Remarks: Trachycarcinus elegans .is.herein.transferred. to. Trichopeltarion ,.with.which.it.shares.a.unique.combination.of.characters.including:.(i) antennal.setae.dispersed. all. around. antennal. peduncle. (articles. 2+3,. 4-5). and. flagellae,.setae.of.opposing.sides.of.flagellum.forming.incipient.antennal.conduit.at.most;.(ii) infraorbital.tooth. separated.from.the.antennal.articles.2+3.by.a.deep,.wide. gap;.(iii) antennal.articles.2+3.in.close.contact.to.but.not. fused.with.the.lateral.rostral.tooth;.(iv) antennal.articles. 2+3,.4,.and.5.of.about.the.same.length;.(v) mandibular. palp.2-articulated,.with.articles.1-2.completely.fused.to. one.another.and.no.line.of.suture.in.between;.(vi) Pl3. pleurobranchiae. two,. anteriormost. shorter;. (vii) male. abdomen.of.six.free.segments.and.telson.

Ng. &. Chan. (1997). obtained. one. male. of. Trichopeltarion elegans .from.northeastern. Taiwan.and. took.the.opportunity.to.elaborate.on.some.variations. between. the. Taiwanese. specimen. and. the. holotype. male.from. Japan..The.following.are.additions.to.the. variations.in.this.species,.as.revealed.by.examination. of.additional.Taiwanese.males.and.females.as.well.as. the. holotype.of. Trichopeltarion elegans . .In.the.Taiwanese.material.some.tubercles.from.protogastric.and.hepatic.regions.of.the.caparace.are.more.acute.in.smaller. specimens;. epigastric. and. protogastric. granule-bearing. tubercles. showing. more. individualized. granules. (granules.coalescent.in.the.Japanese.individuals);.the. protogastric,. meso-. and. metabranchial. tubercles. are. more.numerous.in.larger.individuals;.the.barbs.on.the. hepatic,. first. epibranchial,. and. second. epibranchial. teeth.clearly.well.distinct.(absent.or.poorly.visible.in. the.Japanese.specimens).(figure 20A-F).

Distribution:. Known. from. Japan. and. Taiwan,. between.100.and.787.meters.depth.
