N1 - Funding Information: This paper would never be prepared without interest to study amber inclusions from Carsten Gröhn (Hamburg) who had collected a large number of very valuable specimens, whose holotypes were forwarded to the collection of Hamburg University. The authors greatly appreciate C. Willig from the Muséum national d'histoire naturelle (Paris) for his assistance in the fluorescent microscopy study of the specimens examined and A. Smetana from Canadian National Collection of Insects, Arachnids, and Nematodes in Ottawa for providing specimens for the authors' study. An essential help in preparation of the manuscript was obtained from G. Poinar (Oregon State University, Corvallis) who checked English in its most important part and provided the authors with many valuable linguistic consultations. The studies of the first author were partly carried out under the framework of the Russian state research project № АААА-А17-117030310210-3, programme of the Presidium of the Russian Academy of Sciences “Evolution of organic world. Significance and influence of planetary processes” and the Russian Foundation of Basic Research (grant № 18-04-00243–a). The CLSM studies were performed by PC at the Centre of Microscopy and Microanalysis of Saint-Petersburg State University (research project 112–8186).

N2 - The present paper describes a new genus and species, Sorodites angustipes, that represents the first nitidulid found in Cretaceous Burmese amber. It is assigned to the Soronia-generic complex (subfamily Nitidulinae, tribe Nitidulini). This specimen differs from all known members of the family by its subcylindrical to cylindrical tarsomere 3 (not lobed as in most members of the family), the pro- and mesotarsi with lobed tarsomeres 1 and 2, and also from all members of the subfamily Nitidulinae by its antennal club having a weak dorsoventral compression. The exuvium described as probable Sorodites angustipes represents a first Mesozoic remains of preimaginal instar of the family Nitidulidae. The Soronia- and Phenolia-complexes are re-defined and clarified, and attribution of the genus Cacconia Sharp, 1890 to the second complex is confirmed.
