This is a supplement to the Burmese (Myanmar) amber checklist and bibliography covering taxa described or recorded during 2025. Up to the end of 2025, 3,218 species have been recorded from Kachin amber (excluding trace fossils and marine encrusters), of which 225 were named in 2025; 25 species have been recorded from older Hkamti amber (4 named or recorded in 2025) and 2 species from younger Tilin amber. Another 12 species were named in 2025, though it is uncertain whether they are in Kachin or Hkamti amber. In total 240 species were named from Cretaceous amber from Myanmar in 2025. Caution should be employed when using the terms ‘Kachin amber’ and ‘Burmite’ because they are not equivalent to ‘Burmese amber’. ‘Kachin amber’ should only be used for amber from Kachin State.

The zygopteran family Burmacoenagrionidae Zheng, Nel & Wang, 2019 is endemic to the west Burma Block and occurring during the mid-Cretaceous (Zheng et al ., 2019). It was considered to be a member of the Coenagrionoidea Kirby, 1890, which is the dominant group of the extant damselflies (Dijkstra et al ., 2014). Four burmacoenagrionid genera have been previously described, including Burmacoenagrion Zheng, Nel & Wang, 2019, Burmagrion Möstel, Schorr & Bechly, 2017, Burmachistigma Zheng, Nel & Wang, 2019, and Electrocoenagrion Zheng, Nel & Wang, 2019 (Möstel et al ., 2017; Zheng et al ., 2019). This indicates that Burmacoenagrionidae is the most diversified zygopteran family currently recorded in the Kachin amber (Zheng, 2020).

Two new genera and three new species of webspinners, Electroclothoda aroliata gen. et sp. nov. , Cretembia longimandibula gen. et sp. nov. and Parasorellembia grandiocula sp. nov. , are described from the Upper Cretaceous of Myanmar amber. Electroclothoda aroliata gen. et sp. nov. is classified in the Clothodidae by having symmetrical male terminalia and an undivided tenth abdominal tergum. Cretembia longimandibula gen. et sp. nov. and Parasorellembia grandiocula sp. nov. are attributed to the Scelembiidae based on their distinctive terminalia: asymmetrical male terminalia, slender left cercus and robust, hook-shaped right cercus. Furthermore, a more detailed interpretation of terminalia architecture in Scelembiidae is provided.

Rovnopholcomma wunderlichi gen. et sp. nov. is described from Eocene Rovno amber (Ukraine). The new genus is the closest relative of Succinura Wunderlich, 2008, known from the Eocene Baltic (Gdańsk Bay), Danish and Bitterfeld ambers. The controversial theridiid subfamily Pholcommatinae Simon, 1894 is here delimited and divided into two tribes: 1) Pholcommatini Simon, 1894, which includes the extant genus Pholcomma Thorell, 1869 and eight extinct genera, all known from the Eocene of Europe; and 2) Theonoini Simon, 1894, which includes the extant genera Theonoe Simon, 1881, Carniella Thaler & Steinberger, 1988 and Robertus O. Pickard-Cambridge, 1879. One of the key diagnostic characters for the newly delimited Pholcommatinae is the presence of hooded trichobothrial bases, a unique feature within the family Theridiidae.
