Syneches vidali Ale-Rocha & Vieira  

( Figs 47A–E View FIGURE 47 , 55 View FIGURE 55 )

Syneches vidali Ale-Rocha & Vieira, 2008: 120   , figs 29–35, 40; Menezes & Ale-Rocha, 2016: 433 View Cited Treatment , fig. 123 (key, distr.). Type locality: Parque Nacional do Jaú, Amazonas, Brazil.

Diagnosis. Small size (2.6 mm) ( Fig. 47A View FIGURE 47 ). Antenna with scape and pedicel brown, postpedicel brown on basal half and pale yellow on apical half ( Fig. 47C View FIGURE 47 ), sometimes varying from entirely brown to entirely yellow. Scutum broader than mesopleuron in lateral view, dark brown covered with reddish brown pruinescence, except by pprn lb, dc stripe and prescutellar disc covered both with gray pruinescence; one circle of gray pruinescence on npl and other just above npl ( Fig. 47B View FIGURE 47 ). Wing sub-hyaline, pale brown, pterostigma divided into two brown spots, one triangular, posterior to apex of R 1, and one quadrangular extended beyond the apex of cell r 1; second section of M 1 slightly longer than crossvein r-m ( Fig. 47E View FIGURE 47 ).

Type material examined. HOLOTYPE ♂ ( INPA) labelled: “ BRASIL, Amazonas , Parque Nacional [do] Jaú, 29.vii–08.viii.2001, 01°54′46″S 61°35′23″W; Arm[adilha] Malaise, campina arbustiva, Henriques & Vidal” “Holótipo, Syneches vidali Ale-Rocha & Vieira   [red label]” GoogleMaps   . Holotype condition: good; not dissected.

Additional material examined. BRAZIL. Maranhão: Bom Jardim, REBIO-Res. Biol. Gurupi, Armad. Luminosa Móvel , 17–27.i.2010, F. Limeira-de-Oliveira, J.T. Câmara & M.B. Aguiar Neto, cols. (3♀, CZMA)   . Rio Grande do Norte: Baía Formosa, Mata Estrela , 06°23′19″S 35°01′05″W, 44 m, 24.v.2007, J.A. Rafael & F.F. Xavier F., Luz (2 ♂, INPA) GoogleMaps   . Minas Gerais: Ouro Preto , 12–13.iv.1968, F.C. Val, col. (4 ♂, 1 ♀, MZUSP)   . São Paulo: Cássia dos Coqueiros, Mun. Cajuru , ix.1954, M.P. Barretto col. (3 ♂, MZUSP)   ; Praia de Guaratuba, Bertioga , 1969, F.C. Val, col. (1 ♂, MZUSP)   .

Distribution. Brazil (Amazonas, Maranhão *, Minas Gerais *, Rio Grande do Norte *, São Paulo *) ( Fig. 55 View FIGURE 55 ). Syneches vidali   was originally described from the Amazon biome and it is now recorded occurring also in the Atlantic Forest biome.

Remarks. Syneches vidali   is similar to S. maculosum   as mentioned above (see “Remarks” under S. maculosum   ). However, S. vidali   can be differentiated by the pruinescence pattern on the scutum and the pterostigma extends beyond the apex of cell r 1.
