Morphology | Morphometrics
soft rays: 14 - 16;
Vertebrae: 39 - 42. Anal fin of this species is similar to D. robertsi, but differs from it by the combination of melanophores anterior to anal fin in females forming a broad V with a wide base, extending onto lateral surface, directly adjacent to genital papilla and extending anteriorly past level of anus; also the females have an elongate, pigmented genital papilla (Ref. 44897).
