Key to species of the subgenus Quiva

(Adapted from Cadena-Castañeda & Gorochov, 2013)

1. Male cerci with almost truncate distal part of outer branch having much thinner apical spine; inner branch of these cerci very short, much shorter than outer branch (fig. 21)............................................... Diaphana group (2)

- Male cerci with more or less gradually narrowing distal part of outer branch (apical part of this branch insignificantly narrower than its remaining part); inner branch of these cerci diverse in length (fig. 24, 27)..................... Abacata group (4)

2. Short postero-dorsal projection of last abdominal tergite of male not very wide and with straight or slightly concave posteromedian edge; outer branch of male cerci with medial curvature of its distal part located rather far from base of inner branch, and with very thin apical spine............................................................... Quiva pulchella

- Short postero-dorsal projection of last abdominal tergite of male very wide and with approximately straight postero-median edge (fig. 20); outer branch of male cerci with medial curvature or not, and with moderately thin apical spine............. 3

3. Reddish-brown body spots (figs. 10, 11). Prozone and metazone spots of pronotal disc little prominent (fig. 12). Cerci in dorsal view with medial curvature of its distal part located not far from base of inner branch.................... Quiva diaphana

- Black or bluish black body spots (fig. 1). Prozone and metazone spots of pronotal disc prominent (fig. 6). Cerci in dorsal view without medial curvature, only slightly curving at apex (fig. 20)............................. Quiva buhrnheimi n. sp.

4. Outer branch of male cerci with rounded medial convexity at base of dorsally darkened part of this branch and with the rest of this darkened part wide; inner branch of male cerci short, not curved backwards (figs. 23, 26)......................... 5

- Outer branch of male cerci with acute medial denticle at base of dorsally darkened part of this branch and with the rest of this part thin; inner branch of male cerci much longer and curved backwards................................ Quiva sharovi

5. Cerci 1.3 times longer than subgenital plate. Apex of subgenital plate is not expanded sideways (fig. 24, 25)... Quiva abacata

- Cerci two times longer than subgenital plate. Apex of subgenital plated moderately expanded sideways (figs. 27–28).......................................................................................... Quiva gutjahrae n. sp.
