Syneches tenebricus Menezes & Ale-Rocha  

( Figs 44A–E View FIGURE 44 , 54 View FIGURE 54 )

Syneches tenebricus Menezes & Ale-Rocha, 2016: 431–432   View Cited Treatment , figs 87–91, 114, 123. Type locality: Manaus , Amazonas, Brazil.

Diagnosis. Medium size (3.5 mm) ( Fig. 44A View FIGURE 44 ). Antenna yellow ( Fig. 44C View FIGURE 44 ). Scutum rounded, as broad as mesopleuron in lateral view, dark brown, covered with reddish brown pruinescence ( Fig. 44B View FIGURE 44 ). Foreleg from coxa to basal 2/3 of femur brown and apex of hind femur with a small brown spot, otherwise yellow ( Figs 44A, D View FIGURE 44 ). Wing brown; pterostigma oval, dark brown, extended from apex of R 1, ending near to the apex of cell r 1; second section of M 1 slightly longer than crossvein r-m; cell bm longer than cells br and cua ( Fig. 44E View FIGURE 44 ).

Type examined material. HOLOTYPE ♂ ( INPA) labelled: “ BRASIL, Amazonas , Manaus, F [Fazenda] Esteio, BR-174, KM 41” “ 17–20.xii.1993, F.F. Xavier ” “Holótipo, Syneches tenebricus Menezes & Ale-Rocha     . Holotype condition: left wing damaged, hind left leg broken off; not dissected.

Additional examined material. Same data as holotype (1 ♂, INPA)   .

Distribution. Brazil (Amazonas and Roraima) ( Fig. 54 View FIGURE 54 ). The species is recorded only from two very contrasting landscapes in the Amazon biome, namely from Manaus (central Amazon, State of Amazonas) and Pacaraima (northern Amazon, state of Roraima). However, it is interesting to note that both localities are composed of essentially different vegetation types; while the landscape nearby Manaus is predominantly of close canopy rainforest, Pacaraima shows a predominantly open savanna-like landscape.

Remarks. Syneches tenebricus   is similar to S. fuscus   sp. nov., differing from it due to the antenna and femora being predominantly yellow (except fore femur mostly brown), while in S. fuscus   sp. nov. the antenna is dark brown and the fore and mid femora have more extensive brown markings (see also “Remarks” under S. fuscus   sp. nov.).
