Range DescriptionAglaeactis aliciae is only known with certainty from a tiny area in the upper Marañón drainage of La Libertad, west Peru (F. Angulo Pratolongo in litt. 2012). Though there were historical records from Succha and nearby Soquián in La Libertad, the only location that produced regular records in the period 1979-2005 was El Molino, also in La Libertad (J. Hornbuckle in litt. 1999, Hunnybun 1999, T. S. Schulenberg in litt. 1999, Lambert and Angulo 2007), where (at least until 2003) the species was described as "locally common" (D. Geale in litt. 2005, Lambert and Angulo 2007), although available habitat at this site covers less than 1 km2. However, in 2006 field surveys found the species to be widespread and locally common within its reported historical range on the east bank of the Marañón, and, indeed, elsewhere (e.g. on the west bank of the Marañón and in the upper Chusgon Valley). The distance between the most northerly and southerly points where the species was found was 35.5 km (Lambert and Angulo 2007). There is also an unconfirmed sighting from the Llanganuco area in Ancash (Fjeldså and Kessler 1996), c.140 km south of the La Libertad sites; and within the Chusgón Valley, there is an additional area of 155 km2 within which the species could potentially occur (Lambert and Angulo 2007).
