The extreme morphological similarity among certain species makes very difficult to identify diagnostic characters, and the realdiversity of the group is probably underestimated. Here, two new species of the genus Munida from Taiwan previously identified as M. distiza Macpherson, 1994 and M. militaris Henderson, 1885, respectively, are described and illustrated. The two speciesare identified by subtle and constant morphological differences, which match clear molecular divergences in the 16S and COI genes. These results confirm the taxonomic value of slight morphological differences, and emphasize the need for more detailed analysis to clarify the phylogenetic relationships within the genus.
查看更多>>摘要：Microphilypnus Myers, 1927 is a genus with three nominal species (M. amazonicus and M. macrostoma from the lower Amazon basin, and M. ternetzi from Orinoco), and is among the most poorly studied groups of Neotropical fishes. In this paper, M. ternetziand M. macrostoma are redescribed and validated and M. amazonicus is regarded as synonym of M. ternetzi. Also, a new species, M. acangaquara, is described from the lower Amazon.

This tribe comprises two genera: Sellanucheza Enghoff et al, 2004 and Tonkinosoma Jeekel, 1953, including 6 species distributed in southern China andnorthern Vietnam. Among them, two new species are described from Vietmm, Sellanucheza hoffmani, sp. n., and Tonkinosoma jeekeli, sp. n. A key to all species of Tonkinosomatini and a map of their distribution are also provided for Vietnam fauna.
