Deland, C., Cameron, C. B., Rao, K. P., Ritter, W. E. & Bullock, T. H., 2010, A taxonomic revision of the family Harrimaniidae (Hemichordata: Enteropneusta) with descriptions of seven species from the Eastern Pacific, Zootaxa 2408 (1), pp. 1-30 : 7

Genus Ritteria n. gen.

Type species. Ritteria ambigua n. sp.

Diagnosis. Proboscis short, the longitudinal muscles dispersed diffusely, not concentrically or radially. A single, left proboscis pore. Proboscis neck severely reduced, the stomochord lumen broken into lacunae. Collar with neither dorsal nor ventral septum and no peribuccal cavities. Dorsal gonads present, the lateral gonads forming two pairs of genital ridges with branchial pores recessed in the groove between them.

Remarks. The genus is monotypic for R. ambigua n. sp., which is fully described in the section on new species descriptions, below. The genus is named in honor of the late Professor W. E. Ritter, without whose interest and initiative our knowledge of the Enteropneusta would be very much poorer. He never saw the material on which this name is based.
