Spirotropis genilda is a small sea snail in the family Drilliidae. It has a white shell about 10.5 mm long and 4.6 mm wide, with around six whorls (not counting the lost initial whorl). The shell features a distinct suture and a slightly bulging whorl just in front of it. Along the shoulder there are about fifteen short, very oblique, wave-like ribs with narrow spaces, most visible near the edge. The surface is smooth apart from faint growth lines. The opening is crescent-shaped (lunate), and the anal notch is wide and shallow. The outer lip is sharp, thin, and curved in front of the notch. The body is smooth, the columella short and twisted, and the siphonal canal is very short and slightly curved. There is no operculum on the holotype.

Habitat: Demersal (on the seafloor) in the Gulf of Panama at a depth of about 2300 meters.
