Head longer than wide, 495 X 385 µm (not including inflated antennule), with small rounded knob at each anterolateral corner and distinctly swollen oral region. First pediger forming neck region. Second pediger fused with remaining prosomal somites into a long, cylindrical trunk. Genital double somite distinctly wider than long, with abdomen attaching to it like a narrow ring. Caudal ramus a spiniform pointed process bearing three setae and a tubercle. Antennule fleshy, with inflated base tipped with a short, setae-bearing process; armature being (from proximal to distal) 1-1-1-2-2-8. Antenna two-segmented; terminal segment sharply curved, with annular sculptures in bent area. Labrum with postero-lateral knob and smooth posterior margin. Terminal blade of mandible bearing 22 to 24 teeth on convex (inner) side and 13 to 16 teeth on concave (outer) side. Maxillule with two terminal elements and a subterminal process tipped with three tubercles. Maxilla two-segmented; first segment robust and unarmed; second segment bearing one small, simple seta, one large seta with hyaline tip and a row of 14 to 18 teeth on terminal process. Maxilliped three-segmented; constructed roughly as in Bactrochondria papilla with subchelate appearance.
