Etymology.Named noveloiafter Dr. Rodolfo Novelo Gutiérrez, a great friend, teacher, and devoted odonatologist, whose special interest in the immature stages led him to make great contributions to the field of odonatology. His kindness and willingness to help have motivated several students and researchers to work with odonates in Latin America.
Description of holotype Head. Light blue except post frons, vertex, and occiput, which are black and finely sculptured, which makes them iridescent ( Fig. 7c), with two light brown diagonal light brown dashes lateral to the ocelli ( Figs. 5a–b). Labium and genae greenish blue. Frons angulated. When alive eyes blue with ventral portion green ( Figs. 7a–c). Rear of head black. Thorax.Black except middorsal stripe finely sculptured making it iridescent and light blue anterior lobe of prothorax, lateral sides of medium lobe of prothorax, triangular spots on anterior portion of mesepisternum, concave stripe on mesepimeron, metepisternum and metepimeron with a black notch above the posterior area of metapleural suture ( Figs. 7a–c). Venter pale yellow and pruinescent. Lateral margin of posterior lobe of prothorax rounded ( Figs. 5a–b). Legs: Coxae bluish grey; femora external surface black and inner surface grayish blue; tibia and tarsus light brown; spurs black. The spurs on femora increase in size from base to apex (seven in each metafemur), the spurs on tibiae decrease in size from base to apex (eight in each metatibia) ( Figs. 7a–c). Wings.Hyaline with dark brown venation and pt ( Figs. 7a–b), which overlies one cell and has a ratio between distal and proximal length of about 1:1.

Abdomen:Black except S1, S8–9, apical rings on S2–7, lateroventral portions of S3 and S7 light blue; lateroventral portions on S4–6 bluish gray ( Figs. 7a–c). Genital ligula.With four basal setae on each side, apical segment clubbed with lateral margins expanded in lateral view and directed backwards ending in a blunt tip, with a small inner fold ( Figs. 5c–d). Caudal appendages.Cercus forcipate and almost as long as S10, in lateral view ventral side slightly concave, with a ventral tooth in its inner margin, directed inwards, which can be easily seen in dorsal view, ending in a rounded tip, with external surface black and with inner surface covered with white pruinescense ( Figs. 5e–h); paraprocts small (0.3 of cercus) dorsally concave, dark brown ( Fig. 5e). Measurements.Abdomen: 28; FW: 18, HW: 17, total: 35 mm. Description of allotype Head:Dorsal area of head finely sculptured making it iridescent. Black except for occipital border green, a thin line bordering compound eyes, antefrons around vertex, base of mandibles, genae, ventral portion of labrum, and ventral half of rear of head yellowish green; postclypeus and dorsal portion of labrum bluish green; ventral portion of labrum and antennae brown ( Fig. 6a), rear of head mostly black. Thorax.Yellowish brown, except black middorsal stripe finely sculped and iridescent; anterior lobe of prothorax, concave stripe on posterior ¾ of mesepimeron, metepisternum, and metepimeron greenish gray ( Fig. 7b); venter pale yellow. Posterior lobe of pronotum with medial lobe slightly bilobate, bearing a pair of medio-lateral elevated ridges ( Figs. 7c–d). Mesostigmal plates smooth, with medial margins sclerotized, lateroapical portions raised with a black pit behind them ( Figs. 7c–d). Abdominal venter pale yellow. Legs: Coxae light brown; femora external surface light brown and inner surface yellowish brown, apex black, tibiae and tarsus yellowish brown, and spurs black ( Fig. 7b). The spurs on femora increase in size from base to apex (seven in left and eight in right femur), the spurs on tibiae decrease in size from base to apex (eight in both metatibia), tarsal claws well developed. Wings.Hyaline with dark brown venation and pt ( Fig. 7b), which overlies one cell and has a ratio between distal and proximal length of about 1:1. 12 Px in FW, and10 Px in HW. Abdomen.Same pattern as males except green instead of blue and brown instead of black, also S8–9 brown and anterior margin of S9 and S10 blue ( Fig. 7b). Cercus brown, semitriangular in lateral view, half as long as S10, triangular in dorsal view, almost in contact at base, gonapophyses finely serrulated, styli brown, as long as cerci ( Fig. 6b). Measurements.Abdomen: 29; FW: 19, HW: 18, Total: 36 mm. Variation in male paratypes. number of spurs on metafemur: 6–8; on metatibia 7–10. Px 10–13 inFW, Px 9–12 inHW. Light coloration goes from light green to light blue ( Figs. 5a–b), some specimens are mostly green. The light colored metepisternal stripe can be divided in two small stripes one close to the coxae and the other close to the alar suture ( Fig. 7a). Amount of pruinescense on inner surface of cercus varies from totally covered to none ( Figs. 5f, h). Measurements:Abdomen: 28–29; FW:18–19, HW: 17–18, Total: 35–36 mm. Variation in female paratypes.Light coloration goes from light green and blue to brown, across some yellowish tones. Measurements:Abdomen: 28–30; FW: 20–21, HW: 19–20, Total: 35–37 mm.
