Paroedura manongavato
Proposed Critically Endangered·Not specified in text (assumed oviparous for geckos)
Paroedura manongavato is a reptile species of gecko recently identified in 2023, distinguished from its previously assigned classification as Paroedura bastardi through genetic and morphological analysis. This microendemic species is found exclusively in two specific locations in Madagascar, Tsaranoro Valley Forest and Anja Reserve, inhabiting semi-arid deciduous forests. It is characterized by its ochre and light brown coloration with darker markings, keeled scales, and a preference for granitic boulders.

About Paroedura manongavato
Paroedura manongavato: A Newly Identified Gecko of Madagascar
Paroedura manongavato is a species of lizard belonging to the Gekkonidae family, recently identified as distinct in 2023. Previously, specimens were classified under the broader category of Paroedura bastardi. This gecko is notable for being microendemic, meaning its natural range is extremely restricted, currently known only from two specific locations in Madagascar: the Anja Reserve and the Tsaranoro Valley Forest. These areas are characterized by semi-arid deciduous forest environments.
Physical Characteristics and Habitat
The physical description of Paroedura manongavato includes ochre and light brown background colors adorned with contrasting darker brown markings across its body. It possesses prominent keeled scales arranged in regular longitudinal rows on its back and tail, which is also spiny. The limbs share similar keeled scales, and its digits are equipped with expanded tips, downward-curving claws, and adhesive pads, adaptations common in geckos for climbing. Juveniles exhibit three broad light crossbands on their dorsal side. The species shows a strong affinity for granitic boulders, often observed on or near them, and appears to prefer the humid microhabitats found within the cavities and caves formed by these rock formations.
Behavior and Conservation
Paroedura manongavato is active during both diurnal and nocturnal periods. It is a terrestrial species that actively climbs the granitic boulders within its habitat. When threatened or startled, it has been observed to jump from its perch onto the leaf litter below, suggesting a potential defensive behavior. Despite living in semi-arid forests, the preference for humid boulder cavities highlights a specialized ecological niche. Genetically, it appears reproductively isolated from other closely related species found in the same localities, possibly due to differences in substrate utilization. Due to its extremely limited distribution and the severe fragmentation and decline of its habitat, primarily caused by deforestation and human land-use changes, Paroedura manongavato has been proposed for listing as Critically Endangered under the IUCN Red List guidelines. Conservation efforts focused on protecting the Anja Reserve and Tsaranoro areas, managed by local communities, are considered essential for the survival of this and other microendemic species.

Frequently Asked Questions
When was Paroedura manongavato recognized as a separate species?
Paroedura manongavato was formally described and recognized as a distinct species in 2023. Prior to this, specimens were often grouped with or considered similar to Paroedura bastardi. The distinction was made based on genetic and morphological data.
Where is Paroedura manongavato found?
This gecko is microendemic, meaning it is found in a very small, specific geographic area. Its known distribution is limited to two locations on the south-central plateau of Madagascar: the Tsaranoro Valley Forest and the Anja Reserve.
What kind of habitat does Paroedura manongavato prefer?
Paroedura manongavato inhabits semi-arid deciduous forests. It shows a strong association with large granitic boulders, often being observed on them or in cavities beneath them. This suggests a preference for rocky environments within these forest types.
What are the physical characteristics of Paroedura manongavato?
Adults have a snout-to-vent length of around 68.3 mm. They feature ochre and light brown background colors with darker brown markings. Prominent keeled scales are present on the body and tail, and their digits have expanded tips with claws and adhesive pads.
What is the conservation status of Paroedura manongavato?
It has been proposed that Paroedura manongavato be listed as Critically Endangered on the IUCN Red List. This recommendation is due to its very limited range and the ongoing decline and fragmentation of its habitat.
What are the primary threats to Paroedura manongavato?
The primary threats are severe deforestation and habitat fragmentation caused by human activities such as slash-and-burn agriculture, the construction of roads, and settlements. These activities have drastically altered the landscape and impact the gecko's specialized habitat.

Ablepharus
Ablepharus, commonly known as snake-eyed skinks, are small lizards distinguished by fused eyelids that prevent blinking, similar to snakes. They inhabit dry fields, hills, and rocky areas, often concealed within leaf litter. These skinks possess shiny, bronze scales and a characteristic dark stripe along their sides, feeding primarily on small insects and mollusks.
Agama agama
The common agama, also known as the red-headed rock agama, is a widespread lizard species native to sub-Saharan Africa and introduced to Florida. It is characterized by its distinct coloration, with males exhibiting blue bodies and yellow tails, while females and subordinates have olive green heads. These lizards are diurnal, territorial, and primarily insectivorous, playing an important role in their ecosystems.
Agama bibronii
Agama bibronii, commonly known as Bibron's agama or the North African rock agama, is a medium-sized lizard native to northwestern Africa. This species inhabits rocky areas and is characterized by its greyish-green coloration with brown spots, and distinct blue heads in males. They are diurnal, omnivorous, and play dead when threatened.
