Poecilimon ilgazi Ünal et Erden, sp. nov.

( Figs. 135–148 , 319–320 )

Type locality. Turkey: Kastamonu Prov., Tosya Distr., Ilgaz Pass , 1650 m .

Description. Male (Holotype). Fastigium of vertex narrow, 2 times narrower than antennal scape, with a weak, narrow dorsal fossa. Pronotum ( Figs. 137, 138 ) with constricted and cylindrical prozona; anterior part of prozona and metazona raised in lateral view; metazoma distinctly widened and slightly flattened in dorsal view; paranota compressed laterally; anterior and posterior margins of pronotum convex in dorsal view, in some males, anterior margin straight; shoulders distinct. Tegmina ( Figs. 137, 138 ) wide, but slightly narrower than hind margin of metazona, reaching the end of second abdominal tergite. Hind femur without ventral spines. Supra anal plate simple, almost as wide as long, rounded at hind margin. Cercus ( Figs. 139, 141 ) slender, basal 2/3 part gently narrowed from the base to the end of this part; apical 1/3 part very slightly incurved and weakly widened; posterior margin with 11 denticles sorted as convex, innermost apical denticle larger; with a single dorsal denticle which is as large as apical one and not reaching beyond the borders of cercus in dorsal view ( Fig. 141 ), and much shorter than apical denticle in posterior view ( Fig. 140 ). Subgenital plate ( Fig. 142 ) twice as long as wide, distal part (section with median carina in ventral view) shorter than proximal part, with a shallow, rounded posterior incision; in some males slightly deeper, but always wider than its depth.

Female (Allotype). Fastigium of vertex narrow, half of antennal scape, with a distinct elliptical dorsal fossa. Pronotum ( Fig. 145, 146 ) almost cylindrical; anterior margin of prozona and metazona very slightly raised, almost straight in lateral view; anterior margin weakly concave, posterior margin slightly convex in dorsal view. Tegmina small, scale-like laterally, fully concealed under pronotum. Hind femur without ventral spines. Supra anal plate 1.4 times wider than long, very narrowly rounded at hind margin, nearly triangular. Cercus simple, conical, weakly incurved near apex; slightly longer than supra anal plate. Subgenital plate ( Fig. 147 ) small, almost triangular, 1.7 times wider than long, with a triangular depression on ventral surface. Ovipositor ( Fig. 148 ) slender, narrow and long, almost twice as long as pronotum, 6.7 times longer than high in the mid part, its ventral margin straight or very weakly convex; its serrated apical part sharply upcurved and pointed at apex, with 10 upper and 10 lower apical teeth; basal fold of lower valve narrow, its ventral margin almost straight or very slightly convex in some females.

Colouration. In dry specimens, green colour replaced with creamish milky-brown. Body ground mainly milky brown, with black spots, black bands, reddish and yellow parts. Face creamish milky brown. Antennae with dense black rings. Dorsal surface of head with small black spots, one larger on occiput in the middle. Prozona of pronotum, all legs including tibias, and abdomen with numerous, small, rounded black spots. Metazona of pronotum reddish in the middle dorsally, with a transversal narrow black band at hind margin, which is wider in male. Tegmina yellow in both sexes, with blackened dorsal surface near to base in male. Dorsal surface of first abdominal tergite in female yellow, with a large black spot at fore margin. In male, anterior margins of the 6th–9th abdominal tergites with a transversal black band, which expands backwards in the mid part; in some males, this band is also seen on the first tergite. In female, anterior margin of second abdominal tergite with a large, and the 6th–9th tergites with narrower transversal black bands which expand backwards in the mid part; in some females, this band is also seen on the other tergites. Ventral surfaces of fore and mid femora and sometimes hind femora with 2 parallel black stripes along their lengths. Hind femur with a longitudinal black band on the outer and sometimes on the inner surface, which weaker or stronger in paratypes. Last abdominal tergite weak, pale reddish. Apical part of male cercus black. Ovipositor yellowish green, turns to dark green in apical serrated part with blackened apical teeth; middle part with small reddish spots in lateral view.

