Prosadenoporus floridensis, Maslakova & Norenburg, 2008

Maslakova, Svetlana A. & Norenburg, Jon L., 2008, Revision of the smiling worms, genera Prosadenoporus Bürger, 1890 and Pantinonemertes Moore and Gibson, 1981 and description of a new species Prosadenoporus floridensis sp. nov. (Prosorhochmidae; Hoplonemertea; Nemertea) from Florida and Belize, Journal of Natural History 42 (25 - 26), pp. 1689-1727 : 1692-1693

Family: PROSORHOCHMIDAE Bürger, 1895

Diagnosis

Monostiliferous, marine, brackish-water, semi-terrestrial or terrestrial hoplonemerteans with rhynchocoel extending most or all the body length, body wall containing distinct outer circular and inner longitudinal muscle layers and a delicate layer of diagonal muscles between; longitudinal musculature may appear to be anteriorly divided (i.e. some of the proboscis insertion muscles may be oriented obliquely and longitudinally); four simple eyes; proboscis may be small or large, and sometimes used in locomotion; stylet basis in most species characteristically truncated; head in most species with characteristic dorsal horizontal epithelial fold (the prosorhochmid smile); cerebral sensory organs anterior or anterolateral to brain, with simple unbranched cerebral canals, in most species opening ventro-laterally via reduced cerebral organ furrows; cephalic glands well developed, with distinct granular proteinaceous components (orange-G and acidophilic glands) in addition to basophilic mucus lobules; frontal organ represented by an exceptionally welldeveloped tubular canal, typically with laterally specialized epithelium; middorsal blood vessel with a single vascular plug; typically gonochoric and oviparous, occasionally hermaphroditic and viviparous.

Composition

As a result of our proposed synonymization of Pantinonemertes Moore and Gibson, 1981 with Prosadenoporus Bürger, 1890 the family now contains three genera:
