Diagnosis and Specialized Morphology
Species of Sphaeridopinae are characterized by:
- head slightly projecting beyond anterior margin of compound eyes
- compound eyes large and nearly contiguous ventrally
- antennae inserted on anteriorly projecting tubercules
- labium straight
- 3-segmented tarsi
Taxonomic history for this subfamily is being reviewed.
The Sphaeridopinae is a Neotropical subfamily that is comprised of four genera. Pinto (1927) believed that species fed on vertebrate blood based on the structure of the labium. However, according to Schuh & Slater (1995), there appears to be no direct evidence of vertebrate blood-feeding.
