Holotype ♀, 1.3 mm, P.90987, Coral Sea, Portlock Reef, reef slope, -9.643° 144.828°, 30 m, scuba, Halimeda , 29 Jan 1993, S. J. Keable, QLD 778 , in AM . Paratypes: 1 diss. ♀, P . 90988; 1♀, P .90989.
Etymology. The species bears the name of Dr Bujor Dumitriu (1954–2010), Romanian engineer, specialist in industrial robots, as a sign of pious homage.
Diagnosis. Carapace 0.3 body length; maxilliped 3 basis 0.6 rest of article’s length, propodus 1.4 carpus length; pereopod 2 dactylus, 2nd longest article, 2 propodus length; uropodal peduncle 0.8 of pleonite 6 length, 0.8 of endopod length; endopod 1.4 exopod length.
Description. Carapace 0.3 body length, 1.5 as long as high, smooth; ocular lobe divided; pseudorostral lobes 0.4 carapace length, completely separated; antennal notch with strong anterolateral tooth ( Fig. 50 A, B View Figure 50 ). — Antenna 1 peduncle article 1 0.8 rest of article’s length, with 2 simple setae; article 2 with 3 pedunculate setae; article 3 with 1 simple and 2 pedunculate setae; main flagellum 1.2 article 3 length; accessory flagellum with 1 article; aesthetascs 2 main flagellum length ( Fig. 50 C View Figure 50 ). — Maxilliped 2 basis with 1 pappose seta medially; merus 2.2 ischium length, with 1 plumose seta; carpus 1.1 merus length, with 2 plumose setae; propodus 0.8 carpus length, with 2 simple and 2 penate setae; dactylus 0.5 propodus length, with 1 robust terminal seta ( Fig. 50 D View Figure 50 ). — Maxilliped 3 basis 0.6 rest of article’s length, with 4 plumose setae; merus 4 ischium length, with 2 plumose setae; carpus 1.1 merus length, with 1 simple and 3 plumose setae; propodus 1.5 carpus length, with 10 setulae, 1 plumose and 2 pappose setae; dactylus 0.6 of propodus length, with 1 setule and 4 setae ( Fig. 50 E View Figure 50 ). — Pereopod 1 basis 0.5 rest of article’s length, with 1 simple seta; merus 2.5 ischium length, with 1 simple seta; carpus 2 merus length, with 3 simple setae; propodus 0.7 carpus length, with 4 simple setae; dactylus 0.7 propodus length, with 3 simple setae ( Fig. 50 F View Figure 50 ). — Pereopod 2 basis 0.5 rest of article’s length; merus 5.6 ischium length, with 1 simple seta; carpus 1.4 merus length, with 2 simple setae; dactylus 2 propodus length, with 1 setule and 4 simple setae ( Fig. 50 G View Figure 50 ). — Pereopods 3–5 with decreasing basis and increasing carpus length; dactylus fused with terminal seta ( Fig. 50 H–J View Figure 50 ). — Uropod al peduncle 0.8 of pleonite 6 length, 0.8 of endopod length, with lateral hyaline fringes; exopod with 3 simple setae; endopod 1.4 exopod length, with hyaline fringes, 3 setae medially, 1 simple terminal seta on both rami ( Fig. 50 K View Figure 50 ).
Remarks. Schizotrema dumitriui sp. nov. is closely related to S. nudum Tafe & Greenwood, 1996 in the regarding carapace lacking tubercles or spines. It mainly differs by the uropod longer peduncle and exopod.
Distribution. Coral Sea: Portlock Reef, at 30 m; and Australia: WA—Dampier Archipelago, at 6–14 m depth.
