Previoulsy placed under genera Pseudaxinella and Ectyoplasia (as Ectyoplasia ferox explicata). Thick bright orange or red encrustations with volcano-like oscules having a wide rim and often partly or totally closed by a diafragm; surface often spiny or having a honeycombed pattern of ridges. It was previously synonymized with Dragmacidon reticulatum (=also locally known as Pseudaxinella lunaecharta). However, this is a clearly distinct although similarly-looking species, coexisting with D. reticulatum in some areas (Stirrups Cays, Bahamas, Santa Marta, Colombia), with distinct spicules. D. explicatum has a more elaborated surface and is tougher, while D. reticulatum has a smoother surface is softer and often grows erect. In coexisting specimens, D. explicatum has some of the styles spicules as long as the oxea spicules, while D. reticulatum has oxea larger than styles. |

Previously known as Pseudaxinella lunaecharta Ridley and Dendy, 1886, a name from the E. Atlantic. Small masses to erect clubs or thick lamellae, brigh orange or red; surface usually smooth, with scattered oscules, often flush to the surface, and aligned on the upper ridges. Dragmacidon explicatum was placed in synonymy with D. reticulatum but they are clearly distinct species, in overall shape and spicule characteristics. They coexist in some areas (Stirrups Cays, Bahamas, Santa Marta, Colombia). D. reticulatum has a smoother surface and often grows erect, while D. explicatum has a more elaborated surface and is predominantly thickly encrusting and slightly softer. In coexisting specimens, typically, D. reticulatum has oxea spicules larger than the style spicules, while D. explicatum has some of the styles as long as the oxea. |
