Diagnosis Worsaae et al. (2021) "A microscopic annelid lacking appendages and chaetae, having multiple indistinct segments.The prostomium, peristomium, and pygidium are well delineated by ciliary bands and epidermal constrictions. A muscular pharyngeal bulb is absent. Ventrally, three dense longitudinal bands of locomotory cilia extend along the trunk. Internally, the densely ciliated mouth opens ventrally on the peristomium, continuing into a heavily ciliated esophagus, mid- and hindgut. The anus is located dorsally on the pygidium. A minimum of three pairs of segmental protonephridia are present. Both coelom and a blood vascular system were undetected, but coelenchyme cells are scattered throughout the body. Gonochoristic and sexually monomorphic. Females carry oocytes in the posterior segments and a pair of ventral gonopores near the pygidium. Males carry filiform spermatozoa, an unpaired copulatory organ and several ciliated glandular pores near the pygidium. A larval stage seems to be lacking and direct development is assumed.

Editor's comment  In the Dinophilidae section of Handbook of Zoology volume 1 Westheide (2019) proposed the new family Apharyngtidae with these words: "The erection of a new family taxon Apharyngtidae thus seems to be necessary (see Chapter 7.1.2)". However, the following section 7.1.2 only uses 'Apharyngtus' the genus name as its heading, with no mention of Apharyngtidae, so perhaps the intention to create a new family was dropped during production of the book. [details]
