Trypeta atra Loew, 1862, Berlin Entomol. Zeitsch. 6:210. Holotype o. Type locality: New York.




Size: body 3.0-4.0 mm; wing 2.7-3.0 mm (N=5).

Body color: Abdomen black, the dorsum covered with white setae intermixed with distinct black hairs.

Oviscape: Female ovipositor long, approximately 3.0 mm. Ovipositor sheath black, dorsum covered with numerous black hairs, about 1.5 mm long.  


North America: Kansas to Maine; South to Florida

Florida: Northern Florida: Duval County, Atlantic Beach (Johnson 1895). (This record may refer to P. australis rather than P. atra, as P. australis was not recognized prior to Aldrich (1915). Confirmed records from Bay and Madison Counties.
