Sparnia edwardsi Muir, 1927 - Chile (Chiloe Is.)
Sparnia praecellens Stål, 1862 - Brazil, Ecuador, Peru, Venezuela
Sparnia williamsi Muir, 1926 - Ecuador
Sparnia praecellens was reported by Muir (1926) from sugarcane in two locations (Bucay ~1,000 ft elevation; Banos ~6,000 ft elevation), and was listed by Box (1953) as a sugarcane insect.
Sparnia praecellens - reported from sugarcane (Saccharum officinarum L) (Poaceae).
This genus is very distinctive; one of few Delphacini with flattened antennae, but differs from other Delphacini with flattened antennae in having both segments quite long, reaching or exceeding the mesonotum.
Specimens are uncommon in collections, but sometimes found in series (Sparnia praecellens, at least). Probably locally common.
