description: Bocchus schmalhauseni sp. nov.
(Figs 1–3, 5)
Type material. Holotype: ♀, SIZK L-119: UKRAINE: specimen in Upper Eocene Rovno amber, collected in Vladimirets district near Voronki village, Rovno region, Ukraine (SIZK). Horizon: Priabonian (35–38 Ma).
Diagnosis. Macropterous female of Bocchus (Fig. 1) with OOL more than three times as long as OPL; forewing uniformly darkened (Fig. 1); petiole distinctly visible (Fig. 1); enlarged claw (Figs 2, 3, 5) with one row of small teeth and one medial lamella on inner margin; protarsomere 5 (Figs 2, 3, 5) with inner band, one preapical lamella and no bristles.
Description of female holotype (Figs 1–3, 5). Fully winged (Fig. 1); length 3.3 mm.
Black. Antenna not visible. Head dull, apparently completely granulate, not reticulate rugose; frontal line not visible; occipital carina complete; ocelli only partly visible; OOL = 2; OPL = 7; TL = 6. Mesosoma longer than head (47:28), shorter than metasoma (47:53). Pronotum crossed by strong transverse impression, with sculpture not distinct; pronotal tubercle reaching tegula. Dorsal side of mesosoma not visible. Epicnemium concealed. Metapectal-propodeal disc apparently reticulate rugose; propodeal declivity dull and rugose. Forewing uniformly darkened (Fig. 1); distal part of 2r-rs&Rs vein longer than proximal part (18:7). Petiole very long (Fig. 1), much shorter than rest of metasoma (6:53). Proleg ratio: 17 (coxa): 9 (trochanter): 22 (femur): 22 (tibia): 12 (protarsomere 1): 2 (protarsomere 2): 2 (protarsomere 3): 13 (protarsomere 4): 17 (protarsomere 5). Enlarged claw (Figs 2, 3, 5) slightly shorter than protarsomere 5 (15:17), with one medial lamella and one row of small teeth (number not distinct) situated in the distal half. Protarsomere 5 (Figs 2, 3, 5) with inner band, one preapical lamella and no bristles. Rudimentary claw present. Arolium length about 21% of fifth protarsomere length (3.6:17). Mesoleg ratio: 12 (coxa): 5 (trochanter): 20 (femur): 19 (tibia): 26 (tarsus). Metaleg ratio: 20 (coxa): 4 (trochanter): 26 (femur): 26 (tibia): 31 (tarsus). Tibial spurs not visible.
Male. Unknown.
Remarks. The new species is attributed to the genus Bocchus mainly because it has the protarsomere 5 with an inner band and has one preapical lamella. This special shape of protarsomere 5 can be found only in Bocchus (Olmi et al. 2019).
Hosts. Unknown.
Etymology. This species is named after Ivan Ivanovich Schmalhausen, the famous evolutionary biologist.
