Redescription. MALE ( Figs 118 View FIGURES 118 – 121 , 126 View FIGURES 122 – 129 ). Body length: 9.8 mm; wing length: 7.2 mm. Head ( Fig. 132 View FIGURES 130 – 137 ). Face slightly protruding antero-ventrally with very weakly demarcated tubercle and strongly concave below antennae. Head 1.7 times wider than face just below the antennae; length of eye contiguity 0.56 times as long as length of frons; angle of eyes at eye contiguity 140o. Face with yellow and black colour pattern; genae, mouth edge and hypostomal bridge black; medial black vitta tridentate with yellow medial area; a large black triangular macula around antennal insertion. Frons yellow. Vertical triangle and dorsal surface of head capsule yellow. Ocellar triangle black. Frontal prominence 0.38 times as long as wide; relative length of pedicel is as 1.5: 1: 1.4. Antennae brown-yellow to black coloured; arista white pilose. Thorax. Scutum black with yellow macula on postpronotum and notopleuron. Pleuron black with two yellow maculae, one each on posterior part of posterior anepisternum and on dorsal part of katepisternum. Pile long and white, ventral half of anterior anepisternum with pile about 2/3 as long as pile on adjacent part of dorsal surface of head capsule. Scutellum yellow with very narrow posterior margin black. Legs. Coxae and trochanter black; pro- and mesofemur predominantly black, only some yellow basally and apically; basal 1/8 and apical 1/10 of metafemur yellow; apico-medial 1/4–1/2 of tibiae black; pro- and mesotarsi darkyellow to dark-brown; metatarsus dark-brown to black. Femora with black setulae apicodorsally; metatrochanter without setulae. Mesofemur with small flattened area antero-basally; metatrochanter relatively narrow with weak sulcus and normal rim laterally. Metafemur elongate and metatibia without appendix on apico-ventral part, elongate, narrow basally and clearly widening medially ( Fig. 152 View FIGURES 151 – 156 ).

Wing. Hyaline except for anterior 1/2 to spurious vein and along vein CuA. Vein R4+5 straight with short appendix into cell r4+5. Cross-vein r-m slightly curved. Membrane covered with microtrichia; alula with anterior margin densely microtrichose, other part bare or with very scattered microtrichia; anterobasal 1/3 of cell cup and a narrow area along anterobasal 1/5 of anal lobe bare; alula relatively narrow, 3.7 times longer than wide. Abdomen. Black and yellow coloured. Length of tergite I: II: III: IV is as 1: 2.7: 2.7: 3.4. Width of yellow fascia medially: length of tergite of respectively tergite II, III and IV as 1: 5.4, 1: 5.4 and 1: 3.8. Tergite II slightly longer than wide, anteromedial part most narrow; length of tergite II: width of tergite II at respectively anterior: narrowest: posterior as 1: 0.74: 0.63: 1.0. Tergite II with triangular maculae on antero-lateral corner, rather widely separated medially, ratio of black between maculae and width of tergite anteriorly 1: 2.0; fascia on tergite II medially broad, narrowed towards lateral margin; fascia on tergite III medially concave and slightly but gradually narrowed towards lateral margin; fascia on tergite IV straight, gradually narrowed towards lateral margin. Tergite IV weakly emarginated. Tergite IV with short bow formed grey-white pollinosity medio-laterally. Sternites I–III posterior with straight yellow fascia. Tergite VIII white pilose.

Genitalia. Epandrium with narrow ventral rim ( Figs 148, 149 View FIGURES 148 – 150 ); in dorsal view, cerci elongate semi-circular shaped ( Fig. 149 View FIGURES 148 – 150 ), pile about as long as width of cerci; surstylus bi-lobed, dorsal lobe rectangular elongate basally broad and with ventro-basal squarish flange, ventral lobe small semi-circular with membranous basal part ( Fig. 148 View FIGURES 148 – 150 ); surstylar apodeme rectangular, separated in two broad elongate sclerotized parts ( Fig. 150 View FIGURES 148 – 150 ); hypandrium ( Fig. 148 View FIGURES 148 – 150 ) very broad, nearly squarish; with short, broad ventral lobe and rugged area basally; superior lobe balloon shaped, articulating with hypandrium; aedeagus with short and broad baso-ventral projection, apex with three projections, dorsally and ventrally short and rounded, medially somewhat longer and rectangular. FEMALE: no description available.

Material examined. Holotype of Ceria euprosopa : 1 Ƌ, " Smyrna / 28-3-[18]63", "Coll. / H. Loew ", " Typus " [faded red label], " Ceria / euprosopa / Lw. " [handwritten], Zool . Mus. / Berlin ", " Holotype Ƌ / Ceria euprosopa / Loew, 1869 / det. J. van Steenis, 2016" [red label] ( ZMHB) . Additional material: 1 Ƌ, 1 ♀ (FSUNS); not studied by the senior author and hence no description of the female is available.
