Original localities. Stations 48 (700 m) and 143 (212 m) (Central and Southern Red Sea; Table 1 ). Type material. Illustrated syntype: NHMW 84254 (station 143), illustrated by Sturany (1903) in plate III, figures 2 a-c, height 8 mm. Further one syntype NHMW 84253 (station 48). Original description. Schale reinweiss , abgestutzt spindelfoermig , aus 9 Umgaengen bestehend. Die Embryonalwindungen glatt, die uebrigen gegittert und knotig sculptiert; ein median angelegter, dominierend breiter, geperlter Spiralreifen, eine naechst der Naht verlaufende schwaechere Knotenreihe und 1 bis 2 feinste Spirallinien ober und unter der Mitte (auf dem letzten Umgange sind es naturgemaess deren mehr) werden naemlich von den zahlreichen quer und bogig ueber die Umgaenge gestellten Laengsrippen gekreuzt. Muendungsrand scharf, mit zungenfoermigem Ausschnitte naechst der Naht und halbkreisfoermiger Bucht an der Basis. Hoehe der Schale 7,1 und 8,4 mm, Breite 2,7 und 3,1 mm; Muendungshoehe 2,6 und 3,0, Muendungsbreite 1,2 und 1,4 mm. Von den Stationen 48 (700 m) und 143 (212 m) je ein Exemplar. Die neue Art ist gewissermassen eine Miniaturausgabe von Pleurotoma radula Hinds. Figure 24. Pleurotoma nannodes Sturany, 1900, Station 143 (Harmil Island, Dahlak Archipelago, Eritrea, Red Sea). A-E, G . Figured syntype, NHMW 84254: front ( A-B ), right side ( C-D ), back ( E ), protoconch ( G ). F . Original figure by Sturany (1903) . H . Original label. Scale bars: A-E : 1 mm, G : 0.2 mm. Translation. Shell pure white, truncate fusiform, composed by nine whorls. Protoconch smooth, the other whorls with a reticulated and tubercled sculpture; a median, prominent, wide, tubercled spiral thread; closer to the suture, there are weaker tubercled threads and one or two fine spiral lines above and below the median prominent spiral thread (on the last whorl there are naturally more); the spiral sculpture is crossed by numerous curved axial ribs. Lip sharp, with tongue-shaped posterior siphonal canal next to the suture and a semi-circular anterior canal at the base. Height of shells is 7.1 mm and 8.4 mm, width 2.7 mm and 3.1 mm; mouth height 2.6 mm and 3.0 mm, mouth width 1.2 mm and 1.4 mm. From each of stations 48 (700 m) and 143 (212 m) one specimen. The new species is a kind of miniature version of Pleurotoma radula Hinds. Comments. This species was assigned to the genus Paradrillia Makiyama, 1940 by Orlin and Dekker (2000: 32) and Janssen in Janssen and Taviani (2015 : 526); it looks like Paradrillia melvilli Powell, 1969, which could be a junior synonym.
