Membracidae comprises about 400 genera and over 3,200 species (^{McKamey, 1998}; ^{Dietrich et al., 2001}; ^{Flórez et al., 2015}) grouped into nine subfamilies, eight of which are restricted to the New World (^{Deitz et al., 2008}; ^{Campodonico, 2015}). The distribution of this family is cosmopolitan, in the Neotropical region are reported 216 genera and approximately 1,600 species (^{Wood, 1993}; ^{McKamey, 1998}; ^{Dietrich et al., 2001}; ^{Flórez et al., 2015}).

The genus Umbelligerus was described by ^{Deitz in 1975} to include ornamented species of treehoppers with an antler-like pronotum. It is characterized by the stalked ocelli and compound eyes, pronotum with umbelliform process dorsally, not concealing the scutellum or the forewings in repose; the forewing and hindwing with one r-m and one m-cu crossvein; tibiae not foliaceous; metatibiae with cucullate setae in row II, first tarsomere has one cucullate setae apically and the abdomen without conspicuous punctuation (^{Deitz, 1975}; ^{Flynn, 2014}). The genus has nowadyas five described species: Umbelligerus peruviensis ^{Deitz, 1975}, Umbelligerus furcillatus Sakakibara, 1981, Umbelligerus woldai Sakakibara, 1981, Umbelligerus convergens ^{Flynn, 2014} and Umbelligerus stockwelli ^{Flynn, 2014} distributed in Central and South America (^{Cryan & Deitz, 2000}; ^{Flynn, 2014}). Umbelligerus peruviensis is known from Brazil, Peru and Venezuela (Fig. 1), whereas U. furcillatus is restricted only to Brazil, U. woldai in Costa Rica and Panama, U. convergens is only in Panama, and U. stockwelli know from Panama and Costa Rica.

Umbelligerus peruviensis is the type species of the genus and its features are, the head with elevated vertex and bearing ocelli on dark elevated nodules, compound eyes dark (Figs. 2-4); pronotum with white longitudinal band laterally on each side (Fig. 2, 4), with black umbelliform process dorsally; elevated central stalk and simple branch; distally presents two anterolateral branches each of which has three secondary branches (Fig. 2); scutellum exposed with white areas laterally ranging to the back; legs slightly darker distally (Fig. 2-4) and abdomen with black apex dorsally. According with ^{Flynn (2014)} U. peruviensis is most closely related to U. furcillatus but U. peruviensis has a small prong present in each of the posterior branches of the pronotal extension (Fig. 2). The specimens of U. peruviensis of the type series (1♀ and 2♂) and the reviewed by ^{Flynn (2014)} (2♀ and 3♂) was collected in the years 1952, 1984, 1992, 1993 and 1999, in the rainforest by blacklight traps and mercury vapor lamp at altitudes of 140, 240 and 900 m.

One male specimen deposited at the Museo de Entomología de la Universidad del Valle, Santiago de Cali, Colombia (MUSENUV: 27748) was examined. It is from Amazonas Leticia, San Martín de Amacayacu. 3°42’19”S, 70°20’26,1”W, altitude 70 m. 12-13.VIII.2015. White led light trap located in the forest canopy (10 m high); collectors: R. González, N. Calderón, O. Saenz and N. Carrejo. The determination of the specimen was carried out using the ^{Flynn (2014)} key and the revision of original description of ^{Dietz (1975)}. The photos were taken using a Nikon SMZ 1500 stereo microscope, a Nikon DS-Ril U3 camera and finally were edited with NIS-Elements software.

This finding is the first report of the genus and species for Colombia. It is noteworthy that the specimen was collected in the lowest altitude known for species (70 m) and using white led light traps in more than 10 meters above the ground, providing an interesting fact about the habitat of these insects.
