Hsi-Te
Shih and Yixiong Cai (2007) Two new species of land-locked
shrimp, Neocaridina saccam
and N. ketagalan (Decapoda:
Caridea: Atyidae), are described from Tainan, southwestern Taiwan, and
Taipei, northern Taiwan, respectively. Based on morphological and
molecular (mitochondrial 16S rRNA and cytochrome oxidase I genes)
evidence, both can be distinguished from their congeners. A speciation
model for this genus on the island of Taiwan is also proposed based on
geological events and molecular clock estimates.
Key words: Neocaridina
saccam, N. ketagalan,
16S rRNA, Cytochrome oxidase I, Biogeography.
