2. Mottled cream and brown coloration, metafemora with dark blotches and transverse stripes, vittae on frons present but indistinct; proepisternum bilobed; pronotum with irregular, deep punctations ..................................................... 3

- Coloration variable but not mottled, metafemora with contrasting dark brown diagonal stripes, frons with strong dark vittae; proepisternum unilobed; pronotal punctures shallow and evenly spaced ................................................ 4

3. Costal margins of hemelytra with small brown spots; anterior lobe of proepisternum shorter than posterior lobe; right paramere without sharp triangular process .................................................................................... C. marmoreus

4. Body size ~ 1.9 – 2.1 mm (from clypeus to cuneus); orange-brown with brown and yellow markings; posterior margin of pygophore with minute tubercle to right of deep, folded groove ................................................... C. pilbarensis

- Body size less than 1.9 mm; coloration variable but not as above, pygophore without minute tubercle to right of folded groove ............................................................................................................................................................... 5

5. Body size ~ 1.5 – 1.7 mm (clypeus to cuneus); coloration highly variable, ranging from nearly all black to pale olive, usually with darker brown markings dorsally; folded groove on posterior margin of pygophore deep ........................ .............................................................................................................................................................
