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

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 GoogleMaps . Paratypes (6 males, 8 females): same data as holotype; 1 male GoogleMaps , " 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 GoogleMaps , " same locality as holotype, 26.06. 2003, legs. A. Gök and E. G. Çilbiroğlu GoogleMaps . 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 View FIGURE 1 ).; ductus of spermatheca short, making nearly right angle to receptacle ( Fig. 1E View FIGURE 1 ). 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 View FIGURE 1 ): in ventral view almost parallel­sized, about five times longer than broad; apex slightly triangular with broad and poorly developed apical tip ( Fig. 1A View FIGURE 1 ); in some samples, approximately apical one seventh of aedeagus slightly constricted ( Fig. 1B View FIGURE 1 ); ventral groove deep, reaches to basal opening; in lateral view, apex distinctly curved dorsally ( Fig. 1C View FIGURE 1 ); in dorsal view, ligula typical, basally wide, terminally truncate ( Fig. 1D View FIGURE 1 ).

Female Genitalia ( Fig. 1E View FIGURE 1 ): 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 View FIGURE 1 .
