Female ( Fig. 10 View FIGURE 10 A). Body length: 8 mm.
Color. Head, mesosoma and terga black. Legs and sterna brown to black. Dorsal side of flagellum dark brown to black; ventral side of flagellomeres 3–10 and apicoventral part of flagellomeres 1–2 orange ( Fig. 10 View FIGURE 10 BC). Wings transparent, veins brown, stigma orange.
Pubescence. Labrum and vertex with golden hairs ( Fig. 10 View FIGURE 10 B –C). Clypeus with sparse white to golden hairs of medium length ( Fig. 10 View FIGURE 10 B). Paraocular area, frons and genal area with dense white hairs of medium length ( Fig. 10 View FIGURE 10 B). Mesonotum, scutellum and metanotum with sparse, short whitish-golden hairs ( Fig. 10 View FIGURE 10 C). Mesepisternum and propodeum with long white hairs. Propodeal corbicula incomplete, posterodorsal margin with long white hairs. Surface of propodeal corbicula with long, simple white hairs. Femora with long white hairs. Tibiae and tarsi with whitish to golden hairs. Scopal hairs simple anteriorly, partly plumose posteriorly. Tergal discs with inconspicuous short thin hairs, gradually lengthening from tergum 1 to tergum 4 ( Fig. 10 View FIGURE 10 D). Marginal zone of tergum 1 bare except for lateral patches of white hair. Marginal zones of terga 2–4 with conspicuous bands of dense white hair, continuous in terga 3–4, almost continuous in tergum 2. Prepygidial fimbria whitish to light brown ( Fig. 10 View FIGURE 10 D). Sternal discs with short whitish-golden hairs; marginal zones with long white hairs.
Head ( Fig. 10 View FIGURE 10 B –C). Galea shagreened. Labral process trapezoidal. Clypeus almost flat, very smooth and shiny except at basolateral margin, sparsely and irregularly punctured, with impunctate midline, distance between punctures 0.5–3 puncture diameters, puncture size large to medium ( Fig. 10 View FIGURE 10 B). Foveae broad, occupying 1/2–2/3 of paraocular area, very broad and shallow above, narrower and deeper below, extending from level of lower half of lateral ocelli to lower end of antennal socket or slightly below ( Fig. 10 View FIGURE 10 B). Distance of fovea from lateral ocellus and ocelloccipital distance about 1 ocellus diameter ( Fig. 10 View FIGURE 10 C). Flagellomere 1 as long as 2+3; 2–3 broader than long, 2 slightly shorter than 3; 4–5 almost square ( Fig. 10 View FIGURE 10 B).
Mesosoma ( Fig. 10 View FIGURE 10 C). Dorsolateral angle of pronotum weakly elevated. Mesonotum and scutellum very shiny; anterior 1/3 of mesonotum shagreened, posterior 2/3 and scutellum smooth; disc of mesonotum and scutellum sparsely and irregularly punctured, distance between punctures 0.5–3 puncture diameters, puncture size small to medium. Propodeal triangle matt, roughened and rugose. Propodeal corbicula shagreened, not to superficially punctured. Hind leg pretarsal claws bidentate. Nervulus antefurcal.
Metasoma ( Fig. 10 View FIGURE 10 D). Terga 1–4 smooth and shiny, finely and densely punctate, distance between punctures 0.5–1.5 puncture diameters. Tergum 5 superficially shagreened, coarsely punctured, distance between punctures 0.5–2 puncture diameters. Pygidial plate flat and almost smooth.
Male ( Fig. 10 View FIGURE 10 E). Body length: 6 mm.
Color. Clypeus yellowish-white with two lateral black spots ( Fig. 10 View FIGURE 10 F). Apical part of paraocular area ivorycoloured ( Fig. 10 View FIGURE 10 F). Stigma yellowish-transparent. Flagellum, mesosoma, legs and metasoma as in female.
Pubescence. Labrum with golden hairs ( Fig. 10 View FIGURE 10 F). Clypeus, paraocular area, frons, vertex and genal area with white hairs ( Fig. 10 View FIGURE 10 F). Mesosoma with long white hairs on all sides. Trochanters, femora and tibiae with white hairs. Tarsi with whitish to golden hairs. Basal half of tergum 2 with conspicuous short white hairs; otherwise tergal discs with inconspicuous short thin hairs. Marginal zones of terga 1–6 with conspicuous bands of dense white hair, continuous on terga 2–6, discontinuous on tergum 1. Anal fimbria whitish. Sternal discs with short whitish-golden hairs; marginal zones of sterna 2–5 with conspicuous white hair bands.
Head ( Fig. 10 View FIGURE 10 F). Galea shagreened. Clypeus weakly convex, very smooth and shiny, with broad impunctate midline, distance between punctures 1–2 puncture diameters, puncture size medium. Flagellomeres 1, 3–5 slightly longer than broad, 1 slightly longer than 3; 2 broader than long. Ocelloccipital distance about 1 ocellus diameter.
Mesosoma. Similar to female.
Metasoma. Similar to female.
Genitalia and hidden sterna ( Figs. 12 View FIGURE 12 H, 13H). Gonocoxites connected, with elongate dorsal lobes. Gonostylus spatulate, apical part suddenly broadened, apex rounded. Penis valves broad, spade-shaped, with short, pointed lateral projections near visual base ( Fig. 12 View FIGURE 12 H). Sternum 8 columnar, narrow, apex shaped as inverted triangle ( Fig. 13 View FIGURE 13 H).
Differential diagnosis. A. perahia is easily distinguished from similar species of the subgenus Poliandrena (e.g. A. relata Warncke ) by several characters, especially the smaller body size, the extremely smooth and shiny, sparsely punctured clypeus and mesonotum, and the male's elongate dorsal gonocoxite lobes.
Flight period: March.
Etymology. The species is named in honor of the American pianist Murray Perahia (born 1947). The species epithet is a noun in apposition.
