Comment: The female of this species is flightless.
A similar species, Neocoelidia vittapennis, could also potentially be found in our area. It has a pair of black spots in the basal angles of the scutellum and dark brown longitudinal lines on the venation of the wings, especially the claval suture and costal margin. It occurs along the Gulf Coast and southern Atlantic coast. (DeLong 1953)
A second similar species, Neocoelidia orientalis, has been collected from nearby Tennessee in various locations. It resembles N. tumidifrons in coloration and appearance but is larger (4.0-5.0 mm) and with different male genitalia. The claval and costal wing veins are brown. The female pregenital sternite is long, with the posterior margin truncate. (DeLong 1953) |
