New crabs (Decapoda: Brachyura: Prosopidae) from Jurassic (Oxfordian) sponge bioherms of Dobrogea, Romania

چکیده
A previously undescribed fauna of primitive brachyurans of the family Prosopidae is reported from sponge bioherms in eastern Romania. One new species, Cycloprosopon dobrogea, and several other forms, constitute the brachyuran fauna. The sponge bioherms, which attain a height of 30 meters, have yielded an abundant, but not overly diverse, array of benthic invertebrates. Some of the brachyuran specimens bear epibionts, unusual in the fossil record of the Decapoda. The constitution of several genera within the Prosopidae is herein summarized in order to facilitate further work on the family within the context of modern systematic methods.

Examination of Jurassic decapod crustaceans associated with microbialite-siliceous sponge biostromes in Gura Dobrogei, eastern Romania, has yielded a unique association of these organisms. Goniodromites aliquantulus new species appears to have inhabited layered sponge biostrome settings only, whereas Cycloprosopon dobrogea and Goniodromites spp. appear to have inhabited a variety of microbialit...

Adult female crabs (Potamonpersicum; n=65) were collected from the Jajrood River in the east of Tehran, Iran. Both eyestalks were removed in crabs that weighed 27.6 ± 2.1 g. Changes in the levels of glucose and protein titers in the hemolymph, the number of hemocytes, gonadal and hepatic indices, body weight and carapace length were determined. The level of glucose in the hemolymph was signific...

Cymonomid crabs collected from the Mozambique Channel off Madagascar by the 2011 MAINBAZA Expedition are reported. Two species of Cymonomus A. Milne Edwards, 1880, are represented, of which one is new to science and the other, C. valdiviae Lankester, 1903, is rediscovered, being previously known only from the holotype. Three species of Cymonomidae are now known from the western Indian Ocean, in...

Pseudopalicus bidens (Brachyura, Palicidae) is described as a new species from the Andaman Sea, on the western coast of Thailand. The new species can be distinguished from its congeners by its anterolateral teeth on each side of the carapace, with the first two being considerably larger than the last two, as well as for morphology of the gonopods. The new species will bring the number of descri...
