( Figures 1–2 )

Type locality. Türkiye, Sinop, around Boyabat , 41° 33’ 57.6” N 34° 48’ 51.3” E, 510 m.

Type material. Holotype: ♂, Türkiye, Sinop, around Boyabat , 41° 33’ 57.6” N 34° 48’ 51.3” E, 510m., leg. R. Tanyeri and Ü. Zeybekoğlu, Tshurtshurnella sinopei sp.n .; Paratypes: 8 ♂♂, 5♀♀, Türkiye, Sinop, around Boyabat , 41° 33’ 57.6” N 34° 48’ 51.3” E, 12/08/2017, leg. R. Tanyeri and Ü. Zeybekoğlu (Type material is housed in Ondokuz Mayıs University, Entomology Laboratory) .

Description. The body is short and blunt; metope is long, with median carina visible; sublateral carinae are weak and there are oval yellow spots between the median carina and sublateral carinae ( Figure 1e ). The anterior margin and lateral margins of the metope are slightly curved; the rostrum reaches hind coxae. Pedicel sphaerical. Coryphe transverse, side angle at the front, width is twice its length, trace of median carina; anterior margin slightly curved. No ocelli. Pronotum twice as wide as long medially, same length with coryphe, median carina visible, anterior margin curved, and posterior margin straight. The lengths of coryphe, pronotum and mesonotum are approximately equal to each other. Fore wings cover the abdomen totally, without hypocostal plate. Hind tibia with two lateral spines. First metatarsomer with one intermediate spine.

Coloration. General coloration light yellow, transversal dark brown bands on posterior 2/3 of fore wings ( Figure 1 a–f). Pedicel, flagellum, rostrum and spines on legs are dark brown. Abdomen is straw yellow.

Body length. ♂♂ 3–3,2 mm; ♀♀ 3,2–3,5 mm. The measurements of the body parts are given in Table 1 .

Male genitalia. Phallobase straight, tubular, with two pairs of equal sized spines dorsally. The first pair of spines is on the tip of aedeagus, the other pair are on the ¾ part of the aedeagus ( Figure 2a ). Dorsolateral lobes of audial sheath are wide and its margins have tooth in the shape of saw ( Figure 2a, b ). There are strong, hook shaped, two long spines with an outward facing tip on these lobes ( Figure 2b ). Ventral lobe of aedeagal sheath narrows, reaching phallotrema. Stylus is narrow at the tip, wide at the basal, dorsal margin is ovalish, ventral margin is wavy ( Figure 2d ). Anal tube is oval, narrows to the tip, in the middle part its width is about half of its length ( Figure 2e ).

Female genitalia. Anterior margin of pregenital sternite VII is concave and slightly protruding at median. Posterior margin is convex ( Figure 2g ). Female anal tube is narrow at the basal and elliptical towards the tip ( Figure 2f ).

Habitat. The materials were collected from the open area with Graminae and Compositae samples in the undergrowth of the mixed forest area.

Diagnosis. Tshurtshurnella sinopei sp. nov. closely resembles T. yozgatica Kartal, 1985 and T. curtulum Gnezdilov et Oezgen, 2018 by its genital characters. However, while there are two pairs of spines at the dorsal margin of T. sinopei sp. nov., there is one pair of spines at the dorsal of aedeagus in T. yozgatica ( Kartal 1985). Although T. sinopei sp. nov. resembles T. curtulum for having two pairs of spines at the dorsal margin, it is different from this species for dorsolateral margins of aedeagal sheat having saw-tooth and the tip of male anal tube not being pointed. In T. curtulum, dorsolateral margin of aedeagal sheath is straight and not saw toothed and the tip of male anal tube is not wide, it is visibly pointed ( Gnezdilov & Özgen 2018, fig. 30).

Etymology. The name was given with reference to the old name of the city of Sinop ( Turkey), where the samples were collected.
