Overview of the caddisflies (Insecta, Trichoptera) in mid-Cretaceous Burmese amber

The family Cretapsychidae (Insecta, Trichoptera) from mid-Cretaceous Burmese amber, with descriptions of two new species

“…In the presence of forks II, III, and V and the absence of forks I and IV in the forewings, the extinct Cretapsychidae agree with the extinct Burmapsychidae Wichard, 2021 and the extant Helicophidae Mosely, 1953. However, the Burmapsychidae differ from the Cretapsychidae in the latter's threesegmented maxillary palps in males, in the scapus being longer than the head, and in the modified flagellomeres of the antennae (Wichard 2021).…”

“…and four species were included (Wichard et al 2018;Wichard & Neumann 2019;Wichard 2021). The extinct sericostomatoid family, so far found only in Burmese amber, is characterized by the 'dysoneurid' forewing venation with the absence of forks I and IV in the forewings and absence of forks II and IV in the hindwings, as well as several characters on the body such as the spur formula 2/2/4 and the shape of the terminal segments of the palpi.…”

“…The family Dysoneuridae includes extinct genera from the Jurassic period (Sukatsheva 1968;Sukatsheva & Vassilenko 2013) whose fossilized forewings are represented in Jurassic rock impressions, but without other morphological characters of the adults. This family has been used as a 'waste basket' for extinct caddisflies with similar venation, that did not necessarily belong together taxonomically, e.g., Liadotaulius Handlirsch, 1939, Burmapsyche Wichard, Neumann, Müller & Wang, 2018, and Cretapsyche Wichard, Neumann, Müller & Wang, 2018 Based on the genus Cretapsyche and its morphological characteristics, the family Cretapsychidae Wichard, 2021…”

Two new species of the genus Archaeopolycentra (Trichoptera: Polycentropodidae) from Cretaceous Taimyr amber

“…Sixtythree species of caddisflies found in Alberta, Burmese, Lebanese, New Jersey, Taymyr, and Tennessee Cretaceous ambers. The largest numbers of species are recorded in Burmese amber, 39 species distributed among 10 families (Wichard, 2020;Wang et al, 2021;Wichard et al, 2021).…”

“…This family has the rich fossil diversity in the Paleogene resins of Europe (Ivanov et al, 2016). Six species of the family Polycentropodidae are found in Cretaceous Burmese and Taymyr ambers (Ivanov & Melnitsky, 2017;Wichard, 2020). The list of caddisfly species from Taimyr amber includes 11 species from 7 families: Archaeopolycentra zherikhini Botosaneanu et Wichard, 1983, Archaeopolycentra yantardakh Ivanov et Melnitsky, 2017, Holocentropus spurius Botosaneanu et Wichard, 1983, Taymyrodipseudon protopegasus Ivanov et Melnitsky, 2017 (Dipseudopsidae), Rhyacophila antiquissima Botosaneanu et Wichard, 1983 (Rhyacophilidae), Kliganigadukia taymyrensis Ivanov et Melnitsky, 2017, Palaeohydrobiosis siberambra Botosaneanu et Wichard, 1983, Taymyrelectron sukatshevae Botosaneanu et Wichard, 1983 (Taymyrelectronidae), Calamodontus grandaevus Botosaneanu et Wichard, 1983 (Calamoceratidae), Praeathripsodes jantar Botosaneanu et Wichard, 1983, andSiberoclea parapolaria Ivanov et Melnitsky, 2017 (Leptoceridae) (Botosaneanu & Wichard, 1983;Ivanov & Melnitsky, 2017).…”
