Tuco-tucos, Ctenomys spp.,
are small South American Rodents which live their entire lives underground
within underground burrow systems, never venturing to the surface. Studies of
other Rodents with similar lifestyles, such as the Pocket Gophers of North
America, have found that their burrows tend to form unique ecosystems with
distinctive faunas of Insects and other small invertebrates.
In a paper published in the journal Zootaxa on 8 April 2015,
François Génier of the Canadian National Collection of Insects, Arachnids andNematodes at Agriculture and Agri-Food Canada, describes a new species of
Scarab Beetle discovered during an investigation into the fauna of Tuco-tuco
burrows at low elevation in Santa Cruz de la Sierra province, Bolivia.
The new Beetle is placed in the genus Ctenomys, and given the specific name cujuchi, a local name for Tuco-tucos. These are glossy black Scarab
Beetles 4.3-6.0 mm in length, with coarsely punctate pygidia (dense patterns of
pits on their backs between the heads and wings).
