Syneches hyspidus Ale-Rocha & Vieira, 2008: 115 ; Menezes & Ale-Rocha, 2016: 428 (syn.).

Legs with coxae, trochanters, apical half to apical 2/3 of hind femur and apical half of hind tibia brown, otherwise yellow ( Figs 38A, C, D ); mid tibia with 2 bristles about as long as mid tibia (1AD on basal third, 1AV on basal half); hind femur strongly swollen with 1AV row of spiniform bristle inserted on prominent tubercles ( Fig. 38C ), slightly swollen on females ( Fig. 38D ). Wing hyaline, pterostigma brown, wide, filling or ending near apex of cell r 1; R 2+3 slightly angulate apically; second section of M 1 slightly longer than crossvein r-m ( Fig. 38E ).

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. (2 ♂, 1 ♀, CZMA) . Amazonas: Manaus, Res. Km 41, PDBFF, 23–24.vi.2004 Sub-bosque, R. Querino (1♂, 1♀, INPA) ; ZF-2, km 14 Torre , 02°35′21″S 60°06′55″W, 19.vi.2015, J.M. Cumming, S. Cumming, D.W.A. Marques & J.A.

Distribution. Brazil (Acre, Amazonas, Pará and Maranhão *) ( Fig. 52 ); Colombia *, Peru and Venezuela. Syneches repletus is recorded only from the Amazon biome.

Remarks. Syneches repletus is similar to S. manaos , the former differing mainly by R 2+3 only slightly angulate apically and characters of male terminalia (see also “Remarks” under S. manaos ).
