Etymology. – From the Latin word productus in reference to the dorsal part of the epandrium that is considerably produced posteriorly. Diagnosis. – Medium-sized blackish species with all bristles black, fore tibia deformed with row of anterodorsal spinelike bristles on basal third, first fore tarsomere elongated, following three tarsomeres swollen with numerous long, fine dorsal bristles, wing with visible veins, epandrium produced posterodorsally. Description. – Male – Head . Occiput dark brown blackish, antenna black, first flagellomere somewhat conical, second Fig. 2. Male hypopygium of E. ( C. ) neesoonensis , lateral view. Scale = 4.2 mm. and third flagellomeres aristiform. Palpus brown, labrum length 1.5x head height. Thorax blackish. Dorsocentrals uniserial ending with 2 strong, long bristles in prescutellar depression. Legs ( Fig. 1B ). Fore tibia deformed with row of anterodorsal spine-like bristles on basal third ending in 2-4 longer bristles (well visible in anterior view); first fore tarsomere elongated, almost as long as the following four tarsomeres together, with 1 distinct anterolateral and posterodorsal bristles at base and at tip respectively; following three tarsomeres swollen with numerous long rather fine dorsal bristles, 1 strong, long ventral bristle. Mid tibia with 3 strong, long ventral and dorsal bristles; first mid tarsomere with 1 strong, long posterodorsal bristle at base and at tip. Hind tibia and tarsus with several strong, long postero- and anterodorsal bristles, hind tarsus somewhat thick. Wing (length = 2.4 mm ) feebly tinged with brown, all veins well visible except M1, A1 abbreviated. Halter dark brown. Abdomen dark brown, paler, with distinct short bristles at base. Hypopygium ( Fig. 4 ). Epandrium rather truncate at tip, projected posterodorsally, with row of very strong, long bristles on the dorsal margin, several shorter, finer bristles at tip. Hypandrium somewhat rounded at tip. Phallus rather long, narrowed at tip. Female unknown. Remarks. – This species belongs to the E. jacobsoni clade as defined recently (Daugeron & Grootaert, 2005). Within this clade it is closely related to E. padangensis ( Indonesia : Sumatra ) with fore tarsus distinctly less rounded than in this species. Both species occur in the same kind of coastal habitat, i.e. in mangroves ( Fig. 5 ).
