摘要

The tropical Central and South American genus Parosus Sharp, 1887 is reviewed. Adults are most frequently found in forest litter or collected from narrow spaces between sappy plant parts. The three earlier named species are redescribed with the most distinctive of the still unnamed taxa added to this account. Lectotypes are designated for P. hilaris Sharp and P. skalitzkyi Bernhauer. Seventeen new taxa are described in this paper: P. bicoloratus sp. nov. (Ecuador: Pichincha), P. brasilianus sp. nov. (Brazil: S?o Paulo), P. campbelli sp. nov. (Ecuador: Napo), P. colombiensis sp. nov. (Colombia: Magdalena,Ecuador: Napo), P. gigantulus sp. nov. (Colombia: Magdalena),P. hermani sp. nov. (Ecuador: Cotopaxi, Pichincha), P. longi- cornis sp. nov. (Peru: Junin), P. longipennis sp. nov. (Bolivia: Cochabamba, Peru: Cuzco), P. major sp. nov. (Peru: Cuzco, Bolivia: La Paz, Cochabamba, Santa Cruz), P. minutus sp. nov. (Panama: Panamá), P. newtoni sp. nov. (Panama: Bocas del Toro, Panamá), P. portobelo sp. nov. (Costa Rica: Colon, Coclé, Puntarenas, Panama: Heredia), P. rossii sp. nov. (Costa Rica: Cotopaxi), P. simplex sp. nov. (Peru: Cuzco), P. taliaferroae sp. nov. （Panama: Coclé， Bocas del Toro， Chiriquí）， P. thayerae sp. nov. (Peru： Huánuco), P. unicoloratus sp. nov. (Brazil: S?o Paulo). The diagnostic characters are illustrated for all species and a key is presented for well- developed specimens.
