Total length (head + trunk) of holotype 1.9 mm. Specimens pale white with dark blue pigments on anterior head, Ant I–II distally and Ant IV; orange pigments on basal Ant IV, Ant I–II medially, lateral head, Th II anteriorly, Th II–Abd III posteriorly with one transverse band, Abd III and IV posteriorly with one lateral spot, Abd IV with one central strong spot resembling a human penis; Abd V posteriorly, and distal half of the femur to tibiotarsus; eyepatches yellow and black ( Figure 9EView Fig).

Head. Ant I dorsally with 5 mac and 5 basal spiny smooth mic ( Figure 10EView Fig). Posterior labial chaetotaxy series ‘CG’ with 6 ciliate chaetae ( CG 1–3, CG 5, CG 6p–7) and 2 serrated mic ( CG 4, CG 6); series ‘PLM’ with 2 ciliate chaetae ( PLM 1–2); series ‘PLE’ with 2 ciliate chaetae ( PLE 1–2); lateral side with about 17 ciliate chaetae ( Figure 11EView Fig).

Dorsal chaetotaxy. Th II with 1 ‘m’ mac present or absent (m1), 3–5 ‘p’ mac (p1i, p1–4), p1i and p2 present or absent. Th III with 4–5 ‘p’ mac (p1i, p1–3, p5), p1 present or absent ( Figure 12EView Fig). Abd I with 1–2 ‘m’ mac (m3, m4), m4 present or absent ( Figure 13EView Fig). Abd III with 2 ‘m’ mac (am6, pm6); 1 ‘p’ mac (p6) and 1 ‘p’ mes (p7i) ( Figure 14BView Fig).

Appendages. Trochanteral organ with 14 smooth spine-like chaetae ( Figure 16EView Fig). Collophore anterior side with 3 subapical mac of equal length, and 8 proximal smooth mic; posterior side with 1 apical and 1 subapical smooth chaetae; lateral flap formula 4(s), 6(m), 5(i) smooth chaetae, 2 inferior larger ( Figures 18View Fig A-B). Manubrial plate with 2 chaetae ( Figure 19CView Fig). Mucro with 4 teeth (d1, ap, v1-2) ( Figure 19GView Fig).


The name “maculipenis”, from Latin, refers to the human peniform dorsal spot on abdomen IV of this new species.


Salina maculipenis  sp.n. resembles S. tocantinensis  sp.n. in general morphology, and dorsal chaetotaxy of Th II–III with at least 3 central mac, Abd I with 1 or more central mac, and Abd IV with 8 central mac. However, S. maculipenis  sp.n. differs from S. tocantinensis  sp.n. by dorsal chaetotaxy of Abd III with 3 lateral mac (6 in S. tocantinensis  sp.n.) and Abd IV with 4 mac in ‘Fe’ series (2 in S. tocantinensis  sp.n.). Others characteristics that differs S. maculipenis  sp.n. from S. tocantinensis  sp.n. are Ant I with 5 mac (4 in S. tocantinensis  sp.n.), cephalic groove with 2 serrated mic (1 in S. tocantinensis  sp.n.), manubrial plate with 3 chaetae (2 in S. tocantinensis  sp.n.), and collophore with 11 anterior chaetae (3 mac subequal), while in S. tocantinensis  sp.n. has 7 anterior chaetae (1 mac smaller). The color pattern of S. maculipenis  sp.n. also differs by Th II–Abd III posteriorly with one transverse band and Abd IV with a penis-shaped spot, while in S. tocantinensis  sp.n. has blue spots on body and legs.
