DESCRIPTION
Carapace as long as wide. Dorsal surface with many short striae, without complete transverse ridges. Striae with few, short, non-iridescent setae. Gastric region with two pairs of epigastric spines; postcervical spine on each side. Frontal margins slightly oblique. Lateral margins slightly convex. Anterolateral spine short, at anterolateral angle, not reaching level of sinus between rostrum and supraocular spines. Second marginal spine before cervical groove slightly smaller than preceding spine. Branchial margins with five spines, third spine small. Rostrum spiniform, short, about one-third as long as remaining carapace, straight and horizontal. Supraocular spines reaching mid-length of rostrum and not reaching end of corneae, subparallel, and horizontal (
Fig. 3A
).
Thoracic sternites smooth. Anterior part of fourth sternite clearly narrower than third (
Fig. 3B
).
Second abdominal somite unarmed on anterior ridge. Second and third somites each with one transverse stria.
Eyes small, barely wider than eyestalk, maximum corneal diameter less than one-fourth distance between bases of anterolateral spines.
Basal segment of antennule (distal spines excluded) about one-third carapace length, elongate, clearly exceeding end of corneae, with two distal spines, mesial spine distinctly shorter than lateral; three spines on lateral margin, proximal two short, located at mid-length of segment, distal one long, clearly not reaching end of distal spines
