description: 12. Rodhainyssus saccopteryx Bochkov et OConnor sp. nov.   
(Fig. 29)  
 Description. FEMALE (holotype). Body, including gnathosoma, 305 long, 115 wide. Ventral projections of subcapitulum distinctly developed, sword-like, 15 long, 5 wide. Propodonotal shield length 50, maximum width 45. Dorsal and ventral surface of hysterosoma striated with interrupted lines. Setae si present, c2 and f2 absent. Distance se–se 65. Punctate areas between setae h2 and h3 present. Sternum 30 long, its apex joining but not completely connected with apodemes II. Posterior projections of coxal fields I distinctly developed, 11 long, 22 wide. Distal ends of apodemes II fused to each other and forming short posterior projection, 12 long. Posterior apodemes of coxal fields II short, not fused with epigynum. Apodemes III consisting of 2 parts, their distal parts completely fused with epigynum. Setae 4b situated posterior to epigynum. Apodemes IV connected with sclerotized fields of oviporus by narrow and weakly sclerotized interrupted bands. Inseminatory canal 18 long, opening terminal. Legs III–IV subequal in length, about 115 long. Trochanters I–II without folds; trochanters III–IV with distinct transverse crests ventrally. Setal lengths: se 9, h2 135, 1a 7, 3a 13, vF I– II about 25, cG I–II about 7, mG I–II about 22, d I–IV about 12.   
 MALE (paratype). Body, including gnathosoma, 245 long, 115 wide. Ventral projections of subcapitulum sword-like, 13 long, 4 wide. Propodonotal shield 45 long, 45 wide. Dorsal and ventral surface of hysterosoma striated by interrupted lines. Setae si present, c2, ps2 and f2 absent. Distance se–se 60. Sternum 33 long, its apex jointing but not connected with apodemes II. Posterior projections of coxal fields I distinctly widened, 10 long, 20 wide. Distal ends of apodemes II not connected with posterior apodemes of coxal fields II. Posterior apodemes of coxal fields II not fused to each other or with pregenital apodeme. Apodemes III fused to each other. Pregenital apodeme arch-like, 3 long, 27 wide. Setae 4b situated on pregenital apodeme. Aedeagus 45 long. Legs III–IV subequal in length, about 105 long. Small arch-like opisthogastric plate bearing setae h3 and ps3 present. Trochanters I–II without ventral folds; trochanters III–IV with distinct transverse crests ventrally. Setal lengths: se 10, h2 110, 1a 8, 3a 12, vF I–II about 15, cG I–II about 5, mG I–II about 12, d I–II about 9, d III–IV about 6.   
 Type material examined. Female holotype (BMOC 02-0918 - 089, 1) and male paratype (BMOC 02- 0918 - 089, 2) from Saccopteryx bilineata (Temminck) (Emballonuridae) (FMNH 177490), PERU: Madre de Dios, Manu, Maskoitania, 13.4 km NNW Atalaya, 12°46'18"S, 71°23'08"W, 480 m, 26 September 2001, coll. E. Suazo (ESG 063).   
 Type deposition. Holotype and paratype are deposited in UMSM.   
 Host range and distribution. This species is known from the type host Saccopteryx bilineata from Peru (our data).   
 Remarks. This new species differs from all known representatives of the genus Rodhainyssus in both sexes by the long sword-like posterior projections of the gnathosoma. In all other species these projections are widely rounded apically or are short. The new species is close to R. balantiopteryx and R. emballonurae. In all three species, setae c2 are absent, the sternum is not connected with apodemes II, apodemes III are fused to each other, and the posterior apodemes of coxal fields II are not connected with apodemes II. It differs from R. balantiopteryx in both sexes by the presence of setae si and by the absence of setae f2; in females by the presence of the punctate area between setae h2 and h3; in males by the presence of the median opisthogastric plate (fused adanal shields), and by setae 4b situated posterior to the pregenital apodeme. In both sexes of R. balantiopteryx setae si are absent, and setae f2 are present; in females the area between setae h2 and h3 are smooth; in males the median opisthogastric plate is absent, and setae 4b are situated on the pregenital apodeme. Males of R. saccopteryx sp. nov. differ from R. emballonurae by the arch-like shape of the median opisthogastric plate, bearing setae h3 and ps3, the absence of the ventral folds on trochanters I and II, and by the posterior end of the aedeagus situated distinctly posterior to setae g. In males of R. emballonurae the median opisthogastric shield has irregular margins and bears only setae ps3, its shape is close to ovoid in outline, the ventral folds of trochanters I and II are present, and the posterior end of the aedeagus is situated at the level of setae g.
