Head. Ant I dorsally with 5 mac and 5 basal spiny smooth mic (Figure 10E). Posterior labial chaetotaxy series ‘CG’ with 6 ciliate chaetae (<b>CG 1–3</b>, <b>CG 5</b>, <b>CG 6p–7</b>) and 2 serrated mic (<b>CG 4</b>, <b>CG 6</b>); series ‘PLM’ with 2 ciliate chaetae (<b>PLM 1–2</b>); series ‘PLE’ with 2 ciliate chaetae (<b>PLE 1–2</b>); lateral side with about 17 ciliate chaetae (Figure 11E). Dorsal chaetotaxy. Th II with 1 ‘m’ mac present or absent (<b>m1</b>), 3–5 ‘p’ mac (<b>p1i</b>, <b>p1–4</b>), <b>p1i</b> and <b>p2</b> present or absent. Th III with 4–5 ‘p’ mac (<b>p1i</b>, <b>p1–3</b>, <b>p5</b>), <b>p1</b> present or absent (Figure 12E). Abd I with 1–2 ‘m’ mac (<b>m3</b>, <b>m4</b>), <b>m4</b> present or absent (Figure 13E). Abd III with 2 ‘m’ mac (<b>am6</b>, <b>pm6</b>); 1 ‘p’ mac (<b>p6</b>) and 1 ‘p’ mes (p7i) (Figure 14B). Abd IV with 2 ‘A’ mac (<b>A1</b>, <b>A6</b>); 1 ‘Ae’ mac (<b>Ae1</b>); 3 ‘B’ mac (<b>B3–5</b>); 1 ‘Be’ mac (<b>Be1</b>); 1 ‘C’ mac (<b>C1)</b>; 4 ‘E’ mac (<b>E1-4</b>); 4 ‘F’ mac (<b>F1–F3p</b>); 4 ‘Fe’ mac (<b>Fe1–3</b>, <b>Fe6</b>); posterior side with 3 sens type IV (<b>ps</b> and two unnamed) (Figure 14H).

Trochanteral organ with 14 smooth spine-like chaetae (Figure 16E). 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 18 A-B). Manubrial plate with 2 chaetae (Figure 19C). Mucro with 4 teeth (<b>d1</b>, <b>ap</b>, <b>v1-2</b>) (Figure 19G). <i>Etymology</i> The name “maculipenis”, from Latin, refers to the human peniform dorsal spot on abdomen IV of this new species. <i>Remarks</i> <i>Salina maculipenis</i> <b>sp.n.</b> resembles <i>S. tocantinensis</i> <b>sp.n.</b> 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, <i>S. maculipenis</i> <b>sp.n.</b> differs from <i>S. tocantinensis</i> <b>sp.n.</b> by dorsal chaetotaxy of Abd III with 3 lateral mac (6 in <i>S. tocantinensis</i> <b>sp.n.</b>) and Abd IV with 4 mac in ‘Fe’ series (2 in <i>S. tocantinensis</i> <b>sp.n.</b>). Others characteristics that differs <i>S. maculipenis</i> <b>sp.n.</b> from <i>S. tocantinensis</i> <b>sp.n.</b> are Ant I with 5 mac (4 in <i>S. tocantinensis</i> <b>sp.n.</b>), cephalic groove with 2 serrated mic (1 in <i>S. tocantinensis</i> <b>sp.n.</b>), manubrial plate with 3 chaetae (2 in <i>S. tocantinensis</i> <b>sp.n.</b>), and collophore with 11 anterior chaetae (3 mac subequal), while in <i>S. tocantinensis</i> <b>sp.n.</b> has 7 anterior chaetae (1 mac smaller). The color pattern of <i>S. maculipenis</i> <b>sp.n.</b> also differs by Th II–Abd III posteriorly with one transverse band and Abd IV with a penis-shaped spot, while in <i>S. tocantinensis</i> <b>sp.n.</b> has blue spots on body and legs.
