Found sitting very still in the middle of an unused dirt road, along a sandy open stretch within habitat of alkali scrub and scalds in the Alvord Desert.

This is clearly a male, from the bulky, club-shaped terminalia. Apiocera aren't typically easy to identify to species, especially without opening up the terminalia. But, luckily here, according to Cazier(1) there are only two species occuring in Oregon: A. barri and A. haruspex ssp. martinorum. An image of Cazier's holotype of A. barri can be seen here. An image of Osten Sacken's type of A. haruspex from Yosemite is here. From the discussion and map in Cazier(1), the MCZ image shows the western Sierran subspecies A. h. haruspex (which, of course, also makes sense as it's the type subspecies...the other 3 geographic subspecies were erected by Cazier in 1982, long after Osten Sacken's naming of the species as a single taxon). Cazier mentions that A. haruspex is a variable complex, which is why he created the 4 subspecies...so the MCZ type should not be expected to match perfectly with A. h. martinorum. Indeed, the MCZ image looks different in some respects from "Figure 101" for subspecies martinorum in Cazier(1), and my images match well with Cazier's figure.

From the distribution maps in Cazier(1) for A. barri (pg. 333) and A. h. martinorum (pg. 356), the location of the individual here agrees better with A. h. martinorum. Moreover, a careful reading of the detailed descriptions Cazier gives for the abdominal dorsal patterns for male A. barri (pg. 330) and A. h. martinorum (pg. 358) indicates that this is A. h. martinorum. In particular, for A. h. martinorum Cazier states (green emphasis mine):

"abdominal segment two primarily white pilose dorsally, dark markings on segments two through four narrowly or broadly interrupted dorsolaterally by longitudinal white or gray pruinose vittae (fig. 101), rarely not interrupted, segments five and six with prominent middorsal longitudinal dark line, apical margin of segment three usually entirely or partially black"

Whereas for A. barri Cazier states:

"segment two tricolored, basal third brown pruinose with median posterior extension bordered posteriorly by narrow black transverse vitta, posterior third white pruinose, not completely interrupted medially by black vitta"

The characters described above for A. barri are clearly visible in the image of Cazier's type and do not agree with the individual in this post...whereas the characters described for A. h. martinorum appear to be a very good match.
