The mean female size is 1.752 mm (n = 12; SD = 0.1479), the mean male size is 1.656 mm (n = 10; SD = 0.1339). The size ratio (male : female) is 0.95 (n = 7; SD = 0.0192). | | | | Rem.: | This species is characteristic for West Indo-Pacific forms.
For Sewell, 1912 (p.367) this species was very abundant in the Bay of Bengal.
According to Grice (1963, p.175), except for Chiba's (1956) statement that species is typical of cold currents in the Japan area, this species is known mostly from tropical areas especially the Indo-Pacific region.
