Alekseev, Vitalii I., Pollock, Darren A. & Bukejs, Andris, 2019, Two new fossil representatives of Eurypinae (Coleoptera: Tenebrionoidea: Mycteridae) from Eocene Baltic amber and placement of Neopolypria nigra Abdullah, 1964, Zootaxa 4551 (1), pp. 67-78 : 74-76

Subfamily Eurypinae Thomson, 1860

( Figs. 11–13 )

Material examined. No. AWI-059 [CVIA], adult, male (ventrite 2 with sex patch), complete specimen. The beetle inclusion is preserved in an oval, medium-sized polished piece of transparent Baltic amber with orange shade without supplementary fixation (total measurements are: 23 × 12 × 6 mm). Syninclusions are represented by one Acari specimen.

Note. The beetle (total length 2.6 mm) has a triangular last maxillary palpomere, penultimate tarsomeres lobed, abdomen with five ventrites coarsely punctate, large protuberant eyes, oval protuberance on ventrite 2, antennal insertions not concealed by lateral extension of frons, subapical antennomeres transverse, pronotum without lateral carina, elytra setose and irregularly punctate, procoxae subconical and contiguous, tarsal formula 5- 5-4. All abovementioned characters allow us to assign the specimen to the subfamily Eurypinae within Mycteridae . The specimen apparently differs from both beetles described above, but the important diagnostic characters are not distinctly visible or are completely obscured on the specimen. The beetle cannot be named to genus and formally described at present, until additional conspecific specimens are discovered.
