QUITO, Jan 6, 2023 (BSS/AFP) - Scientists have discovered a new species
of dwarf boa in the Ecuadoran Amazon and named it after an Indigenous activist.

Up to 20 centimeters (7.8 inches) long and with skin coloring similar to
those of the boa constrictor -- the previously unknown snake was named
Tropidophis cacuangoae.

The second part of the name honors early 20th century Indigenous rights
activist Dolores Cacuango, according to Ecuador's environment ministry.

Two specimens were found in the Colonso Chalupas national reserve and in the
private Sumak Kawsay park, the discoverers reported.

These snakes "are a relic of time, they are animals so old that finding or
bumping into one of them is a privilege," Ecuadoran researcher Mario Yanez of
the National Biodiversity Institute (INABIO) told AFP.

The species is unusual for having a "vestigial pelvis" characteristic of
primitive snakes and taken as evidence by some that snakes descended from
lizards that lost their limbs over millions of years.

The team's findings were published in the European Journal of Taxonomy.

The ministry said the discovery brought to six the number of known
Tropidophis species, endemic to South America.
