Nasutopedia rasmusseni



Comments and diagnosis: Nasutopedia rasmusseni is only known from the male holotype. It is distinguished by the mesoscutum mostly smooth with few sparse punctures, integument completely black, pronotal lamella with lateral portions raised as a closed gutter, surface of S2 with numerous simple setae, and margins of T4 T6 with few setae on lateral portions .


Holotype male: Body length: 10.0; wing length (with tegula): 9.3; head: width, 2.75, length, 2.75; clypeus: length, 0.8, width, 1.2; lower interocular distance: 1.3; upper interocular distance: 0.15; scape: length, 0.7, width, 0.2; F1–F3, length: 0.20, 0,17, 0.20; F2 diameter: 0.22. Colour. Mostly black, except tarsomeres and hind tibia reddish brown. Wing membrane and veins dark brown infumate; microtrichia mostly dark brown; fore wing membrane pale brown infumate on apical margin. Integument sculpture. Clypeus with sparse coarse punctures, c. 1 pd.; supraclypeal area with dense coarse punctures, <1 pd.; frons with sparse coarse punctures (> 2 pd); upper paraocular area with sparse fine punctures (> 2 pd). Mesoscutum mostly smooth and shiny, with very sparse fine punctures (> 5 pd); scutellum with dense fine punctures (c. 1 pd); terga completely smooth. Mesepisternum with sparse fine punctures (> 4 pd). Pubescence. Mostly dark brown, except for scopa of hind tibia and basitarsus with pale brown plumose pubescence, almost pale yellow. Mandible with numerous simple stout setae, on proximal portion, c. 1.2¥ longer than mandible width. Labrum mostly glabrous, with few short simple hairs on lower and lateral margins; clypeus, supraclypeal area, and lower paraocular area mostly glabrous, with few sparse setae; frons, upper paraocular area, and vertex with numerous erect stout setae; lower paraocular area mostly glabrous. Mesoscutum mostly glabrous, with sparse short setae; scutellum with numerous erect stout and long setae (c. 1 ¥ F2 diameter). Mesepisternum laterally with numerous long setae (c. 1–2 ¥ F2 diameter). Terga smooth, with marginal hair bands on T3–T5, occupying less than one-third of posterior margin laterally; T6 with premarginal band of long plumose hairs. S2 with sparse short setae on surface, and dense marginal band of long simple decumbent setae; S3–S4 with dense pubescence of short setae covering most of surface, and a marginal band of simple setae; S4 with dense band of long decumbent plumose hairs; lateral portions with long convergent fringes; S5 mostly smooth, with few coarse plumose setae on lateral portions; S6 with two pre-apical bands of stout setae and numerous simple short setae on apical portion. Structure. Clypeus strongly convex; upper margin of clypeus strongly convex; post-ocellar carina low, not reaching the post-ocellar portion of vertex; pronotal collar forming a dorsal lamella with lateral portions high as a closed gutter; notaulus inconspicuous; scutellum strongly convex; mesepisternum weakly concave on upper portion, posterior to omaular area; pygidial process narrow acute; mid basitarsus less than onethird wider than long.
