Aelia Flavia Flaccilla (31 March 356 – 386), was a Roman empress and first wife of the Roman Emperor Theodosius I.

Afraflacilla is a genus of the spider family Salticidae (jumping spiders).
 Most species are distributed in Eastern to Northern Africa (including the Middle East) and Australia, with one species ("A. epiblemoides") found in Europe.
 This genus was for a time included in the genus "Pseudicius", and the boundaries between both genera are disputed.
 In 2016 Jerzy Prószyński erected the genus "Psenuc" for some borderline species.
 The name "Afraflacilla" is combined from Africa, where most earlier described species were found, and "Flacilla" , an obsolete salticid genus now called "Flacillula" .
 This genus name is in turn derived from Aelia Flaccilla, wife of Roman Emperor Theodosius I.
 "Afraflacilla", "Pseudicius", "Festucula" and "Marchena" are close relatives and form a monophyletic group.
Aelia Pulcheria (385–386) was the daughter of Roman Emperor Theodosius I and Roman Empress Aelia Flaccilla.
 This Pulcheria apparently died in childhood, and is not to be confused with her more famous niece of the same name.

 A weak ruler, his reign was dominated by a series of powerful ministers and by his wife, Aelia Eudoxia.
