“…Th e Isoptera Realm, which had a warmer climate, contained very few Rotoitidae, few aphids (oft en with strongly reduced hind wings), whereas termites and webspinners (Perkovsky et al, 2020) were abundant and diverse (webspinners at least in the south of the realm). Water insects were not used in the characterization of the realms; 70 species of Cretaceous amber caddisfl ies (Ivanov & Melnitsky, 2017Wichard & Azar, 2018;Wichard et al, 2022) appear instrumental in it.…”

Polycentropodidae constitute 55.6% of Taimyr amber caddisfly species with known males, and only 4.8% of caddisfly species with known males in Kachin amber. Micro-caddisflies obviously dominate in Taimyr amber (Archaeopolycentra, Polycentropodidae), Kachin amber (Palerasnitsynus, Psychomyiidae) and New Jersey amber (Hydroptilidae); both Psychomyiidae and Hydroptilidae are absent in Taimyr amber, Polycentropodidae are absent in New Jersey amber and rare in Kachin amber. The domination of Polycentropodidae was proposed as a new characteristics of Baeomorpha Realm, their rarity or absence proposed as a new characteristics of Isoptera Realm.

“…The known world fauna of the genus Phylocentropus includes 20 species (8 extinct, 12 extant). The extinct species include 4 in Baltic amber (Ulmer 1912) and 3 in New Jersey amber (Botosaneanu et al 1998;Wichard & Bölling 2000;Wichard & Lüer 2003), and 1 from Lebanese amber (Wichard & Azar 2017). The present distribution of extant species is disjointed, having 5 in eastern North America and 7 in eastern Asia.…”

“…The most recently discovered fossil of Phylocentropus by Wichard & Azar (2017) is also the most remarkable: †Phylocentropus succinolebanensis from Lebanese amber is the oldest fossil of Phylocentropus yet known to science, being approximately 130 Ma from the Barremain Age, and the only known species of Phylocentropus from Gondwana, as Lebanon was in the northeastern peninsula of Gondwana in the Early Cretaceous. Therefore, it is hypothetically possible that the ancestor of Phylocentropus was Gondwanan, and this is supported by the fact that among its extant fauna, Africa has greatest number of dipseudopsid genera in the world, including Dipseudopsis, Hyalopsyche, Limnoecetis, and Protodipseudopsis, of which the latter two are endemic.…”

A phylogenetic review of the three species groups of the caddisfly genus Phylocentropus Banks, proposed by Ross (1965), is provided. The Phylocentropus auriceps Species Group contains 9 species: †P. antiquus, P. auriceps, †P. cretaceous, †P. gelhausi, †P. ligulatus, †P. simplex, †P. spiniger, †P. succinolebanensis, and †P. swolenskyi,; the P. placidus Species Group, 4 species: P. carolinus, P. harrisi, P. lucidus, and P. placidus; and the P. orientalis Species Group, 7 species: P. anas, P. narumonae, P. ngoclinh, P. orientalis, P. shigae, P. tohoku, and P. vietnamellus. A hypothetical phylogenetic tree of the genus is presented along with its historic biogeography.

“…Some genera with extant representatives of caddisflies (Trichoptera) such as Ecnomus McLachlan, 1864, or Phylocentropus Banks, 1907, have ingroup species known from Early Cretaceous Lebanese amber (Wichard and Azar, 2018). Similarly genera with extant representatives of culicomorphans (Diptera), including Corethrella Coquillett, 1902, (Corethrellidae) and also Austroconops Lee, 1959, andLeptoconops Skuse, 1889, (both Ceratopogonidae) also include species described based on fossils from Lebanese amber (Szadziewski, 1995(Szadziewski, , 2008.…”

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.
