II. Tricyphona subaptera ( Alexander 1917) .

USA: California: Ansel Adams Wilderness, Mono Co. , East Donohue Pass, 37.7615°N, 119.2394°W (WGS84). 2 ♂, 17 July 2016, 13:00–14:00 hrs., S.D. Schoville and B.A. Pieper. Specimen code SDS16-335 ; Genbank accession code KY114056 . Specimens deposited in the California Academy of Sciences ( CASENT 8125473 and CASENT 81254754 , respectively) .

The collection of T. subaptera occurred at mid-day, in a grassy alpine meadow near a small creek (the air temperature was about 22–25°C). Talus habitat otherwise dominates the locality. The specimens, one of which is shown in Fig. 2 , were found next to one another, walking in the grass, about two meters from the creek edge.

Tricyphona subaptera displays brachyptery in both sexes. Although this species has previously been collected from Yosemite National Park and nearby areas, the most recent of the earlier collections was made in 1957.
