Bambuina zikani Souza-Dias & Borille n. sp. Figs. 1–4 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). Type locality. Brazil, Rio de Janeiro, Itatiaia. Type material. Holotype, allotype, and paratypes: 5 males and 4 females (MNRJ); 1 male and 1 female (MZSP).

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. Description. Male. General body coloration in several shades of brown, marbled (Figs. 1, 2). Head. Head elongated, in lateral view (Fig. 2E). Dorsum pubescent, light to medium brown, marbled (Fig. 2B). Occiput and vertex light to medium brown (Figs 2B–D). 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); eyes obovate (Figs. 2C–E). Antennal scape inner half medium brown, outer half light brown (Figs. 2A, C–E). Antenna not annulated; antennomeres medium brown, uniform (Fig. 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). Frontoclypeal suture yellowish brown, with two dark brown spots (Fig. 2A). Clypeus and labrum light brown; mandibles medium brown (Figs. 2A, E). 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). 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). Thorax. Pronotum DD wider than long, slightly pubescent, light to dark brown, marbled, median portion with two large blotches light brown (Fig. 2B); inflated, divided by sagittal line light brown; cephalic margin almost straight, caudal margin slightly convex (Fig. 2B); LL medium brown, ventro-cephalic angle rounded, ventro-caudal angle oblique, ventral margin gradually ascendant (Figs. 2C, D). Legs. FI and II medium brown, annulated with light brown (Fig. 1). TI and II medium brown annulated with light brown (Fig. 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). 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). Basitarsi I, II and III anteriorly light brown, posteriorly medium brown, pubescent (Fig. 1). Abdomen. light to medium brown, marbled (Fig. 1). Supra anal plate light to medium brown, anterior margin concave, distal angles rounded, posterior margin straight (Fig. 2H). Subgenital plate medium brown, light brown centrally, anterior margin sub-straight, posterior margin rounded (Fig. 2I). Cerci medium brown. Male. FWs medium brown, coriaceous, pubescent, short, not triangular (in comparison with. B. bambui) and not reaching posterior margin of first abdominal tergite (Figs. 1A, B, 2B); without developed veins (Fig. 4A); proximal part folded (Figs. 4B, C); apical part light brown, thickened, folded, glandular (Figs. 2B–D, 4).

Endophallus: End crest shaped, EndAp present (Figs. 3B, D). Female. Larger than male, coloration similar (Fig. 1). Micropterous, FW very reduced (Fig. 2G, red arrow). Supra anal plate pilose, light to medium brown, anterior margin slightly concave, posterior margin rounded (Fig. 2J); subgenital plate pilose, light to yellowish brown, anterior margin slightly concave, posterior margin centrally concave (Fig. 2K); ovipositor shorter than FIII. Female genitalia. Copulatory papilla rounded, proximal margin flattened, dark brown, with central protuberance rounded, distal, upper portion membranous (Figs. 3E–G). Remarks. Individual morphological variation was observed in the male genitalia of some specimens: the external lobe of PsP1 of the holotype is longer and the apex more acute than in paratypes.
