Condor Sticklizard (Pholidobolus condor)

Reptiles of Ecuador | Sauria | Gymnophthalmidae | Pholidobolus | Pholidobolus condor

English common name: Condor Sticklizard.

Spanish common names: Cuilanpalo del Cóndor, cuilán del Cóndor.

Recognition: ♂♂ 11.8 cmMaximum distance from the snout to the tip of the tail. Snout–vent length=4.7 cm..1 Sticklizards differ from other lizards by having short but well-developed limbs, overlapping striated sub-hexagonal dorsal scales, and a brownish dorsal pattern with longitudinal stripes.2,3 The presence of six-sided finely wrinkled dorsal scales distinguishes member of this genus from other co-occurring small brownish lizards such as those in the genera Alopoglossus, Anadia, Andinosaura, Macropholidus, and Riama.4 The Condor Sticklizard (Pholidobolus condor) is the only member of the genus known from its range and is easily differentiated by having green dorsolateral stripes on the head.1 Females of the species are unknown.

Natural history: Extremely rareTotal average number of reported observations per locality less than three.. Pholidobolus condor inhabits a plant formation best described as a well-preserved montane forest and scrub practically without any human intervention.1 Only two adult individuals of the species are known. One was active at night at the base of a bromeliad in the midst of shrub vegetation and the other was moving through moss-covered soil in an open area during a sunny day.1,5 Pholidobolus condor can have communal nests. Four eggs have been recorded under trunks or at the base of bromeliads1,5 up to 170 cm above the ground.5

Conservation: Critically Endangered Considered to be facing imminent risk of extinction..1 Pholidobolus condor has been proposed to be included in this threat category because the species’ known range is extremely restricted and large-scale habitat fragmentation and destruction is evident within a few kilometers of the type locality.1 Although the known population is currently within the limits of the El Quimi Biological Reserve, small and large-scale mining activities are a threat that could extirpate this population.1

Distribution: Pholidobolus condor is endemic to El Quimi Biological Reserve in the Cordillera del Cóndor, Morona Santiago province, southeastern Ecuador.1 The species has been recorded at elevations between 1994 and 2226 m (Fig. 2).

Etymology: The generic name Pholidobolus, which comes from the Greek words pholidos (meaning “scale”) and bolos (meaning “lump”),6 probably refers to the imbricated or mounted scales that are characteristic of the genus. The specific epithet condor refers to Cordillera del Cóndor, the mountain range where the species was discovered.1

See it in the wild: Pholidobolus condor is an extremely rare species, known only from its type locality. With so few individuals reported it is unlikely to observe them in the wild even after several days looking for them. It appears the best way to search for individuals of this species is by scanning bromeliads and low vegetation during hours of sunshine.
