Tullgrenella peniaflorensis Galiano, 1970: 29 , 342–344, figs 50–1, 56; Galiano and Maury, 1979: 313.

Type material: Holotype: ♀, Peñaflor , Chile, 70.92°W, 33.62°S, February 1958, M. Toro ( BJR853 , MACN 6242 ) .

Abdomen tan, covered with short brown, reflective hairs and scattered longer black hairs and with a grey-brown border on the anterior half, two longitudinal lines of five pairs of small patches made up of grey hairs on the posterior half.
