 2. Male with protarsus apparently triungulate with bifid claw (Fig.13a); epistomal suture absent (Fig. 13b); elytra with vivid “cloverleaf” pattern of pale spots (SE Australia)..................................................................................... Cholevomorpha Blackburn, 1891

 3. Labrum as long as wide, antennae slender, habitus slender­legged (Fig.14b), pronotum constricted anteriorly; elytra tapering posteriorly. Mesosternum always distinctly carinate; male protarsus not broadly expanded (New Zealand) (“ Zeagyrtes group”)...... 4   
– Labrum short and transverse; body compact and convex with relatively stout, robust legs and distinct antennal club (Fig. 14a). Mesosternum carinate or not; male protarsus always expanded................................................................................................... 6  
 4. Distinctive elytral color pattern of 3+ transverse chevron­shaped stripes. Epistomal suture present. Parameres bent medially or hooked at apex...................................... 5   
 – Elytra medium­to­dark brown, marked evenly with white spots (on which pubescence is silver) or with indistinct posterior “wash” of pale tan. Epistomal suture absent. Parameres distally curved, but not hooked ........................ Zearagytodes Jeannel, 1936   
 5. Elytra with faint “chevron” stripes; pronotum with dark medial stripe and often with paired dark spots at the lateral margins. Median lobe short and truncate, not tapering along length. Aedeagal parameres distinctly hooked, bearing two small apical setae (Fig. 15). Labrum elongate...................................................... Zeagyrtes Broun, 1917   
 – Elytra with three dark fasciae. Median lobe short and triangular in shape, tapering evenly from base to apex. Parameres slender, bent medially but not hooked, without short apical setae. Labrum transverse .................... Zeagyrtoma Szymczakowsi, 1966   
 6. Elytra with “S”­shaped, tricolor pattern (Fig. 16) and conspicious, long, shaggy, dorsal vestiture; elytral lateral striation indistinct. Body length <1.7 mm (E Australia) .......................................................................................... Agyrtolasia Szymczakowski, 1973   
 – Elytra solid brown, without tricolor pattern; dorsal vestiture short, even, and dense; elytra with conspicuous lateral striation. Body length> 2 mm (Australia, New Zealand, Chile)..................................................................... Agyrtodes Portevin, 1907   
 7. Mesosternal carina acute, conspicuously pointed. Hind tibia curved along length. Large for agyrtodines, body length 3–3.5 mm (Chile).......... New Genus “F” (in prep)   
– Mesosternal carina absent, or low and rounded (if present, then body length less than 2 mm). Hind tibiae not curved; body length typically <3 mm...................................... 8  
 8. Hind wings absent; body length 2 mm or less............................................................ 9   
– Hind wings present; body length almost always> 2 mm.......................................... 11  
 9. Protibia bent medially and expanded apically (Fig.17); smoothly rounded mesosternal carina present (New Zealand)............................. Chelagyrtodes Szymczakowsi, 1973   
– Protibia straight, neither bent nor apically expanded; mesosternal carina absent or extremely low............................................................................................................ 10  
 10. Maxilla with apical palpomere expanded (Fig. 18a); epistomal suture with stem. Eyes reduced. Elytra with faint transverse striae. Tarsal formula 4­4­5 (Tasmania).............................................................................................................. New Genus 1 (in prep.)   
– Maxilla with penultimate palpomere expanded, substantially more so than apical palpomere (Fig. 18b). Epistomal suture without stem. Elongate, non­striate elytra. Tarsal formula 5­5­5 (New Zealand)............................................ New Genus 2. (in prep)  
 11. Male sternite VII with paired hook­like processes (Fig. 19a); large, curved spine on ventral face of mesofemur (Fig. 19b) (S Chile, Argentina)....................................................................................................................................... Dasypelates Portevin, 1907   
– Male sternite VII and mesofemur without hooks or spurs......................................... 12  
 12. Aedeagal parameres expanded and flattened apically, with paddle­like or spoon­like shape (e.g., Fig. 21)................................................................................................... 14   
– Aedeagal parameres slender, without notable apical expansion (Figs. 20a, b) (S Africa)......................................................................................................................... 13  
 13. Parameres with strong median bend; median lobe short, broad, and apically truncate (Fig. 20a). Elytra with transverse striae............................... Dictydiella Jeannel, 1936   
 – Parameres straight or slightly curved; median lobe with “nipple” or gentle hook at apex (Fig. 20b). Elytra without transverse striae................. Afropelates Jeannel, 1964   
 14. Aedeagal parameres broadly expanded, with spoon­like flattened apex bearing at least one row of long setae on interior face (Fig. 21); male mesotarsus with segments 1–2 dilated. Male sternite VI cleft; body length> 3.5 mm (Australia)................................. .............................................................................. Paragyrtodes Szymczakowski, 1966
