Type material. Holotype ♀ ( USNM), ECUADOR: Orellana Province: Tiputini Biodiversity Station, nr Yasuní National Park , transect – T/1 Sta.1, 00°37'55"S 76°08'39"W, 05.II.1999, 220 – 250 m ( T. L. Erwin et al.).

Etymology. The specific epithet is an adjective, referring to the type locality of the new species.

Diagnosis. The new species differs from A. equatoriana Dupérré & Tapia, 2017 , the only other species of Anapistula known from Ecuador, in the shape of the epigyne: the lateral ducts (Ld) form an almost horizontal line (vs. V-shaped), the median duct (Md) is longer, and the receptacles are more widely spaced (cf. Fig. 5B–D and 5E). Additionally, the new species can be differentiated from other Neotropical congeners by the trajectory of lateral ducts, and the proportions of receptacles relative to the length of these ducts.

Description. Female. Habitus as in Fig. 5A. Total length 0.50. Carapace 0.24 long, 0.22 wide. Eyes: four in two diads. Body completely pale. Measurements of leg I: 0.67 (0.18, 0.09, 0.13, 0.11, 0.16). Additional information cannot be provided due to the damage inflicted on the specimen during the maceration of the epigyne.

Epigyne as in Fig. 5B–D; receptacles span ca. 1.57 times wider than length of epigynal plate; receptacles spaced by ca. 3 radii (1.5 diameters); lateral ducts (Ld) almost straight and forming horizontal line, forming a posterior bent close to receptacles.

Male. Unknown.

Distribution. Known only from the type locality in Orellana, eastern Ecuador.
