Dendrodipnis Wollaston, 1873

Subgenus Dendrodipnis Wollaston, 1873

Taxonomic assignment. The inclusion in Baltic amber under consideration can be assigned to the family Nosodendridae based on a set of characters: (1) head prognathous, inserted into prothorax; (2) antenna 11- segmented, with a distinct, slightly asymmetrical 3-segmented club; (3) frontoclypeal suture absent; (4) antennal insertions concealed from above by frontal projections; (5) prosternal process long and extending to mesoventrite; (6) metacoxal plates well developed and complete; and (7) combined length of pro-, meso- and metathorax smaller than the maximum width of metaventrite.

The main morphological features of the studied inclusion are consistent with the diagnosis of the extant genus Nosodendron . Characters supporting assignment to this genus include: (1) prosternum in front coxae extremely shortened, shorter than the half length of prosternal process (in contrast to extinct Mesozoic genera); (2) lateral portions of prosternum separated from the medial portion by a complete boundary, distinctly lowered for the reception of protrochanters and femora (in contrast to extinct Mesozoic genera); (3) antennal club consisting of three segments (in contrast to compact 2-segmented antennal club in extant Nosoglobulus Háva ); (4) tarsomeres 2–4 slender, not distinctly lobed ventrally (in contrast to the Mesozoic Mesonosa Tihelka et al. ); and (5) body shorter than 5 mm (in contrast to extinct Basinosa Tihelka et al. with body longer than 10 mm), but longer than 3 mm (in contrast to smaller body in extant Nosoglobulus ). The studied inclusion can be further assigned to the subgenus Dendrodipnis based on: (1) antennomere 3 clearly longer than antennomeres 1–2 combined; (2) pronotum and elytra without distinct setal patches; and (3) mentum subparallel-sided.