Differential diagnosis.Males of this species can be placed in group M- 4 in Garrison (2009), because distance between bases of cerci is larger than 0.50 of the basal width of each cercus, wings are hyaline, cerci do not have a complete elongated seam and in lateral view are three times the length of paraprocts ( Figs. 5e–h). Within this group T. noveloishares the absence of red coloration on abdomen only with T. demarara(Williamson, 1917); these two similar species can be differentiated because the cercus in T. noveloihas a ventral tooth on its inner side, directed inwards, which can be easily seen in dorsal view ( Figs. 5f–h), which is not present in T. demarara,whose cercus has instead an apical recurved tooth which is not present in T. noveloi.Another difference is the presence of a tubercle on hind margin of mesostigmal plate in both sexes in T. demararawhich is lacking in T. noveloi. The other species in Garrison’s M4 group can also be differentiated from T. noveloiby: paraprocts in lateral view almost as long as cerci in T. racenisi Bick & Bick, 1995, whereas they are about a third of the length of cerci in T. noveloi; ventral side of cerci convex in lateral view in T. rubricauda, while in T. noveloithey are slightly concave; cerci with a ventrobasal process in T. corbeti, which is not present in T. noveloi.Based on the morphology of its genital ligula, T. corbetibelongs in group Ma-5 of Garrison (2009), characterized by distal segment clubbed with lateral margin expanded in lateral view. Within this group the most similar species are T. williamsoniand T. rubricaudadue to the coloration blue in thorax and black in the rear of head, and the rounded shape of the lateral margin of prothoracic posterior lobe. Telebasis noveloican be differentiated from both because the lateroapical margins of the ligula are expanded in lateral view and directed backwards ending in a blunt tip. FIGURE. 5. Telebasis noveloimale: head dorsal view: a, predominantly blue specimen (Tadó, Chocó); b, greenish blue specimen (Unión Panamericana, Chocó); Tadó, Chocó: genital ligula: c, ecto-lateral view; d, lateral view; caudal appendages: e, lateral view; f, dorso-lateral view; g, dorsal view; h, dorso-lateral view (covered with white pruinescence). b. t.:blunt tip; i. f.:inner fold; t.: ventral tooth. FIGURE. 6. Telebasis noveloifemale: a, head dorsal view (Tadó, Chocó); b, S8–10 lateral view (Unión Panamericana, Chocó); Tadó, Chocó: prothorax and anterior region of pterothorax: c, dorsal view; d, lateral view. ml. r.:medio-lateral ridge; pit.:pits behind mesepisternal plates. Females lack mesepisternal pits lateral to mid-dorsal carina, ovipositor does not extend beyond S10 ( Fig. 6b) and dorsum of S10 lacks a supplementary transverse carina, they lack prothoracic horns, and have thorax coloration mostly light brown with a linear mesepisternal stripe ( Figs. 6a, c–d, 7b), which places them in Garrison’s (2009)group F5. Within this group, T. noveloishares the presence of a pair of medio-lateral tubercles on the posterior lobe of prothorax ( Figs. 6c–d) with T. brevis Bick & Bick, 1995, T. corbeti,and T. selaopygeDe Marmels, 1989, but it can be differentiated from all of them by the ridge-like nature of these tubercles ( Figs. 6c–d). FIGURE. 7. Telebasis noveloi:a, male in lateral view (Tadó, Chocó); Unión Panamericana, Chocó: b, pair in tandem; c, male dorsal view. Habitat and Ecology.This new species has only been so far found in three localities in the Chocólowlands ( Fig. 4), where it inhabits small ponds with emergent vegetation, and shares its habitat with Dythemis nigraMartin, 1897, D. sterilisHagen, 1861, Erythemis plebeja(Burmeister, 1839), Erythrodiplax andagoyaBorror, 1942, E. fusca(Rambur, 1842), Idiataphe cubensis(Scudder, 1866), Rhodopygia hineiCalvert, 1907, Pantala flavescens(Fabricius, 1798), Perithemis moomaKirby, 1889, O. cultriformisCalvert, 1907, O. sulphurataHagen, 1868, M. ocellataMartin, 1897, Tramea abdominalis(Rambur, 1842), T. binotata(Rambur, 1842), A. trilobatumLeonard, 1977, and Argia translataHagen, 1865.
