Prepygidial as well as pygidial fimbria with bright yellowishbrown pubescence. S2–6 with sparse yellowishgrey pubescence forming weak hair fringes along apical margin. Disc of S2 with sparse brush of mediumlong hairs.
Male. BL: 7.1–7.5 mm (7.2 mm). FWL: 5.1–5.6 mm (5.4 mm).
Structure. As in female except for usual secondary sexual characteristics and as follows: Head oval, 1.3 times broader than long in frontal view. Mandibles rather short distinctly bidentate. PLR shiny, rectangular, nearly twice as broad as long. Apical margin of PLR with weak emargination in the middle. Clypeus about 1.6 times broader than long.

AS 3 1.4 times as long as broad, about as long as AS 4. AS 4 and AS 5 of equal length, nearly 1.3 times as long as broad. AS 6– AS 12 nearly 1.4 times as long as broad, AS 13 nearly twice as long as broad. Disc of scutellum stronger tesselate, punctation therefore more indistinct than in female. PT stronger wrinkled than in female. Claws distinctly bidentate. T less tesselate than in female, with more dispersed punctation (1).

Diagnosis. A. heinzi is placed in subgenus Simandrena by the following characters: Propodeal corbicula of females with distinct anterior and dorsoposterior hair fringe; LP of females completely bare; flocculus of trochanter of hind leg consisting of long and dense fringe of strongly curled hairs; clypeus of males dark coloured; shape of male genitalia, S7 and S8; penis valve of male genitalia without lateral lamella. Within subgenus Simandrena, the new species is most similar to the Central Asian A. (Simandrena) sarta Morawitz, 1876 , and the western palearctic species A. (Simandrena) mehelyi Alfken, 1936 and A. (Simandrena) combinata ( Christ, 1791) . It can be distinguished from A. sarta by the following characters (character states of A. sarta given in parentheses; all characters listed below refer to females only, because no males of A. sarta were available for comparison): clypeus strongly tessellated on disc, dull (smooth and shiny on disc); hind margin of vertex rounded (carinate); distance from hind margin of LO to hind margin of vertex about 1.5 times OD (nearly as wide (0.8 times) as LO); scutum and scutellum distinctly tesselate, weakly shiny on disc (weakly tesselate to smooth, strongly shiny); punctation on T more fine and dispersed (punctation more coarse and dense); pubescence of head, lateral parts of thorax and apical hair fringes of metasoma yellowishgrey (whitish); pubescence of scutum, scutellum and metanotum bright yellowish brown of mediumlength (whitish, short); only apical hair fringes of T3 and 4 complete, apical fringe of T2 broadly interrupted (apical hair fringes complete on T2–4); distal tarsal segments of front leg, apical part of tibia and tarsus of mid leg, as well as tibia and tarsi of hind leg, bright yellowishbrown (blackishbrown); AS 5– AS 12 bright yellowishbrown on underside (dark brownish). The new species can be separated from A. mehelyi and A. combinata as follows (character states of A. mehelyi and A. combinata given in parentheses): AS 5– AS 12 of female yellowishbrown on underside (blackishbrown); male AS 3 about 1.2 times as long as broad, distinctly longer (1.4 times) than AS 4 ( AS 3 as long as broad, slightly shorter (0.9 times) than AS 4); clypeus with impunctate median line (female), transverse wrinkles absent in both sexes (impuctate median line absent, strong transverse wrinkles developed); FOV broad, about 2.9 times OD (distinctly narrower, 2.6 times OD); PT of female with few wrinkles basally, mainly granulate (nearly completely coarsely wrinkled, only apically granulate); tarsi of all legs and hind tibia yellowish in female (blackish); lateroapical hair fringes of T1 and laterobasal hair fringes of T2 absent in female (distinctly developed); prepygidial, as well as pygidial fimbria, bright yellowishgrey (greyishbrown); punctation on T minute, dense in both sexes (coarse, honeycombed); dorsal lobe of gonocoxite weakly developed (absent).
Etymology. This species is named in honor of my beloved father Heinz Dubitzky for his wonderful support during the duration of my studies and for his broad interest in the natural world.
