Labial chaetae Mmrel 1 l 2 and M ciliate, other smooth; M 0.45–0.70 times as long as m, chaeta r reduced ( Fig. 11 View Fig G–H). Labral chaetae 4/5, 5, 4, all smooth; labral papillae 4, inner papillae apically rounded, outer papillae truncate ( Fig. 12A View Fig ). Head dorsal chaetotaxy with 6 median (M), 6 sutural (S), 6 interocular and 3 postsutural (Ps) chaetae, posterior part not clearly seen ( Fig. 12B View Fig ).

THORAX. Th. II protruded over head and thorax, without mac. Th. II with 13 (a5, m1−2, m 1i, m2p, m4−5, p1−6) mic. Th. III with 16 (a1−4, a6−7, m2, m4−6, p1−6) mic ( Fig. 12C View Fig ). Coxa I with 7 ciliate mac and 2 pseudopores ( Fig. 13A View Fig ). Coxa II with 8 ciliate mac in anterior row, 7 ciliate mac in posterior row and 3 pseudopores ( Fig. 13B View Fig ). Coxa III with 9 ciliate mac and 2 pseudopores ( Fig. 13C View Fig ). Trochanteral organ with 27−38 smooth, spiny chaetae ( Fig. 13D View Fig ). Tenent hair weakly ciliate, slightly shorter than inner side of unguis, with tip strongly clavate. Unguis with 4 inner teeth, basal pair larger, located at a distance of 0.33−0.43 from base of inner edge of unguis, unpaired two subequal, at a distance of 0.65−0.69 and 0.87−0.88 from base, respectively. Unguiculus acuminate with outer edge serrate ( Fig. 13E View Fig ).

III with 1 central S-chaeta (as) and 1 lateral ms, 7 (a3, a7, m3−4, m7, p3, p5) mic, 9 (mi, m1, a2, li, lm, ll, a6, im, em) ciliate, accessory fan-shaped chaetae, 1 (am6) ciliate mic and 3 (pm6, p6, p7) ciliate mac ( Fig. 14A View Fig ). Abd. IV with 1 anterior (as) and 1 posterior (ps) short S-chaetae, 6−13 median elongate S-chaetae, all black as short S-chaetae, 21 (A2−6, B2−3, C2−4, C1p, D1p, D3, T1, T3, T5−7, E1, F1−2) mic, 6 (m, a, s, D1, pi, pe) ciliate, accessory fanshaped chaetae, 4 (B4−6, C1) median ciliate mac and usually 7 (E2−4, E4p, F3, F3p, Te3) lateral ciliate mac ( Fig. 15A View Fig ).

Mucro bidentate and subequal, basal spine reaching apex of basal tooth with an accessory spinelet ( Fig. 16H View Fig ).

Remarks

The new species is most similar to the species Lepidocyrtus (Setogaster) merapicus Yoshii & Suhardjono, 1989 and L. (S.) sotoi Bellini & Godeiro, 2015 in colour pattern since no blue pigment is present on their body tergites, but the colour pattern on the antennae, scales on Ant. I, femora and tibiotarsi, as well as the shapes of the prelabral and labial chaetae and the inner teeth on the unguis are different ( Table 3 View Table 3 ).
