It is described the anatomy and microanatomy of the phallus complex of Rectartemon depressus (Heynemann, 1868). The complex is composed by a phallus, a diverticle of the phallus and an epiphallus, where the deferens duct is thrown in: the retractor muscle is splitted in two parts, inserted into the region of the epiphallus through a smaller branch, and at the extremity of the diverticle, through a longer and thiner branch. The lumen of the phallus, epiphallus and diverticle have corrugations and thorns. On the phallus the thorns are arranged in a protuberance and disposed alternately in rows, ali with an aculeus form and with a chestnut collor point and a yellow basis.
