Key to Subfamilies of Leiodidae View in CoL of Latin America (modified from Newton, 1998)

1a Head with distinct occipital carina or elevated crest; widespread........................................ Cholevinae View in CoL

1b Head without occipital carina or crest..................................................................... 2

2a Antennal segment 8 as large as segments 9 – 10 and bearing similar periarticular gutter and internal vesicles; cervical sclerites absent; intersegmental membranes between abdominal ventrites long, with brick-wall pattern of minute sclerites; female with 4 visible abdominal ventrites; Chile, Argentina, Mexico, Guatemala, Honduras............................ Coloninae

2b Antennal segment 8 smaller than segments 9 – 10, without periarticular gutter or internal vesicles, or antenna 10-segmented; cervical sclerites present; abdominal intersegmental membranes short and without minute sclerites; females with 5 or 6 visible abdominal ventrites................................................................................... 3

3a Pronotum semicircular with evenly rounded anterior edge, head in repose completely concealed from above; hind coxae separated by nearly a third of their width by elevated metaventral process; tarsi 3-3-3 segmented; Chile.......... Catopocerinae View in CoL

3b Pronotum with straight or emarginate anterior edge, head not concealed from above; hind coxae not separated; tarsi various, 3 – 5 segmented or heteromerous.......................................................................... 4

4a Antennal insertions concealed in dorsal view; head relatively flattened and broad, usually about half or more as wide as pronotum; dorsum usually apparently glabrous (but sometimes with numerous very short hairs visible at high magnification); mesoventral-mesepisternal suture (if present) strongly curved; widespread................................. Leiodinae View in CoL

4b Antennal insertions visible in dorsal view; head relatively convex and narrow, often less than half as wide as pronotum; dorsum usually clothed with long setae, rarely apparently glabrous; mesoventral-mesepisternal suture (if present) more or less straight; southern South America........................................................................
