Etymology.

The generic name Pteropilosa is composed of two parts. The first being Ptero-, which is derived from the old-Greek “pteryx”, meaning “wing”; the last letters -pilosa are derived from the Latin “capillosus”, meaning “hairy” . It can be roughly translated as "hairy wings", referring to the most striking unique feature of this new genus. The generic name is feminine in gender.
