Diagnosis and comments

Nasutopedia borealis sp. nov. is very similar to N. micheneri Aguiar and Melo and N. morena sp. nov. due to the colour pattern of the integument, wing membrane and pubescence, with metasoma orange brown, wing membrane brown infumated with blackish microtrichia on apices and pubescence mostly black with distal portion of scopa pale white ( Figure 2 ). Nasutopedia borealis sp. nov. is easily distinguishable from the other two species by the terga being completely smooth, while Nasutopedia micheneri and N. morena sp. nov. have at least the disc of T2 and T3 with fine minute punctures. Males of Nasutopedia borealis sp. nov. can be distinguished from N. micheneri by the face with only narrow yellow stripes on lower and lateral margins of the clypeus and the sterna of males with minute pubescence covering the surface of the sterna. The wing membrane of N. borealis sp. nov. and N. micheneri is pale brown infumated with black microtrichia; however, in N. borealis sp. nov. the area with black microtrichia extends from the apex of marginal cell to the apex of the fore wing and in N. micheneri the black microtrichia is restricted to a narrow stripe along the distal margin of the fore wing.

Description

Male (holotype). Maximum head width: 2.6; body length: 8.8; wing length, without tegula: 7.5; scape length: 0.62; F1: 0.25; F2: 0.12; F3: 0.20. Colour: Integument mostly reddish brown, almost black; head, mesosoma and legs mostly reddish brown, metasoma brownish orange. Mandibles mostly pale yellow; labrum completely yellow; clypeus reddish brown with a narrow yellow stripe throughout the lower and lateral margins; parocular area completely black; scape lightly yellow on lower third; gena completely black. Tegula completely reddish brown; wing membrane pale brown infumated with numerous brownish orange microtrichia except distal third portion of fore wing blackish infumated with numerous black microtrichia; tarsomeres brownish yellow. Metasoma mostly brownish orange, almost yellow; sterna and disc of terga pale orange, almost yellow; vertical surface of T1 and margins of T2 – T6 pale brown .

Pubescence. Mostly pale brown; pubescence of legs pale brown to dark brown; scopa completely dark brown. Mandibles with numerous long simple stout setae on lower margin (ca. 1.2× mandible width); labrum mostly glabrous with scattered simple white hairs; clypeus mostly glabrous with scattered decumbent short simple setae on lateral third; frons with very short plumose hairs (ca. 1.5× F2) intermingled with sparse simple erect setae (ca. 1× F2) on disc and antennal scrobe; gena with dense short plumose hairs, integument almost covered by pubescence; lower outer margin of eye, on genal area, with numerous long plumose whitish hairs (ca. 1× F2); lower portion of gena, close to occipital area with numerous very long fine plumose hairs (ca. 2× F2); mesoscutum with velvet-like, minute and dense pubescence intermingled with sparse long erect setae (ca. 1–1.5× F2); scutellum with numerous erect simple and plumose setae throughout of posterodorsal margin, simple setae (ca. 1.2× F2); mesepisternum with numerous long simple whitish setae (ca. 1.5–2× F2); metapostnotum smooth and shiny with sparse short plumose hairs on disc (ca. 1.5× F2), with mid line and upper and lateral margins broadly smooth; T1–T3 with very short marginal bands of plumose hairs laterally; T4 with marginal band of plumose hairs occupying about one-third of the margin laterally; T5 and T6 with dense marginal band of short plumose hairs complete; S2–S3 covered by very short pubescence (discs of S4–S5 invisible by remaining terga); S2 and S3 with a line of long simple hairs on posterior margins; S4 with a marginal decumbent band of long plumose hairs, with apices of long hairs on lateral portions converging to the centre; S5 concave and glabrous on mid portion, with short stout brownish plumose hairs restricted to lateral portions; S6 with scattered plumose erect hairs on apices.

Integument sculpture. Disc of clypeus and supraclypeal area with deep large punctures, almost contiguous (<0.5 pd); lateral third of clypeus with sparse fine minute punctures; frons disc finely punctured (ca. 2 pd); antennal scrobe with fine punctures (ca. 1 pd); parocular area mostly smooth and shiny with sparse fine minute punctures (1–2 pd); mesepisternum mostly smooth, with homogeneous sparse fine punctures (ca. 3–4 pd); mesoscutum with fine minute punctures (ca. 2 pd); disc of scutellum mostly smooth, with sparse fine punctures mostly on posterolateral margins (ca. 1–2 pd); metapostnotum mostly smooth and shiny, with large smooth margins, and sparse fine minute punctures (> 3 pd); terga completely smooth.

Structure. Lamella of pronotal collar weakly acute with lateral portions not strongly raised. Scutellum slightly bilobed.

Female (paratype ‘ DZUP\021482 ’). Maximum head width: 2.8; body length: 11.3; wing length, without tegula: 8.5; scape length: 0.6; F1: 0.25; F2: 0.12; F3:0.2. Colour: Similar to male, except head completely black; metasoma reddish orange and wing membrane as in the male holotype. Pubescence: Pubescence similar to that of male

holotype, except for the tibial scopa with white hairs on posterodistal portion; long erect setae on mesoscutum and scutellum slightly shorter than in male holotype (ca. 0.8× F2); scutellum with two distinct tufts of simple long setae (ca. 0.6× F2); mesepisternum mostly glabrous, with very short whitish hairs (ca. 0.3× F2) intermingled with longer erect stout setae (ca. 1.2× F2); terga mostly glabrous, without marginal bands on T1 , and very short marginal bands on lateral portions of T3 - T4 ; T5 with complete marginal band of simple decumbent setae . Integument sculpture: Similar to that of male. Structure: Similar to that of male, lamella of pronotum weakly acute, with lateral portions opened.

Variation

The male DZUP 021480 has the lamella of the pronotal collar acute with lateral portions raised, some specimens have the lateral portions entirely low (DZUP 025594), and most specimens have an intermediate condition with the lateral portions weakly raised.

Etymology

The name of the species refers to its northern distribution on the Andean cordillera.
