( Figs. 21G View FIGURE 21 , 27C View FIGURE 27 , 30P View FIGURE 30 , 39B View FIGURE 39 , 45N View FIGURE 45 , 52A View FIGURE 52 , 66C View FIGURE 66 , 76F View FIGURE 76 )

DIAGNOSIS: Only pupa of Ceratopogonidae with the metathorax with only one campaniform sensillum (M-3-T) situated at least ⅓ the length of the metathorax from its anterior margin ( Fig. 52A View FIGURE 52 ), abdominal segment 1 with D-2- I and D-3-I well separated ( Fig. 52A View FIGURE 52 ), and abdominal segment 4 with L-1-IV a long seta ( Fig. 66C View FIGURE 66 ).

DESCRIPTION: Total length = 3.81 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 extending into eye sheath (as in Figs. 17A View FIGURE 17 , 79I View FIGURE 79 ). Head: Dorsal apotome ( Fig. 21G View FIGURE 21 ), without 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. 27C View FIGURE 27 ) with mandible well-developed, lacinia absent; palpus extending posterior to posterolateral margin of labium; labium separated medially by labrum, hypopharynx; apex of antenna ( Fig. 39B View FIGURE 39 ) barely anterior to equal to posterior extent of midlength portion of midleg (portion lateral to mesosternum), narrowed posteriorly; sensilla: dorsal apotomals ( Fig. 21G View FIGURE 21 )—1 elongate seta, 1 campaniform sensillum; dorsolateral cephalic sclerite sensilla—1 seta, 1 campaniform sensillum; clypeal-labrals ( Fig. 27C View FIGURE 27 )—2 thick setae; oculars ( Fig. 27C View FIGURE 27 )—2 setae, 1 campaniform sensillum. Thorax: Prothoracic extension ( Fig. 27C View FIGURE 27 ) wide, well-developed, extending from palpus to antenna; mesonotum with short tubercles, not extending posteromedially, not dividing metathorax medially ( Fig. 52A View FIGURE 52 ); respiratory organ ( Fig. 45N View FIGURE 45 ) length/width = 3.50, very short, squat, somewhat flattened apically, with pores closely abutting at apex of respiratory organ, arranged in single curved row, outer surface smooth, with short, wide pedicel, base with short posteromedial apodeme, membranous base of respiratory organ short, tracheal tube straight to slightly curved along length, with spirals restricted to base, wrinkles to 1/3 length; wing ( Fig. 39B View FIGURE 39 ) without apical tubercle or angle, separated medially by fore-, midlegs; halter apex and hind leg (as in Fig. 33A View FIGURE 33 ) broadly abutting; halter apex abutting anterolateral knoblike extension of tergite 2; legs ( Fig. 39B View FIGURE 39 ) with lateral margin of foreleg near midlength of wing evenly curved; hind leg visible at lateral margin of wing (as in Fig. 33E 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 short peg, 1 elongate seta, 1 campaniform sensillum (as in Fig. 31N View FIGURE 31 ); anterolaterals—1 moderately long seta; dorsal setae ( Fig. 30P View FIGURE 30 )—D-1-T, D-2-T, D-5-T peg-like setae, D-4-T seta, D-3-T campaniform sensillum; D-1-T, D-2-T on single, short tubercle, D- 3-T lateral to D-4-T; supraalar 2—campaniform sensillum; metathoracics ( Fig. 52A View FIGURE 52 )—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, 2 pairs on tergite 8, at least sternites 3–5 with medial stripe, anterolateral spot (sternites 6–7 membranous), segment 2 as wide or slightly wider than segment 3, segments with undivided, peg-like or thin to thick setae, with rounded to pointed, short to moderately elongate tubercles, with sternites 6–7 each with membranous disc; segment 9 ( Fig. 76F View FIGURE 76 ) not strongly modified, terminal processes closely approximated basally, each projecting posterodorsolaterally, tapering to pointed apex; sensilla: tergite 1 ( Fig. 52A View FIGURE 52 ) with 8 setae, 2 campaniform sensilla, including 3 lateral sensilla, D-2- I, D-3-I well separated, D-7-I situated anteriorly near D-3-I; segment 4 ( Fig. 66C View FIGURE 66 )—D-2-IV, D-3-IV short to moderately elongate setae on short tubercles; D-5-IV, D-8-IV peg-like setae, D-9-IV moderately elongate seta; 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 elongate seta on pointed tubercle, well anterior of posterior lateral setae; L-2-IV, L-4-IV short setae, L-3-IV elongate seta on pointed tubercles, V-5-IV, V-7-IV short setae, V-6-IV elongate seta, on short or moderately elongate tubercles, all closely approximated; segment 8 without D-3-VIII, without L-1-VIII; segment 9 ( Fig. 76F View FIGURE 76 )—with D-5-IX, D-6-IX campaniform sensilla.

DISTRIBUTION AND HABITAT: The genus Neobezzia is known from eight species in the Neotropical Region ( Borkent 2014 ). Immatures were found in mats of the floating aquatic fern Salvinia auriculata in a lagoon or among plants and algal mats in a pond.

TAXONOMIC DISCUSSION: Only two species of Neobezzia are known as pupae ( Tables 2–3 View TABLE 2 View TABLE 3 ). Ronderos et al. (2011) provided detailed SEM photomicrographs as well as description of N. fittkau . They reported the total length of male pupae as 4.06–4.64 mm and that of females as 4.86–4.98 mm but included the length of the terminal process (not included here). Regardless, this genus shows the sexual dimorphism in size present in all Heteromyiini + Sphaeromiini s. lat. + Palpomyiini + Stenoxenini and some genera of Ceratopogonini .
