Tephritis dilacerata kaszabi new subspecies

(Figs 2d; 11–12)

Type material: Holotype ♀: “ Mongolia, Central aimak, / Zuun-Chara, h= 850 m, / exped. Dr. Z. Kaszab, 1964”, Nr. 281, 8.07.1964” (HMNH).

Paratypes: Mongolia: Central aimak, Zuun-Chara, h= 1350 m, 8.07.1963, 1♂, 11♀ (Nr. 281, exped. Dr. Z. Kaszab, 1963); Central aimak, Zuun-Chara, h= 850 m, 8.07.1964, 15♂, 13♀ (Nr. 281, exped. Dr. Z. Kaszab 1964) (HMNH; SIZK).

Diagnosis. Tephritis dilacerata kaszabi is similar to the nominative subspecies differing by having the oviscape longer than 2.5 posteriormost tergites and aculeus 8 × as long as wide, longer than 1.1 mm ..

Description. Head, thorax, legs wings and abdomen (Figs 11a – d): as in T. dilacerata dilacerata.

Terminalia: Male. Epandrium and phallus similar to those in T. bardanae (Figs 10 e–f). Female. Oviscape as long as 3 last abdominal tergites. (Fig. 11d). Eversible membrane with 2 pairs of taeniae 0.35 × as long as membrane itself; with small scales on whole surface of the membrane. (Fig. 12c). Aculeus 8 × as long as wide, with widely rounded apex (Figs 12 a–b). 2 long and narrow, papillose spermathecae 6–7 × as long as wide (Fig. 12d).

Measurements: Female. BL= 4.8–5.8 mm (n=10); WL= 4–4.9 mm (n=10), C2= 1–1.2 mm (n=10); AL= 1.1– 1.35 mm (n=10); AL/C2=1.14–1.35 (n=10). Male. BL= 3.5–4.5 mm (n=10); WL= 3.8–4.3 mm (n=10).

Host plants. Unknown.

Remarks. We consider this geographically isolated population to belong to a separate subspecies readily differing by the longer ovipositor.
