A new species of the genus Trimma is described. Trimma volcana is characterized by having large spots on the head and body, moderate to well-developed interorbital and postorbital trenches, scales present on the pectoral and pelvic fin bases but not on the cheecks, opercles, or midline of the nape, a posterior nostril which is adnate to the eye, and a fifth pelvic fin ray that is 80-9% of the fourth and is branched dichotomously twice. Trimma volcana has been found off Tanzania, Mozambique and the Comores Islands.
