Summary. – The Brown Wood Turtle, Rhinoclemmys annulata (family Geoemydidae, subfamily Rhinoclemmydinae), is a medium-sized turtle (maximum straightline carapace length [SCL] to 226 mm), that is largely terrestrial and primarily occurs in rainforest areas in Caribbean drainages of Central America from Honduras to northern Colombia, and in Pacific drainages from eastern Panama south to Ecuador. In Ecuador, the species occurs in dry forest areas as well. The known elevational range is from sea level to 920 m. The species is monotypic, without subspecies, and demonstrates substantial variability in carapace coloration within populations. There is modest sexual size dimorphism, with males reaching a maximum SCL of 202 mm, and females up to 226 mm. Females lay one large elongate egg measuring approximately 71 x 37 mm and 48–49 g, with a mean hatchling SCL of 63.9 mm. The ecology of R. annulata is poorly studied, and its population status is unknown. The greatest threat faced by this species is habitat destruction, although the degree and impact of this threat remains unknown. It is also sometimes utilized as a local pet and food source by several indigenous and rural populations. Trade into the international pet market appears to be minimal. The species has been recorded from several protected areas within its range, but assessments of its threats, conservation status, and population trends are needed.

Distribution. – Colombia, Costa Rica, Ecuador, Honduras, Nicaragua, and Panama.
