Remarks
Among the six valid Chinese Afronurus species , A. yixingensis and A. hunanensis are separated into one group because of the similar color patterns of the head capsule in nymphs. However, as stated above for A. hunanensis , the nymphs can be separated by shape of hypopharynx, glossae, gills VII, number of comb-shaped setae on maxillae and color patterns of caudal filaments. In the male imago, they can easily be differentiated by shape of penes, titillators and projection between penial lobes.
Distribution
China (Hebei, Hubei, Hunan, Anhui, Jiangxi, Guizhou, Jiangsu, Zhejiang, Fujian, Hainan).
Ecology
Among the six Chinese Afronurus species studied in this paper, A. obliquistriatus , A. rubromaculatus and A. yixingensis are more common than the others and they are frequently found at the collecting sites. The last instar nymphs of A. obliquistriatus are recorded molting at about 10:00–12:30 AM or 17:00–19:30 PM while the last instar nymphs of A. rubromaculatus and A. yixingensis molted at about 16:00–19:00 PM local time, and these three species are observed molting underwater. The subimagoes persisted for 1–2 days and molted at 12:00–15:00 PM, the whole process lasting about 2–4 minutes. Moreover, in another observed species, A. drepanophyllus sp. nov., the last instar nymph molted at about 17:00–18:00 PM and the male subimago molted at 15:00–16:00 PM, the process lasting about 90 seconds.
