Answer:
The correct answer is - no.
Explanation:
In the Homo habilis and homo neanderthalensis the genus name of both species are the same so and can easily be depicted as an individual without confusion.
The correct abbreviation for Homo habilis is H. habilis and for Homo neanderthalensis is H. neanderthalensis. Both are referring to the same species as indicated by H. which is homo.
Thus, there is no need to change the abbreviation.
