Trichodesma View in CoL View at ENA sp. ( Figs 3C–D View FIGURE 3 )

Material examined. One specimen of Trichodesma sp. with collection number 1771-1 [CCHH], Baltic amber, Yantarny, Kaliningrad region, Russia. Complete beetle included in small, transparent, yellow amber piece with dimensions of 11×8× 5 mm. Body length of beetle is 5.2 mm. Syninclusions consist of one small specimen of Diptera , many small pieces of organic material, and few gas vesicles.

Note. The present finding from an Eocene deposit is the first report of a fossil representative of Trichodesma . Extant species of this genus are distributed in warm climatic zones of the Nearctic, Neotropic, eastern Palaearctic, Afrotropical and northern Indomalayan regions ( Español 1966; Peck 2005; Sakai 2005; Viñolas & Masó 2007; White 1982; Zahradník 2007; Zahradník & Háva 2014b). The studied fossil specimen lacks reliable diagnostic characters and remains unnamed.
