False Cienega Colorado Worm Salamander
© 2010 Division of Herpetology, University of Kansas (1 of 1)
Description: O. pseudouniformis is a member of the uniformis group and has many similarities. The snout-vent length of this salamander is 50.2 mm. It has 19-20 coastal grooves per side and 23 left and 23 right maxillary teeth. It also has 8 left and 9 right vomerine teeth. The mental gland can be seen as two triangle patches on the chin. The nostril, labial protuberances and snout are small. A postorbital groove extends from the eye and across the gular area. The tail is thick, compressed laterally and has a mild constriction at the base. Limbs are long and the fingers and toes are thick. The toes are partially webbed (Brame 1968).
Coloration: This salamander is jet black dorsally, with faint orange dorsal patches and light grey-black ventrally. A pale white region is present anterior to the gular fold. Black coloration surrounds the vent. The upper lip is light colored, but the lower is lined with dark coloration. The limbs are brown-purple (Brame 1968).
Variation: There is variation found in size between individuals of different places (Brame 1968).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Costa Rica, Nicaragua
Life History, Abundance, Activity, and Special Behaviors
Like other members of the uniformis group, this species has an easily detachable tail and displays a flipping behavior, supposedly to ward off predators or escape their grasp (Smits and Brodie Jr. 1995).
Trends and Threats
Possible reasons for amphibian decline
Habitat modification from deforestation, or logging related activities

O. pseudouniformis was first described in 1968 by Arden Brame.
This species is placed in the uniformis group (Brame 1968; McCranie et al. 2008). It is most closely related to O. cyclocauda (García-París et al. 2000).
