Amphidraus janauari   sp. nov.

Figs 17–18 View FIGURE 17 View FIGURE 18

Type material. Holotype. ♂ from Lago Janauari , 03°20'S, 60°17'W, Manaus, Amazonas, Brazil, 16.XI.1989, J. Adis et al. leg. ( INPA 5245 View Materials ). GoogleMaps  

Etymology. Noun in apposition taken from type locality.

Diagnosis. The male palp of A. janauari   sp. nov. is similar to that of A. bochica   , A. guatavita   , A. pae   , A. quimbaya   , A. zipa   and A. bifidus   sp. nov., with only two short dPED (no vPED; Fig, 18C). Among these, A. janauari   sp. nov. ( Fig. 18 View FIGURE 18 D) seems closer to A. guatavita   (see Galvis 2017: fig. 5C) and A. bifidus   sp. nov. ( Fig. 21 View FIGURE 21 D) by having similar RTA and RvTA (see note below). However, the projection on the basal portion of the embolus is absent in A. janauari   sp. nov. ( Fig. 18 View FIGURE 18 C), rounded in A. guatavita   (see Galvis 2017: fig. 5A) and bifid in A. bifidus   sp. nov. ( Fig. 21 View FIGURE 21 C).

Note. The structure in A. janauari   sp. nov. and A. bifidus   sp. nov. named herein as the RTA was referred in A. guatavita   by Galvis (2017) as DTS—dorsal tibial spur. On the other hand, Galvis’s RTA in A. guatavita   is possibly homologous to the structure referred herein as RvTA. Nonetheless, the homology among these structures is yet to be determined.

Description. Male holotype ( INPA 5245). Total length: 2.51. Carapace 1.20 long, 0.82 wide and 0.44 high. Ocular quadrangle 0.55 long. Anterior eye row 0.86 wide, posterior 0.65 wide. Legs: 3421; Length of leg I 1.51 (0.49 + 0.53 + 0.49); II 1.55 (0.49 + 0.57 + 0.49); III 1.79 (0.53 + 0.65 + 0.61); IV 1.75 (0.53 + 0.61 + 0.61). Palp ( Figs 18 View FIGURE 18 A–D): tibia with RvTA elongate and ventrally projected ( Figs 18 View FIGURE 18 C, 18D), RTA short and acute ( Figs 18 View FIGURE 18 B, 18D) and with small dorsal tubercle ( Fig. 18 View FIGURE 18 D); cymbium with large cymbial conductor ( Fig. 18 View FIGURE 18 C); embolic filament longer than straight, sclerotized portion ( Fig. 18 View FIGURE 18 C). Color in alcohol: thoracic area brown and cephalic area black; abdomen light brown; legs light brown ( Fig. 17 View FIGURE 17 A–B).

Female. Unknown.

Distribution. Known only from the type locality ( Brazil, Amazonas) ( Fig. 32 View FIGURE 32 ).
