Clypeus convex, shiny, strongly shagreened except near apex, distance between punctures 1–2 puncture diameters, punctures of medium size and depth ( Fig. 1 View FIGURE 1 F). Facial foveae long, occupying about 1/2 of paraocular area width, slightly tapering at lower part, shallow above and deepening downwards, extending from level of lower end of lateral ocellus to lower end of antennal socket ( Fig. 1 View FIGURE 1 D, H). Flagellomere 1 about 1.5 times as long as broad, shorter than or equal to 2+3; 2–3 slightly broader than long, of equal length; 4–5 almost square ( Fig. 1 View FIGURE 1 D). Distance of fovea from lateral ocellus 0.5–1 ocellus diameters. Ocelloccipital distance 1/2–3/4 ocellus diameter ( Fig. 1 View FIGURE 1 H).

Mesosoma with long white hairs, sparse on dorsal side and dense on mesepisternum. Legs with white to yellowish-white hairs. Tergal discs with short and thin, inconspicuous hairs, slightly longer on apical terga. Tergum 1 with small lateral tufts of short white hair. Terga 2–4 with white, discontinuous, weak apical hair bands, weaker on tergum 4. Tergum 5 with continuous weak apical band of sparse yellowish hairs. Anal fimbria yellowish. Sterna with white hairs, longer towards marginal zone.
Head ( Fig. 2 View FIGURE 2 H). Broader than long. Galea finely shagreened. Clypeus convex, shagreened, distance between punctures 1–2 puncture diameters, punctures of medium size and depth. Flagellomere 1 about 1.3 times as long as broad, much shorter than 2+3; 2 broader than long, slightly shorter than 3; 3–5 almost square. Ocelloccipital distance 1/2 ocellus diameter.
Mesosoma. Similar to female, but position of nervulus more variable (interstitial to strongly antefurcal).
Metasoma. Similar to female.
Genitalia and hidden sterna ( Figs. 12 View FIGURE 12 B, 13B). Dorsal lobe of gonocoxite weak, very short and rounded. Gonostylus flat, elongate, slightly broadening apically. Penis valves long and narrow, tapering apically, apex needlelike ( Fig. 12 View FIGURE 12 B). Sternum 8 columnar, elongate, ventral side with dense, long hairs, apex broadened, trapezoidal ( Fig. 13 View FIGURE 13 B).
Differential diagnosis. A. judaea is characterized by the combination of a very small body size, finely reticulated propodeal triangle, relatively broad and not much tapering facial foveae, and very weak dorsal gonocoxite lobe, which distinguishes it from most members of Aciandrena, Graecandrena and Micrandrena. Additional important features include the shiny cuticle (especially the mesonotum), convex, moderately punctured, mostly shagreened clypeus, and the female's weakly to moderately antefurcal nervulus. The female of A. judaea closely resembles that of A. israelica n. sp., but differs from it in the following characters: head and mesosoma lacking metallic hue (often present in A. israelica ), hairs covering facial fovea whitish in dorsal view (brown in A. israelica , Fig. 1 View FIGURE 1 G –H), punctation of mesonotum and especially clypeus stronger and denser ( Fig. 1 View FIGURE 1 E –F), nervulus usually more weakly antefurcal ( Fig. 2 View FIGURE 2 A –B), and shagreening of terga 1–2 stronger ( Fig. 2 View FIGURE 2 C –D).
Flight period: March –April.
Etymology. The species is named after the Judean Foothills in Israel, where it was collected. The names of the closely related species A. israelica and A. judaea allude to the neighboring biblical kingdoms of Israel and Judah, whose boundaries loosely reflect the species' currently known distributions.

Remarks. Individuals of this species were observed flying very close to the ground among patches of small, annual Sedum spp. The subgeneric classification of the species is not sufficiently clear, as it exhibits a unique combination of characters (especially those of the facial foveae, propodeal triangle, male clypeus and genitalia), which does not conform well to any particular subgenus, and appears to fall between Aciandrena and Micrandrena.
