Muscat , Haramel; HT ♂, NMWC]. Distribution. Afrotropical : Oman , United Arab Emirates . Additional material examined. United Arab Emirates : Khor Fakkan, 25°22.1’N56°20.9’E , beach, 11.iii.2010 , W.N. Mathis, 8 ♂♂ 5 ♀♀; Sharm, 25°28.9’N56°21.7’E , beach, 17.iii.2010 , W.N. Mathis, 2 ♂♂, [LMC, USNM]. Remarks. Nocticanace affinis is closely related to N. sinensis Delfinado, 1971 , because of the similar shape of the surstylus, as well as for having the same chaetotactic pattern on the posterior margin, that is, with a few thick setae intermixed with long, slender setae (figs. 1‒3). However, the surstylus of N. affinis is characterised by a peculiar shape that does not match the figures given by Delfinado (1971) and Mathis (1982). Indeed, it shows a strongly sinuous surstylus, with a long, tapered, claw-shaped apex in lateral view. Furthermore, slight but consistent differences are also found in the shape and chaetotaxy (stout setae) of the female sternites 7–8.
