( Figs. 22F View FIGURE 22 , 28E View FIGURE 28 , 31F View FIGURE 31 , 41B View FIGURE 41 , 46L View FIGURE 46 , 53E View FIGURE 53 , 70A View FIGURE 70 , 77I–J View FIGURE 77 )

DIAGNOSIS: Only pupa of Ceratopogonidae with the metathorax with a single campaniform sensillum (M-3-T) situated at least ⅓ the length of the metathorax from its anterior margin ( Fig. 53E View FIGURE 53 ), apex of the halter extending posteriorly to about 1/6 length of tergite 2 (as in Fig. 33L View FIGURE 33 ), D-7-I near D-3-I ( Fig. 53E View FIGURE 53 ), abdominal segment 4 with each setae on a rounded tubercle ( Fig. 70A View FIGURE 70 ) and abdominal segment 8 without L-1-VIII.

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 View FIGURE 16 , 33B View FIGURE 33 ). Ecdysial tear around base of antenna, along lateral margin of face to palpus (as in Figs. 17C View FIGURE 17 , 79H View FIGURE 79 ). Head: Dorsal apotome ( Fig. 22F View FIGURE 22 ), uncertain ventral line of weakness, without dorsomedial tubercle, without central dome; dorsolateral cephalic sclerite (as in Fig. 13H View FIGURE 13 ) fused to scutum, each side separated medially by dorsal apotome in whole pupa; mouthparts ( Fig. 28E View FIGURE 28 ) with mandible well-developed, lacinia absent; palpus extending posterior to posterolateral margin of labium; labium entire (not divided medially); apex of antenna ( Fig. 41B View FIGURE 41 ) anterior to posterior extent of midlength portion of midleg (portion lateral to mesosternum), narrowed posteriorly; sensilla: dorsal apotomals ( Fig. 22F View FIGURE 22 )—1 elongate seta, 1 campaniform sensillum; dorsolateral cephalic sclerite sensilla—1 seta, 1 campaniform sensillum on very short tubercle; clypeal-labrals ( Fig. 28E View FIGURE 28 )—2 slender setae; oculars ( Fig. 28E View FIGURE 28 )—2 setae, 1 campaniform sensillum. Thorax: Prothoracic extension ( Fig. 28E View FIGURE 28 ) wide, well-developed but very narrow dorsolaterally, extending from palpus to antenna; mesonotum without tubercles, not extending posteromedially, not dividing metathorax medially ( Fig. 53E View FIGURE 53 ); respiratory organ ( Fig. 46L View FIGURE 46 ) 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 View FIGURE 41 ) with short tubercle at apex of hind leg, separated medially by fore-, midlegs; halter apex and hind leg (as in Fig. 33J View FIGURE 33 ) broadly abutting; halter apex extending posteriorly to 1/6 length of tergite 2; legs ( Fig. 41B View FIGURE 41 ) with lateral margin of foreleg near midlength of wing evenly curved; hind leg visible at lateral margin of wing (as in Fig. 33J View FIGURE 33 ); 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 View FIGURE 31 )—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 View FIGURE 53 )—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 View FIGURE 77 I-J) not strongly modified, terminal processes separated basally, each projecting posterodorsolaterally, tapering to pointed apex; sensilla: tergite 1 ( Fig. 53E View FIGURE 53 ) 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 View FIGURE 70 )—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 View FIGURE 77 )—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 View TABLE 2 View TABLE 3 ).

MATERIAL EXAMINED: C. dycei : 2 pupal exuviae (of paratypes), Tacuarembo, Uruguay, 29-IX-1980 ( MLPA) .
