Summary

Description

Drassodes saccatus; large female specimen with left male palpus. From the original description:

Collected August 10, 1906; general appearance of old female of large size, with the abdomen shrivelled as in a female that has laid eggs. The epigynum is complete and symmetrical as in a normal female. The cephalothorax and abdomen are symmetrical and the 3rd and 4th legs are alike on both sides. The right palpus is that of a female and the left that of a male with the palpal organ fully developed. The 1st and 2nd legs of the left side are slightly longer than those of the right side. the left mandible is thicker than the right and the claw slightly longer but the mandible is not elongated nor narrowed at the tip as it is in the male. Kulczynski described in 1885 an Erigone fusca Blackwall (now Oedothorax fuscus or Oreoneta brunnea) with right female + left male side. Epigynum was developed only on the right, asymmetry extended to cephalothorax, abdomen and spinnerets. the legs however were symmetrical in length, only difference being in those of the 1st pair which had the right tarsus like the female and the left like the male.
