Paroedura neglecta is a species of lizard in the family Gekkonidae. It was first discovered in 2006, but the species was not named until 2019, hence the specific name meaning "neglected". It is endemic to Tsingy de Bemaraha National Park in northwestern Madagascar.[1]

Taxonomy

The holotype specimen of Paroedura neglecta is an adult male collected on 1 April 2006 from Andafiabe at the Beboka River, in the Melaky region of western Madagascar. Although the specimen was recognized as an unnamed species shortly after its discovery, it was not described until 13 years later in May 2019, thus it was given the specific name neglecta (Latin for "neglected").[2]

Genetic analysis has found that Paroedura neglecta is a member of the

Paroedura bastardi clade, and is a sister taxon to Paroedura tanjaka. The following cladogram shows the position of P. neglecta among its closest relatives according to Piccoli et al. (2023):[3]

Distribution and habitat

This gecko is currently known from only two localities, both within

P. homalorhina, P. tanjaka, P. karstophila, P. spelaea and P. stumpffi.[4]

Description

All collected specimens of Paroedura neglecta were found at night, indicating this species is mostly or entirely nocturnal. The holotype individual has a snout–vent length of 61.3 mm, with a triangular head measuring 20.8 mm long, 14.6 mm wide and 9.2 mm tall. The head is wider than the neck and body, with a vertical slit as the ear opening. The rostral scale is rectangular in shape, much wider than it is tall, and makes contact with the nostril.[2]

Enlarged tuberculate scales are present on the dorsal surface and arranged in longitudinal rows. The dorsal scales of the front limbs are mostly flat, whereas those of the hind limbs are mainly keeled and tuberculate. Each digit is widened at the tip, with a downward-curving claw between the terminal pads. The tail similarly has primarily tuberculate scales.[2]

The dorsal colors are mainly reddish-brown, with reticulated patterns on the head and regularly-spaced light crossbands on the torso. The iris is a golden color, with a reddish area surrounding the pupil and a vessel running down the posterior of the iris, visible as a red-brown stripe. Slightly marbled grey and beige patterns are present on the limbs. The underside of this lizard is whitish with a fine grey shade.[2]

Conservation

Due to limited available data, it has been recommended that Paroedura neglecta be listed as

IUCN guidelines.[2] Both localities the species is known from have only had little anthropogenic disturbance, however nearby areas within Tsingy de Bemaraha National Park have been subject to severe cattle browsing and logging. Due to its restricted range, this lizard could become threatened by the impacts of farming, fire and logging which lead to habitat loss.[5]
