Etymology
The generic name Urotriorchis was coined by Richard Bowdler Sharpe in 1874 and combines "Uro-", from the Greek "tail", and "triorchis", a kind of hawk thought to have three testicles—for further details see Eutriorchis. "Macro-" is from the Greek for "long", so macrourus means "long-tailed", as in the English name.
