Diagnosis Original diagnosis by Möbius (1874: 254): "Kopf ohne Fühler und Fühlercirren. Das fünfte Körpersegment ist länger als die vorhergehenden und nachfolgenden und enthält jederseits eine kammförmige Reihe dicker Borsten. [...] Kiemen zungenförmig, beiderseits auf dem Rücken der Segmente." [details]
Etymology Leipoceras is composed by the Greek words leipo, meaning 'absent' or 'missing', and ceras, meaning 'horn', and refers presumably to the absence of head tentacles and tentacular cirri: "Kopf ohne Fühler und Fühlercirren" (Möbius, 1874: 254). [details]
Synonymy Fauvel placed L. uviferum under Polydora coeca (Örsted, 1843) (as 'caeca'). As Leipoceras is monotypic the genus name becomes effectively a synonym of Dipolydora currently, although Leipoceras is an older genus name, because the type species of the genus is invalid as a junior subjective synonym of a much older species. If this was not the situation Leipoceras might in any case be a disused name. Probably (not checked) this synonymy had been identified earlier than Fauvel 1927. [details]
