Type material. Holotype ♂ (deposited at CEUA): Co [Colombia] ce [Cesar department] Copey Vda Tierras Nuevas / Fca [farm] Los Caminos de la Vida Bos- / que [forest] 10̊13′34.0″N 73̊47′38.9″W 493 m / VSR [Van Someren-Rydon trap] fruta [fermented fruit] dia [day] 16 Mar 2013 C. / Valverde // [red label] HOLOTYPE ♂ / Udamopyga / iku Buenaventura, / Valverde-Castro & Wolff, 2020. [terminalia of holotype in good condition and dry-mounted and glued on a squared piece of card and pinned; remaining body parts removed for DNA extraction]. Mitochondrial COI barcode region available via GenBank accession number MT926455.
Diagnosis. Aspecies with the following, unique combination of character states in the male: apex of surstylus rounded and wide; vesica whitish and membranous in appearance, which contrasts with the rest of the phallus, which is dark and sclerotized; vesica, in lateral view, with a rounded ventral notch formed by the distal folds which make the vesica larger distally than proximally; distal section of the vesica folded inwards; juxta sclerotized, proximally dark brown and distally almost translucent; juxta sub-squared, large, with a deep notch medially.
Description. Male.
Terminalia. Abdominal sternite 5 with a widely V-shaped cleft; posterior margin of the male abdominal sternite 5 with a slight undulation halfway between the angle and the tip of the V, and a rounded distal expansion. Syntergosternite 7 + 8 yellowish, with short setae. Epandrium as high as long, yellowish with long and slender setae. Cercus straight (lateral view); cercal prong gradually tapering in the middle but distally as thick as the proximal part; cercal prong proximally yellowish and distally light brown; cercal prongs fused to tip; cercal prong with a proximal tuft of long, black, curved setae dorsally; cercal tip rounded with short, thin setae dorsally and ventrally. Surstylus medium, almost as long as ½ cercal length, with rounded and wide apex; surstylus with scattered setulae on anterior margin only. Pregonite finger-shaped, curved proximally and straight distally; pregonite yellowish proximally and light brown distally. Postgonite dark brownish with a slightly curved apex and one long seta anteriorly. Phallus with a distinct hinge between basi- and distiphallus. Basiphallus short, less than ½ phallic length and slightly broadening distally; basiphallus with a dorsal longitudinal keel. Distiphallus, in lateral view, slightly constricted at point of connection with basiphallus and gradually broadening distally; distiphallus well sclerotized dorsally and less sclerotized ventrally. Paraphallus tubular and gradually broadening distally, with dorsal margin curved. Vesica composed of two petal-like lateral plates; each petal-like lateral plate of vesica with a distal fold and a vesical proximal denticulated lobe; distal fold of vesica rounded, whitish and almost translucent; vesica, in lateral view, with a rounded ventral notch formed by the distal folds which make the vesica larger dorsally than ventrally; vesica whitish and membranous in appearance, which contrasts with the rest of the phallus, which is dark and sclerotized. Acrophallus formed of a capitis, lateral styli and a median stylus; lateral styli tube-shaped and with an outlet; capitis flat and simple; median stylus tube-shaped and with an outlet. Juxta slightly recessed within the paraphallus; juxta sclerotized, proximally dark brown and distally almost translucent; juxta sub-squared, large, with a deep notch medially.
Female. Unknown.
Distribution. NEOTROPICAL – Colombia (Cesar).
Biology. Udamopyga iku sp. nov. was collected on fermented fruit, only in tropical dry forests, which indicates anthropophoby or asynanthropy.
Etymology. The specific epithet, which should be treated as a noun in apposition, is given in honor of the Arhuaco indigenous people of Colombia, who identify themselves as Iku, which translates as “people” in the Ika language. Udamopyga iku sp. nov. was collected in the foothills of the mountain complex Sierra Nevada de Santa Marta, a territory ancestrally protected by the Arhuaco people. In the Iku view of the world, their role is not to own the land, but to protect life.
Remarks. Udamopyga iku sp. nov. resembles Udamopyga bartica (Curran & Walley, 1934) and Udamopyga malacophila Lopes, 1940 in some features of their terminalia. However, U. iku sp. nov. differs from U. bartica and U. malacophila in the shape of the apex of the surstyli, which is rounded and wide in U. iku sp. nov. (Fig. 5A–B) while acute in U. bartica and U. malacophila. Udamopyga iku sp. nov. can also be separated from U. malacophila by the shape of the vesica, which has a distal section folded inwards in U. iku sp. nov. (Fig. 5C) while this section is not folded in U. malacophila.
