Etymology. Species named after Joseph Francisco Zikán (1881–1949), a Czech entomologist who greatly contributed to the knowledge of the Brazilian insect fauna in the first half of the last century. Zikán conducted expeditions to collect insects in several localities of the Atlantic Forest, mainly in the Parque Nacional do Itatiaia (Itatiaia National Park) area, where he worked as a naturalist for many years. During his lifetime, Zikán assembled large collections, mainly Lepidoptera, Coleoptera, and Hymenoptera, which are now housed at the Instituto Oswaldo Cruz (IOC) (Rio de Janeiro).

Diagnosis. This species is distinguished from Bambuina bambui by the following characters: proximal part of males FWs folded, metanotal glandular structures absent. Male: FWs shorter than B. bambui , not surpassing the posterior margin of first abdominal tergite, without longitudinal vein; PsP1 inner margin short, outer margin elongated, pointed; PsP2 less developed. Female: copulatory papilla rounded, proximal margin flattened, with central, distal protuberance rounded.

Dorsum pubescent, light to medium brown, marbled ( Fig. 2B View FIGURE 2 ). Occiput and vertex light to medium brown ( Figs 2B–D View FIGURE 2 ). Fastigium medium brown, longer than wide, narrower than scape, separated from vertex by thin line yellowish brown. Three ocelli present, rounded, central flattened at bottom ( Fig. 2A View FIGURE 2 ); eyes obovate ( Figs. 2C–E View FIGURE 2 ). Antennal scape inner half medium brown, outer half light brown ( Figs. 2A, C–E View FIGURE 2 ). Antenna not annulated; antennomeres medium brown, uniform ( Fig. 1 View FIGURE 1 ). Frons medium brown, with two maculae light brown below antennal scapes, four spot circular, light brown, on inferior part, two horizontal lines light brown below eyes ( Fig. 2A View FIGURE 2 ). Frontoclypeal suture yellowish brown, with two dark brown spots ( Fig. 2A View FIGURE 2 ). Clypeus and labrum light brown; mandibles medium brown ( Figs. 2A, E View FIGURE 2 ). Maxillary palpi elongated, thin, medium to light brown, articles 3, 4, and 5 almost same-sized, apex of article 5 slightly upcurved, whitish ventrally ( Figs. 2A, E View FIGURE 2 ). In lateral view, gena yellowish brown from the eye margin to posterior border, medium brown on inferior portion, with an ascendant line medium brown on posterior border ( Figs. 2C, E View FIGURE 2 ).

Thorax. Pronotum DD wider than long, slightly pubescent, light to dark brown, marbled, median portion with two large blotches light brown ( Fig. 2B View FIGURE 2 ); inflated, divided by sagittal line light brown; cephalic margin almost straight, caudal margin slightly convex ( Fig. 2B View FIGURE 2 ); LL medium brown, ventro-cephalic angle rounded, ventro-caudal angle oblique, ventral margin gradually ascendant ( Figs. 2C, D View FIGURE 2 ). Legs. FI and II medium brown, annulated with light brown ( Fig. 1 View FIGURE 1 ). TI and II medium brown annulated with light brown ( Fig. 1 View FIGURE 1 ). TI with two same-sized apical spurs, TII with two same-sized apical ventral spurs. FIII light brown, three bands of several stripes medium brown on outer surface, apical third dark brown, annulated with light brown ( Fig. 1 View FIGURE 1 ). TIII medium brown, annulated with light brown. subapical spurs 4/4, the first near apical spurs; no spines between subapical spurs 1 and 2; 4-5 spines between subapical spurs 2 and 3, 3 and 4; serrulation above subapical spurs. Apical spurs more developed on inner side; inner apical spurs: median one longer (iam), dorsal almost same sized (iad), ventral smallest (iav) (iam>iad>iav); outer apical spurs: median one longer (oam), dorsal (oad) little longer than ventral (oav) (oam>oad>oav).