Discussion. This new species is recognizable in the genus by the male cercus and female ovipositor. It is most related to P. bosphoricus s. lat. by the similar general structure of male cercus (previously considered in this species) with a series of posterior denticles and one dorsal denticle. But it is distinct in both sexes. Male cercus of this new species much more slender, long and thin; apical curvature less, begins nearer to middle of the cercus; apex weakly widened; dorsal single denticle smaller and shorter [in P. bosphoricus bosphoricus , male cercus ( Fig. 116 ) much stouter, short and wide (compare cercus with the width of last tergite in Figs. 116 and 139 ), apical incurved part shorter, 1 / 2.6 of the length of cercus, and wider; dorsal denticle much larger and nearer to the apical denticle; in posterior view dorsal denticle longer or weakly shorter than apical denticle], the shape of longer and slender ovipositor which is 10.7 mm in allotype [in P. bosphoricus bosphoricus , ovipositor ( Fig. 120 ) 7.5 mm, short and broad (high), 5.3 times longer than high and 1.6 times longer than pronotum; apical serrated part weakly and gradually upcurved and its outline rounded; basal fold of lower valve wide, its ventral margin almost triangularly expanded; ventral margin of ovipositor distinctly convex along its length], the shape of male pronotum [in P. bosphoricus bosphoricus , pronotum ( Fig. 114 ) more similar to the members of the P. similis group, slender, much less compressed and less constricted laterally; anterior margin of prozona and metazona much less raised and less widened; shoulder very weak], the shape of male subgenital plate [in P. bosphoricus bosphoricus , distal part of male subgenital plate ( Fig. 117 ) longer than proximal part; posterior incision distinctly deep and narrow, deeper than the width of incision], and body colouration [in P. bosphoricus bosphoricus , body ( Figs. 114, 115, 118, 119 ) almost unicolour green, with small black spots; metazona of male pronotum with 2 triangular red band on both sides in dorsal view; without black bands, stripes and much less dark markings on body surface in both sexes of the types and topotypes; this colouration is also more similar to the members of the P. similis group]. This new species relatively more similar to P. bosphoricus septemlacus ssp. nov. based on the shape of the pronotum. But, the pronotum less compressed laterally and less widened in metazona [in P. bosphoricus septemlacus ssp. nov. ( Figs. 124 , 131 ) pronotum very strongly compressed and widened in metazona]. Besides, the narrower fastigium of vertex, male cercus, subgenital plate and ovipositor, as in the nominotypical subspecies, are different (see also description, diagnosis and figures of Poecilimon bosphoricus septemlacus ssp. nov. above).

Material examined. Turkey: Kastamonu Prov., Tosya, Ilgaz Geçidi , 1650 m, 19.7.2002, 5 males (including holotype) , 7 females; Kastamonu Prov., Ilgaz Yolu, Kırık Köyü , 1180 m, 16.7.2002, 4 males, 7 females ; Kastamonu, Ilgaz Dağı , 2080 m, 17.7.2002, 1 male, 2 females (leg. M. Ünal ) ( AİBÜEM).

Etymology. The “Ilgaz” Mountain is the type locality of this new species.

Remarks. This new species was given as P. bosphoricus in Ünal (1999, 2003, 2010). I have been aware of the distinction of this species for a while.After examining the type material of P. bosphoricus in the NMW collection, its clear differences in both sexes have been revealed. All populations of this new species exhibit stable characteristics and can be easily distinguished from P. bosphoricus , as detailed in the description above. The previous records of P. bosphoricus from Bolu Province (except Yedigöller area, N of Bolu, see P. bosphoricus septemlacus ssp. nov. above) and from its eastern regions (Karabük, Çankırı, Kastamonu provinces) belong to this new species.
