Description
COLOUR PATTERN. Body length up to 1.9 mm. Ground color pale yellow. Eyepatch dark blue. Ant. IV and tibiotarsus with blue pigment. Lateral margin of Th. II and III also with a little blue pigment ( Fig. 1 View Fig A−C).
HEAD. Antenna 0.43−0.57 times as long as body. Ratios of length of antennal segments I:II:III:IV = 1:1.6−2.0:1.6−2.4:2.5−4.1. Distal part of Ant. IV with many sensory setae, normal ciliate setae and apical bulb bilobed ( Fig. 2A View Fig ). Dorsal cephalic chaetotaxy with 6−7 antennal (An), 5 (4) median (M 1 −M 4, an additional seta between M 2 and M 3 rarely absent) and 8 sutural (S 0 −S 5, S 4i, S 5i) mac. Interocular area with p, s, t setae. Eyes 8+8, G and H smaller ( Fig. 2B View Fig ). Labral setae as 4/5, 5, 4, all slender; prelabral setae ciliate, other smooth; distal margin of labrum with 4 papillae, each with 1 denticle ( Fig. 2C View Fig ). Lateral process of labial palp straight, as thick as normal setae, with tip not reaching apex of labial papilla ( Fig. 2D View Fig ). Labial triangle setae as in Fig. 2E View Fig , all finely ciliate.
THORAX. Dorsal macrochaetae shown as in Fig. 2F View Fig . Th. II with 2 (m1, m2) medio-median, 2 (m4, m4i) medio-lateral and 14−18 posterior mac on each side, 2 specialized setae (S-setae) on antero-lateral margin not clearly seen. Th. III with 13−15 median and 7 (m5, a6, a6i, p5, p6, m6, m6e) lateral mac on each side. Trochanteral organ with 26−30 smooth spiny setae ( Fig. 2G View Fig ). Unguis with 4 inner teeth, one pair located 0.38−0.39 from base of inner edge of unguis, distal unpaired two respectively at 0.68−0.71 and 0.84−0.89 distance from base. Unguiculus acuminate and outer edge serrate. Tenent hair thick with clavate tip, almost equal length to inner side of unguis ( Fig. 2H View Fig ).
ABDOMEN. Abd. IV 4.2−8.0 times as long as Abd. III along dorsal midline. Dorsal mac shown in Figs 2I View Fig and 3A View Fig . Abd. I with 4 (m2, m3, m4, m4p) mac. Abd. II with 4 (a2, m3, m3e, m3ep) (rarely 5, a3 present), 1 (m5) lateral mac and 2 S-setae. Abd. III with 2 (a2, m3) dorso-central, 3 (am6, pm6, p6) lateral mac and 3 S-setae ( Fig. 2I View Fig ). Abd. IV with 11−18 central (rarely 7, A3, A4, A6, B3, B4, B5, B6 always present) and 15−17 lateral mac as in Fig. 3A View Fig . Ventral tube anteriorly with 3 large and about 9 small ciliate setae ( Fig. 3B View Fig ), posteriorly with 2 apical smooth setae and about 36 ciliate setae of different sizes ( Fig. 3C View Fig ), laterally with 6 smooth and 8 ciliate setae of different sizes ( Fig. 3D View Fig ). Manubrial plaque with 8−9 ciliate setae and 3 pseudopores on each side ( Fig. 3E View Fig ). Dens without spines, uncrenulated dens 1.5−1.7 times as long as mucro. Mucro bidentate, two teeth subequal and tip of basal spine reaching subapical tooth ( Fig. 3F View Fig ).
SCALES. All scales spinulate type and present on Ant. I, head, body, legs and ventral tube, ventral side of manubrium ( Fig. 3G View Fig ).
Remarks
The new species can be distinguished from other species of the genus in its color pattern. It is very similar to Chinese species W. guangxiensis Shi & Chen, 2004 and W. shi Pan, Zhang & Chen, 2006 in scales and chaetotaxy on Abd. I, but their color pattern, labial triangle setae, chaetotaxy on Abd. II and III and ungual inner teeth are different as shown in Table 1 View Table 1 .
