Dorsal ray short, measuring 7-10 (av. 5, n=3), bifurcated in its posterior third; each branch divided additionally into two smaller branches (Fig. 2J). Genital cone well expressed, with two papillae (Fig. 2H). Spicules equal, with undivided tips, 211-240 (av. 222, n=12) long, with dense proximal end and pointed distal tip. Spicule alae transversely striated on medial surface (Fig. 2G). Gubernaculum lanceolate, 55-68 (av. 62.88, n=9) long (Fig. 21). Female: Body length 4.46-5.90 mm (av. 5.25 mm, n=12). Width at anterior end 24-26 (av. 25, n=12), maximum width 125-180 (av. 144, n=12). Cephalic vesicle measuring 50-55 x 32-38 (av. 52x34, n=9). Oesophagus 362-400 (av. 382, n=12) long. Nerve ring at 140-148 (av. 143, n=5) from anterior end. Excretory pore and deirids at 170-180 (av. 178, n=5) and 180-198 (av. 188, n=5), respectively (Fig. 2A). Vulva situated at 1.20-1.40 mm (av. 1.32 mm, n=12) from posterior body end. Vagina short, continuing into ovejector with well-developed sphincters. Total length of ovejector with sphincters 179-210 (av. 240, n=ll) (Fig. 2C). Eggs measuring 80-96 x 38-55 (av. 92x42.5, n=10). Tail conical, with truncated end, 44-57 (av. 53, n = 10) long, with one thin terminal spine 15-19 (av. 17, n=9) long and three rounded almost equal processes 10-14 (av. 12, n=9) long (Fig. 2B). Discussion: In their study on nematodes from the genus Molinostrongylus from Miniopterus schreibersi from Bulgaria, Yanchev and Stoykova (1973) refer them to Molinostrongylus ornatus Mönnig, 1927. However, the examination of the same specimens together with additionally collected materials from other geographic localities in this country, and the comparison with the data of Dollfus (1954), Durette-Desset and Chabaud (1975) and Tkatch and Sharpilo (1988) show that those nematodes are identical to Molinostrongylus panousei Dollfus, 1954. Their affiliation to this species is unequivocal because of their characteristic synlophe, similarity of morphometric characters, and because M. panousei parasitizes only M. schreibersi throughout its range in Europe. Molinostrongylus skrjabini Skarbilovitch, 1934 Host: Nyctalus noctula (Schreber) - 82.75%. Intensity of infection 1-354. Location: small intestine. Distribution in Bulgaria: Sofia region (the village of Ginzi, Sofia). Redescription (based on 10 male and 9 female specimens from Nyctalus noctula, Sofia): Small straight thin nematodes with transversely and longitudinally delicately striated cuticle. Cephalic vesicle symmetrical. Apically, triangular buccal orifice, 2 amphids, 6 labial and 4 cephalic papillae (Fig. 3C). Deirids posterior to nerve ring. Synlophe: In both sexes, two lateral cuticular alae measuring 7 high and 5 wide (n=4). Alae appear posterior to cephalic vesicle and gradually disappear posteriorly to vulva of females or at distance of about 170 from bursa of males. Ventral and dorsal body surfaces without cuticular ridges (Fig. 3B). Male: Body length 2.64-3.00 mm (av. 2.80 mm, n=10). Width at anterior end 10-11 (av. 10.5, n = 10), maximum width 55-60 (av. 56.8, n=10). Cephalic vesicle 20-24 x 17-20 (av. 21 x 18, n=6). Oesophagus cylindrical, 172-225 (av. 184, n=8) long. Nerve ring, excretory pore and deirids situated at 86-93 (av. 90, n=5), 110-120 (av. 115, n =4),
