A revision of "blanket-hermit crabs" of the genus Paguropsis Henderson, 1888, with the description of a new genus and five new species (Crustacea, Anomura, Diogenidae) ArchiMer
Lemaitre, Rafael; Listyo Rahayu, Dwi; Komai, Tomoyuki.
For 130 years the diogenid genus Paguropsis Henderson, 1888 was considered monotypic for an unusual species, P. typica Henderson, 1888, described from the Philippines and seldom reported since. Although scantly studied, this species is known to live in striking symbiosis with a colonial sea anemone that the hermit can stretch back and forth like a blanket over its cephalic shield and part of cephalothoracic appendages, and thus the common name "blanket-crab". During a study of paguroid collections obtained during recent French-sponsored biodiversity campaigns in the Indo-West Pacific, numerous specimens assignable to Paguropsis were encountered. Analysis and comparison with types and other historical specimens deposited in various museums revealed the...

Carcinization in the Anomura – fact or fiction? I. Evidence from adult morphology Naturalis
McLaughlin, Patsy A.; Lemaitre, Rafael.
Carcinization, or the process of becoming a crab, has been, and continues to be, a focal point of anomuran evolutionary hypotheses. Traditional examples of carcinization in the Anomura are most celebrated among hermit crabs but certainly are not limited to this group. Carcinization, if it has occurred, has done so independently in all major anomuran taxa. In this critique, the traditional examples of carcinization in the Anomura are reviewed and more modern variations on the theme assessed. Potential pathways of carcinization are examined from perspectives of adult morphology in the Paguroidea, Galatheoidea, Hippoidea and Lomoidea, with emphasis on the Paguroidea. Specific attention is given to the theoretical transformation of a hermit crab-like body form...

Carcinization in the Anomura – fact or fiction? II. Evidence from larval, megalopal and early juvenile morphology Naturalis
McLaughlin, Patsy A.; Lemaitre, Rafael; Tudge, Christopher C..
In this second of a two-part series, carcinization in the Anomura has been reviewed from early juvenile, megalopal, and larval perspectives. Data from megalopal and early juvenile development in ten genera of the Lithodidae have provided unequivocal evidence that earlier hypotheses regarding evolution of the king crab pleon were erroneous. A pattern of sundering, and decalcification has been traced from the megalopal stage through several early crabs stages in species of Lithodes and Paralomis, with supplemental evidence from species in eight other genera. Of major significance has been the attention directed to the marginal plates of the second pleomere, which when separated in lithodids are not homologous with the adult so-called “marginal plates” of the...

Crustáceos anfípodos (Gammaridea) Colectados en las Costas del Caribe colombiano, al sur de Cartagena OceanDocs
Ortiz, Manuel; Lemaitre, Rafael.
Como resultado de investigaciones sobre la fauna de crustáceos de las costas del Caribe colombiano, numerosas muestras se obtuvieron en estaciones localizadas al sur de Cartagena, durante los meses de marzo y julio de 1991. El estudio cualitativo de estas muestras reveló la existencia de 43 especies de anfípodos, de las cuales 25 (58%) no habían sido registradas anteriormente de estas costas. Se presenta una lista sistemática de las especies, así como información sobre el tipo de substrato donde se encontraron. La mayoría se colectaron en habitáts de praderas de fanerógamas marinas (Thalassia, Syringodium). Comparando con otras áreas del Caribe, y teniendo en cuenta la limitación casi exclusiva de los muestreos a estos habitáts, el número de especies...
