Leptotarsus (Longurio) byersi, a new flightless crane fly from Ecuador (Diptera: Tipulidae)

Abstract:

A new genus and species of flightless crane fly, Leptotarsus (Longurio) byersi Young and Gelhaus is described and illustrated for both sexes. This is the first record of a flightless species of Leptotarsus for South America, and one of the few Neotropical species of Tipulinae subapterous in both sexes. The closest relative to Leptotarsus byersi is L. stenostyle ALEXANDER, also from Ecuador but with fully winged males. Leptotarsus byersi shows modifications in both the thorax and coxae, in addition to the reduction of wings. All specimens were collected with pan traps.
