KEY TO MALES OF PHYMATOPSALLUS

Medial vesical spine very long, approximately one-third the length of vesica (figs. 33, 34)................... 2 Medial vesical spine much shorter, at most one-fourth the length of vesica (figs. 30– 32) .......................... 3

2. Medial vesical spine inserted relatively close to secondary gonopore, distance equal to less that half the length of spine; vesica not twisted on apical two-fifths, portion apical of secondary gonopore straight in lateral view (fig. 34)...................... tuberculatus (Van Duzee)

– Medial vesical spine inserted farther from secondary gonopore, distance equal to more than half the length of spine; vesica twisted on apical two-fifths, portion apical of secondary gonopore weakly curving in lateral view (fig. 33).... rinconae Knight

3. Small species, total length 2.17 or les table 1); eyes small (fig. 3).............................. acaciae Knight

– Larger species, total length always greater than 2.36 (table 1); eyes larger (fig. 3)... 4

4. Medial vesical spine very short, removed from secondary gonopore by distance about equal to length of spine (fig. 31)................... dubiosus (Van Duzee)

– Medial vesical spine somewhat longer, removed from secondary gonopore by distance slightly less than length of spine (fig. 32)........... patagoniae Knight
