Tortopsis parishi (Banks) New combination

Campsurus parishi Banks 1918: 10 . Tortopus parishi ; Ulmer 1942: 110.

Material: the only specimen known (male holotype) is deposited at Harvard. In spite of the attempts to borrow the material, neither the specimen nor photographs were available for study.

Discussion and diagnosis. This species is known from one male imago from Ecuador (Durar). The original description and figures are inadequate to species characterization but clearly indicate that this species belongs to Tortopsis , as is recovered in the phylogenetic tree ( Fig. 1A ). The main feature used to assign the species to Tortopsis is the form of the penes, widely separated from each other from their bases. Fore wing length is reported to be 10–12 mm ( Banks 1918).

Figures

FIGURE 1. A, strict consensus of 234 shortest trees obtained with the complete data set (58 steps, Ci = 81, Ri = 93); B, strict consensus of 3 shortest trees obtained with the reduced data set (58 steps, Ci = 81, Ri = 92). Values near nodes indicate group support (frequency difference / absolute Bremer Support / relative BS). Black circles indicate unique apomorphies, white circles indicate parallelism or reversal, the small numbers above and below these marks are character and state numbers respectively.
