Material.

Holotype male, Baltic Amber, MB.I 5950, deposited in Museum für Naturkunde, Berlin.

Preservation.

The adult moth is completely preserved and clearly visible from a ventro-lateral view. Right maxillary palps and antenna covered by body, dorsal and inner side of genitalia filled by white emulsion.

Etymology.

Named in honour of Alexandr P. Rasnitsyn, the eminent Russian paleoentomologist.

Diagnosis.

Baltimartyria rasnitsyni sp. n. can be separated from Baltimartyria proavitella by segment four of maxillary palps being as long as third and second segment together, and by shortly stalked R4 and R5 in both fore- and hindwings. In Baltimartyria proavitella , the two terminal segments of the maxillary palps are as long as the third segment, and in the fore- and hindwings all terminal R branches originate separately from the cell.

Description.

Length of forewing 4 mm, length of body 3 mm; head with erect, piliform scales on vertex, ocelli pale white, scape and pedicel together as long as eye diameter, scaled, 35 barrel-shaped flagellomeres present, basal segments (1-3) with scales, subsequent segments unscaled, each flagellomere with two whorls of long sensilla trichodea, one basal and one at mid-length, ascoids not clearly visible; maxillary palps five segmented, basal segments of equal length, fourth segment longest, terminal segment short, acute and with short bristles; labial palps two-segmented, terminal segment small, rounded; mandibles present (only base visible); fore-tibia with blade- like epiphysis exhibiting an acute tip, spurs 0.0.4, basitarsus of all legs covered with short, acute and semi-erect scales, tarsal segments with terminal, pair of ventral bristles; reconstructed wing pattern in Fig. 2, venation in Fig. 1, R1 with two branches in forewing, R4 and R5 on a short common stalk from cell in both wings, (anal field of hindwing only partially visible); ventral side of abdominal segment VIII membranous (= pale brown), lateral sides sclerotised (= dark brown), vinculum deeply retracted into segment VIII (segmental limits obsolete by milky nebulae); valvae simple, elliptical and spoon-like, outer surface covered by hairs.
