Mitochondrial patterns of intra- and interspecific differentiation among endemic freshwater crabs of ancient lakes in Sulawesi Naturalis
Schubart, C.D.; Santl, T.; Koller, P..
Due to their long-term ecological stability, ancient lakes represent very interesting systems for studying differentiation and speciation processes. High degrees of endemism and specialisation are characteristic features of their fauna. The Malili lakes from the Indonesian island Sulawesi are considered an ancient limnic system, and recent research has increased the number of recognized species and the knowledge about ecological and morphological diversification within a variety of animal taxa. Here we show that the local endemic gecarcinucid freshwater crabs are more differentiated than qualitative morphological characters and the current taxonomy may indicate. The morphologically and ecologically well characterised species Nautilothelphusa zimmeri Balss,...

Monophyly and phylogenetic origin of the gall crab family Cryptochiridae (Decapoda : Brachyura) Naturalis
Meij, S.E.T. van der; Schubart, C.D..
The enigmatic gall crab family Cryptochiridae has been proposed to be phylogenetically derived from within the Grapsidae (subsection Thoracotremata), based on the analysis of 16S mtDNA of one cryptochirid, Hapalocarcinus marsupialis, among a wide array of thoracotremes, including 12 species of the family Grapsidae. Here,wetest the monophyly and phylogenetic position of Cryptochiridae using the same gene, but with an extended representation of cryptochirids spanning nine species in eight of 21 genera, in addition to further thoracotreme representatives. The results show that gall crabs form a highly supported monophyletic clade within the Thoracotremata, which evolved independently of grapsid crabs. Therefore, the Cryptochiridae should not be considered as...
