(Figures 1–9, 26–27)
Coelana drakei Kramer, 1964: 269 –270, 287 (key to species, description, distribution, figures 108–109).
Diagnosis. Pygofer basally wide, narrowing toward apex, each inner dorsal process truncate at apex, doubletoothed ventrally (Fig. 5); base of aedeagus with long ventral projection and narrowed dorsal apodeme, shaft narrowed toward apex, strongly curved dorsally at apical third, with apex truncate (Fig. 9); anal tube with pair of short, rounded, ventral processes medially (Fig. 5).
Measurements (mm). Male holotype: total length 6.16; crown median length 0.70; transocular width 1.47; interocular width 0.83; pronotum median length 0.64; width between humeri 1.66; scutellum median length 1.02; scutellum maximum width 1.02; forewing length 4.84; forewing maximum width 1.51; frons basal width 0.64; frons length 1.02.
Description (male holotype). Structural characters as in generic description, except: frons with muscle impressions distinct (Figs. 2–3); clypeus, in lateral view, without gibbosity (Fig. 3); forewing with anteapical cells visible only apically (Fig. 4); hindleg femoral setal formula not visible in holotype. Male genitalia: in lateral view, pygofer wide basally narrowing toward apex with large ventral hook medially and long oblique suture separating basal and apical halves; each inner dorsal process truncate at apex, double-toothed ventrally; posterior margin rounded and macrosetae at apical third (Fig. 5). Subgenital plates slightly narrowed toward apex, each plate with length about three times basal width, and apex rounded with bristles (Fig. 6); without apical tooth in lateral view. Styles short and thickened, with bristles at apical third, and lateral margins without irregularities or undulations (Figs. 7–8). Connective about half length of style, with anterior branches more sclerotized than stem (Fig. 8). In lateral view, aedeagus enlarged and membranous on basal half; base with long ventral projection and narrowed dorsal apodeme; shaft narrowed toward apex, strongly curved dorsally at apical third, with apex truncate and gonopore apical (Fig. 9). Membranous anal tube with pair of short, rounded, ventral processes medially (Fig. 5). Female unknown.
Color stramineous to yellow with median small black spot at coronal apex (Figs. 1–3). Head, in frontal view, entirely yellow, without markings, except for coronal black spot extending to base of frons (Fig. 2); crown yellow, without markings, except for black apical spot (Fig. 1). Pronotum yellow, posterior margin and central portion dark yellow. Scutellum entirely yellowish (Figs. 1, 26). Forewing hyaline, yellowish, with veins of the same color, without markings (Fig. 4). Hindwing same as for forewing. Legs yellow with concolorous setae.
Geographical distribution. Bolivia.
Specimens examined. Male holotype (USNM), with following labels: BOLIVIA / # 1141 [no other data, printed white labels]/ Holotype Coelana drakei Kramer [printed white label with red borders, the word “ holotype ” printed in red and the remaining words handwritten in black].
Holotype condition. Right side of the thorax glued to a triangle. Left antennal flagella with middle and apical thirds missing, and right one with apical third missing. Left hindleg, right foreleg, and right midleg missing. Scutellum with a great central hole anterior to preapical fold. Forewings and hindwings in good condition. Abdomen dissected.
Comments. Coelana drakei is very close to Coelana modesta, but can be easily separated from the latter species by its smaller size and the characters of male genitalia, especially the ones given in the diagnosis.
