Allocladius quadrus Andersen, Saether et Mendes

( Fig. 33 G–I )

Allocladius quadrus Andersen, Saether et Mendes, 2010: 17 .

Material examined: CHILE: Región XII, Punta Arenas, Lago El Pamilar, 53º24.444’S, 71º15.823’W. 246 m a.s.l., holotype male, 10.iii.1998, T. Andersen ( ZMBN Type No. 424). Paratype male, as holotype.

Diagnostic characters: The presence of square single pars ventralis ( Fig. 33 G–I ) much wider than long and without setae together with the tongue-like strongly projecting inferior volsella and the high antennal ratio will separate the species from other species with pars ventralis.

The male is described in detail in Andersen et al. (2010: 17).

Distribution

The species is known from Chile (Andersen et al. 2010).
