Etymology Not stated. The name Dispio seems to be composed by the Latin prefix dis-, meaning 'not', 'apart', or 'away', followed by the name of the genus Spio Fabricius, 1785, and presumably refers to the fact that in spite of grossly resembling Spio, the new genus differs from it in some features, such as in having accessory branchial lobes and anterior serrated notopodial lobes.  [details]

Diagnosis Emended diagnosis by Blake (1983: 213-214): "Prostomium fusiform, anteriorly pointed, with narrow caruncle extending posteriorly. Eyes present or absent. Peristomium moderately developed, forming low lateral wings. Anterior parapodial lamellae lobed or entire. Presetal notopodial and neuropodial lamellae present or absent. Branchiae present from setiger 1, fused to notopodial lamellae for half or more of their length. With or without accessory branchiae on posterior face of middle and posterior notopodia. With capillary notosetae only. Neurosetae include capillaries, hooded hooks, and sabre setae. Some capillaries of anterior rows with distinct transverse barring pattern, composed of partitions and chambers in shaft, giving setae cracked appearance; sometimes reticulations interspersed with dense groups of granules. Pygidium with midventral flap and prominent anal cirri.[details]

Diagnosis Original diagnosis by Hartman (1951: 86): ''The prostomium is rounded in front; its caruncle extends back only to the first segment. There are 2 pairs of small, inconspicuous eyes at the sides, largely concealed by the palpal bases. The palpi are paired, large, thick, longitudinally grooved. The lateral margins of the peristomium at the sides of the prostomial ridge, are enlarged to form flanges that extend back to the first setiger. Branchiae are present from the first setiger and continued back to the posterior end; they are more or less fused with the postsetal, notopodial lobe. All parapodia, including the first are biramous. Notosetae are entirely simple, distally pointed. Neurosetae are similarly pointed in anterior segments; farther back some of the pointed setae are replaced by hooded hooks that end distally in an entire point and are hooded. The pygidium ends in a simple, collar-like ring with a slight middorsum notch. From about the twentieth segment there are paired accessory branchial tufts that arise from behind the notopodial base; these tufts have 2 to 5 digitately arranged lobes, each with a vascular loop. The notopodial lobes of the first few segments are enlarged and distally serrated.'' [details]

Etymology Not stated. The name Dispio seems to be composed by the Latin prefix dis-, meaning 'not', 'apart', or 'away', followed by the name of the genus Spio Fabricius, 1785, and presumably refers to the fact that in spite of grossly resembling Spio, the new genus differs from it in some features, such as in having accessory branchial lobes and anterior serrated notopodial lobes.  [details]
