Coelana drakei Kramer, 1964

( 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.
