Thomas , 14 February 1989 (JDT/ OPH 11 ) . Paratypes : female, 1B, 5.6 mm , 3 slides, AM P75493, same station data ; 14 specimens ( 4 males , 10 females ), AM P75494, same station data . Type locality . Reef front, northern-most bay, Fantome Island , Queensland , Australia (~ 18°41'10''S 146°31'08''E ) . Etymology. Eumilli is the indigenous name for Fantome Island, the type locality. Description . Based on holotype , male, 4.5 mm , AM P75492. Head. Head with lateral keel; rostrum without apical constriction. Eyes present. Antennae 1 article 2 elongate, greater than 1.1 times article 1; flagellum with 6 articles; accessory flagellum 2-articulate. Antennae 2 brush setae present (in male); flagellum with 39 articles. Upper lip subovoid, apically rounded. Mandible accessory setal row absent; mandibular molar subovoid, large, (covering more than 1/2 of medial surface); mandibular palp article 2 subequal to article 3, article 2 with 1 seta, article 3 with apical and medial setae. Lower lip mandibular lobes weakly produced, apically rounded, with lobes directed posteriorly. Maxilla 1 palp short, extending to end of outer plate, with 3 apical setae; inner plate setae absent. Maxilla 2 outer plate with many apical setae; inner plate with many apical setae. Maxilliped dactylus well developed, articulate. Pereon. Gnathopod 1 chelate; coxa large, similar in size to coxa 2, broader than long, anterior margin produced, apically rounded; carpus longer than propodus, around six times as long as broad; propodus about three times as long as broad, chela short, obtuse projection broader than long. Gnathopod 2 chelate; carpus longer than propodus, six times as long as broad; propodus about three times as long as broad, chela short, obtuse projection broader than long. Pereopods 3–4 articles rectolinear; dactylus simple, long, more than half the length of the propodus. Pereopod 3 coxa expanded distally. Pereopod 4 coxa anterodistal margin not produced, posteroventral lobe absent. Pereopod 5 coxa posterior lobe anterior margin diagonal; basis slightly longer than broad, posterodistal lobe well developed. Pereopod 6 coxa posterior lobe long, extending more than half the length of the basis, with robust setae; basis subovoid; merus about as broad as long. Pereopod 7 basis posterior margin acutely produced; carpus 2 times as long as broad; propodus 5 times as long as broad; dactylus short, less than half the length of the propodus. Pleon. Pleonites 1–3 without dorsal teeth. Epimeron 1 posterodistal corner rounded. Epimeron 2 posterodistal corner with well developed tooth, posteroventral margin without notch. Epimeron 3 posteroventral corner with well developed tooth; posteroventral margin with notch above distal tooth. Uropod 1 peduncle with 7 robust setae. Uropod 2 peduncle with 4 robust setae; inner ramus shorter than outer ramus. Uropod 3 outer ramus article 2 slender, with 4 sets of lateral robust setae. Telson moderately cleft, with dorsofacial robust setae, lateral robust setae present, with 2 pairs of apices, apices subequal. Habitat. Sublittoral sandy bottoms. Remarks. Tomituka eumilli sp. nov . can be differentiated from T. doowi Barnard & Drummond, 1979 by the unconstricted rostrum, which is strongly constricted in T. doowi . The accessory flagellum is 2-articulate in T. eumilli sp. nov . and 8-articulate in T. doowi . The maxilliped, mandibular palp article 2, maxilla 1 palp and maxilla 2 are less setose than those of T. doowi . In T. eumilli . there is no accessory setal row on the left or right mandible. In Tomituka doowi there are three setae in the accessory setal row and a large grinding surface on the adjacent to the incisor, which is not present on T. eumilli sp. nov . In Tomituka eumilli the telson has less robust setae and is not as cleft as in T. doowi . The uropod 3 outer ramus article 2 in Tomituka eumilli is more robust and has lateral robust setae, than the article 2 of T. doowi , which is slender and without setae. Distribution . Australia . Queensland : Lizard Island; Fantome Island; Orpheus Island (current study).
