[Adapted from Brain (1920), De Lotto (1967), Gavrilov-Zimin & Chetverikov (2017), Granara de Willink (1999), Hodgson (1967, 1994) and Kondo & Gullan (2010)]

1. Legs rudimentary, with reduced number of segments......................................................... 2

- Legs normal, each with well-developed coxa, trochanter, femur, tibia and tarsus as typical for Coccidae ................ 3

2. Each stigmatic cleft containing 1 stigmatic seta; claw digitules similar in shape and size; rows of simple pores absent from body margin and along midline.......................................................... C. elytropappi (Brain)

- Each stigmatic cleft containing 3 stigmatic setae in addition to an uninterrupted row of marginal setae; claw digitules dissimilar in shape and size, with 1 conspicuously thicker than the other; row of simple pores present along body margin and along mid- line........................................................................... C. millari Gavrilov-Zimin 3. Stigmatic spines not differentiated from marginal setae. Posterior spiracular pore band incomplete, with only a few pores near area of posterior spiracle.................................................... C. patagonica Granara de Willink

- Stigmatic spines differentiated, totalling 1 (sometimes 2) per stigmatic cleft. Posterior spiracular pore band complete, extending from area around posterior spiracle to body margin....................................................... 4

4. Perivulvar pores present in small groups on either side of anal cleft only......................................... 5

- Perivulvar pores present along either side of anal cleft, with some pores extending anterolaterally on posterior abdominal segments............................................................................................... 6

5. Marginal setae all of 1 length. Dorsal derm without areolations. Antennae 7 or 8 segmented....... C. lounsburyi Cockerell

- Marginal setae of 2 lengths, 1 type conspicuously shorter than the other. Dorsal derm with areolations. Antennae 6 or 7 segmented............................................... C. corpoica Kondo & Montes sp. nov. (Figs 1A, B & C; 2)

6. Preopercular pores present along midline from just anterior to anal plates to about mesothorax. Dorsal microducts each without a septum, appearing unilocular; sparsely scattered throughout dorsum, not intermixed with preopercular pores, nor present alongside marginal setae. Antennae 7 segmented...................................... C. chilensis Kondo & Gullan

- Preopercular pores present along midline from just anterior to anal plates to head margin. Dorsal microducts each with a septum, appearing bilocular; intermixed with preopercular pores, also present alongside marginal setae. Antennae 5 to 8 segmented............................................................................................. 7

7. Test of live insect highly convex, like a small bivalve shell. Stigmatic spines bluntly spinose, each as long as a marginal seta. Thick and large ventral submarginal setae absent from anteriorly on head and from anal lobes. Antennae 5 or 6 segmented.......................................................................................... C. zizyphi (Brain)

- Test of live insect only slightly convex, not shaped like a small bivalve shell. Stigmatic spines sharply spinose, each about twice as long as, or longer than a marginal seta. A pair of thick and large ventral submarginal setae present anteriorly near head (ventral cephalic setae); each anal lobe also with a thick and large seta (large anal lobe seta). Antennae 7 or 8 segmented..................................................................... C. ica Montes & Kondo sp. nov. (Figs 1F, 3)
