03B587DEFFD8FFA5FFDDF8DDB7BE25FF.taxon	description	This species has previously been recorded from Brazil, Ecuador, and Peru (Borror, 1942; Garcia Junior et al., 2022; Mauffray & Tennessen, 2019). It was common in the vegetation near still water and ponds along the ecotourism trail in the Reserva Playa Güio and in the macrophytes at Laguna Negra lake. One female was captured with the aid of the light trap installed at the beginning of the ecotourism trail.	en	Florez, Tatiana, Comoglio, Lorenzo, Pinzón, Tomás, Bota-Sierra, Cornelio A., Cano-Cobos, Yiselle (2023): A collecting trip to San José del Guaviare, Colombia, with the description of a new species of Perissolestes (Zygoptera: Perilestidae).

03B587DEFFD8FFA5FC89FF1DB6202710.taxon	description	This species is known to occur from Trinidad throughout South America to Bolivia and Brazil (Belle, 2002; De Marmels, 2015; Garcia Junior et al., 2022; Mauffray & Tennessen, 2019; Michalski, 1988; Vallejo & Ledezma, 2010; von Ellenrieder et al., 2017), thus it was expected to occur in Colombia, too. One male was caught perched on a tree branch in a still-water zone at the ecotourism trail in the Reserva Playa Güio.	en	Florez, Tatiana, Comoglio, Lorenzo, Pinzón, Tomás, Bota-Sierra, Cornelio A., Cano-Cobos, Yiselle (2023): A collecting trip to San José del Guaviare, Colombia, with the description of a new species of Perissolestes (Zygoptera: Perilestidae).

03B587DEFFD8FFAFFC89FC78B002223F.taxon	etymology	Etymology Latin rupestris, masculine, third-declension two-termination adjective derived from rupes. The species name means that lives on cliffs or rocks and refers to the rock walls that rise on the sides of the small stream where the type material was collected (Fig. 2 f). It is also a tribute to the pre-Columbian cultures of the area whose legacy survives in the form of rock paintings at the type locality (Fig. 3).	en	Florez, Tatiana, Comoglio, Lorenzo, Pinzón, Tomás, Bota-Sierra, Cornelio A., Cano-Cobos, Yiselle (2023): A collecting trip to San José del Guaviare, Colombia, with the description of a new species of Perissolestes (Zygoptera: Perilestidae).

03B587DEFFD8FFAFFC89FC78B002223F.taxon	diagnosis	Diagnosis The genus Perissolestes was introduced by Kennedy (1941) based on wing venation, and it currently includes 11 species that range from the Amazon in Peru and Brazil and the Guiana Shield in eastern South America to southern Mexico (Garrison et al., 2010). The males of this genus can be divided into two morphogroups: one with a well-developed internal subbasal tooth in the basal fourth of the cercus (Figs 5 b – c), in which we include P. rupestris together with P. klugi Kennedy, 1941, P. paprzyckii Kennedy, 1941, and P. remotus (Williamson & Williamson, 1924); the other group lacks the internal subbasal tooth or it is located close to the middle of the cercus. P. rupestris can be differentiated from P. klugi by the preapical process in P. klugi being not developed. P. rupestris can be differentiated from P. paprzyckii and P. remotus in dorsal view, by its medial convex lobe in the cercus afer the subbasal tooth (Figs 5 b – c) whereas in the other species the internal side of the cercus afer the internal basal tooth is concave. Although the genital ligula is not well developed it is similar to what is seen in P. klugi and P. parzyckii where the convex apical lobe is larger (Figs 5 g – h) compared to P. remotus. Females of P. flinti De Marmels, 1988 and P. remus Kennedy, 1941 are unknown. Kennedy (1941 a) used some structural characters, but mostly coloration, to key out females in this genus. However, the lack of an erect median spine in the hind lobe of the prothorax (Figs 6 b – c), and the point of attachment of vulvar styles ventral to the cerci (Fig. 6 e) will group P. rupestris females with P. guianensis (Williamson & Williamson, 1924) and P. castor (Kennedy, 1937). At the current state of knowledge, it is hard to separate these three female species. A detailed study of other structural characters, such as the intersternites, that have underscored their importance in distinguishing females in other groups where cercus morphology is similar to Perissolestes, such as Heteragrion (Stand-Pérez et al., 2019) or Hetaerina (Garrison, 1990), is needed to help diagnosing the females of this genus.	en	Florez, Tatiana, Comoglio, Lorenzo, Pinzón, Tomás, Bota-Sierra, Cornelio A., Cano-Cobos, Yiselle (2023): A collecting trip to San José del Guaviare, Colombia, with the description of a new species of Perissolestes (Zygoptera: Perilestidae).

03B587DEFFD8FFAFFC89FC78B002223F.taxon	biology_ecology	Biology Perissolestes rupestris sp. nov. was observed on a clear-water creek and streams with rocky beds, perched on vines hanging close to stone walls and on the riparian vegetation. It usually hangs with the abdomen bent dorsally from S 7 to S 10 with the wings opened to around 100 ° (Fig. 4 b), but may also sometimes hang with the wings closed (Fig. 4 a).	en	Florez, Tatiana, Comoglio, Lorenzo, Pinzón, Tomás, Bota-Sierra, Cornelio A., Cano-Cobos, Yiselle (2023): A collecting trip to San José del Guaviare, Colombia, with the description of a new species of Perissolestes (Zygoptera: Perilestidae).

03B587DEFFD8FFAFFC89FC78B002223F.taxon	distribution	Distribution and conservation Three localities are known for this new species, all of them in eastern Colombia, two in the foothills of the Cordillera Oriental (Colombian Eastern Andean Range), in the department of Casanare between 580 and 820 m a. s. l., and one 296 km to the southeast, in the Amazonian foothills at 270 m a. s. l. in the department of Guaviare (Fig. 1 a). None of these three locations lies inside a protected area. The rapid expansion of agriculture in this region during recent years may lead to the transformation of these localities and probably result in its extinction, therefore we consider it a threatened species.	en	Florez, Tatiana, Comoglio, Lorenzo, Pinzón, Tomás, Bota-Sierra, Cornelio A., Cano-Cobos, Yiselle (2023): A collecting trip to San José del Guaviare, Colombia, with the description of a new species of Perissolestes (Zygoptera: Perilestidae).
