ZooKeys 1134: 171–183. https://doi.org/10.3897/zookeys.1134.93999 Abstract Tree described species, Neureclipsis triangula sp. nov., Neureclipsis acuta sp. nov., and Neureclipsis obtusa sp. nov., expand the Neureclipsis cluster to six species dominating the Polycentropodidae in Burmese am‑ ber. Te new species Plectrocnemia ohlhof sp. nov. and Plectrocnemia bowangi sp. nov. of the Polycentropus cluster add to the comparatively low occurrence of Polycentropodidae in Burmese mid‑Cretaceous amber. Keywords Hukawng valley, Kachin amber, Neureclipsis cluster, Polycentropus cluster Introduction Te caddisfy family Polycentropodidae is one of the most diverse in the trichopteran suborder Annulipalpia and is distributed worldwide, today with about 891 extant species (Chamorro and Holzenthal 2011; Morse 2022). Te adults can be distinguished from species of all other families by the following combination of characters: ocelli absent in adult; antennae never longer than forewings; maxillary palpi each fve‑segmented, frst two segments short, each shorter than the third or fourth, the ffth longest and annulated; mesoscutum with a pair of rounded setal warts; mesoscutellum with a rounded setal me‑ sal wart; tibial spurs 2–3/4/4; in male genitalia inferior appendages each one‑segmented.
