Redescription. Female ( Figure 1g, i View Figure 1 )

Body length 12 – 13 mm. Vestiture uniformly brown or grey-brown with white stripes on pronotum and elytra; pronotum with two pairs of whitish stripes, one on disc and the other on margins; elytra with contrasting white stripe along suture (typical form, Figure 1g View Figure 1 ) or greyish-brown, with less contrasting stripe along suture, and white stripes on middle half of 3° interval, anterior third of 5° interval, and 7 – 8° intervals, the latter stripe interrupted near middle-length and curved towards 4 – 5° intervals on posterior third (variety, Figure 1h View Figure 1 ). Rostrum 1.05 – 1.10× as long as wide at apex; lateral carinae strong, subparallel. Eyes round, convex. Scape reaching anterior margin of pronotum; funicular article 2, about twice as long as article 1. Pronotum 1.15 – 1.20× as wide as long in females; sides curved; disc flat, slightly rugose. Elytra oval, 1.50 – 1.60× as long as wide; sides moderately curved and not abruptly narrowed towards apex; apical tubercles large; intervals about 2 – 2.5× as wide as punctures of striae. Front femora 2.95 – 3.10× as long as wide and 1.20 – 1.30× as wide as hind femora. Front tibiae with large mucro and 9 – 10 large denticles on inner margin; middle tibiae with small mucro and lacking denticles; hind tibiae lacking mucro and denticles; corbel of hind tibiae narrow, squamose. Ventrite 5 slightly shorter than ventrite 2.

Female genitalia

Ovipositor slightly shorter than abdomen, lacking rows of long setae on posterior third, on external side of baculi. Spermatheca ( Figure 3h View Figure 3 ) subcylindrical, small (0.5 mm); nodulus conical, short; ramus indistinct; spermathecal duct about 4× as long as spermatheca.

Male ( Figure 1h View Figure 1 )

Body length 10.5 – 13 mm. Smaller and more slender than females. Pronotum about as wide as long. Elytra about twice as long as wide, with smaller apical tubercles. Ventrite 5 about twice as long as ventrite 2, apex slightly inwardly curved.

Male genitalia ( Figure 4g, h View Figure 4 )

Body of penis about 1.90 – 2× as long as penis apodemes; apex arrow-shaped, slightly truncate; ostium about 3× as long as wide; endophallus with distinct spiny area but lacking internal pieces.

Geographic distribution ( Figure 5a, d View Figure 5 )

Naupactus mimicus   is endemic to Brazil (Paraná and Santa Catarina states) and occurs mainly in the Araucaria forest, close to the limit with the Atlantic forest   .


Naupactus mimicus   was described based on a series of specimens (= syntypes) from Brazil, Santa Catarina   . The male from this location labelled as typus is herein designated as lectotype. Along with this specimen there is a female with the same data, herein considered a paralectotype   . Naupactus justus   was described based on a series of specimens (= syntypes), females and males, from Brazil, Paraná, deposited in the author ’ s collection (currently at the American Museum Natural History) and the Chicago Natural History Museum   . We designated the male of the AMNH as lectotype.

Naupactus mimicus   differentiates from N. xanthographus   because the pronotum is slightly wider and more rugose, the elytra are shorter and with smaller apical tubercles, the denticles of the front tibiae are larger, the corbel plate of the hind tibiae is narrower, the nodulus of the spermatheca is slightly longer, the apex of the penis is more truncate between the lateral points and slightly longer relative to its penis apodemes, and the ostium is also longer.

The types of N. mimicus   (Santa Catarina) and N. justus   (Paraná) are uniformly brown, with a contrasting white stripe along the suture of elytra and without other white stripes visible from dorsal view ( Figure 1g, h View Figure 1 ). In other specimens from Santa Catarina the vestiture is greyish, with less contrasting white stripe along suture, but with distinct white stripes along 3° and 5° intervals, and the distal half of the lateral stripe visible from dorsal view ( Figure 1i View Figure 1 ). This pattern is similar to that of the Brazilian variety of N. xanthographus   ( Figure 1c View Figure 1 ).
