Remarks
Kuschelina Bechyné differs from Alagoasa Bechyné by having moniliform antennal segments; smaller eyes (diameter less than 3 times as small as width of frons); head (frons/vertex) rugosely punctured;
male terminal sternite ventrally without depression; epipleura bent/slanted downward, i.e., visible in lateral view; elytral pleura narrow, not grooved or explanate; antero-lateral corners of pronotum only
slightly protruding (not appearing to surround eyes/head; body shape elongate oval (not very rounded). The first placement of North American Oedionychus Berthold or Oedionychis Latreille
(most Alagoasa were placed in one of these generic names previously) into Kuschelina was by Balsbaugh and Hays (1972) [for 14 spp.]. (1)
