description: Rhagovelia angustipes Uhler, 1894
(Figs. 5A, 6A, 7A, 8A, 19F, 20F, 24A)
Rhagovelia angustipes Uhler, 1894: 215.
Rhagovelia jagua Padilla-Gil, 2015: 86 (new synonym).
Diagnosis. Body length ~3.00 in the male and ~ 3.20 in the female. Antennomere II shorter than III. Tarsal formula 3-3-3. Fore and hind coxae and trochanters yellow (Figs. 5A, 7A). Middle coxa and trochanter black (Figs. 5A, 7A). Male foret ibia slightly curved (Figs. 5A, 21B). Male hind trochanter without spines. Hind femur with 4–5 spines in both males and females. Male hind femur slightly surpassing apex of abdomen, about as thick as middle femur (Fig. 6A). Ratio of male hind femur/tibia length ~0.98/1.00. Female hind femur not surpassing apex of abdomen, about as thick as middle femur (Fig. 8A). Male hind tibia only with an apical spur. Lateral margins of male abdomen tapering more or less evenly to apex (Fig. 5A). Female abdomen elongated, with lateral margins tapering more or less evenly to apex (Fig. 7A). Central shiny black areas on dorsum of abdominal segments V–VIII in the male and IV–VIII or V–VIII in the female (Figs. 5A, 7A). Female abdominal mediotergites I–II elevated, the remaining segments slightly depressed and forming a shallow trough. Female abdominal laterotergites elevated, almost vertical for last three segments. Male abdominal sternum VII with median carina, slightly depressed on both sides. Male abdominal segment VIII subcylindrical, with lateral margins bowed, shorter dorsally than mediotergite VII (Fig. 5A). Paramere and proctiger as in Figs. 19F, 20F. Specimens from Ecuador studied by Bacon (1956) have 8–10 small spines on the hind femur, instead of the typical 4–5 spines (De Kort-Gommers & Nieser 1969). The unusual number of spines also occurs in some Colombian male individuals, sometimes in only one of the two hind legs.
Distribution. Colombia: Antioquia (this work), Boyacá (this work), Caldas (this work), Caquetá (this work), Chocó (this work), Cundinamarca (Padilla-Gil 2015), Putumayo (Padilla-Gil 2015, Padilla-Gil 2016, Padilla-Gil 2019a, Padilla-Gil 2019b), Quindío (this work) (Fig. 18A). Costa Rica (Hungerford 1939). Ecuador (Gould 1931). Grenada (Uhler 1894). Martinique (De Kort-Gommers & Nieser 1969). Panama (Kirkaldy 1899). St. Lucia (Bass 2010). St. Vincent & Grenadines (Kirkaldy & Torre-Bueno 1909). Trinidad & Tobago (De Kort-Gommers & Nieser 1969). Venezuela (Kirkaldy 1899). Listed from Mexico by Kirkaldy & Torre-Bueno (1909), but this record is far from other occurrences of R. angustipes and needs verification. Recorded from Puerto Rico by Wolcott (1924) and Wolcott (1936), but identification was later corrected to R. collaris Burmeister, 1835 by Wolcott (1941) (Fig. 24A).
Comments. Padilla-Gil (2015) compared her new species R. jagua with R. tantilla and R. pacifica (= R. tantilla, new synonym), but not with R. angustipes. After examining the types of R. jagua and several series of R. angustipes from Costa Rica (Moreira et al. 2015) and Colombia (this work), we must propose the synonymy between both species. Although the male of R. jagua displays eight spines on the hind femur, instead of the usual 4–5 found in most individuals of R. angustipes, such variation had already been reported for the latter species in the literature (De Kort-Gommers & Nieser 1969). Other features typical of R. angustipes, such as body and leg measurements, the male hind tibia armed only with an apical spur, and the female with shiny black spots on the last 4 abdominal mediotergites are present in the types of R. jagua. Rhagovelia angustipes is herein recorded for the first time from Colombia, which is not unexpected due to its known distribution from Costa Rica and the Lesser Antilles south to Ecuador.
