 Issued from : J.-M. Brylinski & L. Courcot in Bioinvasions Records, 2019, 8. [p.4, Fig.2, A, C]. Female (from 47°52'06''N, 03°55'00''W): A, urosome (ventral view); C, same (lateral view ). Scale bar: 100 µm. Sp: spermatophore; DGS: genital double somite; HS: hyaline sheath; L: lappets of genital operculum; ; P: point of the hyaline sheath. Arrows: ''cryptospine'' on last prosomite. Nota: - Posterior prosomal margins slightly asymmetrical. Minute spinule present dorso-laterally on each side (demonstrated using SEM observations). - Urosome 4-segmented. - Genital double-somite symmetrical; central genital aperture framed by 2 asymmetrical and very fine lappets (only observable with SEM). - Tubular spematothore implanted directly in genital opening, attached by long tubule. - When carrying a spermatophore, the genital double-somite is partially covered by a hyaline sheath which tapers to a point dorsally; this structure appeared fixed to the right side of the genital double-somite and extends forward as far as the basal articulation of the right P4.

 Issued from : J.-M. Brylinski & L. Courcot in Bioinvasions Records, 2019, 8. [p.4, Fig.2, E, D]. Female: D-E, P5. Scale bar: 10 µm. Arrows: patch of micro-spinules. Nota: - P5 uniramous, 2-segmented; proximal segment naked, distal segment armed with 1 short central spine on middle of anterior surface; patch of very small spinules present proximally to the spine. Apical part of P5 slightly asymmetrical with row of 8-9 or 12-15 spinules on outer margin , and 6-7 or 4-5 spinules on inner margin, of right and left legs, respectively.

 Issued from : J.-M. Brylinski & L. Courcot in Bioinvasions Records, 2019, 8. [p.45 Fig.3, B]. Male: B, urosome (ventral view). Scale: 40 µm. Arrow: short process directed towards left side on the 2nd urosomite. Nota: - Posterior prosomal margin symmetrical with minute spinule (as in female). - Urosome 5-segmented. - P5 elongate and markedly asymmetrical, both legs uniramous. Right bleg slender, 4-segmented; 1st and 2nd segments short, unarmed; 3rd segment elonjgate bearing acute outer process near base, slightly curving inwards; 4th segment comprising 2 processes of unequal length. left leg 5-segmented, 1st to 3rd segments short, unarmed, 4th segment rpbust and swollen; 5th segment complex with 2 pairs of long,0 wide lamellar spines, 1 pair of long, narrow lamellar spines, and 1 row of 8 wide, amber-coloured claws directed posteriorly.
