Besides that I studied 13 specimens of “ A. hamatum ” from NMW, label`s data of which were published by Assing (2011, 2013) from Turkey and by Assing & Schulke (2019) from Armenia respectively.
Remarks. Anthobium melanocephalum is widely distributed in Europe. Besides that, it was recorded from Turkey by Assing (2010, 2011). Turkish records of A melanocephalum by Assing (2004) refer to A. metallicum (Assing 2013). Eppelsheim (1881) published the first record of A. melanocephalum from Caucasus (“Tbatani”).
Lathrimaeum hamatum was originally described based on two specimens from “Meskisches Gebirge” (male) and “Armenisches Gebirge” (female). Later, it was recorded from many localities of Caucasus and Turkey. During the study of the type material (holotype as in Fig. 4) and additional specimens of A. melanocephalum from Europe, Turkey and Caucasus, I not found significant morphological differences between them. Some specimens from Caucasus and Turkey has paler (yellow-brown to brown) body and slightly vary in features of punctation of the head and the pronotum. Besides that, some specimens have more pronounced mediobasal impression on the pronotum. Specimens from the Middle Europe are usually larger, darker (reddish brown, with almost black head), and with more regular punctation on the pronotum. The shape of the aedeagus is slightly variable (Figs 10–12) if compared with aedeagi of specimens from Europe (Fig. 34f in Zanetti (2012)). Thus, I synonymized A. hamatum with A. melanocephalum. Habitus as in Figs 4–5. Measurements of specimens of A. melanocephalum from Turkey and Caucasus (n=50): HL: 0.41–0.44; HW: 0.66–0.70; AL: 1.20 (holotype of A. hamatum); OL: 0.16–0.20; PL: 0.61– 0.70; PW: 1.16–1.20; ESL: 1.61–1.71; EW: 1.46–1.52; AW: 0.98–1.25; MTbL: 0.69 (holotype of A. hamatum); MTrL (holotype of A. hamatum): 0.35 (MTrL 1–4: 0.18; MTrL 5: 0.17); AedL: 0.50–0.77; TL: 3.20–4.07 (holotype of A. hamatum: 4.04). It is here recorded from Azerbaijan for the first time.
