1 Eye located near middle of head by a distance from collar equal to or longer than width of eye........................ 2

- Eyes touching or close to anterior margin of pronotum by distance less than dorsal width of eye....................... 3

2 Postocular region with a neck; pronotum usually with two dark spots near humeral angles (Figs. 1, 5, 9); dorsal surface with punctures on pronotum; vestiture of body and antennal segment I with short pilosity.......................... Collaria

- Postocular region without a neck; pronotum without dark spots near humeral angles; dorsal surface with deep punctures throughout; vestiture of body and antennal segment I with long and erect pilosity (Fig. 17)............... Neotropicomiris

3 Antennal segment I with micro setae shorter than half width of segment; vertex with red lines on each side of inner margins of eyes, pronotum smooth or slightly roughened; scutellum smooth with slight transverse striations (Fig. 13)..... Cynodonmiris

- Antennal segment I without micro setae; vertex without redlines on each side of inner margins of eyes, pronotum and scutellum with deep punctures (Figs. 21, 25, 29).......................................................... Stenodema
