Key to male adults of Sierracapnia View in CoL View at ENA

Key. Male adults of Sierracapnia species are separated by differences in (1) tergum 7 knobs, (2) epiproct proportions and curvatures, (3) epiproct membrane (or eversible crest), and (4) dorsolateral horns.

1 Epiproct linear in both dorsal and lateral view; shallow ventral keel ( Figs. 13-15 View Figs ) ............ palomar View in CoL

1’ Epiproct thick in lateral view; deep ventral keel ( Figs. 2 View Fig , 6 View Figs , 10 View Figs , 18 View Figs , 29 View Figs , 36) ....................................... 2

2 Tergum 7 knob narrow (10-15% segment width) ( Figs. 3 View Fig , 8 View Figs , 37 View Figs ) ..............................…....................... 3

2’ Tergum 7 knob wide (30-35% segment width) ( Figs. 9 View Figs , 17 View Figs , 26 View Figs ) ……………................................... 5

3 Dorsolateral horns appressed to main epiproct body, membrane not visible below horns (lateral view); epiproct apex not raised; epiproct ventral keel less prominent ( Fig. 6 View Figs ) .......... hornigi View in CoL

3’ Dorsolateral horns arch above main epiproct body and expose membrane laterally; epiproct apex raised; epiproct ventral keel prominent ( Figs. 2 View Fig , 36 View Figs ) …………………………………......... 4

4 Tergum 7 knob not notched and medium high (20-25% of tergum 7 height) ( Figs. 2, 3 View Fig ); epiproct base with ventrolateral flange ( Fig. 1 View Fig ); tips of dorsolateral horns extend forward to 70-78% of epiproct length ( Fig. 2 View Fig ) ............................... barberi View in CoL

4’ Tergum 7 knob notched and tall (30-35% of tergum 7 height) ( Figs. 34, 37 View Figs ); epiproct base lacks ventrolateral flange ( Fig. 35 View Figs ); tips of dorsolateral horns extend forward to 85-88% of epiproct length ( Fig. 34 View Figs ) ........................... yosemite View in CoL

5 Epiproct dorsal membrane light colored; epiproct apex narrow (dorsal view) ( Figs. 9, 10 View Figs ) …………….…….............................................. mono View in CoL

5’ Epiproct dorsal membrane dark gray or black ( Figs. 22 View Table 1 , 24 View Figs ); epiproct apex more broadly rounded ( Fig. 28 View Figs ) ……………….......................... 6

6 Epiproct depth ≤20% length; epiproct reversely curved (lateral view); dorsolateral horns 14-18% epiproct length ( Fig. 18 View Figs ); epiproct width uniform in apical third ( Fig. 17 View Figs ) ………...………………………........…....... shepardi View in CoL

6’ Epiproct depth>20% length; epiproct less reversely curved; dorsolateral horns 24-29% epiproct length ( Fig. 29 View Figs ); epiproct width increases in apical third ( Figs. 26, 28 View Figs ) …………………….............................. washoe View in CoL sp. n.
