Diagnosis and comments

Nasutopedia puncticutis sp. nov. is very similar to N. morena sp. nov. due to terga 1–3 with dense fine minute punctures throughout their surfaces, but can be distinguished from this species by the metasoma brownish black, mesepisternum with numerous short setae, and mesoscutum without distinct stout long erect setae ( Figure 4 ). One male specimen from Peru (Valle de Chanchamayo) has a pollinium of an Epidendroideae orchid on the flabellum, suggesting a possible association with floral oil-producing orchids.

Description

Male (holotype). Maximum head width: 2.2; body length: 7.9; wing length, without tegula: 7.0; scape length: 0.5; F1: 0.26; F2: 0.2; F3: 0.25. Colour: Integument mostly reddish brown. Mandibles with proximal half pale white, and distal half dark brown; labrum mostly pale white; clypeus mostly dark brown, with a very narrow pale white stripe on lower and lateral margins; parocular area with a narrow pale white stripe on lower half; scape, pedicel and flagellomeres reddish brown; gena with a narrow pale white stripe on lower third. Tegula reddish brown; wing membrane dark brown infumated with numerous dark brown microtrichia dispersed throughout the membrane; distal margin of mid and hind trochanter pale white; tarsomeres reddish brown. Metasoma bicolour – pale white and dark brown; T1–T6 with proximal half light brown and distal half brownish black; T7 light brown; T3 and T4 with pale white marks on lateral portions; S1 light brown; S2 and S3 with light brown margins and pale white disc; S4 mostly pale white with posterior margin pale brown; S5 invisible – covered by S4; S6 mostly light brown.

Pubescence. Mostly pale brown, except for whitish hairs on head, mesepisternum, marginal bands of T2 and T3, and sterna. Legs with pale brown to dark brown pubescence, and scopa blackish with postero-distal portion white plumose. Labrum with scattered hairs on surface and lower margin; clypeus with scattered short,decumbent distributed hairs on its lateral third, and sparse erect setae (ca. 1.2× F2) on its disc; frons with very short velvet hairs on antennal scrobe and scattered short, simple erect hairs on disc (ca. 0.5× F2); gena with dense short plumose hairs, integument almost covered by pubescence; mesoscutum with short velvet hairs, with sparse very short erect setae (ca. <0.5× F2); scutellum with velvet pubescence, with two very small tufts of short plumose setae on dorsolateral surfaces, with only one distinct erect simple long seta (ca. 1.2× F2); lateral and ventral mesepisternum with short whitish setae, intermingled with long erect white hairs (ca. 0.8× F2); metapostnotum covered by decumbent, very short, plumose pale brown pubescence; T1 with a very short marginal band of decumbent plumose setae on dorso-lateral margins; T2–T4 with marginal band of short plumose hairs, pale white laterally and dark brown in the upper portions, occupying less than the lateral third; T5 with margin completely glabrous; T6 with a band of dark brown plumose setae not complete. Surface of S2–S3 mostly smooth, with a row of simple pale white setae on margins; S4 with a band of decumbent long plumose setae, forming fringes of convergent setae on lateral portions; S5 with short plumose setae restricted to lateral portions; S6 with simple setae restricted to the apices.

Integument sculpture. Disc of clypeus and supraclypeal area with dense large punctures, some contiguous (<0.5 pd), intermingled with dense fine micropunctures; lateral third of clypeus with fine minute punctures (ca. 3 pd); frons disc with large punctures (ca. 0.5–1 pd), with dense fine punctures (<0.5 pd) on lateral portions; antennal scrobe with fine punctures (<1pd); parocular area mostly smooth with a very fine minute pruinose punctures (> 4 pd); mesepisternum with sparse fine punctures (> 3 pd); mesoscutum and scutellum with dense fine minute punctures (ca. 1 pd); metapostnotum mostly smooth and shiny sparse fine punctures (ca. 3 pd); terga mostly smooth, except for dense fine minute punctures (ca. 2–3 pd) on vertical surface of T1; sterna mostly smooth with very sparse fine punctures (> 5 pd).

Structure. Dorsal lamella of pronotal collar thin acute, with lateral portions closed. Scutellum slightly bilobed.

Female (paratype BBSL517257). Maximum head width: 2.3; body length: 8.1; wing length, without tegula: 7.3; scape length: 0,56; F1: 0.25; F2: 0.1; F3: 016. Colour: Similar to that of male, completely dark brown to pale brown, except discs of S2–S4 pale white, and ventral surface of F2–F10 brownish orange.

Pubescence. Similar to that of male holotype, except for lateral mesepisternum with very short plumose pale white hairs intermingled with longer brownish simple setae; metapostnotum with short velvet plumose hairs; terga with very short hairs on its surface distributed on the fine minute punctures; T1 without marginal hair bands; T2– T4 with marginal band of plumose hairs on less than lateral third.

Integument sculpture. Similar to that of male, except for numerous fine minute punctures on posterior half of lateral mesepisternum; metapostnotum with dense fine minute punctures (<1 pd), with mid line deeply sulcated; T1–T2 completely fine minute punctured (<0.5–2 pd); disc of T3 mostly fine punctured, with a smooth narrow area on posterior margin; T4–T5 densely punctured on disc and smooth on posterior half and lateral portions; disc of sterna mostly densely punctured, and margins narrowly smooth. Structure: Similar to that of male.

Variation

The terga of males and females can vary from pale white to brownish black, even in the same locality (e.g. Napo province – Huahua Sumaco).

Etymology

The species name refers to the dense fine punctures of the terga of metasoma.
