Description. Average length (head anterior margin to telson posterior margin): 7.4 mm (range 6.2 - 8.7 mm) in males; 7.9 mm (range 6.2 - 10.2 mm) in females. Holotype male. Body red or jacinth in life (Fig. 1 C). Head typical for genus. Eye plus peduncle length subequal to first antenna length. Eye large, width> 0.2 x second antennal proximal antennomere medial width. First antenna long, filiform, extending to second antennae distal antennomere midlength, apex with five or six aesthetascs. Antennal appendage lamellar, directed anteromedially, apex broadly triangular (Figs 2 A, 3 E). Appendage basal portion inerm, distal portion bearing conical spinulae arranged in two or three marginal rows. Anterior surface with scattered, large, anteriodistally directed spines. Each anterior surface spine conical, 2 - 3 x lateral spinulae. Second antenna extending to thoracopod IV or V (Fig. 1 C). Second antenna proximal antennomere (Fig. 3 A) subcylindrical, length nearly 1.5 x breadth. Posteriolateral surface with medial patch bearing ~ 10 setae (Fig. 3 B). Lateral surface with rings composed of four or five micropapillae surrounding a single filiform seta (Fig. 3 C). Anteromedial surface with denticulae and sparse setae (Fig. 3 E). Anterior surface with five or six rows of setae, with groups of scattered micropapillae arranged as on lateral surface (Fig. 3 F). Distal antennomere laterally compressed, length ~ 1.5 x proximal antennomere. Distal antennomere narrowing to medial bend ~ 70 ° at proximal third of antennomere length (Figs 2 A, 3 A, G). Just proximad to bend, medial surface with hemispherical protuberance covered in fine denticulae (Fig. 3 A, H). Distal two-thirds parallel-sided with remainder straight to apex which is medially bent ~ 35 ° (Fig. 3 A). Anterior margin with triangular projection midway between bend and apex. Apex subacute (Fig. 3 A, I). Thoracic segments dorsally smooth (Fig. 1 C). Thoracopod I with praeepipodite divided, proximal portion oval, distal portion elongate-oval, both with margins inerm and smooth. Epipodite lamellar, length ~ 2 x width, apex angular. Exopod elongate oval, length

Diagnosis. Typical for genus. Male antennal appendage lamellar, subtriangular, apically subacute (Fig. 3 E). Second antenna proximal antennomere lacking lateral hemispherical bulge. Second antenna distal antennomere medial surface with subproximal rounded protrusion covered in spinulae (Fig. 3 H). Genital segment medial lamellar projection with medial longitudinal lines of spinulae elevated on crests (Fig. 3 K).

Etymology. The specific epithet " shangrilaensis " refers to the species being from Shangri-La County. The gender is feminine.
