“…Such long‐term morphological similarity has been found and discussed in various staphylinoid families (including Jacobsoniidae here, sensu Zhang et al ., ), particularly in some staphylinid subfamilies (e.g. Clarke & Chatzimanolis, ; Chatzimanolis et al ., ; Cai et al ., , , ; Jałoszyński & Perkovsky, ; Yamamoto & Solodovnikov, ; Cai & Huang, ; Yamamoto, ; Yamamoto et al ., ; Cai et al ., ; Jałoszyński et al ., ; Yamamoto & Takahashi, ). The extinct taxa described here, especially † P. thayerae sp.n.…”

Osoriinae is a highly diverse, globally distributed subfamily of rove beetles (Staphylinidae), but only a single Mesozoic species, Mesallotrochus longiantennatus Cai & Huang, in mid-Cretaceous Burmese amber is known (age c. 99 Ma). Leptochirini, which is primarily found in decaying wood in the tropics, is one of the four tribes of osoriine rove beetles. The diversity of cephalic tooth shapes in adults has attracted special research attention with regard to the evolution and classification of this group. Here, we report two well-preserved fossils of Leptochirini for the first time from Burmese amber. Together with M. longiantennatus, they represent the oldest osoriines, highlighting the palaeodiversity of the subfamily in Burmese amber. Based on our observations and phylogenetic analyses, a remarkable new genus and species, †Cretochirus newtoni Yamamoto gen. et sp.n., is described. Additionally, a new species, †Priochirus thayerae Yamamoto sp.n., is also described and placed in the extant genus Priochirus Sharp.†Cretochirus gen.n. has a typical body plan of Leptochirini, but it retains several primitive features that have rarely, or never, been known from modern leptochirine taxa, including simple cephalic structures with a largely depressed dorsum, undeveloped cephalic teeth, and the absence of a longitudinal median sulcus of the head, together with the only slightly crenulate external margins of the protibiae. These findings demonstrate the antiquity of Leptochirini rove beetles and even suggest a much older origin of the subfamily. Morphologically diverse leptochirines from Burmese amber also illuminate the remarkable cephalic diversity of the tribe during the Mesozoic. They were already diversified during the mid-Cretaceous in the tropical forests of Myanmar, and possibly living underneath the bark of rotten wood and logs.This published work has been registered in ZooBank, http://zoobank.org/urn:lsid: zoobank.org:pub

“…In other words, bradytely is a condition under which the rate of evolutionary changes and diversification in a specific group of the organisms becomes stagnant (Simpson, 1944). Bradytely seems relatively common among terrestrial forms of Euarthropoda, especially those which live in stable conditions for longer stretches of time (Clarke and Chatzimanolis, 2009;Yamamoto et al, 2017;Lohrmann and Engel, 2017). Stable conditions in occupied habitats seem to cause long-term conservations of morphotypes, which could, in some cases persist for hundreds of millions of years (Haug et al, 2012;Yamamoto et al, 2017).…”

“…Some groups of beetles (Coleoptera) living in hygropetric (thin layer of water covering a rock surface) or other hygrophilous (very moist) habitats have shown remarkably little change in the last 100 million years. The morphological similarity to modern-day species has led to the fact that many Cretaceous fossils have been interpreted as representatives of genera with modern representatives (Clarke and Chatzimanolis, 2009;Yamamoto et. al., 2017).…”

Non-biting midges (Chironomidae) have a fossil record reaching back into the Triassic. The non-biting midge ingroup Libanochlites Brundin, 1976, was so far known from a single species. Fossil specimens of this species came from the Cretaceous of Gondwana, more precisely from Lebanese amber (130 million years). A new species, based on fossils in Eocene Baltic amber, is so similar to the so far single species of Libanochlites that it can only be attributed to this group. This is extending the known geological range of this so far unique morphology by 80 million years. This provides us with the first case of the long-term survival ("Bradytely") of a distinct Mesozoic morphotype of a representative Diptera with aquatic larvae into the Cenozoic. Bradytely is a phenomenon describing evolutionary stasis. This represents a case of bradytely in insects with aquatic larvae and has an impact on our understanding of the Cretaceous terrestrial revolution. Primarily, this record allows us to determine conditions which are permitting the survival of the Mesozoic aquatic insects into the Palaeogene. The conditions are related to the bradytely of the insects with aquatic larvae in the temperate, subtropical forest.

Members of this family are largely restricted to humid (sub) tropical areas close to the equator (CAI et al 2018), and are found under bark, in leaf litter and decomposing logs, and sometimes fungal fruiting bodies and bat guano (LAWRENCE & LESCHEN 2010).…”

A second Chinese species of the beetle family Jacobsoniidae, Sarothrias songi sp. nov., is described from Hainan Island. The new species is compared with and separated from similar congeners, supported by illustrations of diagnostic characters. A new collection record for S. sinicus Bi & Chen, 2015 from Yunnan is given, and the genital structures of this species are illustrated for the first time.
