27. NOTELA SCHAUS, 1901 View in CoL

Notela Schaus, 1901 . Type species: Notela jaliscana Schaus. 1901 . Trans. Ent. Soc. Wash. 1901: 324.

Adults. ( Figure 3D View FIGURE 3 , 11D View FIGURE 11 ) Head: male antennae bipectinated beyond basal half, filiform in females; antennal tufts present; third segment of labial palpus short, proboscis shorter than the head; ocelli reduced. Thorax: tarsal claws bifid; female frenulum with three bristles; prothoracic leg lacking scent pockets. Wings: males 13 to 17 mm, females 16 to 18 mm; accessory cell absent; forewing with round apex, ground color being a mix of white, brown, and gray; hindwing plain gray. Abdomen: caudal tuft present in males. Male terminalia ( Figure 8F View FIGURE 8 ): eighth tergite with midplate; eighth sternite heavily sclerotized, V-shaped. Uncus square shaped with lateral, dorsal lobes, crown-like appearance; socii strongly upcurved or bent arms; valvae basally very narrow and distally very wide, ventral part have a small setose lobe; costa with a hook-like apical tooth; costulae absent; SSO absent; juxta square shaped. Aedeagus short, wide at base, apex denticulate; vesica with a single, long cornutus; deciduous cornuti absent. Female terminalia ( Figure 9G View FIGURE 9 ): eighth tergite with lateral prominences; anterior apophyses short; ductus bursae short and tubular, sclerotized; corpus bursae ovoid; posterior apophyses long and thin; papillae anales membranous.

Diagnosis. Absence of the accessory cell on the forewing, male antennae bipectinate to near the apex, the distally widened valvae with an apical tooth and the large and specific position of the signum in the corpus bursae are in combination, unique to this monotypic genus.

Comments. According to Miller et al. (2021) Notela jaliscana shows two wing pattern phenotypes: the first has a long, sinuate black forewing streak (from the base along the anal fold, and upward to the outer margin). This streak is absent in the second form, which we figure ( Fig. 3D View FIGURE 3 ). The frenulum number in females varied on the specimens from the CNIN-UNAM, some had two, one or three bristles.

Distribution. Southwestern USA and Mexico.
