Remarks.

This species has long been known as perhaps the most widespread and common congener in northern Thailand, also showing considerable variation both in body texture and gonopod structure ( Golovatch and Enghoff 1993). The new samples add to this variation in the gonopods often with spine h rather narrow and spiniform to broadly denti- or lobiform, and spine z nearly straight to strongly unciform (Figs 34-38).
