Key to Tribes of Leiodinae View in CoL of Latin America (modified from Newton, 1998)

1a Labrum deeply emarginate apically; mandibles with molar lobes usually reduced, smooth, not contiguous; lacinia with dense brush of setae along entire mesal edge, galeal brush relatively much smaller; tarsal formula 5-5-5 or 5-5-4, not sexually dimorphic................................................................................................ 2

1b Labrum shallowly or not at all emarginate apically; mandibles with well-developed, contiguous molar lobes bearing grinding surfaces; lacinia with setal brush concentrated along apical half of mesal edge, galeal brush subequal or larger in size; tarsal formula 5-4-4, or more reduced, or sexually dimorphic (5-5- 4 in male, more reduced in female)....................... 4

2a Tarsal formula 5-5- 4 in both sexes.................................................................. Leiodini View in CoL

2b Tarsal formula 5-5- 5 in both sexes........................................................................ 3

3a Mesocoxae very narrowly separated; first tarsal segment as long as or longer than second segment................ Sogdini View in CoL

3b Mesocoxae separated by about their length; first tarsal segment much shorter than second segment............... Estadiini

4a All tarsi 3-segmented; abdominal ventrite III (first visible) with transverse carina......................... Scotocryptini View in CoL

4b All tarsi of at least 4 segments; abdominal ventrite III without transverse carina.................................... 5

5a Head without antennal grooves below; tarsal formula 5-4- 4 in both sexes; elytron usually transversely striolate; aedeagus with free parameres............................................................................. Pseudoliodini View in CoL
