( Figs 7–8 View FIGURE 7 View FIGURE 8 )

Material examined. Holotype, No. 1799-6 [ CCHH], adult, male. Complete beetle inclusion is preserved in a polished piece of transparent amber with an orange shade without any further fixation. The amber piece is irregularly triangular, with maximum length about 12 mm and maximum width about 2 mm. The animal syninclusions are represented by one mite (Acari) about 0.3 mm in length.

Type strata. Baltic amber, most probable from the Eocene amber-bearing layers of Blaue Erde (Blue Earth) within the Prussian Formation; estimated age: middle-late Eocene ( Bukejs et al. 2019).

Type locality. Yantarny village (formerly Palmnicken), Sambian (Samland) Peninsula, Kaliningrad Region, western Russia .

Taxonomic assignment. This taxon in Baltic amber should be placed into Scraptiini ( Scraptiidae : Scraptiinae ) based on a combination of the following morphological characters (mentioned in original description or clearly visible in photographs): (1) body form elongate-oval with base of pronotum slightly narrower than anterior elytral margin; (2) eyes emarginate anteriorly at antennal base; (3) head constricted posteriorly; (4) terminal maxillary palpomere elongate oval with pointed apex, flattened, nearly as long as penultimate palpomere; (5) antennae 11- segmented, not clubbed, filiform; (6) antennal insertions exposed from above; (7) pronotum laterally margined; (8) procoxae subcontiguous, projecting well below prosternum; (9) elytra irregularly punctate, without transverse strigae; (10) tarsi 5-5-4 with all penultimate tarsomeres lobed; (11) tibial spurs paired, equal in length, well-developed, not serrate; (12) crenulation on tibiae and tarsi absent; and (13) abdomen with five ventrites and ventrite 1 not much longer than ventrite 2.

The ventral side of forebody is not clearly visible (e.g. labial palpomeres, prosternal process, and protrochantins), basal pits of pronotum seems to be inconspicuous (barely seen). Regardless of that and on the basis of the characteristics mentioned above, we propose that Eocene Quasianisoxya Alekseev should be removed from the family Melandryidae and transferred to Scraptiini within Scraptiidae .
