Mesepisternum with long white to yellowish hairs. Propodeal corbicula incomplete, posterodorsal margin with long, white plumose hairs. Surface of corbicula with sparse, long, simple to plumose white hairs. Flocculus developed, with long white plumose hairs. Femora with mostly white hairs. Tibiae and tarsi with white to brown hairs.

Head. 1.1–1.2 times broader than long. Galea finely shagreened. Labral process trapezoidal, more or less smooth ( Fig. 11 View FIGURES 1–12 ). Clypeus weakly convex, shagreened to weakly transversely grooved, punctation somewhat coarse and shallow, with a distinct narrow impunctate midline, distance between punctures 0–1 puncture diameters ( Fig. 11 View FIGURES 1–12 ). Facial foveae shallow, of more or less uniform width, about as wide as 1/3 antennocular distance, extending from level of lower end of lateral ocellus to lower end of antennal socket or slightly below. Flagellomere 1 about 1.5 times as long as broad, about as long as 2+3 ( Fig. 26 View FIGURES21–36 ); 2–3 broader than long, 3 slightly longer than 2; the following more or less square. Distance of fovea from lateral ocellus 1.5–2 ocellus diameters. Ocelloccipital distance 3/4 ocellus diameter.

Mesosoma. Dorsolateral angle of pronotum not elevated, pronotum not carinate. Mesonotum very shiny, smooth to weakly shagreened, strongly, densely and somewhat coarsely punctured, distance between punctures 0.5 puncture diameters ( Fig. 39 View FIGURES 37–48 ). Scutellum similar, smooth, distance between punctures 0.5–1 puncture diameters ( Fig. 39 View FIGURES 37–48 ). Mesepisternum shallowly rugose-areolate, shagreened, coarsely but shallowly punctured, distance between punctures about 1 puncture diameter ( Fig. 28 View FIGURES21–36 ). Propodeal triangle rugose basally, with radial grooves at basalmost part, and finely alveolate apically ( Fig. 52 View FIGURES 49–56 ). Propodeal corbicula reticulately shagreened and impunctate. Inner side of hind femur rounded, not carinate. Hind tibial spurs more or less straight and of uniform width. Hind leg pretarsal claws bidentate. Recurrent vein 1 meeting submarginal cell 2 near its middle. Nervulus more or less interstitial.

Metasoma. Tergal discs 1–3 smooth and shiny, 4 weakly to strongly shagreened ( Figs. 61 View FIGURES 57–64 , 72). Tergal disc 1 densely, strongly and somewhat coarsely punctured, distance between punctures 0.5 puncture diameter, punctation of following discs gradually decreasing in density, depth and size ( Figs. 61 View FIGURES 57–64 , 72). Tergal marginal zones 1–4 occupying 1/4–1/2 tergal width, smooth to shagreened, punctation similar to discs but finer, hardly noticeable on tergum 4; width, shagreenation and depression of marginal zones increasing gradually from tergum 1 to 4. Pygidial plate finely alveolate, not elevated medially.

Male. Body length: 5.5 mm.

Color. Clypeus yellow except for a narrow black basolateral margin; paraocular area with small apical yellow spot, not reaching anterior tentorial pit ( Fig. 74 View FIGURES 73–87 ). Flagellomeres 2–11 black to brown posteriorly, brown to reddishorange anteriorly. Rest of body similar to female.

Pubescence. Head and mesosoma with mostly white to brownish plumose hairs. Clypeus with dense white hairs of medium length. Supraclypeal and paraocular areas and scape with white to brownish hairs of medium length and density. Genal area with short white hairs dorsally, gradually longer to very long on ventral edge. Vertex with white to brownish, short and medium hairs. Mesonotum, scutellum and metanotum with sparse, long, white to brownish hairs. Mesepisternum with very long white hairs. Propodeum with dorsolateral fringe of long white hairs. Femora and tibiae with white hairs. Tarsi with white to brownish hairs. Terga with minute inconspicuous bright hairs. Tergal marginal zones 2–4 with narrow white, strongly interrupted hair bands; 5 with continuous band of very sparse whitish to golden hairs. Prepygidial fimbria whitish to golden.

Head. 1.1–1.2 times broader than long. Galea finely shagreened. Clypeus weakly convex, smooth to weakly shagreened, moderately punctured, often with impunctate midline, distance between punctures 0.5–1.5 puncture diameters, puncture size medium ( Fig. 77 View FIGURES 73–87 ). Flagellomere 1 slightly longer than broad, about as long as 3 ( Fig. 74 View FIGURES 73–87 ); 2 broader than long; the following longer than broad. Ocelloccipital distance 3/4–1 ocellus diameter.

Mesosoma. Mesonotum and scutellum very smooth and shiny medially, shagreened peripherally, strongly and somewhat coarsely punctured, distance between punctures 1 puncture diameter ( Fig. 90 View FIGURES 88–99 ). Rest of mesosoma similar to female.

Metasoma. Similar to female, but punctation of tergum 1 slightly sparser ( Fig. 103 View FIGURES 100–107 ).

Genitalia and hidden sterna. Gonocoxites connected. Dorsal lobe of gonocoxite absent ( Fig. 116 View FIGURES 114–127 ). Basal visible half of penis valves tapering apically; apical half resembling a bird's head, slightly broadened and then tapering to a needlelike apex ( Figs. 116 View FIGURES 114–127 , 131 View FIGURES 128–138 ). Blades of gonostyli not much broadened, apex rounded ( Figs. 116 View FIGURES 114–127 , 131 View FIGURES 128–138 ). Sternite 8 columnar, narrow and elongate, apex slightly broadened ( Fig. 137 View FIGURES 128–138 ).

Differential diagnosis. A. sedumella closely resembles A. crassana inka , but differs from it as follows: body smaller, flagellomere 3 longer ( Figs. 25–26 View FIGURES21–36 , 73–74 View FIGURES 73–87 ), mesonotum smoother ( Figs. 38–39 View FIGURES 37–48 , 89–90 View FIGURES 88–99 ), mesepisternum more shallowly sculptured ( Figs. 27–28 View FIGURES21–36 ), terga 3–4 more finely punctured (Figs. 71–72), gonostyli and penis valves more slender basally ( Figs. 115–116 View FIGURES 114–127 ), and gonocoxite without dorsal lobe ( Figs. 115–116 View FIGURES 114–127 ) (see female key, couplet 6, and male key, couplet 4).
