Friday mystery object #443 answer

Last week I gave you this cute little fuzzball to have a go at identifying:

Everyone spotted that this is one of the New World porcupines (AKA the Erethizontidae), but there are 18 species to choose from. Some have quite short hairs between their quills, giving a spiky appearance, but this specimen has definite floof. The tail is quite short and the body is small – as several people noticed in the comments.

With a relatively small number of species, and with a few distinctive features to look for, you might expect that scanning through images of the various different species could help get an identification. It turns out that this method worked a bit too well, since this very specimen happens to be used for the image used to depict the species on Wikipedia – as spotted by Allen Hazen.

This mystery object is a Brown Hairy Dwarf Porcupine Coendou vestitus, Thomas, 1899. The reason our specimen has been used to depict the species is probably because there are very few other images of this animal dead or alive – which suggests that it’s probably rather rare (apparently nobody recorded seeing one for over 75 years).

This specimen has a few question marks for me – in particular the collection locality, which is listed as Chiriqui, Central America. This doesn’t sound right, considering the species is considered endemic to the Eastern Cordillera in the Colombian Andes – over 1,000km away. It’s probably down to a data mix up, but if not, it raises some interesting questions.

  1. Check the locality information for our greater anteater in our database, it could be related. I resolved the anteater with the help of Dr Google which led me to a Smithsonian catalog entry that revealed all when a scruffy label on the skull (boxed, not in the mount) was located
