Panorpa braueri Carpenter, 1931
Diagnosis: This is one of five species of North American Panorpa that form part of the anomala group. This group can be defined by the following characteristics: Forewings with three bands, the pterostigmal band branched posteriorly, but usually interrupted medially so that the apical branch appears to be an isolated spot, and the basal band also usually interrupted medially; two humeral spots along the basal margin; and most crossveins darkly margined. Anal horn present on the male 6th abdominal tergite. Male hypovalves almost as long as basistyles. Ventral parameres curved, unbranched and joined at base, short – only reaching base of dististyles, bearing a tuft of bristles apically. Inner margin of basistyles with a small tooth at mid-length. Basal lobe of dististyles disc-shaped with slight expansion of dorsal margin and small tuft of bristles along ventral margin. Panorpa braueri can be separated from all other members of this group by the unbranched ventral parameres with single tuft of bristles apically.
Distribution – Geographical: This species is restricted to southern Missouri and northwestern Arkansas (Webb et al, 1975).
Distribution – Temporal: 13 May to 20 August.
Ecology: Byers (1954) reported collecting this species on jewelweed in a shaded swale in southern Missouri.
Biology: Nothing is known of immature stages or life history.
Notes: This species is named for Friedrich Moritz Brauer, a 19th Century Austrian entomologist who did pioneering work on mecopteran biology (http://en.wikipedia.org/wiki/Friedrich_Moritz_Brauer).
