Female from Colorado River Dunes - Rhaphiomidas parkeri - Female
La Paz County, Arizona, USA
April 1, 2017
View from the rear...the diagnostic character of "hairs on 4th tergite retrorse, pointing anteriorly"...can be seen clearly in the full-resolution version of this image.

(I think the phrase "hairs appressed, pointing anteriorly" would be better...as the word retrorse seems to imply the hairs are "bent back"...i.e. facing posteriorly rather than anteriorly...as stated and intended in couplet 11) of the key to females in Cazier(1).)(1985).
