The median fascia in A. samaypatensis extends approximately on one-third of the costa whereas in A. bellus it extends on onesixth of costa. In A. samaypatensis the colour of the markings is darker than in A. bellus , especially in the basal-subbasal blotch. The distal markings (postmedian + preterminal) are more contrasted with respect to the interfascial areas in A. bellus than in A. samaypatensis . The male genitalia of A. samaypatensis are easily distinguished from those of A. bellus . In A. samaypatensis the cucullus is smoothly elongate and distally fingerlike, whereas in A. bellus the cucullus is subtriangular, ventrally spined, and with a distinct neck. The sacculus is pointed in both species but relatively longer and more sinuous in A . samaypatensis . The cornutus in both species is well sclerotized; the apical portion is curved downward in A. bellus , whereas it is porrect in A. samaypatensis . Fig. 1. Venation in Aspinipogon samaypatensis sp. n. Based on slide JBA20816. Dashed lines indicate obsolescent veins. Scale bars: 2 mm. Description.— Head : Typically tortricoid. Vertex with light brown scales. Frons light brown, slightly convex, nearly naked. Antenna brownish ochre, length ca. 0.5 as long as forewing costa, dorsally scaled with two rows of scales per flagellomere, ventrally ciliated, cilia less than 0.2 times width of flagellomere. Maxillary palpus inconspicuous. Labial palpus porrect, length (all three segments combined) ca. 1.3 times diameter of compound eye, uniformly and densely scaled; first segment short, second segment long, straight, and rough scaled, third segment short and straight; opening of organ of vom Rath in lateral position.

Forewing underside light brown, pale on the base, pale interradial marks on costa. Hindwing upperside uniformly light brown with brownish paler scales in area overlapping with forewing; fringe pale. Hindwing underside whitish. Abdomen : Dorsad brown grey, pale cream ochreous cephalad and caudad. Segment 8 in males with long modified scales projecting caudad covering genital segments. Male genitalia ( Figs. 3‒5 ) (based on three preparations) with tegumen simple; uncus as a small slight protuberance; socius short, hairy, appressed to tegumen; gnathos reduced to a small sclerotized lateral curved plate; anal cone slightly sclerotized; transtilla simple, continuous, slender but evident; valva well sclerotized, length 940–970 µm from the base of sacculus to apex of cucullus, costa fairly straight, length 580–620 µm from apex to base; cucullus simple, fingerlike, hairy, especially distally; sacculus long, sinuous, same length as costa of valva, strongly sclerotized, projected distally in a upcurved point; pulvinus absent; basal process simple; vinculum strong; basal shield of the juxta simple, semicircular, projected caudad and dorsad as a sclerotized plate, medially membranous; phallus ( Figs. 4, 5 , 7, 8 ) ca. same length as valva, with coecum penis simple, caulis absent, vesica complex, asymmetrical, membranous (no acanthae), with three main diverticula when fully everted, two basal, laterally arranged, left one bearing a single long saberlike, non-deciduous cornutus attached laterobasally, inwardly directed, and longitudinally striated (no deciduous cornuti detected in female genitalia corpus bursae), right one smaller, without sclerotization, a third diverticulum dorsal subconical, slightly directed to right, bearing three small diverticula and distally taking nonsclerotized gonopore at tip of a funnellike delicately membranous extension. Segment 7 in female without modified scaling. Female genitalia ( Fig. 6 ) (based on one preparation) with ostium broad, groovelike; sterigma slightly sclerotized; antrum extremely short, broad, unsclerotized; ductus bursae wide, strongly sclerotized, relatively short and continuous with corpus bursae, dorsoventrally flattened, slightly narrowed before cervix, left side posteriorly expanded in a sclerotized diverticulum; corpus bursae sub-spherical, covered with numerous well-developed acanthae individually arranged and in bands or clusters, ventrally with an accessory bursa membranous, but with complex folds (stained dark with chlorazol black); no distinct signum. Ductus seminalis ventrally connected to anterior membranous part of corpus bursae; no bulla seminalis detected. A single globular spermatophore without collum extracted. Anal papillae uniformly covered by strong and long hairs; posterior apophysis short; ovipositor short, stout. Figs. 2–6.

Biology and distribution.—The immature stages are unknown. Adults were collected in January (n = 3), February (n = 2) and October (n = 3) at middle elevations ( 1300‒1575 m ) in Bolivia , Santa Cruz Department , Florida Province, in the municipalities of Pampa Grande and Samaipata, localities of Achira, Agua Clarita, Hueco de la Pascana. The collecting sites are mainly transitional areas to Chaco forest. Etymology.—The specific epithet refers to the Quechuan word “Samaypata,” which translates as “height of rest.” Samaipata is the locality in Bolivia , where specimens of this new species were collected.
