Oecetis carlibanezae Martín, Gibon & Molina, 2011, new species
Description
Oecetis carlibanezae, new species
Fig. 3
This species clearly belongs to a group of closely related species including O. scoparia Flint 1974, O. peruviana (Banks, 1924), and O. traini n. sp. (Fig. 14) that have tergum X divided into 2 structures: A dorsal lobe and a ventral paired lobe (Figs 3 A–F). Oecetis carlibanezae n. sp. is closest to O. scoparia, with which it shares the following characters:
The shape of the single dorsal lobe of tergum X, the presence of 2 ventral flaps of tergum X and the absence of a dorsal process on each inferior appendage.
Specific diagnosis. Oecetis carlibanezae can be diagnosed by its triangular ventral paired lobe of tergum X, each with a serrate ventral margin bearing one ventral tooth.
Adult. Length of each forewing 5–6 mm. Forewings each with R2+3 branched near apex of Sc (Fig. 3 A).
Male genitalia. Segment IX annular with small, triangular dorsal knob. Preanal appendages each with rounded apex. Tergum X divided in 2 portions: Ventral portion triangular with ventral tooth in lateral view (Fig. 3 B), divided into 2 lobes in dorsal view (Fig. 3 C); dorsal portion digitate in lateral view (Fig. 3 B), with single median dorsal lobe in dorsal view (Fig. 3 C). Inferior appendages elongate, each narrowed at tip, 3 times as long as width of base; dorsal margin sinuous and apex truncate in lateral view (Fig. 3 B); strongly curved to midline with ends nearly touching in ventral view (Fig. 3 D). Phallic apparatus short, slightly curved and broadened at apex in lateral view (Fig. 3 E); broadened at midlength and narrowed at tip in dorsal view (Fig. 3 F).
Holotype male. BOLIVIA: Béni: Lake Belen, near Trinidad, 14°27'29''S, 64°51'41''W, 26.v.2003, (IML).
Paratypes. One male, same data as holotype, (CBF-UMSA).
Etymology. This species is dedicated to our friend and colleague, Carla Ibañez.
