Redescription. FEMALE (2 paratypes). Body, including gnathosoma, 320–335 long, 135–145 wide. Ventral projections of subcapitulum tongue-like, about 9 long, 9 wide. Propodonotal shield length 45–47, maximum width 35–38. Dorsal and ventral surface of hysterosoma finely and regularly striated. Setae si and f2 present, c2 absent. Distance se–se about 55–60. Punctate areas between setae h2 and h3 present. Sternum about 25 long, its posterior end not connected with apodemes II. Posterior projections of coxal fields I tongue-like, about 13 long, 12 wide. Distal ends of apodemes II connected with posterior apodemes of coxal fields II by sclerotized band. Posterior apodemes of coxal fields II distinctly developed, fused with epigynum. Apodemes III not fused with epigynum. Epigynum about 4 long, 13 wide. Setae 4b situated posterior to epigynum. Apodemes IV connected with sclerotized fields of oviporus by narrow and weakly sclerotized interrupted bands. Inseminatory canal about 18 long, opening terminal. Legs III–IV subequal in length, about 120 and 135 long, respectively. Trochanters I–II without ventral folds; trochanters III–IV with distinct transverse crests ventrally. Setal lengths: se 9–10, h2 180–185, 1a 8–9, 3a 11–12, vF I–II 50–55, cG I–II 7–8, mG I–II 25–30, d I–II about 15, d III–IV about 25.

Distal ends of apodemes II distinctly developed, connected with posterior apodemes of coxal fields II by sclerotized band. Posterior apodemes of coxal fields II distinctly developed, but separated from each other. Apodemes III and IV free. Pregenital apodeme 4 long, 22 wide. Setae 4b situated on pregenital apodeme. Aedeagus 30 long. Legs III–IV subequal in length, 105 and 125 long, respectively. Trochanters I–II without ventral folds; trochanters III–IV with distinct transverse crests ventrally.

Type material examined. Two female, 1 male, and 2 protonymph paratypes ( IRSNB) from Myotis myotis

(Borkhausen) ( Vespertilionidae ), BELGIUM: Wallonia Reg., Namur Prov., Grottes de Han cave , 50°08'N, 05°15'E, 15 January 1959, coll. A. Fain.

Type deposition. Holotype is deposited in IRSNB.

Non-type material examined. One female and 1 male ( IRSNB) from Histiotus velatus (Geoffroy) (Vespertilionidae) (0.6.29.1-3 BMNH), BRAZIL: Parana, Palmeira, coll. unknown; 1 male and 1 tritonymph ( IRSNB) from Myotis velifer (Allen) (Vespertilionidae) , USA: Oklahoma, Woodward Co., 20 October 1978, coll. unknown.

Host range and distribution. This species parasitizes different bats of the family Vespertilionidae in both the New and Old Words: Myotis myotis (type host) from Belgium, Nyctalus noctula (Schreber) from Switzerland, Otonycteris hemprichii Peters from Tunisia, Kerivoula smithi Thomas from the Democratic Republic of Congo, Myotis velifer (new host record) from USA (Oklahoma), Histiotus velatus from Brazil ( Fain 1959a,b, 1967; our data).
