“…I). However, most studies did not consider the developmental stage of the eggs, which impedes a comparison of the published values: egg size in decapods tends to increase during the incubation period (WEHRTMANN & KATTNER 1998, YAMAGUCHI 2001, WEHRTMANN & LÓPEZ 2003, PAVANELLI et al 2008, and this increase is typically related to the incorporation of large amounts of water (PANDIAN 1970). In contrast, MANSUR & HEBLING (2002) mentioned that the egg diameter of D. pagei and S. australis did not vary during embryogenesis.…”

Freshwater crabs are an important component of the fauna of limnic environments, and out of the two true freshwater crab families present in the Neotropics, Pseudothelphusidae is the most diverse. Considering the lack of information regarding reproductive features of neotropical freshwater crabs, we studied, for the first time, the fecundity and the presence of juveniles carried by females of two pseudothelphusids from the Amazon region - Kingsleya latifrons (Randall, 1840) and Kingsleya ytupora Magalhães, 1986 - and one from Central America - Potamocarcinus magnus (Rathbun, 1896). The two Kingsleya species produced relatively few (56-114) and large eggs (1.9-3.7 mm), typical for species with an abbreviated or direct development. Recently produced eggs were substantially larger in K. latifrons (mean 2.83 mm) when compared to those of K. ytupora (mean 1.87 mm); however, at the end of the embryogenesis, mean egg diameter was similar in both species. Therefore, it is assumed that hatchlings in both species should have a similar size. A brief description of attached juveniles of K. ytupora is provided. The number of juveniles varied between 30 (K. ytupora) and 179 (P. magnus); two size groups of juveniles were found, which indicates that the offspring cling to their mother for a prolonged period of time. There was no significant loss of eggs and juveniles; it is assumed that parental care diminishes the loss of their offspring. We compiled the available information of reproductive aspects from freshwater crabs: egg diameter was in the range of 2-3 mm, independent of female size and fecundity, and reported egg number varied between 9 and 417 eggs

“…Following a revision of the western-Atlantic species within this complex, the distribution of the sensu stricto form is presently understood to extend only from southern Florida to Venezuela (Anker, 2012). Some of the previous records of this shrimp in Brazil have been assigned to A. angulosus (Coelho and Ramos, 1972;Christoffersen, 1998;Coelho et al, 2006, in part) and A. carlae (Holthuis, 1956;Mossolin et al, 2006;Pavanelli et al, 2008) (see Anker, 2012). The material reported by Almeida et al (2006Almeida et al ( , 2007aAlmeida et al ( , 2012) from the coast of Bahia was re-examined by us and corresponds to A. carlae and A. angulosus.…”

Time calibrated phylogenies are typically reconstructed with fossil information but for soft‐bodied marine invertebrates that lack hard parts, a fossil record is lacking. In these cases, biogeographic calibrations or the rates of divergence for related taxa are often used. Although nudibranch phylogenies have advanced with the input of molecular data, no study has derived a divergence rate for this diverse group of invertebrates. Here, we use an updated closure date for the Isthmus of Panama (2.8 Ma) to derive the first divergence rates for chromodorid nudibranchs using multigene data from a geminate pair with broad phylogeographic sampling. Examining the species Chromolaichma sedna (Marcus & Marcus, 1967), we uncover deep divergences among eastern Pacific and western Atlantic clades and we erect a new species designation for the latter (Chromolaichma hemera sp. nov.). Next, we discover extensive phylogeographic structure within C. hemera sp. nov. sensu lato, thereby refuting the hypothesis of a recent introduction. Lastly, we derive divergence rates for mitochondrial and nuclear loci that exceed known rates for other gastropods and we highlight significant rate heterogeneity both among markers and taxa. Together, these findings improve understanding of nudibranch systematics and provide rates useful to apply to divergence scenarios in this diverse group.
