Diagnosis and comments

Nasutopedia morena sp. nov. is very similar to Nasutopedia micheneri and N. borealis sp. nov. in terms of the characters already discussed in the diagnosis, including the brownish orange metasoma ( Figure 3 ). However, N. morena sp. nov. is distinguished from the other two species by the wing membrane being completely brown infumated, slightly brownish orange. Females of Nasutopedia morena sp. nov. have the first three terga densely and finely punctured, while N. micheneri have T2 partially smooth and disc of T3 mostly smooth, and N. borealis sp. nov. have the first three terga completely smooth. The males of N. morena sp. nov. have pale yellow stripes on the margins of T4, and T5 without marginal bands of plumose hairs.

Description

Male (holotype). Maximum head width: 2.25; body length: 7.8; wing length, without tegula: 6.9; scape length: 0.53; F1: 0.20; F2: 0.25; F3: 0.17. Colour: Integument mostly reddish brown; head, mesosoma and legs mostly reddish brown. Mandibles mostly pale white; labrum completely pale white; clypeus completely reddish brown; parocular area with a faint narrow pale white stripe on lower half; scape mostly light yellow; gena with a narrow pale white stripe on lower third. Tegula completely reddish brown; wing membrane brown infumated with numerous dark brown microtrichia dispersed throughout the membrane; tarsomeres completely reddish brown. Metasoma reddish orange; margin of terga reddish orange, disc of terga pale yellow and sterna pale yellow.

Pubescence. Mostly pale brown; pubescence of legs 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 on lower margin; clypeus mostly glabrous with scattered decumbent very short hairs on lateral third; frons with sparse very short velvet hairs intermingled with numerous simple long erect setae on disc and antennal scrobe; gena with very short and sparse plumose hairs, integument visible among the hairs; mesoscutum and scutellum with sparse short velvet hairs; mesoscutum with sparse very short erect setae (ca. 0.2× F2); scutellum with numerous erect simple and plumose setae throughout of posterodorsal margin, simple setae (ca. 1.0× F2); surface of mesepisternum with sparse very short simple hairs (ca. 0.3× F2); metapostnotum with numerous very short plumose pale brown hairs almost covering its entire surface; T2–T3 with short marginal bands of brownish hairs occupying less than one-third of lateral margins; T4 with a small tuft of brownish plumose hairs on lateral margin; T5–T7 mostly glabrous, with sparse erect simple setae; S2–S3 mostly glabrous, with a simple line of pale white setae on margins; S4 with a marginal band of decumbent long plumose setae, with apices converging to disc; S5 with very short plumose blackish setae restricted to lateral portions; S6 with simple stout setae distributed on the margin of apices.

Integument sculpture. Disc of clypeus and supraclypeal area with dense large punctures, almost contiguous (0.5–1 pd), intermingled with fine micropunctures; lateral third of clypeus mostly smooth, with sparse fine minute punctures; frons disc fine punctured (ca. 0.5–1 pd), with dense minute punctures on lateral portions (<0.5 pd); mesoscutum and scutellum with dense fine minute punctures (ca. 2 pd); scutellum with few large punctures, 1–3, on posterolateral portions; surface of mesepisternum mostly smooth with sparse fine punctures (ca. 10 pd); metapostnotum with dense fine punctures (1 pd); terga completely smooth (vertical surface of T1 not visible).

Structure. Dorsal lamella of pronotal collar thinly acute, with lateral portions closed.

Female (paratype AMNH, Costa Rica, Puntarenas). Maximum head width: 2.40; body length: 8.2; wing length, without tegula: 7.7; scape length: 0.54; F1: 0.23; F2: 0.12; F3: 0.2. Colour: Similar to that of male, except for labrum pale yellow to almost pale brown, head without pale yellow stripes on lower parocular area and gena. Pubescence: Similar to that of male holotype, except for hind tibial scopa with distal portion composed by numerous white plumose hairs; mesepisternum with very short plumose decumbent whitish setae scattered on its surface and intermingled with erect long simple dark brown setae (ca. 1.2× F2); mesoscutum with scattered simple erect setae on its surface (ca. 1.0× F2), and scutellum with two tufts on posterodorsal lateral third composed by short plumose setae (ca. 0.5× F2) intermingled with erect long simple setae (ca. 3× F2); terga with very short hairs on its surface distributed on the fine minute punctures; T2 – T4 with marginal band of dark brown plumose hairs on less than one-third of margin laterally . Integument sculpture: Similar to that of male, except for numerous fine minute punctures on disc of frons; T1 – T2 completely fine minute punctured (<0.5–2 pd); disc of T3 mostly finely punctured, with lateral portions and a narrow area on posterior margin smooth; T4 – T5 densely punctured on disc and smooth on posterior half and lateral portions; disc of sterna densely punctured, and margins narrowly smooth . Structure: Lamella of pronotal collar thinly acute, with lateral portions high closed. Scutellum slightly bilobed.

Variation. The remaining female specimens have the labrum darker than the described female paratype, and some of them have the sterna also darker, almost dark brown.

Etymology

The species name morena refers to the colour of the metasoma, which is reddish orange.
