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.

Figs. 1

Fig. 4
). Hindwing same as for forewing. Legs yellow with concolorous setae.
Geographical distribution.

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.
