Curated specimen from the Essig Museum - Physoconops townsendi - female

Curated specimen from the Essig Museum - Physoconops townsendi - Female
Portal, Cochise County, Arizona, USA
July 11, 1963
In addition to being curated as Physoconops townsendi, this female keys unambiguously to that species in Camras (1955) and agrees well with Townsend's original description here (under Conops auratus, later found to be a preoccupied name, and changed to P. townsendi).

Among the salient characters are:

1) the complete post-vertical pollinose stripe along the hind-edge of the head (uninterrupted below the vertex). This is a distinctive character shared only by P. excisus (and sometimes P. bulbirostris) among Physoconops species in our area. It is clearly visible in the last two images of this series.

2) The brown spot on the cheeks.

3) The conspicuous pollinose markings on the pleura, coxae, humeri, and elsewhere. Also the abundant yellow dusting on the distal tergites.

4) The very large theca.

5) The 3rd antennal segment more or less equal to the 2nd.

The length of the proboscis, color pattern of the frons and vertex, legs, wing infuscation, and other characters are also all in good agreement with P. townsendi, which is very similar to P. excisus but more rufous (rather than dark brown to black) in overall body color and more western in its distribution (although I believe we may have posts on BugGuide of P. townsendi from Florida and southern Georgia...and this web page from the University of Lund indicates a curated specimen of P. townsendi from Florida).
