Distribution ( Fig. 1 ). ARGENTINA: Chubut (new record), Santa Cruz. CHILE: I Region de Tarapaca (Arica), IV Region de Coquimbo, Region Metropolitana (Santiago), V Region de Valparaiso.

Comments. This species was recently redescribed by Couri & Penny (2007), and the specimens studied here agree with their description. The biological information on this species is poorly known (see Introduction). The specimens studied here were captured with a hand net on rotten cow meat.

Geographic distribution. The distributions of both species are restricted to Chile and Argentina. Arthurella nudiseta was originally recorded from El Canelo, Santiago, Region Metropolitana, and Algarrobo, Valparaiso, V Region de Valparaiso ( Albuquerque 1954). Later, Lopes (1985) added the northern-most known occurrence in Lluta, Arica, I Region de Tarapaca. More recently, Couri & Penny (2007) registered the first record for Argentina in Piedra Buena and Perito Moreno, Santa Cruz province, and included new records of Hacienda Illapel, Coquimbo, IV Region de Coquimbo, Chile.

The distribution of A. nudiseta includes several locations, all in the Andean Region. On the other hand, A. choelensis was collected in the South American Transition Zone (Monte province) and in the Neotropical Region (Chaco and Pampa provinces) ( Morrone 2006). With this distribution, we could hypothesize that these species are allopatric.
