Truncaudum bullatum Smith, Beaver & Cognato 2020 (in Smith et al. 2020b): 321.
1.9 mm long (n = 1); 2.71 times as long as wide. This species is distinguished by the declivity abruptly truncate, surrounded by a complete costa and margined with a row of variably tubercles; declivital interstriae 1 tumescent; and small size.
This species is strikingly similar to many small Cyclorhipidion species and can be distinguished by the type 2 antennal club (Cyclorhipidion has types 3, 4, 5).
Given the small size of the species, it most closely resembles species in the following genera: Amasa, Arixyleborus, Cyclorhipidion, Pseudowebbia, and Webbia.
