( Figs 12–20 View FIGURES 12–20 )

Description. Length based on alcohol preserved specimens. Male body: 1.57 mm (n = 3), varying from 1.3 to 1.70; wing length: 1.17 mm (n = 3), varying from 1.1 to 1.13. Female, body length: 1.4 mm (n = 3), varying from 1.3 to 1.5. Wing length: 1.2 mm (n = 3), varying from 1.1 to 1.3. Head ( Fig. 12 View FIGURES 12–20 ). Black, dichoptic. Eye dark red to black. Ocellar tubercle black, concolorous with occiput, with one anterior pair of more robust black setae and 2–3 minute pairs of black posterior setae. Frons ( Fig. 13 View FIGURES 12–20 ) black (brown in alcohol preserved specimens), slightly higher than wide, subparallel sided, with 4 pairs of minute black lateral proclinate setae. Ocelli dark reddish brown, lateral ocellus separated from eye margin by approximately diameter of lateral ocellus. Face narrow, inconspicuous. Mouth margin black. Occiput and postcranium black, subshining, sparsely brown dusted with covering of short proclinate blackish setae only dorsally, last two posterior setae more robust. Postcranium ( Figs 12, 13 View FIGURES 12–20 ) extremely developed, length subequal to eye length. Postgena developed, with semicircular keel connecting right side to left side; oral cavity with distinctly deep ventral sulcus. Antenna ( Figs 14, 15 View FIGURES 12–20 ) brown to black; only one flagellomere with minute inconspicuous distal stylus surrounded by short distinct setae. Proboscis higher than head height, mixed with brown and yellow, obliquely downward directed ( Fig. 12 View FIGURES 12–20 ). Clypeus black, prominent, bulging, almost reaching base of antenna, with 1 pair of ventral setae. Labrum black, shorter than longest diameter of eye. Palpus absent. Thorax. Pronotum brown with 2 pairs of setae, external pair more robust. Mesonotum black, subshining, with scattering of short, black setae, rather randomly distributed but posteriorly with rather distinct uniseriate row of setae (aligned as acrostichal and dorsocentral rows as in Eremoneura) with posterior “dorsocentral” setae larger. Postpronotal lobe yellow with 2 more robust setae and 2 weaker ones. Two supra-alar setae more robust than surrounding setae. Postalar callus yellow with black seta. Scutellum dark brown, subshining, with 2 pairs of setae, apical pair more robust. Notopleuron yellow with 3 pairs of setae, posterior most pair stouter. Mesopleuron brown, subshining, lightly gray-brown dusted with yellow marks on following: anepisternum anteriorly and narrowly dorsally, katepisternum obliquely dorsally, anepimeron dorsally, katepimeron posteriorly, and lower half of katatergite. Metapleuron with yellow colour on metakatepisternum. Anepisternum with 3–4 setae with one more robust than remainder. Legs. Yellow, some specimens with light brown colour on femora. Wing ( Fig. 16 View FIGURES 12–20 ). Hyaline; veins brown; costal vein circumambient; vein Sc incomplete, ending at about middle of Rs. R 2+3 originating from Rs about midpoint from R 1 to r-m crossvein. R 4+5 rather straight; r-m crossvein placed at basal quarter of cell dm; crossvein dm-cu longer than m-m crossvein; vein M 1 slightly curved basally, almost two times cell dm length; M 2 more distinctly curved than M 1. CuA 1 and CuA 2 well developed to wing margin. A 1 vein short, stopping at alular incision level; anal lobe not keel-shaped. Halter with brown stem, knob yellow becoming darker distally.

Abdomen. Tergites dark-brown to black, subshining. Tergites V–VII with narrow whitish band across posterior margin. Sternites yellow to brown. Tergosternite VIII ( Fig. 17 View FIGURES 12–20 ) thin, forming complete circular band. Male genitalia ( Figs 17, 18 View FIGURES 12–20 ). Circumverted 180°; yellow to light brown, except black gonostylus. Epandrium placed ventrally with apex curved inwards. Cercus subtriangular. Hypandrium placed dorsally, distinctly curved, with distinct elongate setae. Gonostyli fused, black sclerotized, with small setae distally, apex bilobate in dorsal view ( Fig. 18 View FIGURES 12–20 ). Anterior arm of aedeagal sheath elongate, thin ( Figs 17, 18 View FIGURES 12–20 ). Ejaculatory apodeme rather small, translucent. Lateral ejaculatory process well sclerotized. Female genitalia. Tergite IX thinner than preabdominal tergites. Tergite X slightly projected posteroventrally. Cercus small. Apical sternite longer than anterior ones. Vaginal furca indistinct, unsclerotized, translucent, with membranous connection to distinct sclerotized small sclerite distally ( Fig. 19 View FIGURES 12–20 ). Vaginal furca slightly darker in lateral view. Three spermathecae with three basal sperm duct, translucent, each one apparently leaving directly from opening of translucent vaginal furca; sperm pump ( Fig. 20 View FIGURES 12–20 ) elongate, coniform, darker distally continuing by thin elongate spermathecal duct with no apparent modifications and ending folded in half on itself with each half thin, elongate, of equal width, extremely thin at fold ( Fig. 20 View FIGURES 12–20 ).

Etymology. The specific epithet is a noun in apposition and refers to the common name of the anteater in Brazil, Tamanduá bandeira, which is the symbol of the Parque Nacional Serra das Confusões. In addition, it is also an honor to Deusiano Bandeira de Almeida, a professor at Universidade Estadual do Maranhão, Caxias.

Habitat. Specimens were hand-collected from unidentified flowers at Parque Nacional Serra das Confusões, Piauí state, Brazil, in typical Caatinga vegetation, one of the more arid areas in Brazil.
