the construction of two hydroelectric plants in Colombia: Betania and El Quimbo . The construction of Betania was authorized by the Colombian government in 1972 without an environmental impact analysis; it responded to the historical need to boost the economy in southern Colombia ( Pulido 2014 ). Betania is considered to be the first multiple-purpose hydro-energy use project on the Magdalena, the most important river in Colombian. The construction of Betania aimed to increase both the coverage and continuity of energy services, as well generate employment in the

not working out of necessity ( Fields, 2012 ; Banerjee and Duflo, 2012 ). The aim of this paper is to analyze the link between labor informality and poverty in Colombia. Quantitative evidence is revealed through two empirical exercises: first, the potential effect of a labor-formalizing policy on poverty indicators through changes in labor earnings is analyzed; second, the effect of the recent changes in labor informality on the extent of poverty in Colombia from 2002 to 2013 is examined. The article is organized into five sections. The first section presents an

Abstract

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 flagellomere 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.
