Further specimens examined (not included in type series. The single male was collected from another locality and differs slightly): 1 Ƌ TR - Konya 1800m Alacabel Geçidi N37°10' E31°56' (NMBE).


Size (including rostrum): Holotype male: 9.1 mm, Paratypes: 7.6–9.1 mm. Habitus ( Figs 1A –B View Figures 1 ), body black.

Head large and wide; rostrum somewhat longer than wide, rostral dorsum flat and shiny, punctate-striolate; impressed behind V-shaped epistome; frons a little more than one third wider than rostral dorsum between insertions of antennae, with small, puncture-like fovea; scrobes short; rostrum at level of pterygia somewhat narrower than width of head at level of the eyes.

Antennae: Scape short and robust, weakly widening towards tip, of twice its width at apex; first and second funicular segments of same length, 1.2 times longer than wide; third to seventh globular to weakly transverse, club fusiform.

Pronotum transverse (length/width: 0.76–0.8), widest just before midlength, laterally strongly rounded, hind margin wider than anterior one. Surface shining, without microsculpture, covered with coarse, partly umbilicate tubercles, at disc tubercles partly coalescent; at discal area scarce punctures inbetween; sparse, short bowed brownish bristles arise from umbilicate tubercles at sides of pronotum.

Elytra (length/width males: 1.44–1.49; females: 1.27–1.32) oval, widest in the middle, without shoulders and laterally regularly rounded towards base. Striae with shallow but pronounced regular punctures, from which tiny, hardly visible bowed bristles arise. Intervals more (males) or less (females) rugose with dense and irregularly arranged fine punctures, from which short and bowed, mainly brownish bristles arise (best visible at elytral declivity). Outer intervals with rasp-like punctures appearing as pointed microscopic tubercles.

Legs very robust, even more robust in males, protibiae not dilated outwards, male hind tibiae weakly incised, apex thorn-like prolonged; tarsi very robust.

Genitalia: penis parallel-sided from basal third up to apex, apex subtruncate, faintly rounded; laterally bowed in basal half ( Figs 2A –B View Figures 2 ). transfer apparatus consisting of four twisted sclerites ( Fig. 2C View Figures 2 ). Female sternite VIII very robust and entirely strongly sclerotized, plate roundish, laterally strongly rounded, apical margin straight and set with long hairs ( Fig. 2D View Figures 2 ). Spermatheca with c-shaped and regularly tapered cornu, and short globular nodulus and ramus ( Fig. 2E View Figures 2 ). Ovipositor rather simple, very robust and strongly sclerotized, torpedoshaped ( Fig. 2F View Figures 2 ). Apex inconspicuous (without long styli nor bristles), apical half with numerous sensorial grooves.

Sexual dimorphism: Males differ from females in: elytra narrower; surface of elytra more rugose; legs stronger: femora thicker, tibiae stronger, meso- and metatibiae stronger mucronate, metatibiae weakly incised; tarsi – especially third bilobed segment and strongest pronounced in protibiae – broader, almost twice as wide ( Figs 1A –B View Figures 1 ).

Differential diagnosis: Otiorhynchus gultekini   sp. nov. belongs to the species with pronounced elytral striae, and with flattened tubercles on the pronotum. It is morphologically close to O. ikisderensis   and O. riedeli   . Based on the shape of the penis, especially the broadly truncated apex, the new species also shows similarities with O. karagolensis   .

Derivation of name: The new species is named after my esteemed Anatolian colleague Dr. Levent Gültekin, expert in Lixinae   , of the genus Larinus Dejean, 1821   .

Ecology: The new species was collected together with similar black and shiny Carabidae   under stones on Alpine meadows from 1800–2600 m a.s.l.
