03E59F343F6AFFA9913B5A008D81B3B0.taxon	etymology	ETYMOLOGY. The name of the genus is derived from ‘ electron’ and ‘ pteron’, the Greek for ‘ amber’ and ‘ wing’. Gender neuter.	en	Kazantsev, S. V. (2020): First fossil representative of the net-winged beetles genus Plateros Bourgeois, 1879 (Insecta: Coleoptera: Lycidae) from Mexican amber, with redescription of Electropteron avus gen. n., sp. n. from Dominican amber and a note on the time of origin of the family.

03E59F343F6AFFA9913B5A008D81B3B0.taxon	diagnosis	DIAGNOSIS. Electropteron gen. n. appears to be related to the extant genus Tainopteron Kazantsev, 2009, from Puerto Rico [Kazantsev, 2009], distinguishable by the flattened and distally slightly widening antennomeres 4 – 11, less transverse pronotum and more elongate elytra completely covering the folded wings (Fig. 7). The new genus is different from Leptolycus Leng et Mutchler, 1922, another Greater Antillean extant endemic [Kazantsev, 2009], by the flattened antennomeres 4 – 11 with even edges and short pubescence, transverse pronotum with explanate sides and short V-shaped prosternum (Figs 7 – 8, 10). On the other hand, Electropteron gen. n. is somewhat similar to Ceratoprion Gorham, 1884, distributed in the highlands of Central America and the Ands south to Ecuador, differing by the non-serrate antennomeres 4 – 11 and their erect pubescence and by the absence of the median longitudinal pronotal carina.	en	Kazantsev, S.

03E59F343F6AFFA9913B5A008D81B3B0.taxon	discussion	REMARKS. Electropteron avus gen. n., sp. n., which is evidently close to some of the extant Leptolycini from Hispaniola and Puerto Rico, is tentatively attributed to the same tribe, although the tribe itself with the unusually wide range of morphologies of its members [e. g., Kazantsev, 2009; 2017] may prove to represent several independent lineages. The tribe Leptolycini is confined to Central America, Greater Antilles, and mostly northern part of South America. The discovery of a representative of this group in the ca. 20 myo Dominican amber, actually in the area of the current distribution of its close relatives, gives further clues for the reconstruction of the history and phylogenetics of the family.	en	Kazantsev, S.
