Holotype labeled: Tyrannothroscus rex n. sp. / HOLOTYPE /J.Muona des. 10-2015. Reported to have been found from Jantarny. Sex unknown. Embedded in clear, flat, droplet-shaped Baltic Amber piece, 30 mm x 19 mm, narrow end with drilled hole with an attached silver loop for use as a pendant. A small number of tiny plant remains are present as well ( Fig. 23 ). Diagnosis . Easily recognized by the generic characters and in the key below Description . Length 8.2 mm . Head and pronotum with relatively sparse and fine punctation, on pronotum punctures of variable size, mostly small, microsculpture dense, isodiametric ( Fig. 10 ). Elytral striae sharp, minutely punctate, interstices very wide, anteriorly flat, towards apex convex ( Fig. 9 ). Venter strongly and moderately densely punctate, densest on first and second abdominal segment, vestiture visible on abdomen only, sparse, hairs fairly long. Etymology . Tyrannothroscus rex is the largest throscid known. This in combination with the massive “eyebrows” creating an aggressive, fierce look and the wide body suggest it was a real monster among its own kind.
