C o m m e n t: The original description is based on a male
holotype
from "Idstevan, Kloster Kiranz... an der nördl. Grenze von
Armenien
und Azerbeidshan" and an unspecified number of
paratypes
found "an verschiedenen Fundorten in Russisch-Armenien in Höhen zwischen 2000 und
3500 m
". Four type specimens were located in the Khnzorian collection (cKal): a male labelled as the
holotype
, a female labelled as the
allotype
, and
two females
labelled as
paratypes
. The status of the specimen labelled as the
holotype
is doubtful, since the locality label does not correspond to the type locality indicated in the original description. It is, however, conspecific with a male
paratype
in the Benick collection (MHNG), which was collected in the same locality as the
allotype
and which had been examined by the second author. The
allotype
is not conspecific with the
holotype
, but belongs to
A. semialba
. A d d i t i o n a l m a t e r i a l e x a m i n e d:

R e d e s c r i p t i o n: Body length
3.2-3.9 mm
; length of forebody
1.4-1.7 mm
. Coloration: body black; legs blackish with paler tarsi; antennae black; maxillary palpi black with palpomere IV pale-yellowish.
Head weakly transverse; punctation fine and moderately dense, somewhat sparser in median dorsal portion; microsculpture distinct, composed of isodiametric meshes. Eyes approximately as long as distance from posterior margin of eye to posterior constriction of head (or nearly so). Antenna approximately 1.0-
1.1 mm
long; antennomeres IV-V approximately as long as broad or weakly transverse, VI-X of gradually increasing width and increasingly transverse, X approximately 1.5 times as broad as long, and XI as long as, or slightly longer than, the combined length of IX and X.
Pronotum 1.15-1.20 times as broad as long and 1.15-1.20 times as broad as head, broadest in anterior half; punctation and microsculpture similar to those of head; pubescence
directed posteriad along midline, predominantly transversely laterad or diagonally postero-laterad in lateral portions (
type
II).
Elytra 1.05-1.10 times as long as pronotum; punctation dense and very fine, barely noticeable in the pronounced microsculpture. Hind wings fully developed. Metatarsomere I slightly longer than metatarsomere II.
Abdomen narrower than elytra; tergites III-V with, tergite VI without anterior transverse impressions; punctation moderately dense and distinct on anterior, sparse and fine on posterior tergites; microsculpture distinct, that of tergites VI and VII predominantly composed of short transverse, or a mix of short transverse and isodiametric meshes; posterior margin of tergite VII with palisade fringe; tergite VIII subject to sexual dimorphism.
3: posterior margin of tergite VIII broadly projecting in the middle, median portion more or less truncate (
Fig. 57
); sternite VIII (
Fig. 58
) with strongly convex posterior margin; median lobe of aedeagus (
Figs 59-61
) approximately
0.4 mm
long, with bladeshaped ventral process and with more or less distinctly sclerotized internal structures; parameres
0.43-0.45 mm
long.
♀
: tergite VIII (
Fig. 62
) strongly transverse, posterior margin broadly and rather weakly convex; posterior margin of sternite VIII broadly convex, in the middle with or without very shallow concavity (
Fig. 63
); spermatheca of rather variable shape (
Figs 64-70
), proximal portion often partly semitransparent.
C o m p a r a t i v e n o t e s: For characters distinguishing this species from similar Armenian congeners see the comparative notes in the following sections.
D i s t r i b u t i o n a n d n a t u r a l h i s t o r y: The species is known from several localities in both North and South
Armenia
. The specimens were found primarily in grassland by sifting debris and roots (partly near streams), or by turning stones, at elevations of
2340-3300 m
.
