Final answer:
Lemurs and lorises are placed in the Strepsirrhini suborder, while tarsiers belong to their own category under the Haplorhini suborder within the taxonomic system of primates.
Step-by-step explanation:
In the proposed revision of the taxonomic system for primates, lemurs and lorises would be placed within the Strepsirrhini suborder, also known as the wet-nosed primates. This group includes the bush babies and pottos of Africa, and the lemurs of Madagascar. In contrast, tarsiers present a more complex classification due to their blend of prosimian and anthropoid characteristics. Although they share some traits with Strepsirrhines, tarsiers are classified within their own category under the Haplorrhini suborder, alongside other dry-nosed primates like New World monkeys, Old World monkeys, apes, and humans.
This taxonomic arrangement recognizes the distinct evolutionary paths and anatomical differences between these groups of primates. For instance, Strepsirrhini primates tend to be nocturnal, possess a smaller brain size relative to body size, and have a characteristic grooming claw. In contrast, Haplorrhini primates, including tarsiers, are mostly diurnal and rely more on vision. A notable difference is that Strepsirrhines can produce vitamin C, while Haplorhines must obtain it from their diet.
