( Figs. 20 View FIGURES 16 – 24 , 55 View FIGURES 51 – 58 , 66 View FIGURES 62 – 71 )

Diagnosis. Frons black in middle with yellow margins, ocellar triangle brown, vertex yellow; face black with an inverted W-shaped central yellow spot; scape black; pedicel black with yellow dorsoapical spot; first flagellomere yellow; palpus black; scutum and scutellum black; legs black except base of fore tibia and a ring on middle of mid and hind tibiae yellow, tarsi whitish, base of first tarsomeres of fore tarsus and all distal tarsomeres dark.

Description. Holotype male. Body: 3.0 mm. Wing: 2.7 mm. Thorax: 1.5 mm. Head ( Fig. 66 View FIGURES 62 – 71 ). Frons black in middle with yellow margins, entirely clothed in fine pale microtomentum; ocellar triangle brown, coloration contiguous with vitta; vertex yellow. Face black with inverted W-shaped central yellow spot and numerous conspicuous thin yellow setae. Parafacial yellow. Gena black with slender yellow setae. Antenna: scape black; pedicel black with dorsoapical yellow spot; first flagellomere yellow; arista sub-basal dorsal with 11 dorsal and 4 ventral rays. Mouthparts: proboscis pale yellow; palpus long, black about 3 times longer than wide, with truncated apex, slightly enlarged distally, with black setae; clypeus black, bulged. Postcranium dark brown to black, with lateral margin of occiput yellow with a band of dense whitish microtomentum around lateral margin of eye; setae sparse and thin, yellow. Eyes with interfacetal setae short, fine, quite numerous. Setae: 1 lateral and 1 medial vertical pairs long, of same length; 1 divergent and short postocellar pair; 1 orbital pair on midlength of frons, as long as vertical setae; 1 pair of ocellar setae inserted laterally to ocellar triangle, downward; ocellar triangle with several short weak setae; all setae yellow.

Thorax. Scutum black with dense thin yellow setae, dorsal surface punctate; lateral and posterolateral margins of scutum and entire scutellum with whitish microtomentum, denser on notopleuron. Subscutellum black. Pleurae with whitish microtomentum, denser on upper portion of anepisternum; a large shiny area, without microtomentum, extending from lower portion of katepisternum to upper portion of anepisternum. Setae: 1 postpronotal; 2 strong notopleural; 1 postalar; 1 dorsocentral prescutellar, 1 short acrostichal prescutellar, slightly more robust than covering setae; 2 pairs of short yellow scutellar setae; katepisternum with 1 long strong seta and few short weak setulae; acrostichal and dorsocentral prescutellar setae yellow, remaining setae brown.

Legs black except for base of fore tibia and a ring on middle of mid and hind tibiae yellow, tarsi whitish, base of first tarsomere of fore tarsus and all distal tarsomeres dark. Mid tarsus with short black spines on tarsomeres 1– 4. Apicoventral spine of mid tibia very short and stout, not reaching middle of first tarsomere. Femora lacking ventral series of outstanding setae.

Wing ( Fig. 55 View FIGURES 51 – 58 ) uniformly brown, slightly darker basally and on costal margin; the longitudinal fold crosses the dm-cu cross vein in the middle.

Abdomen dark brown, shiny, with pale microtomentum and scattered very short, thin, brown setae. Tergite 1+ 2 with longitudinal median unsclerotized line from base to middle of segment, widened distally. Terminalia: cercus short, inconspicuous externally; not dissected.

Female. As in the male. Terminalia ( Fig. 20 View FIGURES 16 – 24 ): syntergosternite 7 complete, well sclerotized; sternite 8 with a short sclerotized spine-like projection on posterior margin; cercus broad.

Type material. Holotype 3 ( INPA): BRASIL, Amazonas, Manaus/ Reserva Km 41, PDBF / 16–17.ii.2005 / sub-bosque, R. Querino col. Condition of holotype: left wing removed from body and glued on triangle of paper; abdomen glued with mid and hind legs; lateral of abdomen damaged and some aspects of abdomen cannot were observed.

Paratype. BRASIL, Amazonas, Reserva Adolpho Ducke, Baixio, Trilha Leste/ Oeste, 03-17.viii.2007, Armadilha Suspensa Amarela, Dossel, Barbosa, B. S., Freitas, G., Feitosa, M. cols., Ƥ ( INPA).

Distribution. Brazil (Amazonas).

Etymology. This species is named in homage to Manaus, the type-locality.

Comments. The holotype, the only available male specimen of this species, was not in a condition to be dissected, because it could be seriously damaged. However, the external characters and the female terminalia are sufficient to distinguish this species from the remaining members of Neoscutops with an inverted W-shaped central yellow spot on the face.
