Diagnosis

This species is similar in general appearance to D. chevron except that the median stripe of the pronotum has the same hue as the Vshaped banding of the vertex and pronotum whereas in D. chevron, the median stripe is paler than the other marking. In addition, D. chevron has two transverse lines across the front of the head with indications of a third at the front margin of the red band whereas D. sagittatus has four dark bands extending from eye to eye. The lateral processes of the aedeagus are also larger and more obvious in D. sagittatus than in D. chevron. In male genitalia, it is most similar to D. linnavuorii which lacks the distinctive red markings of this species (Fletcher 2017).
