inner pleural appendage with the caudal margin fringed with

 ventro-median area membranous. Eighth sternite with a 

 very small median lobe (plate 2, fig. 16) that is sparsely 

 provided with påle hairs. Female ovipositor (plate 2, fig. 20) 

 with the dorsal basal shield a little longer than the tergal 

 valves; these latter are straight with the tips acute; sternal 

 valves very long and flattened, extending almost to the ends 

 of the tergal valves, their tips acute.

This species agrees fairly with Bigot's discription of 

 Tipula variineura (as Nephrotoma) but this species has the 

 antennal segments of the male more slender and attenuated, 

 and the ovipositor of the female short and conoidal. 



The specific name, tehuelche, is derived from that of the 

 Indian tribe of this name inhabiting eastern Patagonia, south 

 to the Straits of Magellan (see Hatcher, Reports of the 

 Princeton University Expedition to Patagonia, 1896—1899, 

 vol. 1, Narrative and Geography, pp. 261 — 272; 1903).

 dark brown, the terminal abdominal segments brownish
