Leucotrichia alisensis Rueda Martin, 2011 Fig. 6

alisensis Rueda Martín, 2011: 4 [Type locality: Argentina, Tucamán, Parque Nacional Campo de Los Alisos, Río de las Pavas; IML; male metamorphotype; larva, pupa].

Diagnosis.

Leucotrichia alisensis is similar to Leucotrichia yungarum ; in each, the ventral arm of the subgenital plate is acute in lateral view and the apex of the inferior appendage is digitate in ventral view. Additionally, the shape of the inferior appendage in lateral view is similar in both species, particularly the rounded basal area. Leucotrichia alisensis can be recognized by the V-shaped concave posterior margin of sternum VIII, which is U-shaped in Leucotrichia yungarum , and by the curved anterolateral projection which is absent in Leucotrichia yungarum .
