Panorpa choctaw Byers, 1993
Diagnosis: This species is a member of the virginica group that has wings with three complete bands and no humeral spots along the basal margin; males with a horn on the 6th abdominal tergite; male hypovalves that are very thin and extend to the base of the dististyles; ventral parameres that are unbranched, straight, and apically barbed; darkened medial core of the aedeagus; basal lobes of the dististyles with large projections; and male 9th tergite with rounded apico-medial indentation and relatively wide apical lobes (only about twice as long and broad). Panorpa choctaw can be separated from other members of the group by the acute, medial expansion of the ventral margin of the basal lobe of the dististyle; and the ventral parameres extending almost to the tip of the dististyles (further if the dististyles are angled).
Distribution – Geographical: This species is found in the southeastern U.S.A. from Georgia westward to Arkansas and Oklahoma.
Distribution – Temporal: 5 September until 2 October.
Ecology: “Adults of this species occur on shaded low vegetation, primarily at the edges of woods. At the type locality, they were on the regionally typical ecotone vegetation of brambles, greenbriar, honeysuckle, and poison ivy, at the edge of woodes of red oak, white oak, sweet gum, some pine, etc., with a sparse understory of dogwood, sassafras, and other species” (Byers, 1993).
Biology: Nothing is known of immature stages or life cycle.
Notes: The original illustration of this species shows a male dististyle with two elongate expansions of the basal lobe. The male from Alabama illustrated here lacks the dorsal lobe.
