Description.

Size. Body length up to 2.23 mm.

Coloration. Ground colour pale yellow; antennae with scattered brown pigment; eye patches dark blue; brown stripe present from head to Abd. III laterally; middle part of Abd. II-III with brown pigment; medial and posterior margin of Abd. IV with pair of irregular brown patches, respectively; brown pigment scattered on antennae and legs (Figs 49 View Figures 49, 50 , 50 View Figures 49, 50 ).

Head. Antenna not annulated and 1.45-1.49 times length of body. Ratio of Ant. I-IV as 1.00/0.90-0.98/0.58-0.63/1.50-1.54. Distal part of Ant. IV with many sensory chaetae and normal ciliate chaetae, without apical bulb (Fig. 51 View Figures 51–56 ). Ant. III organ not clearly seen. Dorsal chaetotaxy of head as in Fig. 52 View Figures 51–56 , An series with six mac, A with four mac or mes, S with eight mac, P with two mac. Eyes 8+8, G & H smaller than others; interocular chaetae as p, r, t; frontal spines 4+4, all serrate. Prelabral chaetae four, ciliate; labral chaetae 5, 5, 4, smooth and pointed, a0, a1 longer than a2; labral papillae absent (Fig. 53 View Figures 51–56 ). Basal chaeta on maxillary outer lobe thick and blunt; sublobal plate with three smooth chaetae-like processes (Fig. 54 View Figures 51–56 ). Lateral process (l. p.) of labial palp E differentiated, as thick as normal chaeta, with tip not reaching apex of papilla E (Fig. 55 View Figures 51–56 ). Labial base with MREL1L2, all ciliate and R 0.53-0.68 length of M (Fig. 56 View Figures 51–56 ).

Thorax. Tergal ms formula on Th. II-Abd. V as 1, 0/1, 0, 1, 0, 0, sens as 1, 1/0, 2, 2, 37-41, 3 (Figs 57 View Figures 57–59 , 60 View Figure 60 - 62 View Figures 61, 62 ). Th. II with medial five (m1, m4, m4p, a5, m5) mac, posterior ten (p1i, p1, p2, p2a, p2a2, p2p, p2e, p2ep, p3, p4) mac, one ms and one sens. Th. III with anterior-lateral five (a4, a5, m5, a6i, a6), usually posterior 15 (p1i2a rarely absent) mac, one sens (Fig. 57 View Figures 57–59 ). Trochanteral organ with 63-81 chaetae (Fig. 58 View Figures 57–59 ). Tenent hair clavate, 1.10-1.15 as long as inner edge of unguis; unguis with four inner teeth, most distal tooth very faint, basal pair located at 0.37-0.41 distance from base of inner edge of unguis, unpaired teeth at 0.58-0.61 and 0.70-0.78 distance from base, respectively; unguiculus lanceolate, with one inner tooth and outer edge slightly serrate (Fig. 59 View Figures 57–59 ).

Abdomen. Range of Abd. IV length as 10.00-12.00 times as dorsal axial length of Abd. III. Abd. I usually with 11 (a1-3, a5i, a5, a5p, m2-4, m4i, p5 rarely absent) mac and one ms. Abd. II with central six (a2, a3, m3, m3e, m3ei, m3ep), lateral three (m5, a6, p6) mac. Abd. III with central two (a2, m3), lateral three (am6, pm6, p6) mac and 10-14 mes (Fig. 60 View Figure 60 ). Abd. IV with 35-39 elongate and two (as, ps) normal sens, medial 15-18 and posterior 18-23 mac or mes, lateral 8-9 mac (Fig. 61 View Figures 61, 62 ). Abd. V with three sens (Fig. 62 View Figures 61, 62 ). Ventral tube with 25-29 ciliate chaetae on each side anteriorly (Fig. 63 View Figures 63–70 ); numerous ciliate chaetae and 2-3 apical smooth chaetae posteriorly (Fig. 64 View Figures 63–70 ); 17-24 smooth and 10-17 ciliate chaetae on each lateral flap (Fig. 65 View Figures 63–70 ). Manubrial plaque with four ciliate mac and one pseudopore (Fig. 66 View Figures 63–70 ). Dens without spines. Mucro with six (v1, v2, v3, d1, d2, i.l.) teeth (Fig. 67 View Figures 63–70 ).

Scales. Scales present on head, body, legs (Figs 68 View Figures 63–70 , 69 View Figures 63–70 ); Ant. I-III and ventral side of manubrium and dens with narrower scales (Fig. 70 View Figures 63–70 ). Ant. IV, ventral tube and tenaculum without scales.
