Type material. Holotype: ♂ from Fazenda Experimental da UFAM, 02°38'55.8"S, 60°03'09.4"W, Manaus, Amazonas, Brazil, unknown date, E. P. Franken & A.C.K Silva leg. (MPEG 35025). Paratype: 1♀, same data as holotype (MPEG 35026).
Additional material examined. BRAZIL: Amazonas: 1♀ from Fazenda Experimental da UFAM, 02°38'55.8"S, 60°03'09.4"W, Manaus, unknown date, E.P. Franken & A.C.K Silva leg. (MPEG 34601).
Etymology. The specific epithet (to be treated as a noun in apposition) means a person who lives in Manaus (Brazil).
Diagnosis. Among all species of Amphidraus, the male of A. manauara sp. nov. is most similar to that of A. caxiuanan Salgado & Ruiz, 2017 by having the embolic disc with a long, prolaterally projected distal process (dPED) with rounded tip, and a short, ventrally projected ventral process (vPED) (Figs 15C, 17A, 18B); also by having the tibial apophyses with similar pattern (RvTA short and rounded and the RTA is curved on its basal portion and points to apex of cymbium; Figs 15D, 17C, 19G); and by having the cymbium with the proximal, dorso-prolateral portion prominent and one cavity placed on proximal, dorso-retrolateral portion (Figs 17B, 19D). However, the male of A. manauara sp. nov. can be distinguished by having the embolus shaft and embolic filament shorter in proportion to embolic disc (Figs 19A, 19C), by having shorter proximal, dorso-prolateral projection of cymbium (Figs 19B, 19D) and shorter RTA (Figs 19 E–G). The female of A. caxiuanan is unknown, but among Amphidraus females currently known, A. manaura sp nov. is most similar to A. complexus Zhang & Maddison, 2012 by having short copulatory ducts, and the copulatory openings far apart from the posterior border of the epigyne (Figs 16D, 17D); see Zhang & Maddison 2012: figs 5–6). However, the female of A. manauara sp. nov. can be distinguished by having glands associated with the copulatory openings, and longer copulatory ducts (Figs 16 C–D, 17D).
Description. Male holotype (MPEG 35025). Total length: 2.59. Carapace 1.37 long, 0.90 wide, 0.60 high. Ocular quadrangle 0.67 long. Anterior eye row 0.98 wide, posterior 0.84 wide. Legs 4312. Length of legs: I 2.03 (0.66 + 0.74 + 0.63); II 1.89 (0.60 + 0.67 + 0.62); III 2.29 (0.71 + 0.77 + 0.81); IV 2.61 (0.78 + 0.86 + 0.97). Palp (Figs 15 C–E, 17A–C, 19A–B, 19E): femur and patella with no modifications; cymbium oval (Figs 15E, 17B); tegulum with stout and straight lobe (Figs 15C, 17A); embolus shaft (e) with no modifications; embolic filament short, approximately 1/3 the length of embolus shaft (Fig. 17A). Color in alcohol (Figs 15 A–B): cephalic area black; thoracic area brown with pale longitudinal stripe; abdomen dorsally with two longitudinal brown lateral stripes and one longitudinal central pale stripe intersected by smaller pale stripes; ventrally pale; legs pale.
Description. Female paratype (MPEG 35026). Total length: 2.75. Carapace 1.34 long, 0.87 wide, 0.62 high. Ocular quadrangle 0.59 long. Anterior eye row 0.93 wide, posterior 0.85 wide. Legs 4321. Length of legs: I 1.94 (0.62 + 0.73 + 0.59); II 1.84 (0.59 + 0.65 + 0.60); III 2.27 (0.70 + 0.76 + 0.81); IV 2.60 (0.74 + 0.86 + 1.00). Epigyne (Figs 16 C–D, 17D): epigynal plate with a large, posterior dorsal pocket; copulatory openings separeted by approximately two diameters of the copulatory duct; short copulatory ducts connected to anterior, outer portion of spermathecae; rounded spermathecae with narrower terminal portion; fertilization ducts anteriorly placed and laterally projected; Color in alcohol (Figs 16 A–B): carapace as in male; abdomen dorsally brown with longitudinal pale stripe intersected by three pale stripes on posterior region; ventrally pale.
Distribution. Known only from the type locality (state of Amazonas, Brazil) (Fig. 20).
