Based on the body length and the coloration, and the general shape of the aedeagus, O. muensteri is similar to the East Palaearctic O. longicorne Luze, 1906, known from north-eastern Mongolia and eastern Siberia (Shavrin 2025 b). It can be distinguished from O. longicorne by the larger, denser and coarser punctation of the forebody, slightly broader pronotum, shorter elytra, distinctly broader and longer median lobe of the aedeagus, shorter parameres with narrower preapical portions, different shape of the female accessory sclerite, and other details of the morphology of the aedeagus.	en	Shavrin, Alexey V.

Some specimens were collected in mosses (Palm & Lundberg 1993, Lundberg 2001), marshy bank of river (Palm & Lundberg 1993) or in organic remains near river (Strand 1969).	en	Shavrin, Alexey V.

B45BD70A2B238637C0C9FAA4FD31C57D.taxon	discussion	Remarks. Omalium muensteri was originally described based on an unspecified number of syntypes (“ mehreren Stücken ”) from “ … Kongsberg in der Umgebung von Christiania in Norwegen ”. I have studied 12 syntypes from FMNH and NMW, and one male from FMNH was designated as the lectotype in order to fix the identity of the name. This species is rarely found in collections. There are only several records from Norway (Bernhauer 1901; Lysholm 1912; Munster 1923; Strand 1969), Sweden (Lundberg 1984, 2001; Palm & Lundberg 1993), and Finland (Krogerus 1972). It was included in the Norwegian Red List (Ødegaard et al. 2015). Records for Caucasus and Caspian region are doubtful (Herman 2001). Luze (1906) redescribed it. Palm (1948) included O. muensteri in the key of rove beetles of Sweden. Despite this, no illustrations were provided for this species, including the aedeagus. Thus, I redescribed and illustrated it herein.	en	Shavrin, Alexey V. (2025): On some western Palaearctic species of the genus Omalium Gravenhorst, 1802 (Coleoptera: Omaliinae: Omaliini).

Zanetti (2002) attributed it to the Caesum group, designated the lectotype and provided the figure of the aedeagus. It was recorded several times from north-western and central Spain (Asturia, León and Madrid provinces), which became the basis for distributional map provided by Gamarra & Outerelo (2008). It is here recorded from Badajos, Málaga and Granada provinces of Spain for the first time.	en	Shavrin, Alexey V.

B45BD70A2B2B863DC0C9FCD3FCC2C449.taxon	discussion	Remarks. Homalium vaulogeri was originally described based on the holotype from “ Tunisie: Kairouan ”. The study of the holotype (Fig. 3) and a comparison with specimens of O. allardi revealed that based on the external morphology and the shape of the aedeagus (Fig. 12), all these specimens are conspecific. Thus, I synonymized it with the latter species. Measurements of the holotype of O. vaulogeri: HW: 0.47; HL: 0.35; OL: 0.12; TL: 0.07; AL: 0.86; PL: 0.40; PWmax: 0.67; PWmin: 0.55; ESL: 0.72; EW: 0.90; AW: 0.89; AedL: 0.44; BL: 2.76. Omalium allardi is a widespread Palaearctic species (Schülke & Smetana 2015; Shavrin 2025 b), also introduced in New Zealand (Klimaszewski et al. 1996). It is worth noting that it was recorded from North Africa, and known from Morocco, Algeria, Tunisia and Libya (Schülke & Smetana 2015).	en	Shavrin, Alexey V.

B45BD70A2B28863EC0C9FF25FB07C1D2.taxon	discussion	Remarks. Omalium deubeli was originally described from “ Bucsecs ” (Bucegi Mountains, Romania) based on two specimens. The studied type specimen (Fig. 4) from FMNH was designated as the lectotype in order to fix the identity of the name. Based on the external morphology, this specimen is conspecific with European O. funebre. Thus, it was synonymized with the latter species. Omalium funebre is known from several countries of Middle and South Europe (Schülke & Smetana 2015). It is here recorded from Moldavia for the first time.	en	Shavrin, Alexey V.
