Syneches bilobatus Menezes & Ale-Rocha  

( Figs 12A–E View FIGURE 12 , 50 View FIGURE 50 )

Syneches bilobatus Menezes & Ale-Rocha, 2016: 411–413   View Cited Treatment , figs 26–32, 106, 118. Type locality: Manaus , Amazonas, Brazil.

Diagnosis. Small size (1.8 mm) ( Fig. 12A View FIGURE 12 ). Antenna dark brown ( Fig. 12C View FIGURE 12 ). Scutum pyramidal-shaped, broader than mesopleuron in lateral view, covered with reddish brown pruinescence ( Fig. 12B View FIGURE 12 ). Fore and mid tibiae brown to dark brown with yellow base and apex; hind tarsomere 1 brown with base and apex yellow. Wing hyaline; pterostigma inconspicuous; R 2+3 slightly angulate apically; cells br, bm and cua subequally long; second section of M 1 slightly shorter than crossvein r-m ( Fig. 12E View FIGURE 12 ). Apical margin of hypandrium slightly convex and epandrial lamellae with short apical projection.

Type material examined. HOLOTYPE ♂ ( INPA) labelled: “ BRASIL, Amazona s, Manaus, R[eserva Florestal Adolpho ] Ducke , 16–17.iii.1993, Varredura-orla da mata, João Vidal ” “ Holótipo, Syneches bilobatus, Menezes & Ale-Rocha   ” [red label]   . Holotype condition: left hind leg and right mid tarsus broken off; not dissected.

Distribution. Brazil (Amazonas) ( Fig. 50 View FIGURE 50 ). Syneches bilobatus   is known to occurr only from the Amazon biome.

Remarks. Syneches bilobatus   is similar to S. pyramidatus   given the wing hyaline, pterostigma inconspicuous, scutum pyramidal-shaped, broader than mesopleuron and covered with reddish brown pruinescence. However, the species differs from S. pyramidatus   by the brown to dark brown fore and mid tibiae with yellow base and apex (yellow in S. pyramidatus   ), hind tarsomere 1 brown with base and apex yellow (yellow in S. pyramidatus   ) and second section of M 1 slightly shorter than crossvein r-m (second section of M 1 longer than r-m in S. pyramidatus   ). The original description states that there is yellowish-gray pruinescence forming dorsocentral and supra-alar stripes ( Menezes & Ale-Rocha 2016), but we could not distinguish the yellowish-gray stripe in the holotype and paratypes, and now consider that the whole scutum is covered with a reddish brown pruinescence.
