Cordulecerus surinamensis ( Fabricius, 1798) ( Figs. 9 , 10 )

Ascalaphus surinamensis Fabricius, 1798: 207 . Holotype, sex unknown. Type locality: Suriname (Type depository unknown).

Specimens examined: Colombia: Amazonas: Leticia, Ruta de Tarapaca, km 11, Reserva Tanimboca , 19-25-IX.2015 90 m, lat. – 04.1197, long. – 69.9523, C. Gonzalez, ligth trap (1 ♀ - CAUD) ; Putumayo: Camino Viejo [San Francisco-Mocoa], 02-IV-2004, A. Garzón, on abaxial side of Asteraceae (1 ♀ - MUSENUV) .

Diagnosis: Antenna reaching laterally to the level of forewing pterostigma, antennal knob ellipsoid reddish-yellow with dark brown base and apex ( Fig. 9D ). Head and thorax mainly black, with abundant black pubescence ( Figs. 9B, C ). Wings infumate, pterostigma brown composed of two or three veinlets; hind wing trianguloid, with the area between CuP and posterior wing margin at the level of RP origin with three rows of cells; area between MP and posterior wing margin at the arch of CuP level with an extensive dark brown spot ( Fig. 9A ). Remarks: Until now, this species was known only from Brazil and Suriname ( Penny, 1977). Cordulecerus surinamensis is similar to C. elegans , however the hind wing shape of this species is more pronounced, the antennae are longer with the apical knob dorsally white, thoracic nota has a wide, longitudinal, light brown stripe, and abdomen has semitriangular light brown spots surrounded with black on the tergites. Here we provide the first records of this species from Colombia, with two specimens collected in two localities of the Amazon region.

Distribution: Brazil, Colombia, and Suriname.
