Syneches repletus Bezzi, 1909: 317 View in CoL ; Collin, 1933: 28 (citation); Smith, 1967: 10 (catalog); Rafael & Ale-Rocha, 1995: 540 (review); Yang et al., 2007: 309 (catalog); Ale-Rocha & Vieira, 2008: 120 (record).

Syneches hyspidus Ale-Rocha & Vieira, 2008: 115 . syn. nov.

Diagnosis. Medium size (about 3.5 mm length) and dark brown. Ocellar triangle flat; antenna black. Scutum high and rounded, dark brown to black, with grey pruinescence on sides and prescutellar disc; prosternum narrow; scutellum brown with grey pruinescence and five pairs of marginal setae. Abdomen brown with long and waved setae. Legs yellow, except coxa, trochanter, distal 1/2 of femur and hind tibia brown; fore femur and tibia and hind tarsomere 1 swollen; mid tibia with 1 AD subbasal, 1 P and 1 very long V apical seta. Wing hyaline, pterostigma brown, large, filling out the apex of cell r1. Phallus long, same length as postgonite, slender at the distal half with two lateral protuberances.

Variations. The yellow portion of hind femur varies from 1/2 to 1/3 or less; rounded pterostigma not completely filling the apex of cell r1; phallus longer than usual, longer than the postgonite, with elongation after the second pair of lateral protuberances, reaching the apex of epandrial lamella.

Geographical distribution. Brazil (Amazonas, Pará*, Acre*), Peru and Venezuela * ( Fig. 122 View FIGURE 122 ).

Comments. Species similar to S. manaos , as mentioned before, but differs from it by the vein R2+3 slightly bent to Costa, hind femur completely brown and features of male terminalia.

Until now the male of S. repletus was unknown. Ale-Rocha & Vieira (2008) described S. hispidus based on males and females. The examination of female specimens of S. repletus and female specimens of the type series of S. hispidus revealed that they were very similar, lacking significant characters to distinguish them. Therefore, the synonymy is being established, and consequently the male of S. repletus is considered as described under S. hispidus in Ale-Rocha & Vieira (2008).
