Etymology. The species is dedicated to Aristóbulo López Ávila.
Diagnosis. Pronotum well developed carinae, sulcated oval subepiphallic sclerite in vertical position.
Description. Measurements in Table 1 View TABLE 1 .
Male. Head. Antennae brown with 10 antenomeres, metallic green and black in life. Scape and pedicel yellow. Eyes globular, brown. Integument of vertex rough, with seven pairs of tubercles. Fatigium edges raised ( Fig. 1 View FIGURE 1 A), edges gather to carinulas. Front yellow, metallic green in life. Integument of genae smooth ( Fig. 1 View FIGURE 1 A), post-ocular area black.
Thorax. Pronotum. Anterior and posterior margins of pronotum heart-shaped, in dorsal view ( Fig. 1 View FIGURE 1 B). Well developed carinae, sulcated. Integument smooth. Two black fringes from anterior to posterior part. Integument predominantly green in life. Upper edge of anterior margin forms an obtuse angle. The bottom edge forms a curve in metazona; posterior edge has an angle of 90°. Lateral lobes yellow. Micropterous. Tegmina with yellow edges and brown central area. Spine between carinula and inner carina on hind femur.
Abdomen. Black midline until the sixth tergite, seventh and eighth red, other tergites are black. Yellow abdominal sternites. Thick cerci, sharp and curve ends directed toward the center ( Fig. 2 View FIGURE 2 A). Subgenital plate in lateral view rounded, upper margin in axial view straight ( Fig. 2 View FIGURE 2 B). First tergite black, second to sixth tergite green, seventh and eight tergite red. Metallic blue subgenital plate in life.
Phallic complex. Ectophallic sclerites robust, acute in lateral view. Epillus round, lateral edge bent downward ( Figs. 2 View FIGURE 2 C, 3B). Rounded end of lophae, bent downward in axial view. Subepiphallic sclerite curved, in vertical position ( Fig. 2 View FIGURE 2 C, thick line), upper edge in contact with epiphallus. Endophallic sclerite in dorsal view oblong, anterior part rounded; thin arms, acute end toward to center. Sclerite shape is similar to a sickle ( Figs. 2 View FIGURE 2 D, 3C).
Holotype 3: COLOMBIA. Caldas. Norcasia, Mouth of Manso River in La Miel River. 74º 46’ 25” W 5º 40’ 32” N. 220m. J. M. Carvajalino. 5–Jun–2009. MFP n°143. Deposited in Instituto de Ciencias Naturales [ ICN – 46098] at Universidad Nacional de Colombia, Bogotá.
Etymology. The species is dedicated to Aldo Malavasi

Description. Male ( Table 2) Head. Antennae black with 10 antenomeres. Scape and pedicel yellow. Eyes globular, black. Fastigium edges raised ( Fig. 4 View FIGURE 4 A). Clypeal triangle of front brown. Front yellow. Integument of genae and vertex rough, brown Rough, brown ( Fig. 4 View FIGURE 4 A). Six pairs of blue tubercles.
Thorax. Pronotum. Straight anterior margin, posterior margin heart-shaped. Well developed carinae on metazona. Pronotal zone divided by a sulcus (sulcated). Two diagonal sulcis which form a “V” between prozona and metazona in dorsal view. Integument of metazona rough ( Fig. 4 View FIGURE 4 B). Anterior edge of lateral lobe forms an obtuse angle. Posterior edge forms an angle of 90°. Green dorsally and yellow laterally. Micropterous. Tegmina with green veins and black membranes ( Fig. 4 View FIGURE 4 B). Spine between carinula and inner carina on hind tibia.
