Name

Hemilamprops normani Bonnier, 1896 – Wikispecies link – Pensoft Profile

• Hemilamprops normani – Bonnier 1896^[1], pp. 546–549, pl. 29 fig. 3.
• Hemilamprops cristata – Calman 1905^[2], p. 41, 49 [nec Hemilamprops cristata (Sars, 1870)].

Material examined

Cap Ferret Canyon, Bay of Biscay, ESSAIS II: stn TS10, 44°33.10'N, 2°13.13'W, 791–790 m, 18/05/89, 3 mancas, 2 pread. female, 1 ad. male; stn TS11, 44°32.89'N, 2°14.24’W, 923–924 m, 18/05/89, 6 mancas, 2 pread. males; stn TS13, 44°34.19'N, 2°16.18'W, 1097–1099 m, 17/05/89, 4 mancas, 2 imm. males. J.-C. Sorbe leg.

Remarks

Although Calman (1905)^[2] suggested the synonymy between Hemilamprops cristatus and Hemilamprops normani, other authors (Sars 1900^[3]; Hansen 1920^[4]; Fage 1929^[5], 1940^[6]) consider them as valid species, which is the criterion followed here. It is possible that the presence of Mesolamprops denticulatus in the Bay of Biscay, together with the two species of Hemilamprops, led to the confusion between these three species. Hemilamprops normani can be distinguished from the other two species by its higher number of lateral setae on the telson (6–8). Moreover, the three terminal setae of the telsonof Hemilamprops cristatus are of the same length, while in Hemilamprops normani the central one is the longest.

Distribution

Hemilamprops normani is known to inhabit the waters of the Bay of Biscay (Bonnier 1896^[1]; Jones 1985^[7]), the west of Ireland (Calman 1905^[2]), the Azores Islands (Fage 1929^[5]) and the Mediterranean Sea (Fage 1940^[6]; Reyss 1974b^[8]). According to Jones (1985)^[7], in the Bay of Biscay this species inhabits bottoms between 280 and 3000 m. This wide bathymetric range, however, should not be assumed with complete certainty, since it is possible that Hemilamprops normani has been confused with Hemilamprops denticulatus, at least in its most shallow distribution. During this study Hemilamprops normani was always collected in waters deeper than 700 m.
