 Issued from : J.-M. Brylinski & L. Courcot in Bioinvasions Records, 2019, 8. [p.7, Fig.4]. Female (from 47°52'06''N, 03°55'00''W): A, ventral view of genital double-somite (DGS) and anterior surface of P5.>@ = asymmetry of postero-lateral corner of prosome; GO = genital operculum; B-C, right and left P5, respectively. Diagonal arrows = central spines. Scale bars: 100 µm (A); 10 µm (B-C). Nota: - Posterolateral corners of prosome slightly asymmetrical, left side more elongated than right side and compressed in distal part. - Urosome 4-segmented. - Genital double-somite with vental genital aperture closed off by single unarmed and asymmetrical operculum . Proximal part of ventral and lateral surfaces on right side with incomplete transverse row of spinules; left side and dorsal surface ornamented with patch of minute spinules. - P5 uniramous, 2-segmented, twisted posterioely and asymmetrical with right longer than left. Terminal part of segment 2 fringed by marginal spinules and ornamented with patch of spinules in middle of anterior surface, thicker on right leg. 1 very small central spine present distally to patch of spinules in both legs.
