Figures 7 , 16 , 25 , 44 , 51 , 61

Type locality. Horco Molle, San Miguel de Tucumán, Argentina.

Description. Antenna filamentous; foreleg tarsomere 3 about one-half length of distal tarsomere; hindtibia with some setae longer than tibial diameter.

Holotype male. Length of body 14 mm., forewing length 20.5 mm., width 5 mm., hindwing length 20. mm., width 4.5 mm; wing span 42 mm. Coloration: Face ( Fig. 7 ) nearly all pale brown with small irregular dark brown area between and below antennal sockets, extended onto vertex as short dark brown band; dark brown behind antennal sockets; palpi pale brown; antennal scape and pedicel dark brown dorsally, pale brown dorsally; flagellum nearly all pale brown except apical ten flagellomeres; vertex ( Fig. 7 , 16 ) with anterior row complete, narrow reddish brown band from eye to eye, slightly produced posteriorly at middle; middle vertex row consists of small, submedial dark brown spots; posterior row limited to brown triangular area at middle; elsewhere exist small dark brown areas; pronotum nearly all pale yellow except lateral margin at posterior two thirds which are slightly extended medially subbasally and basally; pteronota nearly all pale brown with dark brown areas mostly laterally; scutelli pale brown with small dark brown line laterally; thoracic pleura mostly pale brown with predominate dark brown area on mesopleuron ventrally; coxae and trochanter pale; femora and tibia pale brown with numerous dark brown spots at setal bases; tarsi pale brown; wings without dark brown marks. Chaetotaxy: Face and vertex dorsally with pale setae; antenna with pale brown setae on scape, pedicel and flagellomeres; pronotum with all setae shorter than those on clypeus; forefemoral sense hair about equal to that midfemur and about 2 times as long as femoral diameter; hindtibia with some setae longer than femur diameter; ventral setae on distal tarsomere of foreleg longer than middle diameter of tarsomere, apically hooked; ventral setae on other legs as long as middle diameter of tarsomere, not hooked; female ectoproct with short setae ventrally. Structure: Distal labial palpomere elongate, slender; antenna weakly clavate, with about 32 flagellomeres; most flagellomeres about twice as long as wide; foreleg tarsomere 3 longer than 4, tarsomere I about twice as long as distal tarsomere which is slightly bent subapically. Male genitalia ( Fig. 51 ). With gonarcus narrow, moderately arched, narrowed apically; no mediuncus; parameres close together posteriorly and strongly sclerotized along mesal margin, less sclerotized along other margins; most of paramere strongly divergent laterally; sculpture not prominent.

Female. About as described for male. Female terminalia ( Fig. 61 ). With posterior gonapophysis swollen, elongate and narrowed apically about 5x longer than middle diameter; lateral gonapophyses elongate, separate, with many prominent scraping setae which are darkened apically; pregenital plate small with median tooth.

Distribution. Argentina.

Collection times. November to January.

Material studied. Holotype male, 2 male paratypes, 2 female paratypes.

ARGENTINA. Tucuman: Horco Molle, San Miguel de Tucumán, 16.XII.1970, L. Stange (1m, FSCA); same data, 18.I.1973 (1f, FSCA) ; 19.XI.1970 (1f, FSCA) .

Discussion. All of the specimens were collected at a porch light. The filamentous antenna is distinct from all other Navasoleon except N. leptocerus .

Etymology. This species is dedicated to Juan B. Lotti, formerly of Bertiolo, Italy and San Miguel de Tucumán, in recognition of his assistance in field work. Gender is masculine.
