Material examined. One females dissected and mounted on glass slides (shell on the SEM stub), 2 undissected specimens in 95% alcohol, 2 specimens used for the DNA extraction), all collected from 12-15 m depth by SCUBA diving off Listvyanka, 51°51'51.3"N , 104°50'37.8"E , 12 September 2015, collectors: Igor Khanaev and Ivan Nebesnykh. Short redescription. Both LV and RV banana shaped (Fig. 4A, B) with dorsal margin rounded, strongly arched and narrow ends, posterior end narrower than the anterior one. Valve margins framed with narrow fringe. Surface smooth, with few shallow pits only centrally (Fig. 4C). Surface cuticular pores simple, without lip (Fig. 4D). Length around 1 mm. Figure 4. SEM photographs of Mazepovacandona godlewski (Mazepova, 1984). Female. A RV, lateral view B LV, lateral view C details of the fine surface ornamentation D details of the posterior end of the RV. A 1 7-segmented, with segments 3 and 4 partly fused (Fig. 5A), posterior setae thin. Male A2 with subdivided penultimate segment and t2- and t3-setae transformed into sexual bristles. Female A2 (Fig. 5B, F) with all three z-seta untransformed; G2 claw short , and only slightly exceeding margin of the terminal segment. Md-palp with 4+2 setae on the inner side, gamma seta not plumose. L6 (Fig. 5C) with basal seta reaching beyond basal segment. L7 (Fig. 5E) clearly 5-segmented; basal segment with d1- and dp-seta; no e-or f-setae, g-seta long; terminal segment with setae h2- and h3- long and h1-seta shorter, but also considerably long. UR (Fig. 5D) with long posterior seta, genital field with small semi-triangular lobe. Eyes large and dark. Figure 5. Line drawings of Mazepovacandona godlewski (Mazepova, 1984). Female.
