Taxonomic Remarks
Only a single damaged female is known. In Heteroserolis MoV7410 coxal dorsal plate 6 extends much more posteriorly than in other species of the genus. Interim diagnosis. Based on female only. Female 1.2 times as long as wide. Body dorsally not setose. Head with 1 low posterior tubercle; pereonites 1–4, pleonites 1–3 each bearing long low median tubercle; pereonites 1–6, pleonities 2, 3 laterally smooth in female. Pereonite 1 anterolateral margins convex. Coxal dorsal plates 1–6 marginally contiguous; coxal dorsal plates 2–4 delimited from pereonite tergites by non-articulating suture; plate 6 well overlapping pleonal epimeron 3, reaching midway along pleotelson. Pleonites 2, 3 epimera margins rounded in dorsal view. Pleotelson lateral margins sinusoidal, tapering from base; 1 times as long as wide; with obscure medial longitudinal carina having slight saddle in middle, with sublateral flat triangular plate, acute posteriorly about half-way along pleotelson; apex concave. Pleonite 1 sternite with prominent keel reaching midway along smaller keel on pleonite 2; pleonite 3 with grooved keel as long as that on pleonite 2. Uropod attaching at 0.45 length of pleotelson lateral margin; endopod reaching almost to pleotelson apex, tapering to rounded apex; exopod three-quarters as long as endopod, apex truncate, crenellate.
