IX. 81, Löbl et Smetana leg. (No. 23 "forêt de chênes, tamisage de bois pourri et de feuilles mortes") (MHNG). Description — Maie. Total body length 1.55-1.93 mm. General colour dark brown with sparse bronze tomentum, subshining. Frons and all other parts of head dark brown, almost black, sparsely tomentose and rather shining; M-shaped mark not visible. Cephalic chaetotaxy: bristles rather robust; pvt absent; 1 longer posterior and 1 short anterior ors; 3 ifr, anterior short, middle long and thick, posterior very short and thin. Eyes not reduced, their longest diameter about 2.4-2.6 times as long as smallest genal height. Antennae ochreous to pale brown, particularly apex of 1st flagellomere darkened; pedicel not longer than 1st flagellomere; arista 2.45 times as long as antenna. Thorax dark brown, mesonotum subshining, pleurae dull. Thoracic chaetotaxy: 1 dc, 6-8 rows of ac microsetae. Scutellum large, its length about 0.6 times its width; apical sc only slightly longer than lateral sc, the latter being as long as scutellum. Only 1 stpl but disc of sternopleuron with 2-3 short setulae in addition. Legs ochreous or yellowish brown (including cx^); t

% chaetotaxy as in Figs 55, 56, ventrally without a row of spines but with a mid ventral seta and rather long va. The ratio t

2 : mt

2 = 1.71. Wings polymorphic (Figs 47, 48) light brown, veins ochreous to light brown (C distinctly brown). R2+3 and R4+5 sinuate, the latter curving to C apically. Discal cell closed or open (in f. brach.) without tp. Ml +2 with a long but colourless fold beyond tp, M3 +4 with a short, brown extension. Wing measurements : length 0.66-1.14 mm, width 0.23-0.47 mm, C-index =0.70-1.25, ta-tp : tp = 1.90 (f. macropt.). Haltères yellow with ochreous knob. Abdomen subcylindrical, blackish brown, more shining than mesonotum. Sterna wide, nearly meeting terga laterally. S5 (Fig. 49) simple, wide, dark, sparsely setulose. S6 with a very short, membraneous, finely haired stripe beyond its ventral slender part. Genitalia — Periandrium (Fig. 50) rounded, long setulose ; its anal fissure larger than in P. icaros. Subanal plate small; caudal hair-like seta rather long but paired ventral setae reduced, thin. Gonostylus (Fig. 52) with large, flat, pale, anteriorly rounded fore lobe and narrow, backwardly tapered posterior lobe terminated into a robust inwardly curved spine. Aedeagal complex (Fig. 51) with dark, robust phallophore with rounded ventral apex. Distiphallus with short dorsal sclerite with a double triangular process; its ventral sclerite complex and prolonged to apex of distiphallus where it bears a group of dark tubercles. Postgonite short, somewhat bent, pale, with 3 setulae at anterior margin and a minute tooth on apex. Ejaculatory apodeme well developed. ~" Female — Total body length 1.52-2.38 mm; t

Abdomen flattened, with large terga and wide sterna, both almost meeting laterally. Postabdomen (Figs 53, 54) with dark and large S6 and 776. T7 shortened (but less than that of P. icaros) and pale pigmented. T10 transverse, very pale, with a pair of dorsal setae. S7 short, relatively lightly pigmented. S8 rounded trapezoidal but not long. S

10 somewhat wider than S8, anteriorly deeply and broadly emarginate. Spectacles-shaped sclerite (Fig. 58) with simply pigmented medial part, comparatively small rings, and strongly thickened basal parts of spermathecal ducts (the duct to single spermatheca much thicker). Spermathecae (Fig. 57) simply ball-shaped to oval, with
