“…This includes, for instance, the absence of antennae and eyes, prolonged tibio‐tarsi, and the presence of prosternoctenidium. Ripidiinae are represented in Cretaceous Burmese amber by the genera Amberocula Batelka, Engel et Prokop and Cretaceoripidius Falin et Engel, which are similar to some extant members of the tribe Ripidiini, and the genera Paleoripiphorus Perrichot, Nel, et Néraudeau, (French amber) (Batelka et al ., , ) and Protoripidius Cai, Yin et Huang (Burmese amber) of uncertain generic affinities. It will probably be impossible in the near future to assign the longipedes larvae to one of these genera or to another, yet undescribed genus.…”

“…With 22 (or 23) genera, it represents almost half of 46 currently valid extant and extinct genera (see File S1). Moreover, Ripidiinae displays remarkable morphological and sexual variability among genera (Lawrence et al ., ), and its representatives are quite common in the fossil record (Batelka et al ., , ). However, of this known diversity, only descriptions of primary larvae of Blattivorus and Ripidius are available for comparison.…”

Extremely miniaturized longipedes insects (body length c. 0.3 mm) embedded in two pieces of Cretaceous amber from Myanmar are described and interpreted. Using inverted fluorescence and light microscopy for detailed analysis of microstructures, the inclusions were identified as primary larvae of the beetle family Ripiphoridae, subfamily Ripidiinae. While the structure of thoracic and abdominal segments including appendages corresponds well with the groundplan known in recent members of Ripidiinae, a curved prosternal ridge with prominent spines (each c. 5 m), the reduced condition of stemmata and antennae and the lack of sharp mandibles are unique features within the entire family, apparently apomorphies of the longipedes larvae. A sinuate prosternal edge with a dense row of spines (prosternoctenidium) might be homologous with 'head ctenidia' in some previously described miniaturized conicocephalate larvae, but further investigation is needed. The morphological differences between the head of longipedes larvae and extant Ripidiinae are interpreted as adaptations to different groups of hosts and life strategies. Palaeoethology of the longipedes larvae is briefly discussed. In addition, the systematic placement of conicocephalate larvae from Canadian, Myanmar and Russian Cretaceous ambers, already interpreted by various authors as primary instars within Coleopterida (assigned to either Strepsiptera or to the coleopteran Tenebrionoidea: Ripiphoridae), is discussed.

“…Different catalogues were published for Mesozoic Tenebrionidae [59], darkling beetles from ambers [34], from Dominican amber [60], etc., but a complete catalogue of Tenebrionidae was compiled by Kirejtshuk et al [39] and regularly updated on the website "Beetles (Coleoptera) and coleopterists" by Kirejtshuk and A.G. Ponomarenko [40].…”

“…The oldest known distinct representatives of Tenebrionoidea are from the Callovian/Oxfordian of the Middle/Late Jurassic, Wuhua jurassica (Wang et Zhang, 2011) [86] and Praemordella martynovi (Shchegoleva-Barovskaya, 1929) [87] and belong to the clade Mordellidae-Ripiphoridae of this superfamily [59]. Archaeoripiphorus nuwa (Hsiao et al, 2017) [88] from the same stage was originally described in Ripiphoridae but was later transferred to Tenebrionoidea familia incertae sedis [59]. Mordellid-ripiphorid beetles reach the largest proportion of the described taxa (32%) within Mesozoic Tenebrionoidea.…”

“…Mordellid-ripiphorid beetles reach the largest proportion of the described taxa (32%) within Mesozoic Tenebrionoidea. Darkling beetles reach 11%, with the predominance of Alleculinae [59]. Such imbalances in the record seem to be a result of the fossilization: Ripiphoridae and Mordellidae are small beetles, common in Burmese amber, while much larger Mesozoic tenebrionids are known from Burmese amber by a single undescribed specimen; the majority of the Mesozoic tenebrionids were described from compression prints in a stone matrix.…”

The fossil record of Tenebrionidae (excluding the Quartenary) is presented. In total, 122 fossil species, clearly belonging to the family, are known; some beetles were determined only to genus; 78 genera are listed in the fossil record, including 29 extinct genera. The great diversity of tenebrionids occurs in the Lower Cretaceous Lagerstätte of China (Yixian Formation), Middle Paleocene of France (Menat), Lower Eocene deposits of Germany (Geiseltal), Upper Eocene Baltic amber (Eastern Europe), Upper Eocene deposits of Florissant Formation (USA) and Miocene (Dominican amber). Tenebrionids of the following major lineages, including seven subfamilies, are currently known in the fossil record. These include the lagrioid branch (Lagriinae, Nilioninae), pimelioid branch (Pimeliinae), and tenebrioid branch (Alleculinae, Tenebrioninae, Diaperinae, Stenochiinae). The importance of the fossil record for evolutionary reconstructions and phylogenetic patterns is discussed. The oldest Jurassic and Early Cretaceous darkling beetles of the tenebrionoid branch consist of humid-adapted groups from the extant tribes Alleculini, Ctenopodiini (Alleculinae), and Alphitobiini (Tenebrioninae). Thus, paleontological evidence suggests that differentiation of the family started at least by the Middle Jurassic but does not indicate that xerophilic darkling beetles differentiated much earlier than mesophilic groups.

Juramordella asperula gen. et sp. nov. (Coleoptera: Tenebrionoidea) is described based on a specimen from the Middle Jurassic Daohugou Biota, Nincheng County, Inner Mongolia of China. Juramordella asperula is distinguished from other Praemordellinae mainly for roughly punctate elytra, absence of subapical or lateral ridges on all tibiae and tarsi, simple, not bilobed protarsi and mesocoxa distant from procoxa, epicoxa not anterior to metacoxa, well‐developed metafemur and absence of elongated pygidium. The morphology of Juramordella asperula demonstrates the early mordellid‐like beetles have adopted the body shape with their way of movement since the Middle Jurassic, long before their flower‐visiting behavior was established.
