Differential diagnosis. The new species is very similar to C. pitangus  in having the prodorsal shield with lateral incisions at the level of the scapular setae, but can be distinguished from that species mostly by characters observed in females. In females of C. campoflicker  sp. nov., setae h1 are short and spiculiform, setae d1 and d2 are arranged in a trapezoid, setae e2 are about as twice as robust as f2, and the lateral margins of hysteronotal shield are sinuous, with noticeable irregular projections at level of setae d2; in males, setae 1a are close to tips of epimerites I and clearly distant from the apical level of epimerites II. In females of C. pitangus  , setae h1 are thin, setiform, setae d1 and d2 are arranged in an almost transverse line, setae e2 are nearly as robust as f2, and the lateral margins of the hysteronotal shield are straight; in males of that species, setae 1a are situated at level of tips of epimerites II and noticeably distant from tips of epimerites I.

Etymology. The specific epithet is taken from the English common name of the host, the Campo Flicker.
