Description of a black fly of the subgenus Simulium (Pternaspatha) from the high Andes of Ecuador (Diptera, Simuliidae). American Museum novitates ; no. 2670

Abstract

"Simulium cotopaxi, new species, collected between 3500 and 4400 meters in the Ecuadorian Andes is described. It shares many derived characters with members of the nemorale group of Simulium (Pternaspatha), but differs by the unique pattern of the scutum of the female and the posteriorly emarginated paraproct, as well as by the extraordinarily enlarged scapus and pedicellus of the antenna of the male. The new species was found more than 1000 km. norh of the previously known northern limit of the subgenus"--p. [1].
