Streptocephalus diversity in Myanmar, with description of a new species
Streptocephalus sirindhornae Sanoamuang et al., 2000 is reported in Myanmar for the first time, and Streptocephalus shinsawbuae sp. n. is described as new.
The diversity of anostracans in Myanmar is poorly known. The Southeast Asia Biodiversity Research Institute (Chinese Academy of Sciences) and the Forest Research Institute, Myanmar, conducted a series of biodiversity surveys in Myanmar from 2015 to 2017. Two Streptocephalus species were collected during these efforts: the first records of S. sirindhornae Sanoamuang et al., 2000 from Myan?mar and a species new to science.
Streptocephalus shinsawbuae sp. n. belongs to the S. dichotomus group and is similar to S. simplex Bond, 1934 and S. sahyadriensis Rogers & Padhye, 2014, but can be distinguished by the form of the male antennal posterior primary ramus and anterior primary ramus apex and egg ornamentation. Streptocephalus dichotomus has been reported from Myanmar in the past but was not found in this survey.
This study was supported by the Southeast Asia Biodiversity Research Institute, the Chinese Academy of Sciences (Y4ZK111B01), the National Natural Science Foundation of China (31702011) and the Yunnan Provincial Science and Technology Program (2014FB178). The result published as " Streptocephalus diversity in Myanmar, with description of a new species (Branchiopoda, Anostraca)" on ZooKeys.
