pvt, very long occe, occl, long and very thick vte, vti, oc normal, posterior ors very thick and rather long, anterior ors short and much thinner. Four^pairs of if: anterior and hind most pairs short and thin, second pair very thick and cruciate, third pair longer than anterior ors. Face with moderately strong facial ridge, mouth edge somewhat protruding. Mesonotum yellow with brown hue in sagittal line and on anterior part. Pleura mainly yellow, only posterior half of mesopleuron and upper part of pteropleuron brown. Scutellum brown except for a narrow anterior band. Thoracic chaetotaxy: 1 h, 2 np, 1 prst, 2 sa, 1 pa, 1 strong prescutellar dc and three pairs of short anterior postsutural dc shortening anteriorad, 1 thin prsc, 2 se pairs of bristles. 8 acmi rows, no enlarged acmi. One very strong and thick posterior and one very short and thin anterior st. Wing length of holotype female: 1.63 mm, width: 0.71 mm. Wings yellowish, also veins yellow. Costa extending distinctly (about 0.05 mm) beyond conjointment with slightly upcurving r4 + 5. mg^ with 6 pairs of moderately strong bristles. c x = 1.20; t at only l5 times longer than t_. Alula short and narrow with slightly rounded apex. Haltères waxy yellow. Legs yellow, only mid coxae brown and dorsal part of femora yellowish brown. Firts femora with ad and av rows of moderately strong bristles. Mid femora with a thick and long, ventrally directed anteral subapical bristle, and four shorter and thinner bristles more basally up to apical 2/5 of femur. Dorsal half of mid tibia with a short pair of bristles, each at 1/5 and 13/20, a strong pair of bristles at 3/10, a very long and thick pair near its 3/4, and one short bristle at 1/10. One small ventral bristle at 5/8, long and very thick ventral preapical. Mid metatarsus with a very thick and long bristle (nearly as long as preapical on tibia) at basal 5/22. Abdomen ochreous yellow, brown only on hind margin of tergites and sternites. Cerci short and flat with minute hairs only. Body length of holotype female:. 1.81 mm. Holotype female: Tunisia, Boughrara, on MV light in agricultural college, 4 April, 1977, leg. DEBRECZY, EMBEY-ISZTIN, GOZMÁNY et MAHUNKA (No. 64). Leptocera (Opacifrons) tunisica sp.n. is an easily recognizable species. In the subgenus Opacifrons^TJuda^there are only three other species known from the Palearctic Region (flavilabris Hackm., s ep t en t r i ona 1 i s Stenh., ochrea L. Papp) with a ventral preapical bristle on mid tibia and a ventral bristle on mid metatarsus at the same time. In contrast to the former two species, the body of this new species is yellow, Its eyes smaller, it has 1 strong and 3 short pairs of postsutural dc bristles, the female has no spines or strong bristles on the cerci, only minute hairs. Its nearest relative is ochrea L. Papp, 1974 (Mongolia, South Gobi), but tunisica sp. n. has not two but three short dc pairs before the robust hind dc pair, and the anterior dc pairs are distinctly shorter than on ochrea. Its c x value is lower and its body is bigger (1.81 mm) than that of ochrea (1.3-1.47 mm). L. (Rachispoda) fuscipennis (Haliday, 1833) - 1 d* (No. 49), 6 (?, 8 î (No. 56), 7 cf, 7 ? (No. 60), 1 V (No. 64), 1 ? (No. 77), 23 o", 16 ? (No. 80), 4 <?, 10 ? (No. 116), 1 cf (No. 117). A halophilous species. L. (Rachispoda) gel L. Papp, 1978 - 1 o* (No. 12). Described from Afghanistan; new to Tunisia. L. (Rachispoda) lutosoidea (Duda, 1938) - Id", 2 ? (No. 56), 12 d 1 , 14 ? (No. 60). Distribution: Europe, Canary Islands, Afghanistan. New to Tunisia. L. (Rachispoda) kabuli L.Papp, 1978 - 9 o*, 8 ? (No, 56). \t is resembles more fuscipennis Hal. than mode sta (Duda, 1924), since kabuli has one median row of acmi, agreeing with fuscipennis . But the arista of kabuli is three times longer than the antenna (not only two times as in fuscipennis) , the scutellar armature and genital structures are completely different (see PAPP 1978a: Fig, 11, 12, 14, 15, 26). In our CoRection there are six specimens identified by O. DUDA as " oelandica Stenh.". There are three specimens of fuscipennis Hal. among them: 1 6: Sfax, BIRÓ - 7. n 1903 - "Limosina oelandica Stenh." det. BECKER, "oelandica d" det. O. DUDA; 1 6: Tunis, Hoegen - " oelandica d" det. O. DUDA; 1 ?: Sousse, BIRO -^28.n. 1903. - " oelandica ?" det. O.DUDA. Specimens of kabuli L. Papp: 1 d", 1 ?: Gafsa, BIRO* - 22. ni. 1903. - " oelandica d 1 /?" det. O. DUDA; 1 6: Tunisia, Djedeida -1913. V. 31. - "oelandica d 1 " det. O. DUDA. L./O./ kabuli L. Papp was described from Afghanistan; new to Tunisia. L. (Rachisopda) modesta (Duda, 1924) - 1 ? (No. 56). New to Tunisia. L. (Rachispoda) varicornis (Stróbl, 1900) - 4 o", 6 ? (No. 56), 27 ó", 45 ? (No. 60), 1 6 (No. 106). Widespread in the Palaearctic and Ethiopian Regions. New to Tunisia. L. (Leptocera) curvinervis (Stenhammar, 1854) - id, 2 9 (No. 56), 1 d (No. 97), 1 o", 1 ? (No. 117). An almost cosmopolitan species, developing in all kinds of ;nud.
