All deposited in SAM . Description. Body length up to 1.7mm . Ground colour yellow; eyes patches and Ant. II −IV dark blue ( Fig. 6 ); some specimens with blue pigment on dorsal side of abdomen, especially lateral margin ( Fig. 7 ). Antenna 0.54−0.67 times length of body. Ratio of Ant. I −IV as 1.0/2.0 − 2.1/1.7 − 2.0/2.2−2.3. Distal part of Ant. IV with many sensory chaetae and normal ciliate chaetae and an apical bulb ( Fig. 67 ). Eyes 8+8, G and H smaller. Interocular chaetae as p, q, r, s, t, p chaeta larger than others. Dorsal cephalic chaetotaxy with 4 antennal (An1, An2, An3a1, An3), 2 median (M2, M4) and 7 sutural (S0, S2, S3, S4, S 4i , S5, S 5i ) macrochaetae ( Fig. 68 ). Basal chaetae of labium as M, R, E, L1, L2, all ciliate ( Fig. 69 ). Dorsal macrochaetae shown as in Fig. 70 . Th. II with 3 (m1, m 2i , m2) macrochaetae in Mm area and 4 (m 4i , m4, m4p, a5) macrochaetae in Ms area. Th. III with 3 (a1, a2, a3) macrochaetae in Am area and 6 (a 4i 2, a 4i , a4, a5, m 5i , m5) macrochaetae in As area. FIGURES 52−66. Drepanura cinquilineata Womersley, 1934: 52 , apex of Ant.

Drepanura citricola Womersley, 1934: 67 , apex of Ant. IV; 68, dorsal chaetotaxy of head; 69, labium; 70, chaetotaxy of Th. II −III; 71, trochanteral organ; 72, foot complex; 73, chaetotaxy of Abd. I −III; 74, chaetotaxy of Abd. IV; 75, anterior face of ventral tube; 76, lateral flap of ventral tube; 77, plaque of manubrium; 78, mucro. Trochanteral organ with 9−10 chaetae ( Fig. 71 ). Inner differentiated tibiotarsal chaetae ciliate, the most distal one smooth. Tenent hair clavate, 1.3−1.4 × length of inner side of unguis; unguis with 4 inner teeth, paired teeth located at about 0.4 distance from base to claw, and 2 unpaired teeth, first one at 0.7 and distal one at 0.8 distance from base respectively, dorsal tooth present; unguiculus acuminate and outer edge serrate ( Fig. 72 ). Abd. IV 3.6−4.3 times as long as Abd. III along dorsal midline. Abd. I with 4(5) (m 2i , m2, m3, m4, rarely a1) macrochaetae. Abd. II with 4 central (a2, a3, m3, m3e) and 1 lateral (m5) macrochaeta, Abd. III with 1 central (m3) and 3 lateral (am6, pm6, p6) macrochaetae ( Fig. 73 ). Macrochaetae and bothriotricha of Abd. IV as shown in Fig. 74 , lateral side with 13−14 macrochaetae on each side, central part with 18 macrochaetae. Ventral tube anteriorly with 10−11 ciliate chaetae on each side ( Fig. 75 ); posteriorly not clearly seen; each lateral flap with 3 smooth chaetae and 6 ciliate chaetae ( Fig. 76 ). Tenaculum with 1 large striate chaeta. Manubrial plaque with 3 ciliate chaetae and 2 pseudopores ( Fig. 77 ). Distal smooth part of dens 2.6−3.6 times as long as mucro in length. Mucro falcate and tip of basal spine not reaching apex of apical tooth ( Fig. 78 ). Remarks. The species can be easily distinguished from the other Australian species in the colour pattern, as nearly the whole body is a uniform yellow. Type locality. Australia : Perth. Distribution.
