Despite the relatively small distance of this new record from the town of Puruchuco—the closest known population (Icochea and Cossios, 2006)—we consider this new record to be a distinct population because there are effective barriers (runways, buildings, etc.) that likely prevent individuals from dispersing between the localities. Documenting this new population is important because of the few known remaining populations of P. sentosus and the serious threats that this species faces.Asociación Herpetológica Argentin

Comments.—  Distribution of the critically endan-
gered gecko Phyllodactylus sentosus is restricted 
to the city of Lima, Perú; where it is known from 
just five small populations (Dixon and Huey, 1970; 
Icochea and Cossios, 2006; Pérez, 2009).  The natu-
ral habitat of this gecko is Coastal Desert  in areas 
with sustrate dry soil or sand with some rocks and 
without vegetation.  Currently this kind of habitat 
is restricted to a few localities in the city of Lima. 
Phyllodactylus sentosus has a low reproductive rate 
(Dixon & Huey, 1970) and poor dispersal ability. 
These characteristics, coupled with negative impacts 
from human activities in the city of Lima, have 
resulted in the severe destruction of their habitats 
(Icochea, 1998), greatly reducing the chances of the 
persistence of P. sentosus. Consequently, P. sentosus 
is the only coastal reptile identified as Critically En-
dangered in the current Peruvian Wildlife Red List 
from the National Institute of Natural Resources of 
Ministry of Agriculture INRENA (Supreme Decree 
No. 034-2004-AG).
This new record for the city of Lima extends 
the distribution of P. sentosus 4.5 km (straight line) 
to the northeast. An unvouchered juvenile was also 
recorded at this locality in February 2007 (José 
Pérez, pers. observ.). These two records confirm 
the presence of the species in the area. Despite the 
relatively small distance of this new record from the
