First record of the sand fly Warileya (Hertigia) hertigi from Antioquia, Colombia

Abstract

Introduction: The genus Warileya is one of the least-known taxa of sandflies, comprising only nine species, i.e., W. (Warileya) phlebotomanica, W. (Hertigia) hertigi, W. (W.) rotundipennis, W. (W.) nigrosacculus, W. (W.) yungasi, W. (W.) fourgassiensis, W. (W.) lumbrerasi, W. (W.) euniceae and W. (W.) leponti. Objective: To document the presence of a species of the genus Warileya in Antioquia, Colombia. Materials and methods: Sandflies were collected in a cavern of the Cañón del Río Claro Natural Reserve, of the municipality of San Francisco, Antioquia department, Colombia. Phlebotomine sampling was carried out using a CDC light trap during three consecutive nights in May of 2008. Taxonomical determination was based on a revision of the type material of the species and through the use of standard keys for American sandflies. Results: Five male and two female sandflies were taxonomically identified as W. (H.) hertigi. In both sexes, the absence of setal scars in the anepisternum, proepimeron and clypeus; the presence of two transverse rows of setal scars in the tergites; and the short length of the vena gamma were notable. Conclusion: The finding of W. (H.) hertigi increases the number of sandfly species found in Antioquia department to 64. In total, 164 sandfly species have been recorded in Colombia.
