A new species of freshwater crab the genus Potamonemus Cumberlidge & Clark, 1992 is described from Mount Manengouba Reserve and Bakossi National Park in tropical rainforests southwestern Cameroon, Central Africa. man sp. nov. recognized by characters carapace chelipeds. In addition, a phylogenetic analysis based on partial sequences three mitochondrial DNA genes (COI, 12S rRNA, 16S rRNA...

A new genus and species of potamid crab, Gurumon gurumayum gen. et sp. nov., are described from the Arunachal Pradesh State northeastern India. nov. has affinities with Abormon Mitra, Pati & Ng, 2021, Pararanguna Dai Chen, 1985, some Potamiscus Alcock, 1909, but can easily be differentiated them mainly by its low external orbital angle, relatively stouter exopod third maxilliped, broader ma...

A copper/zinc superoxide dismutase (Cu,Zn-SOD) cDNA was cloned from the hepatopancreas of giant freshwater prawn Macrobrachium rosenbergii using reverse transcription-polymerase chain reaction (RT-PCR) by degenerate primers. Both 3'- and 5'-regions were isolated by the rapid amplification of cDNA ends method. Analysis of nucleotide sequence revealed that the Cu,Zn-SOD cDNA clone consists of 845...

In Korea, many people enjoy eating raw or underkooked freshwater crayfish and crabs which unfortunately may cause paragonimiasis. Here, we describe a case of pulmonary and abdominal paragonimiasis in a 9-year-old girl, who presented with a 1-month history of abdominal pain, especially in the right flank and the right inguinal area, with anorexia. A chest radiograph revealed pleural effusion in ...

Invasive alien aquatic species, including marine and freshwater macroinvertebrates, have become increasingly important in terms of both environmental and socio-economic impacts. In order to assess their environmental and economic costs, we applied the Generic Impact Scoring System (GISS) and performed a comparison with other taxa of invaders in Europe. Impacts were scored into six environmental...
