http://zoobank.org/ ACB16A3F-6593- 4AED-9150-5526F0AE7136 ( Figs. 4, 7 , 11 , 18–19 , 23 )

Diagnosis.—Forewing with a dark brown line on M2 near margin, only a spot on M1 with no dark brown bar to reniform spot, reniform spot a dark brown “upside down U” over a “right-side up U” ( Figs. 4 , 11 , see red circle); male genitalia with uncus tip pointed ( Fig. 18 ); female genitalia with signa on corpus bursae in two dorsal longitudinal lines ( Fig. 23 ).

Description.—Adult. Head: Scape posteriorly with a few dark brown scales, vertex only with yellow scales. Labial palpus ( Fig. 7 ) with first and second segments yellow and with a dark brown band anteriorly, only dorsally, third segment minute, dark brown on male, yellow on female. Proboscis with yellow scales throughout, without dark brown scales as proboscis curves under. Thorax: Average forewing length 8.25 mm (n = 8) in males, 8.42 mm (n = 7) in females. Forewing pattern as in Figures 4 and 11 , a dark brown line posterior to M2 near margin, only a spot on M1 with no dark brown line to reniform spot, reniform spot a dark brown “upside down U” over a “right-side up U” ( Fig. 11 , see red circle); no dark brown markings in radial area between reniform spot and postmedial line; first lengthwise line of zigzag between Rs3 and Rs4 shortened, almost a spot; second lengthwise line of zigzag between Rs4 and M1 very short, a spot; antemedial line incomplete. Abdomen: Third abdominal tergite with anteromedial dark spot and two lateral triangles, fourth tergite with anteromedial dark spot, fifth tergite with silver transverse band posteriorly ( Fig. 4 ). Male genitalia ( Figs. 18–19 ) uncus with very short, lateral setae; uncus "tip" pointed and prominent. Parateguminal androconia oblong, broader anteriorly. Valva with fibula, or sclerotized, fingerlike process extending only slightly beyond saccular margin. Juxta medially with a lightly sclerotized, single line. Phallus vesica with large spinules. Female genitalia ( Fig. 23 ) with ductus bursae with a square-like antrum about 2 mm in width, followed by two elongate, sclerotized structures within that are as wide as the band, strongly constricted and then ductus bursae three times as wide as antrum forming a lightly sclerotized pouchlike structure, then constricted at entrance to corpus bursae. Corpus bursae round, signum two longitudinal lines, half the length of corpus bursae. Ductus seminalis originating shortly after antrum.

Etymology.—The species epithet “ encisoensis ” is a noun derived from the name of the type locality, Teniente Agripino Enciso National Park in Paraguay, and “ ensis,” a Latin suffix meaning place. Distribution.—This species is found in one of the protected natural areas of the Paraguayan Chaco in the Teniente (Lieutenant) Agripino Enciso National Park in northwestern Paraguay, in the Argentinian Chaco in Las Brenas in northern Argentina, and in northern Venezuela just to the west and outside of Parque Nacional Aguaro-Guariquito.

Biological remarks.—Adults are attracted to lights. Nothing is known about the larval biology of this species.
