The Pylojacquesidae are a small family of hermit crabs, comprising only two [1] monotypic genera. [2] [3] The family was erected in 2001, after two specimens at Museum für Naturkunde at the Humboldt University of Berlin were recognised as being quite distinct from other described hermit crabs. [4] The family members differ from other hermit crabs in that their mandibles are chitinous and toothed. [5]
Pylojacquesia is monotypic, the sole species being Pylojacquesia colemani. [3] It was described in 2001, [4] based on two specimens discovered in the Museum für Naturkunde. The specimens had been collected in 1875 by the S.M.S. Gazelle at 26°51.1′S 153°29.6′E / 26.8517°S 153.4933°E in the Coral Sea, off the coast of Brisbane, Australia. It lives in the tubes secreted by serpulid worms of the genus Protula ( Annelida: Serpulidae) in sandy areas of the continental shelf. [5] The specific name commemorates Charles Oliver Coleman, curator of Crustacea at the Museum für Naturkunde. [4]
Lemaitreopsis is monotypic, the sole species being Lemaitreopsis holmi. [2] It was described in 2007, based on a single female collected on September 20, 1986, at 22°40.39′S 167°41.39′E / 22.67317°S 167.68983°E near the Isle of Pines, New Caledonia. [6] The genus name Lemaitreopsis commemorates Rafael Lemaitre of the Smithsonian Institution, while the specific name commemorates the malacologist George P. Holm. [6] The holotype is kept at the Muséum national d'histoire naturelle in Paris. [6]
