Etymology. This species is dedicated to Marie-Catherine Boisselier of the Muséum nationale d’Histoire Naturelle, Paris, for her support of crustacean research.

Description. Carapace: As broad as long; transverse ridges with dense short setae, and a few scattered moderately long non-plumose setae; cervical groove distinct, laterally bifurcated into anterior and posterior parts. Gastric region with 6 transverse ridges: 1 epigastric ridge unarmed, uninterrupted, and medially convex; 2 protogastric ridges, anterior one usually uninterrupted, unarmed or with parahepatic spine on each side, posterior ridge median, short and arcuate; 1 mesogastric ridge uninterrupted, not extending laterally to base of anteriormost branchial marginal spines; 2 metagastric ridges uninterrupted, not continuing laterally to anterior branchial ridges, posterior ridge scale-like. Hepatic spine present (minute in some small individuals). Anterior branchial region with distinct ridges. Mid-transverse ridge uninterrupted, preceded by cervical groove. Posterior branchial region with 5 transverse ridges, 2 of them uninterrupted. Lateral margins moderately convex medially, with 7 spines: 2 spines in front of, and 5 spines behind, anterior cervical groove; first (anterolateral) spine moderately small, located at same level of lateral limit of orbit, second spine small, at midlength between anterolateral spine and anteriormost spine of branchial margin, with additional spine ventral to between first and second; 2 spines on anterior branchial margin, posteriro spine smaller than anterior spine, and 4 spines on posterior branchial margin. External limit of orbit with spine; infraorbital margin with strong spine. Rostrum 1.7–1.8 times as long as broad, length 0.6 of postorbital carapace length and breadth 0.3 of carapace breadth; distance between distalmost lateral incisions 0.35 distance between proximalmost lateral incisions; dorsal surface nearly horizontal in lateral view, with numerous small scale-like setose ridges; lateral margin with 4 deeply incised teeth.

Pterygostomian flap rugose, unarmed, ridges with short setae, anterior margin acutely pointed.

Sternum: As long as broad, lateral extremities gently divergent posteriorly.

Abdomen: Somites 2–4 each with 2 uninterrupted transverse ridges on tergite; somites 5 and 6 each with 2 medially interrupted ridges, posteromedian margin of somite 6 straight. Males with G1 and G2.

Eyes: Ocular peduncles 1.6 times longer than broad, maximum corneal diameter 0.7 rostrum width.

Antennule: Article 1 with 3 well-developed distal spines, distodorsal larger. Ultimate article with a few short fine setae not in tuft on distodorsal margin.

Antenna: Article 1 with ventral distomesial spine exceeding distal margin of article 2. Article 2 with 2 distal spines, distolateral spine longer than distomesial and reaching midlength of article 3. Articles 3 and 4 unarmed.

Mxp3: Ischium with flexor margins ending in small spine, extensor margin ending in acute angle; crista dentata with 20 or 21 denticles. Merus shorter than ischium; flexor margin with 2 spines, proximal spine slightly longer than distal; extensor margin ending in acute point. Carpus unarmed.

P1: 3.0–3.5 times carapace length, with numerous setiferous scales, and some scattered long non-plumose setae. Merus 1.2 times carapace length, 1.6 times as long as carpus, with some spines, dorsomesial and distal spines stronger than others. Carpus 0.8 length of palm, 1.5 times as long as broad; dorsal surface with some small spines; mesial margin with row of spines, distal second spine stronger than others. Palm 1.6 times longer than broad; small spines arranged in dorsal, dorsolateral and dorsomesial rows. Fingers 0.7 times palm length, each finger with 2 rows of teeth distally spooned; fingers unarmed.

P2–4: long and slender, with some setose striae and sparse long plumose and non-plumose setae. P2 1.9–2.1 times carapace length. Meri successively shorter posteriorly (P3 merus 0.9 length of P2 merus, P4 merus 0.8 length of P3 merus); P2 merus 0.6–0.8 times carapace length, 4.0–4.5 times as long as broad, 1.5 times longer than P2 propodus; P3 merus 3.5 times as long as broad, 1.5 times longer than P3 propodus; P4 merus 2.9–3.1 times as long as broad, as long as P4 propodus; extensor margins each with row of 8 or 9 proximally diminishing spines in P2–3, 0–1 spines in P4; ventral margins distally ending in strong spine, and 1 or 2 additional distal spines, lateral sides with 1 or 2 spines on P4 only. Carpi each with 2–4 spines on extensor margin in P2–3, unarmed in P4; lateral surfaces each with 3 or 4 small spines or granules sub-paralleling extensor margin; flexor distal margins acute. Propodi 3.4–4.2 times as long as broad; extensor margins unarmed; flexor margins each with 4–6 slender movable spines, terminal 2 paired with another smaller spine mesial to it. Dactyli distally ending in noticeably curved strong spine, 0.5–0.6 times as long as propodi; flexor margins each with 5 or 6 proximally diminishing teeth, terminal one prominent.

Epipods present only on P1.

Remarks. Galathea boisselierae n. sp. is very close to G. patriciae n. sp. from Wallis and Futuna and G. providentia Laurie, 1926 from the SW Indian Ocean and Western Pacific, from the Philippines, to New Caledonia, and Fiji (see differences among the three species under Remarks of G. providentia ). The specimens from the South China Sea and illustrated by Dong & Li (2010) agree quite well with the present new species. However, further studies should confirm the identity of this material.

Distribution. Philippines, Indonesia (Makassar Strait), New Caledonia, 10–215 m, on sponges, on Acropora spp., eunicid polychaete tubes, and crinoids.
