DESCRIPTION : Total length = 3.20–3.80 mm . Without larval exuviae retained on abdomen. Exuviae with flagellum appressed against lateral margin of midleg, wing (as in Figs. 16B , 33B ). Ecdysial tear around base of antenna, along lateral margin of face to palpus (as in Figs. 17C , 79H ). Head : Dorsal apotome ( Fig. 22F ), uncertain ventral line of weakness, without dorsomedial tubercle, without central dome; dorsolateral cephalic sclerite (as in Fig. 13H ) fused to scutum, each side separated medially by dorsal apotome in whole pupa; mouthparts ( Fig. 28E ) with mandible well-developed, lacinia absent; palpus extending posterior to posterolateral margin of labium; labium entire (not divided medially); apex of antenna ( Fig. 41B ) anterior to posterior extent of midlength portion of midleg (portion lateral to mesosternum), narrowed posteriorly; sensilla: dorsal apotomals ( Fig. 22F )—1 elongate seta, 1 campaniform sensillum; dorsolateral cephalic sclerite sensilla—1 seta, 1 campaniform sensillum on very short tubercle; clypeal-labrals ( Fig. 28E )—2 slender setae; oculars ( Fig. 28E )—2 setae, 1 campaniform sensillum. Thorax : Prothoracic extension ( Fig. 28E ) wide, well-developed but very narrow dorsolaterally, extending from palpus to antenna; mesonotum without tubercles, not extending posteromedially, not dividing metathorax medially ( Fig. 53E ); respiratory organ ( Fig. 46L ) length/width = 3.13–4.08, elongate, moderately slender, somewhat flattened apically, with pores closely abutting at apex of respiratory organ, arranged in single row, outer surface with some wrinkles, with short, wide pedicel, base with moderate elongate posteromedial apodeme, membranous base of respiratory organ short, annulated, tracheal tube straight to slightly curved along length, with spirals restricted to base, wrinkles to half length; wing ( Fig. 41B ) with short tubercle at apex of hind leg, separated medially by fore-, midlegs; halter apex and hind leg (as in Fig. 33J ) broadly abutting; halter apex extending posteriorly to 1/6 length of tergite 2; legs ( Fig. 41B ) with lateral margin of foreleg near midlength of wing evenly curved; hind leg visible at lateral margin of wing (as in Fig. 33J ); with apex of foreleg moderately anterior to apex of midleg; apex of hind leg abutting apex of midleg laterally; sensilla: anteromedials—1 long, 1 medium setae, 1 campaniform sensillum; anterolaterals—1 moderately long seta; dorsal setae ( Fig. 31F )—D-1-T, D-2-T, D-4-T, D- 5-T setae, D-3-T campaniform sensillum, D-3-T anterior to D-4-T; supraalar 2—campaniform sensillum; metathoracics ( Fig. 53E )—1 campaniform sensillum; M-3-T distant from margin of metathorax (at least 1/3 length of metathorax). Abdomen : pigmentation light brown, with tergite 1 with 3 medial spots, tergites 2-7 with medial area with stripe, 2 anterolateral spots, sternites 3-7 with medial stripe, anterolateral spot (light brown), segment 2 as wide or slightly wider than segment 3, segments with undivided, peg-like or thin to thick setae, with rounded, short to moderately elongate tubercles, tergites or sternites entire, each without membranous disc; segment 9 ( Fig. 77 I-J) not strongly modified, terminal processes separated basally, each projecting posterodorsolaterally, tapering to pointed apex; sensilla: tergite 1 ( Fig. 53E ) with 7 setae, 2 campaniform sensilla, including 3 lateral sensilla, D-2-I, D-3-I closely approximated, D-7-I situated anteriorly near D-3-I; segment 4 ( Fig. 70A )—D-2-IV, D-3-IV short to moderately elongate setae on short tubercles; D-5-IV peg-like seta, D-8-IV, D-9-IV short to moderately elongate setae; D-5-IV on single tubercle, D-8-IV, D-9-IV on separate but closely approximated tubercles, posterior dorsal sensilla in transverse row, arranged medially to laterally: D-5-IV, D-4-IV, D-8-IV, D-9-IV; D-7-IV near D-3-IV; L- 1-IV short seta on rounded tubercle, well anterior of posterior lateral setae; L-2-IV, L-4-IV short setae, L-3-IV moderately elongate seta on rounded tubercles, V-5-IV, V-6-IV short setae, V-7-IV moderately elongate, on moderately elongate tubercles, V-5-IV, V-6-IV moderately closely approximated; segment 8 without D-3-VIII, without L-1-VIII; segment 9 ( Fig. 77I–J )—with D-5-IX, D-6-IX campaniform sensilla. DISTRIBUTION AND HABITAT : The genus Clastrieromyia is known from four species in the Neotropical Region ( Borkent 2014 ). Immatures of the only known species have been collected from a cattle-trodden bog. TAXONOMIC DISCUSSION : Only one species is known as a pupa ( Tables 2–3 ). MATERIAL EXAMINED : C. dycei : 2 pupal exuviae (of paratypes ), Tacuarembo , Uruguay , 29-IX-1980 ( MLPA ) .
