03A087FA231EFF8AFF3D615AFDF0B82B.taxon	materials_examined	Material examined: Three specimens were collected (1 ♂, 2 ♀♀), we assigned them as conspecific due to their share of the same habitat in the same forest patch, their conspicuous coloration, and mainly the correspondence of male cerci and epiproct with the posterior portion of the female head. All three specimens are teneral, and the two females were reared from the last larval instar to the adult stage (one of them was kept alive and feed with small insects for five days, which allowed the coloration pattern to get very close to the mature pattern). CEUA: Holotype. ♀ teneral, CEUA 113500, 19 February 2019, COLOMBIA, Antioquia Department, La Forzoza Reserve, Anorí Municipality, El Roble Township, 7.001010, - 75.130792; 1,644 m a. s. l., Leg: R.

03A087FA231EFF8AFF3D615AFDF0B82B.taxon	etymology	Etymology: The color of this species is unique among the species in the genus, since its dark ground coloration is reddish-brown instead of the common dark brown or black. Thus we named it rufus from Latin, which means red.	en	Bota-Sierra, Cornelio Andrés, Novelo-Gutiérrez, Rodolfo (2020): Two new species of Colombian Epigomphus (Odonata: Gomphidae).

03A087FA231EFF8AFF3D615AFDF0B82B.taxon	diagnosis	Diagnosis: The typical color pattern of species of this genus usually alternates black or dark brown with yellow, green and light blue; this is the only known species that has reddish brown coloration as dark background color making it easily recognizable (Figs. 2 a – b). Epigomphus rufus shares with a group of 16 species, including most of the South American and some Central American species, its second pale antehumeral stripe reduced to a single small posterior spot (Table 1). Among them, the males of E. camelus, E. compactus, E. subsimilis, E. tumefactus, and E. verticicornis share with E. rufus cercus length shorter than S 10 length (Figs. 4 a, c), but males of E. rufus can be easily distinguished from all these species by cercus strongly curved downwards and with a sharp tip which is unique among all 33 known Epigomphus species (Figs. 4 a, c), and so is the shape of male epiproct by having two teeth, one apical and one subapical, on each lateroapical process (Figs. 4 a, c). As pointed out by Calvert (1920), these caudal structures of males perfectly match with structures on vertex, occiput, and posterior area of females’ head, including the C-shaped tubercles behind the posterior ocelli and the conical holes where cerci match on rear of head (Figs. 1 a, c – d), the females of only ten species in this group of Epigomphus are known (Table 1), unfortunately, the descriptions of the posterior area of the head are not meticulous for all of them, but in all the cases where the structures are well described E. rufus females can be easily distinguishable since no other has C-shaped tubercles behind the posterior ocelli or conical holes in the rear area and this combination of characteristics is expected to be unique as the shape of the male cercus and epiproct among the species in the genus.	en	Bota-Sierra, Cornelio Andrés, Novelo-Gutiérrez, Rodolfo (2020): Two new species of Colombian Epigomphus (Odonata: Gomphidae).

03A087FA2319FF86FF3D64CDFD9BBABC.taxon	etymology	Etymology: brillantina (to be treated as an indeclinable noun) is the word in Spanish for brilliantine, referring to something shiny.

03A087FA2319FF86FF3D64CDFD9BBABC.taxon	diagnosis	Diagnosis. Epigomphus brillantina shares with a group of 16 species, including most of the South American and some Central American species, its second pale antehumeral stripe reduced to a single small posterior spot (Table 1). Among them, the males of eleven species share with E. brillantina cercus length longer than S 10 (Figs. 8 e – f). Within this group, E. brillantina and E. quadracies are the only two species that share cercus with a pointed dorsoapical process curved downward easily observed in lateral view (Figs. 8 e – f), but E. brillantina can be easily distinguished from E. quadracies by the shape of its epiproct which has a rounded apical tubercle on each lateroapical process while in E. quadracies two apical points are observed (Calvert 1920; Kennedy 1946) (Figs. 8 b – d). Also, the median portion of the posterior border of epiproct has a quadrangular notch in E. quadracies (Calvert 1920; Kennedy 1946) that can be observed both in ventral and dorsal view, while in E. brillantina this notch is oval and is not easily observed in dorsal view since it is invaginated under the lateroapical processes of epiproct (Figs. 8 b – d). Furthermore, the dorsal slender projection of the vesica spermalis fourth segment is longer in E. brillantina compared to that of E. quadracies.	en	Bota-Sierra, Cornelio Andrés, Novelo-Gutiérrez, Rodolfo (2020): Two new species of Colombian Epigomphus (Odonata: Gomphidae).
