A preliminary list of the picture-winged flies known from Columbia is supplemented by 15 species based predominantly on the materials from the National Museum of Natural History, Washington, D.C., USA and now contains 28 species, including Xycores igniceps gen. & sp. n. from Venezuela and Colombia. The new genus belongs to the subfamily Otitinae and is preliminarily assigned to the tribe Cephaliini by the combination of the high clypeus, strongly widened palp, setulose vein R1, and ejaculator with short sperm pump and long fan-like apodeme. It clearly differs from other members of the tribe by the combination of elongate, narrow, apically truncated fl agellomere 1, robust, mainly shining thorax with pair of microtrichose vittae, well developed proepisternal, postpronotal, acrostichal, 2 pairs of dorsocentral and scutellar setae, wing with entirely setulose vein R1 abdominal tergites devoid of microtrichia, sternites and abdominal pleura narrow, male genitalia with short epandrium, numerous (7–8) prensisetae arranged into a row along posterior margin, shallow hypandrium with pair of setulose pregonites, no postgonites or epiphallus, and an almost bare phallus with a pair of long spines submedially.
