|Scientific Name:||Rhinoclemmys rubida|
|Species Authority:||(Cope, 1870)|
Chelopus rubidus Cope, 1870
Geoemyda rubida subspecies perixantha Mosimann & Rabb, 1953
Rhinoclemmys mexicana Gray, 1870
|Taxonomic Notes:||Two subspecies are recognised: R. r. rubida (Cope, 1869), and R. r. perixantha (Mosimann & Rabb, 1953), defined on head pattern, marginal flare and geographic separation. These taxa may be elevated to species level in the future.|
|Red List Category & Criteria:||Near Threatened ver 3.1|

Very limited status data is available, and suggests long-term natural decline probably accelerated by human impacts. Limited data do not allow quantification of decline to meet criteria A or C for Vulnerable.
|Range Description:||Mexico, on Pacific versant: R. rubida rubida in Oaxaca and Chiapas, R. rubida perixantha in Jalisco, Colima, Michoacan, and Balsas de Morelos, Mexico (Iverson 1992). Possibly extends into western Pacific Guatemala. Occurs from sea level to 1,350 m (Peterson et al. 2004).|

|Population:||Smith and Smith (1979) refer to 'apparent rarity of individuals'. Seen occasionally, including two in one week in Oaxaca and one in Chiapas during August 2005. The species is universally considered as occasionally to rarely encountered.|
|Habitat and Ecology:||
R. rubida inhabits tropical semi-deciduous lowland areas, where they have been recorded from rocky hillsides, near streams in lowland scrub forest, from coastal woodlands, from thorn scrub; and from the ecotone between dry forest and pine-oak forest (Mosimann and Rabb 1953, Peterson et al. 2004). Also in moist mid-elevation habitat. Seen once near pastures, but tolerance to disturbance not completely understood.
Presumably feeds mainly on fruits and vegetation shoots, with opportunistic consumption of animal matter (Carr CBFT Manuscript).
Apparently active mainly or only during the June-November wet season (Iverson in Groombridge 1982).
Maximum size up to 23.0 cm CL in males, 17.9 cm in females (Ernst in Smith and Smith 1979).
No reproductive data are available.
|Major Threat(s):||Smith and Smith (1979) speculated that the currently widely discontinuous distribution indicates progressive reduction of the species' range through natural processes. No specific threats seem to have been documented, though habitat loss from agriculture and infrastructure development and direct exploitation for pets and possibly food, and increased predation by subsidised predators may be factors. Human consumption of the species has not been recorded.|
Turtles in general are protected from exploitation under Mexican wildlife and natural resource legislation; implementation is uneven and in places better enforcement may be needed.
R. rubida perixantha is confirmed to occur in the Chamela Cuixmala Biosphere Reserve (Jalisco; 131 sq. km, core 82 sq. km, cat Ia/VI) and the La Sepultura Biosphere Reserve.
R. r. rubida may occur in Huatulco NP (Oaxaca, MX, 119 sq. km, cat.II), La Sepultura BR (1673 sq. km., cat.VI) and Playa de Escobilla.
Very few animals are kept and bred in captivity, although a facility in Oaxaca is believed to be highly successful breeding the species (Iverson in litt. 28 Jan 2007).
Occurrence and population status needs to be documented better, and monitoring of selected populations would be highly desirable. Data on exploitation, habitat loss and other threats, as well as basic natural history information, are needed.
