( Figs. 1 to 25)

Type species: Bambuina bambui , n. sp., here designated.

Etymology. Genus named after the Brazilian speleology team "Grupo Bambuí de Pesquisas Espeleológicas", of which the second author of this article is a member.

Diagnosis. Clypeus inflated; apical portion of male forewings short, rolled, hiding a hairy glandular area; metanotum non-glandular, bearing a pair of small dorsal spines; pseudepiphallic spines blade-shaped, its distal margin covered by short bristles.

Description. Eyes very prominent, sub-pyriform, superior border evenly rounded, inferior one acuminated. Three small ocelli present. Clypeus inflated. Tip of maxillary palpi globose, apical truncation occupying ca. 1/4 of the length of 5th joint. Male fore wings velvety, abbreviated, sub-triangular, bearing a single longitudinal vein; the apical portion rolled down, hiding a hairy glandular area. Metanotum non-glandular, bearing a pair of small spines on dorsum. Tibia I with one pair of apical spurs on inferior side; tibia II also with one pair of apical spurs on inferior side but some specimens show an additional small spur on the supero-internal point (the condition of this particular spur is occasionally asymetrical on the same individual, being present in one of the tibia II but absent in the other). Tibia III with median apical spurs the longest on both sides. Male subgenital plate with a median membranous area on the distal half, which narrows toward the tip. Phallic complex: without glands; pseudepiphallic spines blade-shaped, not tubular, distal emargination covered with short bristles; pseudepiphallic parameres I very large in relation to pseudepiphallic parameres II; ectophallic apodemes rather short and stout; ectophallic arc located anteriorly to the base of the pseudepiphallic sclerite; endophallic sclerite small, bearing a distinct, longitudinal, crest-shaped, dorsal apodeme. Female apterous; ovipositor shorter than hind femora.
