Rhadinella Smith, 1941

TYPE SPECIES: Rhadinella schistosa Smith (1941) , by original designation and monotypy .

DEFINITION AND DIAGNOSIS: See group definition in Myers (1974: 119). Separated from Rhadinaea and most other dipsadines by the straight-line arrangement of several enlarged posterior maxillary teeth (ultimate fang not offset).
