The studied amber specimen shows a combination of characters corresponding to the tribe Synchitini within the subfamily Colydiinae : (1) antennal insertions concealed dorsally; (2) antennae distinctly clubbed, finely and sparsely setose, lacking scale-like setae; (3) all tarsi tetramerous, not dilated; and (4) metacoxae separated by triangular process of abdominal ventrite 1. The new extinct species is placed in the genus Lasconotus based on: antennae 11-segmented with 3-segmented club; supraocular carina strong; finely facetted eyes large; subantennal grooves absent; antennomere 3 longer than antennomere 4; apex of protibia spinose; prosternal process not expanded apically beyond midpoint of procoxa; pronotum with paired sublateral carinae; elytra with distinct carinae; and abdominal ventrite 5 with deep preapical groove.
