Abstract

The Neotropical species of the genus Diochus are reviewed. Two species are synonymised: D. flavicans Sharp, 1876 = D. vicinus Sharp, 1876 and D. vilis Sharp, 1885 = D. schaumii Kraatz, 1860. Six species groups are differentiated containing the following species: D. longicornis-group with the species D. adisi spec. nov., D. ashei spec. nov., D. guianensis spec. nov., D. longicornis Sharp, 1876, D. tarsalis Sharp, 1876, and D. unicolor spec. nov.; D. inornatusgroup with the species D. antennalis Cameron, 1922, D. amazonensis spec. nov., D. hanagarthi spec. nov., D. hermani spec. nov., D. hibbsi spec. nov., D. inornatus Sharp, 1885, D. newtoni spec. nov., D. novus spec. nov., D. plaumanni spec. nov., D. schuelkei spec. nov., D. tricolor spec. nov., and D. vicinus Sharp, 1876; D. maculicollis-group with the species: D. brooksi spec. nov., D. ecuadoriensis spec. nov., D. maculicollis Fauvel, 1891, D. mexicanus spec. nov., D. panamaensis spec. nov., D. peruvianus spec. nov., and D. pumilio Bernhauer, 1929; D. schaumii-group with the species D. angustiformis spec. nov., D. argentinus spec. nov., D. brunneus spec. nov., D. curtipennis spec. nov., and D. schaumii Kraatz, 1860; D. verhaaghi-group with the two species D. verhaaghi spec. nov. and D. santacatarinae spec. nov.; D. nanus-group with the species D. apicipennis Cameron, 1922, D. nanus Erichson, 1839, D. parvulus Kraatz, 1860, and D. perplexus Cameron, 1922. D. formicetorum Bernhauer, 1927 is with unclear position among the named groups. A key to the species groups and to species is provided. The relation among groups, the ecology, and the geographic distribution is discussed.
