ABSTRACT=<p>An enigmatic cucujiform beetle, <italic>Alloterocucus atratus</italic> Li, Leschen, Liu, and Cai <bold>gen. et sp. nov.</bold>, is reported from mid-Cretaceous Burmese amber. The character combination of the new fossil is not completely consistent with any of the known cucujoid or erotyloid families. Based on our phylogenetic analyses, <italic>Alloterocucus</italic> is assigned to Cucujoidea and may be allied to Lamingtoniidae, which contains a single Australasian genus in the extant fauna. <italic>Alloterocucus</italic> shares with Lamingtoniidae a similar habitus and a series of characters, including the absence of postocular constriction, 3-segmented antennal club, externally open procoxal cavities, laterally open mesocoxal cavities, exposed pro- and mesotrochantins, and the absence of epipleural fovea and pronotal setose cavities, but differs from extant Lamingtoniidae in its apically truncate terminal maxillary palpomeres, 5-5-4 tarsi in male and absence of distinct dorsal punctation.</p><sec><title>Zoobank registration</title><p>[<ext-link ext-link-type="uri" xlink:href="https://zoobank.org/" xmlns:xlink="http://www.w3.org/1999/xlink">https://zoobank.org/</ext-link>], identifier [111CE15E-5B49-4154-9E4A-7B3A738C6D2A].</p></sec>
