Syneches pyramidatus Bezzi  

( Figs 36A–E View FIGURE 36 , 58 View FIGURE 58 )

Syneches pyramidatus Bezzi, 1905: 428   ; 1909: 314 (key); Collin, 1933: 128 (cit.); Smith, 1962: 213, fig. 14 ( Brazil); 1967: 10 (cat.); Rafael & Ale-Rocha, 1995: 543, figs 50–51, 67 (rev.); Yang et al., 2007: 311 (cat.); Ale-Rocha & Vieira, 2008: 120 (cit.); Menezes & Ale-Rocha, 2016: 427 View Cited Treatment , fig. 122 (distr.). Type-locality: Chanchamayo, Peru.

Diagnosis. Small size (2.7 mm). Antenna dark brown, postpedicel as long as preceding segments combined ( Fig. 36C View FIGURE 36 ). Scutum pyramidal-shaped, covered with reddish brown pruinescence ( Figs 36A, B View FIGURE 36 ), broader than mesopleuron in lateral view. Legs with femora brown to dark brown, fore and mid femora yellow at apex; hind tibia usually with darker ring at mid-length and all tarsomeres 5 darker, otherwise yellow ( Figs 36A, D View FIGURE 36 ). Wing hyaline, pterostigma inconspicuous; second section of M 1 longer than crossvein r-m ( Fig. 36E View FIGURE 36 ).

Material examined. BRAZIL. Amazonas: Manaus, RFAD [Reserva Florestal Adolpho Ducke], 18.vi.1996, J.C.H. Guerrero, Fogging in Pouteria glomerata   ( Sapotaceae   ) (1 ♂, INPA); idem, 01.vi.1996, Corythophora alta   ( Lecythidaceae   ), (1 ♀, INPA); idem, 21.vii.1995, Eschweilera wachenheimii (Lecyth)   (1 ♀, INPA); idem, 26.vii.1995, Eschweilera pseudodecolarans   (1 ♀, INPA).

Distribution. Brazil (Amazonas and Santa Catarina) ( Fig. 58 View FIGURE 58 ); and Peru.

Remarks. Syneches pyramidatus   is similar to S. bilobatus   by the scutum pyramidal-shaped and the wing hyaline with pterostigma inconspicuous. However, it differs by the tibiae and hind tarsomere 1 mostly yellow (mostly brown in S. bilobatus   ) and the second section of M 1 longer than crossvein r-m (slightly shorter than r-m in S. bilobatus   ).
