Palaeodytes baissiensis sp. n.
Etymology: From Baisa (also known as Baissa, an alternative transliteration) fossil site; adjective in the nominative singular.
Material: Holotype PIN 4210/380 ±, beetle without head, prothorax and larger part of legs; Baisa, Buryat Republic, Russia (Early Cretaceous , approximately Hauterivian, ca. 135 mya; Zherikhin et al. 1999).
Description ( Figs 16–18 View FIGURES 16 – 18 ): Medium-sized beetle, with light underside and black elytron. Maximum body width situated at middle of metacoxae. Mesocoxae rounded, separated. Metacoxal plate 1.9 times as long as lateral lobe of metaventrite (LC/LV = 1.9). Metafemur dilated to 2/3 of its length, and then narrowed towards apex.
Measurements: Body length, probably around 10 mm; body width, 4.8 mm (5.6 mm with the displaced elytron); elytron length, 8.3 mm.
Comparison: The new species differs from P. gutta Ponomarenko, 1987 and P. sibiricus Ponomarenko, 1987 in its larger body size and black elytra; it also differs from P. sibiricus , described from the same locality, in the shape of the metafemur.
