Ying, Xiaoli & Zhou, Changfa, 2021, The exact status and synonyms of three Chinese Afronurus Lestage, 1924 established by Navás in 1936 (Ephemeroptera: Heptageniidae), Zootaxa 5082 (1), pp. 95-100 : 97-98

Afronurus kiangsuensis ( Puthz, 1971)

Ecdyonurus hyalinus Navás, 1936: 123 , fig. 83 (male, female). Types: male, female, Jiangsu (nec Ecdyurus [sic] hyalinus Ulmer, 1912: 369 , 372; nec Esben-Petersen 1916: 6). Renamed as Ecdyonurus kiangsuensis by Puthz 1971: 44.

Cinygmina rubromaculata You et al., 1981: 28 , pl. 2, figs 14–24 (male, female). Types: male, female, Yixing , Jiangsu province, China. New Synonym .

Cinygmina rubromaculata —Wu et al. 1986: 65, figs 1–11 (nymph).

Cinygmina rubromaculata — Gui 1985: 86; Zhang & Cai 1991: 237; You & Gui 1995: 52, fig. 51 (male); Zhou & Zheng 2003: 758, figs 7, 13, 17 (male and nymph).

Ecdyonurus rubromaculatus — Tshernova et al. 1986: 114.

Cinygmina hainanensis She et al., 1995: 72 , fig. 1 (male, female, male subimago). Types: male, female, subimago, Hainan (Synonymized by Zhou & Zheng 2003: 758).

Afronurus rubromaculatus — Braasch & Jacobus 2011: 65; Zhang et al. 2021: 110 .

Remarks: The abdominal color pattern of this species is very unique ( Fig. 2 ). Comparison of the drawings of Navás ( Fig. 2A ) with specimens of C. rubromaculata ( Figs. 2B, 2C ) shows they are equivalent. The types of them were collected from the same county, Jiangsu province, China. Therefore, we propose the following synonymy: Ecdyonurus kiangsuensis Puthz, 1971 (= Cinygmina rubromaculata You et al., 1981 ).

Ulmer (1912) named a species Ecdyurus hyalinus from the Chinese Taiwan island which was later transferred to the genus Afronurus by Kang & Yang (1994). Ecdyonurus hyalinus Navás, 1936 is therefore a junior homonym and was renamed by Puthz (1971) as Ecdyonurus kiangsuensis . We also redesigned a neotype for this species.

Neotype designation for Afronurus kiangsuensis ( Puthz, 1971) : male imago, China, Jiangsu Province, Yi-Xing County, Hu-Fu Town (31°22′89.41″ N, 119°79′67.42″ E), 18-V-1995, collected by Chaodong Zhu. The neotype designed here was collected from the same province and in a very nearby locality of the original types, and has typical characters mentioned in the original description.

Other material examined: 6 male imagoes, 6 nymphs, same as the neotype; male imago (holotype of Cinygmina rubromaculata You et al., 1981 ), Jiangsu Province, Yi-Xing County, Ming-Lin Town (31°10′5.02″ N, 119°40′17.52″ E), 21-VII-1980, collected by Tian Wu ; 12 male imagoes, 10 female imagoes (paratypes), same data as holotype ; 6 male imagoes, 7 male subimagoes, 10 female imagoes, 8 female subimagoes, 40 nymphs, Hunan Province, Zhang-Jia-Jie City, Jin-Bian creek (29°32′18.93″ N, 110°44′15.57″ E), 12-VIII-2019, collected by Ran Li, Wei Zhang ; 20 male imagoes, 5 male subimagoes, 8 female imagoes, 6 female subimagoes, Hubei Province, Yi- Chang City, Chang-Yang County, Gao-Jia-Yan Town , Qing-Yan Village (30°59′41.08″ N, 111°11′37.93″ E), 20-VII- 2013, collected by Yanxia Wang, Dan Zhou ; 100 nymphs, Hainan Province, Chang-Jiang County, Ba-Wang-Ling (19°06′3761″ N, 109°17′0581″ E), 15-I-2015, collected by Junzhi Sun, Yike Han.
