Discovered two new freshwater crab species in the North

Scientists at the Institute of Ecology and Biological Resources under the Vietnam Academy of Science and Technology have discovered two new freshwater crab species in the mountains of northern Vietnam.

The first species, Indochinamon chuahuong Do , Nguyen & Le , was discovered in Huong Pagoda, in Huong Son commune, My Duc district, Hanoi. This species is separate from other known species in a variety of traits such as apricot which has a longer width than the length, the front edge is protruding, and the serration is clearly visible; the bearing area is slightly convex when viewed from the dorsal surface; The legs are relatively long. The end of the G1 is curved outwards, with a very low back crest. The article describing this species was published in the international journal Raffles Bulletin of Zoology.

Crab species named Indochinamon chuahuong Do, Nguyen & Le have just been discovered in Huong Pagoda, My Duc district, Hanoi.

The second species of crab was discovered named Tiwaripotamon pluviosum , found in Ban Coong, Duc Quang commune, Ha Lang district, Cao Bang province of Vietnam and Nonggang Nature Reserve, Long Chau district, Sung Ta city, Guangxi province of China.

New crab species named Tiwaripotamon pluviosum in Cao Bang.

This species is distinguished from other species in the breed through a number of characteristics such as relatively flat apricot, relatively thin cow legs and with back crests at the tip of G1 male boar. This new species is also in the Raffles Bulletin of Zoology magazine, No. 64, page 213-219, August 2016.

According to scientists, the two new species of crabs are distributed in the limestone mountains of northern Vietnam and the Vietnam-China border area. This is one of the very special habitats and species that live in it are mostly endemic species and have very limited distribution areas. The discovery of these new freshwater crab species further shows the potential and biodiversity value of limestone karst areas in Vietnam.
