World distribution. Chile.

Chileand distribution. Only recorded from Robinson Crusoe, Juan Fernández Islands ( Fig. 117View FIGURE 117).

Altitudinal range. This species inhabits native forests in ravines and clifttops between 100 and 600 m. a.s.l.

Biology and notes. Sterphus aurifrons  is associated with native vegetation of the Robinson Crusoe in Juan Fernández Islands. This species was assessed in the local red list of threatened species of the Environmental Ministry of Chile under IUCN criteria (CR B1abiii + 2abiii) (www.mma.gob.cl/clasificacionespecies), and was cataloged as threatened due to deforestation and invasive species such as goats Capra hircus (Linnaeus)  , austral thrushes Turdus falcklandii magellanicus (King)  and coatis Nasua nasua (Linnaeus)  . These species affect S. aurifrons  in different ways. Goats invade the forests and trample leaf litter and dead wood where larvae probably develop. The coati is a generalist predator that searches the forest floors for invertebrates to feed on and climbs trees in search of other prey. Thrushes are omnivorous introduced birds that attack insects in semi-urban areas (CONAF, pers. comm.). Etcheverry (1963) recorded the species in Angol, however, it be a labeling error because all other specimens collected are from the Robinson Crusoe Island.

Conservation status. CR under B1ab (iii) + 2ab (iii); AOO = 12 km 2; EOO = 12 km 2 and one locality (or subpopulation).
