A "new" species for the guide! David McCoy keyed it out to Neortholomus nevadensis (Baker,1906) using Hamilton, Steven W. 1983. Neortholomus, a new genus of Orsillini (Hemiptera-Heteroptera: Lygaeidae: Orsillinae). University of Kansas Science Bulletin 52(7):197-234 (1983) http://biostor.org/reference/40450

Neortholomus scolopax, after all...
Moved from Neortholomus nevadensis.

(Same comment here as for the female...) I can see how David may have gotten the impression that the ocelli are on the imaginary line across the posterior margins of the eyes (part of the couplet in Hamilton's key that differentiates scolopax from nevadensis), because in the dorsal photos the vertex of the head is tilted down and forward rather than level (which is the head’s natural position when the insect’s body overall is level). Because the ocelli are higher on the head than the rear margin of the eyes, tilting the head forward has the effect of moving the ocelli forward, relative to the rear margin of the eyes. The key specifies that the head would need to be “viewed with vertex level” for this assessment (which would mean tipping the front of the insect’s body upward about 20 degrees, and would also move the ocelli back relative to the rear margin of the eyes). This is not a problem of the photo, but in the use of it.

Anyway, the angle of the rear margin of the head behind the eyes matches that of N. scolopax (obliquely angled), and not at all that of N. nevadensis (straight and perpendicular to the long axis of the head), which is also in that couplet of the key and should settle any lingering doubt from the assessment of the position of the ocelli.
