I collected 3 males and 3 females of this species on 29APR2012 (including this one) by sweeping long grass with a net near Cienega Trl. 148, 7400 ft, Sandia Crest 7.5’ quadrangle
in the Sandia Mountains
, Bernalillo Co, NM. I posted a female here:
The subject male keys to Collops histrio
in Fall 1912(1)
and matches the images at the Harvard MCZ database(2)
. A critical key feature is "Basal joint of antenna in the male sinuately excavate or impressed on its posterior face". This is best seen in the anterior
and posterior head
views (compare MCZ ventral view). Other than that, the key is pretty straight-forward, keying to color patterns and (ventral view
) wing development.
Reds faded to orange during chemical treatment. The abdomen in life is very soft and would have shrivelled significantly otherwise, as may be seen in the ventral view of an untreated specimen
in the same genus. To prevent this, I soaked the specimen for a few days each in 95% ethanol, acetone, fresh acetone, HMDS(3)
, then fresh HMDS. The HMDS was then left to evaporate slowly in a covered (but unsealed) glass petri dish. I've subsequently found that the final HMDS soak only results in a small incremental improvement. Acetone alone does a pretty good job
