KEY TO MALES OF CERATOPSALLUS

1. Phallotheca with two spines, one on ventral surface, the other usually on the anterodorsal surface (figs. 18, 21, 23).. 2

– Phallotheca with a single spine located on ventral surface (e.g., figs. 14, 16)..... 4

2. Posterior process of left paramere very long, smoothly curving in lateral view (figs. 18, 21); left paramere in lateral view extending well beyond right-hand prong of anterior process of paramere (figs. 18, 21); antennal segment 2 in males tapered, diameter less than that of antennal segment 1 over much of length............ 3

– Posterior process of left paramere relatively short, nearly straight in lateral view (fig. 23); body of left paramere in lateral view barely extending beyond right-hand prong of anterior process of paramere; antennal segment 2 in males cylindrical, of about same diameter as antennal segment 1; southern Arizona; Vauquelinia sp. .............. vauqueliniae , n.sp.

3. Spine arising from anteroventral surface of phallotheca spatulate, greatly broadened and flattened on apical third (fig. 18); spots on hemelytra small, more or less uniformly distributed (fig. 2); southern Sierra Nevada, California; Arctostaphylos spp. ................. plautus , n.sp.

– Process arising from anteroventral surface of phallotheca slender, not flattened and broad on apical third (fig. 21); spots on hemelytra clumped, forming a somewhat blotchy appearance (fig. 2); southern Sierra Nevada, California; Arctostaphylos spp. ............... schwartzi , n.sp.

4. Eyes large, head broad (fig. 2); antennal segment 2 cylindrical, diameter about equal to that of segment 1; spotting on dorsum distinctly orange on a pale or weakly pink background.......... 5

– Eyes not so large and head not so broad (fig. 2); antennal segment 2 tapered, diameter less than that of segment 1 over much of length; spotting on dorsum usually green or brown on a weekly greenish dorsum, much less frequently orange on a pale background....... 6

5. Antennal segment 2 very long, ranging from 1.4 to 1.7 times width of head (table 1); ventral spine on phallotheca slender, not flattened (fig. 15); apical processes on right paramere of unequal length, left process much longer than right (fig. 15); vesica very long and slender, forming a complete coil (fig. 15); southern California; Platanus sp. ............................ croceus (Van Duzee)

– Antennal segment 2 shorter, approximately 1.3 times width of head table 1); ventral spine on phallotheca flattened, broad in lateral view (fig. 16); apical processes on right paramere of equal length (fig. 16); vesica J-shaped, not forming a complete coil (fig. 16); southern Oregon to central California; Quercus spp. ......................... pantherinus (Van Duzee)

6. Posterior process of left paramere long and nearly straight in lateral view, extending over most of length beyond the left-hand prong of the anterior process of the left paramere (fig. 22); vesica long and slender, forming a complete coil (fig. 22); southern Oregon to central California; Arctostaphylos spp. .......... septentrionalis , n.sp.

– Posterior process of left paramere much shorter, in lateral view extending only a short distance past left-hand prong of the anterior process of the left paramere (figs. 14, 17, 19, 20); vesica not so long and slender, usually J-shaped.......... 7

7. Left-hand apical process of right paramere much longer than right (figs. 14, 17).. 8

– Left-hand apical process of right paramere only slightly longer than right (figs. 19, 20).......................... 9

8. Right-hand prong of anterior process of left paramere directed away from body of paramere; phallotheca in lateral view with a triangular projection on apicodorsal margin (fig. 17); southern Oregon to western Arizona; Ceanothus spp. , Cercocarpus spp. , etc................ pintoi , n.sp.

– Right-hand prong of anterior process of left paramere nearly erect; phallotheca in lateral view with a ridgelike formation on apicodorsal margin (fig. 14); northern Ca- lifornia, Oregon; Quercus spp ............................ aquilonius , n.sp.

9. Phallotheca with apex blunt and squared off, apicodorsal margin ornamented with a short keel (fig. 20); right-hand prong of anterior process of left paramere sinuously curving (fig. 20); southern Nevada; Ribes sp. ................. ribesi (Knight)

– Phallotheca with apex more or less acuminate, apicodorsal margin with a triangular process in lateral view (fig. 19); right-hand prong of anterior process of left paramere smoothly curving (fig. 19); southern Arizona, southern California; Arctostaphylos sp. , Quercus sp. ....... quercicola , n.sp.
