Type-species: C. rufum Macquart, 1851 (orig. des.).
This genus was originally comprised of C. rufum Macquart, 1851 , described from one male specimen.
Soon after the original description the type-specimen was studied by Bigot (1882) who rectified the original description. McAlpine (1989) reported that the type of Ctenostylum rufum was lost and he described a male from Costa Rica but did not give a name to it. He did not evaluate variation between the two male specimens because Macquart’s description was not very detailed, the illustrations were innacurate and a series of specimens was not available.
Looking for ctenostylid specimens in the Amazon Basin we found one Ctenostylum specimen housed at MPEG. It was collected in Serra Norte, Carajás, Southeastern Pará state, and it appeard to be different from C. rufum according to Macquart’s original description and Bigot’s (1882) rectification, and different from the undescribed male from Costa Rica ( McAlpine 1989). The two previously-known specimens are males and here we describe the first female of this genus. The arista of the female is very complex, with dendritic branching ( Fig. 4 View FIGURES 1 – 7 ), identical to females of other ctenostylid genera. but female tergite and sternite 7 ( Fig. 8 View FIGURES 8 – 12 ) are not fused, as is found in the remainder of the family( McAlpine 1989).
