Three new shrimp species

Werner Klotz and Kristina von Rintelen described three new shrimp species of the genus Caridina from Indonesia.

Caridina boehmeiKlotz & von Rintelen, 2013 and Caridina laroeha Klotz & von Rintelen, 2013 originate from rivers on Central Sulawesi, whereas Caridina butonensis Klotz & von Rintelen, 2013 come from Buton Island.

Caridina boehmei is transparent and has a pattern of white pigments and three black bands. This shrimp is found in only two smaller rivers, on various substrates, amongst others, on rock. It has been introduced into trade under the names „Sulawesi Bee“ or „Mambo Bee“. This shrimp is closely related to C. sulawesi Cai & Ng, 2009, however, the sexual appendages of the males differ from those of the latter.

It is unknown how Caridina laroeha Klotz & von Rintelen, 2013 looks alive. This shrimp species has been named after its type location, Laroeha River in the west of Central Sulawesi, Indonesia, which is, at the same time, hitherto the only known place where this shrimp is found.

Caridina butonensis Klotz & von Rintelen, 2013 is more or less transparent, but has a fine pattern of white and dark stripes. Furthermore, it has reddish pigments all over its body. This shrimp is found in smaller rivers on Buton Island, Indonesia.

All three shrimp species belong to the abbreviated type.

With these newly described species, the number of shrimp species known from Sulawesi Island has increased to 35. The majority of these species belongs to the genus Caridina. 13 of these are riverine species. All in all this is a remarkably high number of diverse species, considering that Sulawesi is not a very large island.
