dermopteran
Extremely Low (Specialist/Biological)Highly Technical/Scientific (Zoology, Biology, Paleontology)
Definition
Meaning
A mammal belonging to the order Dermoptera, consisting of the colugos or flying lemurs, which are gliding mammals native to Southeast Asia.
Referring to the biological characteristics, evolutionary lineage, or anatomical features (particularly the patagium, or gliding membrane) of the colugo.
Linguistics
Semantic Notes
The term is almost exclusively used in taxonomic and anatomical contexts. It is not a synonym for 'bat' (Chiroptera) or 'flying squirrel' (rodent). The common name 'flying lemur' is a misnomer, as they are not lemurs and do not fly but glide.
Dialectal Variation
British vs American Usage
Differences
No significant difference in usage. Both variants use the term strictly within scientific literature.
Connotations
Purely denotative, scientific. Carries no cultural or colloquial connotations in either variant.
Frequency
Virtually absent from general discourse in both regions. Frequency is identical and confined to academic texts.

Examples
By Part of Speech
noun
British English
- The Sunda colugo is the most well-known dermopteran.
- The dermopteran's patagium stretches from its neck to the tips of its digits and tail.
American English
- Dermopteran fossils are crucial for understanding early mammal evolution.
- Researchers captured the dermopteran using a high-canopy net.
Examples
By CEFR Level
- The documentary featured a segment on the dermopteran, a gliding mammal from Southeast Asia.
- Phylogenetic analysis suggests that dermopterans are the closest living relatives of primates.
- The dermopteran's extensive patagium allows for remarkably controlled glides between forest trees.
Learning
Memory Aids
Mnemonic
Think: DERMatology (skin) + pTERANodon (winged). A dermopteran has a 'skin-wing' (the patagium for gliding).
Conceptual Metaphor
N/A. The term is a precise scientific label.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid calquing as 'кожекрыл' – the standard Russian term is 'шерстокрыл' (sherstokryl) or 'кагуан' (kaguan).
Common Mistakes
- Confusing it with bats (Chiroptera).
- Using 'flying lemur' as a direct synonym without noting the misnomer.
- Assuming it is a primate (it is in the sister group to primates).

FAQ
Frequently Asked Questions
No. The common name 'flying lemur' is misleading. Dermopterans (colugos) are not lemurs; they belong to a separate order (Dermoptera) and are not primates, though they are a sister group to primates.
No. They are gliders, not powered fliers. They have a large patagium (skin membrane) that allows them to glide significant distances between trees in their forest habitat.
They are native to the tropical rainforests of Southeast Asia, including parts of the Philippines, Malaysia, Indonesia, Thailand, and Singapore.
There are two extant (living) species: the Sunda flying lemur (Galeopterus variegatus) and the Philippine flying lemur (Cynocephalus volans).
