Ramos-Pastrana leg. (1 ♂, LEUA) (photographed specimen) ; idem Albania, Vda. Vereda] Florida 1, Fca. [Finca] El Jardín, 01º14’50’’N / 75º52’34’’W, 283 m, 01–15.II.2017 (1 ♂, LEUA) ; idem Montañita, Vda. [Vereda] Morros, Fca. [Finca] Las Dalias, 01º29’24’’N / 75º24’09’’W, 348 m, 18.I–01.II.2017 / Trampa Malaise en Bosque (Suelo) (1 ♂, LEUA) .

Distribution. Colombia (Caquetá) (New record), Costa Rica (Guanacaste) ( Fig. 7 ).

Remarks. We have examined three specimens of this species and all differs from the male holotype of S. maculipennis by the brown palpus (yellow in S. maculipennis ), It 3 white (dark in S. maculipennis ) and posterior membrane of wing apparently mostly reduced, forming a more conspicuous petiole than in S. maculipennis (see Bickel 2015, fig. 1e). However, the male terminalia ( Fig. 5F ) is virtually identical and we have chosen to keep these specimens identified as S. maculipennis .
