Panorpa venosa Westwood, 1846
Diagnosis: This species is a member of the rufescens species group with a single basal spot along the costal margin of the forewing, narrow male hypovalves that reach the apex of the basistyles, basal lobe of the dististyles truncated apically and with a row of short spines dorsally. This species is part of the subgroup lacking heavy black spines at the apex of the basistyles. The ventral parameres have a row of stout spines along their mesal margin, but the apical portion is free of spines and the apices approximate each other.
Distribution – Geographical: Coastal Georgia near Savannah.
Distribution – Temporal: 28 April to 20 June.
Ecology: Individuals have been collected in live oak forest and savannah.
Biology: Nothing is known of immature stages or life history.
Notes: The original type series of two females used by Westwood is still in existence in The Natural History Museum, London, and one of these specimens was designated lectotype by Byers (1962). At the time he also felt that these specimens were synonymous with Panorpa rufescens. There had been some confusion because Hagen had compared specimens in his collection with the types and had subsequently deposited his collection in the Museum of Comparative Zoology, Harvard University, where they were studied by Hine, Carpenter, and others. Specimens in his collection were not the true Panorpa venosa, but another species subsequently described as Panorpa helena Byers (1962). In 1993 Byers resurrected the species name for specimens collected at Sapelo Island, 40 miles (64 km) south of Savannah, Georgia. There are four species in the rufescens species group in Georgia. Byers based his decision on the probability that early 19th Century specimens were collected in the vicinity of Savannah, then the administrative and cultural center of Georgia.
