haplorhine
C2Scientific / Academic
Definition
Meaning
a member of the primate suborder Haplorhini, which includes tarsiers, monkeys, apes, and humans, characterized by a dry nose and complete postorbital closure.
In biological anthropology and primatology, the term classifies primates into one of two major suborders (the other being Strepsirrhini). The grouping reflects significant evolutionary traits related to nasal anatomy, brain development, and reproductive biology.
Linguistics
Semantic Notes
This is a highly specialized taxonomic term. Its meaning is fixed within biological classification and carries no figurative or colloquial use. It is always used as a noun.
Dialectal Variation

Differences
No significant differences in meaning or usage. Spelling is identical. The term is used identically in scientific literature globally.
Connotations
Purely technical and neutral in both varieties.
Frequency
Extremely low frequency in both, restricted to specialist texts in primatology, evolutionary biology, and anthropology.

Examples
By Part of Speech
adjective
British English
- The haplorhine lineage diverged from strepsirrhines millions of years ago.
American English
- Haplorhine primates exhibit a reduced reliance on the sense of smell.
Examples
By CEFR Level
- Monkeys, apes, and humans all belong to a group called haplorhines.
- The key anatomical distinction between haplorhines and strepsirrhines lies in the structure of the nose and the surrounding rhinarium.
Learning
Memory Aids
Mnemonic
Think of 'HAPLO' for 'simple' or 'single' and 'RHINE' for 'nose' – a haplorhine has a simpler, dry nose compared to the wet, complex nose of a strepsirrhine.
Conceptual Metaphor
N/A for highly technical terms.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as "гаплорин". The accepted scientific term in Russian is "гаплориновые" (for the suborder) or "сухоносые обезьяны" (dry-nosed monkeys) as a descriptive term.
- Avoid confusion with "примат" (primate), which is the broader category.
Common Mistakes
- Mispronouncing it as /heɪpləraɪn/. The first syllable is /hæp/.
- Using it as an adjective (e.g., 'haplorhine features' is fine, but 'it is haplorhine' is less common than 'it is a haplorhine').
- Confusing it with 'hominine' or 'hominid'.

FAQ
Frequently Asked Questions
Yes, humans (genus Homo) are classified within the suborder Haplorhini, under the infraorder Anthropoidea (simians).
Haplorhines have dry noses and complete postorbital closure (bone behind the eye), while strepsirrhines have wet, rhinarium-equipped noses and a postorbital bar (not a full plate). Lemurs and lorises are strepsirrhines.
No, it is a very low-frequency, specialist term used almost exclusively in scientific contexts related to primate biology and evolution.
Only in a strictly technical, biological sense (e.g., 'Humans are haplorhine primates'). It is not a descriptive term for personal characteristics and would be nonsensical or humorous if used as such in everyday conversation.
