We estimate habitat loss and fragmentation in a hoverfly, Aneriophora aureorufa, used as a representative forest specialist species. This species is a pollinator specialist of two native trees, forming a triad endemic to the South American Temperate Rainforest (SATR). We combine species distribution models with species-specific requirements to estimate the habitat range of A. aureorufa over two non-overlapping time periods (before human settlement to 2000, and from 2000 to 2014). We analyzed the predicted distribution range of A. aureorufa in Chile, quantifying habitat loss in both periods and fragmentation in the latter. In addition, we evaluated the representativeness of the Chilean protected areas system in relation to the current habitat of the species. We found that the total habitat of A. aureorufa decreased by 68.3% compared to historic pre-settlement levels, in the period 2000-2014 the loss was 4.9%. The northern zone was the most affected by habitat loss and fragmentation, with an estimated total loss of 89.9% from the historic period to 2014, with the loss of 238.2km(2) per year between 2000 and 2014. Eighteen percent of the habitat of A. aureorufa occurs within protected areas. We found an overrepresentation in the southern zone (24.79%) and an underrepresentation in the northern zone (3.44%). We propose that forest specialist species of the northern zone of the SATR could be threatened due to the high pressure of habitat loss and the underrepresentation of the Chilean protected areas systems.
