Total length (head + trunk) of holotype 1.88 mm. Specimens pale white with light yellow pigment on Ant I–IV and distal half of femora to distal tibiotarsi. Eye patches black ( Figure 9IView Fig).

Head. Ant I dorsally with 3 mac and 6 basal spiny smooth mic ( Figure 10IView Fig). Posterior labial chaetotaxy; series ‘CG’ with 6 ciliate chaetae ( CG 1-3, CG 5, CG 7–7e) and 2 serrated mic ( CG 4, CG 6); series ‘PLM’ with 3 ciliate chaetae ( PLM 1–3); series ‘PLE’ with 2 ciliate chaetae ( PLE 1–2); lateral side with about 15 ciliate chaetae ( Figure 11IView Fig).

Dorsal chaetotaxy. Th II with 1 ‘m’ mac (m7), and 1 ‘p’ mac (p3). Th III with 1 ‘p’ mac (p3) ( Figure 12IView Fig). Abd I with 1 ‘m’ mac (m4) ( Figure 13IView Fig). Abd III with 1 ‘a’ mac (a7), 2 ‘m’ mac (am6, pm6), and 3 ‘p’ mac (p6, p 7i and one unnamed) (similar to S. brasiliana  sp.n., Figure 14AView Fig). Abd IV with 2 ‘A’ mac ( A 1, A 6); 1 ‘Ae’ mac (Ae1); 3 ‘B’ mac ( B 3–5); 1 ‘Be’ mac (Be1); 1 ‘C’ mac ( C 1); 4 ‘E’ mac (E1-4); 4 ‘F’ mac ( F 1– F 3p); 2 ‘Fe’ mac (Fe1–3); posterior side with 3 sens type IV (ps and two unnamed) (similar to S. brasiliana  sp.n., Figure 14DView Fig). Abd V with 2 ‘a’ mac (a3, a5); 3 ‘m’ mac (m2–3, m5); and 5 ‘p’ mac (p0-4) (similar to S. brasiliana  sp.n., Figure 15AView Fig).

Appendages. Trochanteral organ with 15 smooth spine-like chaetae ( Figure 16IView Fig). Collophore anterior side with 1 mac, 2 smaller mes of equal length, and 5 proximal smooth mic; posterior side with 1 apical and 1 subapical smooth chaetae; lateral flap formula 5(s), 5(m), 5(i) smooth chaetae, 2 inferior larger ( Figure 18EView Fig). Manubrial plate with 3 chaetae ( Figure 19CView Fig). Mucro with 3 teeth (d1, ap, v1) (as S. peruana  sp.n., Figure 19HView Fig).


The name “ unisetosa  ” refers to dorsal chaetotaxy of the Th II to Abd I, each with one chaeta (from Latin: uni = one and setosa = seta or chaeta).
