Heterometrus laoticus sexing

[TomasM89]

Hi. I can buy two H.laoticus . Seller sent me pics of both bottoms . Can you guys told me if their male and female ? Thanks in advance

I will take a stab at this.
First picture appears to be male(longer pectine teeth, forward pointed operculum), second picture looks female to me (shorter pectine teeth, rear pointed operculum).
However please be sure to wait for some of the more experienced members to chime in and confirm.

Yup, male and female
