In the latter group, the embolus is par- tially hidden by the ventral radix. The cymbium is usually spoon-shaped, but is truncate in some Ariamnes and in all species of the A. argyrodes group (Fig. 154). atopus * cochleaforma A ecaudatus gfl probosclfe â¼ sullana D. â cordlllera 'i'" ⢠fulvus j a rossi Map 6.
