Remarks

• Systematics: The adult females of Waxiella vuilleti are extremely similar to those of W. egbara and W. mimosae but differ mainly in the much larger number of tubular ducts in the cephalic region (about 200 as compared with less than 100 on the other 2 species) and the very large size of each group of stigmatic setae (as large as or even larger than the sclerotised area of the caudal process - smaller on the other 2 species). On W. vuilleti, each group of conical stigmatic setae is roundly oval to egg-shaped (widest towards base of each group) with a very broad base; each group with about 12-15 conical setae across the basal width, about 60-70 conical setae around dorsal margin and some 30+ conical setae across the greatest width. In addition, the sharply-spinose stigmatic setae form a fairly narrow group across each stigmatic cleft, with 40+ setae in each group. All of these parameters are significantly greater than on most W. egbara. Hodgson & Peronti, 2012
• Structure: Unmounted material. "The waxy test of this magnificent species averages 22 mm long by 17 mm wide; height 8-9 mm, but 15-17 mm when the depth of the wax extending down on each side of the branch is included. The wax test is extremely thick (6-7 mm), soft and easily depressed; colour white washed with rusty shades. When damaged, a colorless liquid is released with a characteristic odour. The wax test showed no indications of the structure of the underlying insect, which was quite small compared with the thickness of the test, averaging 6 mm long, 4-5 mm wide and 2 mm high. The insect was basically brown and hexagonally shaped. On either side, there are 2 lateral angles corresponding to the ends of spiracular furrows. From each of these angles emerges a straight line of clear white waxy filaments, quite different from the greyish-white wax of the test. Mid-dorsally, there is a longitudinal peak, ending abruptly anteriorly and slanting down posteriorly. Posteriorly is the anal process, truncated apically and strongly protruding, slightly tilted forward". (Much shortened, rather free translation of Marchal, 1909b in Hodgson & Peronti, 2012).
• General Remarks: Detailed description and illustration in Hodgson & Peronti, 2012. Based on the information in Hodgson & Peronti,2012, the record by Newstead (1917) in Nigeria has been removed from ScaleNet.
