Original localities.

Stations 9, 20, 47, 48, 76, 81, 107, 109, 121, 145, 156, 165, 170, 175, 176, 178, 179, 184 (490 - 900 m) (Red Sea; Table 1 ). In the original description Sturany did not refer to any particular station. Therefore, it is assumed that the whole material listed in 1903 constitutes the type material as listed below.

Type material.

Figured syntypes: NHMW 84146 (station 9): 1 specimen, illustrated by Sturany (1903) in plate I, figure 4a; NHMW 84171 (station 175): 1 specimen, reported on label that this specimen is illustrated by Sturany (1903) in plate I, figure 2a, height 113 mm.

Further syntypes: NHMW 84149 (station 20): 2 specimens; NHMW 84151 (station 20): 1 specimen; NHMW 84154 (station 76): 1 specimen; NHMW 84155 (station 76): 5 specimens; NHMW 84156 (station 81): 1 specimen; NHMW 84164 (station 165): 1 specimen; NHMW 84165 (station 165): 1 specimen; NHMW 84172 (station 176): 1 specimen; NHMW 84173 (station 176): 1 specimen; NHMW 84175 (station 179): 3 specimens; NHMW 84176 (station 179): 3 specimens; NHMW 84177 (station 179): 2 specimens; NHMW 84178 (station 179): 1 specimen; NHMW 84179 (station 184): 1 specimen. Two more specimens are present without labels and inventory numbers, they probably come from stations 47 and 178.
