This genus is found in the lowlands of South America, and groups three species: Apotetamenus amazonae Brunner von Wattenwyl, 1888 ( type species, Western Amazon and Amazon foothills, between Bolivia and Ecuador ), A. clipeatus Brunner von Wattenwyl, 1888 ( Bolivia , southeastern Brazil and northern Argentina ) and A. gorochovi Cadena-Castañeda & Cortés-Torres, 2013 ( Colombia , Guainia , Amazon region) ( Cadena-Castañeda & Cortés-Torres 2013 , Cigliano et al . 2022 ) ( Map 2 ). It is distinguished from the other Lutosinae /ini, because the pronotum is elongated, and covers the other thoracic segments, and in some specimens even the first abdominal tergites ( Fig. 15A,B ). In addition, the species with known males (except A. gorochovi ), has the last tergite narrow, paraprocts thick, pointed, and sclerotized, and subgenital plate without styli.
