Etymology. From the Latin adjective angustus meaning narrow and referring to the overall appearance.

Diagnosis. Only likely to be confused with D. inretitus from which it may be distinguished by the pronotum which is widest medially, hind margin of head without a semi circular depression, the presence of metaventral lines, by the longer and denser elytral pubescence, and the microtrichae on the first visible abdominal ventrite..
