Type material. Holotype Ƌ( Fig. 5A View FIGURE 5 ) “ Brasil, BA, Encruzilhada , 15º32’25’S – 40º50’12’’W, 10–12.XII.2007, J.A. Rafael; P C. Grossi & D. R. Parizotto col., Armadilha luminosa, 800m ” ( INPA) . Paratypes. Same data as the holotype one male and two females ( INPA) .

Type locality. Encruzilhada , Bahia, Brazil .

Etymology. The name is a combination of albi - (L. albus, white) and— pilosa (L. pilosos, hairy) in reference to the white seta on the body and wings.

Description. Body brown covered dorsally and ventrally by waxy pubescence. Wings with white pubescence on base and alternate spots of white pubescence over the veins.Very long white setae posterior to eye.

Head ( Figs. 5A, B View FIGURE 5 ; 7A View FIGURE 7 ). Head tawny with castaneous fascia between lateral ocellus and anterolateral vertex, triangular when viewed from dorsal side. Ocelli and eyes castaneous. Ocular tubercle developed, marked with piceous. Curved piceous fascia around anterior and anteromedial lateral ocellus, anterior and posterior cranial depressions piceous, piceous spot anterolateral to lateral ocellus on vertex. Posterior margin of eyes with long white setae. Internal margins of eyes piceous. Ventral head castaneous with blond setae. Postclypeus tawny with slender, castaneous central sulcus with nine transverse grooves, piceous within transverse groove connected medially by longitudinal piceous fascia parallel to central. Anteclypeus castaneous with tawny carina, covered with white setae. Mentum ochraceous, labium ochraceous with castaneous apex reaching metacoxae. Scape, pedicel and antennal flagella castaneous.

Thorax ( Figs. 5A, B View FIGURE 5 ; 7A View FIGURE 7 ). Pronotum and pronotal collar covered by white pubescence. Pronotum tawny, castaneous fascia on either side of midline expanding anteriorly and posteriorly before angling and fusing on midline or anterior margin and ambient fissure, piceous markings in paramedian and posterior half of lateral fissures, mark in paramedian fissure extending posterolaterally across disk toward posterior lateral fissure. Pronotal collar lateral angle projected laterally, wider than lateral margin of mesonotum, lateral margin convex, and the laterally pronounced. Mesonotum tawny covered by white setae, submedian sigillae piceous, medial lateral sigillae piceous covered by pubescence, scutal depressions piceous. Wing groove tawny covered by white pubescence. Cruciform elevation tawny covered by white pubescence, swollen centrally, posterior projections short, lateral surface flat, not covering first abdominal tergite posteriorly.

Operculum ( Figs. 5E View FIGURE 5 ; 7C View FIGURE 7 ). Male operculum tawny, semilunar with anterior margin straight and base posteromedially angled, lateral and posterior margins slightly convex; internal angles of operculum forming acute angle, not touching each other medially. Female operculum triangular, with posteromedial margin straight, lateral margin short and convex.

Wings ( Figs. 5A View FIGURE 5 ; 7A View FIGURE 7 ). Wings hyaline with alternated paired pile of white seta along margins of veins. Veins tawny becoming castaneous distally, except piceous arculus, piceous mark at node, and piceous along nodal line at intersections of veins. Forewings with eight apical cells, infuscation on all crossveins, on base of radius anterior 2, longitudinal infuscation in apical cells terminating as a spot on ambient vein in all but apical cell 2. Basal cell subcylindrical, rectangular, slightly longer than broad. Hindwings with six apical cells, venation tawny becoming castaneous distally except piceous anal vein 3, anal vein 3 with curved distal terminus. Jugal fold long, extending three quarters the length of anal cell 2. Anal cell 3 and anal cell 2 along anal veins 2 and 3 white.

Legs ( Figs. 5D View FIGURE 5 ; 7B View FIGURE 7 ). Fore coxae and trochanters castaneous covered by white setae. Fore femora with castaneous fasciae and spines, primary spine in a horizontal position in relation to femur, close to femur, secondary spine largest inclined to femoral axis, and very small tertiary spine near to secondary spine. Mesocoxae, metacoxae, trochanters, and femora tawny covered by white setae. Tarsi piceous, middle castaneous. Pretarsal claws castaneous with piceous tips. Meracanthus tawny, an elongated triangle, not reaching half the length of operculum. Female meracanthus of similar shape to male, extending over the anterior margin of operculum.

Abdomen ( Figs. 5A, D, F, G View FIGURE 5 ; 7A, B, D, E View FIGURE 7 ). Abdomen tawny, subcylindrical, tergites 1 to 6 covered by white pubescence. Timbal cover flat, posteromedial margin straight, angled anteriorly, small triangular apex acutely angled not reaching lateral metascutellar plate, lateral margin straight, almost meeting lateral margin of operculum. Male sternite I tawny, swollen medially, sternite II castaneous, slightly arched anteriorly, covered with white pubescence, posterior margin slightly margined with white setae. Remaining sternites tawny with white setae and white pubescence. Male sternite VII tawny, the anterior margin marked with castaneous, covered with white setae and pubescence, lateral margin straight becoming convex posteriorly, posterior margin straight. Male sternite VIII ovoid marked with castaneous spots anteriorly and on either side of midline in middle and near posterior of sternite, with white setae at apex. Female tergite 9 with the posterior margin almost forming a right angle with body midline in lateral view, ventral margins concave, lateral margins tawny with white setae. Female sternites tawny with anterior margins stained with castaneous and covered by white wax and setae. Female sternite VII posterior margin sinuous with obtusely angled notch on midline. Epipleurites tawny with white setae and white pubescence.

Genitalia ( Figs. 6 View FIGURE 6 ; 7D, E View FIGURE 7 ). Pygofer subcylindrical; pygofer distal shoulder anterior margin terminating in acute projection; dorsal beak absent, pygofer upper lobe absent; pygofer basal lobe continuous with lateral margin of the pygofer, extending about half pygofer length with rounded apex. Uncus longer than pygofer basal lobe in lateral view; uncal dorsal crest projected posteriorly not fused on midline; lateral branches of uncus projected anteriorly, lateral and internal margins sinuous becoming convex toward apex, forming an acute apical projection, apex of lateral branches of uncus with lateral and internal margins tightly concave. Ventral apophyses with internal margins concave, anterior margins straight, lateral margins slightly convex. Theca tubular with long vesica and extruded sclerotized cornuti ventrally in two rows.Vesica slender with a sclerotized region from base to apex, a sclerotized region with apical cornuti and central spine. Female dorsal beak piceous, shorter than ovipositor sheath in lateral view. Gonapophyses IX castaneous, ovipositor sheath piceous with white setae at apex.
