The specimen under consideration shows the combination of characters corresponding to the family  Monotomidae: body narrow-elongate; head prognathous; eyes lateral, entire; antennal insertions lateral, widely separated; antennae short, 10-segmented with distinct two segmented club (composed of antennomere 9 and fused antennomeres 10 and 11); fronto-clypeal suture absent; abdominal ventrites 1 and 5 longer than any of ventrites 2‒4 individually; elytra distinctly truncate apically, exposing at least one tergite; procoxal cavities widely closed externally; and mesocoxal cavities open. The fossil was assigned to the tribe  Europini within the subfamily  Monotominae based on (1) all coxae well separated; (2) procoxae rounded with hidden trochantins; (3) maxillary and labial palpi with palpomere 2 normal, i.e. not enlarged; (4) punctation on elytra not paired; (5) head without deep subantennal grooves extending behind the eyes; (6) tarsal formula 5-5- 5 in females; and (7) body shape in general and pronotum in particular not cylindrically elongate and comparatively short.</p><p>The studied inclusion is placed in the diverse and variable genus  Europs based on the combination of the following characters, which distinguish the specimen from other similar genera of the tribe  Europini occurring in the Recent Holarctic biogeographic region: (1) antennal club 2-segmented, composed of antennomere 9 and fused antennomeres 10 and 11 (club 1-segmented, composed of fused antennomeres 10 and 11 in  Leptipsius Casey, 1916;  Bactridium LeConte, 1861;  Pycnotomina Casey, 1916; and in some species of  Mimemodes Reitter, 1876); (2) long setation on ventrites absent (first abdominal ventrite with relatively long setae medially in  Mimemodes); (3) elytral punctation arranged in regular longitudinal rows (irregular elytral punctation in  Phyconomus LeConte, 1861); (4) inflexed part of elytron with three rows of punctures (four rows of punctures in  Hesperobaenus LeConte, 1861); (5) subquadrate pronotum (elongate pronotum in  Macreurops Casey, 1916); (6) shortly and distinctly setose dorsum (dorsal setation long in  Rhizophagoides Nakane et Hisamatsu, 1963); and (7) antennomere 9 about as wide as antennomere 10 (antennomere 9 narrower than antennomere 10 in  Rhizophagoides and some  Hesperobaenus). Pronotal disc with impunctate median zone, short temples, abdominal ventrite 1 with femoral lines triangularly produced, and finely crenulate pronotal lateral margins are not unique for the heterogenous genus  Europs and are considered species-specific characters within the genus.</p></div>	https://treatment.plazi.org/id/03CC150D553D0D179AECD25DDD4EF9F1	Public Domain	No known copyright restrictions apply.

Relative length ratios of abdominal ventrites 1–5 equal to 29:6:5:5:15 (measured medially). Last visible tergite densely covered with small punctation; with widely rounded apex.</p><p>Differential diagnosis.  Europs carsteni sp. nov. differs from extant species of the genus based on the following combination of characters: relatively small body size (1.8 mm); triangular femoral lines with long longitudinal linear extension produced beyond the middle of abdominal ventrite 1; pronotal disc without grooves and with wide, longitudinal, impunctate area medially (in contrast to  E. ferrugineus Reitter from Japan, sometimes placed in separate subgenus or even genus  Monotopion Reitter, 1884); elytra and pronotum with fine, semierect setae; temples short (character used in delimination of the species, however the length and shape of temples gradually can vary within several extant species of the genus and is also a secondary sex characteristic); and subquadrate pronotum.</p><p>The new fossil species can be readily distinguished from described extinct representatives of genera  Aneurops (one species in Baltic amber) and  Europs (three species in Baltic and Mexican ambers) in the finely setose dorsum and triangularly produced femoral lines with longitudinal extension.  Europs carsteni sp. nov. differs from  Rovnoeurops mckellari Alekseev et Bukejs, 2022 (Rovno amber) in medially non-impressed pronotum, and antennomeres 5–8 not strongly transverse.</p><p>Derivatio nominis. The specific epithet is a patronym; the new species is named in honor of Mr. Carsten Gröhn (Glinde, Germany), an enthusiast and specialist in Baltic amber.</p></div>	https://treatment.plazi.org/id/03CC150D553D0D139AECD6A9DD23FE34	Public Domain	No known copyright restrictions apply.
