Etymology
This species is named after Lucy Cooke, a unique combination of a professionally trained biologist cum television producer–director–presenter, and author of bestselling natural history books; who with wit, perspicacity and wisdom has been bringing before the public the findings of cutting-edge science and demolishing many long-held myths in biology from aspects of the lives of organisms like sloths to the Darwinian view of sexual selection with its inherent Victorian biases. The name is treated as a noun in the genitive case.
Diagnosis
This species is distinct with large (0.5× MOD) uniformly shaped and sized reticulations on T2.
