description: <i>Halosydna virgini</i> Kinberg, 1856 (Figure 23) <i>Halosydna virgini</i> Kinberg, 1856: 384; Kinberg, 1858: 15–16; Seidler, 1924: 120; Hartman, 1938: 109. <i>Type material</i> Holotype (SMNH-Type 410), Honolulu, Hawaii Island, 21 ◦ 19 ′ N, 157 ◦ 52 ′ W, leg Eugenie, Expedition 1851–53. <i>Description</i> Holotype incomplete; an anterior fragment with 19 segments, yellow-pale. Prostomium in poor condition. Seven pairs of elytra attached, overlapping. Elytra margins with thick, long papillae (Figure 23A,B), surfaces covered with conical microtubercles (Figure 23C), some truncate and others pointed. Notopopodia shorter than neuropodia (Figure 23D). Neuropodia distally truncate, prechaetal and postchaetal lobes indistinct, prechaetal lobe with small rounded lobe near acicular tip. Dorsal cirri detached. Cirrophores basally expanded. Elytrophores wider than dorsal tubercles. Ventral cirri tapering to filiform tip. Notochaetae shorter than neurochaetae, with rows of spines; the smaller chaetae shorter, curved, blunt tips; the remaining notochaetae slender tapering to capillary tips (Figure 23F). Neurochaetae with rows of spines on upper region; bidentate tips, main tooth curved, subdistal tooth short (Figure 23E). <i>Remarks</i> The species, known from Hawaii, was originally described as having 35 segments, 18 pairs of elytra and bidentate neurochaetae. However, it was synonymized with <i>Halosydna parva</i> from Peru (Hartman 1949). Despite the present condition of the holotype, its features are clear: elytra margins with long papillae thicker than in <i>H. parva</i> and elytra lack the thick macrotubercles present in this species. Therefore, it must be considered a valid species. <i>Type locality</i> Honolulu, Hawaii Island, 21 ◦ 19 ′ N, 157 ◦ 52 ′ W. <i>Distribution</i> Same as type locality.
