Panorpa hispida  Byers, 1993


Diagnosis:  This species is part of the rufescens species group that has one marginal spot along the base of the forewing costal margin, and shading along many of the distal crossveins; males with narrow hypovalves;  and dististyles with a basal lobe that is apically truncate and bears a row of spines along the dorsal margin.  The ventral parameres have lateral props to the inner wall of the basistyles.  Panorpa hispida belongs to the subgroup with heavy, dark spines at the apex of the male basistyles.  Panorpa hispida also has narrow hypovalves that are bowed laterally at mid-length and scattered, long setae along the medial margin.  The male ventral parameres extend slightly beyond the base of the dististyles, are concavely bowed on their apical 2/3; and have a long row of thick spines along the entire medial surface.  The female genital plate has broad lateral arms and an elongated, triangular, apico-medial notch.


Distribution – Geographical:  This species is only known from central and western South Carolina, and southeastern Georgia.


Distribution – Temporal:  There are two generations per year.  Known adult emergences are from 14 until 19 May and 26 September until 30 October.


Ecology:  Nothing is known of habitat preferences for this species.


Biology:  Nothing is known of immature stages or life history.




Among the members of the rufescens species group with long, dark spines at the apex of the basistyles, this species stands out because of the long setae along the mesal margin of the hypovalves.  The most closely allied species is probably P. scopulifera, which also has these long setae.  They can be separated by the longer ventral parameres of males and triangular apical notch of the genital plate in females of P. hispida.  However, additional collecting in intermediate areas may suggest that these are regional variants of the same species.


The name “hispida” comes from the Latin word “bristly” and refers to the long, dark bristles at the apex of the male basistyles; the long, dark setae along the mesal margin of the ventral parameres; and the long setae at the margins of the female subgenital plate (Byers, 1993).
