 We describe a new species of the genus Caecilia from French Guiana. The new species differs from most species of the genus in the numbers of primary and secondary grooves. Color pattern, body shape, presence of subdermal scales, and number of teeth separate Caecilia museugoeldi sp. nov. from the other species of the genus. This new taxon is the first of the genus described in 33 years.

Etymology The name of the species is in honor of the Museu Paraense Emílio Goeldi, Belém, Pará, Brazil and is a noun in apposition. The Museu Goeldi is an institution which was established 151 years ago and is the oldest scientific institution in Brazilian Amazonia, which has steadily promoted studies of biodiversity, zoology, botany, archeology, geology, paleontology, hydrology, anthropology, ethnology, podology and linguistics of the area. Despite its important role in obtaining and dispersing knowledge about the biodiversity of the Amazonian basin in its broadest sense, the museum has recently been confronted with serious budgetary problems that should be solved for the long term in an acceptable way by the ministry that is responsible for the museum.  

Ecological observations In the same area where the specimen was collected, two other species of Gymnophiona were obtained as well, viz., Caecilia tentaculata and Rhinatrema bivittatum (Guerin-Menéville, 1838). All specimens were found crossing the road through rainforest at night.
