038FCE7AFFCFFF88E6FFF9040FA1FDC6.taxon	diagnosis	Diagnosis. Body small, oblong-oval, covered with dark long decumbent setae; head distinctly narrower than greatest pronotal width; eyes coarsely faceted; antennae slightly reaching hind angles of pronotum; antennomeres 9 and 10 more than two times as long as wide, antennal club three-segmented; pronotum widest at base, with distinct lateral carinae; posterior pronotal angles obtuse, not embracing elytral humeri; metacoxal length less than half its width; elytra without distinct puncture rows; mesoventrite flattened; tarsal formula 3 - 4 - 4. Comparison. The new genus differs from the Western Palaearctic genus Triphyllus Dejean, 1821 by its smaller body size, antennomeres 9 and 10 longer than wide, pronotum more strongly narrowed toward the apex, and shorter elytra; from the North American genus Neotriphyllus Lawrence, Escalona, Leschen & Ślipiński, 2014 in the smaller body size, its pronotum more strongly narrowed towards the apex, its mesoventrite flattened, covered with dark and long decumbent setae. It is distinguished from the genus Litargus by the posterior pronotal angles obtuse, not embracing the elytral humeri. The new genus differs from the Eocene Crowsonium by its pronotum being broadest at the base, and by its distinct antennal club consisting of three segments.	en	Legalov, Andrei A., Vasilenko, Dmitry V., Perkovsky, Evgeny E.

038FCE7AFFCDFF8DE6FFFF640881FD5C.taxon	discussion	Discussion Half of the Hymenoptera genera in Danish amber (Viertler et al. 2023; Simutnik & Perkovsky 2023; Belokobylskij et al. 2024 a, 2024 b; Simutnik et al. 2024) are unknown in Baltic amber. The difference between the Baltic amber fauna and those of other European ambers appears mainly due to its lower presence of cryophobic insects, and / or those not directly associated with the amber forest (Legalov et al. 2024), For example, there are 46 named species of caddisflies from Rovno amber, 74 % of which are unknown from Baltic amber (Melnitsky et al. 2024 a, 2024 b, 2024 c). The proportion of beetles not directly associated with the amber forest in the Danish assemblage is not very large according to our data, and the fauna of Danish amber in terms of the number of known specimens is significantly smaller than all other European amber faunas, so that only a small part of the Danish endemics may have ended up in the amber trap. At the same time, revisions of seven subfamilies of five families, Apioninae of the Brentidae (Voss 1972; Legalov 2020, 2022), Molytinae, Cossoninae and Entiminae of the Curculionidae (Voss 1972; Legalov 2020), Galerucinae of the Chrysomelidae (Nadein et al. 2016), Pharaxonothinae of the Erotylidae (Lyubarsky et al. 2024 a) and Cryptophaginae of the Cryptophagidae (Lyubarsky et al. 2024 b, 2024 c) allowed us to identify four genera, one subgenus and ten species unknown from Baltic amber. An additional genus and three species from Danish amber were added after revision of the subfamily Omaliinae (Staphylinidae) from European amber (Shavrin et al. 2023 and references therein). It is therefore quite notable that the specimen described in this paper was designated Danekrae already in 2009 (another amber Danekrae were discussed this year in Anisyutkin et al. 2024 [DK 176] and Rasmussen et al. 2024 [DK 1073]).
