Distribution map of Macandrewella stygiana by geographical zones
Loc:
NW Pacif. (SW Okinawa, Tokashiki Shima)
N: 1
Lg.:
(903) F: 3,23-3,84; M: 3,25-3,81; {F: 3,23-3,84; M: 3,25-3,81}
Rem.: hyperbenthic (Depths: 95-167 m).
For Ohtsuka & al. (2002, p.544) this species is closely related to M. cochinensis from off Cochin (Indian Ocean), on the basis of the structure of the male P5. It is also similar to that of M. joanae.
