally ( Fig. 1C ); in dorsal view, ligula typical, basally wide, terminally truncate ( Fig. 1D ).

Female Genitalia ( Fig. 1E ): receptacle of spermatheca long, with transverse wrinkles in distal part, inner side of receptacle concave; pump slightly narrowed apically; ductus short, attached to lateral side of receptacle, making nearly right angle to it.

Variation: some specimens have the vertex with a few fine, sparse punctures; also, aedeagus varies within the male paratypes in the shape of apex. In some paratypes, apical one seventh of aedeagus is more evidently constricted than others as shown in Fig. 1B .
