Hymenoepimecis Viereck, 1912 is a moderately large genus of spider-attacking Darwin wasps. It is confined to the New World where it occurs from Mexico and Central America to Southern Brazil (
The species of Hymenoepimecis are known to be koinobiont ectoparasitoids attacking sub-adult and adult orb-web-spinning spiders belonging to the families Araneidae and Tetragnathidae (summarised in
Currently, there are 20 described species in the genus (
The specimens studied in this work are deposited at the Florida State Collection of Arthropods (
Specimens were examined with an Olympus SZ61 and SZX10 stereomicroscopes and measurements were made through a millimetre ocular. Digital layer images were taken using a Canon DS126461 digital camera attached to an Olympus SZX16 stereomicroscope and combined by using the software Zerene Stacker (Version 1.04 Build T201706041920). Drawings were vectorized digitally using Adobe Illustrator.
