(Brazil), S. cruciphallus sp. n. (Panama), S. delta sp. n.(Brazil, Paraguay); S. emissarium sp. n. (Costa Rica), S. epulum sp. n. (Brazil), S. garciai sp. n. (Costa Rica, Panama, Venezuela); S. inconnivum sp. n. (Costa Rica, Panama), and S. lebbinorum sp. n. (French Guiana, Peru, Brazil). Sacosternum megalopus Hansen, 1989 is newly recorded from Costa Rica. Two species, referred to as Sacosternum sp. A (Peru) and S. sp. B (Costa Rica) are left undescribed pending on the collecting of males. Additional unidentified specimens are recorded from Mexico (Veracruz State), Guatemala,Costa Rica, Panama, and Venezuela. A key to known species of the genus is provided, important characters are illustrated.
