Haplorhini, the haplorhines or the "dry-nosed" primates is a suborder of primates containing the tarsiers and the simians, as sister of the Strepsirrhini ("moist-nosed"). The name is sometimes spelled Haplorrhini. The simians include catarrhines, and the platyrrhines.
Haplorhini. The haplorhines, the "dry-nosed" primates (the Greek name means "simple-nosed"), are members of the Haplorhini clade: the prosimian tarsiers and all of the true simians. The simians are the catarrhines ( Old World monkeys and apes, including humans) and the platyrrhines ( New World monkeys ).
As you no doubt recall, Haplorrhini means “simple nose.” The shared characteristics of tarsiers, New World monkeys, Old World monkeys, and apes include: relatively flattened faces (when compared to Strepsirrhini) forward facing eyes. postorbital enclosure (bony plate encloses back of eye socket) dry noses. decreased reliance on sense of smell.

Our goal in taxonomic classification is to place taxa into categories that reflect their clade relationships. A is a grouping of organisms that reflect a branch of the evolutionary tree, a grouping based on relatedness. Clade relationships are determined using derived traits shared by groups of taxa as well as genetic similarities. An example of a ...
The Order Primates is subdivided into Suborder Strepsirrhini and Suborder Haplorrhini, which, according to molecular estimates, split about 70–80 million years ago (Pozzi et al. 2014). The strepsirrhines include the groups commonly called lemurs, lorises, and galagos (Figure 5.14). Strepsirrhines differ from haplorrhines in many ways, most of which...
When the strepsirrhini and haplorrhini split from one another, strepsirrhines retained more primitive traits (those likely present in the last common ancestor), while haplorrhines became quite different, developing many derived traits. Thus, all of the traits discussed below are considered derived traits. As mentioned earlier, the visual systems of...

Nov 19, 2019 · The main difference between strepsirhines and haplorhines is that strepsirhines make up one of the two suborders of primates, containing wet-nosed primates, whereas haplorhines make up the second suborder, containing dry-nosed primates.
