Panorpa capillata  Byers, 1996


Diagnosis: 
This species belongs to the nebulosa group with speckled wings and males without an anal horn on the 6th abdominal tergite.  It also belongs to the subgroup in which males have a cluster of spines at the meso-apical corner of the basistyles, and a series of bristles along the mesal surface of the ventral parameres.  It can be separated from all other species, except P. sigmoides, by the male ventral parameres being sigmoidally shaped with a cluster of thick, small bristles subapically.   Males of P. sigmoides can be separated from P. capillata by the glabrous ventral surface of the ventral parameres and the dark spines along the mesal surface of the hypovalves of P. sigmoides.


Distribution – Geographical: 
This species is known from the Gulf Coast states of the U.S.A. northward to Arkansas and Kentucky.


Distribution – Temporal: 
11 April until 3 June.  There is one isolated pitfall trap record from 6 July – 10 November.


Ecology: 
Byers (1996) indicates that the habitat for this species is a wide variety of broadleaf overstory trees, with an understory of honeysuckle, brambles, poison ivy, and sometimes greenbriar.  Wes Bicha (Byers, 1996) has found this species in deep shade along small streams.


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


Notes: 
This species is very similar to P. sigmoides and might be considered a distinct subspecies.

 

The name capillata refers to the dense small bristles along the apical third of the male ventral parameres.
