Diagnosis.
As in
Ale-Rocha (2006)
, plus frons narrow (at mid-length narrower than width of anterior ocellus) (
Fig. 14
). Veins M
1
and M
4
reaching the wing margin (
Fig. 50
). Hind femur slightly clavate. Fore and mid tarsomeres 3– 4 and hind tarsomeres 3–5 ventrally with short, blunt, black spine-like setae.
Type material examined.

, INPA).
Remarks.
In the original description, a photo of the wing of
C. masneri
was presented (
Ale-Rocha 2006, fig. 40
), which highlighted the sinuosity near the apex of vein R
1
as diagnostic of the species. After re-examining the
paratypes
and a photo of the
holotype
, we noted that vein R
1
is not so sinuous near the apex and does not run closely to R
2+3
(
Fig. 50
) as previously described, indicating that the wing in
Ale-Rocha (2006)
does not belong to this species. Therefore, we provide here a new wing photograph of a male
paratype
.
