e s : body length 10.10-14.60 mm, maximum width 0.10 mm. Esophagus length 3.906.80 mm. Vulva situated at 4.00-7.00 mm from anterior end. Length of vulvar flap 0.096 mm (Fig.6c). Tail tip rounded, anus situated subterminally

. Barrel-shaped eggs 0.055-0.057 x 0.032-0.034 mm. Male s : body length 9.60-10.60 mm, maximum width 0.05 mm. Esophagus length 3.20-3.70 mm. Spicule length 1.35 mm. Differential diagnosis: Papers by SKRJABIN et al. (1957), and SKVORCOV (1971a,b),were reviewed in the study of the present species. None of males of the already known species of bat-infesting Capillaria bears the typical, ventrally extended lobe in the posterior end of the body as described in the new species. C. palmata Chandler, 1938, and C. nycticeiusi Agrawal

, 1965, have a similarly long spicule; however, the shape of the tail end, including bursa and rays, is different. C. speciosa (Bened., 1873) has a spicular length three times longer than that of C. vietnamensis sp.n. On the contrary, C

. p int o i Freitas, 1934, C. Italica Ricci, 1949, C. rara Ricci, 1949, and C. rivarolai Lent, Preitas et Proenca, 1946, have a spicula three times smaller than that described in the new species. The comparison in not possible with the insufficiently described C_. diesingi (Kolenati, I856). The differences in the geographical distributions (

C. diesingi is known from Europe), however, make the taxonomic difference highly probable. C. vespertilionis (Rud., I8I9) has no original description, and therefore.according to TRAVASSOS, it is a nomen nudum, while LOPEZ-NEYRA places it with C. speciosa (Skrjabin et al., 1957). The male of C • pi- pistrelli Yamaguti, 1941, is not known. Polotype and paratypes: register No. V/8, deposited in the Parasitological Collection of the Hungarian Natural History Museum, Budapest.
