Etymology. The species is dedicated to Michael Saaristo (1938-2008) for his many contributions to the taxonomy of spiders; name in genitive case.

Diagnosis. The males of Sparianthina saaristoi  sp. n. are distinguished from those of the remaining species of the genus by the slender embolus without projections and by the RTA having only one dorsal branch ( Figs 71-73View Figures 71-73).

0.24, PME–PLE 0.26, AME–PME 0.20, ALE–PLE 0.18. Legs: I: femur 4.3, patella 1.5, tibia 4.3, metatarsus 3.9, tarsus 1.5, total 15.5; II: 4.8, 1.5, 5.0, 4.4, 1.7, 17.4; III: 3.9, 1.3, 3.5, 3.4, 1.3, 13.4; IV: 4.6, 1.3, 4.1, 4.6, 1.6, 16.2. 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: d1-0-1; v2-2-2- 2-0; tibia III–IV: p1-0-1; d1-0-1; 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. Sperm duct running marginally at the distal and proximal tegulum and submarginally at the retrolateral tegulum ( Fig. 72View Figures 71-73).

Colouration. Prosoma brownish orange, brown along fovea and thoracic striae. Eye borders black. Chelicerae orange-brown. Legs and pedipalps orange with brown markings at spine bases. Labium and gnathocoxae brownish-orange, distally lighter. Sternum pale orange with slightly darker margins. Opisthosoma yellowish-grey ( Fig. 79View Figures 74-79).

Female unknown.
