Key to adult females in the Waxiella africana- group (excluding W. erithraeus (Leonardi) and W. mimosae neghellii (Bellio)) .

1. Ventral tubular ducts present in a large group in cephalic region................................................. 2

- Ventral tubular ducts absent from cephalic region............................................ W.gwaai (Hodgson)

2. Each stigmatic cleft with an almost round group of conical setae, each group about as wide as long; each group with a broad base and with no clear indication of a deep cleft; each group surrounded by a fairly narrow area of sclerotisation on mature individuals, with greatest width of sclerotised area not much greater than that covered by the stigmatic setae............. 3

- Each stigmatic cleft with an oval group of conical setae, each group clearly narrower than long and each group with a narrow base within a distinct, deep cleft; each group with a broad border of sclerotisation on mature individuals, with greatest width of sclerotised area generally more than twice width of stigmatic setae.............................................. 5

3. Pregenital disc-pores restricted to abdominal segments, never present on thorax; spiracular disc-pore band without multilocular disc-pores along anterior border and disc-pores generally absent mesad to each spiracle; tubular ducts generally absent submarginally on head and thorax posterior to each scape...................................................... 4

- Pregenital disc-pores present on thorax associated with hind coxae and on all abdominal segments; multilocular disc-pores also present along anterior border of each spiracular disc-pore band and also mesad to each spiracle; tubular ducts often present submarginally on head and/or thorax posterior to each scape.................................. W. mimosae (Signoret) .

4. With a group of 100 or fewer ventral tubular ducts in cephalic region; group of conical stigmatic setae not huge, not as big as area of sclerotisation of caudal process, generally with fewer than 50 conical setae around the outer circumference of each group, generally with 25 or fewer setae across widest part of each group and generally with fewer than 35 sharply-spinose stigmatic setae in each cleft............................................................. W. egbara (Cockerell)

- With a group of about 200 ventral tubular ducts in cephalic region; group of conical stigmatic setae huge, subequal in size to area of sclerotisation of caudal process, with more than 60 conical setae around the outer circumference of each group, 30+ setae across widest part of each group and with more than 40 sharply-spinose stigmatic setae in each cleft W. vuilleti (Marchal)

5. Present in countries surrounding the Sahara; each stigmatic cleft with 6–10 conical stigmatic setae across base of group, generally more than 40 conical setae around the circumference of each group and 18–40 sharply-spinose stigmatic setae in each cleft........................................................................ W. senegalensis (Marchal)

- Present in southern Africa; each stigmatic cleft with 2–7 conical stigmatic setae across base of group, generally less than 35 conical setae around the circumference of each group and 9–23 sharply-spinose stigmatic setae in each cleft................................................................................................... W. africana (Green)
