Morphological characteristics: male and female mostly brown, ( Fig. 4I–J View FIGURE 4 , 7G–I View FIGURE 7 , 13A–C View FIGURE 13 , 23 View FIGURE 23 ), except the antehumeral dark stripe, mesepimeron with a dark-brown stripe; pectum pale with four black spots, two at the end of the metathoracic suture and two triangular in the metepimeron. Genital ligula rectangular, internal fold width more than 1/3 of S2, surface entire ( Fig. 9I View FIGURE 9 ), reaching anterior fold of S2 ( Fig. 9J View FIGURE 9 ). Male cerci long, with a basal subtriangular expansion; inner edge of medial portion irregular, reduced; primary curvature type II ( Fig. 11E View FIGURE 11 ), secondary curvature type II ( Fig. 11F View FIGURE 11 ). Apophyses of paraprocts almost 1/3 of the cerci length, apices ventrally curved ( Fig. 11F View FIGURE 11 ). Lateral valves of the ovipositor with a row of small denticles increasing in size to the apex; cerci not surpassing the length of S10; almost twice of the length of S10; dorsal margin of basal plate longer than ventral ( Fig. 14E View FIGURE 14 ).
Remarks: This species has a widespread and discontinuous distribution that ranges from Trinidad and Venezuela to Paraguay, southern Brazil, and northern Argentina ( De Marmels et al. 2022; Muzón 1993b; von Ellenrieder 2009b; Lencioni et al. 2022). Here we record this species for the first time in Colombia, the westernmost localities of its distribution.
