Actias uljanae, China: Hunan: Nanling Mountains
Actias chrisbrechlinae, China: Yunnan; Guangxi; 1950-2460m
Actias winbrechlini, China: northwestern Yunnan: Fengshuining Mountains (2460m), Yulong County; northern Myanmar = Burma: Kachin: Chudu Mountains (3000m)

The pronunciation of scientific names is troublesome for many. The "suggestion" at the top of the page is merely a suggestion. It is based on commonly accepted English pronunciation of Greek names and/or some fairly well accepted "rules" for latinized scientific names.

The suggested pronunciations, on this page and on other pages, are primarily put forward to assist those who hear with internal ears as they read.

There are many collectors from different countries whose intonations and accents would be different.

The species name "rasa" is honourific for Rasa Saldaitis.

The genus name, Actias, probably comes from the Greek Actaeon, who is the hunter who had the misfortune of being torn to pieces by his own dogs after accidentally encountering the naked goddess Artemis. To punish him, Artemis splashed water on Actaeon and turned him into a stag. There is an Asian species named Actias artemis.
