34391125C934FFACFF9CDB83F3EAF9A2.taxon	description	Variation among paratypes Males. Antehumeral stripe coppery red in all paratypes, some males with a paler yellow basal ring on S 4 – 7. The amount of pruinosity in S 9 – 10 varies among the specimens. The variation in coloration between the specimens is probably related to preservation methods and postmortem differences. Pt surmounting four to five cells in Fw and four to four and a half cells in Hw. Px in Fw 24 – 27, Px in Hw 22 – 25. Measurements (length in mm): Fw 32 – 33; Hw 33 – 35; abdomen 40 – 44; total 50 – 54. Female. Pt surmounting four and a half cells in Fw and four in lef and four and a half cells in right Hw. Px 26 in lef, 27 in right Fw, 24 in lef, 25 in right Hw. Measurements (length in mm): Fw 34; Hw 34; abdomen 35; total 45.	en	Cano-Cobos, Yiselle, Montes-Fontalvo, Jenilee, Bota-Sierra, Cornelio A.

34391125C934FFACFF9CDB83F3EAF9A2.taxon	diagnosis	Diagnosis This species belongs to the Philogenia helena group sensu Bick & Bick (1988) due to the meso-ventral process of cerci projecting ventrad in lateral view less than its width. Ten species have been included in this group (Fig. 1): Philogenia berenice Higgins, 1901, P. compressa Dunkle, 1990, P. gaiae Vilela & Cordero-Rivera, 2019, P. helena Hagen, 1869, P. iquita Dunkle, 1990, P. macuma Dunkle, 1986, P. minteri Dunkle, 1986, P. peacocki Brooks, 1989, P. raphaella Selys, 1886, and P. zeteki Westfall & Cumming, 1956 (Bick & Bick, 1988; Brooks, 1989; Dunkle, 1990 a, 1990 b; Vilela et al., 2019). Philogenia realpei sp. nov. can be easily differentiated from all these species by the unique morphology of its paraprocts (Fig. 2 c, d) which are almost as long as the cerci, bear a sharp preapical middorsal process and directed laterodorsally, ending in a pointed tip, which is unique not only in the P. helena group, but also in the whole genus Philogenia.	en	Cano-Cobos, Yiselle, Montes-Fontalvo, Jenilee, Bota-Sierra, Cornelio A.

34391125C934FFACFF9CDB83F3EAF9A2.taxon	distribution	Distribution This species is known from two localities in Colombia (Fig. 1), one in the eastern part of the Cauca department, which is known as “ Bota Caucana ”, and another located in the department of Putumayo. Both localities are found in the western slope of the Eastern Cordillera of Colombia towards the Colombian massif. The Colombian massif divides the Andean mountain range into branches that give rise to multiple tributaries, which are the sources of the rivers that define the Colombian landscape ecologically and culturally (Guhl, 2016).	en	Cano-Cobos, Yiselle, Montes-Fontalvo, Jenilee, Bota-Sierra, Cornelio A.

34391125C934FFACFF9CDB83F3EAF9A2.taxon	biology_ecology	Biology Philogenia realpei sp. nov. was found on a fast-flowing, well preserved little stream, with sand and gravel substrates surrounded by a mix of boulders and exposed bedrocks (Fig. 4). It coexisted with other damselflies of the genera Polythore Calvert, 1917, Palaemnema Selys, 1860, and Heteragrion Selys, 1862.	en	Cano-Cobos, Yiselle, Montes-Fontalvo, Jenilee, Bota-Sierra, Cornelio A.
