A male Vissian.
The Vissians are a humanoid species notable for having three genders. First contact was made by the NX-01 Enterprise in 2153 and generally proceeded well, as Vissians became fast friends with humanity (ENT episode: "Cogenitor").
In 2156, the Vissians denied Jonathan Archer's request that they enter the Earth-Romulan War on Earth's side. (ENT - The Romulan War novel: To Brave the Storm)
At least one Vissian woman served as an engineer in the Federation Starfleet, serving under Captain Montgomery Scott in the S.C.E.. She was berated by him for not completing a report on a Martian time corridor generator fast enough. (SCE eBook: The Future Begins)
