Representative material deposited in MALUZ, MIZA, MFPC and NMW.

Diagnosis. Total length: 1.8–2.3 mm. This species is distinguish by the following character combination: interstria X usually with a single row of elytral ground punctures ( Fig. 6View FIGURES 6 – 9), a fine, linear metasternal carina, and with both teeth of the process of the mesoventrite subequal in length, more or less coplanar. This species may be easily confused with smaller specimens of D. rudis  , which has more punctures in interstria X ( Fig. 8View FIGURES 6 – 9) and broadly quadrate parameres (tapered in D. altus  ). It is also easily mistaken for D. terraenovae  , but can be distinguish by having the two mesosternal teeth of different heights.

Distribution. Widespread from the Atlantic and Gulf Coasts, through Central America, South America, and the Caribbean: Argentina, Bolivia, Brazil, Paraguay, Costa Rica (new record), “West Indies”, U.S.A. (Florida, Illinois, Louisiana, Missouri, Mississippi, New Jersey, Texas, Virginia).

Remarks. The widespread species is the only member of the genus to occur outside the Neotropics. While recorded as far north as New Jersey in the United States, it is generally uncommon north of the Gulf Coast. It has been collected at lights and in stagnant, often vegetation-choked marshes and swamps.
