Redescription. FEMALE (2 paratypes). Body, including gnathosoma, 395–400 long, 205–210 wide. Ventral projections of subcapitulum short, about 4 long, 23 wide. Propodonotal shield length 50–53, maximum width 65–67. Dorsal and ventral surface of hysterosoma finely and regularly striated. Setae si, c2, and f2 present, setae c2 situated ventrally. Distance se–se 110–115. Punctate areas between setal bases h2 and h3 absent. Sternum about 35 long, its posterior apex connected with apodemes II by weakly sclerotized transverse band. Posterior projections of coxal fields I short, about 4 long, 18 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 7 long, 23 wide. Setae 4b situated posterior to epigynum. Apodemes IV fused 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 130 long. Trochanters I–II without ventral folds; trochanters III–IV with weakly developed, bracket-like ventral folds. Setal lengths: se 16–18, h2 170–180, 1a 9–10, 3a 11–12, vF I–II 65–67, cG I– II 11–12, mG I 60–63, mG II 50–55, d I–II about 45, d III–IV about 55.

MALE (2 paratypes). Body, including gnathosoma, 360–370 long, 180–185 wide. Ventral projections of subcapitulum short, about 4 long, 23 wide. Propodonotal shield length 45–47, maximum width 60–65. Dorsal and ventral surface of hysterosoma finely and regularly striated. Setae si, c2, and f2 present, seta ps2 present on one side of one of two specimens examined, setae c2 situated ventrally. Distance se–se 88. Punctate areas between setal bases h2 and h3 absent. Sternum 30 long, its apex connected with apodemes II by sclerotized transverse band. Posterior projections of coxal fields I short, about 4 long, 13 wide. Distal ends of apodemes II distinctly developed, connected with posterior apodemes of coxal fields II by interrupted sclerotized band. Posterior apodemes of coxal fields II distinctly developed, separated from each other. Apodemes III and IV free. Pregenital apodeme about 8 long, 25 wide. Setae 4b situated on pregenital apodeme. Aedeagus about 60 long. Legs III–IV subequal in length, 130–137 long. Trochanters I–II without ventral folds; trochanters III–IV with weakly developed, bracket-like ventral folds. Setal lengths: se 14–15, 1a 9–10, 3a 11–12, h2 115–125, vF I–II about 60, cG I–II about 13, mG I 60, mG II 55, d I–II about 50, d III–IV about 55.

Type material examined. Two female, 2 tritonymph, and 1 larva paratypes ( IRSNB) from Lavia frons (Geoffroy) (Megadermatidae) , RWANDA: Akanyaru river (Kanyaru), 02°04'32"S, 30°01'04"E, November 1955, coll. A. Fain; 2 male paratypes ( IRSNB) from same host,?Akan [locality in tropical Africa, probably Rwanda or the Democratic Republic of Congo], 24 February 1956, coll. A. Fain.

Type deposition. Holotype is deposited in MRAC.

Host range and distribution. This species parasitizes Lavia frons (type host) from Rwanda ( Fain 1956). Other chiropterans originally recorded as hosts of this species ( Fain 1959a, b) are actually hosts for other species of the genus Rodhainyssus (Fain 1967) .
