Diagnosis: 3.20–3.40 mm long (mean = 3.32 mm; n = 5); 2.83–2.91 times as long as wide. This species is distinguished by the discal interstrial punctures confused, protibia distinctly triangular, anterior margin of the pronotum with a clear row of eight moderate serrations. This species is very similar to C. cattienensis and can be distinguished by the larger size and narrower form.
