Etymology: The specific epithet alludes to the strong resemblance to A. hamatus (FAIRMAIRE & LABOULBÈNE, 1856) , most likely the sister taxon.

Description: Body length 1.8–2.2 mm; length of forebody 1.0– 1.2 mm. Coloration: whole body black; legs yellow; antennae black; mandibles and maxillary palpi dark brown.

Measurements: males: head width 0.47–0.50 mm, head length 0.32–0.33 mm, eye length 0.14 mm, length of temples 0.13–0.14 mm, pronotum width 0.49–0.51 mm, pronotum length 0.35 mm, sutural length of elytra 0.36–0.38 mm, elytral width 0.61–0.64 mm. females: head width 0.37–0.38 mm, head length 0.24–0.25 mm, eye length 0.11–0.12 mm, length of temples 0.08 mm, pronotum width 0.40–0.42 mm, pronotum length 0,28– 0.29 mm, sutural length of elytra 0.32–0.35 mm, elytral width 0.51–0.53 mm.

In size, body shape, punctuation, and microsculpture indistinguishable from A. hamatus and similar species.

: head distinctly larger, transverse (width/length 1.45– 1.57), eyes as long as, or slightly longer than temples (eye length/temple length 1.0–1.1); sternite VII ( Figs 47–48 ) similar to that of A. hamatus , with prominent spine and a small tubercle with two larger spines in front of it; sternite VIII highly modified ( Figs 49–50 ), in general respect similar to that of A. hamatus , with broad and deep emargination at base, broad emargination at apical border, interrupted in the middle by a short two-lobed process with 4–5 setae at apex of each lobe; aedeagus ( Figs 51–52 ), 0.47 mm long, nearly symmetric, elongate, with the apical flag-like part of the paramere more extended than in A. hamatus .

: head distinctly smaller, transverse (width/length 1.47– 1.59), eyes distinctly longer than temples (eye length/ temple length 1.45–1.50).

Comparative notes: Anotylus hamatoides is distinguished from all other representatives of the Anotylus tetracarinatus group with the outer edge of the front tibiae apically strongly indented only by the male primary and secondary sexual characters. The pronounced similarity to the widespread A. hamatus in the shape of the male sternites VII and VIII and in the shape of the aedeagus suggests a close relationship; most likely they represent sister taxa. Both species are distinguished especially by the shape of the apical margin of the male sternite VIII. Differences in the shape of sternite VII and the aedeagus are less pronounced, but constant.

Distribution and natural history: The species is currently known from the environs of Teghut in Lori province, North Armenia, and from the Lenkoran region in Azerbaijan. The Armenian specimens were collected with pitfall traps at elevations between approximately 890 and 1100 m.
