Cisticolidae, Cisticolas (pronounced sis-TIC-olas): from Ancient Greek kisthos, "rock-rose", 
"kisthos" (κίσθος) means "basket" or "box," referring to the shape of the fruit (capsule) of the Cistus plant, commonly known as rockrose, which holds its seeds. The genus name Cistus comes directly from this Greek word. 
Latin colere, "to dwell".
The species name atrogularis is a combination of Latin ater (meaning "black") and gularis, meaning "-throated" (from gula, meaning "throat").
