IPA: /ˈtɒpəˌtaɪp/
KK: /tɑːpəˌtaɪp/
A specimen of an organism collected from the specific location where that species was first identified.
The scientist studied the topotype to understand the species' characteristics better.
Topotype is formed from "topo-" (from Greek "topos", meaning place) and "type" (from Greek "typos", meaning impression or model). The word refers to a type or model that is specific to a particular place.
Think of 'topo-' meaning 'place' and 'type' meaning 'model' — together they describe a model that is specific to a certain place.
