Creators
Description
Description: Length 30–40 mm. Prostomium epilobous. Male pores in 17, with male porophores extending to the ventral part of the clitellum, connected by seminal grooves with prostatic pores. Clitellum saddle-shaped on 13–19, 20, marked ventrally by prominent, paired male porophores on 17, connected by a ventral transverse groove between prostatic pores in 17 and 19. Nephropores near b setae. Prostates one pair, much elongated, can reach segment 24. Septa 5/6–11/12 thickened somewhat thickened. Gizzard absent. Holandric. Calciferous glands paired, large, in segment 9. Spermathecae absent.
Notes: Widely distributed in tropical and temperate areas, as noted by Righi (1984) and Zicsi (1996, 1997). In RSA reported by Černosvitov (1940), Ljungström (1972), and Zicsi (1998). A thecate form of this species, Ocnerodrilus africanus Beddard, 1878, assigned by Michaelsen (1913) and Zicsi (1998) to the genus Ilyogenia, may not occur in this country, as discussed by Plisko (2010), and is not included in this paper.
