[ Dromia ] wilsoni (Fulton & Grant, 1902)

Female 35 × 47.8 mm, French Polynesia, Marquesas Islands, Tahuata ( MNHN-B 26480 ). A new genus to be erected (Guinot unpubl. data). The whole thoracic sternum is short and enlarged, rather flat, without a marked posterior curvature ; the sterno-abdominal depression is wide. The female sternal sutures 7/8 are relatively short, reaching only the level of the episternites 5, remain lateral and end apart; the spermathecal apertures are terminal and rounded ( Fig. 10A ). The bulb of the spermatheca is weakly prominent, prolonged by basal thickening on half of the chamber. This chamber is rather small, not very high. The tube is very narrow on its whole length, tapering, and with terminal orifice. The thoracic skeleton ( Fig. 10B ) is characterized by the concentration of the phragmae.
