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.
