? Ocnerodrilus ? sp.

Material. USNM 1180247 , subadults, banks and riparian area of small stream inland near large antenna, Gamba Complex , Gabon, 2.84873S, 10.23569E, 22 m asl., 16 May 2008; S. James, G. Divina, G. Moussavou and L. Tchignoumba, colls .

Description. Unpigmented, slender; spermathecal pores paired in 8/9 at CD level; paired prostatic pores XVII, XVIII. Septa 5/6–8/9 muscular, other septa membranous; gizzard lacking, intestinal origin XII, typhlosole lacking. Sub-esophageal glands paired (or partly fused, but with paired ducts?) in IX, ental portion without lumen, a solid body of parallel small tubules; ectal portion with small central lumen. Last hearts in XI. Tubular prostates paired in XVII, XVIII, coiled under intestine. Seminal vesicles in IX, XII. Spermathecae tubular, adiverticulate in IX.

Remarks. By having spermathecae, these individuals fall outside the boundaries of Ocnerodrilus Eisen and into Ilyogenia Beddard but some authors (e.g. Blakemore 2006) consider the latter to be a thecate morph of O. occidentalis Eisen, 1878 .
