Etymology. The species is dedicated to Joachim Adis (1950-2007) for his important contributions about the Amazonian forest and its ecology and for his longstanding contribution to the study of arachnids in South America; name in genitive case.

Diagnosis. The males of Sparianthina adisi  sp. n. are distinguished from those of the remaining species of the genus by the bifid RTA with similar sized branches ( Figs 66-67View Figures 65-67). It resembles Sparianthina deltshevi  sp. n. by the long and slender projection at the retrolateral base of the embolus ( Figs 66View Figures 65-67, 69View Figures 68-70), but is distinguished from this species by exhibiting a much narrower projection.

Description. Male (AMNH, holotype). Total length 6.6. Prosoma: 3.0 long, 3.0 wide. Opisthosoma: 3.5 long, 2.3 wide. Eye diameters and interdistances: AME 0.16, ALE 0.22, PME 0.20, PLE 0.26, AME–AME 0.08, AME–ALE 0.04, PME–PME 0.22, PME–PLE 0.22, AME–PME 0.16, ALE–PLE 0.18. Legs: I: femur 4.3, patella 1.5, tibia 4.5, metatarsus 3.9, tarsus 1.4, total 15.6; II: 4.9, 1.6, 4.9, 4.2, 1.6, 17.2; III: 3.9, 1.3, 3.4, 3.3, 1.2, 13.1; IV: 4.5, 1.2, 4.1, 4.2, 1.5, 15.5. Spination: femur I–III: p1-1-1; d0-1-1; r1-1-1; femur IV: p1-1-1; d0-1-1; r0-0-1; tibia I–II: v2-2-2-2-0; tibia III–IV: p1-0-1; d0-0-1; r1-0-1; v2-2-0; metatarsus I–II: v2-2-0; metatarsus III: p1-1- 0; r1-1-0; v2-2-0; metatarsus IV: p1-1-2; r1-1-2; v2-2-0.

Palp as in diagnosis. Embolus and conductor arising from tegulum at a 9-o’clockposition ( Fig. 66View Figures 65-67). Ventral tibial lobe small and slightly shifted retrolateral. Tegular subembolic projection notched prolaterally to the subtegulum. Conductor hyaline and laminar. Sperm duct running submarginally ( Figs 65-67View Figures 65-67).

Colouration. Prosoma orange-brown, slightly darker at eye area and brown along fovea and thoracic striae. Chelicerae orange. Pedipalps dark orange. Legs orange with light brown markings at spine bases. Sternum yellow with orange margins. Gnathocoxae pale yellow. Labium pale yellow, light brown at base. Opisthosoma pale yellow ( Fig. 77View Figures 74-79).

Female unknown.

Variation. Males (n=8): total length 6.2-7.4; prosoma 3.0-3.6; femur I 3.6-4.5.
