Poecilimon bosphoricus septemlacus Ünal, ssp. nov.

( Figs. 122–134 )

Type locality. Turkey: Bolu Prov., Yedigöller, Tuzak Yayla , 1520 m .

Description. Male (Holotype). Fastigium of vertex only 1.5 times narrower than antennal scape, with a narrow and long dorsal fossa; rounded at apex (in holotype, left apical corner roundly crushed, probably during collecting); in some paratypes slightly wider. Pronotum ( Figs. 124 , 125 ) saddle shaped, strongly constricted; anterior half of prozona and metazona strongly raised (almost 45 degree) and the latter widened; metazona 1.9 times wider than compressed part of prozona; anterior margin slightly concave, posterior margin with a wide triangular indentation; shoulders very distinct, inflated; ventral margin of paranota slightly bent outwards in dorsal view. Tegmina ( Figs. 124 , 125 ) following metazona quite wide, slightly narrower than hind margin of metazona; reaching beyond half of second abdominal tergite. Hind femur without ventral spines. Supra anal plate simple, rounded, wider than long; in some paratypes as long as wide. Cercus ( Figs. 126, 127 ) stout as in the nominotypical subspecies, but larger, with 10–12 posterior denticles, including apical larger one, with a large dorsal denticle near apex which slightly shorter than apical denticle and which forms apex like a bifurcate in posterior view; apical fourth distinctly but not very strongly incurved. Subgenital plate ( Fig. 128 ) with long distal part, posterior margin wide and truncate, slightly concave; in some paratypes, posterior incision more triangular, but shallow.

Female (Allotype). Fastigium of vertex wider than that of male, 1.3 times narrower than scapus, with a short and distinct dorsal fossa, distinctly rounded at anterior margin. Pronotum ( Figs. 131, 132 ) saddle-shaped; prozona constricted laterally; anterior margin of prozona and metazona distinctly raised, which forms it a distinct concavity in lateral view; metazona slightly wider than prozona; anterior and posterior margins slightly concave in dorsal view. Tegmina very small, rounded, scale-like laterally. Hind femur without ventral spines. Supra anal plate 1.6 times wider than long, almost triangular, but posterior corner narrowly rounded. Cercus narrow, apical fourth slightly incurved, apex blunt. Subgenital plate ( Fig. 133 ) slightly wider than long, almost triangular, posterior corner narrowly rounded, with a triangular depression in the middle at the base. Ovipositor ( Fig. 134 ) stout and high in the mid part, 5.4 times longer than high and 1.7 times longer than pronotum, its ventral margin very weakly convex; its serrated apical part sharply upcurved and pointed at apex, with 6 upper and 8 lower apical teeth; in other females, upper valve with 6–8, lower valve with 8–12 apical teeth; basal fold of lower valve slightly widened and broadly rounded at ventral margin.

Colouration. In dry specimens, green colour replaced with creamish milky-brown. Body darkened with remarkable yellow, black and red marks, spots and stains. Face creamish milky brown. Antennae black with sparse (not very dense) creamish light rings. Dorsal surface of head with small black spots, occiput blackened. Pronotum typically with 3 transversal bands: anterior raised part of prozona yellow, remaining part of prozona black, and metazona reddish except the black posterior margin in both sexes, but the posterior part of prozona in female partly black with some creamish marks (in most females this part fully black); paranota at the beginning of metazona creamish with black spots. Tegmina yellow in both sexes, but the basal half (mostly under pronotum) in male blackened. All legs, including tibias with dense, rounded, black-brown spots; dorsal sides of tibias with a thin longitudinal brown stripe along their lengths; ventral sides of femora with 2 parallel longitudinal stripes along their lengths (partly on hind femora); outer and inner sides of hind femora with a longitudinal black band in the middle. Abdominal tergites (except first tergite) black with a thin light transversal stripe along posterior margin. First abdominal tergite yellow in both sexes. In lateral view, ventral half of abdomen also black, but gradually replaces with creamish brown downwards. Apical incurved part of male cercus black. Subgenital plates in both sexes pale yellowish cream. Ovipositor milky brown with small reddish spots; apical teeth black; its base with a black transversal band; basal part of ventral valve, its basal fold and ventral part of gonangulum darkened with reddish brown.

Discussion. This new subspecies has stout male cerci as in P. bosphorisus s. str. But it is separated from the nominotypical subspecies by the structure of pronotum in both sexes which is saddle shaped, anterior part of prozona and metazona strongly raised [in P. bosphorius bosphorius pronotum ( Figs. 114, 118 ) near to P. similis species group with much less raised anterior margin and metazona in both sexes, and much less widened metazona], the wider posterior margin of male subgenital plate with distinctly broader and shallower posterior incision [in P. bosphorius bosphorius ( Fig. 117 ) posterior margin narrow, clearly with a deep and narrow incision], the shape of ovipositor with sharply upcurved apical serrated part, the shape of the narrower basal fold of ovipositor with rounded ventral margin [in P. bosphorius bosphorius ovipositor ( Fig. 120 ) short and its serrated apical part gradually and less curved; the basal fold triangularly expanded], and the colouration with strongly blackened body with remarkable yellow and red parts [in P. bosphorius bosphorius , body ( Figs. 114, 115, 118, 119 ) almost unicolour green with small black spots in the type specimens and topotypes from İstanbul]. It is different from Poecilimon ilgazi sp. nov., which is the closest species to P. bosphoricus s. lat. by the wider fastigium of vertex (in Poecilimon ilgazi sp. nov. two times narrower than scapus, while 1.5 in this new subspecies), the strongly saddle shaped pronotum in both sexes, the stouter shape of male cercus [in Poecilimon ilgazi sp. nov. cercus ( Figs. 139, 141 ) much more slender, slightly incurved along its length], the shape of ovipositor which is shorter and higher [in Poecilimon ilgazi sp. nov. ovipositor ( Fig. 148 ) very long and narrow, serration part weakly or not widened], the basal fold of ovipositor roundly expanded ventrally (in Poecilimon ilgazi sp. nov. basal fold very narrow and very slightly convex or straight at ventral margin), and the blackened colouration (see also description and diagnosis of Poecilimon ilgazi sp. nov. below).

Measurements (mm). Holotype (male). Length of body 19; pronotum 4.5; tegmina visible 2.7; hind femur 13.8. Allotype (female). Length of body 19; pronotum 5.1; hind femur 14.9; ovipositor 8.7. Paratypes. Length of body: male 17.4–20.2, female 17.4–20.9; pronotum: male 4.2–5, female 4.7–5.2; tegmina visible: male 1.8–3.1; hind femur: male 12.5–13.4, female 13.8–14.6; ovipositor: 8.3-9.6.

Material examined. Turkey: Bolu Prov., Yedigöller, Tuzak Yayla , 1520 m, 24.6.2000, 11 males (including holotype), 11 females ; Bolu prov., Yedigöller Yolu, Yığılca KavŞağı , 20.7.1997, 4 males (leg. M. Ünal ) ( AİBÜEM) .

Etymology. In Latin, “septemlacus” means seven lakes (yedigöller in Turkish), which is the type locality of this new subspecies.

Remarks. This new subspecies was given as P. bosphoricus in Ünal (2003).
