strepsirhini
Definition
Noun A taxonomic suborder of primates that, in some classifications, is either exactly equivalent to the superfamily Lemuroidea or includes the "true lemurs." This group is characterized by features such as a moist rhinarium (wet nose), a toothcomb, and often nocturnal habits, distinguishing them from other primates like monkeys and apes.
Usage
The term is used in scientific and zoological contexts to classify a specific lineage of primates. * The Strepsirhini are considered more primitive in some anatomical features compared to anthropoids. * Biological classification places lemurs and lorises within the suborder Strepsirhini.
Advanced Usage
- The suborder Strepsirhini is contrasted with the suborder Haplorhini, which includes tarsiers, monkeys, and apes. This division is based on significant morphological and genetic differences.
- In some taxonomic systems, Strepsirhini is synonymous with the infraorder Lemuriformes.
Variants and Related Words
- Strepsirrhine (adjective/noun): The alternative spelling and the adjectival form used to describe characteristics of or belonging to this suborder.
- The researcher studied strepsirrhine locomotion.
- Lemuroidea (noun): The superfamily often considered coextensive with or a core part of Strepsirhini.
Synonyms
- Prosimians (in traditional, paraphyletic classifications; note that "prosimian" often included tarsiers, which are now classified separately under Haplorhini).
Noun
-
in some classifications either coextensive with the Lemuroidea or comprising the true lemurs
