Etymology. Derived from the Greek words macro, “long” and pteron, “wing”, in reference to the females being fully winged.

Description. FEMALE (habitus: Figs 44, 45View FIGURES 41–47). Length about 3.0–4.0 mm. Head ( Figs 44–47View FIGURES 41–47) usually mostly yellow to orangish except rim of torulus dark and lower parascrobal region between torulus and inner orbit at least slightly brownish and usually brown ( Fig. 47View FIGURES 41–47), and sometimes scrobal depression, interantennal prominence and frontovertex also variably dark brown. Labiomaxillary complex yellowish. Antenna ( Figs 41–45View FIGURES 41–47) with scape extensively yellow but brown basally and ventrally over compressed part to or almost to apical margin, and at least pedicel also similarly yellowish, but flagellum more variable in color pattern, rarely entirely dark except for slightly paler fl1 ( Fig. 41View FIGURES 41–47), to entirely yellow except for clava ( Fig. 42View FIGURES 41–47). Mesosoma ( Figs 48, 49View FIGURES 48–53) mostly similarly coloured as head except pronotum dorsally often somewhat darker brown ( Fig. 48View FIGURES 48–53) and often one or more of pronotal panel, propleuron, prosternum and prepectus paler to whitish-yellow, whereas mesopectus and acropleuron sometimes slightly darker, more brownish-orange ( Fig. 49View FIGURES 48–53). Legs ( Fig. 45View FIGURES 41–47) similarly coloured as mesosoma except middle leg with basal four tarsomeres paler, more whitish to yellow than orangish femur and tibia and orangish to brown apical tarsomere, and hind leg with coxa usually somewhat darker brownish, tibia with convex ventral part more orangish to brown than dorsally compressed paler, more yellowish part, and tarsus with basotarsomere more or less orangish, at least basally, and apical tarsomere variably dark brown but middle three tarsomeres similarly pale as dorsal margin of metatibia. Gaster ( Fig. 53View FIGURES 48–53) mostly similarly coloured as mesosoma except Gt1–Gt5 variably extensively darker brown dorsally to dorsomedially, particularly along posterior margins (Gt1 usually paler basally and sometimes with paler band subapically), Gt1 except basolaterally and Gt2 laterally white, and all but apical two sternites white.

Head with face ( Fig. 46View FIGURES 41–47) almost uniformly punctate-reticulate and completely setose except for scrobes or for Π-shaped bare region composed of scrobes and scrobal depression dorsally; eyes and at least frontovertex with dark hairlike setae, but interantennal prominence and at least ventral half of parascrobal region with shorter, lanceolate, white setae; scrobal depression comparatively deep ventrally and extending indistinctly to about one ocellar diameter from anterior ocellus, delimiting very slender ( Figs 46, 47View FIGURES 41–47), carinately margined, sinuate parascrobal region lateral of torulus, with minimum width of parascrobal region between torulus and inner orbit conspicuously less than width of torulus and at most about 0.25× distance between toruli; malar space about 0.25× eye height; OOL: POL: LOL: MPOD = 14: 22: 14: 13; interorbital distance about 0.4× head width. Antenna ( Figs 41–43View FIGURES 41–47) with scape about 3.6–4.3× as long as wide and compressed over most of length, widest basally and only slightly tapered apically; clava slightly longer than combined length of apical 5 funiculars to almost as long as apical 6 funiculars.

Macropterous ( Figs 44, 45View FIGURES 41–47); fore wing ( Fig. 52View FIGURES 48–53) more or less distinctly orangish-infuscate with orangish to brown hairlike setae, but somewhat more hyaline behind parastigma and about basal half of marginal vein and apically beyond level of stigmal vein. Mesonotum ( Fig. 48View FIGURES 48–53) similarly punctate-reticulate as head, with variably extensive mixture of white and dark hairlike setae, the setae sometimes mostly white except dorsally along angulate part of mesoscutal medial lobe ( Fig. 48View FIGURES 48–53: arrow), but often dark setae more extensive, including within concave medial part of mesoscutum, but at least scutellar-axillar complex with mostly dark setae; scutellum ( Fig. 48View FIGURES 48–53) teardrop shaped, length about 1.6× width and subequal to width of scutellar-axillar complex. Prepectus bare ( Fig. 49View FIGURES 48–53). Acropleuron ( Figs 49, 50View FIGURES 48–53) similarly isodiametric meshlike reticulate anteriorly and posteriorly, but with much smaller, more punctate reticulations medially just beyond setation. Metapleuron and metasternum setose ( Fig. 50View FIGURES 48–53). Front leg ( Figs 44, 45View FIGURES 41–47) with femur comparatively slender, only slightly expanded subapically such that ventral margin almost straight and dorsal length about 4× maximum width; tibia similarly slender as femur, length about 6× greatest length. Hind leg ( Fig. 45View FIGURES 41–47) with coxa similarly setose at least dorsally and ventrally, with outer surface uniformly though usually less conspicuously setose; femur almost uniformly slender; tibia conspicuously compressed with dorsal margin uniformly curved; basitarsomere subcylindrical. Propodeum with foramen archlike incurved to anteromedial margin ( Fig. 51View FIGURES 48–53).

Metasoma with petiole an almost equilateral triangle ( Fig. 51View FIGURES 48–53). Gaster ( Fig. 53View FIGURES 48–53) dorsally shiny and at most inconspicuously meshlike coriaceous except syntergum more distinctly reticulate; setose laterally but mostly bare to inconspicuously setose dorsally, Gt1 and Gt2 bare, Gt3 and Gt4 with single row of setae, and apical three tergites increasingly more extensively setose.

MALE. Unknown.

Distribution. Neotropical: Belize, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Panama, Trinidad.

Remarks. Although the flagellum is described as varying from essentially entirely dark to entirely pale except for the clava, the variation is not continuous. All females from Belize, Bolivia, Brazil, Costa Rica, Ecuador and Panama have at most fl1–fl3 pale ( Figs 41, 43, 44View FIGURES 41–47), whereas the females from French Guiana and all but one female from Trinidad have at least the basal six funiculars pale ( Fig. 42View FIGURES 41–47). The female from the Simla Research Station differs from the other females in having fl1–fl4 pale and the apical four funiculars and clava dark. However, I could find no other differences that indicate more than one species may be represented by macropterous females. Males of P. macropterum  likely closely resemble those of P. albiclava  , as discussed under the latter species.
