Heptageniidae (Insecta, Ephemeroptera) of Thailand Author Boonsoong, Boonsatien Author Braasch, Dietrich text ZooKeys 2013 272 61 93 http://dx.doi.org/10.3897/zookeys.272.3638 journal article http://dx.doi.org/10.3897/zookeys.272.3638 1313-2970-272-61 Genus Afronurus Lestage, 1924 Figs 3A4 D-G8C-D 9A Remarks. The synonymization of Cinygmina with Afronurus is recognized by Wang and McCafferty (2004) , Kluge (2004) , and Braasch and Freitag (2008) . The genus Afronurus includes at least 43 species from the Oriental region ( Braasch 1987 , 1990 , 2005 , 2011 ; Braasch and Boonsoong 2010 , Braasch and Soldan 1984a , 1987 , Flowers and Pescador 1984 , Braasch and Jacobus 2011 , Kang and Yang 1994 , Kimmins 1937 , Nguyen and Bae 2003 , Venkataraman and Sivaramakrishnan 1989 , Zhou and Zheng 2003 ). It indicates the complicated situation in determining species of Afronurus in the Oriental; in Southeast Asia many species are known only by larvae, or described as adults with affiliation of larvae from the same locality; the rearing of species and genetic investigations will be the aim of a future research. Afronurus larvae are usually the dominant heptageniid benthic macro-invertebrates in Thai streams. In this study, we propose five described species of the genus Cinygmina Kimmins, 1937 = Afronurus Lestage, 1924.
