Morphological characteristics: male and female mostly brown ( Fig. 4G–H View FIGURE 4 ), mesepimeron and metepisternum with a black spot as in Fig. 7E View FIGURE 7 ; pectum pale brown, except anterior 0.25 of metapostepimeron black ( Fig. 7F View FIGURE 7 ). Genital ligula rectangular, internal fold barely developed, width less than 1/3 of S2 ( Fig. 9G View FIGURE 9 ), surface entire, no reaching S2 ( Fig. 9H View FIGURE 9 ). Male cerci long, strong basal tooth projected ventrally; edge of medial portion without denticles; primary curvature type III ( Fig. 11C View FIGURE 11 ); secondary curvature type II ( Fig. 11D View FIGURE 11 ). Paraprocts reduced, globose, without apophyses, less than 1/3 of the length cerci ( Fig. 11D View FIGURE 11 ). Lateral valves of the ovipositor with a row of small denticles increasing in size to the apex; cerci almost twice the length of S10; dorsal margin of basal plate longer than ventral ( Fig. 14D View FIGURE 14 ); ventral margin split ( Fig. 14C View FIGURE 14 ).

Remarks: This rare species has a large area of distribution, it has been recorded from six localities in Surinam, Guyana, and Peru ( Belle 1997; von Ellenrieder et al. 2017). Recently it was reported for the first time in Colombia for the Guaviare department (Flórez et al. 2022). Here, we provide the second record for the Orinoco region (Meta department) ( Fig. 17 View FIGURE 17 ).
