Types : male, female, Kuling , Jiangxi province , China . Ecdyonurus pallescens — Gui 1985: 87 . Cinygmina obliquistriata You et al. , 1981: 26 , pl. 1, figs 1–13 (male, female). Types : male, female, Yixing , Jiangsu Prov. New Synonym . Cinygmina obliquistriata —Wu et al. 1986: 65, figs 12–22 (nymph). Cinygmina obliquistriata — Gui 1985: 86 ; Zhang & Cai 1991: 237 ; You & Gui 1995: 51 , fig. 50 (male); Su et al. 1995: 41 ; Gui et al. 1999: 330 , figs 11-10 (male); Zhou & Zheng 2003: 756 , figs 9, 12, 16 (male and nymph). Afronurus obliquistriatus — Braasch & Jacobus 2011: 65 ; Zhang et al. 2021: 109 . Remarks : Both imagoes ( Figs. 1B, 1C ) and nymphs of C. obliquistriata have remarkable oblique abdominal stripes that clearly match the original descriptions and drawings ( Fig. 1A ) of E. pallescens by Navás (1936) . Therefore, we propose the following synonymy: Ecdyonurus pallescens Navás, 1936 (= Cinygmina obliquistriata You et al. , 1981 ). In addition, since the types of this species are lost (Alba–Tercedor & Peters 1985), we redesign a neotype for it. FIGURE 1. Abdomen of Afronurus pallescens ( Navás, 1936 ) male imago.
