Remarks. Recently, Shavrin (2020) provided taxonomic and faunistic data for A. atrocephalum, widespread species in the Palaearctic region. It is known from North Africa and Europe to Eastern Siberia. The species is slightly varying in the body length, the coloration, and features of the punctation of the forebody. Some Caucasian specimens can be smaller, sometimes with paler head (usually darker in many specimens). The shape of the aedeagus is slightly variable also, especially in apical portion of the median lobe and parameres, which can be narrower (Figs 7–9) or somewhat broader (Fig. 2 in Shavrin (2020)).
Lathrimaeum gracilicorne was originally described from “Nordafrika (Hammam R`iza…)” (Algeria) based on the male holotype (Fig. 1). I not found significant morphological differences with A. atrocephalum both in the shape of the body (Fig. 1) and the aedeagus (Fig. 7). Thus, A. gracilicorne was synonymized with it. Measurements of the holotype: HL: 0.40; HW: 0.65; AL: 1.24; OL: 0.17; PL: 0.57; PW: 0.90; ESL: 1.32; EW: 1.30; AW: 0.92; AedL: 0.55; TL: 2.65.
Lathrimaeum abantense was originally described from “Anatolie occientale” based on two specimens. I studied both types from IRSNB. The aedeagus of the paratype as in Fig. 8. Based on the external and internal morphological features, this species is undoubtedly belong to A. atrocephalum. Thus, I synonymized A. abantense with the latter species. Measurements of the holotype (Fig. 2) and the paratype: HL: 0.41–0.45; HW: 0.66–0.72; AL: 1.35 (holotype); OL: 0.25–0.30; PL: 0.52–0.60; PW: 0.96–1.07; ESL: 1.46–1.65; EW: 1.18–1.37; AW: 1.11–1.15; AedL: 0.62–0.70;TL: 3.16–3.65 (holotype).
Lathrimaeum urgelense was originally described from Spain based on four specimens. I studied all types from IRNSB. All males were dissected prior to the present study and placed to very dark Canadian balsam (?) on separate transparent plates. The shapes of the body and aedeagi are similar to that of other specimens of A. atrocephalum. Thus, I synonymized A. urgelense with the latter species. Measurements of the holotype (Fig. 3) and paratypes: HL: 0.36–0.37; HW: 0.58–0.60; AL: 0.93 (holotype); OL: 0.15; PL: 0.45–0.49; PW: 0.84–0.87; ESL: 1.23–1.25; EW: 1.10–1.15; AW: 0.91–0.96; AedL: 0.55–0.61;TL: 2.52–3.15 (holotype: 2.67).
It is here recorded from Morocco, Azerbaijan and Iran for the first time.
