Rodhainyssus nycteris Fain 1967: 14 , figs. 4–6.

Redescription. FEMALE (2 paratypes). Body, including gnathosoma, 320–360 long, 145–150 wide. Ventral projections of subcapitulum tongue-like, about 9 long, 11 wide. Propodonotal shield length 45–50, maximum width 50–53. Dorsal and ventral surface of hysterosoma distinctly striated. Setae si, c2, and f2 absent. Distance se–se 79–84. Punctate areas between setae h2 and h3 present. Sternum about 22 long, its apex connected with apodemes II by weakly sclerotized transverse band. Posterior projections of coxal fields I tongue-like, about 9 long, 15 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, 18 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 dorsal. Legs III–IV subequal in length, about 110 long. Trochanters I–II without ventral folds; trochanters III–IV with distinct, square bracket-like ventral folds. Setal lengths: se 17–18, 1a 7–8, 3a 8–9, h2 175–180, vF I–II 50–55, cG I–II 8–9, mG I–IV 25–30, d I–IV about 25.

MALE (2 paratypes). Body, including gnathosoma, 270–280 long, 120–125 wide. Ventral projections of subcapitulum, widened, about 5 long, 15 wide. Propodonotal shield length 47–49, maximum width 55–57. Dorsal and ventral surface of hysterosoma finely and regularly striated. Setae si, c2, and f2 absent, setae ps2 present or absent. Distance se–se 80–83. Punctate areas between setae h2 and h3 present. Sternum 23 long, its apex connected with apodemes II by sclerotized transverse band. Posterior projections of coxal fields I present, tongue-like, about 9 long, 15 wide. 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 about 4 long, 18 wide. Setae 4b situated on pregenital apodeme or flanking it. Aedeagus about 35 long. Legs III–IV subequal in length, about 110 long. Trochanters I–II without ventral folds; trochanters III–IV with distinct, square bracket-like ventral folds. Setal lengths: se 9–10, h2 120–125, 1a 7–8, 3a 7–8, vF I–II about 40, cG I–II 8–9, mG I–II 25, d I–IV about 25.

Type material examined. One tritonymph, 1 protonymph, and 1 larva paratypes ( IRSNB) from Nycteris sp. ( Nycteridae ), RWANDA: Butare (Astrida), 02°35'50"S, 29°44'20"E, October 1955, coll. A. Fain ; 2 female, 3 male and 1 tritonymph paratypes ( IRSNB) from same host,? Ada [a locality in tropical Africa, probably, Rwanda or the Democratic Republic of Congo], October 1955, coll. A. Fain.

Type deposition. Holotype is deposited in MRAC.

Host range and distribution. This species parasitizes unknown species of the genus Nycteris in Tropical Africa (Fain 1967).
