Material examined.

COBERPES 2011 stn. B1, 3 females, 1 ovigerous female; stn. B9, 6 males, 8 females, 4 ovigerous females.

Remarks.

The 22 individuals occurred in front of Ría Lagartos, Quintana Roo between 976.0 and 1040.0 m. The overall sex ratio (1 M: 2.66 F) deviates signifi cantly from the expected ratio 1:1 ( χ 2 = 4.545 with 1 degree of freedom, two-tailed (P = 0.03). The carapace length size in males ranged from 4.7 to 10.2 mm, whereas females range was 6.3-10.00 mm and in ovigerous females was 8.3 to 11.2. The material examined increased the lower bathymetric limit to 1040 m from previous range (306-573 m, Baba et al 2008). Also, it is the first record for the sector SSE Gulf of Mexico. Previous records are only for the Caribbean ( Baba et al 2008).
