With the exception of the tarsiers, all of the prosimians are in the suborder Strepsirhini.
The Strepsirhini clade is composed of seven families split into two groups.
Because they are prosimians, the tarsiers were once classified in the Strepsirhini; they are now grouped in suborder Haplorhini with the monkeys and apes and are the most primitive of the extant haplorhines.

In the Strepsirhini the nostrils are crescentic or comma-shaped, the rhinarium surrounding the nostrils is moist and glandular, and there is a median cleft down the middle of the rhinarium.
Schwartz (1986) argued that Tarsius belongs in the Strepsirhini and thus that Simpson's classification of the Primates into the two suborders Prosimii and Anthropoidea is, after all, the most appropriate.
The living Strepsirhini are sometimes divided into two infraorders: the Lemuriformes, for the Lemuridae, Indriidae, and Daubentoniidae; and the Lorisiformes, for the Lorisidae.

 p-Primates   (Site not responding. Last check: 2007-10-07)
Spec's change in primate evolution, the switch that failed to turn on, occurred some time during the Eocene, still early in the Cenozoic.
At this point in our home timeline, the first primates split into two lineages, the Strepsirhini (which include lemurs and lorises) and the Haplorhini (which include tarsiers and monkeys including apes including humans).
Instead, Spec has the pokemuroids, which are absent from Home-Earth (prompting certain philosophers to ask whether a tree fox is, ultimately, sort of a failed human...

 PRIMATES
Primitively, primate molars were brachydont and tuberculosectorial, but they have become bunodont and quadrate in a number of modern forms.
Living primates are divided into two great groups, the Strepsirhini and the Haplorhini.
We differ, however, in that we place humans and their close relatives, the chimpanzee, gorilla, and orang in the family Hominidae.

 Monkey World -- A World Full of Monkeys
primates are divided into two groups, the Strepsirhini and the Haplorhini.
The Strepsirhini have naked noses, lower incisors forming a toothcomb, and no plate separating orbit from temporal fossa.
The Haplorhini on the hind foot is modified to form a "toilet claw" used in grooming.

 Pokemuroidea   (Site not responding. Last check: 2007-10-07)
Pokemuridae is closest in morphology to the Strepsirhini (lorises and lemurs) of both timelines.
It is therefore no wonder that pokemuroids were originally classified inside p-Strepsirhini, and considered surviving adapiforms.
Both molecular and fossil evidence, however, suggests that Pokemuroidea evolved roughly at the same time as Haplorhini (tarsiers and monkeys including apes) and Strepsirhini split in our timeline.

 Primate Genomics: The Search for Genic Changes that Shaped being Human
The total group includes, in addition to all members of the crown group, the stem of the LCA and all extinct offshoots of the stem.
Thus the age of 63 Ma for the LCA of all living primates – that is, the age for Primates as a crown group – is the age for both Strepsirhini and Haplorhini as total groups.
In turn, the ages of 50 Ma and 58 Ma listed alongside of Strepsirhini and Haplorhini, respectively, are the ages for these two taxa treated as crown groups.
