Key to Tyrannidectes species

(Males and females)

1. In females, setae ps2, ps3 represented by suckers, setae h2 with filiform apices ( fissuratus group)..................... 2

- In females, setae ps2, ps3 filiform, setae h2 without filiform apices ( reticulatus group).............................. 5

2. In both sexes, prodorsal shield with a pair of large and deep incisions on posterior margin, setae si situated much posterior to level of setae se ............................................................... T. crassus ( Trouessart, 1885)

- In both sexes, posterior margin of prodorsal shield variable in shape (straight, concave, or slightly sinuous) but without deep incisions; setae si and se situated at same transverse level..................................................... 3

3. In both sexes, hysteronotal shield and posterior half of prodorsal shield with deep and wide median groove.................................................................................. T. fissuratus ( Hernandes and Valim, 2005)

- In both sexes, prodorsal and hysteronotal shields without median groove......................................... 4

4. In both sexes, lateral margins of prodorsal shield without incisions extending to scapular setae, entire surface of prodorsal and hysteronotal shields with numerous circular lacunae. In males, rudimentary sclerites rEpIIa and epimerites IVa present. In females, lobar shield entire, with well developed supranal concavity...... T. amaurochalinus ( Hernandes and Valim, 2006)

- In both sexes, lateral margins of prodorsal shield with incisions extending to setae se (in males) or encircling their bases (in females), and prodorsal shield without lacunae, hysteronotal shield with lacunae in posterior half only. In males, sclerites rEpIIa and epimerites IVa absent. In female, lobar shield split along midline into two pieces, supranal concavity indistinct...................................................................................... T. falcklandicus sp. n.

5. In both sexes, setae c1 situated on striated tegument between prodorsal and hysteronotal shields............................................................................................. T. banksi ( Valim and Hernandes, 2008)

- In both sexes, setae c1 situated on hysteronotal shield........................................................ 6

6. In both sexes, majority of hysteronotal shield with reticulate pattern....................... T. reticulatus ( Černý, 1974)

- In both sexes, hysteronotal shield with another pattern (circular lacunae, transverse striae) or without any pattern.......... 7

7. In both sexes, prodorsal and hysteronotal shields with numerous circular lacunae. In males, aedeagus extending at least to midlevel of anal suckers, setae h3 longer than half-distance between their bases. In females, anterior part of lobar shield with numerous circular lacunae, bases of setae ps2 close to bases of corresponding setae ps3 and both pairs of these setae situated approximately at midlevel of anal opening ( Figs. 22 A, B)....................................... T. cinclodes sp. n.

- In both sexes, prodorsal and hysteronotal shields without circular lacunae. In males, aedeagus scarcely extending to anterior margin of anal suckers, setae h3 not longer than half-distance between their bases. In females, anterior part of lobar shield without lacunae, setae ps2 situated far postero-lateral to corresponding setae ps3, only setae ps3 at level of anal opening … 8

8. In both sexes, setae f2 present, rudimentary humeral shields anterior to bases of setae cp present, hysteronotal shield with deeply concave anterior margin extending to level of setae cp. In males, setae h3 narrowly lanceolate. In females, lateral areas of anterior hysteronotal shield with pattern of oblique and sparse striae, lobar shield almost completely separated along median line into two pieces, supranal concavity not expressed...................................... T. berlai Mironov, 2008

- In both sexes, setae f2 absent, humeral shields absent, anterior margin of hysteronotal shield straight or slightly concave ( Figs. 16 A, B, 17A). In males, setae h3 spiculiform. In females, hysteronotal shield without pattern, lobar shield entire, and supranal concavity present, circular in shape ( Fig. 17 A)................................................ T. anairetes sp. n.
