Araripus Carmo and Sampronha gen. nov.

Type species.

Araripus crassitibialis sp.nov.

Diagnosis.

Large insects (length = 23.5 mm); head narrower than thorax; fore tibia swelled; frons slightly divergent at vertex and apparently not very broad; basal callus absent, but callosity visible at the dorsal half of frons; R4 strongly sinuous at apex, parallel to R2+3 extremity; angle between R4 and R5 less than 90°; vein r-m inclined anteriorly; abdomen very long, nearly twice the thorax length.

Etymology.

From “Araripe”, the name of the sedimentary basin to which the Crato Formation belongs.

Comments.

The new genus differs from other Cretaceous Tabanidae by the swelled tibia, the R4 strongly curved to the wing base, and the unusually long abdomen.
