also hap·lo·rhine  (hăp′plə-rīn′)
Of or belonging to the primate suborder Haplorhini, consisting of the tarsiers, New World monkeys, Old World monkeys, and apes including humans, which characteristically have a dry area between the upper lip and the nostrils.
A haplorrhine primate.

[New Latin Haplorhīnī, suborder name : Greek haplos, simple, single; see sem- in Indo-European roots + Greek rhīs, rhīn-, nose (from the fact that their noses typically have slitlike nostrils and lack the moist area present in strepsirrhines ).]

Most authors, however, currently favor a distinction between strepsirrhines and haplorrhines. Unfortunately, many of the features that enable such division are related to soft anatomy, so that the classification of fossil 'prosimians' as either strepsirrhines or haplorrhines, albeit favored here, is not always straightforward.
A total of 25 primate genera, corresponding to 7 families (one of plesiadapiforms, 2 of strepsirrhines and 4 of haplorrhines), from up to 116 different localities, are reported (27 from the Eocene, 3 from the Oligocene, 32 from the Miocene, 4 from the Pliocene, 51 from the Pleistocene and one with an undetermined age).
