Description. Adult. Coloration ( Figs 1–3 View Figs 1–7 , 11–13 View Figs 8–13 ). General coloration light yellow. Metope with 4 large glossy black spots on sides of median carina. Each gena with small black spot above metopoclypeal suture. One large black spot between lateral margin (keel) of metope and pedicel on each side of head below eye. Postclypeus with a pair of black lateral spots below metopoclypeal suture. Coryphe with a pair of large glossy black spots on sides of median carina. Fore wings with light costal margin and apical cells dark brown. Apices of spines on legs black.
External morphology. Metope wide, convex, with distinct but smoothed median and very weak sublateral carinae, all joined at one point apically on metopial upper margin ( Figs 3 View Figs 1–7 , 13 View Figs 8–13 ). Metopoclypeal suture distinct, strongly convex. Ocelli absent. Pedicel elongate, cylindrical. Coryphe transverse, 3 times wider than long medially, with median carina, anterior margin widely convex, posterior margin obtusely angulately concave ( Figs 1 View Figs 1–7 , 11 View Figs 8–13 ). Pronotum without carinae, as long as coryphe medially. Paradiscal fields of pronotum narrow behind eyes. Paranotal lobes of pronotum wide, without carinae. Mesonotum longer than pronotum, with median and lateral carinae. Tegulae small. Fore wings elongate, narrowing apically, with wide subcostal area proximally ( Fig. 2 View Figs 1–7 ), without hypocostal plate. Basal cell narrow. ScP+R(+MA) furcating into RA and RP; MP 2-branched; CuA simple (R 2 M 2 CuA 1). Radius furcates near basal cell, median near middle of wing. Hind wings rudimentary. Hind tibia with 2 lateral spines distally. First metatarsomere with 2 lateral and 2 intermediate spines apically.
Male genitalia ( Figs 14–19 View Figs 14–19 ). Hind margin of pygofer slightly convex (in lateral view; Fig. 14 View Figs 14–19 ). Anal tube elongate, weakly narrowing apically, truncate (in dorsal view; Fig. 15 View Figs 14–19 ). Anal column (epiproct) long, 0.3 times as long as whole tube. Apical processes of aedeagus enlarged, well visible above phallobase ( Figs 16–17 View Figs 14–19 ). Dorso-lateral phallobase lobes with marginal teeth dorsally ( Fig. 16 View Figs 14–19 ). Ventral phallobase lobe wide, narrowing apically, reaching almost half of penis length ( Fig. 17 View Figs 14–19 ). Phallotrema with concave ventral margin. Style massive, with hind margin straight and caudo-dorsal angle widely rounded ( Fig. 18 View Figs 14–19 ). Capitulum of style without neck (in lateral view; Fig. 18 View Figs 14–19 ), narrowing apically (in dorsal view; Fig. 19 View Figs 14–19 ), with large lateral tooth and distinct apical tooth.
Female genitalia. Hind margin of sternum VII widely concave. Anal tube twice as long as wide, rounded apically (in dorsal view). Anal column long, 0.3 times as long as whole tube.
Total body length. Males: 3.7–4.4 mm, females: 4.0– 4.7 mm.
Fifth instar nymph ( Figs 20–22 View Figs 20–22 ). Coloration ( Figs 7–10 View Figs 1–7 View Figs 8–13 ). Metope with 4 large black spots – 2 separate spots in its upper part and 2 joined spots above clypeus. One black spot between lateral margin (keel) of metope and pedicel on each side of head. Postclypeus with 2 lateral black spots. Each paranotal lobe with large black spot. Coryphe with a pair of black spots. Apex of rostrum, tarsomeres of fore and middle legs, and third tarsomere of hind legs dark brown. Two wide longitudinal dark brown or black stripes extending through pronotum, mesonotum, metanotum, and abdomen. Another wide longitudinal dark brown or black stripe extending from paradiscal field of pronotum through wing pad and abdomen on each side of body. One more dark brown stripe extending through wing pad near its costal margin on each side of body. Fore and middle femora and tibiae with dark brown longitudinal stripes. Abdominal laterotergites dark brown or black.
External morphology. Metope with median and sublateral carinae joined below its upper margin ( Fig. 21 View Figs 20–22 ). Metope with 19–20 sensory pits in 2 rows between lateral margins (keels) and sublateral carinae on each side ( Fig. 21 View Figs 20–22 ). Coryphe with tiny median carina, anterior margin obtusely angulate, lateral margins parallel to each other, posterior margin concave. Pronotum with tiny median carina. In every discal-paradiscal group of pronotum 18 pits arranged in 3 rows, in every paranotal group 6 pits arranged in 2 rows (2 + 4) on each side ( Fig. 20 View Figs 20–22 ). Mesonotum with tiny median carina and raised lateral carinae, every median paradiscal group with 5–6 pits on each side. Metanotum with tiny median carina and weak lateral carinae reaching only middle of segment, every median paradiscal group with 3 pits on each side. Forewing pads reaching anterior half of abdominal tergite III. Each forewing pad with 3 sensory pits. Tergite III with 3 lateral pits, tergite IV with 4–5 pits, tergites V–VII with 5 lateral pits, tergite VIII with 3–4 lateral pits, and tergite IX with a single pit on each side ( Figs 20, 22 View Figs 20–22 ). Abdominal segment VII without wax-pore plates. Abdominal segment VIII with two wax-pore plates. Hind tibia with 2 lateral spines distally and 8–10 apical spines. First metatarsomere with 2 lateral and 2 intermediate spines apically.
Total body length. 2.2–3.0 mm.
Differential diagnosis. According to the head coloration pattern (arrangement of spots) and also the structure of the male genitalia, the new species is closely related to Tshurtshurnella lodosi Dlabola, 1979 described from southeastern Turkey ( DLABOLA 1979). The differences between these two species are summarized in the key couplet below. The dark spot pattern clearly distinguishes T. decempunctata sp. nov. and T. lodosi from the other species of the genus. The new species also differs from the other Tshurtshurnella spp. in the presence of two intermediate apical spines on the first metatarsomere instead of one single spine, which is the characteristic feature of the other species ( GNEZDILOV 2003).
Etymology. From the Latin adjective decempunctatus (= ten-spotted), referring to the number of 10 large spots on the head of adult.
Ecology. The new species was collected on herbs in an oak ( Quercus ) forest ( Fig. 23 View Fig ).
